Gushiraho
Rubber roller molding ahanini ni ugushira reberi hejuru yicyuma, harimo uburyo bwo gupfunyika, uburyo bwo kuvoma, uburyo bwo kubumba, uburyo bwo gutera inshinge nuburyo bwo gutera inshinge.Kugeza ubu, ibicuruzwa by’imbere mu gihugu ni imashini cyangwa intoki zometse kandi zikozwe, kandi ibihugu byinshi by’amahanga byabonye imashini zikoresha.Ibinini binini kandi biciriritse bya reberi byakozwe muburyo bwo gushushanya, guhora ushushanya ukoresheje firime yakuweho cyangwa guhora uhindagurika ukoresheje kaseti.Muri icyo gihe, muburyo bwo kubumba, ibisobanuro, ibipimo nuburyo bwo kugaragara bihita bigenzurwa na microcomputer, kandi bimwe bishobora no kubumbabumbwa nuburyo bwo gukuramo impande zombi iburyo no gusohora bidasanzwe.
Uburyo bwo kubumba bwavuzwe haruguru ntibushobora kugabanya ubukana bwumurimo gusa, ahubwo burashobora no gukuraho ibisebe bishoboka.Kugirango wirinde icyuma cya reberi kidahinduka mugihe cy’ibirunga no gukumira ibisekuruza byinshi hamwe na sponges, cyane cyane kuri reberi ya reberi yabumbwe nuburyo bwo gupfunyika, hagomba gukoreshwa uburyo bworoshye bwo gukanda.Mubisanzwe, hejuru yinyuma ya reberi irapfunyika kandi igakomeretsa ibice byinshi byimyenda ya pamba cyangwa igitambaro cya nylon, hanyuma bigashyirwaho hanyuma bigashyirwaho igitutu cyuma cyangwa umugozi wa fibre.Nubwo ubu buryo bumaze gukoreshwa, imyambarire igomba gukurwaho nyuma y’ibirunga kugirango ikore "cecal", igora inzira yo gukora.Byongeye kandi, gukoresha imyenda yo kwambara nu mugozi uzunguruka ni bike cyane kandi kubikoresha ni byinshi.imyanda.
Kuri reberi ntoya na mikorobe, uburyo butandukanye bwo gukora burashobora gukoreshwa, nko guterura intoki, guteramo ibyari, gutera inshinge, gutera inshinge.Kugirango tunoze umusaruro ushimishije, uburyo bwinshi bwo kubumba bwakoreshejwe ubu, kandi ubunyangamugayo buri hejuru cyane kurenza uburyo butabumbabumbwe.Umuvuduko wo gutera inshinge, gutera inshinge zikomeye no gusuka reberi y'amazi byabaye uburyo bwingenzi bwo gukora.
Ibirunga
Kugeza ubu, uburyo bwa volcanisation ya rinini nini nini nini nini ya reberi iracyari ikigega cya volcanisation.Nubwo uburyo bworoshye bwo guhinduranya igitutu bwahinduwe, ntibushobora kuva ku mutwaro uremereye wumurimo wo gutwara, guterura no gupakurura.Inkomoko yubushyuhe bwa volcanisation ifite uburyo butatu bwo gushyushya: umwuka, umwuka ushyushye namazi ashyushye, kandi inzira nyamukuru iracyari parike.Ibikoresho bya reberi hamwe nibisabwa bidasanzwe bitewe no guhuza ibyuma byumuyaga hamwe numwuka wamazi bifata ibirunga bitaziguye, kandi igihe kizongerwa inshuro 1 kugeza kuri 2.Mubisanzwe bikoreshwa mubikoresho bya reberi hamwe nibyuma byuma.Kubikoresho bya reberi bidasanzwe bidashobora guterwa nigitereko cy’ibirunga, amazi ashyushye rimwe na rimwe akoreshwa mu kurunga, ariko hagomba gukemurwa uburyo bwo kuvura umwanda w’amazi.
