CSA expansive additive description: The CSA expansive additive is obtained by blending natural anhydrite with clinker powder which consists of calcium sulfoaluminate and CaO. This CSA expansive additive is always mixed with ordinary cement. When mixed in the proper proportion with ordinary cement and hydrated, cement mortar or concrete expands during the early stages of hydration. It is developed to reduce and compensate the hydraulic shrinkage of cement based construction expansive concrete. Its performance is similar to Denka CSA #20, which is now widely used in the formulation of different mortars in Europe countries.

TTA3150 poly [(2-ethylene epoxide) - 1 2 cyclohexane diol] 2-ethyl-2 - (hydroxymethyl) - 1,3-propylene glycol ether is a typical cycloaliphatic epoxy resin, which contains very little chloride ions and chloride salts. It has the characteristics of high transparency, high heat resistance, high Tg, excellent weather resistance, and excellent electrical properties (arc resistance and electric trace resistance). Its epoxy group at the end has similar reactivity with the epoxy group of polyether polyol glycidyl ether epoxy resin and can be cured with curing agents such as anhydride, phenol, amine, and cationic curing agent. It is widely used in composite materials, electrical insulation materials, electronic adhesives, powder coatings, and other fields.

The inner box material is made from a stainless steel plate with high-temperature resistance and anti-corrosion, which is made by argon-arc welding and sealing. Then make strong bone reinforcement, anti-bending and anti-deformation. The external structure was made from steel plate with powder coating process. It adopts advanced insulation cotton, the inner liner is directly heated, and the surface temperature of the machine is low. The high temperature resistant hot glue is tight, environmental protection and pollution-free, and the strong type of door buckle is adopted.
