PVC K tau 57
PVC K tau 57,
PVC resin fa'aaogaina e gaosia ai laupapa foam,
O le PVC resin faʻatasi ma le K tau o le 55-68 e mafai ona faʻaaogaina e gaosia ai le foam malosi, o lona uiga, faʻamalosi PVC oloa maualalo-foam, e ese mai le tau K o loʻo tuʻuina atu i faʻamatalaga ua mavae ma tusi.PVC resins ma K tau o le 69-77 ua faʻaalia e fetaui lelei mo le gaosiga o fofo vaivai.E tele auala e gaosia ai le PVC resin, auala faʻamalolo, auala emulsion ma le tele o le polymerization o le PVC resin o loʻo maua mea mataʻutia mo oloa foamed, e masani ona faʻamalolo ma le tele polymerization o PVC resin e talafeagai.PVC copolymers ma fa'apipi'i polymers (granular polymers) e lelei fo'i le fa'agaioiina ma e seasea fa'aaogaina ona o tau.
O le Polyvinyl Chloride, e taʻua o le PVC, o se tasi o ituaiga palasitika gaosi oloa, o le gaosiga o loʻo i ai nei e lona lua i le polyethylene.Polyvinyl chloride ua faʻaaogaina lautele i alamanuia, faʻatoʻaga ma le olaga i aso uma.O le Polyvinyl chloride o se polymer compound polymerized e vinyl chloride.E vevela.Pa'epa'e po'o le pa'epa'e samasama malamalama. E solu i ketones, esters, tetrahydrofurans ma chlorinated hydrocarbons.Fa'agata fa'ama'i sili.Le lelei le mautu vevela ma le malamalama tetee, sili atu i le 100 ℃ poʻo le umi o le faʻaalia i le susulu o le la na amata ona faʻaleagaina le hydrogen chloride, e manaʻomia e le gaosiga o palasitika le faʻamautu.E lelei le insulation eletise, e le mu.
Vasega S-700e masani lava ona faʻaaogaina e gaosia ai laupepa manino, ma e mafai ona taʻavale i pepa malo ma semi-malosi mo afifi, mea fola, ata malo mo le faʻalava (mo lole afifi pepa poʻo sikaleti ata tifaga), ma isi. E mafai foi ona extruded i malo pe ata tifaga semi-malosi, laupepa, po'o se pa e le masani ona fai mo afifi.Pe mafai foi ona tui e fai sooga, valve, vaega eletise, mea faʻaoga taavale ma vaʻa.
