Chilichonse chomwe muyenera kudziwa pazazinthu zakuthupi za PS kuti mukhale ndi tepi yabwino kwambiri yonyamula

Zinthu za polystyrene (PS) ndizosankha zodziwika bwino zonyamula tepi zopangira chifukwa cha mawonekedwe ake apadera komanso mawonekedwe ake.M'nkhaniyi, tiyang'ana mwatsatanetsatane zakuthupi za PS ndikukambirana momwe zimakhudzira kuumba.

PS zinthu ndi polima thermoplastic ntchito m'mafakitale osiyanasiyana monga kulongedza katundu, zamagetsi ndi magalimoto.Pakupanga tepi yonyamulira ndi chisankho chabwino kwambiri chifukwa cha chuma chake, kulimba komanso kukana kutentha.

Mukamagwiritsa ntchito zinthu za PS ngati zonyamula tepi zopangira, ndikofunikira kumvetsetsa mawonekedwe ake.Choyamba, PS ndi polima amorphous, kutanthauza kuti ilibe mawonekedwe a crystalline.Makhalidwewa amakhudza mawotchi ake ndi matenthedwe katundu, ndiko kuuma, brittleness, opacity ndi kutentha kukana.

Kuphatikizika kwapadera kwa zida za PS kumawapangitsa kukhala abwino pamakampani opanga zamagetsi.Makamaka, kukana kwake kwa chinyezi kumatsimikizira kutetezedwa kwa zida zamagetsi panthawi yoyendetsa kapena kusungirako.Ichi ndichifukwa chake PS zakuthupi ndizosankha zotchuka zonyamula tepi yaiwisi.

Chinthu china chofunikira pazakuthupi za PS ndi mawonekedwe ake.Chifukwa cha kukhuthala kwake kotsika, PS ili ndi mawonekedwe abwino kwambiri, imathandizira kumaliza kwapamwamba komanso nthawi yabwino yopangira popanga zida zonyamula tepi.

PS molding performance
1. Zinthu za amorphous zimakhala ndi chinyezi chochepa, sichiyenera kuuma mokwanira, ndipo sizovuta kuwonongeka, koma zimakhala ndi coefficient yaikulu yowonjezera kutentha ndipo zimakhala zovuta kupsinjika mkati.Ili ndi madzi abwino ndipo imatha kupangidwa ndi makina opangira jekeseni kapena plunger.
2. Ndikoyenera kugwiritsa ntchito kutentha kwakukulu kwa zinthu, kutentha kwa nkhungu, ndi kutsika kwa jekeseni.Kutalikitsa nthawi ya jekeseni kumapindulitsa kuchepetsa kupsinjika kwamkati ndikupewa kuphulika kwa shrinkage ndi deformation.
3. Mitundu yosiyanasiyana ya zipata ingagwiritsidwe ntchito, ndipo chipata chimagwirizanitsidwa ndi gawo la pulasitiki mu arc kuti zisawonongeke gawo la pulasitiki pachipata.Malo otsetsereka ndi aakulu, ndipo ejection ndi yofanana.Makulidwe a khoma la gawo la pulasitiki ndi yunifolomu, ndipo palibe zoyikapo momwe zingathere, monga Zolowetsa ziyenera kutenthedwa.
Mwachidule, zinthu za PS ndi chisankho chabwino kwambiri pazonyamula tepi zopangira chifukwa cha mawonekedwe ake apadera komanso mawonekedwe ake.Monga polima ya thermoplastic, PS ndiyopanda ndalama, yokhazikika komanso yosamva kutentha.Kuphatikiza apo, kukana kwake kwa chinyezi kumapangitsa kukhala koyenera kuteteza zida zamagetsi panthawi yoyendetsa ndi kusunga.

Kumvetsetsa zinthu zakuthupi za PS ndi momwe zimakhudzira mapangidwe ake ndikofunikira kuti mukwaniritse kupanga matepi onyamula.Posankha zida za PS zamtengo wapatali, titha kupanga matepi onyamula amtundu wabwino komanso wochita bwino kwambiri, kuwonetsetsa kuti zida zilizonse zamagetsi zikuyenda bwino.
