Relevant patent applications and technologies related to the present invention The detailed description of the preferred embodiments with reference to the drawings will be clearly described below.

1 is a preferred embodiment of a method for manufacturing a waste catalyst coffee brick according to the present invention, comprising a preparation step 901, an activation step 902, a cementing step 903, a molding step 904, a curing step 905, and a curing step. 906, and a test step 907.

First, the preparation step 901 is performed to prepare a water quenching furnace powder, a base activator, a waste catalyst powder, and a coffee ground powder.

In the preferred embodiment, the water quenching furnace stone powder is a water quenching furnace powder selected from the group consisting of slag. The water quenching furnace powder is cooled and sprayed with high-pressure water, granulated into granules, then dehydrated, dried, or ground, and a large amount of vitreous is generated in the process of rapid cooling, so the water quenching furnace powder has 95% vitreous, chemically active, also cemented, and Possolan.

The main components of the water quenched furnace powder are SiO ₂ , Al ₂ O ₃ , CaO, Fe ₂ O ₃ , SO ₃ and MgO, which are similar to those of general cement.

The water quenching furnace powder excited by the alkaline catalyst has better cohesive force than the three-dimensional structure made by the general cement, and can improve the hardness of the three-dimensional structure, and better resistance to chemicals, frost resistance and anti-melting. .

The alkali activator is a high alkali solution, and a solution such as sodium hydroxide (NaOH), potassium hydroxide (KOH), sodium citrate (Na ₂ SiO ₃ ) or the like is generally used. Preferably, the pH of the alkali activator must be greater than 11.5.

The waste catalyst powder and the coffee ground powder are an aggregate material, The aggregate material has a composition ratio of 95 to 80% by weight of waste catalyst powder and 5 to 20% by weight of coffee grounds powder. The spent catalyst powder is selected from the group consisting of zeolite catalysts used in oil refining. Zeolite catalyst is a non-hazardous business waste. Its composition is similar to that of ceramic building materials. It has excellent heat resistance after calcination and can be applied to heat-resistant or heat-insulating materials.

However, the zeolite catalyst is a refining waste having a pungent odor. The inventors used the coffee ground powder to remove the odor of the zeolite catalyst, and the pungent odor of the zeolite catalyst is effectively slowed down when added at 5%. 20% coffee grounds powder can meet the odor requirements.

The activation step 902 is then performed, using the alkali activator to excite the agglomeration ability of the aluminosilicate mineral and forming a cementitious material. The fineness of the water quenching furnace powder is 4500-6500 cm ² /g, and the fineness of the alkali activator is 4000-5500 cm ² /g. When the fineness is finer, the polymerization speed is increased, and the cementing material is also thicker. Thick, coagulation time will also be shortened. However, when the fineness is too fine, the pores in the product become more and the structural strength is lowered.

The cementing technology used in this case is different from that of general cement. The cementing material in this case uses alkali activation technology to catalyze the alkali activator. The chain structure of the alkali activator is destroyed by using a highly alkaline solution to dissociate Ca ²⁺ . The alkali activation reaction is generated, and the alkali activation reaction is divided into two stages:

The first stage is to use a high pH base activator to destroy the bond of the multi-calcium aluminosilicate mineral material, thereby converting it into barium, aluminum calcium ions, and dissolving Ca ²⁺ .

The second stage is the use of an anion or anion group (SiO ₄ , AlO ₄ ) to react with Ca ^{2+ to initiate} alkali activation and to form a hydration product of the CSH colloid.

In the preferred embodiment, the alkali activator is mixed with sodium hydroxide using sodium citrate solution (No. 3 water glass), and when contacted with the water quenching furnace powder, the Ca-O, Si-O, and Al may be destroyed. -O bond, and Ca ^{2+ is} eluted from the water quenching furnace powder.

The excitation effect of the alkali activator is closely related to the concentration. There are usually two variables to be considered, namely the alkali modulus ratio and the base equivalent. Its alkali modulus ratio is the weight ratio of cerium oxide to sodium oxide. The base equivalent is a weight percentage relative to the cementitious material, and is preferably a preferred amount added in terms of the chemical formula molecular weight of the chemical. Since the adjustment of the alkali modulus ratio and the alkali equivalent have been known to the industry, they will not be described in detail herein.

