Umbhobho waseTshayina wokufaka umbhobho wentsimbi umenzi
1. 3PE ukhuseleko lomhlwa
Uluhlu oluthathu lwe-PE anti-corrosion structure of the pipeline: umaleko wokuqala we-epoxy powder (FBE> 100um), umgca wesibini we-adhesive (AD) 170 ~ 250um, kunye nomgangatho wesithathu we-polyethylene (PE) 2.5 ~ 3.7mm. Izinto ezithathu zihlanganiswe kwaye zidibaniswe ngokuqinileyo kunye nombhobho wensimbi ukuze zenze i-coat anti-corrosion egqwesileyo.
Uluhlu lwedayamitha yombhobho Φ 60～ Φ iwaka elinamakhulu amane anamashumi amabini
2. Umbhobho wensimbi we-2PE we-anticorrosive
Imigangatho emibini ye-PE anticorrosive structure for pipeline, umaleko wokuqala we-adhesive (AD) kunye nowesibini we-polyethylene (PE), izinto ezimbini zidibeneyo, kwaye ubukhulu boluhlu ngalunye bufana nolwesithathu lwe-PE.
Umgangatho: SY / t0413-2002 umgangatho wobugcisa we-polyethylene anticorrosive coating yombhobho wentsimbi ongcwatywe
I-GB / t23257-2009 umgangatho wobugcisa we-polyethylene anticorrosive coating yombhobho wentsimbi ongcwatywe
3. Umbhobho wentsimbi ye-PE oyenye ye-anticorrosive
Ukuthelekisa phakathi kwe-polyethylene yomgca omnye kunye ne-polyethylene enemigangatho emithathu
Ukuthelekisa phakathi kwe-polyethylene yomgca omnye kunye ne-polyethylene enemigangatho emithathu
Umbhobho wentsimbi we-PE we-anti-corrosive one-single wamkela inkqubo yokugquma isitshizi (ekwabizwa ngokuba yindlela yomkhusane) ukujikelezisa umbhobho wentsimbi ofudunyezwe ngamaza aphakathi. Uluhlu oluphezulu lombhobho wensimbi yisitya esine-polyethylene powder, efafazwe phezu kodonga lwangaphandle lombhobho wensimbi ukwenza i-polyethylene yokugqoka. Umgangatho olawulayo CJ / t120-2008 umbhobho wentsimbi odityanisiweyo weplastiki odityanisiweyo wonikezelo lwamanzi.
1. Ukuqulunqwa
Imveliso ilungiswe ukusuka kwi-epoxy resin, i-coal tar pitch, i-antirust pigment, izongezo kunye ne-amine elungisiweyo. Imveliso ineenzuzo zokumisa ngokukhawuleza, ukubambelela kakuhle, ukuguquguquka okulungileyo, ukupakishwa kwamacandelo amabini kunye nokwakhiwa okulula. Ineempawu ze-asidi, i-alkali, ityuwa, amanzi kunye nokumelana neoli.
2. Iimpawu kunye nokusetyenziswa
Ipeyinti idibanisa iimpawu zamandla aphezulu omatshini, amandla amakhulu okunamathela, ukuxhatshazwa kweekhemikhali okuphakathi kwe-epoxy resin kunye nokumelana namanzi, ukuxhathisa i-microbial kunye nokuxhathisa ingcambu ye-asphalt. Yeyona ndlela iphezulu yokuvala umhlwa yokugquma. Imveliso inokumelana neekhemikhali ezilungileyo kunye nokuchasana kwamanzi.
Isebenza kwi-anti-corrosion ye-oyile, igesi kunye nemibhobho yamanzi, amanzi epompo, igesi, imibhobho, iindawo zokucoca i-oyile, izityalo zemichiza kunye neendawo zokucocwa kogutyulo. Isenokusetyenziswa njengento yokunqanda ukubola kwamaqonga okomba ioli kude nonxweme kunye neendawo ezingaphantsi kwamanzi ezinqanaweni, kunye nokuthintela ukubola kwemigodi kunye nezixhobo eziphantsi komhlaba.
Ijacket ye-polyethylene ephezulu ye-anti-corrosion structure: umbhobho wensimbi uhlanganiswe nge-high-density polyethylene material, enamandla amakhulu omatshini kunye nokumelana nokugqwesa okugqwesileyo, kwaye inokukhusela umbhobho wensimbi kumonakalo obangelwa yimiba yangaphandle ngexesha lokuthutha, ukufakwa kunye nokusetyenziswa. I-Antioxidant, i-ultraviolet stabilizer, i-carbon black, njl.njl. iya kongezwa ekwenzeni umkhono wangaphandle. Umkhono wangaphandle we-polyethylene kulula ukuguga. Ukuba igcinwe kwindawo evulekileyo, kufuneka igqunywe nge-tarpaulin kunye nezinye izinto. Indawo yokupakisha kufuneka ibe kude nobushushu obuphezulu kunye nomthombo womlilo. Emva kokuba umbhobho wetsimbi we-anti-corrosion wenziwe, akuvumelekanga ukuba ubekwe elangeni kwaye ucinywe, ngaphandle koko umkhono wangaphandle we-polyethylene ulula ukuqhekeka kunye nokuchaphazela ukusebenza kwemveliso kunye nobomi benkonzo.
I-epoxy powder iye yaqatywa yinkqubo yokutshiza nge-electrostatic. Ngenxa yengxaki yokubambelela kwenkqubo ye-epoxy powder impregnation, ukufakelwa kwe-epoxy powder akuzange kubonwe. Okwangoku, ngophuhliso oluyimpumelelo lwesisombululo esikhethekileyo se-phosphating ye-epoxy powder impregnation ye-Sanye, ingxaki yokubambelela kwenkqubo ye-epoxy powder impregnation iye yanqotshwa okokuqala, kwaye inkqubo ephumayo ye-epoxy powder impregnation iqalile ukubonakala.
Izinto ezisisiseko zemibhobho yentsimbi echasene nomhlwa zibandakanya imibhobho ejikelezayo, imibhobho yomthungo ethe tye, imibhobho engenamthungo, njl.njl e-China, zisetyenziswa ngokubanzi kwiinkalo zobunjineli bemibhobho efana nokuhanjiswa kwamanzi omde, i-petroleum, ishishini lemichiza, igesi yendalo, ubushushu. , ukucocwa kwamanzi amdaka, umthombo wamanzi, ibhulorho, isakhiwo sentsimbi, ukuhanjiswa kwamanzi olwandle kunye nokufaka inqwaba.
