Kukana kwa dzimbiri kwa zida wamba valavu jjNatural rabara

Labala wachilengedwe

Labala wachilengedwe wa rabara ndi mtundu wachilengedwe wokhala ndi ma molekyulu ambiri okhala ndi polyisoprene monga gawo lalikulu. Mapangidwe ake a molekyulu ndi (c5h8) n. 91% ~ 94% ya zigawo zake ndi raba hydrocarbons (polyisoprene), ndipo zina zonse ndi zinthu zopanda mphira monga zomanga thupi, mafuta acid, phulusa, shuga, ndi zina zambiri. Labala wachilengedwe ndi mphira wogwiritsidwa ntchito kwambiri.

Kukana dzimbiri

Imakhala ndi elasticity yayikulu komanso pulasitiki pang'ono kutentha kwa chipinda, ndipo imawumitsa ndikuumitsa kutentha pang'ono. Ili ndi kukana bwino kwa alkali, koma osati kulimba kwa asidi. Sasungunuke m'madzi, ma ketoni otsika ndi ma alcohols, ndipo amatha kutupa muzosungunulira zopanda polar monga chloroform ndi carbon tetrachloride.
