Umbhobho weplastiki we-PE Linear
Ukusebenza: Ubushushu bokusebenza: -25℃~ + 75 idigri (ubona bushushu bokusebenza bepolyethylene elungisiweyo: 105 degree)
Uxinzelelo oluphakathi lokusebenza: uxinzelelo oluhle yi-2.5MPa kunye noxinzelelo olubi yi-75 KPa
Ukumelana nokubola: i-asidi ye-nonoxidation (efana ne-hydrochloric acid, i-hydrochloric acid, i-dilute sulfuric acid, i-hydrofluoric acid), i-dilute nitric acid, isisombululo se-alkali kunye netyuwa, kodwa ayinakumelana nokubola kwe-nitric acid egxininisiweyo, i-sulfuric acid egxininisiweyo kunye nezinye ii-oxidants ezinamandla. Ukumelana nokugqwesa okulungileyo kwi-solvents eziphilayo kunye nobushushu obuqhelekileyo.
Usetyenziso oluqhelekileyo: lulungele ukuthuthwa okuphakathi kolwelo oludlekayo, olulungele ngakumbi ukuthuthwa kwamanzi asekhaya kunye nokusela amanzi abandayo nabandayo, ukuhanjiswa kwamanzi, akuchaphazeli umgangatho wamanzi, ngokuhambelana neemfuno zokucoceka kokutya, ukuxhathisa ukunxiba okuphezulu kombhobho we-polyethylene woxinaniso lunokusetyenziswa ngokubanzi ukuthuthwa kolwelo oluludaka olufana namalahle, intsimbi ekrwada. Isetyenziswa kakhulu kwiimveliso zepetrochemical amanzi ombane ukukhuselwa kokusingqongileyo kunye namanye amashishini.
⑴ Uxhulumaniso oluthembekileyo: inkqubo yepayipi ye-polyethylene idibaniswe yimodi yombane yokunyibilika kwe-thermal, kwaye amandla okudibanisa aphezulu kunomzimba wombhobho.
⑵ Okulungileyo okuphantsi-ukuxhathisa impembelelo yobushushu: iqondo eliphantsi{1}}lobushushu bobushushu be-embrittlement ye-polyethylene liphantsi kakhulu, elinokusetyenziswa ngokukhuselekileyo kuluhlu lobushushu lwe-60-60 degree. Ekwakhiweni kwebusika, ngenxa yempembelelo entle yokuchasana kwezinto, i-pipe brittle cracking ayiyi kwenzeka.
⑶ Ukumelana nokuqhekeka koxinzelelo olulungileyo: I-HDPE inobuntununtunu obuphantsi besithuba, amandla aphezulu okucheba kunye nokuxhathisa okugqwesileyo okugqwesileyo, ukumelana noxinzelelo lokusingqongileyo nako kubalaseleyo.
⑷ Ukumelana nokuthotywa kweekhemikhali ezilungileyo: umbhobho we-HDPE unokuxhathisa ukubola kwamajelo amaninzi eekhemikhali, kwaye imichiza ekhoyo emhlabeni ayisayi kubangela ukuthotywa kombhobho. I-Polyethylene yi-insulator yombane, engaboli, i-rust okanye i-electrochemical corrosion; ayikhuthazi ukukhula kwe-algae, ibhaktheriya okanye i-fungi.
⑸ Ukumelana nokuguga, ubomi benkonzo ende: umbhobho we-polyethylene oqulethe i-2-2.5% yokusabalalisa okufanayo kwekhabhoni emnyama ingagcinwa emoyeni wangaphandle okanye isetyenziswe iminyaka engama-50, ngaphandle komonakalo ngenxa yemitha ye-ultraviolet.
