PVC foam board is divided into PVC arch extruded foam board, PVC crust foam board and PVC free foam board; PVC crust foam board surface hardness is very high, it is difficult to produce scratches, widely used in cabinets, decoration, The surface hardness of PVC free-foamed boards such as buildings is average, which is mainly used for advertising. PVC foam board not only has all the advantages of w
It is a kind of PVC low foam board. It is produced by Celuka method. Taking PVC as the main raw material, combined with stabilizers, lubricants, foaming agents, fillers, cell regulators, impact modifiers, etc., in the forming stage, it has a large surface density, high hardness, and a small intermediate density through vacuum setting The cross-sectional structure of relatively low hardness, the su
How to improve the hardness of the core layer of PVC crust foaming board? The surface hardness of foam products is usually high, but the hardness of core layer, namely foam layer, is low. How to improve the hardness of core layer One is to add less plasticizer, the other is to reduce foaming ratio and bubble pore size Secondly, the appropriate amount of calcium powder and the supplementary use
Pearl cotton (cotton) is also called LDPE polyethylene, or EPE for short. In the production process of EPE high-foaming sheet, the physical foaming agent gas is first required to be in a gaseous state in the standard state, and it is easy to liquefy under the condition of pressurization through the special high-pressure metering pump. Because EPE resin foaming is the result of the physical foa
(1) First measure the ground temperature of the construction site, if it is lower than 10 ℃, it should not be constructed; (2) 12 hours before and after construction, take necessary measures to keep the indoor temperature above 10 ℃; (3) If the construction is on cement ground, it is necessary to check whether the ground is dry enough; (4) After the construction of the cement, the strength will
The general profile formula is as follows: PVC 100 Stabilizer 3-5 CPE 8-12 ACR 0.5-1.5 CaCO3 10-30 TiO2 4-8 The formulation of PVC plastic profiles is mainly composed of PVC resin and additives, which are divided into heat stabilizers, lubricants, agents, processing modifiers, impact modifiers, fillers, aging resistance agents, colorants Wait. Before designing the PVC formula, we should fir
