Zenzelweni izinwele zamasondo? Iqiniso liwukuthi, azinamsebenzi. Noma kunjalo, cishe wonke amathayi anabo lobu boya ekhejini lawo. Kodwa uma zingasizi, kungani zikhona?
nezindaba zokukhiqiza
Lezi zinwele zibangelwa ukweqisa kwerabha ephuma esikhunjeni ngesikhathi sokwenziwa, lapho isondo lingaphansi kwengcindezi ephezulu ukuze lithole ukuma kwalo kokugcina. Lesi sikhunta sinezimbobo ezincane ezinomsebenzi wokukhipha umoya owedlulele futhi ovumela irabha ukuthi ithole umumo ovela esikhunjeni.
Buka ividiyo:
Kukhona izinhlobo ezikhetha ukuthengisa amathayi namanje nalezi zinwele, ezinye izinhlobo ziyawasika. Namuhla, uboya bamathayi, ngokombono ojwayelekile wabathengi, buyisici esingenakuhlukaniswa samathayi amasha.
Akuyona nje indaba yefomu.
Akukhona nje ukuthola isimo sokugcina lapho irabha yesondo - kungakhathaliseki ukuthi yokwenziwa noma yemvelo - ingaphansi kwengcindezi ephezulu. Amathayi abhekana nalokhu kwelashwa ukuze irabha nezingxenye ezihlukahlukene eziyakhayo zihlangane. Le nqubo yamakhemikhali ibizwa ngokuthi i-vulcanization. Yile nqubo eyenza irabha izimfanelo zayo ezinwebekayo.
Sihlala sifunda. Sesikuchazile ukuthi uyifunda kanjani yonke imininingwane equkethwe ethayini, nokuthi kukhona amathayi anemininingwane ethile yemoto yakho, kepha kukhona ezinye izinto ezithokozisayo. Maduze buya kule timu. Phela, iyona kuphela into yemoto ethintana ne-asphalt.
