Jiid Jiid Jiid ah

Jiidka daahista caagga ah waa in lagu daboolo lakabka caagga dushiisa ee durbaanka birta iyadoo la adeegsanayo vulcanization kulul ama habka qaboojinta, kaas oo loo isticmaalo in lagu yareeyo xirashada birta iyo ilaalinta si loo kordhiyo nolosha adeegga suunka qaada.

Faahfaahinta

Noocyada caagga ah ee loo isticmaali karo in lagu daboolo durbaanka waa: NBR, CR, HYPLON, PU, SBR, SR, iyo wixi la mid ah. Kaas oo lagu beddeli karo si waafaqsan alaabtaada iyadoo la adeegsanayo jawiga iyo shuruudaha naqshadeynta alaabta.

Alaabta Halbeegyada

Halbeegyada waxqabadka caagga guud sida soo socota:
