Chidule:Mtundu watsopano wa ufa wa rabara womwe umagwiritsidwa ntchito kukonza makina a AS utomoni monga kukana mphamvu, kuonjezera mphamvu ya mankhwala ndi kupititsa patsogolo ukalamba wa mankhwala-ASA rabara ufa JCS-887, wogwiritsidwa ntchito ku jekeseni wa jekeseni wa AS.Ndi mankhwala a pachimake-chipolopolo emulsion polymerization ndipo ali ngakhale wabwino ndi AS utomoni.Ikhoza kupititsa patsogolo makina a mankhwala popanda kuchepetsa kukalamba kwa mankhwala ndipo amagwiritsidwa ntchito popanga jekeseni.
Mawu osakira:AS utomoni, ASA mphira 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 pokonzekera 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 wosawoneka bwino wamakina monga momwe zimakhudzira mphamvu 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 kumakhala 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.
Ufa wa rabara wa ASA JCS-887 wopangidwa ndi kampani yathu umagwirizana kwambiri ndi utomoni wa AS, ndipo uli ndi maubwino okana kukhudzidwa kwambiri, magwiridwe antchito abwino kwambiri, kukana kwanyengo, komanso kuchuluka kwamphamvu kwazinthu.Amagwiritsidwa ntchito mu jekeseni wa AS resin.
2 Analimbikitsa Mlingo
AS utomoni/ASA mphira ufa JCS-887=7/3, ndiko kuti, pa magawo 100 aliwonse a AS utomoni aloyi, wapangidwa ndi 70 mbali za AS utomoni, ndi 30 mbali za ASA rabala ufa JCS-887.
3 Kuyerekeza kwa magwiridwe antchito ndi ufa wamba wa ASA wamba ndi wakunja
1. The AS resin alloy inakonzedwa molingana ndi ndondomeko mu Table 1 pansipa.
Table 1
| Kupanga | |
| Mtundu | Misa/g |
| AS Resin | 280 |
| AS Rubber ufa JCS-887 | 120 |
| Njira yothirira mafuta | 4 |
| Wothandizira | 2.4 |
| Antioxidant | 1.2 |
2. Kukonza masitepe a AS utomoni aloyi: Phatikizani chilinganizo pamwambapa, onjezani pawiri pa granulator kuti maphatikizidwe koyambirira kwa ma granules, ndiyeno ikani ma granules mu makina opangira jakisoni kuti apange jekeseni.
3. Yesani kufananiza mawonekedwe amakanika amizere yachitsanzo mutatha kuumba jekeseni.
4. Kuyerekeza kwa ntchito pakati pa ASA rabara ufa JCS-887 ndi zitsanzo zakunja zikuwonetsedwa mu Table 2 pansipa.
Table 2
| Kanthu | Njira yoyesera | Zoyeserera | Chigawo | Mlozera waukadaulo (JCS-887) | Mlozera waukadaulo (chitsanzo chofananira) |
| Vicat kufewetsa kutentha | Mtengo wa GB/T 1633 | B120 | ℃ | 90.2 | 90.0 |
| Kulimba kwamakokedwe | GB/T 1040 | 10 mm / mphindi | MPa | 34 | 37 |
| Kutalika kwamphamvu panthawi yopuma | GB/T 1040 | 10 mm / mphindi | % | 4.8 | 4.8 |
| Mphamvu yopindika | Mtengo wa GB/T9341 | 1mm/mphindi | MPa | 57 | 63 |
| Kupindika modulus ya elasticity | Mtengo wa GB/T9341 | 1mm/mphindi | GPA | 2169 | 2189 |
| Mphamvu yamphamvu | Mtengo wa GB/T 1843 | 1A | KJ/m2 | 10.5 | 8.1 |
| Kuuma kwa nyanja | Mtengo wa GB/T2411 | Shore D | 88 | 88 |
4 Mapeto
Pambuyo poyesa kutsimikizira, ufa wa rabara wa ASA JCS-887 wopangidwa ndi kampani yathu ndi AS jekeseni wa jekeseni wa resin, mbali zonse zamakina zamakina zakonzedwa bwino, ndipo m'mbali zonse sizitsika poyerekeza ndi ufa wina wa rabara kunyumba ndi kunja.
