1 Folasaga
E masani lava, o le resin ASA, o le terpolymer e aofia ai le acrylate-styrene-acrylonitrile, e saunia e ala i le faapipiiina o styrene ma acrylonitrile polymers i totonu o le paʻu acrylic ma e masani ona faʻaaogaina i fafo eletise eletise, mea faufale, ma mea tau taʻaloga ona o ona meatotino lelei, e aofia ai le tau. , tete'e i vaila'au, ma le fa'atinoina.Ae ui i lea, o le faʻaaogaina o resini ASA i mea e manaʻomia ai lanu e pei o le mumu, samasama, lanumeamata, ma isi mea e faʻatapulaʻa ona o le styrene ma le acrylonitrile e le mafai ona sulu lelei i totonu o le paʻu acrylate i le taimi o sauniuniga ma faʻaalia ai le paʻu acrylate o loʻo iai i totonu, e mafua ai. le fetaui lanu ma le iila totoe.Aemaise lava, o faʻailoga faʻasolosolo o monomers na faʻaaogaina e saunia ai le resini ASA o le 1.460 mo le butyl acrylate, 1.518 mo le acrylonitrile, ma le 1.590 mo le styrene, e pei ona i ai se eseesega tele i le va o le faasino igoa o le paʻu acrylate faʻaaogaina e fai ma autu ma le fa'ailoga fa'afoliga o mea fa'afefiloi ua sulu i totonu.O le mea lea, o le ASA resin e leaga le lanu e fetaui lelei.Talu ai ona o le ASA resin o le opaque ma le le lelei o mea faʻainisinia e pei o aʻafiaga o mea ma le malosi faʻamalosi o le resin mama, o lenei mea e aumaia ai i tatou i le taimi nei R & D faʻataʻitaʻiga ma R & D auala.
O fa'aputuga masani fa'avelavela o lo'o maua i le taimi nei o polymers acrylonitrile-butadiene-styrene (ABS) fa'atasi ma le pa'u e pei o polymers butadiene.O polymers ABS e sili atu le malosi o le a'afiaga e tusa lava pe maualalo le vevela, ae e leaga le tau ma le matua tetee.O le mea lea, e tatau ona aveese polymers ethylene unsaturated mai copolymers sulu ina ia saunia resins e sili atu le malosi o le aafiaga faatasi ai ma le lelei o le tau ma le matua tetee.
O le ASA paʻu JCS-885 na atiina ae e la matou kamupani e sili atu ona fetaui ma le AS resin, ma e iai le lelei o le maualuga o le teteʻe, faʻaleleia lelei le gaioiga, lelei le tetee o le tau, ma le faʻateleina o le malosi o oloa.E faʻaaogaina i le AS resin injection molding.
2 Fusi Fautuaina
AS resin/ASA pa'u JCS-885=7/3, o lona uiga, mo vaega uma e 100 ole AS resin alloy, e aofia ai le 70 vaega ole AS resin, ma le 30 vaega ole ASA pa'u JCS-885.
3 Fa'atusatusaga fa'atinoga ma le pauta ASA i totonu ma fafo
1. O le AS resin alloy na saunia e tusa ai ma le fua fa'atatau i le Laulau 1 i lalo.
Laulau 1
| Fuafuaga | |
| Ituaiga | Massa/g |
| AS Resin | 280 |
| ASA Pa'u JCS-885 | 120 |
| Fua fa'asu'u | 4 |
| Sui Fesootaiga | 2.4 |
| Antioxidant | 1.2 |
2. Laasaga o le faʻagasologa o le AS resin alloy: Faʻapipiʻi le fua o loʻo i luga, faʻaopoopo le faʻapipiʻi i le granulator mo le fusi muamua o granules, ona tuʻu lea o granules i totonu o le masini faʻapipiʻi tui mo tui.
3. Fa'ata'ita'i e fa'atusatusa uiga fa'ainisinia o fasi pepa fa'ata'ita'i pe a uma ona tu'iina.
4. O le faʻatusatusaga o faʻatinoga i le va o le ASA paʻu JCS-885 ma faʻataʻitaʻiga mai fafo o loʻo faʻaalia i le Laulau 2 i lalo.

4 Faaiuga
I le maeʻa ai o le faʻataʻitaʻiga faʻataʻitaʻiga, o le ASA paʻu JCS-885 na atiae e la matou kamupani ma le AS resin injection molding, o vaega uma o mea faʻainisinia ua faʻaleleia, ma i itu uma e le maualalo i isi paʻu i le fale ma fafo.
