1 Kev Taw Qhia
Feem ntau, ASA resin, terpolymer muaj xws li acrylate-styrene-acrylonitrile, yog npaj los ntawm grafting styrene thiab acrylonitrile polymers rau hauv acrylic roj hmab thiab feem ntau yog siv nyob rau hauv sab nraum zoov hluav taws xob qhov chaw, cov khoom siv, thiab cov khoom ntaus pob ncaws pob vim nws cov khoom zoo, nrog rau cov huab cua tsis kam. , chemical tsis kam, thiab ua haujlwm tau zoo.Txawm li cas los xij, kev siv ASA resins nyob rau hauv cov ntaub ntawv uas xav tau xim xws li liab, daj, ntsuab, thiab lwm yam yog txwv vim hais tias cov styrene thiab acrylonitrile tebchaw tsis graft txaus rau hauv acrylate roj hmab thaum lub sij hawm nws npaj thiab nthuav tawm cov acrylate roj hmab tam sim no nyob rau hauv, uas ua rau cov styrene thiab acrylonitrile compounds tsis graft txaus rau hauv acrylate roj hmab thaum lub sij hawm nws npaj thiab nthuav tawm cov acrylate roj hmab tam sim no nyob rau hauv. tsis zoo xim txuam thiab residual gloss.Tshwj xeeb, qhov ntsuas ntsuas ntawm cov monomers siv los npaj ASA resin yog 1.460 rau butyl acrylate, 1.518 rau acrylonitrile, thiab 1.590 rau styrene, xws li muaj qhov sib txawv loj ntawm qhov ntsuas qhov ntsuas ntawm cov roj hmab acrylate siv los ua cov tub ntxhais thiab cov refractive index ntawm cov tebchaw grafted rau hauv nws.Yog li, ASA resin muaj cov xim tsis zoo sib xws.Txij li thaum ASA resin yog opaque thiab tsis zoo txhua yam khoom xws li kev cuam tshuam cov khoom thiab tensile lub zog ntawm cov ntshiab resin, qhov no coj peb mus rau tam sim no R & D kev taw qhia thiab R & D txoj kev.
Cov thermoplastic feem ntau muaj tam sim no yog acrylonitrile-butadiene-styrene (ABS) polymers koom nrog roj hmab li butadiene polymers.ABS polymers muaj kev cuam tshuam zoo heev txawm tias qhov kub thiab txias, tab sis muaj huab cua tsis zoo thiab kev laus tsis kam.Yog li ntawd, nws yog tsim nyog los tshem tawm unsaturated ethylene polymers los ntawm graft copolymers nyob rau hauv thiaj li yuav npaj resins nrog zoo heev cuam tshuam lub zog nrog rau zoo heev huab cua thiab aging kuj.
ASA hmoov JCS-885 tsim los ntawm peb lub tuam txhab muaj ntau tshaj AS resin, thiab nws muaj qhov zoo ntawm kev ua haujlwm siab, kev ua haujlwm zoo heev, huab cua tsis zoo, thiab cov khoom muaj zog ntxiv.Nws yog siv rau hauv AS resin txhaj tshuaj molding.
2 Pom zoo noj
AS resin / ASA hmoov JCS-885 = 7/3, uas yog, rau txhua 100 qhov chaw ntawm AS cob alloy, nws yog tsim los ntawm 70 feem ntawm AS resin, thiab 30 feem ntawm ASA hmoov JCS-885.
3 Kev sib piv nrog cov khoom siv hauv tsev thiab txawv teb chaws ASA hmoov
1. Cov AS resin alloy tau npaj raws li cov qauv hauv Table 1 hauv qab no.

2. Ua cov kauj ruam ntawm AS resin alloy: Muab cov qauv saum toj no, ntxiv cov khoom sib xyaw rau hauv granulator rau thawj zaug fusion ntawm granules, thiab tom qab ntawd muab cov granules rau hauv lub tshuab txhaj tshuaj molding.
3. Kev ntsuam xyuas los sib piv cov khoom siv ntawm cov qauv strips tom qab txhaj tshuaj molding.
4. Kev sib piv kev ua tau zoo ntawm ASA hmoov JCS-885 thiab cov qauv txawv teb chaws yog qhia hauv Table 2 hauv qab no.
