Ukuxuba kungenye yezinyathelo ezibaluleke kakhulu neziyinkimbinkimbi ekucubunguleni irabha.Futhi kungenye yezinqubo ezivame kakhulu ekuguquguqukeni kwekhwalithi.Izinga le-compound yerabha lithinta ngqo ikhwalithi yomkhiqizo.Ngakho-ke, kubaluleke kakhulu ukwenza umsebenzi omuhle wokuxuba i-rubber.
Njengomxube wenjoloba, ungawenza kanjani umsebenzi omuhle wokuxuba iraba?Ngicabanga ukuthi ngaphezu kokubamba kahle ulwazi oludingekayo lohlobo ngalunye lwenjoloba, njengezici zokuxuba nokulandelana kwemithamo, kuyadingeka ukusebenza kanzima, ukucabanga kanzima, nokuxuba injoloba nenhliziyo.Kungale ndlela kuphela isincibilikisi senjoloba esifaneleke kakhulu.
Ukuqinisekisa ikhwalithi yerabha exutshwe ngesikhathi sokuxuba, amaphuzu alandelayo kufanele enziwe:
1. Zonke izinhlobo zezithako ezinomthamo omncane kodwa umphumela omkhulu kufanele zixutshwe ngokugcwele futhi zixutshwe ngokulinganayo, ngaphandle kwalokho kuzobangela ukushisa kwerabha noma ukuvuthwa okungaphekiwe.
2. Ukuxuba kufanele kwenziwe ngokuhambisana ngokuqinile nemithetho yenqubo yokuxuba kanye nokulandelana kokuphakelayo.
3. Isikhathi sokuxuba kufanele silawulwe ngokuqinile, futhi isikhathi akufanele sibe side kakhulu noma sifushane kakhulu.Kungale ndlela kuphela lapho ipulasitiki yenjoloba exubile ingaqinisekiswa.
4. Ungalahli inani elikhulu lekhabhoni emnyama kanye nezigcwalisi, kodwa zisebenzise.Bese uhlanza ithreyi.
Yiqiniso, kunezici eziningi ezithinta ikhwalithi yenjoloba ehlanganisiwe.Kodwa-ke, ukubonakaliswa okuqondile ukuhlakazeka okungalingani kwe-ejenti ehlanganisayo, isifutho se-frost, ukushisa, njll, okungabonwa ngokubuka.
Ukuhlakazwa okungalingani kwe-agent ehlanganisayo Ngaphezu kwezinhlayiya ze-ejenti ehlanganisiwe ebusweni be-raber compound, usike ifilimu ngommese, futhi kuzoba nezinhlayiya ze-agent ezihlanganisayo ezinobukhulu obuhlukene engxenyeni ye-rubber compound.I-compound ixubene ngokulinganayo, futhi isigaba sibushelelezi.Uma ukuhlakazeka okungalingani kwe-ejenti ehlanganisayo akukwazi ukuxazululwa ngemva kokucwengwa okuphindaphindiwe, irabha ye-roller izochithwa.Ngakho-ke, i-mixer yenjoloba kufanele ihambisane ngokuqinile nemithethonqubo yenqubo ngesikhathi sokusebenza, futhi ngezikhathi ezithile, thatha ifilimu kusuka kuzo zombili iziphetho naphakathi kwe-roller ukuze ibone ukuthi i-ejenti ehlanganisiwe ihlakazekile ngokulinganayo.
I-Frosting, uma kungeyona inkinga yokuklama ifomula, khona-ke kubangelwa ukuhleleka okungalungile kokudosa ngesikhathi senqubo yokuxuba, noma ukuxuba okungalingani kanye ne-agglomeration ye-ejenti ehlanganisiwe.Ngakho-ke, kuyadingeka ukulawula ngokuqinile inqubo yokuxuba ukuze ugweme ukuvela kwezimo ezinjalo.
