Description

Medicament capable of cooling diamond tool bit

The technical field is as follows:

the invention relates to a medicament, in particular to a medicament capable of cooling a diamond cutter head.

Background art:

at present, the tool bit for cutting stone at home and abroad is a tool bit containing diamond particles, commonly called a diamond tool bit and is fixed on a metal saw blade, when the tool bit works, the saw blade rotating at high speed drives the diamond tool bit to rotate at the same speed, and the diamond tool bit is contacted with the stone to generate friction when cutting the stone, so that the diamond tool bit is heated and passivated, and the service life is shortened. Therefore, when cutting stone, cooling liquid is needed to reduce the temperature of the diamond tool bit in time. The initial method was to use circulating water as acoolant to carry away the heat on the diamond tips. However, due to the high rotational speed of the saw blade, the wetting and dispersing speed of water on the surface of the stone and diamond tool bit is slow, so that pure water cannot effectively cool the tool bit. To this end, a liquid coolant in the form of a water carrier has been developed, which contains sodium silicate, a surfactant similar to sodium lignosulfonate, polyacrylamide and water. The preparation method comprises collecting 50-75kg of liquid sodium silicate (25-30% sodium silicate solution), 35-50kg of surfactant (similar to sodium lignosulfonate produced by saponification of pine oil and sodium hydroxide) and 2.3-4kg of polyacrylamide, making into 50kg of mixed solution, adding water to approximately 950kg, mixing to obtain 1000kg of liquid coolant, and selling. During use, 1000kg of liquid coolant is poured into a pool containing 19 cubic volumes of water (19 tons) to form a coolant for cutting stone. The coolant is in a liquid state and has a large using amount, so that two problems are mainly caused, namely inconvenient storage, large occupied space, large transportation amount and high cost.

The invention content is as follows:

the invention aims to solve the technical problem of providing a medicament which has the advantages of small dosage, convenient storage and transportation, convenient use and low cost and can cool a diamond tool bit

The present invention has been made to solve the above problems, and an object of the present invention is to provide a solid pharmaceutical preparation comprising the following components. 10-27 parts of surfactant, 5-9 parts of flocculating agent, and 40-60 parts of sodium silicate nonahydrate or sodium pentahydrate converted into pure sodium silicate, or a mixture of the sodium silicate nonahydrate and the sodium pentahydrate.

In a first preferred embodiment of the present invention, the surfactant in the solid pharmaceutical agent is any one of sodium lignosulfonate, calcium lignosulfonate, and potassium lignosulfonate, and the flocculant is polyacrylamide.

In a second preferred embodiment of the present invention, the surfactant in the solid pharmaceutical agent is any one of sodium lauryl sulfate, sodium alkylsulfonate, sodium secondary alkylsulfonate, sodium fatty alcohol polyoxyethylene ether carboxylate, and sodium lauroyl sarcosinate, and the flocculating agent is polyacrylamide.

In a third preferred embodiment of the present invention, the surfactant in the solid pharmaceutical agent is any one of lignosulfonate, sodium lignosulfonate, calcium lignosulfonate, and potassium lignosulfonate, and the flocculant is sodium polyacrylate.

The invention relates to a method for processing and using a medicament and a principle for cooling a diamond tool bit.

The processing and using method comprises the following steps: according to the weight portion, 10-27 jin of surfactant and 5-9 jin of flocculating agent are taken and converted into 40-60 jin of pure sodium silicate, namely one of sodium nonahydrate and sodium pentahydrate or the mixture of the two. The weight of the mixture containing sodium silicate nonahydrate or sodium pentahydrate or both sodium silicate nonahydrate and sodium pentahydrate is 85-140 jin. Then crushing into powder and packaging for later use. When in use, 100 and 160 jin of medicament is poured into a water tank containing 20 tons of water, thus meeting the requirement of cooling the diamond tool bit.

The cooling principle is as follows: first, water is a natural coolant commonly used in the process industry; secondly, the sodium silicate has both lubricity and cohesiveness, and the aqueous solution of the sodium silicate is alkalescent, so that the cutter for cutting the stone is not rusted, the lubricity of the cutter is ensured, the friction force between the cutter and the stone is reduced, the effects of condensing the saw mud entering water into blocks, accelerating the precipitation and keeping the cleanness of cooling water are achieved; thirdly, the surfactant has the characteristics of small surface tension, can effectively reduce the surface tension of water and enhance the diffusion capacity of the water, so that the water is effectively diffused to the processing surfaces of the cutter and the stone, and the cooling effect of the water is fully exerted; fourthly, the flocculating agent can enable stone powder flowing into water to be rapidly precipitated when the stone is cut, so that the water can be kept clean, the due cooling effect of the water can be exerted, the stone powder precipitated at the bottom of the water tank can be conveniently and timely cleaned, and the effective capacity and cleanness of the water tank can be kept. The hydrolysis principle of the sodium silicate used by the invention is as follows:

