Urukuta rwimbere ninyuma rushyiramo ifu, ifata tile, igikoresho cyerekana tile, icyuma cyumye cyumushanyarazi, minisiteri yumuriro wumuriro winkuta ziva hanze, minisiteri yo kwisuzumisha, minisiteri yo gusana, minisiteri ishushanya, minisiteri idafite amazi yo hanze yubushyuhe bwumuti wumye.
Muri minisiteri, ni ukunoza ubwitonzi, modulus yo hejuru ya elastike nizindi ntege nke za minisiteri gakondo ya sima, no guha sima ya sima hamwe nubworoherane bukomeye hamwe nimbaraga zingirakamaro, kugirango irwanye kandi itinde kubyara ibisekuru bya sima.Kubera ko polymer na minisiteri bigize imiyoboro ihuza imiyoboro, hakozwe firime ikomeza ya polymer mu byobo, bishimangira isano iri hagati ya agregate kandi igahagarika imyenge imwe muri minisiteri, bityo minisiteri yahinduwe nyuma yo gukomera iruta sima ya sima.Hariho iterambere ryinshi.
Uruhare rwa redispersible latex powder muri putty ni mubice bikurikira:
1. Kunoza imiterere hamwe nubukanishi bwa putty.Ifu ya Redispersible latex ni ifu yifu ikozwe muri emulsiyo idasanzwe (polymer polymer ndende) nyuma yo kumisha.Iyi poro irashobora guhinduka vuba muri emulsiyo nyuma yo guhura namazi, kandi ikagira ibintu bisa na emulioni yambere, ni ukuvuga ko ishobora gukora firime nyuma yuko amazi azimye.Iyi firime ifite ihindagurika ryinshi, irwanya ikirere kinini kandi irwanya uburyo butandukanye bwo gufatira hamwe na substrate.Byongeye kandi, ifu ya hydrophobique latex irashobora gukora minisiteri idafite amazi.
2. Kunoza ubumwe bwa putty, kurwanya cyane, kurwanya alkali, kwambara birwanya, no kongera imbaraga zidasanzwe.
3. Kunoza amazi adashobora gukoreshwa n'amazi ya putty.
4. Kunoza uburyo bwo gufata amazi ya putty, kongera igihe cyo gufungura, no kunoza imikorere.
5. Kunoza ingaruka zo guhangana na putty no kongera igihe kirekire.
2. Uruhare rwifu ya latx isubirwamo mumatafari ya tile ni mubice bikurikira:
1. Mugihe ingano ya sima yiyongera, imbaraga zumwimerere zifata tile ziriyongera.Muri icyo gihe, imbaraga zifatika nyuma yo kwibizwa mu mazi n'imbaraga zifatika nyuma yo gusaza ubushyuhe nazo ziriyongera.Umubare wa sima ugomba kuba hejuru ya 35%.
2. Hamwe no kwiyongera kwinshi kwifu ya latx isubirwamo, imbaraga zingirakamaro nyuma yo gushira mumazi nimbaraga zumubano wa tensile nyuma yo gusaza ubushyuhe bwumuti wa tile wiyongera bikwiranye, ariko imbaraga zubusabane nyuma yubusaza bwumuriro ziyongera cyane bigaragara.
3. Hamwe no kwiyongera kwa selile ya selile, imbaraga zifatika za tile zifata tile nyuma yubusaza bwumuriro ziriyongera, nimbaraga zifatika nyuma yo gushira mumazi ubanza kwiyongera hanyuma bikagabanuka.Ingaruka nibyiza mugihe selile ya ether iri hafi 0.3%.
Mugihe dukoresha ifu ya redxersible latex, dukwiye kwitondera ingano yimikoreshereze, kugirango ibashe kugira uruhare rwayo.
