Jekeseni Wopanga Kukhazikika Kwa Pulasitiki Yowonekera - PMMA, PC, PET
Nthawi yowerengera:3 mphindi, 37 masekondi
Mapulasitiki owoneka bwino omwe amagwiritsidwa ntchito kwambiri pamsika masiku ano ndi polymethyl methacrylate (yomwe imadziwika kuti acrylic kapena plexiglass, PMMA), polycarbonate (PC), polyethylene terephthalate (PET), nayiloni yowonekera, AS (acrylic-styrene copolymer), polysulfone (PSF) ndi zina zotero.Mapulasitiki atatu omwe amagwiritsidwa ntchito kwambiri ndi PMMA, PC ndi PET.Chifukwa cha kuchepa kwa malo, zotsatirazi ndizokambirana za katundu ndi jekeseni wopangira mapulasitiki atatuwa.Mukhozansokulumikizana ndi mainjiniya athumwachindunji kwa mautumiki ofunsira aulere.
1, PMMA
PMMA Pulasitiki Raw Material
PMMA imakhala ndi kukhuthala kwapamwamba komanso kuyenda kosauka pang'ono, kotero iyenera kubayidwa pa kutentha kwakukulu komanso kuthamanga kwambiri kwa jekeseni, kumene kutentha kwa jekeseni kumakhala ndi mphamvu yaikulu kuposa kuthamanga kwa jekeseni, ndipo kuwonjezereka kwa jekeseni, kumakhala bwinoko. kuchepa kwa mankhwala.
Jekeseni kutentha osiyanasiyana ndi lonse, kutentha kusungunuka ndi 160 ℃, pamene kutentha kutentha kufika 270 ℃, kotero zinthu kutentha kusintha osiyanasiyana ndi lonse ndi processability bwino.Choncho, kuti muwonjezere madzi, kutentha kwa jekeseni ndikofunikira.Zotsatira zoyipa, kulimba, zosavuta kukanda, zosavuta kung'amba ndi zovuta zina, ziyenera kuonjezedwa powonjezera kutentha kwa nkhungu, kukonza njira yochepetsera, kuthana ndi zolakwika izi.
2, pc
Tsamba la PC
PC ali mkulu mamasukidwe akayendedwe, mkulu kutentha kutentha, zamadzimadzi osauka, choncho ayenera kukhala apamwamba kutentha jekeseni (pakati 270-320 ℃), ndi yopapatiza osiyanasiyana kusintha kutentha zinthu, ndondomeko si zabwino monga PMMA, processing ndi zovuta pang'ono kuposa Mtengo PMMA.Kuthamanga kwa jekeseni pa mphamvu ya mphamvuyi ndi yaying'ono, koma chifukwa cha kukhuthala kwa ma viscosity, kumayenera kukhala kokulirapo kwa jekeseni, komwe kumayenera kupewedwa kuti muteteze kupsinjika kwamkati kuti muteteze kupsinjika kwamkati, nthawi yoti mupitirize kupanikizika iyenera kukhala. mwachidule momwe ndingathere.
3, PET
PET botolo
Kutentha kopanga PET ndikokwera, ndipo kusintha kwa kutentha kwa zinthu kumakhala kocheperako (260-300 ℃), kotero kuti kupanga kwake kumakhala koyipa, koma kusungunuka, madzimadzi amakhala abwino.Mphamvu zamakina ndi magwiridwe antchito sizokwera pambuyo pa jekeseni, ndipo ziyenera kusinthidwa kudzera mu njira yotambasula ndikusintha kuti ntchitoyo ikhale yabwino.
Kutentha kwa nkhungu kumafunika kuyendetsedwa bwino kuti zisawonongeke.Chofunika kwambiri pakusintha, chifukwa chake upangiri wa nkhungu zothamanga zotentha.Kutentha kwa nkhungu kuyenera kukhala kokwera apo kungayambitse kusawoneka bwino komanso zovuta pakuchotsa.
Zowonongeka ndi njira zothetsera mapulasitiki owonekera
Zowonongeka ndi pafupifupi izi:
Silver njere ndi kudzaza nkhungu ndi condensation ndondomeko, mkati kupsyinjika anisotropic chikoka, ofukula njira ya kupsyinjika, kotero kuti utomoni amayenda pa orientation, ndi sanali otaya kulunjika kutulutsa refractive index ndi kubadwa kwa kuwala filament. , ikakula, ikhoza kupangitsa kuti mankhwalawa awoneke ngati ming'alu.Kuwonjezera jekeseni akamaumba ndondomeko ndi nkhungu chidwi, mankhwala abwino annealing mankhwala.Mwachitsanzo, zinthu za PC zitha kutenthedwa mpaka 160 ℃ kapena kupitilira apo kwa mphindi 3-5, kenako kuzikhazikika mwachilengedwe.
Mpweya thovuchifukwa cha utomoni m'madzi ndi mpweya wina sangathe kutulutsidwa, (mu ndondomeko nkhungu condensation) kapena chifukwa chosakwanira kudzazidwa, condensing pamwamba ndi mofulumira condensation ndi mapangidwe zingalowe thovu.
Kuwala kosawoneka bwinochifukwa cha kuuma kwa nkhungu, kumbali ina kumakanda mofulumira kwambiri kotero kuti utomoni sungathe kutengera mawonekedwe a nkhungu pamwamba pake, zonsezi zimapangitsa kuti pamwamba pake apange kusagwirizana pang'ono, ndipo mankhwala amataya gloss.
Shock rippleamatanthauza mapangidwe wandiweyani ripple kuchokera pachipata chowongoka ngati pakati, chifukwa chake ndi chakuti mamasukidwe akayendedwe a kusungunula ndi aakulu kwambiri, zinthu kutsogolo wakhala condensed mu mbowo, ndiyeno zinthu zinathyola pamwamba condensation pamwamba, ndi pamwamba pa mantha ripple.
Chifunga choyeramakamaka chifukwa cha fumbi kugwa mu zopangira mu mlengalenga kapena yaiwisi chinyezi wochuluka ndi chifukwa.
Utsi woyera ndi mawanga akudamakamaka chifukwa cha kuwonongeka kapena kuwonongeka kwa mbiya utomoni chifukwa cha kutenthedwa m'deralo wa pulasitiki mu mbiya.
Kumangira jekeseni kumagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana ndipo kumatha kukwaniritsa kupanga kosasunthika, kolondola kwambiri kwa magawo munthawi yochepa.PorLean Tech imapereka ntchito zopangira jakisoni pazinthu zambiri, kuphatikiza mapulasitiki ndi ma elastomer.Mwachidulekwezani chitsanzo chanundipo pezani mawu ofulumira aulere ndi malangizo okhudzana ndi mautumiki.
