Chinyezi ndi kukana kwa UV kwa chinthucho zimapangitsa kuti chikhale chokongola pa ntchito monga mapaipi ndi zolumikizira mapaipi.
PVC yolimba / yopanda pulasitiki
| Kulimbitsa Mphamvu, Zokolola (MPa) | Elongation pa Kupuma (%) | Kulimba (Shore D) | Kutentha kwapang'onopang'ono (°C) | Kuchuluka kwa Kuyaka (UL 94 (1.5 mm)) | mtundu |

Amatha
Mosiyana ndi mapulasitiki ena ambiri auinjiniya, PVC imatha kupakidwa utoto mosavuta kuti ikongoletse komanso kuti ipitirize kukhala ndi moyo wautali panja. Tiyeneranso kudziwa kuti ngakhale kuti mawonekedwe ake amakaniko amakhalabe ofanana, PVC yowonekera bwino imasintha mtundu pakapita nthawi ikakumana ndi dzuwa kapena magwero ena a UV.
Zojambulidwa: PVC ikhoza kupakidwa utoto bola ngati utotowo ulibe zosungunulira zomwe zimawononga polyvinyl chloride. Onetsetsani kuti utoto wanu wapangidwa kuti ugwire ntchito pa PVC popanda kuwononga mphamvu zake zamagetsi.
Monga Makina: PVC imapangidwa mosavuta ndipo imapanga mawonekedwe osalala komanso owala bwino popanda kufunikira ntchito zina zowonjezera.
Malangizo Opangira Zinthu Mosawononga Ndalama
Makina opangira CNC mu PVC amapanga zinthu zopepuka komanso zotsika mtengo. Komabe, malangizo otsatirawa angathandize kuchepetsa ndalama zambiri:
Magulu ang'onoang'ono: PVC imapezeka ngati pepala kapena sheet stock m'makulidwe osiyanasiyana. Konzani kapangidwe kanu kuti mutha kupanga zinthu kuchokera ku kukula kwa sheet iyi ndikuziphatikiza pambuyo pake mu gawo lomaliza. Ma PVC glue ndi osavuta kupeza ndipo angagwiritsidwe ntchito popanga zinthu zovuta kuchokera kuzinthu zingapo zazing'ono pamtengo wotsika.
Mapulasitiki a CNC amatsatira njira zomwezo zopangira zitsulo zopangidwa ndi makina a CNC, choncho gwiritsani ntchito njira zabwino zopangira makina nthawi iliyonse yomwe zingatheke.
