Gusobanukirwa byimazeyo ifu ya polymer ikwirakwizwa (VAE) ningaruka zayo kuri minisiteri yumye
Ifu ya redispersible latex ikozwe muri polymer emulsion ukoresheje spray yumye. Ivangwa namazi muri sima ya sima, emulisile kandi ikwirakwizwa mumazi, hanyuma ikabyara polymer ihamye. Ifu ya reberi imaze kwigana no gukwirakwizwa mu mazi, amazi arahumuka. Filime ya polymer ikorwa imbere kugirango itezimbere imiterere ya minisiteri. Amafu atandukanye ya redxersible latex afite ingaruka zitandukanye kumashanyarazi yumye.
Nibihe bintu bya minisiteri bishobora kunozwa nifu ya redxersible powder?
1. Kunoza ingaruka zo kurwanya, 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 guhuza imbaraga zo guhuza imbaraga hamwe 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. Ifu ya reberi ikoreshwa cyane muri sisitemu zose zo gucunga sima kugirango zongere ubumwe bwa sima.
4. Kunoza gusaza kwa minisiteri, kurwanya inzitizi zogukonjesha, no kwirinda sima ya sima.
Ifu ya reberi nubushyuhe bwa termoplastique hamwe nubworoherane bwiza, bushobora gutuma minisiteri ikora ibyangiritse byatewe n’ibidukikije bishyushye n’ubukonje, kandi mu buryo bwumvikana birinda gucika muri minisiteri bitewe n’imihindagurikire y’ubushyuhe.
5. Ongera hydrophobicity ya minisiteri kandi ugabanye ubuhehere
Ifu ya reberi isenyuka mu cyuho cya sima no hejuru y’ubutaka, kandi impapuro za polymer ntizoroshye kongera gutunganywa nyuma yo gutunganya amazi, kubuza kwinjira mu mazi no kunoza ubudahangarwa.
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.
Imikorere yibicuruzwa bya redxersible powderx:
1. Kunoza imbaraga zunamye n'imbaraga zoroshye za minisiteri
Filime ya polymer yakozwe na Zhaojia redispersible powder ifu ifite ihinduka ryiza. Filime zakozwe mubyuho no hejuru yubutaka bwa sima ya minisiteri kugirango ihuze byoroshye. Amabuye ya sima aremereye kandi yoroheje ahinduka byoroshye. Mortar yongeyeho ifu ya redxersible powderx irikubye inshuro nyinshi murwego rwo guhangana na flexural kurusha minisiteri isanzwe.
2. Kunoza imbaraga zo guhuza hamwe no guhuriza hamwe
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, 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.
4. Kunoza uburyo bwo guhangana nikirere no kurwanya ubukonje bwa minisiteri, kandi ukarinda minisiteri guturika
Ifu ya reberi nigikoresho cya termoplastique gifite imiterere ihindagurika, gishobora gutuma minisiteri ishobora guhangana n’imihindagurikire y’ibidukikije bikonje kandi bishyushye, kandi bikarinda neza minisiteri guturika bitewe n’imihindagurikire y’ubushyuhe.
5. Kunoza hydrophobicity ya minisiteri no kugabanya kwinjiza amazi
Ifu ya latex ikora firime kumurongo wa minisiteri no hejuru, kandi firime ya polymer ntizongera gutatana nyuma yo guhura namazi, ikabuza kwinjira mumazi 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.
