Kwiminyaka edlulileyo, ukuveliswa kweerola zerabha kwenze ukuba kube nzima ukwenza oomatshini kunye nokuzisebenzela ngokuzenzekelayo kwezixhobo zenkqubo ngenxa yokungazinzi kweemveliso kunye nokwahluka kweenkcukacha zobungakanani. Okwangoku, uninzi lwazo lusasebenza ngesandla, luseyimigca yemveliso yokusebenza kweyunithi engaguqukiyo. Kutshanje, abanye abavelisi abakhulu abaziingcali baqalise ukuvelisa imveliso eqhubekayo ukusuka kwizixhobo zerabha ukuya kwiinkqubo zokubumba kunye ne-vulcanization, nto leyo eye yaphinda kabini ukusebenza kakuhle kwemveliso kwaye yaphucula kakhulu imeko yokusebenza kunye nobunzima babasebenzi.
Kwiminyaka yakutshanje, iteknoloji yokujova, ukukhupha kunye nokujika i-wind iye yaphuhliswa rhoqo, kwaye izixhobo zokubumba kunye ne-vulcanization ze-rubber roller zenze imveliso ye-rubber roller yasebenza ngoomatshini kwaye yazenzekela kancinci kancinci. Ukusebenza kwe-rubber roller kunempembelelo enkulu kumatshini wonke, kwaye ingqongqo kakhulu ekusebenzeni kwenkqubo kunye nomgangatho wemveliso. Uninzi lweemveliso zayo zihlelwe njengeemveliso ezintle. Phakathi kwazo, ukukhethwa kwezinto zerabha kunye neplastiki kunye nolawulo lokuchaneka kobukhulu bemveliso zezona zinto zibalulekileyo. Umphezulu werabha we-rubber roller awuvumelekanga ukuba ube nokungcola, ama-blister kunye nama-bubbles, ingasathethwa ke ngamanxeba, iziphene, imingxunya, imifantu kunye neziponji zasekuhlaleni kunye nezinye izinto ezithambileyo neziqinileyo. Ngenxa yesi sizathu, i-rubber roller kufuneka icoceke ngokupheleleyo kwaye ibe nocoselelo kuyo yonke inkqubo yemveliso, ukuze kufezekiswe ukusebenza okudibeneyo kunye nomgangatho wobugcisa. Inkqubo yokudibanisa iplastiki yerabha kunye nesiseko sesinyithi, ukuncamathisela, ukubumba ngenaliti, ukuvulcanization kunye nokusila ke ngoko ibe yinkqubo yobuchwepheshe obuphezulu.
Ukulungiswa kwerabha
Kwiirola zerabha, ukuxuba irabha yeyona nto ibalulekileyo. Kukho iintlobo ezingaphezu kwe-10 zezinto zerabha zeerola zerabha eziqala kwirabha yendalo kunye nerabha yokwenziwa ukuya kwizinto ezikhethekileyo. Umxholo werabha yi-25%-85%, kwaye ubunzima bungamadigri omhlaba (0-90), agubungela uluhlu olubanzi. Ke ngoko, indlela yokuxuba ezi zixhobo ngokufanayo ibe yingxaki enkulu. Indlela eqhelekileyo kukusebenzisa i-open mill yokuxuba kunye nokucubungula ngendlela yee-master batches ezahlukeneyo. Kwiminyaka yakutshanje, iinkampani ziye zatshintshela ngakumbi kwi-interneshing internal mixers ukulungiselela ii-rubber compounds ngokusebenzisa ukuxuba okuhlukeneyo.
Emva kokuba izinto zerabha zixutywe ngokulinganayo, irabha kufuneka ihluzwe ngesihluzo serabha ukuze kususwe ukungcola kwizinto zerabha. Emva koko sebenzisa ikhalenda, i-extruder, kunye nomatshini wokulamina ukuze wenze ifilimu okanye umcu ongenamaqamza kunye nokungcola kokwenza i-roller yerabha. Ngaphambi kokuba yenziwe, ezi filimu kunye nemicu yokuncamathelisa kufuneka zihlolwe ngokungqongqo ukubonakala ukuze kuncitshiswe ixesha lokupaka, kugcinwe umphezulu omtsha kwaye kuthintelwe ukunamathela kunye nokuguquguquka kwe-extrusion. Ngenxa yokuba uninzi lwee-roller zerabha ziimveliso ezingabumbekanga, xa kukho ukungcola kunye namaqamza kumphezulu werabha, amaqamza anokuvela xa umphezulu ucoliwe emva kokuguqulwa kwe-vulcanization, okuya kubangela ukuba yonke i-roller yerabha ilungiswe okanye ikhuhlwe.
