Mu mishinga y'ubwubatsi n'ubwubatsi, akamaro k'udupfundikizo tw'ingingo ntikagombye kurenza urugero. Ibi bikoresho bigira uruhare runini mu kwemeza ko inyubako zigumaho kandi zirambye binyuze mu gufunga icyuho no gukumira kwinjira mu mazi, umwuka n'ibindi bintu byangiza. Mu bwoko butandukanye bw'udupfundikizo tw'ingingo, udupfundikizo tw'udu ...
Agakoresho ko gufunga ingingo gapima PU gakoresha ikoranabuhanga ryo mu bwoko bwa elasticni ibikoresho bimwe bikozwe muri polyurethane bigaragaza ubushobozi bwo gutemba neza no kwipima. Byakozwe hamwe n'uruvange rwa polyol na isocyanate, iyo bivanze, bihura n'ingaruka za shimi kugira ngo bikore sealant iramba kandi yoroshye. Uburyo iyi sealant yipima ubwayo butuma ikwirakwira neza ku buso butambitse, bigatuma irangira neza kandi neza.
Uburyo bwo gufunga ibintu butuma ingingo zihagarara neza ni ikindi kintu cy'ingenzi kiyitandukanya. Ifite ubushobozi bwo gufunga ibintu neza kandi ishobora kwihanganira ihindagurika ry'ubushyuhe, imiterere y'ingingo, cyangwa guhindagura. Iyi miterere ituma ingingo zifunga ibintu ziguma uko zari zimeze nubwo haba hari imihindagurikire y'imiterere y'ingingo, bikagabanya ibyago byo kwangirika kw'ingingo no kwangirika kw'inyubako nyuma yaho.
Ibyiza:
Ifu yo gufunga ingingo ya PU ifite ubushobozi bwo kwihuza itanga inyungu nyinshi ugereranyije n'izindi nyunganizi. Icya mbere, ubushobozi bwayo bwo kwihuza bukuraho ko hakenewe ibikoresho cyangwa tekiniki z'inyongera kugira ngo irangire neza. Ibi ntibigabanya gusa igihe n'imbaraga ahubwo binatuma isura ihoraho ku nyunganizi zifunze.
Byongeye kandi, uburyo iyi sealant ikora neza cyane butuma ishobora kwakira ingingo zigenda zidacika cyangwa ngo zicike. Ubu buryo bworoshye ni ingirakamaro cyane cyane mu nyubako zihura n’impinduka nyinshi z’ubushyuhe cyangwa imitwaro iremereye. Ubushobozi bwo kwihanganira imihindagurikire y’ikirere bwongera igihe kirekire cy’ingingo zifunze, bigagabanya gukenera gusanwa cyangwa gusanwa kenshi.
Byongeye kandi, agakoresho ko gufunga k’urukuta gakoresha PU gafite ubushobozi bwo gufata neza ibintu bitandukanye, harimo sima, ibyuma, imbaho na pulasitiki. Ubu buryo butandukanye butuma gakoreshwa mu buryo butandukanye, nko kwagura insinga, kugenzura insinga no gufunga uruziga. Agakoresho ko gufunga k’urukuta gahuye n’ibikoresho bitandukanye bituma gafatana neza kandi gafunga neza, bikongera imikorere y’inyubako muri rusange.
Porogaramu:
Ifu yo gufunga inyunganiramirire ya PU ikoreshwa cyane mu mishinga myinshi y'ubwubatsi n'ubwubatsi. Ikunze gukoreshwa mu nyubako z'ubucuruzi n'iz'abaturage, ibiraro, imihanda minini, ibibuga by'indege, n'inganda. Harimo zimwe mu nshingano zihariye zirimo:
1. Ingano zo Kwagura:
Ifu yo gufunga ingingo ya PU ikora neza ni nziza mu gufunga ingingo zo kwaguka mu nyubako za sima. Izi ngingo zifasha mu buryo busanzwe bwo kugenda kw'inyubako bitewe n'impinduka z'ubushyuhe cyangwa gutuza. Uburebure bw'ifu yo gufunga butuma yaguka kandi igafatana n'ingingo, bikarinda amazi kwinjira no kugumana ubusugire bw'inyubako.
2. Ibyuma byo kugenzura:
Ingingo zo kugenzura zikorwa ku bushake mu byuma bya sima kugira ngo zigenzure guturika guterwa no gucika. Ifunze neza ingingo zo mu bwoko bwa PU elastic, ikarinda kwinjira k'ubushuhe, imiti n'imyanda. Binafasha kugumana ubuso bwiza kandi bungana, bikongera ubwiza bw'inyubako.
3. Gufunga uruziga:
Iyi sealant ikunze gukoreshwa mu gufunga impande z'amadirishya, inzugi n'indi myanya. Imiterere yayo myiza yo gufatana ituma ifunga idafata amazi kandi idafite umwuka, ikarinda gutakaza ingufu no kongera ingufu mu nyubako.
Ifu ya PU elastic ikora ku buryo bwikora itanga inyungu zitandukanye zituma iba amahitamo meza mu bikorwa bitandukanye by’ubwubatsi n’ubwubatsi. Imiterere yayo yo kwiyubaka, ubushobozi bwayo bwo kwiyubaka no gufata neza bigira uruhare mu kuramba, imikorere, n’ubwiza bw’imfuruka zifunze. Uko inganda z’ubwubatsi zikomeza gutera imbere, byitezwe ko icyifuzo cya PU elastic ikora ku buryo bwikora kiziyongera, bitewe n’imikorere yayo myiza n’ubushobozi bwayo bwo gukora ibintu bitandukanye.
