Redispersible Latex Powder (RDP) nibikoresho byingenzi byubaka kandi bikoreshwa cyane mubikoresho byubaka, ibikoresho byurukuta, ibikoresho byo hasi hamwe nindi mirima. Ihinduka ryiza cyane, gufatana hamwe no guhinduka biha inyungu zingenzi mugihe cyubwubatsi.
1. Gutegura emulisiyo
Intambwe yambere mugukora redispersible latex ifu nugutegura emulion. Mubisanzwe bikorwa na emulsion polymerisation. Emulsion polymerisation ni sisitemu yicyiciro cyamazi ikorwa ikwirakwiza kimwe monomers, emulisiferi, abatangiza nibindi bikoresho bibisi mumazi. Mugihe cya polymerisiyonike, monomers polymerize mubikorwa byabashinzwe gutangiza iminyururu ya polymer, bityo bikabyara emulisiyo ihamye.
Bikunze gukoreshwa na monomers kuri emulion polymerisation harimo Ethylene, acrylates, styrene, nibindi. Ukurikije imitungo isabwa, monomers zitandukanye zirashobora gutoranywa kuri copolymerisation. Kurugero, emulioni ya Ethylene-vinyl acetate copolymer (EVA) ikoreshwa cyane mugutegura ifu ya latxersible redxersible bitewe namazi meza yo guhangana n’amazi.
2. Shira kumisha
Nyuma ya emulsion imaze gutegurwa, igomba guhinduka ifu ya redispersible latex. Iyi ntambwe mubisanzwe igerwaho hifashishijwe tekinoroji yo kumisha. Gusasira kumisha nuburyo bwo kumisha bihindura vuba ibikoresho byamazi mubifu.
Mugihe cyo kumisha spray, emulion iba atomike mumatonyanga meza binyuze mumutwe hanyuma igahuzwa numwuka ushushe cyane. Amazi yo mu bitonyanga ahita ashira vuba, kandi ibintu bisigaye bihinduka uduce duto twa poro. Urufunguzo rwo gutera akuma ni ukugenzura ubushyuhe bwumwanya nigihe kugirango tumenye ubunini buke bwifu ya latex no gukama bihagije, mugihe wirinze kwangirika kwubushyuhe buterwa nubushyuhe bwinshi.
3. Kuvura hejuru
Kugirango tunoze imikorere nogukomera kwifu ya latx isubirwamo, ubuso bwayo buravurwa. Intego nyamukuru yo kuvura hejuru ni ukongera amazi ya poro, kunoza ububiko bwayo no kongera ubushobozi bwayo mumazi.
Uburyo busanzwe bwo kuvura hejuru burimo kongeramo imiti igabanya ubukana, imiti yo gutwika hamwe na surfactants. Imiti igabanya ubukana irashobora kubuza ifu guteka mugihe cyo kubika no gukomeza amazi meza; Ibikoresho byo gutwikisha mubisanzwe bifashisha polymers zishonga mumazi kugirango batwikire ifu ya latex kugirango birinde kwinjiza amazi; kongeramo surfactants birashobora Kunoza uburyo bwo guhinduranya ifu ya latex kugirango ishobore kwihuta kandi iringaniye nyuma yo kongeramo amazi.
4. Gupakira no kubika
Intambwe yanyuma mubikorwa byo kubyara ifu ya latx isubirwamo ni gupakira no kubika. Kugirango hamenyekane ubuziranenge n'imikorere y'ibicuruzwa, hagomba kwitonderwa gukumira ubushuhe, umwanda n'umukungugu biguruka mugihe cyo gupakira. Ubusanzwe ifu ya latx isubirwamo ipakirwa mumifuka yimpapuro nyinshi cyangwa imifuka ya pulasitike irwanya ubushuhe bwiza, hanyuma desiccant igashyirwa mumufuka kugirango wirinde ubushuhe.
Iyo ubitse, ifu ya redxersible powderx igomba gushyirwa ahantu humye, hahumeka, kure yizuba ryinshi nubushyuhe bwo hejuru, kugirango wirinde ifu cyangwa imikorere idahwitse.
Igikorwa cyo kubyaza umusaruro ifu ya latx isubirwamo ikubiyemo intambwe nyinshi nko gutegura emulsiyo, kumisha spray, kuvura hejuru, gupakira no kubika. Mugucunga neza ibipimo ngenderwaho bya buri murongo, ifu ya redxersible latex ifite imikorere myiza nubuziranenge buhamye irashobora kubyazwa umusaruro ukenewe mubikorwa byinganda zubaka. Hamwe nogukomeza gutera imbere kwikoranabuhanga, gahunda yo gutegura ifu ya redxersible powderx izarushaho kwangiza ibidukikije no gukora neza mugihe kizaza, kandi imikorere yibicuruzwa nayo izarushaho kunozwa.
