Nibihe bintu bya minisiteri bishobora kunozwa nifu ya redxersible powder?

Ifu ya redispersible latex ikozwe muri emulioni ya polymer mukumisha spray, ikavangwa namazi mumabuye ya sima, emulisile ikwirakwizwa mumazi, hanyuma ikabyara polymer ihamye. Nyuma yifu ya pisitori ya latx isubirwamo kandi ikwirakwizwa mumazi, amazi arahumuka, Kora firime ya polymer mumabuye kugirango utezimbere imitungo ya minisiteri. Ifu itandukanye isubirwamo ifu ya latx igira ingaruka zitandukanye kumashanyarazi yumye.

1. Kunoza ingaruka zo guhangana ningaruka, imikorere no kwambara minisiteri

Minisiteri yuzuyemo ciment mortar pore cavite, ubwuzuzanye bwa sima ya sima iratera imbere, kandi kurwanya imyambarire biratera imbere. Mubikorwa byimbaraga zo hanze, birashobora gutera kuruhuka bitarimbuwe. Impapuro za polymer zirashobora kubikwa muri sisitemu yo gucunga sima.

2. Kunoza ifatizo ryubwubatsi bwa minisiteri

Ifu ya polymer yamashanyarazi igira ingaruka zo guhanagura, kuburyo ibice bibiri bigize sima ya sima ishobora gutembera yigenga. Byongeye kandi, ifu ya reberi igira ingaruka zo gutera gaze.

3. Kunoza imbaraga zo guhuza imbaraga nimbaraga zifatika za minisiteri

Nka miti kama ifata imiti, ifu ya latx isubirwamo irashobora kubyara imbaraga zo gukomeretsa nimbaraga zo kwikuramo ku mbaho ​​zitandukanye. Ifite uruhare runini muguhuza sima ya sima nibikoresho ngengabuzima bya chimique (igifu, ikibaho gikingira ifuro) hamwe nubuso bwikibaho. DEM ibikoresho fatizo hamwe nifu ya polymer yangiza bikoreshwa cyane muri sisitemu zose zo gucunga sima kugirango zongere ubumwe bwa sima.

4.

Ifu ya redispersible latex ni resimoplastique resin ifite imiterere ihindagurika, ishobora gutuma minisiteri yangiza ibyangijwe nubushyuhe bwo hanze hamwe nubukonje bukabije, kandi birinda kwirinda gucikamo ibice kubera ihindagurika ryubushyuhe.

5. Kongera hydrophobicity ya minisiteri no kugabanya ibirimo ubuhehere

Ifu ya redispersible latex yamanuwe mumasima ya sima na sima, kandi impapuro za polymer ntabwo byoroshye guhinduka nyuma yo gutunganya amazi, kubuza kwinjira mumazi no kunoza ubudahangarwa. Ubu bwoya bwangiza amazi yubwoya bufite ingaruka nziza kubera ubushobozi budasanzwe bwo gukwirakwiza ifu ya latx naturel.

Porogaramu nyamukuru ya redispersible latex powder

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.

Ibicuruzwa bya redispersible latex powder

1. Kunoza imbaraga zigoramye nimbaraga zoroshye za minisiteri

Filime ya polymer yakozwe na redispersible latex ifu ifite ihinduka ryiza. Filime zakozwe mu cyuho no hejuru ya sima ya minisiteri kugirango ibe ihuza byoroshye. Amabuye ya sima aremereye kandi yoroheje ahinduka byoroshye. Mortar yongewemo nifu ya redxersible powderx irikubye inshuro nyinshi murwego rwo guhangana na flexural kurusha minisiteri isanzwe.

2. Kunoza imbaraga zo guhuza hamwe no guhuza minisiteri

Nyuma yifu ya redxersible latex ifumbire mvaruganda ikozwe muri firime, irashobora gukora imbaraga zingirakamaro hamwe nimbaraga zo guhuza ibice bitandukanye. Ifite uruhare runini muguhuza minisiteri ibikoresho kama (EPS, ikibaho cya furo) hamwe nubutaka bworoshye. Ifu ikora polymer reberi ikwirakwizwa muri sisitemu ya minisiteri nkibikoresho bishimangira kongera ubumwe bwa minisiteri.

3. Kunoza ingaruka zo guhangana ningaruka, kuramba no kwambara minisiteri

Ibice by'ifu ya reberi byuzuza umwobo wa minisiteri, ubwinshi bwa minisiteri bwiyongera, kandi birwanya kwambara. Mubikorwa byimbaraga zo hanze, bizabyara kuruhuka bitarimbuwe. Filime ya polymer irashobora kuboneka burundu muri sisitemu ya minisiteri.

Ifu ya redispersible latex ni resmoplastique resin ifite imiterere ihindagurika, ishobora gutuma minisiteri ihangana n’imihindagurikire y’ibidukikije bikonje kandi bishyushye, kandi bikarinda neza ko minisiteri itavunika kubera ihinduka ry’ubushyuhe.

5. Kunoza hydrophobicity ya minisiteri no kugabanya kwinjiza amazi

Ifu ya redispersible latex ikora firime hejuru yu mwobo no hejuru yubutaka bwa minisiteri, kandi firime ya polymer ntizongera gutatana nyuma yo guhura n’amazi, ikabuza kwinjira mu mazi kandi ikanatezimbere. Ifu idasanzwe ya redxersible latex ifu ya hydrophobique, ingaruka nziza ya hydrophobique.

6. Kunoza imikorere yubwubatsi bwa minisiteri

Hariho amavuta yo kwisiga hagati ya polymer rubber yamashanyarazi, kugirango ibice bya minisiteri bishobore kugenda byigenga. Muri icyo gihe, ifu ya reberi igira ingaruka zidasanzwe mu kirere, igaha minisiteri kandi igateza imbere ubwubatsi bwa minisiteri.
