Kagwiritsidwe Pe chitoliro

1. Chitoliro cha migodi cha PE
Pakati pa mapulasitiki onse a zomangamanga, HDPE imavala bwino kwambiri ndipo imawonekera kwambiri. Kutalika kwamolekyulu, momwe zimakhalira zosavomerezeka, ndizoposa zida zambiri zachitsulo (monga chitsulo cha kaboni, chitsulo chosapanga dzimbiri, bronze, ndi zina zambiri). Pansi pa dzimbiri lamphamvu ndi kuvala kwakukulu, moyo wautumiki umakhala nthawi 4-6 kuchokera ku chitoliro chachitsulo komanso nthawi 9 ya polyethylene wamba; Ndipo kutulutsa bwino kumakonzedwa bwino ndi 20%. Lawi lamtundu wa retardant ndi antistatic ndizabwino ndipo zimakwaniritsa zofunikira. Moyo wotsika pansi waposa zaka 20, wokhala ndi maubwino azachuma, kukana, kuvala ndi kukana kawiri.

2. Chitoliro cha zimbudzi cha PE
Chitoliro cha PE chotaya zimbudzi chimatchedwanso kuti high polyethylene pipe, kutanthauza kuti HDPE mu Chingerezi. Mtundu uwu wa chitoliro nthawi zambiri amagwiritsidwa ntchito ngati kusankha koyamba kwa zomangamanga oyang'anira tauni, makamaka ogwiritsidwa ntchito pamakampani opangira zimbudzi. Chifukwa cha kukana kwake kuvala, kukana kwa asidi, kukana dzimbiri, kutentha kwambiri, kukana kuthamanga ndi mawonekedwe ena, pang'onopang'ono idalowa m'malo mwa mapaipi achikhalidwe monga mapaipi azitsulo ndi mapaipi a simenti mumsika, makamaka chifukwa chitolirochi ndi chopepuka kulemera ndi yabwino kukhazikitsa ndikusuntha, ndipo ndiye kusankha koyamba kwa zida zatsopano. Ogwiritsa ntchito ayenera kusamala kwambiri ndi mfundo zotsatirazi posankha mapaipi opangidwa ndi zinthu izi: 1. Samalani ndi kusankha kwa zinthu zopangira mapaipi apulasitiki. Pali mitundu masauzande azinthu zopangira polyethylene, ndipo pali zopangira zotsika mpaka Yuan zikwi zingapo pamsika. Zida zopangidwa ndi zopangidwazi sizingamangidwe, apo ayi, kutaya ntchito kukonzanso kwakukulu. 2. Kusankhidwa kwa opanga mapaipi kudzayang'aniridwa ndi opanga mwamwambo komanso akatswiri. 3. Mukamasankha kugula mapaipi a PE, yang'anani opanga pamenepo kuti muwone ngati ali ndi kuthekera kopanga.

3. Pe chitoliro madzi
Mapaipi a PE opezera madzi ndi omwe amasinthidwa ndi mapaipi achitsulo achikhalidwe ndi ma payipi amadzi akumwa a PVC.
Chitoliro chamagetsi chimakhala ndi vuto linalake, ndipo utomoni wa PE wokhala ndi kulemera kwama molekyulu komanso mawonekedwe abwino, monga utomoni wa HDPE, nthawi zambiri amasankhidwa. LDPE utomoni ali otsika kwamakokedwe mphamvu, osauka kuthamanga kukana, chinthu chimodzimodzi osauka, osauka ooneka enieni bata pa akamaumba ndi kugwirizana zovuta, choncho si abwino monga nkhani ya chitoliro madzi okwanira kuthamanga. Komabe, chifukwa cha ukhondo wake wapamwamba, PE, makamaka utomoni wa HDPE, tsopano ndi chinthu chodziwika bwino popanga mapaipi amadzi akumwa. HDPE utomoni ali otsika Sungunulani mamasukidwe akayendedwe, wabwino fluidity ndi zosavuta processing, kotero Sungunulani index ali osiyanasiyana kusankha, kawirikawiri MI ndi pakati pa 0.3-3g / 10min.
