Polyethylene utomoni monga zopangira waukulu wa zinthu, pambuyo extrusion akamaumba kotunga madzi chitoliro polyethylene amatchedwa Pe chitoliro madzi.
Zida zopangira chitoliro chamadzi za PE?
Germany Como yopanga. Zipangizozi zimapangidwa ndiukadaulo wapamwamba kwambiri padziko lonse lapansi, wokhala ndi liwiro lalikulu la extrusion, kusungunuka pang'ono, kudula kokha, PLC kuwongolera njira zopangira magwiridwe antchito.
Pe chitoliro kukhazikitsa mulingo wa?
Muyezo National GB / T 13663-2000.
Kodi mtundu wapamwamba wa chitoliro chamadzi a PE ndi chiyani
Mtundu wakutsogolo umakhala wakuda, ndipo ochepa amafunikira zoyera. Thupi lakuda limakhala ndi mzere wama buluu pamtunda.
Kodi malingaliro a chitoliro chamadzi a PE ndi chiyani?

Makhalidwe a chitoliro chamadzi a PE?
(1) Mkulu mphamvu, kwambiri zachilengedwe nkhawa akulimbana kukana, wabwino zokwawa kukana.
(2) Kulimba bwino komanso kusinthasintha, kusinthasintha kwamphamvu pamaziko osagwirizana komanso kusokonekera, ndipo kumatha kukana zivomezi, mphepo zamkuntho ndi malo ena ovuta.
(3) Ili ndi nyengo yabwino yolimbana (kuphatikiza uv kukana) komanso kukhazikika kwanthawi yayitali.
(4) kukana dzimbiri, sipafunika kuchita mankhwala odana ndi dzimbiri, moyo wautali wautumiki.
(5) khoma lamkati ndilosalala, kukana kwamadzi ndikochepa, kufalitsa kwake kumakhala kwakukulu, ndipo mtengo womanga umasungidwa.
(6) Good avale kukana ndi kuvala kukana.
(7) Kutentha kwakanthawi kotsika ndikwabwino, kumatha kutentha -20-40 ℃ kugwiritsa ntchito bwino, zomangamanga sizimakhudzidwa.
(8) Kusungunuka kwamagetsi (kapena kusungunuka kotentha) kulumikizana kumakhala kosavuta komanso kodalirika, kapangidwe kake kosamalira (komwe madzi sangathe kudulidwa).
(9) Ndi abwino kwathunthu kwa miyambo miyambo yomanga njira zomangamanga ndi umisiri watsopano trenchless monga chitoliro jacking, mbali kuboola, akalowa, chitoliro akulimbana ndi kumira m'madzi.
(10) Zopangira za polyethylene zimangokhala ndi mpweya, haidrojeni zinthu ziwiri, zosavulaza thupi.
Kugwiritsa ntchito ukadaulo wapamwamba wa nano antibacterial, olepheretsa kukula kwa ndere, mabakiteriya ndi bowa, ndikobiriwira, kathanzi, koteteza chilengedwe payipi yamadzi akumwa
Zogulitsa:
1. Kulumikizana kodalirika: Mapaipi a madzi a Polyethylene amalumikizidwa ndi kusungunuka kwamagetsi kotentha; Kugwirizana kwa Flange ndi mapaipi ena, kosavuta komanso mwachangu.
Zachiwiri, kutsika kwakanthawi kotsutsana ndi zabwino: kutentha pang'ono kwa polyethylene ndikotsika kwambiri, kumatha kugwiritsidwa ntchito mosamala kutentha -35 ℃ -60 ℃. Mukumanga kwachisanu, chitolirocho sichingagwedezeke chifukwa chakukanika kwa zinthuzo.
Chachitatu, chabwino kukana kukana kwamankhwala: payipi ya HDPE imatha kupilira kuwola kwa zinthu zosiyanasiyana zamankhwala, kupezeka kwa mankhwala m'nthaka sikungabweretse kuwonongeka kulikonse payipi.
Zinayi, kukalamba kukana, moyo wautali wautumiki: chitoliro cha polyethylene chokhala ndi kufalitsa kofananira kwa mpweya wakuda chikhoza kusungidwa panja kapena kugwiritsidwa ntchito kwa zaka 50, sichidzawonongeka ndi ma radiation a ultraviolet.
Zisanu, kumulowetsa wabwino: KUSINTHA kwa payipi ya HDPE kumapangitsa kuti kukhale kosavuta kupindika, ukadaulo umatha kudutsa zopinga posintha kolowera kwa payipi, nthawi zambiri, kusinthasintha kwa payipi kumatha kuchepetsa kuchuluka kwa mapaipi ndikuchepetsa mtengo wopangira.
Kutsika kotsika: CHIKWANGWANI cha HDPE chimakhala ndi mawonekedwe osalala amkati komanso choyezera chokwanira cha Manning cha 0.009. Maonekedwe osalala komanso osamatira a mapaipi a HDPE amalola kuthekera kopitilira kuposa kuyerekezera kwamatayala, pomwe kumachepetsa kutaya kwa madzi ndi kumwa madzi.
Zisanu ndi ziwiri, zosavuta kusamalira: chitoliro cha HDPE ndi chopepuka kuposa chitoliro cha konkriti, chitoliro chachitsulo ndi chitoliro chachitsulo, chosavuta kusamalira ndikuyika, mtengo wogwirizira ntchitoyi udachepetsedwa.
Njira zisanu ndi zitatu, zomanga zosiyanasiyana: mapaipi amadzi a HDPE, kuwonjezera pa njira zokumba zakale, komanso amatha kugwiritsa ntchito ukadaulo watsopano wosasunthika monga kupangira pomba, kubowola mbali, kulumikizana, kumanga mapaipi, kotero ntchito ya payipi ya HDPE ndi mochuluka kwambiri.
