Ukuxuba kungenye yezinyathelo ezibaluleke kakhulu neziyinkimbinkimbi ekucutshungulweni kwerabha. Futhi kungenye yezinqubo ezivame kakhulu ukuguquguquka kwekhwalithi. Ikhwalithi yenhlanganisela yerabha ithinta ngqo ikhwalithi yomkhiqizo. Ngakho-ke, kubaluleke kakhulu ukwenza umsebenzi omuhle wokuxuba irabha.
Njengomxubi werabha, ungawenza kanjani umsebenzi omuhle wokuxuba irabha? Ngicabanga ukuthi ngaphezu kokuqonda kahle ulwazi oludingekayo lohlobo ngalunye lwerabha, njengezici zokuxuba kanye nokulandelana kokulinganisa, kubalulekile ukusebenza kanzima, ukucabanga kanzima, nokuxuba irabha ngenhliziyo. Kungale ndlela kuphela lapho kukhona umncibilikisi werabha ofaneleka kakhulu.
Ukuqinisekisa ikhwalithi yerabha exubile ngesikhathi senqubo yokuxuba, amaphuzu alandelayo kufanele enziwe:
1. Zonke izinhlobo zezithako ezinesilinganiso esincane kodwa umphumela omuhle kufanele zixutshwe ngokuphelele futhi zixutshwe ngokulinganayo, ngaphandle kwalokho kuzobangela ukusha kwerabha noma i-vulcanization engaphekiwe kahle.
2. Ukuxuba kufanele kwenziwe ngokuhambisana ngokuqinile nemithethonqubo yenqubo yokuxuba kanye nochungechunge lokudla.
3. Isikhathi sokuxuba kufanele silawulwe ngokuqinile, futhi isikhathi akufanele sibe side kakhulu noma sibe sifushane kakhulu. Kungale ndlela kuphela lapho ukuqina kwerabha exubile kungaqinisekiswa khona.
4. Ungalahli inani elikhulu le-carbon black kanye nama-filler, kodwa sebenzisa konke. Bese uhlanza ithileyi.
Yiqiniso, kunezici eziningi ezithinta ikhwalithi yerabha ehlanganisiwe. Kodwa-ke, izimpawu ezithile ukusabalala okungalingani kwe-combination agent, i-frost spray, i-scorch, njll., okungabonakala ngokubonakalayo.
Ukusabalala okungalingani kwe-compound agent Ngaphezu kwezinhlayiya ze-compound agent ebusweni be-compound yerabha, sika ifilimu ngommese, futhi kuzoba nezinhlayiya ze-compound agent ezinobukhulu obuhlukene engxenyeni ephambene ye-compound yerabha. I-compound ixutshwe ngokulinganayo, futhi ingxenye ibushelelezi. Uma ukusabalala okungalingani kwe-compound agent kungenakuxazululwa ngemva kokucwengisiswa okuphindaphindiwe, i-roller rubber izolahlwa. Ngakho-ke, i-rubber mixer kumele ilandele ngokuqinile imithetho yenqubo ngesikhathi sokusebenza, futhi ngezikhathi ezithile, thatha ifilimu kuzo zombili izinhlangothi naphakathi kwe-roller ukuze ubone ukuthi i-compound agent ihlakazeke ngokulinganayo yini.
Ukuqandisa, uma kungeyona inkinga yokwakheka kwefomula, khona-ke kubangelwa ukuhleleka okungafanele komthamo ngesikhathi senqubo yokuxuba, noma ukuxuba okungalingani kanye nokuhlanganiswa kwe-compound agent. Ngakho-ke, kubalulekile ukulawula ngokuqinile inqubo yokuxuba ukuze kugwenywe ukwenzeka kwezehlakalo ezinjalo.
