Chidule:Mtundu watsopano wa ufa womwe umagwiritsidwa ntchito pokonzanso makina a AS utomoni monga kukana mphamvu, kuwonjezera mphamvu ya mankhwala ndi kupititsa patsogolo ukalamba wa mankhwala-ASA powder JCS-885, yogwiritsidwa ntchito ku jekeseni wa AS resin.Ndi mankhwala a pachimake-chipolopolo emulsion polymerization ndipo ali ngakhale wabwino AS utomoni.Ikhoza kupititsa patsogolo makina a mankhwala popanda kuchepetsa kukalamba kwa mankhwala ndipo amagwiritsidwa ntchito popanga jekeseni.
Mawu osakira:AS utomoni, ASA ufa, makina katundu, kukana nyengo, jekeseni akamaumba.

1 Mawu Oyamba
Nthawi zambiri, utomoni wa ASA, terpolymer wopangidwa ndi acrylate-styrene-acrylonitrile, umakonzedwa ndikulumikiza ma polima a styrene ndi acrylonitrile mu mphira wa acrylic ndipo amagwiritsidwa ntchito kwambiri pazigawo zamagetsi zakunja, zida zomangira, ndi zinthu zamasewera chifukwa cha zabwino zake, kuphatikiza kukana nyengo. , kukana mankhwala, ndi ntchito.Komabe, kugwiritsa ntchito utomoni wa ASA muzinthu zomwe zimafuna mitundu yofiira, yachikasu, yobiriwira, ndi zina ndizochepa chifukwa ma styrene ndi acrylonitrile samalumikiza mokwanira mu rabara ya acrylate panthawi yokonzekera ndikuwulula mphira wa acrylate womwe ukupezekamo, zomwe zimapangitsa kusafananitsa mitundu ndi gloss yotsalira.Mwachindunji, ma refractive indices a monomers omwe amagwiritsidwa ntchito popanga utomoni wa ASA anali 1.460 wa butyl acrylate, 1.518 wa acrylonitrile, ndi 1.590 wa styrene, kotero kuti panali kusiyana kwakukulu pakati pa refractive index ya rabara ya acrylate yomwe imagwiritsidwa ntchito ngati pachimake ndi mphira. refractive index wa mankhwala kumezanitsidwa mmenemo.Chifukwa chake, utomoni wa ASA umakhala ndi zofananira zamitundu.Popeza utomoni wa ASA ndi wowoneka bwino komanso wosakhala bwino wamakina monga momwe zimakhudzira komanso kulimba kwa utomoni wangwiro, izi zimatifikitsa kumayendedwe apano a R&D ndi njira ya R&D.
Mitundu yodziwika bwino ya thermoplastic yomwe ilipo pano ndi ma polima acrylonitrile-butadiene-styrene (ABS) ophatikizidwa ndi mphira ngati ma polima a butadiene.Ma polima a ABS amakhala ndi mphamvu zabwino kwambiri ngakhale kutentha kotsika kwambiri, koma amakhala ndi nyengo yoyipa komanso kukana kukalamba.Chifukwa chake, ndikofunikira kuchotsa ma polima a unsaturated ethylene kuchokera ku ma copolymers a graft kuti akonzere utomoni wokhala ndi mphamvu zowoneka bwino komanso kupirira kwanyengo komanso kukana kukalamba.
ASA ufa JCS-885 wopangidwa ndi kampani yathu ndi wogwirizana kwambiri ndi AS utomoni, ndipo uli ndi ubwino wokana kwambiri, ntchito yabwino yokonzekera, kukana kwa nyengo, ndi kuwonjezereka kwamphamvu kwa mankhwala.Amagwiritsidwa ntchito mu jekeseni wa AS resin.
2 Analimbikitsa Mlingo
AS utomoni/ASA ufa JCS-885=7/3, ndiko kuti, pa magawo 100 aliwonse a AS resin alloy, amapangidwa ndi magawo 70 a AS utomoni, ndi magawo 30 a ASA ufa JCS-885.
3 Kuyerekeza kwa magwiridwe antchito ndi ufa wamba ndi wakunja wa ASA
1. The AS resin alloy inakonzedwa molingana ndi ndondomeko mu Table 1 pansipa.
Table 1
| Kupanga | |
| Mtundu | Misa/g |
| AS Resin | 280 |
| ASA Powder JCS-885 | 120 |
| Njira Yopangira Mafuta | 4 |
| Wothandizira Wogwirizana | 2.4 |
| Antioxidant | 1.2 |
2. Kukonza masitepe a AS utomoni aloyi: Phatikizani chilinganizo pamwamba, onjezani pawiri pa granulator kuti maphatikizidwe koyambirira kwa ma granules, ndiyeno ikani ma granules mu makina opangira jekeseni kuti apange jekeseni.
3. Yesetsani kufananitsa makina azitsulo zazitsulo pambuyo popanga jekeseni.
4. Kuyerekeza kwa ntchito pakati pa ASA powder JCS-885 ndi zitsanzo zakunja zikuwonetsedwa mu Table 2 pansipa.

4 Mapeto
Pambuyo poyesa kutsimikizira, ufa wa ASA JCS-885 wopangidwa ndi kampani yathu ndi AS jekeseni wa jekeseni wa resin, mbali zonse zamakina zimakonzedwa bwino, ndipo m'mbali zonse sizitsika ndi ufa wina kunyumba ndi kunja.