Preferably, the alkali equivalent of the cement material is set to 6% to 10%, the alkali modulus ratio is set to 1.0 to 2.0, and the liquid to rubber ratio is set to 1 to 1.67. In addition, the alkali activator and the aluminosilicate minerals must also pay attention to the liquid-to-binder ratio (L/B, also used L/S), which refers to the solution of the alkali activator and the water quenching furnace powder. The weight ratio.

Firstly, the inventors used the water quenching furnace powder to find the appropriate alkali modulus ratio in the experiment. The parameters were set to be liquid-to-gel ratio 1, 1.25, 1.67; alkali equivalent 6%, 8%, 10%; alkali modulus ratio 1.0, 1.5, 2.0. It is cured at 60 ° C for 48 hours.

Referring to Figures 2, 3 and 4, the relationship between the alkali modulus ratio and the solidification time, wherein the horizontal axis is the measurement time of initial or final condensation, and the vertical axis is the change of the alkali modulus ratio (Ms), AE is The alkali equivalent, L/B is the liquid-to-binder ratio, the Initial strip is the initial setting time, and the Final strip is the final setting time.

It can be known from the experimental results that increasing the alkali equivalent can shorten the time of initial setting or final setting, mainly because when the alkali equivalent is increased, OH ^- ions will destroy the structure of the quenching furnace powder, so that Si ⁴⁺ , Al ³⁺ and The Ca ²⁺ elution increases, accelerating the polymerization and producing a hard solid colloid, so controlling the base equivalent will control the setting time of the cementitious material.

Increasing the alkali modulus ratio can reduce the solidification time of the cement material, mainly when the alkali modulus ratio increases, the Si ⁴⁺ content of the water quenching furnace powder structure increases, and the Si/Al atom molar ratio changes, prompting polymerization. The reaction is accelerated.

And when the liquid-to-binder ratio is increased, the concentration of the alkali equivalent is diluted by the water in the alkali activator, resulting in a decrease in alkali equivalent and alkali modulus ratio, and an increase in the time of slurry coagulation.

In the experiment, the inventor will carry out the hydration and maintenance of the three-dimensional structure made of water quenching furnace stone powder for 3 days, 7 days, and 28 days, and then test the three-dimensional structure made of water quenching furnace powder. The hardness of the structure.

Referring to Figures 5, 6, and 7, the relationship between alkali equivalent, alkali modulus ratio, liquid-to-gel ratio and hardness after hydration and curing of the cement material, wherein the horizontal axis is the alkali modulus ratio (Ms) and the liquid glue Ratio (L/B) change, the vertical axis is the hardness measurement data, AE is the alkali equivalent (6%, 8%, 10%, respectively), 3 days for hydration for 3 days, 7 days for water After 7 days of treatment, 28 days for hydration for 28 days.

Referring to Table 1, the three-dimensional structure made of water quenching furnace powder was hydrated and maintained for 3 days, 7 days, and 28 days, and the hardness of the three-dimensional structure was tested.

It can be seen from the experimental results that as the alkali equivalent increases, the compressive strength increases accordingly, mainly by increasing the alkali equivalent and increasing the alkali concentration, so that a better activation effect can be obtained, and the hydroxide ions contained are compared. Many, it can quickly destroy the vitreous material in the quenched furnace stone powder, and precipitate more aluminum and antimony elements, and the hydration product CSH colloid increases, and the compressive strength is increased.

And as the number of alkali modules increases, the compressive strength increases accordingly. The main reason is that increasing the number of alkali modules can provide more SiO ₂ , which can form more CSH colloids and make the structure more dense.

In addition, as the ratio of liquid to gel decreases, the compressive strength will increase. The higher liquid-to-binder ratio will increase the moisture in the slurry, causing excessive water to remain in the slurry, causing excessive porosity. The compressive strength is lowered. In addition, the alkali activation reaction destroys the water quenching furnace with a strong alkali. The vitreous material in the stone powder will dilute the alkali value when the liquid-to-binder ratio is increased, and the polymerization efficiency will also decrease.

In the above experimental results of the water quenching furnace powder alone, it can be found that the optimum solidification time and structural strength can be obtained when the alkali modulus ratio is set to 2.0, so that the waste catalyst powder and the coffee grounds are next In the powder mixing experiment, the alkali modulus ratio (Ms) of the cementitious material used was set to 2.0.

Then, the cementing step 903 is performed, the cementing material, the waste catalyst powder, and the coffee ground powder are mixed and cemented, and a cemented mixture is formed. Preferably, the uncured cement material is rapidly mixed with the waste catalyst powder and the coffee ground powder to uniformly distribute the waste catalyst powder and the coffee ground powder to the cement material. In the actual implementation, the water quenching furnace powder, the waste catalyst powder, and the coffee ground powder may be first mixed first, and then the alkali activator is added, which should not be limited thereto.

Wherein, the cement material ratio of the cement material to the aggregate material is 3~5. The waste catalyst powder is a loose powdery soil state, and the coffee slag powder is light in weight. The inventor made the cemented mixture at a ratio of 3, 4, and 5 in the mixing experiment and tested it.

Next, the molding step 904 is performed to mold the cemented mixture into a brick structure. In the preferred embodiment, the cemented mixture is poured into a square mold of 5 cm x 5 cm x 5 cm.

Then, the curing step 905 is performed to heat the brick structure, and the condition for heating and curing is 60 ° C for 48 hours. Preferably, the brick structure is placed in a mold and entered into an oven for heating and curing.

Then performing the maintenance step 906, the brick structure is The oven is removed from the demoulding, and the brick structure is hydrated and cured so that the brick structure becomes the waste catalyst coffee brick. The time for hydration and maintenance is 3 to 56 days. In the preferred embodiment, the inventors used 3, 7, 28, and 56 days as the time for hydration maintenance.

It can be known from the above-mentioned manufacturing method of the waste catalyst coffee brick that the waste catalyst coffee brick disclosed in the present invention comprises the cement material and the aggregate material. The cementing material includes the water quenched furnace powder, and the alkali activator. The aggregate material comprises 95 to 80% by weight of waste catalyst powder, and 5 to 20% by weight of coffee grounds powder. Wherein, the cement material ratio of the cement material to the aggregate material is 3~5. Please refer to Annex 1 for the waste catalyst coffee brick entity produced by the inventor.

Referring to Figures 8, 9, and 10, the relationship between the gel time and the solidification time of the waste catalyst coffee brick, wherein the horizontal axis is the measurement time of initial setting or final setting, and the vertical axis is the bone ratio (B/ The change of A), AE is the alkali equivalent, L/B is the liquid-to-binder ratio, the Initial strip is the initial setting time, and the Final strip is the final setting time.

It can be known from the results of the solidification time measurement that the solidification time (initial setting time + final setting time) of the waste catalyst coffee brick is shortened as the alkali equivalent is increased because the polymerization reaction is intense when the alkali equivalent is increased. Therefore, the solidification time of the waste catalyst coffee brick is shortened.

The solidification time (priming time + final setting time) of the waste catalyst coffee brick also increases with the increase of the liquid-to-gel ratio, because when the liquid-to-binder ratio is increased, the alkali concentration of the alkali equivalent is caused by the alkali. The water in the activator is diluted to increase the time of solidification.

The solidification time (priming time + final setting time) of the waste catalyst coffee brick will also be shortened as the ratio of the bone to bone is increased, because the rubber bone ratio is increased. At the same time, the proportion of the cementing material in the waste catalyst coffee brick is increased, causing more alkali activators to participate in the alkali activated polymerization reaction, and the polymerization reaction is more intense, thereby shortening the solidification time of the waste catalyst coffee brick.

Finally, the test step 907 is performed to perform a compressive strength test, a water absorption test, and a heat transfer test on the waste catalyst coffee brick. In the preferred embodiment, the waste-strength coffee bricks of the compressive strength test and the water absorption test are measured by hydration treatment for 7, 28, and 56 days. The waste catalyst coffee brick for heat conduction test was measured by hydration treatment for 7, 28, and 56 days.

