Kwinkqubo yokwenza intlama, izihluzi ezahlukahlukeneyo, i-diluents, i-stabilizers yokushisa, i-agent e-foaming kunye ne-stabilizers yokukhanya yongezwa ngokwe ... -
Yintoni iifilimu zePP?
I-PROPERTIES I-Polypropylene okanye i-PP yindleko ephantsi ye-thermoplastic yokucaca okuphezulu, i-gloss ephezulu kunye namandla asebenzayo. Inomlinganiselo ophezulu wokunyibilika kune-PE, eyenza ukuba ifaneleke kwizicelo ezifuna inzala kumaqondo obushushu aphezulu. Ikwanayo nenkungu encinci kunye neglosi ephezulu. Ngokubanzi, iimpawu zokutywinwa kobushushu zePP azilunganga njengezo ze-LDPE. I-LDPE ikwanamandla angcono okukrazula kunye nokumelana nefuthe lobushushu obuphantsi. I-PP inokuthi yenziwe ngetsimbi ekhokelela ekuphuculweni kweepropati zokuthintela igesi kwizicelo ezifunwayo apho ixesha elide leshelufu libalulekile. Iifilimu ze-PP zifaneleke kakuhle uluhlu olubanzi lwemizi-mveliso, abathengi, kunye nosetyenziso lweemoto. I-PP inokuphinda isetyenziswe ngokupheleleyo kwaye inokuphinda ihlaziywe ngokulula kwezinye iimveliso ezininzi ezahlukeneyo zosetyenziso. Nangona kunjalo, ngaphandle ... -
yintoni iPVC compound?
Iikhompawundi ze-PVC zisekelwe kwindibaniselwano ye-PVC ye-polymer RESIN kunye nezongezelelo ezinikezela ukuqulunqwa okuyimfuneko ekusetyenzisweni kokuphela (Imibhobho okanye iiProfayili eziqinileyo okanye iiProfayili eziguquguqukayo okanye iiSheets). Ikhompawundi yenziwe ngokuxuba ngokusondeleyo kunye nezithako, ezithi emva koko ziguqulelwe kwinqaku elithi "gelled" phantsi kwefuthe lobushushu kunye ne-shear force. Ngokuxhomekeke kuhlobo lwe-PVC kunye nezongezelelo, i-compound phambi kwe-gelation ingaba yi-powder-flowing powder (eyaziwa ngokuba ngumxube owomileyo) okanye i-liquid ngendlela ye-paste okanye isisombululo. Iikhompawundi zePVC xa zenziwe, kusetyenziswa iiplastiki, zibe yimathiriyeli ebhetyebhetye, edla ngokubizwa ngokuba yiPVC-P. I-PVC Compounds xa yenziwe ngaphandle kwe-plasticizer kwizicelo eziqinileyo zityunjwe i-PVC-U. I-PVC Compounding inokushwankathelwa ngolu hlobo lulandelayo: I-PVC eqinile dr ... -
Umahluko phakathi kweBOPP, i-OPP kunye nePP Bags.
Ishishini lokutya ikakhulu lisebenzisa ukupakishwa kweplastiki yeBOPP.
