Eminyakeni edlule, ukukhiqizwa kwama-roller enjoloba kwenze kwaba nzima ukwenza imishini kanye nokwenza izinto ngokuzenzakalela ngenxa yokungazinzi kwemikhiqizo kanye nokuhlukahluka kwemininingwane yosayizi. Kuze kube manje, iningi lawo lisasebenza ngesandla, liseyimigqa yokukhiqiza yokusebenza kweyunithi engaguquki. Muva nje, abanye abakhiqizi abakhulu abangochwepheshe sebeqalile ukukhiqiza okuqhubekayo kusukela ezintweni zerabha kuya ezinqubweni zokubumba kanye ne-vulcanization, okuphinde kabili ukusebenza kahle kokukhiqiza futhi kwathuthukisa kakhulu indawo yokusebenza kanye nokuqina kwabasebenzi.
Eminyakeni yamuva nje, ubuchwepheshe bokujova, ukukhipha kanye nokugoqa buthuthukiswe njalo, kanti imishini yokubumba kanye ne-vulcanization ye-rubber roller yenze ukukhiqizwa kwe-rubber roller kancane kancane kwaba ngomshini futhi kuzenzakalelayo. Ukusebenza kwe-rubber roller kunomthelela omkhulu kuwo wonke umshini, futhi kuqinile kakhulu ekusebenzeni kwenqubo kanye nekhwalithi yokukhiqiza. Imikhiqizo yayo eminingi ihlukaniswe njengemikhiqizo emihle. Phakathi kwayo, ukukhethwa kwezinto zerabha nezepulasitiki kanye nokulawulwa kokunemba kobukhulu bomkhiqizo kuyisihluthulelo. Ubuso berabha be-rubber roller abuvunyelwe ukuba nanoma yikuphi ukungcola, ama-blister nama-bubble, ingasaphathwa eyokuba nezibazi, amaphutha, imifantu, imifantu kanye neziponji zasendaweni kanye nezinye izinto ezithambile neziqinile. Ngenxa yalesi sizathu, i-rubber roller kumele ihlanzeke ngokuphelele futhi iqaphele kuyo yonke inqubo yokukhiqiza, ukuze kufezwe ukusebenza okuhlangene kanye nokuma okujwayelekile kobuchwepheshe. Inqubo yokuhlanganisa ipulasitiki yerabha kanye ne-metal core, ukunamathisela, ukubumba nge-injection, i-vulcanization kanye nokugaya isibe inqubo yobuchwepheshe obuphezulu.
Ukulungiswa kwerabha
Kuma-roller enjoloba, ukuxuba injoloba kuyisixhumanisi esibaluleke kakhulu. Kunezinhlobo ezingaphezu kweziyi-10 zezinto zerabha zama-roller enjoloba kusukela ku-raber yemvelo kanye nenjoloba yokwenziwa kuya ezintweni ezikhethekile. Okuqukethwe kwenjoloba kungu-25%-85%, kanti ubunzima bungamadigri enhlabathi (0-90), ahlanganisa ububanzi obubanzi. Ngakho-ke, indlela yokuxuba la ma-compounds ngokulinganayo isibe yinkinga enkulu. Indlela evamile ukusebenzisa umshini ovulekile wokuxuba nokucubungula ngendlela yama-master batches ahlukahlukene. Eminyakeni yamuva nje, izinkampani ziye zashintsha kakhulu ekuhlanganiseni ama-internal mixers ukuze zilungiselele ama-compound enjoloba ngokusebenzisa ukuxuba okuhlukaniswe ngezigaba.
Ngemva kokuba izinto zerabha zixutshwe ngokulinganayo, irabha kufanele ihlungwe ngesihlungi serabha ukuze kususwe ukungcola ezintweni zerabha. Bese usebenzisa ikhalenda, i-extruder, kanye nomshini wokulamina ukuze wenze ifilimu noma umugqa ongenamabhamuza nokungcola kokwakheka kwe-roller yerabha. Ngaphambi kokwakheka, la mafilimu kanye nemichilo yokunamathela kumele kuhlolwe ngokubukeka okuqinile ukuze kuncishiswe isikhathi sokupaka, kugcinwe indawo entsha futhi kuvinjelwe ukunamathela kanye nokuguquguquka kwe-extrusion. Ngenxa yokuthi iningi lama-roller erabha ayimikhiqizo engabunjiwe, uma sekukhona ukungcola namabhamuza ebusweni berabha, amabhamuza angavela lapho indawo igugulwa ngemuva kokubola, okuzokwenza ukuthi yonke i-roller yerabha ilungiswe noma ikhuhlwe.
