isicelo

Ukwakhiwa okuphambili kwezinto zentambo yePVC ikakhulu kubandakanya:polyvinyl chloride resin, i-dioctyl phthalate, i-stabilizer, i-plasticizer, i-inorganic filler, i-filler, i-lubricant, i-antioxidant, i-colorant, njl., elungiselelwe ngokuxuba kunye nokuxova kunye nokukhupha.

Umxholo wePlastiki uhlala phakathi kwe-50PHR kunye ne-60PHR.Rhoqo khetha ukumelana nobushushu kunye nokusebenza kokufakelwa kombane kweplasticizer ebalaseleyo ukuze kuphuculwe ngcono ukumelana nobushushu kunokongezwa kwi-trioctyl metapentriacid.Iindidi zeplastiki ezisetyenziswa kunye zihlala zinesiphumo esihle.Enyanisweni, iiplasticizers kwi-PVC cable material formula nazo zisetyenziswa kunye.Izinto zentambo ze-PVC ezinokwaleka okuqinileyo zingakhetha i-phosphate ester njenge-arhente ephambili, kunye ne-benzoate ester njenge-arhente ephambili ifanele ibakala ngokubanzi.Ukuxhathisa ubushushu kunye nokuxhathisa okuguquguqukayo kwe-plasticizer zizinto ezithatha isigqibo sokumelana nobushushu obuphezulu bezinto zekhebula.
