PVC kwa Pipe Fittings
PVC (polyvinyl chloride) ndi vinyl polima.Pansi pa chikhalidwe choyenera, pang'ono imalepheretsa klorini kuti isagwirizane ndi haidrojeni.Amatero kupanga hydrochloric acid (HCl).Pagululi ndi acidic ndipo lingayambitse dzimbiri.Chifukwa chake, ngakhale ili ndi zinthu zambiri zofunika, PVC ndiyowononga.Izi zimabweretsa zovuta zina pakukonza ndi kugwiritsa ntchito kwake.PVC imakana kwambiri madzi ndi zakumwa zambiri zatsiku ndi tsiku.Imasungunuka mu tetrahydrofuran, cyclohexane, ndi cyclopentanone.Chifukwa chake mukamagwiritsa ntchito zida za PVC ganizirani zamadzimadzi omwe amatsikira kukhetsa.
Kuti akwaniritse zofunikira zosiyanasiyana, mapaipi amayenera kupindika m'njira zosiyanasiyana komanso mosiyanasiyana.Izi zitha kukhala kusokoneza kuyenda konse kapena gawo lakuyenda.Zopangira mapaipi azolowera kulumikiza mapaipi pamakona osiyanasiyana.Amatha kulumikiza mapaipi awiri mpaka 4 pamodzi.Chitoliro ndi zoikamo zake zimagwiritsidwa ntchito m'njira zambiri.Zitsanzo ndi ngalande zachimbudzi, madzi, ndi ulimi wothirira.Kukhazikitsidwa kwa mapaipi a PVC kunali kusintha kwakukulu m'nyumba ndi mafakitale.Masiku ano nyumba ndi mafakitale ambiri akusintha kuchoka ku mapaipi achitsulo kupita ku mapaipi a PVC.Mapaipi a PVC amakhala nthawi yayitali.Sachita dzimbiri ndipo amatha kupirira zovuta zotuluka.Chifukwa cha njira zazikulu zopangira monga kuumba jekeseni, ndizotsika mtengo.M'munsimu muli zitsanzo za jekeseni wowumbidwa mapaipi.
Momwe zopangira mapaipi a PVC amapangidwira
Zopangira PVC zimapangidwa ndi jekeseni wothamanga kwambiri.Njira yopangira jekeseni imayamba ndi PVC mu mawonekedwe a granules kapena pellets.Mosiyana ndi extrusion mosalekeza, akamaumba ndi mobwerezabwereza cyclic ndondomeko, kumene "kuwombera" zinthu amaperekedwa ku nkhungu mkombero uliwonse.
PVC, mawonekedwe amtundu wa granular, ndi mphamvu yokoka yomwe imadyetsedwa kuchokera ku hopper yomwe ili pamwamba pa jekeseni, kulowa mu mbiya yomwe imakhala ndi zomangira.Mgolowu umayimbidwa ndi kuchuluka kofunikira kwa pulasitiki ndi zozungulira zozungulira ndikutumiza zinthuzo kutsogolo kwa mbiyayo.Malo a screw amayikidwa kuti akhale "kukula kwa kuwombera".Panthawi imeneyi, kupanikizika ndi kutentha "pulasitiki" zinthu, zomwe tsopano zasungunuka, zikuyembekezera jekeseni mu nkhungu.
Zonsezi zimachitika panthawi yozizira ya kuwombera koyambirira.Pambuyo pa nthawi yoikidwiratu nkhungu imatsegulidwa ndipo chomaliza chopangidwacho chidzachotsedwa mu nkhungu.
Chikombolecho chimatseka ndipo pulasitiki yosungunuka kutsogolo kwa mbiya imabayidwa pansi pa kupsyinjika kwakukulu ndi screw yomwe tsopano ikugwira ntchito ngati plunger.Pulasitiki imalowa mu nkhungu kuti ipange chotsatira chotsatira.
Pambuyo jekeseni, recharge imayamba pomwe choyikapo chimadutsa m'nyengo yozizira.
Za PVC jakisoni Kuumba
Popeza katundu wa PVC zinthu zina ndizofunikira pakuumba kwawo jakisoni.Kupanga jakisoni kwa PVC kumafuna kuti iwonekere kutentha kwambiri.Chifukwa cha mankhwala ndi mawonekedwe a PVC, izi zitha kubweretsa zovuta panjirayo.Izi ndi zina mwazofunikira pakumangirira kwa jekeseni za PVC payipi zopangira.
Zinthu za Mold
Njira yabwino yopangira nkhungu ya PVC ndi anti-corrosion stainless steel.Izi ziyenera kukhala bwino opukutidwa anaumitsa chitsulo.Pali kuthekera kwakukulu kotulutsa HCl panthawi yopanga zida zapaipi ya PVC.Izi ndizovuta kwambiri ndi PVC yomwe ili m'malo osungunuka.Klorini iliyonse mu mawonekedwe a mpweya imatha kukhazikika ikagunda nkhungu.Izi zimapangitsa nkhunguyo kuti iwonongeke.Ngakhale zidzachitika, kugwiritsa ntchito zitsulo zapamwamba kumachepetsa mwayi.Izi zimawonjezera moyo wothandiza wa nkhungu.Choncho musapite wotchipa pankhani kusankha nkhungu zinthu.Popanga jakisoni wa PVC, pitani pazitsulo zabwino kwambiri zomwe mungapeze.
Mould Design kwa PVC payipi zovekera
Kupanga nkhungu kwa mawonekedwe olimba olimba ndizovuta.Kupanga nkhungu yopangira mapaipi a PVC kumakhala kovuta kwambiri.Mphuno ya nkhungu si njira yosavuta yodulidwa kuchokera ku mawonekedwe olimba ndi zitseko.Nkhungu ndi msonkhano wovuta kwambiri.Zimafunika katswiri pakupanga nkhungu ndi kupanga nkhungu.Kuyang'ana mawonekedwe a chitoliro choyenera.Mwachitsanzo, tenga chitoliro cha chigongono.Msonkhano wa nkhungu umapangidwa m'njira yomwe imalola kudzazidwa kwa thupi la chitoliro.Koma izi zimachitika popanda kudzaza dera lopanda kanthu.Izi zimachitika poganizira za ejection ndi kumasulidwa kwazinthu.Zopangidwe zofananira zimafunikira nkhungu yokhala ndi magawo angapo.Izi zitha kukhala mpaka magawo 4 a nkhungu.Izi ndizosiyana ndi zolimba zolimba zomwe zimatha kupangidwa ndi nkhungu yokhala ndi magawo awiri.Chifukwa chake pakuyika kwa chitoliro cha PVC funani mainjiniya a nkhungu odziwa zambiri ndi nkhungu yamtunduwu.M'munsimu muli chitsanzo cha nkhungu yokwanira chitoliro cha PVC.
