Amayunithi amaningi namafektri Sebenzisa abaxube abavulekile berabha. Isici salo esikhulu ukuthi inokuguquguquka okukhulu nokuhamba, futhi ilungele ikakhulukazi ukuxubana kokuhlukahluka okujwayelekile kwenjoloba, irabha elinzima, irabha le-sponge, njll.
Lapho uxubha nesigayo esivulekile, i-oda le-dosing libaluleke kakhulu. Ngaphansi kwezimo ezijwayelekile, irabha eluhlaza lifakwa kwi-roll gana eceleni kwesiphetho esisodwa sesondo elicindezelayo, futhi ibanga lokugoqa lilawulwa cishe ngo-2mm (thatha umxube werabha elingu-14 njengesibonelo se-5. I-glue eluhlaza yakhiwa kwifilimu ebushelelezi neyindilinga, esongelwe kwi-roller yangaphambili, futhi kunenani elithile le-glue eqoqiwe ku-roller. Ama-account aqoqiwe ama-akhawuntini acishe abe ngu-1/4 wenani eliphelele lerabha eluhlaza, bese kufakwa ama-anti-agents kanye nama-accelerators, futhi irabha lithambekele kaningana. Inhloso yalokhu ukwenza i-antioxidant kanye ne-accelerator ngokulinganayo bahlakazeke ngokulinganayo ku-glue. Ngasikhathi sinye, ukungezwa kokuqala kwe-antioxidant kungavimba into esezingeni eliphakeme esenzeka ngesikhathi sokushisa okushisa okuphezulu kwerabha. Futhi abanye ama-acceletors banomphumela weplastiki kwikhompiyutha yerabha. UZinc oxide bese wengezwa. Lapho ungeza i-carbon emnyama, inani elincane kakhulu kufanele lengezwe ekuqaleni, ngoba ezinye izibhamu eziluhlaza zizophuma ngokushesha lapho kufakwa i-carbon emnyama. Uma kukhona uphawu lwe-off-roll, yeka ukungeza ikhabhoni emnyama, bese ufaka ikhabhoni emnyama ngemuva kokuthi irabha lisongwe ngalo i-roller kahle futhi. Kunezindlela eziningi zokungeza ikhabhoni emnyama. Faka ikakhulukazi: 1. Faka i-carbon emnyama eceleni kobude be-roller; 2. Faka ikhabhoni emnyama maphakathi ne-roller; 3. Yengeze eduze kokuphela kokunye kwe-axamle. Ngokombono wami, lezi zindlela ezimbili zokungeza i-carbon emnyama zincama, okungukuthi, ingxenye kuphela ye-degumming isuswe ku-roller, futhi akunakwenzeka ukususa yonke i-roller. Ngemuva kokuthi i-rubber compound isuswe umqulu, i-carbon emnyama icindezelwa kalula emaflethini, futhi akulula ukuhlakazeka ngemuva kokusongelwa futhi. Ikakhulu uma ukhipha irabha kanzima, isibabule sicindezelwa emafulethini, okunzima kakhulu ukusabalalisa enjoloba. Futhi ukuguqula noma ukudlula okuncane kungashintsha indawo ephuzi "ephaketheni" elikhona kwifilimu. Ngamafuphi, lapho ungeza i-carbon emnyama, engeza okuncane futhi kaningi. Ungathathi inkathazo ukuthela yonke ikhabhoni emnyama ku-roller. Isigaba sokuqala sokungeza ikhabhoni emnyama isikhathi esisheshayo sokudla "sokudla". Ungangezi ukuthambisa ngalesi sikhathi. Ngemuva kokungeza ingxenye yekhabhoni emnyama, engeza uhhafu wethafa, ongasheshisa "ukondliwa". Enye ingxenye yethafa ingezwe ngekhabhoni esele emnyama. Enqubweni yokwengeza i-powder, ibanga le-roll kufanele livuseleleke kancane kancane ukugcina irabha elishumekiwe