HDPE resin rau cov yeeb nkab ntau lawm
HDPE cob rau cov yeeb nkab ntau lawm,
HDPE resin rau cov kav dej, HDPE resin yeeb nkab qib, HDPE resin tsum,
HDPE yeeb nkab qib muaj dav lossis bimodal faib ntawm molecular hnyav.Nws muaj zog creep kuj thiab zoo sib npaug ntawm rigidity thiab toughness.Nws yog ruaj heev thiab muaj tsawg sag thaum ua tiav.Cov kav dej uas tsim los ntawm cov khoom siv no muaj lub zog zoo, rigidity thiab kev cuam tshuam tsis zoo thiab cov cuab yeej zoo ntawm SCG thiab RCP.
Cov resin yuav tsum tau muab khaws cia rau hauv ib qho chaw qhuav, qhuav warehouse thiab deb ntawm hluav taws thiab tshav ntuj ncaj qha.Nws yuav tsum tsis txhob muab tso rau hauv qhov qhib cua.Thaum lub sij hawm kev thauj mus los, cov khoom yuav tsum tsis txhob raug tshav ntuj los yog nag thiab yuav tsum tsis txhob raug thauj nrog xuab zeb, av, seem hlau, thee lossis iav.Kev thauj mus los ua ke nrog cov tshuaj lom, corrosive thiab flammable yog nruj me ntsis txwv.
Daim ntawv thov
HDPE yeeb nkab qib tuaj yeem siv rau hauv kev tsim cov kav dej siab, xws li cov kav dej siab, cov kav dej roj thiab lwm cov kav dej.Nws kuj tseem siv tau los ua cov kav dej tsis muaj zog xws li ob-phab ntsa corrugated kav, hollow-wall winding kav, silicon-core kav, kav dej ua liaj ua teb thiab aluminiumplastics compound pipes.Tsis tas li ntawd, los ntawm reactive extrusion (silane cross-linking), nws tuaj yeem siv los ua cov kav dej sib txuas polyethylene (PEX) rau kev muab dej txias thiab dej kub.
Qib thiab tus nqi raug
HDPE yog lub siab crystallinity, uas tsis yog-polar thermoplastic resin.Cov tsos ntawm thawj HDPE yog milky dawb, ib tug tej degree ntawm translucency nyob rau hauv nyias seem.PE muaj kev tiv thaiv zoo rau feem ntau cov tshuaj hauv tsev thiab kev lag luam.Qee hom tshuaj muaj peev xwm ua rau cov tshuaj corrosion, xws li corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) thiab halogenated hydrocarbons (carbon tetrachloride).Lub polymer yog non-hygroscopic thiab muaj qhov ua haujlwm zoo, uas tuaj yeem siv rau kev ntim khoom.HDPE muaj cov khoom siv hluav taws xob zoo heev, tshwj xeeb tshaj yog lub zog dielectric ntawm rwb thaiv tsev, yog li nws tsim nyog rau cov xaim thiab cable.Cov chav kawm nruab nrab mus rau siab molecular hnyav muaj kev cuam tshuam zoo heev ntawm chav tsev kub thiab txawm tias qhov kub thiab txias li -40F.
Cov teeb meem xav tau kev saib xyuas hauv daim ntawv thov ntawm HDPE yeeb nkab
1, sab nraum zoov qhib cua tso, qhov twg muaj hnub ci, nws raug nquahu kom ua qhov ntsuas vaj tse.
2. Cov kav dej HDPE faus, cov kav dej DN≤110 tuaj yeem ntsia tau rau lub caij ntuj sov, me ntsis nab tso, DN≥110 cov kav dej vim muaj av txaus tiv thaiv, tuaj yeem tiv taus thermal stress, tsis tas yuav khaws cov yeeb nkab ntev;Thaum lub caij ntuj no, tsis tas yuav khaws cov yeeb nkab ntev.
3, HDPE pipeline installation, yog tias qhov chaw ua haujlwm tsawg dhau (xws li: cov kav dej zoo, kev tsim kho qab nthab, thiab lwm yam), yuav tsum siv hluav taws xob fusion txuas.
4. Thaum lub qhov (socket) kub yaj txuas nrog, cov cua kub yuav tsum tsis txhob siab dhau los yog ntev heev, thiab qhov kub yuav tsum tau tswj ntawm 210 ± 10 ℃, txwv tsis pub nws yuav ua rau ntau dhau molten slurry extruded nyob rau hauv qhov chaw thiab txo cov sab hauv. txoj kab uas hla ntawm dej;Cov yeeb nkab haum lossis cov yeeb nkab sib txuas yuav tsum huv si thaum lub qhov (socket) tso, txwv tsis pub nws yuav ua rau lub qhov (socket) tawg thiab tawg;Nyob rau tib lub sijhawm, kev saib xyuas yuav tsum tau them nyiaj los tswj lub kaum sab xis thiab kev taw qhia ntawm cov yeeb nkab fittings kom tsis txhob rov ua haujlwm dua.
5, kub yaj pob tw txuas, qhov hluav taws xob yuav tsum tau nruab nrab ntawm 200 ~ 220V, yog tias qhov hluav taws xob siab dhau lawm, yuav ua rau cov cua sov phaj kub siab dhau, qhov hluav taws xob tsawg dhau, ces lub tshuab taub qab tsis tuaj yeem ua haujlwm ib txwm;Lub pob tw yuav tsum tau ua raws li lub interface;txwv tsis pub, lub pob tw cheeb tsam tsis txaus, lub zog ntawm cov vuam sib txuas tsis txaus, thiab flange tsis yog.Thaum lub phaj cua sov yog rhuab, lub interface ntawm cov yeeb nkab tsis huv, los yog lub phaj cua sov muaj impurities xws li roj thiab sediment, uas yuav ua rau lub interface tawg thiab xau.Lub sijhawm cua sov yuav tsum tau tswj kom zoo.Lub sijhawm cua sov luv thiab lub sijhawm nqus cua tsis txaus ntawm cov yeeb nkab yuav ua rau lub vuam seam me me dhau.Lub sij hawm cua sov ntev dhau lawm yuav ua rau cov vuam seam loj dhau thiab tuaj yeem tsim cov vuam virtual.
