Turi indashyikirwa mugutanga ubuziranenge - OEM na ODMibisubizo kubafatanyabikorwa bacu,

bishobotse mugukata - tekinoroji yubuhanga nubuhanga buke bwo gukora.

Irahari muburyo bwa paste, amazi cyangwa ifuro, bisaba oya kuri - kuvanga urubuga. Irangiza gukira kwihuza nubushyuhe bwo mu kirere (cyangwa amatsinda akora hejuru yubutaka), ikora ibicuruzwa bikomeye hamwe na elastique, gukomera cyangwa gufatana. Imiterere ya molekuline irimo amatsinda ya urethane (- NHCOO -), itanga ibikoresho bifite ibikoresho byiza bya mashini, birwanya ikirere ndetse no gufatira hamwe, bigatuma bikoreshwa cyane mubice nko gufunga, guhuza, gukumira amazi no kubira ifuro. Ikintu kimwe - kigizwe na polyurethane gitandukanye nikintu kinini {{7} uruhare mu kubaka. Mugihe cyo kuyikoresha, irashobora gukira bitaziguye hifashishijwe ibidukikije byo hanze, nkubushuhe nubushuhe, kugabanya neza ibiciro byubwubatsi no gukora ibikoresho bya polymer byoroshye, bifatanye, kandi bikomeye.

Ikintu kimwe - kigizwe na polyurethane, hamwe nibiranga "biteguye - kugeza - gukoresha, imikorere yizewe hamwe na progaramu nini yo gukoresha", byahindutse igisubizo cyiza cyo gusimbuza ibikoresho gakondo (nka reberi, asfalt, ibishishwa - bifatika) mubikorwa byinganda n’ubwubatsi. Cyane cyane nkibisabwa mubikorwa byubwubatsi no kurengera ibidukikije byiyongera, ikoreshwa ryacyo rikomeza kwaguka.

Kimwe - bigize polyurethane kashe iduha ingaruka zitunguranye ntabwo ziva muburyo bwazo gusa kumiterere ninyungu zo gukoresha.

Ifishi

Shira, ukiza muri elastomer mubushyuhe bwicyumba;

Ibyiza

Ubuhanga bukomeye (kurambura kuruhuka 300% -600%), kurwanya amazi no guhangana nikirere, bikwiranye no gufunga inyubako n’ibice by’imodoka;

Ibyiza

Oya kuri - ikibanza gikenewe mugihe cyubwubatsi, cyiteguye gukoresha nyuma yo gukuramo, kandi gishobora guhuza no kwimura insimburangingo nyuma yo gukira.

Gukiza

Igihe cyo kumisha hejuru yiminota 20-60, gukira byuzuye bifata amasaha 24-72.

Imikorere y'ibidukikije

Ikintu kimwe - kigizwe na polyurethane gifite imikorere myiza y’ibidukikije, cyujuje ibyangombwa bisabwa na GB / T 13477-2020, gifite VOC itarenze 50g / L, ntabwo irimo ibishishwa bya benzene, ibishishwa hamwe n’ibyuma biremereye, kandi birashobora gukoreshwa igihe kirekire.

Gukoresha neza kimwe - igice cya polyurethane, ni ngombwa kumva imiterere yacyo. Hano haribisobanuro birambuye byukuntu bikora binyuze "gukiza ubuhehere":

Gukiza Ubuso

Nyuma yo gusohora, igipande cyubuso bwa kashe kibanza kwitwara hamwe na H₂O mukirere, kigakora imiyoboro ya urea hanyuma ikarekura CO₂, ikora firime yubutaka. Iyi nzira muri rusange ifata amasaha 0-24.

Gukiza imbere

Igihe kirenze, ubuhehere bwinjira mubice bifata kandi bigahora bifata hamwe na - NCO ihuza imbere. Imbaraga na elastique bigera buhoro buhoro kubigenewe. Iyi nzira ni ndende, muri rusange ifata iminsi 1-7.

Gukiza byuzuye

Ibi bivuze ko igiti gifatika cyambukiranya rwose - gihujwe imbere no hanze, bikavamo imikorere ihamye.

Iyo ubitse kimwe - bigize polyurethane, ni ngombwa gukomeza ubushyuhe buri hagati ya dogere 5 - 30 kandi ukirinda izuba ryinshi, ubushyuhe bwinshi, nubushuhe. Mugihe uhisemo polyurethane imwe igizwe, tekereza substrate. Amahitamo akwiye arimo ibyuma, beto, plastike, hamwe nibisabwa hanze. Kugira ngo ukoreshe hanze, tekereza kurwanya ikirere no kwinjiza UV. Guhitamo ibyiza nibyo bibereye ibidukikije.