ngaphakathi kwebanga elifanele, ukuze i-powder ngokwemvelo ingena kwirabha futhi ingahlanganiswa nerabha kuze kube senjoloba. Kulesi sigaba, kunqatshelwe ngokuphelele ukusika ummese, ukuze kungathinti ikhwalithi yekhompiyutha yerabha. Endabeni ye-softener eningi kakhulu, ikhabhoni emnyama nethafa nayo ingangezwa ngendlela yokunamathisela. I-Stearic acid akufanele ingezwe kakhulu, kulula ukuyidala ukukhishwa, kungcono ukuyifaka lapho kusene-carbon emnyama emgodleni, futhi umenzeli we-vulcaning kumele futhi engezwe esiteji esizayo. Abanye abagqugquzeli be-polcaning nabo bangezwa lapho kusenekhabhoni encane emnyama ku-roller. Njenge-ejenti ye-ejenti DCP. Uma yonke i-carbon emnyama idliwa, i-DCP izofusheke yancibilika ibe nguketshezi, oluzowela emgqonyeni. Ngale ndlela, inani labamele ama-polcaning agents kwikhompiyutha lizoncishiswa. Ngenxa yalokhu, ikhwalithi yekhompiyutha yerabha iyathinteka, futhi kungenzeka ukuthi ibangele ubuvikeli be-undercoike. Ngakho-ke, umenzeli we-Vulcaning kufanele wengezwe ngesikhathi esifanele, kuya ngezinhlobonhlobo. Ngemuva kokuthi zonke izinhlobo zama-ejenti ahlanganisiwe zengezwa, kuyadingeka ukuqhubeka nokwenza i-rubber yahlanganisiwe ixutshwe. Imvamisa, kukhona "imimese eyisishiyagalombili", "izikhwama zoxantathu", "ukugoqa", "kuzithoba" nezinye izindlela zokujika.
"Imimese eyisishiyagalombili" yokusika imimese ku-angle engu-45 ° eceleni kwendlela efanayo ye-roller, amahlandla amane ohlangothini ngalunye. I-glue esele isontekile 90 ° futhi ingezwe ku-roller. Inhloso ukuthi impahla yerabha idluliswa izinkomba ezimile nezivundlile, ezilungele ukuxubana okufanayo. "Isikhwama sikanxantathu" yisikhwama sepulasitiki esenziwe ngonxantathu ngamandla we-roller. I- "Rolling" ukusika ummese ngesandla esisodwa, gingqa impahla yerabha kusilinda ngakolunye uhlangothi, bese uyifaka ku-roller. Inhloso yalokhu ukwenza ukuthi irakhe yerabha ixubene ngokulinganayo. Kodwa-ke, "isikhwama sonxantathu" kanye "nokugoqa" akusivumeli ekushisweni kokushisa kwezinto zenjoloba, okulula ukuzingela ukushelela, futhi kuyizinto ezinzima kakhulu, ngakho-ke lezi zindlela ezimbili akufanele zivunyelwe. Ukuguqula isikhathi esingu-5 kuye kwayi-6.
Ngemuva kokuthi irakhe yerabha iboshwe, kuyadingeka ukuncipha kwekhompiyutha yerabha. Ukuzijwayeza kufakazele ukuthi iphasi elincanyana elihlanganisiwe lisebenza kakhulu ekuhlakazeni kwe-ejenti ehlanganisiwe endaweni. Indlela edlula lapho ilungisa ibanga le-roller ku-0.1-0.5 mm, faka impahla yerabha ku-roller, bese uyivumela ukuba iwele kuthayela lokudla ngokwemvelo. Ngemuva kokuthi iwa, vula impahla yerabha ngo-90 ° ku-roller ephezulu. Lokhu kuphindaphinda izikhathi ezi-5 kuye kwezingu-6. Uma izinga lokushisa lendwangu enjoloba liphezulu kakhulu, yeka ukudlula okuncanyana, bese ulinda impahla yerabha ukuze ipholile ngaphambi kokuncipha ukuvikela impahla yerabha kusuka ekushiseni.
