Ukutyhubela iminyaka, ukuveliswa kweerola zerabha kwenze ukuba umatshini kunye ne-automation yezixhobo zenkqubo kube nzima ngenxa yokungazinzi kweemveliso kunye nokwahluka kobukhulu benkcazo.Ukuza kuthi ga ngoku, uninzi lwazo luseyimigca yemveliso esekelwe kwi-manual-based discontinuous unit operation.Kutshanje, abanye abavelisi abakhulu beengcali baye baqala ukuqonda imveliso eqhubekayo ukusuka kwizinto zerabha ukuya ekubumbeni kunye neenkqubo ze-vulcanization, eziye zaphinda kabini ukusebenza kakuhle kwemveliso kunye nokuphucula kakhulu indawo yokusebenza kunye nokuqina kwabasebenzi.
Kwiminyaka yakutshanje, itekhnoloji yesitofu, i-extrusion kunye ne-winding iye yaphuhliswa ngokuqhubekayo, kwaye ukubunjwa kwerabha yerabha kunye nezixhobo ze-vulcanization zenze imveliso yerola yerabha ngokuthe ngcembe yalungiswa kwaye izenzekelayo.Ukusebenza kwe-rubber roller kunempembelelo enkulu kuwo wonke umatshini, kwaye ingqongqo kakhulu kwinkqubo yokusebenza kunye nomgangatho wokuvelisa.Uninzi lweemveliso zayo ziye zahlelwa njengeemveliso ezintle.Phakathi kwabo, ukhetho lwerabha kunye neplastiki kunye nokulawulwa kokuchaneka komgangatho wemveliso yinto ephambili.Umphezulu we-rubber we-rubber roller awuvumelekanga ukuba ube naluphi na ukungcola, i-blisters kunye ne-bubbles, kungabikho izibazi, iziphene, ii-grooves, ii-cracks kunye neziponji zendawo kunye neziganeko ezahlukeneyo ezithambileyo nezinzima.Ngesi sizathu, i-roller yerabha kufuneka icoceke ngokupheleleyo kwaye icokiseke kuyo yonke inkqubo yemveliso, ukuze kuqatshelwe ukusebenza okudityanisiweyo kunye nomgangatho wobugcisa.Inkqubo yokudibanisa iplastiki yerabha kunye nesiseko sesinyithi, ukuncamathisela, ukubunjwa kwenaliti, i-vulcanization kunye nokugaya ke ngoko ibe yinkqubo ye-high-tech.
Ukulungiswa kwerabha
Kwimiqulu yerabha, ukuxutywa kwerabha yeyona nto ibalulekileyo.Kukho iintlobo ezingaphezu kwe-10 zemathiriyeli yerabha yeerola zerabha ukusuka kwirabha yendalo kunye nerabha yokwenziwa ukuya kwizinto ezikhethekileyo.Umxholo we-rubber ngu-25% -85%, kwaye ukuqina ngumhlaba (0-90) degrees, obubanzi obubanzi.Ke ngoko, indlela yokuxuba ezi khompawundi ngokufanayo ibe yingxaki enkulu.Indlela eqhelekileyo kukusebenzisa i-mill evulekileyo yokuxuba kunye nokusebenza ngendlela yeendidi ze-master batches.Kwiminyaka yakutshanje, iinkampani ziye zatshintshela kwimixube yangaphakathi edibanisayo ukulungisa iikhompawundi zerabha ngokuxutywa okwahlukeneyo.
Emva kokuba i-rubber ixutywe ngokufanayo, i-rubber kufuneka ihlulwe nge-rubber filter ukuze isuse ukungcola kwi-rubber material.Emva koko sebenzisa i-calender, i-extruder, kunye nomatshini wokulambisa ukwenza ifilimu okanye umcu ngaphandle kwamaqamu kunye nokungcola kokwenza i-rubber roller.Ngaphambi kokwenza, ezi filimu kunye nemicu yokuncamathelisa kufuneka ihlolwe ngokungqongqo ukukhawulela ixesha lokupaka, ukugcina indawo entsha kunye nokuthintela ukunamathela kunye ne-extrusion deformation.Ngenxa yokuba uninzi lwee-rubber rollers ziyimveliso engabunjwanga, xa kukho ukungcola kunye neebhubhu ebusweni be-rubber, i-blisters ingabonakala xa umhlaba uphantsi emva kokutshatyalaliswa kwe-vulcanization, okuya kubangela ukuba i-roller yonke yerabha ilungiswe okanye ikhutshwe.
