Amazi ya Polyurethane yo guhuza amazi
Ibisobanuro
Ongeramo umukozi wo guhuza bishobora kugabanya ububengerane bwikibiriti, ariko umukozi wo guhuza akunda guhura nubutaka, bigabanya ituze ryamavuta, kandi niba kuvanga bitaringaniye, hariho ibibazo nkitandukaniro ryurumuri rwikibiriti.Kubwibyo rero, kugirango bakemure ingaruka mbi ziterwa no kongeramo imiti, abantu batangiye kwita kubushakashatsi bwakozwe na polyurethane yo mu mazi yo mu mazi hamwe na microsphere yo mu mazi polyurethane yo mu bwoko bwa poliurethane ihuza utabanje kongeramo imiti.
1. Kuzimanganya Amazi ya Polyurethane Resin
Kwiyubaka kwonyine bivuga ibishishwa bifitemo ingaruka zo guhuza isura nyuma yo gukora firime utiriwe wongeramo ifu yo guhuza cyangwa ibishashara kuri resin.Igikoresho cyo guhuza ibinyabuzima gifite ubwuzuzanye n’ibindi bisigazwa hamwe n’ibipimo bisa na byo nyuma yo gukora firime kubera ko ibiyigize bifite imiterere isa n’umubiri n’imiti hamwe n’imiterere y’amatsinda ya optique hamwe nuduce duto duto, bikemura neza ibibazo biterwa no kongeramo imiti.Muri icyo gihe kimwe, bitewe n’uko indangagaciro yo kwanga ibintu byongeweho guhuza imashini hamwe na molekile ya coating idakoreshwa, imitungo yombi yo guhuza no gukorera mu mucyo ntishobora gusuzumwa, kandi ibisabwa mu gusaba bimwe ntibishobora kubahirizwa.Kubwibyo, kwishyiriraho ibishishwa bidakoresha ibikoresho byo hanze byashimishije cyane.
Amazi yo mu mazi polyurethane yonyine azimangana nta kintu na kimwe cyo guhuza yashizwemo na hydrazine hydrate post post yo kwagura urunigi.Mubikorwa bya kandi, ibice bisa nkibikoresho byo guhuza ibyara, kandi ibice bireremba hejuru yubuso bwa firime ifata, bigatuma mikorobe yo hejuru idakomera.Ubu buryo ntibukemura gusa inenge ziterwa no gukoresha imiti yo guhuza, ariko kandi bufite amavuta meza yo kwisiga, kandi birashobora no kunoza imyanda yo kwisiga, kwihuta kwihuta no kwihuta kwa firime.Irashobora gukoreshwa cyane hejuru yububiko bwuruhu, polyvinyl chloride (PVC) uruhu, uruhu rwa polyurethane, nibindi.
Ipatanti y'Ubushinwa cn106432667b iragaragaza uburyo bwo gutegura uburyo bwo guhuza ibintu byoroshye kandi byoroshye amazi yo mu mazi polyurethane yo kurangiza uruhu.Ipatanti yahinduwe ikoresha hmdi, HDI Trimer, propylene karubone glycol na acide dimethylbutyric (DMBA) nkibikoresho fatizo byingenzi na hydrazine hydrat nkumunyururu nyuma yo kwigana kugirango utegure polyurethane ikomoka kumazi.HDI Trimer mubikoresho fatizo ifite impeta y'amatsinda atatu akora.Imiterere yimpeta irahagaze mugihe cyo gukora synthesis, irashobora gukora imiyoboro ihuza imiyoboro yibicuruzwa bimwe na bimwe bya polyurethane.Ubwuzuzanye bwa micro gel yakozwe nibindi bisigazwa bya polyurethane bigabanuka mugihe cyo gukora firime.Byongeye kandi, hari urwego runaka rwa kristu muri polyurethane, biganisha ku kugabanuka gukorera mu mucyo kwa firime, kugera ku ngaruka zo kuzimya mask, no kuzamura cyane elastique, kurwanya amazi, kurwanya ibishishwa no kwihanganira kwambara firime ya polyurethane.
2. Guhindura Amazi ya Polyurethane yo mu mazi
Kubera ko kongeramo ibikoresho byo guhuza bishobora kugira ingaruka kumiterere ya firime ya coating, kandi amatsinda ya hydrophilique akubiye mumashanyarazi ya polyurethane yo mu mazi yo mu mazi azatera amazi mabi ya firime yo gutwika nyuma yo gukora firime yo kwisiga, cyane cyane iyo ikoreshejwe kubutaka bwo hejuru bwuruhu cyangwa impapuro, ibigo byinshi bitegura ibisigazwa byo guhuza binyuze muburyo bwo guhindura, nka silicone ihindura no guhuza kwambukiranya.
Mugihe cyo gukora firime ya organosilicon yahinduwe na polyurethane yo mumazi yo mu mazi, ibice bya hydrophobique organosilicon bimukira hejuru ya firime yamavuta yo kwisiga kugirango bibe mikorobe ikaze, ituma polyurethane iba ifite imiterere-karemano na organique, hamwe no kurwanya amazi, ubushyuhe ituze hamwe nubukanishi byatejwe imbere neza.Silicone yahinduye amazi yo mu bwoko bwa polyurethane matting resin yateguwe hakoreshejwe PDMS yahinduwe PTMG, diisocyanate (IPDI) na aside dimethylol propionic aside (DMPA) nkibikoresho fatizo.
Guhindura guhuza guhindura imiterere yumurongo wa polyurethane, nigisubizo cyo guhuza kwayo kugirango habeho urusobe rwinshi rwa polyurethane macromolecules.Ingano yubunini bwa lisansi ya polyurethane iriyongera, kandi amazi aguruka mugihe cyo kumisha amavuta.Ingero zifite diameter nini zikora ubuso butangaje hamwe nuburabyo buke nyuma yo guterana.Muri icyo gihe, kurwanya ubushyuhe, kurwanya amazi no kurwanya imiti ya polyurethane yateguwe n’amazi nabyo byatejwe imbere kubera imiterere y’urusobe rwinshi.Amavuta yo kwisiga ya polyurethane yo mumazi yahinduwe no guhuza imbere byateguwe nuburyo bwo kwagura urunigi.Ubuso bwa firime bwari bubi.
Umwanzuro
Nkigice cyingenzi cyogukoresha amavuta ya polyurethane yo mu mazi, amavuta yo kwisiga yitabiriwe ninganda zitwikiriye.Nyamara, ibicuruzwa bimwe bifite umutekano muke.Kubera ko bidakenewe kongeramo ibikoresho byo guhuza ibifuniko, kwifata ubwabyo byo kwisiga bigira imbaraga zikomeye hamwe nibikorwa byiza byo gutwikira, bizahinduka inzira yiterambere mugihe kizaza.
