yintoni i-PVC compound?
Iikhompawundi zePVC zisekelwe kudibaniso lwe-PVC polymer RESIN kunye nezongezo ezinika ifomula efunekayo ekusetyenzisweni kokugqibela (iiPipes okanye iiRigid Profiles okanye iiFlexible Profiles okanye iiSheets). Le khompawundi yenziwa ngokudibanisa ngokusondeleyo izithako, ezithi kamva ziguqulwe zibe yinto "efakwe ijeli" phantsi kwempembelelo yobushushu kunye namandla okucheba. Ngokuxhomekeke kuhlobo lwePVC kunye nezongezo, ikhompawundi ngaphambi kokufakwa ijeli inokuba yipowder ehamba ngokukhululekileyo (eyaziwa ngokuba yi-dry blend) okanye ulwelo ngendlela ye-paste okanye isisombululo. Iikhompawundi zePVC xa zenziwe, kusetyenziswa iiplasticizers, zibe zizinto eziguquguqukayo, ezidla ngokubizwa ngokuba yiPVC-P. Iikhompawundi zePVC xa zenziwe ngaphandle kweplasticizer yokusetyenziswa okuqinileyo zibizwa ngokuba yiPVC-U. I-PVC Compounding ingashwankathelwa ngolu hlobo lulandelayo: I-PVC dr... -
Umahluko phakathi kweengxowa zeBOPP, OPP kunye nePP.
Ishishini lokutya lisebenzisa kakhulu iipakethe zeplastiki zeBOPP. Iingxowa zeBOPP kulula ukuziprinta, ukuzigquma kunye nokuzifaka ilaminethi nto leyo eyenza ukuba zilungele ukupakisha iimveliso ezifana neemveliso ezintsha, iilekese kunye nezidlo.
