Phaephe ea HDPE bakeng sa Phepelo ea Metsi a Nooang
Likarolo tsa Sehlahisoa
1. Bohloeki le polokeho
E latela maemo a bohloeki ba metsi a nooang a GB/T 17219, ha e na chefo ebile ha e na lintho tse eketsang tšepe e boima, e qoba tšilafalo ea bobeli.
2. E tenyetseha ebile e bonolo
Moralo oa koili o loketse ho tsamaisoa le ho beoa, 'me o loketse haholo phepelo ea metsi ea terminal ea bophara bo bonyenyane (DN20-DN63) kapa nosetso e sa reroang.
3. Ho hanyetsa ts'enyeho le ho hanyetsa mocheso o tlase
E hanela ts'enyeho e mahareng ea lik'hemik'hale, mocheso o sebetsang: -20℃ ho isa ho 40℃ (mefuta e meng ea HDPE e ka atolosoa ho isa ho -60℃ ho isa ho 60℃)
Maemo a ka Sehloohong a Kopo
Phepelo ea metsi malapeng le sechabeng: Phano ea metsi a nooang ea seteishene, joalo ka litsamaiso tsa tlhoekiso ea metsi malapeng le liphaephe tsa metsi a nooang ka kotloloho libakeng tsa bolulo
Nosetso ea marotholi a temo/mochini o fafatsang ka micro-spray: Likhoele tse nyane tse bophara bo nyane li loketse makala a theipi ea ho nosetsa ka marotholi kapa litsamaiso tsa ho fafatsa ka mocheso oa ntloana.
Phepelo ea metsi ea tšohanyetso: Liphaephe tsa metsi a nooang tsa nakoana tse kentsoeng ka potlako (joalo ka maemong a thuso ea likoluoa)
Lintlha tsa Bohlokoa bakeng sa Khetho le Kaho
1. Khetho ea thepa
HDPE (sehlopha sa PE100) e ratoa haholo kaha e na le matla a phahameng le khanyetso e ntle ea khatello (ho fihlela ho 1.6MPa).
2. Tlhahlobo ea boleng
Netefatsa hore ponahalo e boreleli ntle le dipululana mme mmala o tshwana (botsho bo na le carbon black bakeng sa ho hanyetsa UV, mme bosweu ke mmala wa tlhaho).
3. Mokhoa oa khokahano
Bakeng sa DN≤63mm, sokete e qhibilihang ka ho chesang kapa khokahano ea electrofusion e amoheloa ho netefatsa ho tiisoa ha sebopeho
Litlhaloso tse tloaelehileng
Bophara: DN20, DN25, DN32, DN40, DN50, DN63
Bolelele ba koili: Hangata limithara tse 200 ka koili, e ka fetoloang
