Resin powder. It is a white powder with good fluidity, which is mixed with high molecular polymer resin, ultra-fine load anticoagulant and various functional additives.
First, the nature is different.
1. Resin powder. It is a white powder with good fluidity, which is mixed with high molecular polymer resin, ultra-fine load anticoagulant and various functional additives.
2. Redispersible polymer powder. Redispersible latex powder is a copolymer of ethylene and vinyl acetate, which is divided into ethylene/vinyl acetate copolymer, vinyl acetate/tertiary vinyl carbonate copolymer, acrylic copolymer, etc.
The powder adhesive made by spray drying adopts polyvinyl alcohol as protective colloid. This powdery rubber powder can quickly disperse into an emulsion upon contact with water, because the dispersible polymer powder has a high binding capacity and unique properties.
Second, the functions are different.
1. Resin powder. It is used in the external wall insulation industry to replace the traditional latex powder with high cost and high addition amount.
2. Redispersible polymer powder.
The main results are as follows: 1. The redispersible latex powder can be dispersed to form a film, which can enhance the second adhesive. The protective colloid is absorbed by the mortar system (after film formation is not destroyed by water, or "secondary dispersion"). 3. The polymer resin formed by film formation is distributed in the entire mortar system as a reinforcing material, thereby increasing the cohesion of the mortar.
Third, the application fields are different.
1. Resin powder
It is used in the field of external wall thermal insulation products (foamed polystyrene board thin plaster external wall external thermal insulation system). 1). Special rubber powder for extrusion board system. 2). Special rubber powder for polystyrene board system. 3). Special rubber powder for polystyrene particle thermal insulation mortar. 4). Special glue powder for exterior wall putty. 5). Special adhesive powder for tile bonding. 6). Special rubber powder for vitrified bead insulation mortar. 7). Special powder for waterproof mortar. 8). Special rubber powder for perlite thermal insulation mortar.
2. Dispersible polymer powder 1). Tile adhesive. 2). The mortar is bonded by the external insulation system of the external wall. 3). Plastering mortar for external thermal insulation system. 4). Tile sealant. 5). Self-flowing cement mortar. 6). Flexible putty for interior and exterior walls. 7). Flexible crack resistant mortar. 8). Rubber powder polystyrene particle insulation mortar. 9). Dry powder coating. 10). Polymer mortar products that require high flexibility.
