Kugwiritsa Ntchito PE Pipe

1. PE migodi chitoliro
Pakati pa mapulasitiki onse a uinjiniya, HDPE ndiyomwe imakhala yolimba kwambiri ndipo ndiyowoneka bwino kwambiri.Kulemera kwa mamolekyu kumapangitsa kuti zinthuzo zisavale, ngakhale kupitirira zitsulo zambiri (monga carbon steel, chitsulo chosapanga dzimbiri, bronze, etc.).Pansi pa zikhalidwe za dzimbiri zamphamvu ndi kuvala kwakukulu, moyo wautumiki ndi 4-6 nthawi ya chitoliro chachitsulo ndi 9 nthawi ya polyethylene wamba;Ndipo mphamvu yotumizira imakula ndi 20%.Zolepheretsa moto ndi antistatic katundu ndi zabwino ndipo zimakwaniritsa zofunikira.Moyo wautumiki wapansi wadutsa zaka 20, zopindulitsa kwambiri pazachuma, kukana kukhudzidwa, kukana kuvala komanso kukana kawiri.

2. PE chimbudzi chimbudzi
PE chitoliro cha kutaya zimbudzi amatchedwanso mkulu kachulukidwe polyethylene chitoliro, kutanthauza HDPE mu English.Chitoliro chamtunduwu nthawi zambiri chimagwiritsidwa ntchito ngati chosankha choyamba cha uinjiniya wa tauni, womwe umagwiritsidwa ntchito makamaka m'makampani ochizira zimbudzi.Chifukwa cha kukana kwake kuvala, kukana kwa asidi, kukana kwa dzimbiri, kukana kutentha kwakukulu, kukana kuthamanga kwapamwamba ndi makhalidwe ena, pang'onopang'ono m'malo mwa mipope yachikhalidwe monga mipope yachitsulo ndi mapaipi a simenti pamsika, makamaka chifukwa chitoliro ichi ndi chopepuka. komanso yabwino kukhazikitsa ndi kusuntha, ndipo ndiye kusankha koyamba kwa zida zatsopano.Ogwiritsa ntchito ayenera kumvetsera kwambiri mfundo zotsatirazi posankha mapaipi opangidwa ndi nkhaniyi: 1. Samalani kwambiri posankha zipangizo zamapaipi apulasitiki.Pali masauzande masauzande a zida za polyethylene, ndipo pali zopangira zotsika mpaka ma yuan masauzande angapo pa tani pamsika.Zopangidwa ndi izi sizingamangidwe, apo ayi, kutayika kwa ntchito kudzakhala kwakukulu.2. Kusankhidwa kwa opanga mapaipi kudzakhala pansi pa opanga ovomerezeka ndi akatswiri.3. Posankha kugula mapaipi a PE, yang'anani opanga pomwepo kuti muwone ngati ali ndi mphamvu zopangira.

3. Chitoliro chamadzi cha PE
Mapaipi a PE operekera madzi ndi omwe amasinthidwa ndi mapaipi achitsulo achikhalidwe ndi mapaipi amadzi akumwa a PVC.
Chitoliro choperekera madzi chiyenera kukhala ndi kupanikizika kwina, ndipo utomoni wa PE wokhala ndi kulemera kwakukulu kwa mamolekyu ndi katundu wabwino wamakina, monga HDPE resin, nthawi zambiri amasankhidwa.Utoto wa LDPE uli ndi mphamvu zotsika kwambiri, kukana kupanikizika, kusakhazikika bwino, kusasunthika kwapang'onopang'ono pakumangirira komanso kulumikizana movutikira, chifukwa chake sizoyenera ngati chitoliro chamadzi.Komabe, chifukwa chaukhondo wake wapamwamba, PE, makamaka utomoni wa HDPE, wakhala chinthu chodziwika bwino popanga mapaipi amadzi akumwa.Utomoni wa HDPE uli ndi mawonekedwe otsika osungunuka, madzi abwino komanso osavuta kukonza, choncho ndondomeko yake yosungunuka imakhala ndi zosankha zambiri, kawirikawiri MI ili pakati pa 0.3-3g / 10min.
