The heat flow method heat transfer analysis instrument of NETZSCH, HFM 436Lambda models.
Test effect
Part test, to have done a series of experiments for raw material, is now described below by the application by China fir：
Magnesium sulfate Different adding amount is (magnesia+magnesium chloride+sulphur to chlorine oxygen magnesium-based particleboard production shadow, wherein cement-wood ratio
Sour magnesium)/wood shavings mass ratio, the ratio of mud be moisture/(magnesia+magnesium chloride+magnesium sulfate) mass ratio, fabrication process parameters
It is shown in Table 1：
The fabrication process parameters of 1. chlorine oxygen magnesium-based particieboard of table
Other technological parameters are：Hot pressing temperature：110 DEG C of hot pressing pressures：1.0MPa hot pressing time：12min, board dimension are
32*32*1.2cm。
Two big key components in the reaction system of magnesium oxychloride cementing material are MgO and MgCl2, at normal temperatures by MgO,
MgCl2And H2O reaction 518 phases of generation [5Mg (OH)2·MgCl2·8H2O] and 3l8 phases [3Mg (OH)2·MgCl2·
8H2O], MgO and MgCl2Proportioning imbalance cannot form 518 crystalline phases largely stablized, and work as MgCl2Dosage hour, product
It hardens insufficient, intensity difference can be caused, work as MgCl2When dosage is excessive, superfluous MgCl is reacted2It is free when dosage is excessive
MgCl2It can cause moisture absorption phenomenon.When content of MgO is excessive, extra MgO can also generate the moisture absorption, and generation shepardite is reacted with water
Gel.And magnesium oxychloride cementing material is combined production environment-friendly sheet, the hygroscopicity pair of magnesium oxychloride cementing material with wood materials
The dimensional stability of plank is affected, therefore this research is added to MgSO4Instead of part MgCl2To reduce the moisture absorption of plank
Property.It can be seen that with reference to table 1 and Fig. 1 with MgSO4The increase of content, the hygroscopicity of plank reduce, and work as MgSO4Additive amount is chlorine
Oxygen magnesium cementitious material more than 15% when, the hygroscopicity of plank tends towards stability, 10% or so.With reference to Fig. 3 and Fig. 4, MgSO4
When additive amount is more than 15% magnesium oxychloride cementing material, unobvious, but the interior combination of plank are influenced on the static bending strength of plank
Intensity has certain decline, therefore, it is considered that MgSO4Additive amount is best for 15% performance.
Different densities are to chlorine oxygen magnesium-based Influence of Particleboard Properties：
The target density of plank is 0.6,0.7,0.8,0.9,1.0g/cm3, the ratio of mud 0.5, cement-wood ratio 1.5 digs with China fir
Flower+(MgCl2+ water+MgSO4)+MgO sizing sequence making sheet, wherein MgO：MgCl2：MgSO4=75:10:15.The hot pressing of making sheet
Technique is 110 DEG C, pressure 1.0MPa, hot pressing time 12min of hot pressing temperature.
With reference to Fig. 4-Fig. 7 can be seen that chlorine oxygen magnesium-based Chinese Fir Particleboard elasticity modulus and static bending strength with density
Increase and increase, wherein target density 0.8g/cm3When, the average static bending strength of plank is 11.56MPa, and static bending strength is
2165MPa.Density is 0.6 and 0.7g/cm3When, internal bond strength is smaller, and mainly for plank than more loose, appearance is larger at this time
Hole, internal bond strength is not high, and with the rising of density, internal bond strength has increased trend, but density is more than 0.8g/
cm3When, variation is not apparent.Thickness swelling rate increased trend, main cause after first reducing with the presentation of density
Be because when density is smaller, plank pressure be not it is very closely knit, internal bond strength is not high at this time, soaks and easily generates expansion, and
The more big raw material wherein used of the density of plank are more, and compression factor is higher, and the stress after water suction in plank obtains centainly
Release so as to generate rebound, the bigger test specimen of density, rebound degree bigger, therefore thickness swelling rate has increase, Midst density
For 0.8g/cm3When, thickness swelling rate average value is 2.31%.
Fig. 8 is thermal conductivity factor of the different densities plank at 10-80 DEG C, and usually in 20 DEG C of room temperature, thermal conductivity factor is less than
0.233W/ (m*K) can be described as thermal insulation material, and 0.6-1.0g/cm3Chlorine oxygen magnesium-based particieboard be respectively less than 0.233W/ (m*K),
Therefore chlorine oxygen magnesium-based particieboard has certain heat-insulating property.With the increase of environment temperature, thermal conductivity factor is increased slightly.With
The increase of density, plank is more closely knit, and thermal conductivity factor also slightly increases, but remain to the standard for reaching thermal insulation material.
Different cement-wood ratios are to chlorine oxygen magnesium-based Influence of Particleboard Properties：
The target density of plank be 0.8g/cm3, the ratio of mud 0.5, cement-wood ratio 0.5,1.0,1.5,2.0,2.5,3.0, with
China fir wood shavings+(MgCl2+ water+MgSO4)+MgO sizing sequence making sheet, wherein MgO：MgCl2：MgSO4=75:10:15.Making sheet
Heat pressing process be 110 DEG C, pressure 1.0MPa, hot pressing time 12min of hot pressing temperature.
Cement-wood ratio refers to the ratio of magnesium oxychloride cementing material and wood wool weight, with the increase of cement-wood ratio, that is, increases
Resin added reduces the quality of wooden unit.It can be seen that the elasticity of chlorine oxygen magnesium-based Chinese Fir Particleboard with reference to Fig. 9-Figure 12
Modulus and static bending strength have the tendency that first increases and then decreases with the increase of cement-wood ratio, this is because magnesium oxychloride cementing material is in itself
Density be higher than wooden unit, with the increase of cement-wood ratio, magnesium oxychloride cementing material increase, wooden unit has obtained preferably
Gluing, but when cement-wood ratio is excessive, magnesium oxychloride cementing material is excessive, is easier during experiment because receiving extruding
And overflow, so as to reduce the density of plank, intensity also reduces therewith, and when cement-wood ratio is excessive, the amount of wood shavings is very few, the plate of manufacture
Material is not closely knit enough, has hole to be formed, and also results in the reduction of intensity.When cement-wood ratio is 0.5, it may appear that glue amount is insufficient, and interior combination is strong
It spends very poor, can partly occur situation about scattering after immersion, the thick bottom expansion rate that absorbs water is very big, therefore this experimental condition manufacture chlorine oxygen magnesium
Base particieboard is not suitable for.When cement-wood ratio is more than 1.5, the internal bond strength and thickness swelling rate of plank are relatively stable.
Figure 13 is thermal conductivity factor of the plank at 10-80 DEG C under the conditions of different cement-wood ratios, during cement-wood ratio 0.5-3.0, chlorine oxygen
The thermal conductivity factor of magnesium-based particieboard is respectively less than 0.233W/ (m*K), has preferable heat-insulating property.
The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof, the ordinary skill people of fields
Member, which should be appreciated that, can be modified or replaced equivalently the specific embodiment of the present invention with reference to above-described embodiment, these
Without departing from any modification of spirit and scope of the invention or equivalent replacement apply pending claims it
It is interior.
