Emva kokuziqhelanisa, kusoloko kukho amaqamza emiphezulu yesampulu yerabha, eyahluka ngokwahluka. emva kokusika, kukho iibhubhu ezimbalwa kwisampulu .
Yenza uhlalutyo lwe-bubble kumphezulu weemveliso zerabha
1.}}}} irabha yerabha yerabha kunye nabasebenzi abangaqhelekanga .}
I-2, i-rubber yefilimu yefilimu ayikho {1. Ulawulo alunamgangatho .
3. umbandela u-suint (yongeza i-calcium oxide xa uxuba)
I-4, i-gocalcanization ayonelanga, hayi ipele ifana ne-bubble .
5.} uxinzelelo lonyango .
6, ukunyanga ukungcola kwe-arhente ngaphezulu, iimolekyuli ezincinci zokungcola zibe kukungasebenzi kwasekuqaleni, iimveliso ze-bubble
7. Uyilo oluninzi lwezinto ezinqabileyo alukho ngqiqweni, kwaye umoya awunakukhutshwa ngexesha apho irabha i-blankleng!
8. imveliso inzima kakhulu, irabha encinci yerabha, ukuveliswa kobushushu berabha, ukubonakala kwe-rubcan, ukuphangwa kwe-raber
9. irhasi engapheliyo ayikhutshwa kakuhle ngexesha lokuvuselelwa .
I-10, ingxaki yeFomula, inkqubo yobukumkani yokuphucula .
Isisombululo: Ukunyanga uxinzelelo kunye nexesha lokuphuculwa
1, Yandisa ixesha lokunyanga okanye ukuphucula isantya sokunyanga .
2.} amaxesha aliqela phambi kovumba .
I-3, i-vallializetion amaxesha amaninzi ngaphezulu .