Referring to Figures 11, 12 and 13, respectively, when the alkali equivalent of the cement material is 6%, 8%, 10%, the relationship between the liquid-to-binder ratio and the bone-bone ratio of the structural ceramics of the waste catalyst coffee brick, wherein The horizontal axis is the set value of the bone-to-bone ratio (B/A) and the liquid-to-binder ratio (L/B), and the vertical axis is the hardness measurement data. The alkali modulus ratio (Ms) is fixed at 2.0, and the 7-day strip is hydrated. 7 days of treatment, 28 days for hydration for 28 days, 56 days for hydration for 56 days, dotted line (1) for CNS-382 ordinary bricks, the first type of brick has a compressive condition of 300kgf/cm ² , dotted line ( 2) The compressive condition of the second brick of CNS-382 ordinary brick is 200kgf/cm ² , and the broken line (3) is the compressive condition of the third brick of CNS-382 ordinary brick is 150kgf/cm ² .

Refer to Table 2 for the measurement results of the compressive strength of the waste catalyst coffee bricks in 7 days, 28 days, and 56 days.

It can be known from the results of the hardness measurement that the compressive strength of the waste catalyst coffee brick not only increases with the increase of the curing age, but also increases with the increase of the alkali equivalent, mainly when the alkali equivalent is increased, The alkali activator has a higher pH value and contains more hydroxide ions, which has stronger dissociation ability, and enhances the alkali activation reaction of the aluminum and antimony elements in the quenched furnace stone powder, resulting in an increase in strength.

And the compressive strength of the waste catalyst coffee brick increases with the decrease of the liquid-to-gel ratio, mainly because the higher liquid-to-binder ratio causes excessive polymerization of the water, which causes excessive pores in the waste catalyst coffee brick. To promote the decline in compression resistance. Therefore, in actual implementation, it is recommended to reduce the liquid-to-binder ratio to increase the structural strength of the waste catalyst coffee brick.

In addition, the compressive strength of the waste catalyst coffee brick increases as the ratio of the bone to bone increases. When the ratio of the bone to bone is 3, the proportion of the aggregate material is large, which can improve the setting time of the waste catalyst coffee brick (initial setting time + final setting time) Between the two, but the proportion of the cement material is small, the interface is increased, and the waste catalyst powder and the coffee ground powder contain oil stains, resulting in a decrease in the strength of the waste catalyst coffee brick. Therefore, in actual implementation, it is recommended to increase the bone-to-bone ratio to increase the structural strength of the waste catalyst coffee brick.

The compressive strength test of the waste catalyst coffee brick can be obtained. When the alkali equivalent is set at 6% to 10%, the liquid-to-binder ratio is set at 1.00, the cement ratio is set at 5, and the hydration curing time is set at 7 to 56. In the day, the waste catalyst coffee brick can meet the compression condition of the third brick of CNS-382 ordinary brick. Especially when the rubber-bone ratio is set at 5, the liquid-to-binder ratio is set at 1.00, and the hydration curing time is set at 7-56 days. The waste catalyst coffee bricks obtained can meet the compressive pressure of the first brick of CNS-382 ordinary brick. condition.

Referring to Figures 14, 15, and 16, respectively, the cement material has a base equivalent AE = 6%, 8%, 10%, and its liquid-to-gel ratio and bone-to-bone ratio are related to the water absorption rate of the waste catalyst coffee brick, wherein The horizontal axis is the set value of the liquid-to-binder ratio (L/B) and the bone-bone ratio (B/A), and the vertical axis is the test value of the water absorption rate. The alkali modulus ratio (Ms) is fixed at 2.0, and the 7-day strip is water. After 7 days of treatment, 28 days for hydration for 28 days, 56 days for hydration for 56 days, and the dotted line (1) is the upper limit of water absorption for the first brick of CNS-382 ordinary brick (10%).

Refer to Table 3 for the measurement results of the water absorption test conducted after the hydration and maintenance of the waste catalyst coffee bricks for 7 days, 28 days, and 56 days.

