Gukora
Uburyo bwo gushushanya imigozi ya rubber bushingiye ahanini ku gupfunyika imigozi ku gice cy'imbere cy'icyuma, harimo uburyo bwo gupfunyika, uburyo bwo gusohora, uburyo bwo gushushanya, uburyo bwo gusuka igitutu n'uburyo bwo gutera. Kuri ubu, ibicuruzwa by'ingenzi byo mu gihugu ni ugupfunyika no gushushanya hakoreshejwe ikoranabuhanga cyangwa intoki, kandi ibihugu byinshi by'amahanga byakoze ikoranabuhanga rikora. Imigozi minini n'iciriritse ya rubber ikorwa hakoreshejwe uburyo bwo gushushanya, gushushanya no gushushanya hakoreshejwe firime isohoka cyangwa gushushanya no gushushanya hakoreshejwe kaseti isohoka. Muri icyo gihe, mu buryo bwo gushushanya, ibisobanuro, ingano n'imiterere y'isura bigenzurwa na mudasobwa nto, kandi bimwe na bimwe bishobora no gushushanywa hakoreshejwe uburyo bwo gusohora icyuma mu nguni y'iburyo n'uburyo bwo gusohora bufite ishusho yihariye.
Uburyo bwo gushushanya bwavuzwe haruguru ntibushobora kugabanya gusa imbaraga z'umurimo, ahubwo bunakuraho uduheri dushobora kubaho. Kugira ngo hirindwe ko agapira ka kabutura kadahinduka mu gihe cyo gukurura no gukumira ko uduheri n'ibisuguti bivuka, cyane cyane ku gapira kabutura gakozwe n'uburyo bwo gupfunyika, hagomba gukoreshwa uburyo bworoshye bwo gukandagira hanze. Ubusanzwe, ubuso bw'inyuma bw'agapira kabutura bupfunyikwa kandi bugapfundikirwa n'imyenda myinshi y'ipamba cyangwa umwenda wa nylon, hanyuma bugakomezwa kandi bugashyirwamo umugozi w'icyuma cyangwa umugozi wa fibre. Nubwo ubu buryo bwamaze gukoreshwa imashini, agapira kagomba gukurwaho nyuma yo gukurura kugira ngo habeho "cecal", ibyo bigatuma inzira yo gukora igorana. Byongeye kandi, ikoreshwa ry'agapira kabutura n'umugozi wo kuzunguruka ni bike cyane kandi ikoreshwa ni rinini.
Ku byuma bito n'ibito bito bizingiramo imipira, hashobora gukoreshwa uburyo butandukanye bwo gukora, nko gupakira intoki, gusohora imyenge, gusuka igitutu, gutera no gusuka. Kugira ngo hongerwe umusaruro, uburyo bwinshi bwo gushushanya ubu burakoreshwa, kandi uburyo bwo gukoresha neza ni bwinshi cyane kuruta uburyo bwo kudashushanya. Igitutu cyo gutera, gutera umukungugu ukomeye no gusuka umukungugu w'amazi byabaye uburyo bw'ingenzi bwo gukora.
Guhindura imiterere y'ibintu mu buryo bwa Vulcanization
Kugeza ubu, uburyo bwo gukoresha vulcanization bw'amapine manini n'aciriritse azunguruka amapine buracyari vulcanization y'ikigega cy'amazi. Nubwo uburyo bwo gukoresha pressurization buhindagurika bwahinduwe, ntabwo bucika ku mutwaro uremereye wo gutwara, guterura no gupakurura amapine. Isoko y'ubushyuhe bwa vulcanization ifite uburyo butatu bwo gushyushya: umwuka, umwuka ushyushye n'amazi ashyushye, naho uburyo busanzwe ni umwuka. Amapine azunguruka amapine afite ibisabwa byihariye bitewe n'uko igice cy'imbere cy'icyuma gihuye n'umwuka w'amazi akoresha vulcanization y'umwuka itaziguye, kandi igihe kizongerwa inshuro 1 kugeza kuri 2. Muri rusange akoreshwa ku mapine azunguruka amapine afite impande z'icyuma zidafite aho ziboshye. Ku mapine adasanzwe azunguruka amapine adashobora kuvunguka hakoreshejwe ikigega cy'amazi, hari igihe amazi ashyushye akoreshwa mu kuvunguka amapine, ariko uburyo bwo kuvura umwanda w'amazi bugomba gukemurwa.
