The Use of EVA Powder and Cellulose in Dry Mortar

The Use of EVA Powder and Cellulose in Dry Mortar

Material definition:

Powdered thermoplastic resins made of polymer emulsion by spray drying and subsequent treatment

Main varieties:

1. vinyl acetate and ethylene copolymer powder (vac/e)
2. ethylene and vinyl chloride and lauric acid ethylene resin ternary copolymer gum powder (E/VC/VL)
3. vinyl acetate and ethylene and advanced fatty acid ethylene grease ternary copolymer gum powder (Vac/e/veova)

Feature use:

1. increase cohesion (film)
2. Increase cohesion (bonding)
3. increased flexibility (flexible)

Second, cellulose ether, dosage 0.03-1%, viscosity 300.4 million MPa.

Material definition:

The natural fiber is processed by alkali solution, graft reaction (etherification), washing, drying, grinding and so on.

Main varieties:

1. methyl hydroxyethyl cellulose ether (MC)
2. Methyl hydroxypropyl cellulose ether (MC)
3. Sodium Carboxymethyl Cellulose (CMC)

Feature use:

1. Water protection
2. thickening
3. improve the bond strength
4. Improve Construction performance

Third, starch ether, dosage 0.01-0.1%

Material definition:

It can affect the mortar consistency of gypsum/cement and lime, the construction of mortar and the resistance to flow

Main varieties:

Often used in conjunction with cellulose ether

Feature use:

1. thickening
2. Improve construction
3. Anti-flow hanging property
4. Skid resistance
