PVC PIPE AMAGWIRITSA NTCHITO:PVC chitoliro ndi chimagwiritsidwa ntchito zinthu kupanga, makamaka ntchito mipope ngalande, waya ndi chingwe chitetezo mapaipi ndi minda ina. Magwiritsidwe ake enieni ndi awa:
Chitoliro chamadzimadzi: Chitoliro cha PVC nthawi zambiri chimagwiritsidwa ntchito mu ngalande zanyumba. Chifukwa cha kukana kwake kwa dzimbiri, kukana kupanikizika komanso kukana kwa nyengo, ndizoyenera ntchito zosiyanasiyana za ngalande.
Chitoliro choteteza waya ndi chingwe: Chitoliro cha PVC chimagwiritsidwa ntchito ngati chitoliro choteteza mawaya ndi zingwe pamapulojekiti amagetsi kuti mawaya asanyowe ndi dzimbiri, ndikuwonetsetsa kuti mawaya amayenda bwino.
Minda ina: PVC chitoliro amagwiritsidwanso ntchito ulimi ulimi wothirira, makampani mankhwala, mafakitale chakudya ndi minda ina. Amagwiritsidwa ntchito kwambiri chifukwa chosakhala ndi poizoni, osachita dzimbiri komanso zosavuta kukonza.
ZABWINO1. Mapaipi a PVC ndi opepuka, osavuta kunyamula, kunyamula ndi kutsitsa, kupanga, kupulumutsa ntchito.
2. Acid, alkali ndi kukana dzimbiri ndi zabwino, zoyenera pamipopo yamakampani opanga mankhwala.
3. Khoma la chitoliro ndi losalala, lopanda kukana madzimadzi. Coefficient yake ya roughness ndi 0.009 yokha, yomwe ndi yotsika kuposa mapaipi ena. Pansi pa chitoliro chomwecho, kuthamanga kwake kumakhala kwakukulu kuposa zipangizo zina.
4. Imakhala ndi kukana kwabwino kwa madzi, kukana kuthamanga kwakunja ndi kukana kwamphamvu, ndipo ndi yoyenera pamapulojekiti osiyanasiyana a mapaipi.
5. Kusungunula magetsi, kungagwiritsidwe ntchito ngati ngalande ya mawaya ndi zingwe.
6. Zatsimikiziridwa kupyolera mu mayesero a kusungunuka kuti sizimakhudza khalidwe la madzi ndipo pakali pano ndi chitoliro chabwino kwambiri cha mapaipi a madzi apampopi.
NTCHITO YOPHUNZITSIRA:Kapangidwe ka mapaipi a PVC kumaphatikizapo masitepe monga kukonzekera zopangira, kusakaniza, kutumiza ndi kudyetsa, kudyetsa mokakamiza, kutulutsa, kukula, kuzizira, kudula, kuyesa ndi kuyika. ndi
Njira yopangira mapaipi a PVC imayamba ndikukonza zopangira ndi zowonjezera. Pambuyo kusakaniza, zopangira izi zimadyetsedwa mumzere wopanga kudzera mu njira yotumizira ndi kudyetsa. Kenako, zinthu zosakanikirana zimalowa mu conical twin-screw extruder kudzera mu njira yodyetsera mokakamizidwa, pomwe zinthuzo zimatenthedwa ndi kupangidwa ndi pulasitiki, kenako zimapangidwa kudzera mukufa. Chitoliro chopangidwa chimalowa m'manja mwake ndipo chimapangidwa ndi bokosi lopangira vacuum. Panthawi imodzimodziyo, chitolirocho chimakhazikika ndi madzi opopera. Chitoliro chokhazikika chimayenda pa liwiro lofananira pansi pa makina okokera, ndipo imayendetsedwa ndi chipangizo choyezera ndikudula mipope yautali wokonzedweratu ndi machedwe a mapulaneti. Pomaliza, chitoliro chodulidwa chimakulitsidwa ndikuyesedwa ndikuyikidwa ngati chomaliza kuti amalize ntchito yonse yopanga.