⑹ Ukumelana nokunxiba okufanelekileyo: uvavanyo oluthelekisayo lokumelana nombhobho we-HDPE kunye nombhobho wentsimbi lubonisa ukuba ukuxhathisa kokunxiba kombhobho we-HDPE kuphindwe ka-4 kunombhobho wentsimbi. Kwintsimi yokuthutha udaka, imibhobho ye-HDPE inokumelana nokunxiba okungcono xa kuthelekiswa nemibhobho yensimbi, oku kuthetha ukuba iipayipi ze-HDPE zinobomi obude benkonzo kunye noqoqosho olungcono.
⑺ Ukuguquguquka okulungileyo: ukuguquguquka kombhobho we-HDPE kwenza kube lula ukugoba, ubunjineli bunokutshintsha isalathiso sombhobho ojikeleze imiqobo, kwiimeko ezininzi, ukuguquguquka kombhobho kunokunciphisa ubungakanani bokufakelwa kwemibhobho kunye nokunciphisa iindleko zokufakela.
⑻ Ukumelana nokuhamba okuncinci: Umbhobho we-HDPE unomgangatho ongaphakathi ogudileyo, kwaye i-coefficient yayo ye-Manning yi-0.009. Ukusebenza okugudileyo kunye{1}}neempawu zokuncamathela ziqinisekisa ukuba umbhobho weHDPE unomthamo ophezulu wokuhambisa kunemibhobho yesiqhelo, kodwa ukwanciphisa ilahleko yoxinzelelo kunye nokusetyenziswa kwamandla okuhambisa amanzi.
⑼ Ukuphathwa okulula: Umbhobho we-HDPE ulula kunombhobho wekhonkrithi, umbhobho we-galvanized kunye nombhobho wensimbi, kulula ukuthwala kunye nokufaka, amandla aphantsi kunye neemfuno zezixhobo, oku kuthetha ukuba iindleko zokufakela iprojekthi ziyancipha kakhulu.
⑽ Iindlela ezahlukeneyo zokwakha: Umbhobho we-HDPE unetekhnoloji eyahlukahlukeneyo yokwakha, ukongeza ekusebenziseni indlela yemveli yokwakha, unokusebenzisa ubuchwephesha obutsha obungenamingxuma obufana nokugqobhoza kombhobho, ukomba umbhobho, ulwakhiwo, ulwakhiwo lwetyhubhu yokuqhekeka, oku kwabanye akuvumeli ukugrunjwa, lolona khetho, ngoko ke isicelo sombhobho weHDPE sibanzi.
1, ukuthamba: kuba iPE-RT ithambile. Ngoko ke, akukho zixhobo zikhethekileyo ezifunekayo ngexesha lokwakha, ngoko ke iindleko zokwakha ziphantsi kakhulu{3}}, ukuqhutyelwa kwe-thermal: umbhobho osetyenziselwa ukufudumeza umgangatho kufuneka ube ne-conductivity efanelekileyo ye-thermal. I-PE- i-RT ine-conductivity elungileyo ye-thermal, kwaye i-thermal conductivity yayo iphindwe kabini kwi-PP- ye-R kunye ne-PP- yemibhobho ye-B. Ilungele ukufudumeza umgangatho.3. Ukumelana nobushushu obuphezulu: PE-RT inokumelana nobushushu obuphezulu ukuya kuma-90 degree, ngelixa i-PEX inokufikelela kuphela kuma-65℃.4,{14}}iqondo eliphantsi ukumelana nobushushu kunye nefuthe lokuxhathisa: PE- -RT low{16}}impembelelo yokumelana nobushushu ilungile. Ekwakhiweni kwasebusika, umbhobho akulula ukuba uchaphazeleke kwaye uphulwe, okwandisa ukuguquguquka kwelungiselelo lokwakha.5, ukukhuselwa kwendalo: PE -} RT kunye ne-PP- R inokuphinda isetyenziswe, ngaphandle kokungcolisa indalo. Kwaye i-PEX ayinakuphinda isetyenziswe
Iifayile ezishisayo: umbhobho weplastiki wepe umgca, eTshayina pe umgca mnye abavelisi bemibhobho yeplastiki, ababoneleli, umzi-mveliso
