Lokhu iraba eluhlaza okunokwethenjelwa futhi enza izinto ezihlukahlukene

kusukela esikhathini samakhosi Rubber waziwa kokutholakala Melika uColumbus. AmaNdiya wasebenzisa ubisi Milky injoloba isihlahla Hevea bonyana batshidze ezinzulwini ezikebheni, ukudala izitsha, nezicathulo manzi, kanye womshini amabhola. Kodwa eYurophu okwesikhathi eside isikhathi amathayi kabanzi (kufika ku ngekhulu XIX). Futhi sonke ngoba iraba eluhlaza ngokuhamba kwesikhathi zome futhi ibe lukhuni. Inqubo okusungulile ibuyisela iraba izakhiwo kokuqala kanye kwezinga lokushisa lamanzi sinjalo wadala boom yangempela womshini izihloko zenjoloba.

Njengoba iraba-ipulazi alidalule nesidingo esikhulayo kancane kancane, ngokuhamba kwesikhathi, bakhula indlela yokuthola iraba zokwenziwa, okuyinto nanamuhla. Esikhathini yesimanje izinsimbi compounds iraba iraba eluhlaza. Njengoba injalo iluhlaza isetshenziswa womshini imikhiqizo ehlukahlukene, njengoba umthetho - kubekwe uphawu futhi ukulungisa imoto amathayi amakhamera indlela esishisayo (elapha). Kusukela Izingxube ukunikeza ezihlukahlukene imikhiqizo asetshenziswa cishe yonke imikhakha. Bobabili omunye nezinye izinto ayatholakala ngesimo amashidi noma strip okuqhubekayo (iwebhu). Ukuqokwa bona zingase zishintshe kakhulu - ezempilo, ukudla, Kwe-dielectric Heating, uwoyela nemithi, njll

Ukusetshenziswa iraba zokusetshenziswa for silungisa amathayi

Abashayeli avame ukubhekana amacala umonakalo mechanical kuya isondo (kanye amakhamera). Ezimweni eziningi, isondo ezilimele kungenziwa lilungiswe. Lokhu kungenziwa kokubili iqine abandayo futhi kushisa. Cold wenziwa usebenzisa Ukwakheka ekhethekile (butyl Activator ungqimba), kanye vulcanisation ashisayo - iraba ongahluziwe.

Izingxenye kwakwakhe iraba nge iqine abandayo wenziwa ngaphandle kokwelashwa ukushisa. Le ndlela ithatha isikhathi eside futhi kudinga ukunamathela ngokuqinile ubuchwepheshe aqine. Ukuphulukiswa Zezıhlabane engenziwa zonke, kuhlanganise nasensimini, izimo. Lokhu kudinga kuphela iraba eluhlaza kanye vulcanizer. Ukuphulukiswa kungenzeka umile, ephathekayo (ebalekela 220) kanye ephathekayo (imoto esebenza inethiwekhi).

Indlela yokusebenzisa irabha eluhlaza ngesikhathi iqine

Okokuqala, endaweni ezilimele kufanele kahle bahlanza of ukungcola, aphathe lokukhuhla futhi degrease. Khona-ke kudingeka sigqoke isichibi ukusika iraba ongahluziwe futhi ibekwe endaweni vulcanizer. Ukuvimbela adhesion phakathi patch kanye Ukushisa element uqobo ephepheni izindlu.

iraba ongahluziwe libukeka uhlobo ingxube plastic, okuyinto, lapho iqine lingena ngokwanele ngokujulile phakathi lesion futhi ngokuphephile ishumeka ke. Lapho ukufuthelana, kuba namandla, kodwa uhlala nezimo. Amazinga lapho sokwelapha kwenzeka imayelana 140-160 ° ^C. Lapho ufika kule lokushisa (kunqunywa ushintsho umbala iphepha) vulcanizer inqanyuliwe. Uma umkhiqizo is selehlile ngokuphelele, ilungele ukusetshenziswa eminye.

Akunconyelwe Gwema aphakeme okushisa phezu 160 ^{° C,} njengoba lokhu kuholela desiccation ngerabha futhi, ngenxa yalokho - ekulahlekelweni kuyaqina.