the sodium silicate used in the invention is sodium silicate nonahydrate, or sodium silicate pentahydrate, or a mixture of the sodium silicate nonahydrate and the sodium silicate pentahydrate, and the sodium silicate in the two states is easy to dissolve in water, thereby laying a foundation for the existence of the medicament in a solid state, and having reasonable proportion and less raw material consumption. Compared with the prior art, 20 tons of cooling liquid are prepared in the same way, 1 ton of liquid cooling liquid is needed when the cooling liquid is prepared by the prior art, and the dosage of the cooling liquid prepared by the medicament of the invention is only about 50kg, which is about one twentieth of the dosage of the prior art. The coolant pulled by an original vehicle with the carrying capacity of 1 ton can be used only once, generally, a stone processing plant can work for 300 days in one year, 17 tons of liquid coolant are needed for one saw in one year, the coolant is pulled by the vehicle with the carrying capacity of 1 ton in one year for at least 17 times to meet the requirement, and the coolant is pulled by the vehicle with the carrying capacity of 1 ton in one year, so that the storage space is reduced by nearly one twentieth. Moreover, the paint has no toxicity, side effect and pollution.

The specific implementation mode is as follows:

the following examples of the invention are given to further illustrate the technical solution.

Example 1. 126Kg of the preparation was prepared. Weighing 15Kg (15 parts) of sodium lignosulfonate or calcium lignosulfonate or potassium lignosulfonate as a surfactant, 6Kg (6 parts) of polyacrylamide as a flocculant and sodium nonahydrate (N, N)_a2SiO₃.9H₂O)105Kg (equivalent to 45Kg of pure sodium silicate, accounting for 45 parts), then evenly mixing, crushing and bagging.

Example 2. 88.5Kg of the preparation was prepared. Weighing 10Kg (10 parts) of any one of sodium dodecyl sulfate, sodium alkyl sulfonate, secondary alkyl sulfonate, sodium fatty alcohol polyoxyethylene ether carboxylate and sodium lauroyl sarcosinate as a surfactant, 9Kg (9 parts) of polyacrylamide as a flocculating agent and sodium pentahydrate (N, N) as sodium dodecyl sulfate, sodium alkyl sulfonate, secondary alkyl sulfonate, sodium fatty alcohol polyoxyethylene ether carboxylate and sodium lauroyl sarcosinate_a2SiO₃.5H₂O)69.5Kg (equivalent to 40Kg of pure sodium silicate, accounting for 40 parts), then evenly mixing, crushing and bagging. Compared with example 1, the sodium dodecyl sulfate, the sodium alkyl sulfonate and the secondary alkaneSodium alkylsulfonate, sodium fatty alcohol polyoxyethylene ether carboxylate and sodium lauroyl sarcosinate are more expensive than sodium lignosulfonate, calcium lignosulfonate or potassium lignosulfonate, so that the cost is higher.

Example 3. 148.9Kg of the formulation was prepared. Weighing 20Kg (20 parts) of sodium lignosulfonate or calcium lignosulfonate or potassium lignosulfonate as a surfactant, 7Kg (7 parts) of sodium polyacrylate as a flocculant and sodium pentahydrate (N, N)_a2SiO₃.5H₂O)52.1Kg and sodium silicate nonahydrate (N)_a2SiO₃.9H₂O)69.8Kg (equivalent to 60Kg of pure sodium silicate, accounting for 60 parts), then evenly mixing, crushing and bagging. Since polypropylene is compared with example 1Sodium enoate is more expensive than polyacrylamide, so the cost is higher. And simultaneously, the content of sodium silicate pentahydrate and sodium silicate nonahydrate is higher, so that the content of pure sodium silicate is high, and the cooling effect is improved while the cost is increased.

Example 4. 134.7Kg of the formulation was prepared. 27Kg (27 parts) of sodium lignosulfonate, calcium lignosulfonate or potassium lignosulfonate as a surfactant, 9Kg (9 parts) of sodium polyacrylate as a flocculant and sodium pentahydrate(N, N) are weighed_a2SiO₃.5H₂O)52.1Kg and sodium silicate nonahydrate (N)_a2SiO₃.9H₂O)46.6Kg (50 Kg of pure sodium silicate equivalent to 50 parts), then uniformly mixing, crushing and bagging. Compared with the example 3, the price and the effect are similar.

In the same way, other embodiments can be given according to the technical solution given by the present invention. Other raw materials and contents were unchanged as compared to the above examples, while the flocculants were examples of other flocculants commonly used in the market. Or, as compared with examples 3 and 4, by replacing the surfactant sodium lignosulfonate, calcium lignosulfonate or potassium lignosulfonate with any one of sodium lauryl sulfate, sodium alkylsulfonate, secondary sodium alkylsulfonate, sodium fatty alcohol polyoxyethylene ether carboxylate and sodium lauroyl sarcosinate, and by appropriately decreasing the content within the range of the amount of the surfactant (10 to 27 parts), a cooling agent having a good effect can be produced.
