Iimpawu zomzimba ezigqwesileyo.Ukusebenza kwe-polyethylene yoxinano oluphakathi kuphakathi kwe-polyethylene ephezulu kunye nephantsi.Ayigcini nje ngokugcina ukuqina kunye namandla e-polyethylene yoxinaniso oluphezulu, kodwa ikwanazo nokuguquguquka okuhle kunye nokuxhathisa kokurhubuluza, kwaye i-polyethylene yoxinaniso oluphezulu ishushu ngakumbi.Iimpawu zentsebenzo ebalaseleyo yokudityaniswa kwe-fusion ilungele ukufakwa kwemibhobho yeplastiki.
Ukumelana nokubola kunye nobomi benkonzo ende.Kwiindawo eziselunxwemeni lwelizwe lethu, umgangatho wamanzi aphantsi komhlaba uphezulu kwaye ukufuma komhlaba kuphezulu.Ukusetyenziswa kwemibhobho yensimbi engenamthungo kufuneka ibe yi-anti-corrosion kunye ne-external tempered for installer, kwaye ubomi benkonzo buyiminyaka engama-30 kuphela, ngelixa iipayipi ze-PE ziyakwazi ukumelana neentlobo ezahlukeneyo zeendaba zemichiza.i-corrosion, ngaphandle konyango oluchasayo.Kwakhona, ayikhuthazi ukukhula kwe-algal, ibhaktheriya okanye umngundo kwaye inobomi beminyaka engama-50.
Ukuqina okuhle kunye nokuguquguquka.Umbhobho we-PE luhlobo lombhobho wokuqina okuphezulu, ukunyuswa kwayo kwikhefu kudlula i-500%, inokulungelelaniswa okunamandla kwi-settlement engalinganiyo kunye nokuchithwa kwesiseko sombhobho, kwaye inokumelana ne-seismic.Kuqinisekisiwe ukuba umbhobho we-PE ngumbhobho onokuxhathisa ukothuka.Kukho intetho ethi kwinyikima yaseKobe eJapan ngo-1995, imibhobho ye-PE kunye nemibhobho yokuhambisa amanzi yayikuphela kwemibhobho engonakaliswanga.Ukongezelela, ukuguquguquka kombhobho we-PE kukuba umbhobho we-PE unokudityaniswa, ukunciphisa inani elikhulu lokudibanisa umbhobho wokudibanisa.Isalathiso sombhobho we-PE sinokutshintshwa ngokulula ngokweemfuno zendlela yokwakha.Ngexesha lokwakha, imiqobo inokugqithwa ngaphakathi kwendawo yokugoba evumelekileyo yombhobho ukunciphisa ubunzima bokwakha.
Umthamo wokujikeleza mkhulu kwaye uqoqosho luyonga iindleko.Udonga lwangaphakathi lombhobho we-PE luhamba kakuhle kwaye alulinganisi.Umlinganiselo olinganayo woburhabaxa bomgangatho wangaphakathi wombhobho we-PE yi-1/20 yalowo wombhobho wentsimbi.Umthamo wokuhamba kombhobho we-PE kunye nobubanzi bombhobho ofanayo, ubude obufanayo kunye noxinzelelo olufanayo malunga ne-30% enkulu kunombhobho wensimbi, ngoko ke inzuzo yezoqoqosho ibonakala.Xa kuthelekiswa nemibhobho yesinyithi, imibhobho ye-PE inokunciphisa utyalo-mali lweprojekthi malunga nesinye kwisithathu, kwaye imibhobho encinci ye-diameter enokuthi ihlanganiswe inokunciphisa ngakumbi iindleko zeprojekthi., Uxhulumaniso lufanelekile, ulwakhiwo lulula, kwaye iindlela ziyahluka.Umzimba wombhobho we-PE ulula, kulula ukuwuphatha, kulula ukuwudibanisa, kwaye unamalungu ambalwa okuwelda.Xa umbhobho omde, umbhobho wekhoyili unokusetyenziselwa ukubeka umbhobho we-PE.Iimfuno ziphantsi kakhulu kunomsele wombhobho wensimbi, kwaye xa iimeko zokwakha zilinganiselwe, i-electrofusion welding ingasetyenziswa.Ukongezelela, indlela yokuntywila umbhobho ingasetyenziselwa ukubeka phantsi kwamanzi, okunciphisa kakhulu ubunzima bokwakha kunye neendleko zobunjineli.
Ukutywinwa okulungileyo.Umbhobho we-PE ngokwawo udityaniswe kwaye udibaniswe, oqinisekisa ngokuqinisekileyo ubunikazi bezinto eziphathekayo, isakhiwo kunye nomzimba wombhobho ngokwawo, kwaye uqaphela ukudibanisa kunye nombhobho.Amandla okuqina kunye nokugqabhuka kwamandla e-interface angaphezulu kunezo zombhobho womzimba, onokuthi uxhathise ngokufanelekileyo uxinzelelo lwe-hoop kunye noxinzelelo lwe-axial oluveliswa luxinzelelo lwangaphakathi.Ke ngoko, xa kuthelekiswa nohlobo lwe-rubber yeringi yamalungu okanye amanye amalunga omatshini, akukho mngcipheko wokuvuza obangelwa kukugqwetheka okudibeneyo, kwaye ukusebenza kokutywinwa kuhle kakhulu.
Kulula ukuyigcina kwaye inokulungiswa kwaye ifakwe ngaphandle kwamanzi kunye negesi.
Ukumelana kakuhle nokuqhekeka koxinzelelo:Umbhobho we-PEinovelwano lwenotshi ephantsi, amandla aphezulu okucheba kunye nekhono lokuchasa ukukrwela, kunye nokumelana noxinzelelo olubalaseleyo lwendalo.Ukumelana okuhle kwefuthe lobushushu obuphantsi: Ubushushu obuphantsi be-embrittlement bobushushu bombhobho we-PE buphantsi kakhulu, kwaye bunokusetyenziswa ngokukhuselekileyo kuluhlu lobushushu lwe--60 degrees Celsius.Emantla elizwe lam, xa i-polyethylene engcwatyelwe ukunikezelwa kwamanzi ifakwe kwintsimi ebusika, kugqitywa ukuba ayifanelekanga ukubeka ukwakhiwa phantsi kweedigri zero, kuba umbhobho we-polyethylene ulula.Ukumelana kakuhle ne-abrasion.Uvavanyo lokuthelekisa ukunxitywa kombhobho we-polyethylene kunye nombhobho wensimbi ubonisa ukuba ukuxhathisa kwayo kumaxesha angama-4 kumbhobho wensimbi.
