Posachedwapa, ndinkalankhula ndi makasitomala angapo omwe amagwira ntchito yokonza mapaipi. Ndikuona kuti posankha chitoliro chamkati nthawi zonse amadabwa ndi funso ili: Chitoliro Chopangidwa ndi Polyurethane ndiChitoliro Chopangidwa ndi Polypropylene, ndi iti yabwino? Zipangizo zonse zoyambira ndi Spiral Seam Welded Pipe, koma zipangizo zamkati mwa lining ndizosiyana, ndipo magwiridwe antchito ndi mtengo wake ndi zosiyana kwambiri.
Lero, potengera chitsanzo chenicheni cha Cangzhou Spiral Steel Pipe Factory, ndifotokoza bwino nkhaniyi.
Tiyeni tiyambe ndi gawo lapansi. Ili ndiye maziko.
Kaya mkati mwake mwapangidwa ndi PU kapena PP, maziko ake nthawi zonse amakhalaSpiral Seam welded chitoliroPali opanga ambiri ku Cangzhou omwe amapanga izi, koma Cangzhou Spiral Steel Pipes Group Co., Ltd. yokha ndi yomwe ingakwaniritse kukula kwakukulu. Kampaniyi idakhazikitsidwa mu 1993, yokhala ndi malo okwana masikweya mita 350,000 ku Cangzhou, yokhala ndi chuma chonse cha mayuan 680 miliyoni ndi antchito 680. Imatha kupanga matani 400,000 a mapaipi achitsulo chozungulira pachaka, ndi phindu lochokera ku mayuan 1.8 biliyoni - kukula kumeneku ndikofunikira kwambiri m'makampani am'nyumba.
Koma chomwe chimatsimikizira nthawi ya moyo wa payipi ndi dongosolo lopaka utoto la magawo atatu.
Anthu ambiri amangoyang'ana kwambiri mkati mwa denga, koma amanyalanyaza njira zitatu zofunika kwambiri: pulasitala, guluu, ndi gawo lakunja loletsa dzimbiri. Tiyeni tikambirane chimodzi ndi chimodzi.
Gawo 1: Epoxy Resin Primer
Izi zimapopedwa ngati ufa ndipo makulidwe ake sayenera kupitirira ma micrometer 60. Musanyoze gawo lochepa ili. Ndi lomwe limayambitsa kugwirizana ndi chitoliro chachitsulo. Ngati pulasitala sinapangidwe bwino, ngakhale itamatirira kwambiri pamwamba, sidzathandiza.
Gawo lachiwiri: guluu wa PE
Gawoli likhoza kupopedwa kapena kutulutsidwa. Kukhuthala kochepa ndi ma micrometer 140. Pali tsatanetsatane waukadaulo wofunika kudziwa apa: Mphamvu ya peel yofunikira pakupopedwa kwa ufa ndi njira zotulutsira ndi zosiyana. Mukagula, onetsetsani kuti mwafunsa wogulitsayo njira yomwe amagwiritsa ntchito. Kupanda kutero, ngati mungolichotsa pamalopo, lidzachotsa khungu, zomwe zingakhale zovuta.
Gawo lachitatu: Chophimba chakunja cha polyethylene
Chigawochi ndi chokhuthala kwambiri ndipo chimapangidwa kudzera mu sintering kapena potulutsa kudzera mu chubu kapena pepala. Pambuyo popaka, chiyenera kuziziritsidwa; apo ayi, chidzawonongeka chikakanizidwa panthawi yonyamula. Kukhuthala konse kwa chophimba kumasiyana malinga ndi kukula kwa chitoliro. Ngati chitolirocho chikakwiriridwa pansi pa nthaka kapena kudzazidwa ndi makina ambiri, makulidwe osachepera a chitolirocho ayenera kuwonjezeredwa ndi mamilimita ena 0.7. Mtengo weniweni nthawi zambiri umaperekedwa patebulo ndi wopanga, ndipo mutha kusankha motsatira.
Kubwerera ku funso loyambirira: PU lining kapena PP lining?
Mwachidule, nayi upangiri wozikidwa pa zomwe zachitika: Mapaipi okhala ndi polyurethane ali ndi mphamvu yolimba yotha kutha ndipo ndi oyenera kunyamula zinthu zokhala ndi tinthu tolimba, monga matope ndi madzi otayira;Mapaipi okhala ndi polypropyleneali ndi mphamvu yolimba yolimbana ndi kutentha komanso dzimbiri la mankhwala, ndipo ndi oyenera kugwiritsa ntchito mankhwala komanso kutentha kwambiri.
Ngati bajeti ya polojekiti ilola, n'zothekanso kulankhulana ndi wopanga kuti apange njira yolumikizirana. Komabe, chofunikira ndichakuti mtundu wa zinthu zoyambira ndi utoto wa Spiral Seam Welded Pipe wokhala ndi zigawo zitatu ziyenera kukhala zovomerezeka. Chifukwa chomwe Cangzhou Spiral Steel Pipe Factory yakhala ikulimba mumakampani awa kwa zaka zambiri, kwenikweni, ndikuti imayang'anira njira yonseyo - kupukutira zinthu zoyambira, kugwiritsa ntchito utoto, ndikusonkhanitsa mkati - zomwe ndizodalirika kwambiri kuposa kudalira ogulitsa omwe amalumikiza zinthu zawo.
Palibe yankho lolondola posankha chitoliro, koma pali njira zolondola. Ndikukhulupirira kuti nkhaniyi ingakuthandizeni kupewa njira zina zosafunikira posankha pakati pa PU ndi PP.
