Chifukwa transmittance mkulu wa pulasitiki mandala, pali zofunika okhwima padziko khalidwe la mankhwala pulasitiki, monga palibe mawanga, palibe mapatani, porosity, yoyera, m'mphepete mizere, mawanga wakuda, ma discoloration, mkangano luster, etc. Choncho, mu chonsejekeseni akamaumbandondomeko, payenera kukhala okhwima ndi wapadera zofunika kwa zipangizo, zipangizo, zisamere pachakudya ngakhale kupanga mankhwala.
Popeza mapulasitiki owonekera nthawi zambiri amakhala ndi malo osungunuka kwambiri koma osayenda bwino, kusintha kutentha kwa makina, kuthamanga kwa jekeseni, ndi liwiro la jekeseni kuti zitsimikizire kuti pamwamba pa jekeseni zimatha kudzaza malo a jekeseni ndikuchepetsa kuthekera kopanga kupsinjika kwamkati ndikupangitsa kupindika ndi kusweka.Choncho, ntchito okhwima ayenera kuchitidwa pokonzekera zopangira, zipangizo monga bwino pulasitiki akamaumba zida ndi jekeseni nkhungu zofunika, jekeseni akamaumba ndondomeko ndi zopangira akuchitira mankhwala.Kodi mungapangire bwanji pulasitiki yowonekera bwino?Izi ndi zina zomwe muyenera kudziwa:
1. Kukonzekera ndi kuyanika zipangizo
Popeza zonyansa pang'ono mu pulasitiki zidzakhudza kuwonekera kwa mankhwalawo, mankhwalawa ayenera kusindikizidwa bwino panthawi yosungira, zoyendetsa ndi kudyetsa kuti zitsimikizidwe kuti mankhwalawa ndi oyera, makamaka zopangira zimakhala zosavuta kuwonongeka pambuyo potentha.Pali chinyezi chochepa, choncho chiyenera kuumitsidwa padzuwa.Kuphatikiza apo, hopperyo iyenera kuwumitsidwa podyetsa.Komanso, mpweya wolowa uyenera kusefedwa ndi kuchepetsedwa panthawi yowumitsa kuti uwonetsetse kuti sudzaipitsa zopangira.
2.Kuyeretsa mbiya, screw ndi zina zowonjezera
Kuti mupewe kuipitsidwa kwa zinthu zopangira ndi zotsalira zobisika kapena zonyansa m'malo opangira zida, makamaka utomoni wokhala ndi kukhazikika kwamafuta, pulasitiki pa nkhungu ndi wononga makina ayenera kutsukidwa ndi oyeretsa kuti achotseretu zonyansa, kapena mu kusowa kwa zotsuka zotsuka, gwiritsani ntchito PE, PS ndi ma resins ena kuyeretsa wononga.Mukatsekedwa mwadzidzidzi, pofuna kupewa kuwonongeka kwa zinthu zopangira kutentha kwa nthawi yayitali, kutentha kwa chowumitsira ndi mbiya kuyenera kuchepetsedwa, monga PC, PMMA mbiya kutentha kuyenera kukhala pansi pa madigiri 160 (kutentha kwa hopper kuyenera kuchepetsedwa. kuchepetsedwa mpaka pansi pa madigiri 100 PC).
3.Injection nkhungu kapangidwe ayenera kulabadira mfundo zotsatirazi (kuphatikiza mankhwala kapangidwe)
Mfundo zotsatirazi ziyenera kuzindikirika popanga jekeseni wa jekeseni kuti ateteze pulasitiki yosauka, kuwonongeka kwa pamwamba ndi kuwonongeka komwe kumachitika chifukwa cha kusayenda bwino kapena kuzizira kosiyana.
a) Makulidwe a khoma akuyenera kukhala osasinthasintha momwe angathere komanso otsetsereka a nkhungu akhale akulu momwe angathere.
b) Kusinthaku kuyenera kukhala kofewa komanso kosalala kuti tipewe ngodya zakuthwa ndi m'mphepete, makamaka pazinthu zamakompyuta, ndipo pasakhale mipata.
c) Mpata: Wothamanga ayenera kukhala wamkulu ndi waufupi momwe angathere, ndipo malo a chipata ayenera kukhala molingana ndi ndondomeko ya kuchepa.Zinthu zozizira zimafunika bwino ngati kuli kofunikira.
d) Jekeseni nkhungu pamwamba ayenera kukhala yosalala ndi otsika roughness (max Ra0.8)
e) Kuchuluka kwa mabowo olowera mpweya ndi malo otsekera kuyenera kukhala kokwanira kutulutsa mpweya ndi mpweya kuchokera pakusungunuka.
f) Makulidwe a khoma sayenera kukhala owonda kwambiri kupatula zinthu za PET, nthawi zambiri zosachepera 1mm.
