PVC mana paipa mea mata
PVC mana paipa mea mata,
PVC mo paipa eletise, pvc resin mo paipa,
O le paipa eletise PVC ma lona auala sauniuni e aofia ai mea nei:
100 polyvinyl chloride resini,
15~25 calcium carbonate,
5~10 titanium oxide,
4~8 suiga fa'aaafiaga,
2~5 fa'amautu,
0.5~2 lubricant,
2~4 sepiolite
3~8 fa'apipi'i so'o fa'amaufa'ailoga afi, fa'asa'o fa'asa'o mumu mai se eleele e seāseā i ai le vai hydroxide aluminium hydroxide Sauniuniga metotia o le magnesium hydroxide ma le zinc borate.
Fa'agasologa o gaosiga:
1) Faʻaopopo le calcium carbonate titanium oxide i le POLYvinyl chloride resin ma faʻafefiloi i le saoasaoa maualuga mo le 3-6min;2) Ona fa'aopoopo lea i totonu ole fa'afefiloiga ole mea fa'amautu suiga suiga, lubricant sepiolite ma tu'u'ese'ese mumu mumu.
O le vevela faʻafefiloi o le 100-110, ma le taimi faʻafefiloi e 10-15 minute.A maeʻa ona faʻafefiloi lelei le paluga, ona tuʻuina atu lea o le paluga i le mea faʻafefiloi malulu i se saoasaoa maualalo o le 40 ~ 50 mo le 3-5 minute, ma mulimuli ane i totonu o le conical twin screw extruder i le 170 ~ 190 O le eletise eletise o loʻo i ai le afi mumu lelei ma mea tau masini
O le Polyvinyl Chloride (PVC) o se resini thermoplastic laina e gaosia e le polymerization o le monomer vinyl chloride.Ona o le eseesega o mea mata, e lua auala o le synthesizing vinyl chloride monomer calcium carbide process ma le suauu.Sinopec PVC faʻaaogaina faiga faʻamalolo se lua, mai le Kamupani Iapani Shin-Etsu Chemical ma American Oxy Vinyls Company.O le oloa o lo'o i ai le lelei o le fa'a'a'ala'au fa'ama'i, mea fa'amama eletise lelei ma le mautu lelei o vaila'au.Faatasi ai ma le maualuga o le chlorine, o le meafaitino e lelei le afi ma mea e tineia ai le tagata lava ia.O le PVC e faigofie ona faʻaogaina e ala i le faʻafefe, tui tui, calendering, faʻafefeteina, faʻamalosi, faʻafefeteina ma le vevela, ma isi.
Fa'atatauga
PVC o se tasi o resins thermoplastic sili ona faʻaaogaina.E mafai ona faʻaaogaina e fai ai oloa e maualuga le maaa ma le malosi, e pei o paipa ma mea faʻapipiʻi, faitotoa faʻailoga, faamalama ma laupepa afifi.
E mafai foʻi ona fai mea vaivai, e pei o ata tifaga, laupepa, uaea eletise ma uaea, laupapa fola ma paʻu synthetic, e ala i le faʻaopoopoga o mea faʻapipiʻi.
