Zigawo zitatu za PVC Pipe Co-extrusion mzere

1. The extruder ntchito wapamwamba kuvala zosagwira aloyi wononga mbiya; mapasa amadya mofanana ndipo ufawo suphatikizana.
2. Kukometsedwa kwa nkhungu za PVC zosanjikiza zitatu, njira yotuluka mkati ndi chrome-yokutidwa ndi kupukutidwa kwambiri, kuvala ndi kugonjetsedwa ndi dzimbiri; ndi manja apadera sizing, mankhwala chitoliro ali mkulu liwiro ndi pamwamba abwino.
3. Kudula makina utenga kasinthasintha clamping chipangizo kuti azolowere osiyana chitoliro diameters, kuthetsa vuto la pafupipafupi m'malo mindandanda yamasewera. Okonzeka ndi mtundu watsopano wa chosinthika choyandama chamfering limagwirira, kukula chamfer akhoza kusintha malinga ndi m'mimba mwake chitoliro ndi khoma makulidwe, kudula ndi chamfering akhoza kuchitidwa sitepe imodzi. Chotsekedwa choyamwa chipangizo, bwino chip kuyamwa zotsatira.

Chitoliro cha PVC ndi chitoliro cha pulasitiki chopangidwa kuchokera ku thermoplastic material polyvinyl chloride (PVC). Chitoliro cha PVC chimagwiritsidwa ntchito kwambiri pamagwiritsidwe ntchito ndi mafakitale ndipo chimabwera m'mitundu yosiyanasiyana. Kupaka mapaipi a PVC nthawi zambiri kumagwiritsidwa ntchito ngati ngalande, madzi, ulimi wothirira, kusamalira mankhwala, machubu olowera mpweya, ntchito yopangira mapaipi ndi zinyalala. Zopezeka za PVC zopangira mapaipi ndi ndandanda 40 PVC, ndandanda 80 PVC, chitoliro cha mipando ya PVC, chitoliro cha CPVC, chitoliro cha zinyalala (DWV), chitoliro chosinthika, chitoliro chomveka cha PVC ndi chitoliro chosungira kawiri.

Ndandanda 40 ndi ndondomeko 80 chitoliro ndi zosunthika mapaipi mbiri yabwino ndipo analembetsa zizindikiro makampani ndi mfundo ntchito masiku ano ambiri. Chitoliro cha PVC cha kalasi ya mipando chimapezeka mumitundu yosiyanasiyana popanda zolembera kapena zolemba ndipo chimakhala ndi mapeto oyera, onyezimira. Mapaipi a DWV amagwiritsidwa ntchito pokonza zinthu zonyansa. Chitoliro cha Flex ndi chitoliro chosinthika cha PVC chogwiritsidwa ntchito pomwe chitoliro cholimba sichili choyenera kapena chothandiza. Kupopera bwino kumalola kuyang'anitsitsa kayendedwe ka madzimadzi ndi khalidwe la chitoliro. Chitoliro chosungitsa kawiri chapangidwa kuti chikwaniritse malamulo amakampani kuti azitha kujambula kutayikira kwadongosolo kapena kulephera pakuwongolera chitetezo kapena pakufunika.

Chitoliro cha PVC chilipo kukula kwake komwe kumayambira 1/8 inchi mpaka mainchesi 24 m'mimba mwake. Zina mwazinthu zodziwika bwino ndi ½ inchi, 1 ½ inchi, 3 inchi, 4 inchi, 6 inchi, 8 inchi ndi 10 inchi PVC chitoliro. PVC mapaipi amatumizidwa mu muyezo 10 mapazi kapena 20 mapazi kutalika. Izi zimapulumutsa ndalama zonse zogwirira ntchito ndipo zimalola kupereka zinthu zotsika mtengo. Tili ndi magawo 5 a mapazi a SCH 40 PVC, SCH 80 PVC ndi mipando ya PVC yomwe imapezeka kuti itumizidwe.

PVC ikagwiritsidwa ntchito kutanthauza chitoliro cha pulasitiki, nthawi zambiri imamveka kuti ndi UPVC (PVC yopanda pulasitiki) popanga. Chitoliro cha UPVC ndi chitoliro cholimba cha pulasitiki ndipo ndi njira yodziwika bwino ya mapaipi a PVC omwe amagwiritsidwa ntchito pomanga. Mapaipi a UPVC amapangidwa popanda zida zopangira pulasitiki zomwe zitha kuwonjezeredwa kuti zinthu za PVC zikhale zosinthika. Chitoliro cha Flex ndi chitsanzo cha PVC yapulasitiki chifukwa cha kusinthasintha kwake ngati payipi.
