Ntughari polymer na-acha uhie uhie (RDP)bụ ihe na-eme ka mmiri na-egbu egbu, nke a na-ejikarị na ihe dị ka ihe owuwu, mkpuchi, na tile adhesives. Ọrụ ya bụ imegharị amulsion n'ime emulsion site na itinye mmiri, na-enye ezigbo adhesion, na-agbanwe agbanwe, na nguzogide, na iguzogide ihu igwe.
Enwere ike ị nweta nyocha polmer polymerble (RDP) site na ọtụtụ akụkụ, tumadi gụnyere ihe ndị a:
1. Onye na-eme polymer resin
Ihe nchịkọta nke polymer na-acha uhie uhie bụ polymer resin, nke na-abụkarị polymen na-enweta site na polymerion. Polymen resins gụnyere:
Mmanya polyvinyl (PVA): nwere ezigbo adhesion na ihe ngosi ihe nkiri na-akpụ akpụ ma na-ejikwa ya na akụrụngwa.
Polyyacrylites (dịka polyacryrylates, polyurethanes, wdg): Nwee ike dị mma, ike na-egbochi ya.
Polystyrene (ps) ma ọ bụ nke etylene-vinyl acetate conolymer (Eva): na-ejikarị eme ka ihe ndị na-akpụ akpụ ihe nkiri na-emepụta ihe nkiri, na-abawanye nguzogide, na iguzogide mmiri.
Polyythyl metrylrylate (PMMMMA): Onye polymer a nwere ezigbo mgbochi na nghọta.
A na-enweta polymer ndị a site na mmeghachi omume nke polymerization, mgbe ahụ, a na-ewepụta mmiri a emulsion ma ọ bụ ihicha polmerble polmerble (RDP) n'ụdị ntụ ntụ.
2. Surfractants
Iji nọgide na nkwụsi ike n'etiti ụmụ irighiri polymer ma zere agglomeration na ntụ ntụ, a ga-agbakwunye ego nke sustoracts n'oge usoro mmepụta. Ọrụ nke Surrectants bụ iji belata esemokwu dị n'etiti ụmụ irighiri mmiri ma nyere aka na-agbasa na mmiri. Ndị nkịtị na-ahụkarị gụnyere:
Ndị na-abụghị nke Ionic Surractants (dịka polyethers, polyethylene glycols, wdg).
Anionic Surractants (dika mmanu abuba abuba, alkl sulfonates, wdg).
Ndị a na-asa ahụ nwere ike ịkwalite mgbasa polbilication polmerble polymer na-acha uhie uhie (RDP) s, na-ekwe ka mmiri si-mepụta emulsion mgbe ịgbakwunye mmiri.
3. Ndị filter na ndị dị omimi
Iji gbanwee arụmọrụ nke ngwa ngwụrọ ma belata ụgwọ, enwere ike ịgbakwunye filter na ndị ọzọ. E nwere ọtụtụ ụdị ndị jupụtara, ndị nkịtị gụnyere:
Carbonate carbonate: Mpempe akwụkwọ nke ahịhịa na-ejikarị nke nwere ike iwepụta nghazi ma melite arụmọrụ.
Talc: nwere ike ime ka mmiri ahụ dị na ndagide nke ihe ahụ.
Mization mineral: dị ka bennite, gbasaa eserese, wdg, nwere ike ịkwalite nguzogide na nguzogide nke ihe ahụ.
A na-ejikarị viscosity nke ngwaahịa a iji mee ka ọ dịgide n'ọnọdụ owuwu dị iche iche. Teska nkịtị gụnyere hydropyylthylthylthyl methylcellose (hpmc) na mmanya polyvinyl (PVA).
4. Onye na-eme nganga
Na ngwaahịa ntụ ntụ, iji gbochie agglomeration n'oge nchekwa na ụgbọ njem, enwere ike ịgbakwunye ndị na-eme ihe n'oge mmepụta. Ndị nnọchi anya na-egbu egbu dị mma, dị ka usoro ọkaibe, dị ka aluminom siyo, silinin dionide nwere ike ịpụta ihe nkiri na-eme ka ọ na-egbochi irighiri ihe ọnụ.
5. Ihe ndị ọzọ
Ntughari polymer na-acha odo odo (RDP) nwekwara ike ịnwe ụfọdụ ihe mgbakwunye pụrụ iche iji meziwanye ihe ndị akọwapụtara:
Onye ọrụ UV-na-eguzogide na-ahụ maka ihu igwe na-eguzogide na ike ịka nká.
Ihe mgbochi nje: na-ebelata uto nke microorganisms, ọkachasị mgbe ejiri ya na gburugburu iru mmiri.
Plastizer: Me ka mgbanwe na ndagide na-eguzogide nke mbubreyo.
Antiforhuze: egbochi ihe site na kefriza na gburugburu okpomoku, na-emetụta iwu na nsonaazụ.
6. Mmiri
Ọ bụ ezie na ntụ ntụ polymerble polymerble (RDP) dị n'ụdị akọrọ, ọ chọkwara ohere nchịkwa mmiri n'oge usoro ọgwụgwọ, a na-achịkwa ọdịnaya mmiri dị n'okpuru 1%. Ihe ala mmiri kwesịrị ekwesị na-enyere aka na-enyere aka ịnọgide na-enwe mmiri mmiri na ogologo oge nke ntụ ntụ.
Ọrụ na arụmọrụ nke polymer na-acha uhie uhie (RDP)
Ọrụ dị mkpa nke RedistPers polymerble polymer ntụ (RDP) bụ na enwere ike ịgbanye emulsion mgbe ị gbakwunye mmiri, ma nwee njirimara arụmọrụ ndị a dị mkpa:
Ezigbo adhesion: Kwalite ikike nke mkpuchi na adresives, ma meziwanye ike nke njikọta n'etiti ụlọ.
Na-agbanwe agbanwe na ngbanwe: Meziwanye mgbanwe nke mkpuchi, mee ka ọ gbagide na-eguzogide na nrụgide.
Nguzogide mmiri: Mee ka mmiri guzogide ihe ahụ, adabara iji ya ma ọ bụ iru mmiri.
Nguzogide ihu igwe: Meziwanye nguzogide UV, mgbochi ịka nká na ihe ndị ọzọ, wee gbasaa ndụ ọrụ ya.
Mgbade na-eguzogide: Ọ nwere ezigbo ndagide na kwesịrị ekwesị maka mkpa ịgbagọ mkpa na ọrụ owuwu.
Rdana-eme site na ịmegharị polymer emullion n'ime ntụ ntụ site na usoro ọkaibe. O nwere ọtụtụ ihe dị mma ma dị mma ma na-ejikarị ya arụ ọrụ, mkpuchi, adhesives na ubi ndị ọzọ. Nhọrọ na ngwakọta nke ihe ya metụtara arụmọrụ ikpeazụ ya.