Ngemuva kokuthi ukudlula okuncane kuqediwe, phumula ibanga lokuqamba kuya ku-4-5mm. Ngaphambi kokulayishwa kwenjoloba emotweni, ucezu oluncane lwendwangu enjoloba lususiwe lubekwe kuma-roller. Inhloso ukubhoboza ibanga lokugoqa, ukuze uvikele umshini wokuxuba werabha kusuka ekuhlukunyezweni kwamandla amakhulu futhi ulimaze imishini ngemuva kwenani elikhulu lendwangu yerabha. Ngemuva kokulayishwa kwenjoloba emotweni, kufanele kudlule ku-roll gag kanye, bese uyisonga obala, qhubeka ukuwucisha imizuzu emi-2 kuya kwengama-3, bese uyela futhi uyipholile ngesikhathi. Ifilimu lingu-80 cm ubude, 40 cm ububanzi kanye no-0.4 cm obukhulu. Izindlela zokupholisa zifaka ukupholisa kwemvelo nokupholisa kwamanzi okubandayo, kuya ngemibandela yeyunithi ngalinye. Ngasikhathi sinye, kuyadingeka ukugwema ukuxhumana phakathi kwefilimu nenhlabathi, isihlabathi kanye nokunye ukungcola, ukuze kungathinti ikhwalithi yekhompiyutha yerabha.
Enqubweni yokuxuba, ibanga lokulingisa kufanele lilawulwe ngokuqinile. Izinga lokushisa elidingekayo ekuxubeni kwama-rubber ahlukene aluhlaza kanye nokuxutshwa kwamakhompiyutha ahlukahlukene ahlukahlukene ahlukile, ngakho-ke izinga lokushisa le-roller kufanele likwazi kahle ngokuya ngesimo esithile.
Abanye abasebenzi be-rubber ukuxuba abasebenzi banemibono emibili engalungile: 1. Bacabanga ukuthi isikhathi eside ukuxubana, kuphakama ikhwalithi yenjoloba. Lokhu akunjalo ekusebenzeni, ngenxa yezizathu ezichazwe ngenhla. 2. Kukholelwa ukuthi ngokushesha inani le-glue eliqongelelwe ngaphezulu kwe-roller elingeziwe, ngokushesha ijubane lokuxuba lizoba. Eqinisweni, uma kungekho glue eqoqiwe phakathi kwama-roller noma i-glue eqoqiwe incane kakhulu, i-powder izocindezelwa kalula ibe yi-flakes bese iwela ugqoko wokudla. Ngale ndlela, ngaphezu kokuthinta ikhwalithi yenjoloba ehlanganisiwe, kufanele kuhlanzwe ugqoko wokondla khona, futhi i-fall tow angezwa phakathi kwama-roller, aphindaphindwa kaningi, anweba kakhulu isikhathi sokuxuba futhi akhulisa amandla abasebenzi. Vele, uma ukunqwabelana kweglue kukhulu kakhulu, ijubane lokuxuba le-powder lizoncishiswa. Kungabonakala ukuthi ukunqwabelana okuncane kakhulu noma okuncane kakhulu kwe-glue akukufanele ukuxuba. Ngakho-ke, kufanele kube nenani elithile le-glue eqoqiwe phakathi kwama-roller ngesikhathi sokuxuba. Ngesikhathi sokuxinaka, ngakolunye uhlangothi, i-powder ifakwa kwi-glue ngesenzo samandla emishini. Ngenxa yalokho, isikhathi sokuxuba sifinyeziwe, ukuqina kwabasebenzi kuyancishiswa, futhi ikhwalithi yekhompiyutha yerabha ilungile.
