Abstract:Rudzi rutsva rwehupfu hunoshandiswa kuvandudza michina yeAS resin yakadai sekupikisa kupikisa, kuwedzera simba rechigadzirwa uye kugadzirisa kukwegura kwechigadzirwa-ASA powder JCS-885, inoshandiswa kune AS resin injection molding.Icho chigadzirwa che core-shell emulsion polymerization uye ine kuenderana kwakanaka neAS resin.Inogona kuvandudza michina yechigadzirwa pasina kuderedza kuchembera kwechigadzirwa uye inoshandiswa mukuumba jekiseni.
Keywords:AS resin, ASA hupfu, mechanical zvivakwa, weathering kuramba, jekiseni kuumba.

1. Nhanganyaya
Kazhinji, ASA resin, terpolymer inosanganisira acrylate-styrene-acrylonitrile, inogadzirwa nekubatanidza styrene uye acrylonitrile polymers mu acrylic rabha uye inowanzoshandiswa mukunze kwemagetsi zvikamu, zvekuvakisa, uye zvinhu zvemitambo nekuda kwehunhu hwayo hwakanaka, kusanganisira kuramba kwemamiriro ekunze. , makemikari kuramba, uye kushanda.Nekudaro, kushandiswa kweASA resins mumidziyo inoda mavara akadai dzvuku, yero, girini, nezvimwewo kunogumira nekuti styrene uye acrylonitrile makomisheni haasanganisire zvakakwana muacrylate rabha panguva yekugadzirira uye kuburitsa acrylate rubber iripo imomo, zvichikonzera kusakwana kwemavara uye kusara kupenya.Kunyanya, iyo refractive indices yemamonomers akashandiswa kugadzira iyo ASA resin yaive 1.460 yebutyl acrylate, 1.518 ye acrylonitrile, uye 1.590 ye styrene, zvekuti pakanga paine musiyano mukuru pakati peiyo refractive index ye acrylate rubber yakashandiswa sepakati uye refractive index yemakomponi akabatanidzwa mairi.Naizvozvo, ASA resin ine yakashata ruvara inoenderana zvivakwa.Sezvo ASA resin iri opaque uye isiri-yakanakisa michina zvivakwa senge zvinokanganisa zvivakwa uye tensile simba resina yakachena resin, izvi zvinotiunza kune yazvino R&D gwara uye R&D nzira.
Iwo akajairika thermoplastic nziyo dziripo parizvino acrylonitrile-butadiene-styrene (ABS) mapolymers akabatanidzwa nerabha sebutadiene polymers.ABS ma polymers ane yakanakisa simba rekuita kunyangwe kune yakaderera tembiricha, asi ine mamiriro ekunze asina kunaka uye kuramba kuchembera.Naizvozvo, zvinodikanwa kubvisa unsaturated ethylene polymers kubva kugraft copolymers kuitira kuti ugadzirire resin zvine simba rekuita rakanakisa pamwe nekunaka kwemamiriro ekunze uye kuramba kuchembera.
Iyo ASA poda JCS-885 yakagadziridzwa nekambani yedu inonyanya kuenderana neAS resin, uye ine zvakanakira zvekupikisa zvakanyanya, kuita kwakanakisa kwekugadzirisa, kunaka kwemamiriro ekunze, uye kuwedzera simba rechigadzirwa.Inoshandiswa muAS resin jekiseni molding.
2 Recommended Dosage
AS resin/ASA powder JCS-885=7/3, kureva kuti, pazvikamu zana zveAS resin alloy, inoumbwa nezvikamu makumi manomwe zveAS resin, uye zvikamu makumi matatu zveASA powder JCS-885.
3 Performance kuenzanisa neyemukati uye yekunze mainstream ASA poda
1. Iyo AS resin alloy yakagadzirwa maererano nemaitiro muTebhurari 1 pazasi.
