Umzi-mveliso wombhobho wentsimbi onganyangekiyo
Izinto ezisisiseko zombhobho wensimbi we-3PE we-anticorrosive ibandakanya umbhobho wensimbi ongenamthungo, umbhobho wentsimbi ojikelezayo kunye nombhobho wentsimbi othe ngqo. Umaleko wesithathu wepolyethylene (3PE) yokugquma isigqubuthele isetyenziswe ngokubanzi kushishino lwemibhobho yepetroleum ngenxa yokuxhathisa kwayo kakuhle ekumdleni, amanzi kunye nerhasi enokugqobhoza kunye neempawu zoomatshini. I-anti-corrosion coating ye-3PE anti-corrosion steel pipe ibaluleke kakhulu kwinkonzo yobomi bemibhobho engcwatywe. Eminye imibhobho yesixhobo esifanayo ingcwatywa ngaphantsi komhlaba amashumi eminyaka ngaphandle kokubola, kwaye eminye ivuza kwiminyaka embalwa. Ngenxa yokuba basebenzisa iingubo zangaphandle ezichasene ne-corrosion.
Umbhobho wensimbi we-3PE we-anticorrosive ubhekiselele kumbhobho wentsimbi wangaphandle ochasene ne-anticorrosive kunye ne-3-layer structural polyethylene coating (mapec), esetyenziswa ngokuqhelekileyo umbhobho wokunqanda ukubola e-China. Ezinye iindlela zokulwa nokubola ziquka ipn8710, i-FBE epoxy powder, i-epoxy coal tar pitch njalo njalo. Ngokuqhelekileyo ibhekisela kwi-anti-corrosion yodonga lwangaphandle lombhobho wensimbi. Ifomu ye-Anti corrosion yombhobho wentsimbi udonga lwangaphandle.
Umaleko wokuqala womgubo we-epoxy (FBE> 100um)
Uluhlu lwesibini lwe-adhesive (AD) yi-170 ~ 250um
Uluhlu lwesithathu lwe-polyethylene (PE) yi-1.8 ~ 3.7mm
Ngokuziqhelanisa, izinto ezintathu zixutywe kwaye zidibaniswe kwenye, ezidityaniswe ngokuqinileyo kunye nombhobho wensimbi emva kokucubungula ukwenza i-coat anti-corrosion. iindlela zayo processing zahlulwe ngokubanzi uhlobo ukujija kunye nesetyhula kufa uhlobo ukutyabeka.
I-3PE yokugquma umbhobho wentsimbi yokugquma (i-polyethylene ye-anticorrosive ye-anticorrosive coating) ngumbhobho omtsha we-anticorrosive wentsimbi eveliswa ngobuchule bokudibanisa i-2PE yokugquma kwe-anticorrosive eYurophu kunye ne-epoxy powder anticorrosive steel pipe caating (FBE) esetyenziswa ngokubanzi eMntla Melika. Sele iqatshelwe kwaye isetyenziswa kwihlabathi liphela iminyaka engaphezu kweshumi.
Umbhobho wensimbi we-3PE we-anti-corrosion yi-epoxy powder anti-corrosion coating edibene nomphezulu wepayipi yensimbi, kunye nomgangatho ophakathi yi-adhesive ye-copolymer kunye neqela elisebenzayo lesakhiwo sesebe. Umaleko ongaphezulu yi-high-density polyethylene anti-corrosion coating.
I-PE ye-anticorrosive coating emithathu idibanisa ukunganyanzeki okuphezulu kunye neempawu eziphezulu zemishini ye-epoxy resin kunye ne-polyethylene. Ukuza kuthi ga ngoku, yamkelwa njengowona mbhobho ogqwesileyo wokulwa nomhlwa onesiphumo esihle kunye nokusebenza kwihlabathi, esetyenziswe kwiiprojekthi ezininzi.
Umgangatho we-SY / t0413-2002 uphunyezwe e-China kwaye uphunyezwe ukususela ngo-Agasti 1, 2002. Umgangatho uchaza ngokukodwa i-polyethylene kunye ne-high-density polyethylene, kunye ne-Vicat softening point ayikho ngaphantsi kwe-110 ℃; Ubuninzi be-anti-corrosion coating yangaphandle buya kumiselwa ngokwemigangatho yaseJamani i-din30670-1991 elawulwa yi-polyethylene ephantsi kunye nephakathi. Amandla empembelelo ye-3PE ye-anticorrosive coating iphuculwe kakhulu. I-SY / t0413-2002 iphucula kakhulu amandla e-peel kunye nokuchasana kwempembelelo ye-3PE anti-corrosion coating, ichaza ngokucacileyo ukuba ngokomxholo wekhabhoni omnyama wezinto ezithile ezikhethekileyo, amandla omatshini kunye nokumelana nemozulu ye-3PE anti-corrosion coating iqinisekisiwe, kwaye iisampulu yamatyeli aphindaphindwayo yokomelela kwexolo elidityanisiweyo (okt ukomelela kwexolo lomkhono oshwabeneyo wobushushu kunye nebhanti elishwabeneyo lobushushu kwintsimbi yokuqala) liyenyuka.
Ngenjongo ye-3PE anti-corrosion steel pipe, abantu abaninzi bayazi into enye kwaye abayazi enye. Umsebenzi wayo ngokwenene ugubungela uluhlu olubanzi. Ilungele unikezelo lwamanzi angaphantsi komhlaba kunye ne-drainage, i-shotcrete ephantsi komhlaba, i-positive kunye ne-negative yokungena komoya, i-gas drainage, isitshizi somlilo kunye nolunye uthungelwano lwemibhobho kwimigodi yamalahle. Amanzi okucoca, intsalela yenkunkuma kunye nokubuyisela umbhobho wothumelo lwamanzi kwiziko lamandla obushushu. Isebenza ngokugqwesileyo kumbhobho wonikezelo lwamanzi we-anti spray kunye nenkqubo yokutshiza. Imikhono ekhuselayo yekhebula yamandla, unxibelelwano, indlela yokukhawuleza, njl njl. Ilungele ukuhanjiswa kwamanzi kwizakhiwo eziphakamileyo, unikezelo lobushushu lothungelwano lokufudumeza, ubunjineli bamanzi ompompo, ukuhanjiswa kwegesi, ukuhanjiswa kwamanzi angcwatywe kunye neminye imibhobho. Umbhobho wothumelo lwe-oyile, umbhobho wenkqubo yokuthutha imidiya edlekayo kumashishini ekhemikhali, amayeza, oshicilelo kunye nawokudaya. Imisebenzi yokuthintela umhlwa yombhobho wokulahlwa kwamanzi amdaka, umbhobho wogutyulo kunye netanki yebhayoloji. Kunokuthiwa umbhobho wensimbi we-3PE we-anti-corrosion uyimfuneko kulwakhiwo lwangoku, kwaye kukholelwa ukuba ngokwandiswa kwesayensi kunye nobuchwepheshe, kuya kuba nempumelelo eqaqambileyo kwixesha elizayo.
