ntchito

PE Pipe imagwiritsidwa ntchito padziko lonse lapansi pama projekiti osiyanasiyana.Kuyambira m'zaka za m'ma 1950, chitoliro chamtunduwu chapereka ubwino waukulu kwa oyang'anira polojekiti ndipo amavotera kwambiri m'mapulogalamu ena pa machitidwe omwe amagwiritsa ntchito zitsulo, simenti kapena zipangizo zina.Nkhaniyi ifotokoza kuti chitoliro cha PE ndi chiyani komanso momwe chimagwiritsidwira ntchito.
Kodi PE pipe ndi chiyani?
Chitoliro cha PE ndi chitoliro chomwe chimapangidwa ndi polyethylene (PE).Mipope iyi imapangidwa ndi zinthu za thermoplastic, zomwe zimapangidwa ndi polymerization ya ethylene.PE chitoliro amapangidwa kudzera njira yotchedwa extrusion, kotero n'zosavuta kupanga mapaipi a kukula kwake.
Mapaipi a PE amayimilira bwino kukakamizidwa, chifukwa chake amagwiritsidwa ntchito pazokakamiza zosiyanasiyana ndipo amapangidwa m'magulu osiyanasiyana.Mutha kupeza chitoliro cha PE chokhala ndi mainchesi mpaka 1200 mm.Zing'onozing'ono zimakhala ndi mainchesi pafupifupi 0.5.
Mutha kugula chitoliro cha PE muutali wowongoka kapena m'makoyilo okulungidwa.Mipope yokhala ndi mainchesi ang'onoang'ono nthawi zambiri imagulitsidwa m'makoyilo pomwe iyo yowongoka kutalika mpaka 40 mapazi, nthawi zambiri imakhala ndi mainchesi akulu.Mapaipi onsewa ndi opepuka ndipo amapereka kusinthasintha koyenera.
Chitoliro cha PE chimadziwikanso ndi mikhalidwe yake ina, monga kulimba komanso moyo wautali.Izi zimapangitsa kukhala chisankho chabwino m'mapulojekiti omwe hardiness ndi chofunikira.Mapaipi a PE amakananso mankhwala, motero amathandizira kuti chakudya zisakhudzidwe ndi poizoni.
Mapaipi akuda amitundumitundu opangidwa ndi polyethylene nthawi zambiri amawonedwa akuyendetsedwa mozungulira kapena pafupi ndi ntchito zamadzi.Mapaipi akuda a PE awa amapangidwa ndi extrusion imodzi.Palinso mapaipi ena omwe amapangidwa ndi ma extrusion awiri, omwenso ndi akuda koma amakhala ndi mizere yamtundu.
