Chikombole chapulasitiki ndi chida chopangira zinthu zapulasitiki;ndi chida choperekera dongosolo lathunthu ndi miyeso yolondola kuzinthu zapulasitiki.Chomaliza chapulasitiki chimapezedwa ndi jekeseni akamaumba pulasitiki zopangira ndi pulasitiki nkhungu mu jekeseni akamaumba makina.Ndi zinthu ziti zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale a pulasitiki?
Pulasitiki yomwe timakamba nthawi zambiri imakhala mawu wamba.Nthawi zambiri, zida za pulasitiki zimagawidwa kukhala mapulasitiki wamba ndi mapulasitiki auinjiniya malinga ndi zolinga zawo.Zida za pulasitiki zomwe zimagwiritsidwa ntchito m'mafakitale a pulasitiki nthawi zambiri zimaphatikizapo ABS, PP, PVC, PC.Zida izi zimakondedwa ndi opanga ambiri chifukwa zimakhala ndi zofananira, makamaka muzinthu izi:
1. Zosavuta kukonza Ziwalo za nkhungu za jakisoni nthawi zambiri zimapangidwa ndi zitsulo, ndipo mawonekedwe ena ndi ovuta kwambiri.Pofuna kufupikitsa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake
2. Mphamvu yapamwamba yamakina, kukana kwamphamvu kwambiri, sikungagwere mwachangu pa kutentha kochepa;kumva bwino kwa notch, kukana bwino kwa kukwawa, sikungagwere mwachangu kutentha kukakwera;kukhala ndi kuuma kwina kwapamwamba, kukana kukankha;Kukaniza kwabwino kovala komanso kocheperako kocheperako.
3. Kukana kuvala kwabwino Kuwala ndi kulondola kwa pamwamba pa zigawo za pulasitiki zimagwirizana mwachindunji ndi kukana kuvala pamwamba pa nkhungu, makamaka pamene ulusi wagalasi, zodzaza ndi inorganic fillers ndi ma pigment ena amawonjezedwa ku mapulasitiki ena, sali. zogwirizana ndi mapulasitiki.Kusungunuka kumayenda pa liwiro lalikulu mu wothamanga ndi patsekeke palimodzi, ndi kukangana pamwamba pa patsekeke ndi lalikulu kwambiri.Ngati zinthuzo sizikutha kuvala, posachedwapa zidzatha, zomwe zingawononge ubwino wa zigawo zapulasitiki.
4. Kuchita bwino kwa magetsi, osakhudzidwa ndi kutentha, chinyezi ndi kusintha kwafupipafupi.
5. High dzimbiri kukana Ma resins ambiri ndi zowonjezera zimakhala ndi mphamvu zowononga pamwamba pa patsekeke.Kuwonongeka kumeneku kumapangitsa kuti zitsulo zomwe zili pamwamba pabowo ziwonongeke, zimasefukira, zimawonongeka, komanso zimawononga pulasitiki.Choncho, ndi bwino kugwiritsa ntchito zitsulo zosagwira dzimbiri, kapena chrome-yokutidwa kapena chinganga-nickel pamtunda.
6. Kutsika kwa kutentha kwapansi mpaka -40 madigiri Celsius, asidi, alkali, mchere, mafuta, madzi.
7. Good dimensional bata Pakuumba jekeseni, kutentha kwa jekeseni wa nkhungu kuyenera kufika pamwamba pa 300 °C.Pachifukwa ichi, ndi bwino kusankha chitsulo chachitsulo (chitsulo chotenthetsera kutentha) chomwe chakhala chikuwotchedwa bwino.Apo ayi, zingayambitse kusintha kwa microstructure ya zinthu, zomwe zimabweretsa kusintha kwa kukula kwa nkhungu.
8. Zing'onozing'ono shrinkage mlingo ndi lonse akamaumba ndondomeko osiyanasiyana;processing pamwamba mankhwala akhoza kuchitidwa ndi ❖ kuyanika, kusindikiza, electroplating ndi njira zina.
9. Zochepa zomwe zimakhudzidwa ndi chithandizo cha kutentha Pofuna kukonza kuuma ndi kuvala kukana, nkhungu nthawi zambiri imakhala ndi kutentha, koma chithandizochi chiyenera kupangitsa kukula kwake kukhala kochepa kwambiri.Choncho, ndi bwino kugwiritsa ntchito zitsulo zolimba zomwe zingathe kupangidwa.
10. Kuchita bwino kwa kupukuta Zigawo za pulasitiki nthawi zambiri zimafuna gloss yabwino ndi mawonekedwe apamwamba, kotero kuti roughness ya pamwamba pake iyenera kukhala yaying'ono kwambiri.Mwa njira imeneyi, pamwamba pa patsekeke ayenera pansi processing pamwamba, monga kupukuta, akupera, etc. Choncho, chitsulo chosankhidwa sayenera kukhala ndi zosafunika akhakula ndi pores.
Ndi chitukuko mosalekeza luso zoweta pulasitiki m'zaka zaposachedwa, ndondomeko akamaumba pulasitiki wakhala mosalekeza bwino.Amakhulupirira kuti posachedwapa, jekeseni wa pulasitiki wopangira pulasitiki kuchokera ku nkhungu zapulasitiki zidzagwiritsidwa ntchito kwambiri m'madera onse a moyo.