It can be known from the water absorption test results that as the alkali equivalent increases, the water absorption rate of the waste catalyst coffee brick will decrease, and the time will decrease as the hydration treatment time increases, mainly because the higher alkali equivalent will More Si-O-Si and Al-O-Al stent-like structures are produced, so that the internal structure of the waste catalyst coffee brick is more dense, so that the reduction of pores leads to a decrease in water absorption.

In addition, as the ratio of liquid to rubber decreases, the measured water absorption rate will also decrease, mainly because the low liquid-to-liquid ratio can reduce the internal moisture of the waste catalyst coffee brick, and the reduction of pores leads to a decrease in water absorption. The increase of the cement ratio will increase the proportion of the cement material, which can make the structure of the waste catalyst coffee brick more dense, resulting in a decrease in water absorption.

Please refer to Table 4 for the inventors to measure the thermal conductivity coefficient of the waste catalyst coffee bricks for 7 days, 28 days and 56 days of hydration treatment, wherein the alkali modulus ratio (Ms) is fixed at 2, the alkali equivalent (AE) is 6% and 8%, respectively. And 10%, the liquid-to-gel ratio (L/B) is 1.67, 1.25, and 1.00, respectively, and the bone-to-bone ratio (B/A) is 3, 4, and 5, respectively. The heat transfer coefficient can be used to understand the heat transfer rate of the material. The heat transfer coefficient is an important indicator of the thermal conductivity of a lightweight aggregate. The thermal conductivity of the material is closely related to the thermal insulation performance of the material to evaluate the thermal insulation and heat resistance of the material. Benefits, when the heat transfer coefficient is lower, it means that the slower the heat transfer rate of the material, the better the heat insulation performance, and the general heat transfer coefficient of the constant gravity concrete is between 1.0~1.5W/m*K.

When the alkali equivalent 6%, the liquid-to-binder ratio is 1.67, and the bone-to-binder ratio B/A=3, the waste catalyst coffee bricks are measured for 7 days, 28 days, and 56 days. The heat transfer coefficients are 0.435, 0.522 and 0.555 W/m*K, respectively. When the alkali equivalent AE was raised to 8%, the measured heat transfer coefficient was increased to 0.448, 0.530, and 0.593 W/m*K. When the alkali equivalent AE was increased to 10%, the measured heat transfer coefficient was increased to 0.466, 0.548, and 0.603 W/m*K.

It can be known from the above measurement results that the heat transfer of the waste catalyst coffee brick increases with the increase of alkali equivalent (AE), and also increases with the increase of hydration curing time, mainly because of the increase of alkali equivalent. The colloidal polycondensation hardening can be accelerated, and the internal structure is made denser, so the heat transfer speed is faster.

When the liquid-to-gel ratio is increased from 1.00 to 1.67, the heat transfer coefficient of the 7-day curing age is up to 20%, the heat transfer coefficient of 28 days is the highest, and the heat transfer coefficient of the highest is 15%. The decline in %. Therefore, the heat transfer of the waste catalyst coffee bricks tends to decrease with the increase of the liquid-to-gel ratio. In addition to the frame-like structure, the inorganic polymer itself has a better heat transfer coefficient, and the slurry is promoted by the increase of the liquid-to-gel ratio. The water content in the body increases, and the excessive water volume causes the retained water inside the slurry structure. When the water is dispersed, the remaining pores tend to reduce the rate of heat transfer coefficient.

When the bone ratio of B/A increases from 3 to 5, the heat insulation effect will increase in the fixed alkali equivalent, liquid-to-gel ratio, and hydration curing time. The measured value of the heat transfer coefficient is between 0.466 and 0.762 W. Between /m*k, the waste catalyst coffee brick disclosed in the present invention has a lower thermal conductivity than conventional constant gravity concrete (1.0 to 1.5 W/m*k).

It can be seen from the above description that the waste catalyst coffee brick of the present invention and The manufacturing method does have the following effects:

Second, good insulation

The waste catalyst coffee bricks have a heat transfer coefficient of 0.466~0.762W/m*k, and the heat transfer coefficient is lower than that of the constant heavy concrete (1.0~1.5W/m*k), which is a good thermal insulation building material. .

Third, for green building materials
