Brief introduction of expanded perlite board--Dacheng Xiangdong Insulation Refractory Material Factory 13473696600 15731614448
Expanded perlite is a lightweight, versatile new material. It has the characteristics of light apparent density, low thermal conductivity, good chemical stability, wide temperature range, low moisture absorption capacity, non-toxic, odorless, fireproof and sound absorbing. It is widely used in various industrial sectors.
The expanded perlite fireproof board is a new type of fireproof door core filling material made of expanded perlite, pre-embedded skeleton, and a suitable adhesive as a binder.
The basic process overview is:
1. Material selection: Select the suitable expanded perlite material as the main material, select the applicable material as the skeleton, and select the binder that can meet the testing requirements as the bonding material.
2. Mixing: Add the binder to the perlite and stir it evenly through a special special mixer.
3. Pressurization: put the material into the mold or the core of the door core, pressurize,
4, the mold: the film, natural drying, packaging is the finished product.
Expanded perlite fireproof panels are currently divided into several different quality products:
