Mapulasitiki onyezimira kwambiri (opangidwa ndi kuwala) nthawi zambiri amatanthauza zinthu zapulasitiki zokhala ndi mawonekedwe owoneka bwino, ndipo zida zodziwika bwino ndi polymethylmethacrylate (PMMA), polycarbonate (PC), ndi polystyrene (PS).Zidazi zimatha kukhala zowonekera bwino, kukana zokanda, komanso mawonekedwe owoneka bwino pambuyo pa chithandizo chapadera.
Mapulasitiki onyezimira kwambiri amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana a kuwala, monga magalasi a maso, makamera a makamera, nyali zamagalimoto, zowonetsera mafoni a m'manja, mapepala owunikira, ndi zina zotero.Chifukwa cha mawonekedwe ake owoneka bwino komanso owoneka bwino, mapulasitiki owoneka bwino amatha kutumiza bwino kuwala ndikupereka mawonekedwe owoneka bwino, komanso kuteteza zida zamkati ku chilengedwe chakunja.Ponseponse, mapulasitiki onyezimira kwambiri amakhala ndi ntchito zosiyanasiyana popanga zida zowoneka bwino, zipolopolo zamagetsi zamagetsi, zida zomangira, ndi magawo ena, ndipo udindo wawo makamaka ndikupereka magwiridwe antchito abwino komanso chitetezo, komanso kukongoletsa mawonekedwe. mankhwala.
Zina mwazovuta ndi zovuta zomwe zingakumane nazo pakukonza mapulasitiki owoneka bwino (owoneka bwino) ndi awa:
Thermal deformation:Mapulasitiki ena onyezimira kwambiri amatha kupindika pakuwotcha, zomwe zimapangitsa kusokoneza kukula kapena mawonekedwe ake.Choncho, m'pofunika kulamulira kutentha ndi nthawi yotentha panthawi yokonza ndikutenga njira zoyenera zoziziritsira kuti muchepetse zotsatira za kutentha kwa kutentha.
Burrs ndi thovu:Zida zapulasitiki zonyezimira kwambiri zimakhala zolimba kwambiri komanso zimatha kukhala ndi ma burrs ndi thovu.Izi zitha kukhudza kuwonekera komanso mawonekedwe a kuwala.Kuti athetse vutoli, magawo oyenera opangira jekeseni, monga kutsitsa liwiro la jekeseni ndikuwonjezera kutentha kwa nkhungu, angagwiritsidwe ntchito kuchepetsa kubadwa kwa burrs ndi thovu la mpweya.
Kukwapula pamwamba:Mapulasitiki onyezimira kwambiri amatha kukwapula, zomwe zimakhudza mawonekedwe awo komanso mawonekedwe ake.Pofuna kupewa zokopa pamwamba, m'pofunika kugwiritsa ntchito zipangizo zoyenera nkhungu ndi nkhungu pamwamba mankhwala ndi kulabadira kuteteza ndi kuchitira pamwamba mankhwala yomalizidwa pokonza.
Zosiyanasiyana Zowoneka:Nthawi zina, kukonza mapulasitiki onyezimira kwambiri kumatha kupangitsa kuti pakhale mawonekedwe owoneka bwino, monga mawonekedwe a chifunga komanso kutayika kwamtundu.Kuthetsa vutoli, m`pofunika mosamalitsa kulamulira khalidwe la zipangizo, magawo processing ndondomeko, ndi wotsatira pamwamba mankhwala kuonetsetsa kufanana kwa katundu kuwala.
Izi ndi zina mwazovuta zomwe zimakumana nazo panthawi yokonza mapulasitiki owoneka bwino (owoneka bwino).Pakhoza kukhala mavuto ena enieni omwe akuyenera kuganiziridwa ndi kuthetsedwa pazinthu zosiyanasiyana ndi zochitika zenizeni.Poyang'anizana ndi vuto la kukonza mapulasitiki onyezimira kwambiri, SILIKE yapanga chowonjezera cha silicone chomwe chimasunga kutha ndi kapangidwe kazinthu zapulasitiki zonyezimira komanso kuwongolera magwiridwe antchito.
Imakhala ndi mawonekedwe onyezimira kwambiri osakhudza kutha kwa chinthucho——SILIKE ndiye chisankho choyamba chothandizira kukonza.
Mndandanda wa SILIKE SILIMERndi mankhwala okhala ndi unyolo wautali wa alkyl-modified polysiloxane wokhala ndi magulu ogwira ntchito, kapena zinthu za masterbatch zochokera ku utomoni wosiyanasiyana wa thermoplastic.Ndi zonse za silicone ndi magulu ogwira ntchito,SILIKE SILIMER mankhwalaamatenga gawo lalikulu pakukonza mapulasitiki ndi elastomers.
Ndi machitidwe odziwika bwino monga mafuta odzola kwambiri, kutulutsidwa kwabwino kwaumwini, kuchuluka kwazing'ono, kugwirizanitsa bwino ndi mapulasitiki, kulibe mpweya, komanso kumachepetsanso kwambiri mikangano, kupititsa patsogolo kukana komanso kukana kwa zinthu,SILIKE SILIMER mankhwalachimagwiritsidwa ntchito Pe, PP, PVC, PBT, PET, ABS, PC ndi mbali woonda-mipanda, etc.
Komabe,SILIKE SILIMER 5140, ndi mtundu wa sera ya silikoni yosinthidwa ndi poliyesitala.chowonjezera ichi cha silicone chikhoza kugwirizana bwino ndi utomoni wambiri ndi zinthu zamapulasitiki.ndipo imasunga kukana bwino kwa silikoni, yokhala ndi kukhazikika kwamafuta abwino, komanso mapindu owonjezera kuti asunge kumveka bwino kwa zinthu komanso kuwonekera, ndimafuta abwino kwambiri amkati, otulutsa, komanso osagwirizana ndi zokanda komanso abrasion pokonza pulasitiki.
Mapulasitiki owonjezera akayenera, amathandizira kukonza ndi kutulutsa bwino kwa nkhungu, mafuta abwino amkati, komanso kusintha kwabwino kwa resin kusungunuka.Ubwino wapamtunda umatheka chifukwa cha kuchulukira komanso kukana kuvala, kutsika kwa COF, gloss yapamwamba kwambiri, komanso kunyowetsa magalasi abwinoko kapena mabuleki otsika, Amagwiritsidwa ntchito kwambiri pazinthu zamitundu yonse ya thermoplastic.
Makamaka,SILIKE SILIMER 5140imapereka njira yabwino yothetsera mapulasitiki a High-gloss (optical) PMMA, PS, ndi PC, popanda vuto lililonse pamtundu wa pulasitiki wowala kwambiri (wowala) kapena kumveka bwino.
ZaSILIKE SILIMER 5140, milingo yowonjezera pakati pa 0.3 ~ 1.0% imaperekedwa.Itha kugwiritsidwa ntchito mumayendedwe akale osakaniza osungunula monga Single / Twin screw extruders, jekeseni akamaumba, ndi chakudya chakumbali.Kuphatikizika kwakuthupi ndi ma pellets a namwali a polima kumalimbikitsidwa.Zachidziwikire, pali mitundu yosiyanasiyana yamachitidwe osiyanasiyana, chifukwa chake tikupangira kuti mulumikizane ndi SILIKE mwachindunji, ndipo tidzakupatsirani njira yabwino kwambiri yopangira thermoplastic ndi mawonekedwe apamwamba!
