High-gloss (optical) mapurasitiki anowanzo tarisa kune epurasitiki zvinhu zvine yakanakisa optical properties, uye zvinhu zvakajairika zvinosanganisira polymethylmethacrylate (PMMA), polycarbonate (PC), uye polystyrene (PS). Zvinhu izvi zvinogona kuve nekujeka kwakanyanya, kuramba kukwenya, uye kufanana kwemaziso mushure mekurapwa kwakakosha.
High-gloss mapurasitiki anoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzemaziso, dzakadai semagirazi emaziso, makamera emakamera, marambi emotokari, zvidzitiro zvefoni, zvikwangwani zvekucherechedza, nezvimwewo. Nekuda kwekunyatsojeka kwayo uye maoptical properties, high-gloss mapurasitiki anogona kunyatsoendesa chiedza uye kupa zvakajeka zvinoonekwa maitiro, uyewo kudzivirira mukati midziyo kubva kunze kwezvakatipoteredza. Pakazere, mapurasitiki epamusoro-soro ane huwandu hwakawanda hwekushandisa mukugadzira michina yemaziso, mateko ezvigadzirwa zvemagetsi, zvekuvakisa, nezvimwe minda, uye basa rawo nderekupa kuita kwakanaka kwemaziso nekudzivirira, asiwo kushongedza kutaridzika kwe. chigadzirwa.
Mamwe ematambudziko uye matambudziko anogona kusangana panguva yekugadziriswa kwepamusoro-gloss (optical) mapurasitiki anosanganisira zvinotevera:
Thermal deformation:Mamwe mapurasitiki akakwirira-anopenya anowanzoita deformation yekupisa panguva yekudziya, zvichikonzera kukanganisa kwehukuru hwechigadzirwa chakapedzwa kana chimiro. Naizvozvo, zvinodikanwa kudzora tembiricha uye kupisa nguva panguva yekugadziriswa uye kutora nzira dzakafanira dzekutonhora kudzikisa mhedzisiro yekupisa kwekupisa.
Burrs uye bubbles:Yakakwirira gloss epurasitiki zvinhu zvakanyanya brittle uye zvinowanzoita maburrs uye mabhuru. Izvi zvinogona kukanganisa kujeka uye optical properties. Kugadzirisa dambudziko iri, majekiseni akakodzera ekuumba maparamendi, sekudzikisa kumhanya kwejekiseni uye kuwedzera tembiricha yekuumbwa, inogona kushandiswa kudzikisa chizvarwa cheburrs uye mabhubhu emhepo.
Surface scratches:Yepamusoro-inopenya epurasitiki nzvimbo inotapukirwa nekukwenya, izvo zvinokanganisa maitiro avo ekuona uye kutaridzika kwemhando. Kuti udzivise kukwenya kwepamusoro, zvinodikanwa kushandisa zvakakodzera mold zvinhu uye mold pamusoro pekurapa uye teerera kudzivirira uye kubata pamusoro pechigadzirwa chakapedzwa panguva yekugadzirisa.
Uneven Optical Properties:Mune zvimwe zviitiko, kugadziriswa kwepamusoro-gloss mapurasitiki kunogona kutungamirira kune zvisina kuenzana optical properties, zvakadai sechitarisiko chemhute uye ruvara rwemavara. Kuti ugadzirise dambudziko iri, zvinodikanwa kunyatso kudzora kunaka kwezvinhu zvakasvibirira, kugadzirisa maitiro paramita, uye kunotevera kurapwa kwepamusoro kuti ive nechokwadi chekufanana kwezvinhu zvemaziso.
Aya ndiwo mamwe ematambudziko akajairika anogona kusangana panguva yekugadziriswa kwepamusoro-gloss (optical) mapurasitiki. Panogona kunge paine mamwe matambudziko chaiwo anoda kutariswa nekugadziriswa kune akasiyana zvinhu uye anoshanda mamiriro. Mukutarisana nedambudziko rekugadzirisa kwepamusoro-kupenya mapurasitiki, SILIKE yakagadzira yakagadziridzwa silicone additive inochengetedza kupera uye kuumbwa kwepamusoro-inopenya epurasitiki zvigadzirwa uku ichivandudza mashandiro ekugadzirisa.
Inochengeta yakakwira glossy magadzirirwo pasina kukanganisa kupera kwechigadzirwa--SILIKE ndiyo yekutanga sarudzo yekugadzira zvigadzirwa.
SILIKE SILIMER akatevedzanachigadzirwa chine refu-cheni alkyl-modified polysiloxane ine anoshanda anoshanda mapoka, kana masterbatch zvigadzirwa zvinoenderana neakasiyana thermoplastic resins. Nezvose zviri zviviri zvivakwa zvesilicone uye anoshanda anoshanda mapoka,SILIKE SILIMER zvigadzirwakuita basa guru mukugadzirisa mapurasitiki uye elastomers.
Nekuita kwakatanhamara senge yakakwira lubrication kunyatsoita, yakanaka solo kuburitswa, diki yekuwedzera huwandu, kuenderana kwakanaka nemapurasitiki, pasina kunaya kwemvura, uye zvakare inogona kuderedza zvakanyanya friction coefficient, kuvandudza kupfeka kuramba uye kukwenya kuramba kwechigadzirwa,SILIKE SILIMER zvigadzirwaanoshandiswa zvakanyanya kune PE, PP, PVC, PBT, PET, ABS, PC uye dzakatetepa-madziro zvikamu, nezvimwe.
Zvisinei,SILIKE SILIMER 5140, imhando yesilicone wax yakagadziridzwa nepolyester. iyi silicone yekuwedzera inogona kuenderana neyakawanda resin uye zvigadzirwa zvepurasitiki. uye inochengetedza kumira kwakanaka kwekupfeka kwesilicone, ine kugadzikana kwakanaka kwekupisa, uye kuita-inosimudzira mabhenefiti kuchengetedza kujeka kwezvinhu uye pachena, imhando yepamusoro yekuzora yemukati, inoburitsa mumiriri, uye inodzivirira-inodzivirira uye abrasion kuramba mumiriri wepurasitiki kugadzirisa.
Kana mamwe mapurasitiki akakodzera, anonatsiridza kugadziridzwa nekuita zvirinani mold kuzadza kuburitsa, kunaka kwemukati mafuta, uye yakagadziridzwa rheology ye resin kunyungudika. Hunhu hwepamusoro hunovandudzwa nekuwedzera kukwenya uye kupfeka kuramba, yakaderera COF, yakakwira pamusoro pegloss, uye nani girazi faibha wetting kana yakaderera fiber mabhureki, Inoshandiswa zvakanyanya mumhando dzese dze thermoplastic zvigadzirwa.
Zvikuru,SILIKE SILIMER 5140inopa mhinduro inoshanda yeHigh-gloss (optical) mapurasitiki PMMA, PS, uye PC, pasina chero mhedzisiro yakaipa paHigh-gloss (optical) mapurasitiki 'ruvara kana kujeka.
ForSILIKE SILIMER 5140, mazinga ekuwedzera ari pakati pe0.3 ~ 1.0% anokurudzirwa. Inogona kushandiswa mune yekirasi melt yekusanganisa maitiro senge Imwe / Twin screw extruders, jekiseni kuumba, uye padivi chikafu. Musanganiswa wemuviri nevirgin polymer pellets unokurudzirwa. Ehe, kune mafomula akasiyana emamiriro akasiyana, saka isu tinokurudzira kuti ubate SILIKE zvakananga, uye isu tichakupa iwe yakanakisa mhinduro ye thermoplastic processing uye pamusoro pemhando!
