How to Distinguish EPS Cement Sandwich Wall Panels from Bad Ones

The material of EPS cement sandwich wall panels are cured by autoclaving of calcium and silicon materials in containers with certain pressure and temperature. Hydrothermal synthesis reacts to form tobermorite with stable crystal structure. The material is stable and the shrinkage rate caused by temperature and humidity is very small. The difference between light partition board and ordinary calcium silicate board is that the amount of reinforcing fibers in the board is more than 5%, so it has the advantages of low density, moisture-proof, moth-proof, mildew-proof and machinability (nailing, sawing, planing, drilling, bonding, etc.). Besides the advantages of ordinary calcium silicate board, partition board also has the advantages of high strength and dryness. Excellent performance such as shrinkage and expansion and small deflection.

EPS cement sandwich panel has excellent fireproofing performance, and will not explode and burn in open fire, nor produce smoke and toxic gas. Fire resistance test is carried out according to the national standard GB9978-1988. The fire resistance limit of the partition wall with 8 mm thickness on both sides, light steel keel and rock wool with 60 mm thickness is over 90 minutes. Light weight core material made of thin partition wall panels, middle foamed polystyrene light concrete or foam expanded perlite lightweight concrete and so on is lightweight and accorded with the wallboard with low self weight, sound insulation and adiabatic effect, fast construction speed and lower price than light steel keel.Vanhe EPS cement sandwich panel has absolute quality assurance.
