I-Redisperible Powmer Powder (RDP) iyi-copolymer ye-vinyl acetate ne-ethylene ekhiqizwa ngenqubo yokuchomisa yokufafaza. Kuyisithako esiyisihluthulelo ezinhlelweni ezahlukahlukene zokwakha, ukuhlinzeka ngokunamathelisa okungcono, ukuguquguquka nokuqina kwemikhiqizo esekwe kuthusi. Ukwenziwa kwe-PolyPressible Powmer Powders kubandakanya izinyathelo eziningana.
1. Ukukhethwa kwezinto ezibonakalayo:
I-Vinyl Acetate-Ethylene Copolymer: Izinto eziphambili ezingavuthiwe ze-RDP ziyi-copolymer ye-vinyl acetate ne-ethylene. Le copolymer yakhethwa ngezakhiwo zayo ezinhle kakhulu zokunamathela kanye nekhono lokukhulisa ukuguquguquka nokuqina kwezinto zokwakha cementize.
2. Emulsion polymerization:
Inqubo yokukhiqiza iqala nge-emulsion polymerization, lapho i-vinyl acetate kanye nama-ethylene monomes ane-polymer
Inqubo ye-emulsion polymerization ilawulwa ngokucophelela ukuthola isisindo samangqamuzana, ukwakheka, nesakhiwo se-copolymer.
3. Ukuphendula kanye noCopolymerization:
Ama-vinyl acetate kanye nama-ethylene monomers asabela phambi kwe-catalyst ukwakha i-copolymer.
Inqubo ye-Copolymerization ibalulekile ukuthola ama-polymers ngezakhiwo ezifiselekayo, kufaka phakathi izakhiwo ezinhle zefilimu kanye nokubuyiselwa kabusha.
4. Spray COMSE:
I-emulsion bese ifakwa kwinqubo yokuchomisa yokufafaza. Lokhu kufaka ukufafaza i-emulsion kugumbi elishisayo, lapho amanzi avele khona, eshiya ngemuva kwezinhlayiya eziqinile ze-polymer evuselelayo.
Izimo zokuchofoza zokufafaza, njengokushisa nokushisa komoya, zilawulwa ngokucophelela ukuze kuqinisekiswe ukwakheka kwezinhlayiya ezinhle ze-Fine Powder.
5. Ukwelashwa okungaphezulu:
Ukwelashwa okungaphezulu kuvame ukusetshenziselwa ukuthuthukisa ukuqina kwesitoreji kanye nokuvuselelwa kabusha kwama-polymer powders.
Izithasiselo ze-Hydrophobic noma ama-colloids avikelayo avame ukusetshenziswa ekwelashweni komhlaba ukuvikela izinhlayiyana ze-agglomeration futhi athuthukise ukuhlakazeka kwempuphu emanzini.
6. Ukulawulwa kwekhwalithi:
Izindlela eziqinile zokulawula ikhwalithi zisetshenziswa kuyo yonke inqubo yokwenza. Amapharamitha anjengokusatshalaliswa kosayizi wezinhlayiyana, ukuhlukaniswa ngobuningi, okuqukethwe okuseleyo kwe-monomer kanye nokushisa kwengilazi kubhekwa ukuqinisekisa ukungaguquguquki komkhiqizo.
7. Ukupakishwa:
I-polymer powder yokugcina ye-polymer ifakwe ezitsheni zobufakazi bokuma umswakama ukuvikela ukumuncwa kwamanzi, okungathinta kabi ukusebenza kwawo.
Izicelo ze-PolyMer Po powders:
I-RDP isetshenziswa ezinhlobonhlobo zokwakha kufaka phakathi ukunamathela kwe-tile, amakhompiyutha okuzimela, amasistimu wokuqedwa kokufakwa kwangaphandle (ama-EIFs) kanye no-mathupha.
I-powder ithuthukisa izakhiwo ezinjengokumelana namanzi, ukuguquguquka kanye nokunamathela, kusiza ukuthuthukisa ukusebenza okuphelele nokuqina kwalezi zinto zokwakha.
Ekuphetheni:
I-Redisperservible Pelmer Powder iyinto eguquguqukayo enezicelo ezibalulekile embonini yezokwakha. Ukukhiqizwa kwalo kufaka ukukhetha ngokucophelela kwezinto zokusetshenziswa okuluhlaza, i-emulsion polymerization, ukomisa okufafaza, ukwelashwa okungaphezulu nezindlela eziqinile zokulawula ikhwalithi.
Ukwenziwa kwe-Permensible Poly Minder kuyinqubo eyinkimbinkimbi edinga ukunemba nokunaka imininingwane yokuthola umkhiqizo osezingeni eliphakeme ngezakhiwo ezidingekayo kwizicelo zokwakha.
