Application of rubber powder and cellulose in dry powder mortar

Rubber powderUse of cellulose in dry mortar
1. redispersible latex powder (EVA), dosage 1-5%
Material Definition:
High molecular polymer emulsion by spray drying, and subsequent processing of powder thermoplastic resin
Main varieties:
1. Vinyl acetate and ethylene copolymer rubber powder (VAC/E)
2. Ethylene, vinyl chloride and lauric acid ethylene ester ternary copolymer rubber powder (E/VC/VL)
3. Vinyl acetate and ethylene and higher fatty acid ethylene copolymer powder (VAC/E/VeoVa)
Characteristic use:
1. Increase cohesion (film formation)
2. Increase cohesion (bonding)
Increased flexibility (flexibility)
2. cellulose ether, content 0.03-1%, viscosity 300-400000 Mpa.s
Material Definition:
The use of natural fibers by alkali solution, grafting reaction (etherification), washing, drying, grinding and other processes
Main varieties:
1. Methyl hydroxyethyl cellulose ether (MC)
2. Methyl hydroxypropyl cellulose ether (MC)
3. Sodium carboxymethyl cellulose (CMC)
Characteristic use:
1. Water retention
2. Thickening
3, improve the bond strength
4. Improve construction performance
3. starch ether, 0.01-0.1%
Material Definition:
Can affect the consistency of mortar based on gypsum/cement and lime/change the workability and sag resistance of mortar
Main varieties:
Often used in conjunction with cellulose ethers
Characteristic use:
1. Thickening
2, improve the construction
3. Anti-sagging
4. Slip resistance
