Redispersible latex Powder (RDP) nigicuruzwa gihindura polymer emulioni yifu yubusa-yifashishije ikoranabuhanga ryumye. Iyo ifu ivanze namazi, yongeye gukora latex kandi ifite imitungo isa na emulion yumwimerere. Bitewe nibi bintu bidasanzwe biranga, ifu ya latx isubirwamo yakoreshejwe cyane mubikoresho byubwubatsi, ibifatika, ibifuniko nizindi mirima.
1. Ibyiza bya redispersible powderx
Kunoza imikorere yibicuruzwa Redispersible latex ifu irashobora kuzamura cyane imbaraga zingutu, imbaraga zidasanzwe hamwe nimbaraga zo guhuza ibikoresho bishingiye kuri sima. Ibi biterwa nuko ifu ya latex irashobora gukora firime ikomeza ya polymer mugihe cyo gutunganya sima, ikongerera ubwinshi nubukomezi bwibikoresho, bityo bikazamura imikorere muri rusange. Kurugero, mugufata tile, kongeramo ifu ya latex irashobora kunoza imbaraga zayo kandi ikarinda amabati kugwa.
Kongera imbaraga zo kurwanya no kutemerwa Mubikoresho byubwubatsi, kurwanya gukomeretsa no kudahinduka ni ibintu byingenzi byerekana imikorere. Ifu ya redispersible latex irashobora kuzuza neza imyenge ya capillary yibikoresho mugukora firime ya polymer, kugabanya amazi yinjira no kunanirwa. Muri icyo gihe, ubworoherane bwa firime ya polymer burashobora kandi gutinda cyangwa kubuza iterambere rya microcrack, bityo bikarwanya guhangana. Kubwibyo, ifu ya latex ikoreshwa cyane muri sisitemu yo hanze yinkuta hamwe nibikoresho byo hasi.
Kunoza imikorere yubwubatsi: Kubera ko ifu ya redxersible latex ifite isubiranamo ryiza kandi ikomatanya, irashobora kunoza amavuta nogukora ibikoresho byubwubatsi mugihe cyubwubatsi, bigatuma ibikoresho byoroha gukwirakwizwa no gukoreshwa. Byongeye kandi, ifu ya latex irashobora kandi kongera igihe cyo gufungura ibikoresho (nukuvuga, igihe ibikoresho bikomeza gukoreshwa mugihe cyubwubatsi), kunoza imikorere yubwubatsi, no kugabanya imyanda yibikoresho.
Kuramba kuramba Filime ya polymer yakozwe kuva ifu ya redispersible latex ifasha gusaza no guhangana nikirere. Irashobora gukumira neza ingaruka z'imirasire ya ultraviolet, aside na alkali kwangirika hamwe nibindi bidukikije, bityo bikongerera igihe cyo gukora cyibikoresho. Kurugero, kongeramo ifu ya latex kumarangi yurukuta rwinyuma birashobora kurwanya neza ikirere nisuri yimvura, kandi bikagumana ubwiza nibikorwa byububiko.
Kurengera ibidukikije no kuramba Ifu ya Redispersible latex isanzwe ikorwa hashingiwe kumikoreshereze y’amashanyarazi kandi ntisohora ibintu byangiza mugihe cyo kuyikoresha, ibyo bikaba bihuye niterambere ryiterambere ryibikoresho byubaka. Byongeye kandi, imikorere yayo myiza ituma ubunini nubunini bwibikoresho byubaka bigabanuka, bityo bikagabanya imikoreshereze yumutungo nuburemere bwibidukikije.
2. Ibibazo byifu ya redxersible powder
Igiciro cy'umusaruro ni kinini. Igikorwa cyo kubyaza umusaruro ifu ya latx isubirwamo iragoye kandi isaba inzira nyinshi nka emulion polymerisation hamwe no kumisha spray. Cyane cyane mugikorwa cyo kumisha spray, ingufu nyinshi zirakoreshwa, bityo umusaruro wacyo ni mwinshi. Ibi byaviriyemo gukoresha imipaka ifu ya redxersible latex mumishinga imwe yo kubaka igiciro gito.
Yumva neza ibidukikije Ibishobora kugabanuka ifu ya latx yunvikana nibidukikije nkubushyuhe nubushuhe. Mugihe cyo kubika no gutwara, niba ubuhehere buri hejuru cyane cyangwa ubushyuhe ntibukwiye, ifu ya latex irashobora kwegeranya cyangwa kunanirwa, ibyo bizagira ingaruka kumikorere ya redispersion nibikorwa byanyuma. Kubwibyo, ifite ibisabwa byinshi mububiko kandi igomba kubikwa ahantu humye kandi hakonje.
Imipaka yingaruka zo gukwirakwiza Nubwo ifu ya latx ishobora kugarurwa irashobora gusubirwamo mumazi, ingaruka zayo zo gutatanya ziracyari inyuma yizo emulisiyo yumwimerere. Niba amazi meza ari mabi (nk'amazi akomeye cyangwa arimo umwanda mwinshi), birashobora kugira ingaruka ku ikwirakwizwa ry'ifu ya latex kandi bikabuza imikorere yayo kutagerwaho neza. Kubwibyo, mubikorwa nyabyo, birashobora kuba nkenerwa gukoresha inyongeramusaruro zidasanzwe cyangwa guhindura ubwiza bwamazi kugirango tumenye ibisubizo byiza.
Kumenyekanisha isoko no guteza imbere porogaramu Nkibintu bishya ugereranije, ifu ya redxersible powder ifite ubumenyi buke mubihugu bimwe na bimwe bikiri mu nzira y'amajyambere cyangwa amasoko, kandi kuyiteza imbere no kuyashyira mu bikorwa birabujijwe. Nubwo ikora neza, ibigo bimwe byubwubatsi gakondo ntibyemera cyane kubera ibiciro byumusaruro mwinshi nibiciro. Igihe nisoko ryamasomo biracyakenewe kugirango duhindure uko ibintu bimeze.
Irushanwa riva mubindi bikoresho Hamwe niterambere ryibikoresho siyanse, ibikoresho bishya bihora bigaragara kumasoko. Ibi bikoresho bishya birashobora kwerekana imikorere isumba iyindi cyangwa igiciro gito ugereranije nifu ya redxersible powder mubice bimwe, bitera imbogamizi kumasoko yifu ya latex. Kugirango ukomeze guhatana, amasosiyete akora inganda agomba guhora atezimbere imikorere yibicuruzwa no kugenzura ibiciro.
Nkibikoresho bya polymer bikora, ifu ya redxersible latex yerekanye ibyiza byingenzi mubijyanye nibikoresho byubaka, cyane cyane mugutezimbere imikorere, kunoza ibyubaka no kongera igihe kirekire. Nyamara, ikiguzi cyacyo kinini, kumva neza ibidukikije nibibazo byo kwamamaza ntibishobora kwirengagizwa. Mu bihe biri imbere, hamwe n’iterambere ry’ikoranabuhanga no gukura kw'isoko, biteganijwe ko ifu ya redxersible latex izashyirwa mu bikorwa byinshi, kandi igiciro cyayo n'imikorere nayo izarushaho kunozwa, bityo bikagira uruhare runini mu bijyanye n'ibikoresho byo kubaka. .
