Ingaruka yifu ya latx isubirwamo kumiterere yifu ya putty

Kubyerekeye ikibazo ko ifu ya putty yoroshye kuyifu, cyangwa imbaraga ntabwo zihagije.Nkuko twese tubizi, ether ya selile ikeneye kongerwamo kugirango ikore ifu yuzuye, HPMC ikoreshwa mugushiraho urukuta, kandi abayikoresha benshi ntibongeramo ifu ya redxersible.Abantu benshi ntibongeramo ifu ya polymer kugirango babike ikiguzi, ariko iyi nayo ni urufunguzo rwimpamvu isanzwe isanzwe yoroshye ifu kandi ikunda guhura nibibazo byubuziranenge bwibicuruzwa!

Ibisanzwe bisanzwe (nka 821 putty) bikozwe cyane cyane nifu yera, kole nkeya ya krahisi na CMC (hydroxymethyl selulose), kandi bimwe bikozwe muri methyl selulose na poro ya Shuangfei.Iyi putty ntabwo ifata kandi ntabwo irwanya amazi.

Cellulose irashobora gukuramo amazi no kubyimba nyuma yo gushonga mumazi.Ibicuruzwa biva mu nganda zitandukanye bifite igipimo cyinshi cyo kwinjiza amazi.Cellulose igira uruhare mukubika amazi muri putty.Igishishwa cyumye gifite imbaraga zigihe gito gusa, kandi kizagenda gahoro gahoro nyuma yigihe kinini.Ibi bifitanye isano ya hafi na molekulire ya selile ubwayo.Ibishishwa nkibi birarekuye, bifite amazi menshi, byoroshye guhungabana, nta mbaraga bifite, kandi nta na elastique.Niba ikoti ryashyizwe hejuru, PVC yo hasi iroroshye guturika no kubira ifuro;PVC ndende iroroshye kugabanuka no kumeneka;kubera kwinjiza amazi menshi, bizagira ingaruka kumiterere ya firime n'ingaruka zo kubaka topcoat.

Niba ushaka kunoza ibibazo byavuzwe haruguru bya putty, urashobora guhindura formulaire ya putty, ukongeramo ifu ya redxersible latex muburyo bukwiye kugirango utezimbere imbaraga za nyuma, hanyuma uhitemo hydroxypropyl methylcellulose HPMC ifite ireme ryiza.

Muburyo bwo kubyara umusaruro, niba ingano yifu ya redxersible latex yongeweho idahagije, cyangwa niba ifu ya latx yo hasi ya putty ikoreshwa, bizagira izihe ngaruka kuri poro ya putty?

Umubare udahagije wa putty redispersible latex powder, ikigaragara cyane ni uko igipande cya putty kirekuye, ubuso burahinduka, ubwinshi bwirangi ryakoreshejwe mukwambika hejuru ni binini, imitungo iringaniye irakennye, ubuso burakomeye nyuma yo gukora firime, kandi biragoye gukora firime yuzuye irangi.Inkuta nkizo zikunda gukonjeshwa, kubyimba, gukuramo, no gucamo firime.Niba uhisemo ifu ntoya, biragaragara ko imyuka yangiza nka formaldehyde ikorerwa kurukuta bizatera abandi nabi umubiri.
