I-white carbon black iyisengezo esimhlophe esingaxubile esinezakhiwo ezithile zokuqinisa, esingathatha indawo ye-carbon black ukuze siqinise izinto zerabha ekukhiqizweni kwemikhiqizo yerabha, ikakhulukazi imikhiqizo yerabha emhlophe, ekhanyayo noma enemibala. Ukusetshenziswa kwe-white carbon black ekukhiqizweni kwamathayi angaphandle komgwaqo, amathayi obunjiniyela, amathayi e-radial, njll. kunomphumela wokuthuthukisa ukusebenza okuphelele kwamathayi ezimoto nokwandisa ibanga lamathayi. Ngakho-ke yimiphi imisebenzi ethile ye-white carbon black emathayini erabha, futhi yini okufanele inakwe lapho kusetshenziswa i-white carbon black ekukhiqizweni kwamathayi?
1. Indima yomnyama omhlophe wekhabhoni emathayini
Ukwengeza umnyama wekhabhoni omhlophe ekukhiqizweni kwamathayi kunganciphisa ukumelana nokugoqa amathayi, kunciphise ukusetshenziswa kukaphethiloli, futhi kuthuthukise kakhulu ukumelana nokushelela kwamathayi kanye nokusebenza kokuphepha. Ucwaningo lukhombisile ukuthi ukufaka esikhundleni umnyama wekhabhoni omhlophe nge-black yekhabhoni omhlophe kunganciphisa ngempumelelo umphumela we-Paine wezinto zerabha, kanye ne-angle tangent tan yokulahlekelwa emazingeni okushisa aphezulu δ， Ngaleyo ndlela kuthuthukiswe ukumelana nokugoqa kwamathayi. Ukusetshenziswa kwayo yonke inhlanganisela ye-white carbon black tread kunganciphisa ukumelana nokugoqa ngo-20% kanye nokusebenza kokugoqa kwamathayi cishe ngo-50%, ngaleyo ndlela konge uphethiloli ongaphezu kuka-3%.
Ngemva kokufaka umnyama omhlophe wekhabhoni kufomula yokunyathela ithayi, izakhiwo ezahlukahlukene zethayi ziyathuthukiswa kakhulu; Ikakhulukazi ekulinganisweni kokumelana nokuguguleka kwethayi, ukubamba okumanzi, kanye nokumelana nokugingqika.
2. Ukusetshenziswa okwanele kwekhabhoni emhlophe emnyama emathayini
Uma i-carbon black emhlophe isetshenziselwa ukuqinisa amathayi enjoloba, ngenxa yendawo yayo encane yokuxhumana, ukusondelana kwayo nenjoloba kuyabi kahle; Kulula ukuhlangana, akuhambisani nokuhlakazeka ngesikhathi sokuxuba; Ngesikhathi senqubo yokuhlanganisa, kuba nomphumela we-vulcanization obambezelekile, ongasabela kalula nezinye izingxenye. I-carbon black emhlophe ithambekele ekumunceni ezinye izinto zokuxhumanisa, okungahambisani nokuhlakazeka; Kulula ukumunca amanzi bese kwakha amaqembu e-silicon oxide, okungahambisani nokunamathelana; Ukuqina kwesakhiwo kuholela ekwandeni kwe-viscosity ngesikhathi sokugcina. Ngakho-ke, abakhiqizi bamathayi kufanele bathathe izinyathelo ezithile zokuthuthukisa umphumela wokusetshenziswa kwe-carbon black emhlophe lapho beyisebenzisa.
3. Izindlela zokuthuthukisa umphumela wokufaka umnyama omhlophe wekhabhoni emathayini
Ekukhiqizweni kwangempela, ukusetshenziswa kweziguquli kungalungisa umphumela wokwengeza we-white carbon black emathayini, kanye nama-coupling agents njengewona ayinhloko, kanti ama-silane coupling agents asetshenziswa kakhulu kuma-coupling agents. Iqembu le-siloxy kuma-silane coupling agents linokusabela kwezinto ezingaphili, kuyilapho iqembu elisebenzayo le-organic linokusabela noma ukuhambisana nezinto eziphilayo. Lapho i-silane coupling agent iphakathi kwe-inorganic interfaces kanye ne-organic, ungqimba olubophayo lwe-organic matrix silane coupling agent matrix inorganic lungakhiwa.
Ukwengeza inani elifanele le-ejenti yokuxhumanisa i-silane kufomula yethayi eqiniswe nge-silica kungakha ngempela isibopho esiqinile phakathi kwama-molecule e-elastomer ne-silica, kuthuthukise kakhulu ukunwebeka lapho kuphuka futhi kumelana nokudabuka, futhi kufinyelele ukusebenza okuphansi kwe-hysteresis.
Ekukhiqizeni kwangempela, abakhiqizi bamathayi erabha bangasebenzisa futhi i-white carbon black ehlakazekile kakhulu. I-white carbon black ehlakazekile kakhulu ayikwazi nje ukuqinisekisa kangcono ukumelana nokushelela okumanzi kanye nokumelana okuphansi kokugingqika kwamathayi, kodwa futhi ithuthukise ukusebenza kokuguguleka nokusebenza kwezinto zerabha. Njengamanje, izinqubo eziningi zokukhiqiza amathayi zisebenzisa irabha ephinde yasetshenziswa. Nginethuba lokwabelana nawe ngamathiphu okusebenzisa i-white carbon black ezintweni zamathayi eziqukethe irabha ephinde yasetshenziswa.
