Kedu ihe bụ ntụ ntụ Polymer Redispersible?

Redispersible polymer ntụ ntụ (RDP) bụ ụdị polymer ntụ ntụ nwere ike redispersed na mmiri na-etolite a kwụsiri ike dispersion ma ọ bụ emulsion. Ọ bụ ntụ ntụ akọrọ nke a na-emepụta site na ịgbasa-ihicha emulsion polymer. A na-eji RDP mee ihe n'ụdị dị iche iche, gụnyere ihe owuwu, ihe mkpuchi, mkpuchi na mkpuchi.

RDP bụ ụdị polymers dị iche iche, dị ka acrylics, polyvinyl acetate (PVA), mmanya polyvinyl (PVOH), na styrene-butadiene (SBR). A na-ejikọtakarị polymers ọnụ iji mepụta ntụ ntụ nwere ihe ndị a chọrọ. A na-efesa ntụ ntụ ahụ ka ọ bụrụ ntụ ntụ. Enwere ike ịgbasa ntụ ntụ n'ime mmiri iji mepụta mgbasa ma ọ bụ emulsion kwụsiri ike.

A na-eji RDP mee ihe n'ụdị dị iche iche, gụnyere ihe owuwu, ihe mkpuchi, mkpuchi na mkpuchi. N'ime ihe owuwu, a na-eji RDP mee ihe dị ka ihe mgbakwunye na ụrọ na plasta dabeere na ciment. Ọ na-eme ka arụ ọrụ, nrapanye, na nguzogide mmiri nke ngwa agha ma ọ bụ plasta dịkwuo mma. Na adhesives, a na-eji RDP emeziwanye ihe nkedo nke nrapado na mkpụrụ. Na mkpuchi, a na-eji RDP mee ka mmiri na-eguzogide mmiri na mgbanwe nke mkpuchi. Na sealants, a na-eji RDP eme ka adhesion na mgbanwe nke ihe mkpuchi.

A na-ejikwa RDP na ngwa ndị ọzọ dị iche iche, dị ka mkpuchi akwụkwọ, mkpuchi akpụkpọ anụ, na akwa akwa. Na mkpuchi akwụkwọ, a na-eji RDP mee ka mmiri na-eguzogide mmiri na ike nke akwụkwọ ahụ. Na mkpuchi akpụkpọ anụ, a na-eji RDP mee ka mmiri na-eguzogide mmiri na mgbanwe nke akpụkpọ anụ. Na mkpuchi akwa akwa, a na-eji RDP mee ka mmiri na-eguzogide mmiri na mgbanwe nke ákwà ahụ.

RDP bụ ihe dị iche iche nke a na-eji na ngwa dị iche iche. Ọ bụ ntụ ntụ akọrọ nke enwere ike ịgbasa n'ime mmiri iji mepụta mgbasa ma ọ bụ emulsion kwụsiri ike. A na-eji RDP eme ihe n'ịrụ ụlọ, ihe mkpuchi, mkpuchi, na ihe mkpuchi iji melite arụmọrụ, nkwụsịtụ, na nkwụsị mmiri nke ngwaahịa. A na-ejikwa RDP na ngwa ndị ọzọ dị iche iche, dịka mkpuchi akwụkwọ, mkpuchi akpụkpọ anụ, na akwa akwa.
