Pocymers polymers polymers (RDP) dị mgbagwoju anya agwakọta nke polymers na ihe mgbakwunye na-eji n'ọtụtụ ihe ndị a kpọrọ nkụ. Ikike ndị a na-arụ ọrụ dị mkpa na imezi arụmọrụ na njiri mara ihe dị iche iche dịka taịlị, ahịhịa na ciment na ciment.
Ihe ndị dị mkpa:
Polymer:
A na-ejikarị ọrịa acetate (Eva): A na-ejikarị Eva Cololis na RDP n'ihi ezigbo ihe akụrụngwa, adhesion, na mgbanwe. Vinyl acetate ọdịnaya nwere ike idozi ịgbanwe Njirimara nke polymer.
Vinyl acetate vs. ethylene carbonate: dabere na nkọwapụta nke ngwa ahụ, ndị na-emepụta nwere ike iji carbonate athonate kama vinyl acetate. Ethylene carbonate agbanweela nguzogide na adresion na iru mmiri.
Acrylics: Acrylic polymers, gụnyere acryyymers dị ọcha, na-eji ngwa ngwa, a na-eji ya maka nguzogide ihu igwe, ịdịte aka, na nke dị iche iche. A maara ha maka inye ezigbo ndọnye ụdị mkpụrụ dị iche iche.
Chebe colloid:
Hydroxypyl Methylcelllose (HPMC): HPMC bụ ihe nchebe na-ejikarị na RDP. Ọ na-eme ka redishions nke polymer na-eme ka ihe niile sie ike.
Mmanya polyvinyl (PVA bu nchịkwa ọzọ na-echebe nke na-ebuli na nkwụsi ike na mgbasa nke polymer. Ọ na-arụkwa ọrụ iji chịkwaa viscosity nke ntụ ntụ.
Plastizer:
Dibutyl phyalate (dbp): DBP bụ ọmụmaatụ nke plastizer na-etinyekarị na RDP iji meziwanye mgbanwe na nhazi ọrụ. Ọ na - enyere aka belata mmiri ntụgharị nke polymen, na - eme ka ọ na - agbanwe.
fillet:
Carbonate carbonate: fillent dị ka carbonate carbonate nwere ike tinye iji mee ka ọtụtụ ụzọ dị mma iji dozie ihe dị ka udidi na ndabara.
Na-ekwupụta na antioxidants:
Nkwụsị: A na-eji ihe ndị a iji gbochie mmebi nke polymer n'oge nchekwa na nhazi.
Antioxidants: antioxidant na-echebe polymer site na mmebi nke oxiditive, na-ejide ogologo oge nke RDP.
Ọrụ nke ngwa ọ bụla:
Polymer: na-enye akụrụngwa na-akpụ akpụ akpụ ihe nkiri, adhesion, na-agbanwe ma sie ike na ngwaahịa ikpeazụ.
Nchebe colloid: Kwalite mgbanwe, nkwụsi ike na mgbasa nke polymer.
Clanizer: na-eme ka mgbanwe na nhazi ọrụ.
Filter: Gụgharịa Njirimara dị ka udidi, na akụrụngwa, na ofa.
Kwụrụ na antioxidants: igbochi mmebi iwu polymer n'oge nchekwa na nhazi.
na ngwụcha:
Redisperssible polymer ntụ ntụ (RDP) bụ ihe dị iche iche ma dị mkpa na akụrụngwa ụlọ ọgbara ọhụrụ. Ihe mejupụtara kemịkal ya, gụnyere polymers dịka eva ma ọ bụ acrylic resins, collylic resins, colloids na-echebe, fọdụrụnụ, fillexans, ndị na-eme ka ha guzozie ihe ndị ọ bụla ngwa. Nchikota ndia na-enyere aka melite ntụzi ntụ ntụ, njikọ ike, ngbanwe na arụmọrụ dị na mpekere mmachi.
