Itandukaniro riri hagati ya Polyurethane ishingiye ku mazi na Polyurethane ishingiye ku mavuta
Igitambaro cya polyurethane kidapfa amazi gishingiye ku mazi ni ibikoresho bidapfa amazi bifite molekile nyinshi kandi bifatanye neza kandi ntibipfa kwinjira. Gifata neza ibintu bishingiye kuri sima nka sima, amabuye n'ibyuma. Iki gicuruzwa gifite imiterere ihamye ya shimi kandi gishobora kwihanganira izuba igihe kirekire. Gifite imiterere yo kugorama no kurekura cyane.
Ibiranga Imikorere y'Igicuruzwa
1. Ishusho: Umuti ugomba kuba udafite uduce nyuma yo kuvanga kandi ukaba umeze kimwe.
2. Ifite imbaraga zo gukomera cyane, uburebure bwinshi, ubushyuhe bwiza, imikorere myiza mu bushyuhe buri hejuru n'ubuke, kandi ibasha kwihuza neza no gupfunyika, guturika no guhinduka kw'ubutaka.
3. Gufatana kwayo ni byiza, kandi nta buryo bwo kuyitunganya bukenewe ku bintu bitandukanye byujuje ibisabwa.
4. Ipfundikizo rirakama rigakora agapfundikizo, hanyuma rigakomeza kunyuramo amazi, rirwanya ingese, rirwanya ibishingwe, kandi rigakomeza kunanirwa.
5. Imikorere yayo mu bidukikije ni myiza, kuko idafite ibice bya benzene cyangwa lisansi y'amakara, kandi nta kindi kintu kiyikomokaho gikenewe mu gihe cyo kubaka.
6. Ni ikintu kimwe gikoreshwa mu buryo bukonje kandi cyoroshye gukoresha no gushyiramo.
Ingano y'ikoreshwa ry'ibicuruzwa
1. Bikwiriye ibyumba byo munsi y'ubutaka, aho guparika imodoka munsi y'ubutaka, inzira ya gari ya moshi ifunguye n'inzira zo mu mazi
2. Ibikoni, ubwiherero, amabati yo hasi, balkoni, ibisenge bitagaragara.
3. Gukingira amazi mu buryo buhagaze no gukumira amazi mu mfuruka, mu miyoboro n'ibindi bice bito, ndetse no gufunga imiyoboro yo gukumira amazi.
4. Gukingira amazi kuri pisine, amasoko y'ubukorano, ibigega by'amazi, n'imiyoboro yo kuhira.
5. Gukingira amazi ahantu ho guparika imodoka no ku bisenge by'urukuta.
Irangi rikoreshwa mu gusiga amazi rikozwe muri polyurethane rikoresheje amavuta ni irangi rinini rikoreshwa mu gusiga amazi rituma rikomera ku buso. Rikozwe muri isocyanates na polyol nk'ibikoresho by'ingenzi, hamwe n'ibikoresho by'inyongera bitandukanye nko kuvanga ibikoresho bitagira amazi na pulasitiki, kandi rikorwa n'uburyo bwihariye bwo kubura amazi mu bushyuhe bwinshi no gupima polymerization. Iyo rikoreshejwe, rishyirwa ku irangi ridashobora amazi, maze agapira gakomeye, koroshye kandi gafite umugozi gakorwa ku buso bwa irangi rikoreshwa mu gusiga amazi hagati y'itsinda rya -NCO rya polyurethane prepolymer n'ubushuhe buri mu kirere.
Ibiranga Imikorere y'Igicuruzwa
1. Ishusho: Iyi poroduyi ifite umubiri umwe umeze nk'ufite gel n'udusimba.
2. Igice kimwe, cyiteguye gukoreshwa aho giherereye, gikora ukonje, cyoroshye gukoresha, kandi ibisabwa ku bushuhe bw'ubutaka ntabwo ari agahato.
3. Gufata neza: Gufata neza sima, sima, ibumba, sima, ibiti, nibindi, ibikoresho by'ubwubatsi, gushobora kwihuza neza no gucika, kwangirika no guhinduka kw'ubutaka.
4. Firime idafite imigozi: Ifata neza, nta mpamvu yo gushyira primer ku bintu bitandukanye byujuje ibisabwa.
5. Ingufu nyinshi zo gukurura filime, umuvuduko munini wo kurekura, uburimbane bwiza, ubushobozi bwo guhuza neza no guhindagurika kw'igice cy'imbere.
6. Kurwanya imiti, kugabanya ubushyuhe, kugabanya gusaza, kugabanya ifu, no kugabanya amazi. Uburyo bwo gukoresha ibicuruzwa
Irangi rikoreshwa muri polyurethane ritaziba amazi rishobora gukoreshwa mu kubaka inyubako nshya n'iza kera, ibisenge, amazu yo munsi y'ubutaka, ubwiherero, pisine, imishinga yo kwirwanaho, n'ibindi. Rishobora kandi gukoreshwa mu kubaka imiyoboro y'ibyuma bitaziba amazi.
Itandukaniro riri hagati ya polyurethane ishingiye ku mavuta na polyurethane ishingiye ku mazi:
Polyurethane ishingiye ku mavuta ifite ingano ikomeye kurusha polyurethane ishingiye ku mazi, ariko ikozwe muri isocyanate, polyether, n'ibindi bikoresho by'inyongera bitandukanye nka mixed latent curing agent na plasticizers, byateguwe hakoreshejwe uburyo bwihariye ku bushyuhe bwinshi, nko gukuraho amazi no gukora polymerization reaction. Ifite urwego runini rw'umwanda, ugereranije na polyurethane ishingiye ku mazi, ikaba ari ikintu kibisi kandi kidahumanya ibidukikije kidafite umwanda. Ikwiriye gukoreshwa mu nzu, nko mu gikoni no mu bwiherero.
