Liphaephe le lisebelisoa tsa PP-R li thehiloe ho polypropylene e sa sebetseng e le thepa e ka sehloohong e tala 'me e hlahisoa ho latela GB / T18742. Polypropylene e ka aroloa ka PP-H (homopolymer polypropylene), PP-B (block copolymer polypropylene), le PP-R (random copolymer polypropylene). Mochini oa lipeipi o entsoeng ka marako a mabeli o phetha karolo ea bohlokoa tlhahisong ea liphaephe. PP-R ke thepa ea khetho bakeng sa liphaephe tsa polypropylene bakeng sa metsi a chesang le a batang ka lebaka la ho hanyetsa nako e telele khatello ea hydrostatic, botsofali ba nako e telele bo sa keneleng mocheso oa oksijene le ho sebetsa le ho bōptjoa.
PP-R tube ke eng?
Pipe ea PP-R e boetse e bitsoa pipe ea polypropylene ea mefuta e meraro. E amohela ka tšohanyetso copolymer polypropylene hore e ntšetsoe ka phala, ebe e etsoa ka ente ka phala. Ke mofuta o mocha oa sehlahisoa sa liphaephe tsa polasetiki tse ntlafalitsoeng le ho sebelisoa Europe mathoasong a lilemo tsa bo-1990. PP-R e hlahile ho elella bofelong ba lilemo tsa bo-80, e sebelisa mokhoa oa khase oa copolymerization ho etsa hoo e ka bang 5% PE ka har'a ketane ea molek'hule ea PP ka mokhoa o sa reroang le ka mokhoa o ts'oanang oa polymerization (copolymerization e sa reroang) ho fetoha moloko o mocha oa lisebelisoa tsa liphaephe. E na le phello e ntle ea ho hanyetsa le ts'ebetso ea nako e telele ea creep.
Liphaephe tsa PP-R ke life? Pipe ea PP-R e na le likarolo tse latelang tsa mantlha:
1.e seng chefo le bohloeki. Limolek'hule tse tala tsa PP-R ke carbon le hydrogen feela. Ha ho na lintho tse kotsi le tse chefo. Li hloekile ebile lia tšepahala. Ha li sebelisoe feela liphaepheng tsa metsi a chesang le a batang, empa hape li sebelisoa mekhoeng e hloekileng ea metsi a nooang.
2.Ho boloka mocheso le ho boloka matla. Thermal conductivity ea PP-R pipe ke 0.21w / mk, e leng feela 1/200 ea phala ea tšepe.
3.ho hanyetsa mocheso o motle. Sebaka sa ho nolofatsa vicat ea PP-R tube ke 131.5 ° C. Mocheso o moholo oa ho sebetsa o ka fihla ho 95 ° C, o ka finyellang litlhoko tsa mekhoa ea metsi a chesang ka ho haha litlhaloso tsa metsi le metsi.
4.Bophelo bo bolelele ba tšebeletso. Bophelo bo sebetsang ba phala ea PP-R bo ka fihla lilemo tse fetang 50 tlas'a mocheso oa ho sebetsa oa 70 ℃ le khatello ea ho sebetsa (PN) 1.OMpa; bophelo ba tšebeletso ea mocheso o tloaelehileng (20 ℃) e ka fihla lilemo tse fetang 100.
5.Easy tlhomamiso le kgokelo e ka tšeptjoang. PP-R e na le ts'ebetso e ntle ea welding. Liphaephe le li-fittings li ka kopanngoa ke ho qhibiliha ho chesang le motlakase oa motlakase, oo ho leng bonolo ho o kenya le o ka tšeptjoang ka manonyeletso. Matla a likarolo tse kopantsoeng a maholo ho feta matla a phala ka boeona.
6.Materials ka recycled. Litšila tsa PP-R lia hloekisoa le ho siloa le ho sebelisoa hape bakeng sa tlhahiso ea liphaephe le liphaephe. Palo ea lisebelisoa tse tsosolositsoeng ha e fete 10% ea chelete eohle, e sa ameng boleng ba sehlahisoa.
Libaka tse ka sehloohong tsa ts'ebeliso ea liphaephe tsa PP-R ke life?
1. Lits'ebetso tsa moaho tse batang le tsa metsi a chesang, ho kenyeletsoa le litsamaiso tse futhumatsang tse bohareng;
2.Mokhoa oa ho futhumatsa mohahong, ho kenyeletsa fatše, mahlakoreng le tsamaiso ea ho futhumatsa e khanyang;
3.Sistimi ea phepelo ea metsi a hloekileng bakeng sa ho noa ka kotloloho;
4.Bohareng (bohareng) tsamaiso ea moea ea moea;
5.Litsamaiso tsa lipeipi tsa indasteri bakeng sa ho tsamaisa kapa ho ntša mecha ea litaba ea lik'hemik'hale.