I-Scorch ingenye yezinkinga ezibaluleke kakhulu enqubweni yokuxuba. Ngemva kokuba izinto zerabha zishisiwe, ubuso noma ingxenye yangaphakathi inezinhlayiya zerabha eziphekiwe ezithambile. Uma i-scorch incane, ingaxazululwa ngendlela yokudlula okuncane. Uma i-scorch inzima, izinto zerabha zizolahlwa. Ngokombono wezinto zenqubo, i-scorch ye-compound yerabha ithintwa kakhulu yizinga lokushisa. Uma izinga lokushisa le-compound yerabha liphezulu kakhulu, i-raber eluhlaza, i-agent ye-vulcanizing kanye ne-accelerator zizosabela ngesikhathi senqubo yokuxuba, okungukuthi, i-scorch. Ngaphansi kwezimo ezijwayelekile, uma inani lerabha ngesikhathi sokuxuba likhulu kakhulu futhi izinga lokushisa le-roller liphezulu kakhulu, izinga lokushisa lerabha lizokhuphuka, okuholela ekushiseni. Vele, uma ukulandelana kokudla kungafanele, ukungezwa ngasikhathi sinye kwe-agent ye-vulcanizing kanye ne-accelerator nakho kuzobangela kalula ukushiswa.
Ukuguquguquka kobulukhuni nakho kuyisici esibalulekile esithinta ikhwalithi yenhlanganisela yerabha. Ama-compound anobulukhuni obufanayo avame ukuhlanganiswa nobunzima obuhlukene, futhi amanye aqhelelene kakhulu. Lokhu kungenxa kakhulu yokuxubana okungalingani kwenhlanganisela yerabha kanye nokuhlakazeka okubi kwe-ejenti ehlanganisayo. Ngesikhathi esifanayo, ukwengeza i-carbon black encane noma ngaphezulu kuzophinde kubangele ukuguquguquka kobulukhuni benhlanganisela yerabha. Ngakolunye uhlangothi, isisindo esingafanele se-ejenti ehlanganisayo sizophinde sibangele ukuguquguquka kobulukhuni benhlanganisela yerabha. Njengokungezwa kwe-ejenti evulcanizing kanye ne-accelerator carbon black, ubulukhuni benhlanganisela yerabha buzokwanda. I-softener kanye nerabha eluhlaza kuyakalwa kakhulu, kanti i-carbon black incane, kanti ubulukhuni benhlanganisela yerabha buyancipha. Uma isikhathi sokuxuba side kakhulu, ubulukhuni benhlanganisela yerabha buzoncipha. Uma isikhathi sokuxuba side kakhulu, ubulukhuni benhlanganisela yerabha buzoncipha. Ngakho-ke, isikhathi sokuxuba akufanele sibe side kakhulu noma sifushane kakhulu. Uma ukuxuba kukude kakhulu, ngaphezu kokuncipha kokuqina kwerabha, amandla okudonsa erabha azoncipha, ukunwebeka ngesikhathi sokuphumula kuzokwanda, kanye nokumelana nokuguga kuzoncipha. Ngesikhathi esifanayo, kwandisa namandla okusebenza kwabasebenzi futhi kudla amandla.
Ngakho-ke, ukuxuba kudinga kuphela ukukwazi ukusabalalisa ngokuphelele izinto ezahlukahlukene zokuhlanganisa enkomponini yerabha, nokuqinisekisa izakhiwo zomzimba nezomshini ezidingekayo kanye nezidingo zokucubungula, ukukhipha kanye neminye imisebenzi yenqubo.
Njengomxubi werabha ofanelekayo, akagcini nje ngokuba nomuzwa oqinile womthwalo wemfanelo, kodwa futhi kumelwe ajwayelane namarabha angahluziwe ahlukahlukene nezinto zokusetshenziswa. Okusho ukuthi, hhayi nje ukuqonda imisebenzi nezakhiwo zawo, kodwa futhi nokukwazi ukubiza amagama awo ngokunembile ngaphandle kwamalebula, ikakhulukazi ama-compounds anokubukeka okufanayo. Isibonelo, i-magnesium oxide, i-nitric oxide kanye ne-calcium hydroxide, i-carbon black engagugi kakhulu, i-carbon black ekhishwa ngokushesha kanye ne-carbon black eqinisiwe kancane, kanye ne-nitrile-18 yasekhaya, i-nitrile-26, i-nitrile-40 njalo njalo.