Kugirango wirinde reberi hamwe nicyuma cyicyuma kidasibanganywa bitewe no kugabanuka gutandukanye gutandukanya itandukanyirizo ryubushyuhe hagati ya reberi na reberi ya reberi, ubusanzwe ibirunga bifata uburyo bwo gushyushya buhoro no kongera umuvuduko, kandi igihe cy’ibirunga ni kinini birebire kuruta igihe cyo kurunga bisabwa na reberi ubwayo..Kugirango ugere ku kirunga kimwe imbere no hanze, no gukora ubushyuhe bwumuriro wibyuma na reberi bisa, uruziga runini rwa reberi ruguma muri tank mu masaha 24 kugeza 48, ibyo bikaba bikubye inshuro 30 kugeza kuri 50 igihe gisanzwe cy’ibirunga bisanzwe; .
Ibikoresho bito bito na mikorobe byahinduwe ubu byahinduwe mubisahani bya volcanizing press molding vulcanisation, bihindura rwose uburyo bwa gakondo bwibirunga bwa reberi.Mu myaka yashize, imashini zitera inshinge zakoreshejwe mugushiraho ibishushanyo na vacuum vulcanisation, kandi ibishusho birashobora gufungurwa no gufungwa byikora.Urwego rwo gukanika no gukoresha imashini rwaratejwe imbere cyane, kandi igihe cyo kurunga ni gito, umusaruro uva hejuru, kandi ibicuruzwa ni byiza.Cyane cyane iyo ukoresheje imashini itera reberi imashini itwara imashini, inzira ebyiri zo kubumba no kurunga zahujwe hamwe, kandi igihe gishobora kugabanywa kugeza ku minota 2 kugeza kuri 4, kikaba cyarabaye icyerekezo cyingenzi mugutezimbere umusaruro wa rubber.
Kugeza ubu, reberi y'amazi ihagarariwe na polyurethane elastomer (PUR) yateye imbere byihuse mu gukora ibizunguruka, kandi byafunguye uburyo bushya bwo guhindura ibintu.Ifata ifomu isuka kugirango ikureho ibikorwa bigoye byo kubumba hamwe nibikoresho byinshi by’ibirunga, byoroshya cyane uburyo bwo gukora ibizunguruka.Ariko, ikibazo kinini nuko ibishushanyo bigomba gukoreshwa.Kuri reberi nini cyane cyane kubicuruzwa kugiti cye, igiciro cyumusaruro cyiyongereye cyane, kizana ingorane zikomeye mukuzamura no gukoresha.
Kugirango iki kibazo gikemuke, inzira nshya ya PUR rubber roller idafite inganda zakozwe mumyaka yashize.Ikoresha polyoxypropylene ether polyol (TDIOL), polytetrahydrofuran ether polyol (PIMG) na diphenylmethane diisocyanate (MDl) nkibikoresho fatizo.Irakora vuba nyuma yo kuvanga no gukurura, kandi igasukwa mubwinshi buhoro buhoro buhoro buhoro buhoro., Byagaragaye intambwe ku yindi mugihe cyo gusuka no gukiza, hanyuma amaherezo ya reberi irakorwa.Iyi nzira ntabwo ari ngufi gusa mubikorwa, murwego rwo hejuru mukoresha imashini no kwikora, ariko kandi ikuraho ibikenewe kubumba byinshi.Irashobora gukora reberi yerekana ibintu bitandukanye nubunini uko bishakiye, bigabanya cyane igiciro.Byahindutse icyerekezo nyamukuru cyiterambere cya PUR reberi.
Byongeye kandi, imashini nziza ya reberi ikoreshwa mugukora ibikoresho byo gutangiza ibiro hamwe na silicone ya silicone nayo iratera imbere byihuse kwisi yose.Bagabanijwemo ibyiciro bibiri: gukiza ubushyuhe (LTV) no gukiza ubushyuhe bwicyumba (RTV).Ibikoresho byakoreshejwe nabyo bitandukanye na PUR yavuzwe haruguru, ikora ubundi bwoko bwa casting.Hano, ikibazo gikomeye cyane nuburyo bwo kugenzura no kugabanya ubukonje bwuruganda rwa reberi kugirango rushobore kugumana umuvuduko runaka no kwihuta.