Kugira ngo hirindwe ko irangi n'inkingi y'icyuma bidahinduka bitewe n'igabanuka ry'itandukaniro ry'ubushyuhe hagati y'ikirangi cy'urumuri n'inkingi y'urumuri, ubusanzwe irangi rikoresha uburyo bwo gushyushya buhoro no kongera umuvuduko, kandi igihe cyo gushyushya kiba kirekire cyane ugereranyije n'igihe cyo gushyushya gisabwa na irangi ubwaryo. . Kugira ngo irangi rihuze neza imbere no hanze, kandi kugira ngo irangi rihuze neza, irangi rinini riguma mu gikoresho amasaha 24 kugeza kuri 48, ni ukuvuga inshuro zigera kuri 30 kugeza kuri 50 z'igihe gisanzwe cyo gushyushya.
Udupira duto n'uduto twa rubber ubu duhinduka cyane cyane plaque vulcanizing press molding vulcanization, bihindura burundu uburyo gakondo bwo gukoresha vulcanization muri rubber rollers. Mu myaka ya vuba aha, imashini zikoresha inshinge zakoreshejwe mu gushyiraho imashini zikoresha ...
Muri iki gihe, irangi ry'amazi rigaragazwa na polyurethane elastomer (PUR) ryateye imbere cyane mu gukora irangi ry'urumuri, kandi ryafunguye uburyo bushya bwo kuyitunganya no kuyihindura. Rikoresha uburyo bwo kuyisuka kugira ngo rikureho ibikorwa bigoye byo kuyibumba n'ibikoresho binini byo kuyitunganya, byoroshya cyane uburyo bwo kuyikora. Ariko, ikibazo gikomeye ni uko irangi rigomba gukoreshwa. Ku irangi rinini rya rubri, cyane cyane ku bicuruzwa bitandukanye, ikiguzi cyo kuyitunganya kiriyongera cyane, ibyo bikaba bitera ingorane nyinshi mu kwamamaza no kuyikoresha.
Mu rwego rwo gukemura iki kibazo, hagaragaye uburyo bushya bwo gukora PUR rubber roller idafite ibumba mu myaka ya vuba aha. Ikoresha polyoxypropylene ether polyol (TDIOL), polytetrahydrofuran ether polyol (PIMG) na diphenylmethane diisocyanate (MDl) nk'ibikoresho fatizo. Ikora vuba nyuma yo kuvanga no kuvanga, kandi isukwa ku gice cy'icyuma gitemba rubber roller kigenda gihindagurika buhoro buhoro. , Ikorwa intambwe ku yindi mu gihe cyo gusuka no gusya, amaherezo rubber roller irakorwa. Ubu buryo ntibuba ari bugufi gusa mu bikorwa, bufite imashini nyinshi n'imikorere yihariye, ahubwo bunakuraho gukenera ibumba nini. Ishobora gukora rubber roller zifite imiterere itandukanye n'ingano zitandukanye uko ubyifuza, ibyo bikaba bigabanya cyane ikiguzi. Yabaye icyerekezo nyamukuru cy'iterambere rya PUR rubber roller.
Byongeye kandi, utumashini duto twa rubber dukoreshwa mu gukora ibikoresho byikora mu biro hakoreshejwe silicone y'amazi natwo turimo gutera imbere vuba ku isi yose. Tugabanyijemo ibyiciro bibiri: gushyushya (LTV) no gushyushya ubushyuhe bw'icyumba (RTV). Ibikoresho bikoreshwa nabyo bitandukanye na PUR yavuzwe haruguru, birema ubundi bwoko bw'uburyo bwo gucukura. Aha, ikibazo cy'ingenzi ni uburyo bwo kugenzura no kugabanya ubukana bw'umusemburo wa rubber kugira ngo ubashe kugumana umuvuduko runaka n'umuvuduko wo gusohora.
