pvc resin mo ata tifaga malo
pvc resin mo ata tifaga malo,
PVC resini ata tifaga vasega, PVC resin mo ata tifaga, PVC resin mo ata tifaga manino,
Rigid PVC FIlms ose mea fa'apipi'i tele e fa'aogaina mo fa'apipi'i mea eseese.O le oloa e faigofie ona faʻaoga e pei o isi mea palasitika… o ona uiga e pei o le manino, faʻaogaina i le maualalo o le vevela, faigofie ona lolomi e avea o se oloa e faʻaogagofie.
Mo le gaosiga ma le faʻaaogaina o le PVC ata tifaga manino maaa, o le resin o loʻo faʻaalia i le tufatufaina vaapiapi o resin polymerization tikeri e faʻamautinoa ai le lelei o le plasticizing faʻatinoga ma le lelei o mea tau masini. .
Polyvinyl chloride (PVC) resin o se polymer maualuga e gaosia e le polymerization o le ethylene.O le polymerization fa'agata o lo'o fa'aaogaina e fai ma auala masani o le polymerization tau alamanuia.E masani lava o se malo e mafai ona faamaluluina e ala i le faamafanafanaina.Pe a vevela, e masani lava ona i ai le vevela o le faʻafefeteina poʻo le faʻamaluluina, ma e mafai ona i ai i se tulaga tafe palasitika i lalo o le gaioiga a le malosi mai fafo.E mafai e le fale gaosi oloa ona faʻaopoopo le plasticizer poʻo isi ausilali e faʻafetaui manaoga o le gaosiga e tusa ai ma manaʻoga faʻatinoga o oloa palasitika.
Vasega S-1300 e masani lava ona faʻaaogaina e gaosia ai oloa faʻafefeteina maualuga-malosi, mea faʻapipiʻi, maʻaʻa ma fetuutuunai extrusion molding ma mea insulating, ma isi. E pei o ata manifinifi, ipu manifinifi, paʻu faafoliga, uaea, uaea faaofuofu ma vaivai ituaiga uma o talaaga otooto.