I-Schorch ingenye yezinkinga ezibaluleke kakhulu ohlelweni lokuxuba.Ngemva kokuba impahla yenjoloba ishisiwe, ingaphezulu noma ingxenye yangaphakathi inezinhlayiya zenjoloba eziphekiwe ezinwebekayo.Uma i-scorch incane, ingaxazululwa ngendlela encane yokudlula.Uma ukushisa kubi kakhulu, izinto zenjoloba zizolahlwa.Ngokombono wezici zenqubo, ukushisa kwenhlanganisela yenjoloba kuthinteka kakhulu izinga lokushisa.Uma izinga lokushisa le-rubber compound liphezulu kakhulu, i-rubber eluhlaza, i-vulcanizing agent kanye ne-accelerator izosabela ngesikhathi senqubo yokuxuba, okungukuthi, ukushisa.Ngaphansi kwezimo ezijwayelekile, uma inani lerabha ngesikhathi sokuxuba likhulu kakhulu futhi izinga lokushisa le-roller liphezulu kakhulu, izinga lokushisa le-rubber lizokwanda, okuholela ekushiseni.Vele, uma ukulandelana kokuphakelayo kungalungile, ukungezwa kanyekanye kwe-ejenti evuzayo kanye ne-accelerator nakho kuzodala ukushisa.
Ukushintshashintsha kokuqina nakho kuyisici esibalulekile esithinta ikhwalithi yenhlanganisela yerabha.Izithako zokuqina okufanayo zivame ukuxutshwa nobulukhuni obuhlukene, kanti ezinye ziqhelelene kakhulu.Lokhu kubangelwa ikakhulukazi ukuxuba okungalingani kwenhlanganisela yenjoloba kanye nokuhlakazeka okubi kwe-ejenti ehlanganisayo.Ngesikhathi esifanayo, ukwengeza i-carbon black encane noma ngaphezulu kuzophinde kubangele ukushintshashintsha kokuqina kwe-rubber compound.Ngakolunye uhlangothi, ukukala okungalungile kwe-ejenti ehlanganisiwe kuzophinde kubangele ukushintshashintsha kokuqina kwenhlanganisela yerabha.Njengokwengezwa kwe-ejenti ye-vulcanizing kanye ne-accelerator carbon black, ubulukhuni be-compound yerabha buzokhula.I-softener nerabha eluhlaza kukalwa ngaphezulu, futhi i-carbon black incane, futhi ukuqina kwenhlanganisela yerabha kuba kuncane.Uma isikhathi sokuxuba side kakhulu, ubulukhuni be-rubber compound buzokwehla.Uma isikhathi sokuxuba sisifushane kakhulu, inhlanganisela izoqina.Ngakho-ke, isikhathi sokuxuba akufanele sibe side kakhulu noma sibe sifushane kakhulu.Uma ukuxuba kukude kakhulu, ngaphezu kokuncipha kokuqina kwerabha, amandla aqinile werabha azokwehla, ukuphakama ngesikhathi sekhefu kuzokwanda, futhi ukumelana nokuguga kuzokwehla.Ngesikhathi esifanayo, kwandisa amandla okusebenza kwabaqhubi futhi kudla amandla.
Ngakho-ke, ukuxuba kudinga kuphela ukukwazi ukusabalalisa ngokugcwele ama-ejenti ahlukahlukene ahlanganisayo ku-compound yenjoloba, nokuqinisekisa izakhiwo ezidingekayo zomzimba nemishini kanye nezidingo ze-calendering, i-extrusion kanye neminye imisebenzi yenqubo.
Njengomxube wenjoloba oqeqeshiwe, akagcini nje ngokuba nomuzwa oqinile womthwalo wemfanelo, kodwa futhi kufanele ajwayelane namarabha ahlukahlukene aluhlaza nezinto zokusetshenziswa.Okungukuthi, hhayi kuphela ukuqonda imisebenzi yabo kanye nezakhiwo, kodwa futhi bakwazi ukuqamba ngokunembile amagama abo ngaphandle kwamalebula, ikakhulukazi ama-compounds anokubukeka okufanayo.Isibonelo, i-magnesium oxide, i-nitric oxide ne-calcium hydroxide, i-carbon black resistant high, i-carbon black extrusion esheshayo ne-semi-reinforced carbon black, kanye ne-nitrile-18 yasekhaya, i-nitrile-26, i-nitrile-40 njalonjalo.
