Injongo yezixhobo zokuzihlaziya
Ukuthintela umphezulu wangaphandle wemibhobho yentsimbi kubalulekile ukuthintela ukuphoxeka. Ukuphamba kumphezulu wemibhobho yentsimbi kunokukuchaphazela kakhulu ukusebenza kwabo, umgangatho kunye nokubonakala okubonakalayo. Yiyo loo nto inkqubo yokuthuka inefuthe elibonakalayo kumgangatho opheleleyo weemveliso zentsimbi zentsimbi.

Izinto ezifunekayo kwizixhobo zokuhamba
Ngokwemigangatho ebekiweyo yiZiko lePetroleum yasePetroleum, imibhobho yentsimbi kufuneka ixhathise ukuvela okungenani iinyanga ezintathu. Nangona kunjalo, imfuno yexesha elide lokulwa ne-rust inyuke, kunye nabasebenzisi abaninzi abafuna ukumelana neenyanga ezintathu ukuya kwezi-6 kwiimeko zogcino lwangaphandle. Ngaphandle kwemfuneko yobomi obungongangesiyo, abasebenzisi balindele ukuba kugcinwe umphezulu, nokuba nokusasazeka kweearhente ezichasene nokuchasana ne-skhorrosvers ngaphandle kwezikrip okanye iidrip ezinokuchaphazela umgangatho wokubonakalayo.

Iindidi zezinto zokuzihlaziya kunye nendlela yazo
Kwidolophu engaphantsi komhlaba,Imibhobho yentsimbiZiya kusetyenziselwa ukusetyenziselwa ukuthutha igesi, ioyile, amanzi, nangaphezulu. Iingubo zale mibhobho ziye zavela kwizinto ze-asphalt zemveli kwi-polyethylene resin kunye ne-epoxy resn. Ukusetyenziswa kwe-Polythylene Realthyneys yaqala ngo-1980s, kunye nezicelo ezahlukeneyo, amacandelo kunye neenkqubo zokuziqeqesha ziye zabona ukuphuculwa kancinci kancinci.
3.1 I-Petroleum Asphalt Cook
Petroleum asphalt coating, a traditional anti-corrosive layer, consists of petroleum asphalt layers, reinforced with fiberglass cloth and an external protective polyvinyl chloride film. Inika amanzi okungaphezulu, ukunamathela okulungileyo kwimiba ephezulu, kunye nokusebenza ngendleko. Nangona kunjalo, inezixhobo zokuzibamba kubandakanya ukutshitshiswa kubushushu beqondo lobushushu, ukuba ne-brittle kumaqondo obushushu aphantsi, kwaye ukuthambeka kukohliswa kunye nokuqhekeka, ngakumbi kwiindleko ezongezelelweyo zomhlaba kunye nokunyuka kweendleko.
3.2 I-Coal Tar Epoxy Coating
I-Coal tapoxy, eyenziwe kwi-Epoxy Realhin kunye ne-Asphal Tar Asphalt, ibonakalisa ukuxhathisa kwamanzi apheleleyo kunye nokuchasana nemichiza, ukunamathela koomatshini, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, amandla obuchwephesha, kunye noomatshini, kunye noomatshini bokulinganisa. Nangona kunjalo, ifuna ukuphiliso okwethutyana okudala, esenza ukuba ihlawulwe kwimiphumo emibi evela kwiimeko zemozulu ngeli xesha. Ngapha koko, iindawo ezahlukeneyo ezisetyenziswa kule nkqubo yokuthuka ifuna ukugcina okhethekileyo, ukuphakamisa iindleko.
3.3 I-Epoxy Powder
I-Epoxy Powder Coating, yaziswa nge-1960s, ibandakanya ukutshiza ngomgubo ophathwayo kumgangatho we-pube ngaphambi kwexesha, evuthayo. Izibonelelo zayo zibandakanya uluhlu lwamaqondo obushushu ngokubanzi (-60 ° ukuya kwi-100 ° C), ukunamathela okuqinileyo, ukunganyangeki okuhle kwi-Cathodic, ifuthe, ukuguquguquka, ukuguquguquka, kunye nomonakalo we-weld. Nangona kunjalo, ifilimu yayo yomthimbi iyenza ukuba ibethelelekile kumonakalo kwaye ifuna iindlela zemveliso ezinobunkunkqele kunye nezixhobo, zokucela imiceli mngeni kwisicelo secandelo. Ngelixa igqwesa kwiinkalo ezininzi, iwela kufutshane ngokuthelekiswa ne-polyethylene ngokuchasene nobushushu kunye nokukhusela ngokupheleleyo.
3.4 I-Poalyethylene anti-cocaight
I-Polythylene inika ukunganyangeki kwempembelelo entle kunye nobunzima obuphezulu kunye noluhlu lobushushu obubanzi. Ifumana ukusetyenziswa kakhulu kwimimandla ebandayo efana neRussia naseNtshona Yurophu ngemibhobho ngenxa yokuguquguquka kwayo ebalaseleyo kunye nokungavisisani kwempembelelo, ngakumbi kumaqondo obushushu asezantsi. Nangona kunjalo, imiceli mngeni ihleli kwisicelo sayo kwimibhobho emikhulu yedayameter, apho uxinzelelo lungavela, kwaye i-ingeress yamanzi inokukhokelela phantsi kwengqungquthela phantsi kolawulo, inyanzelisa ngeendlela zokufunda kunye nezicelo.
I-3.5 i-anti-corrosion yosulelo
I-corasings eninzi yokunyanzelwa iyonke ibonelela ngokuchasene nokunganyangeki okuphuculweyo okuthelekiswayo xa kuthelekiswa nemveliso esemgangathweni. Babonisa ukusebenza kwexesha elide nakwimeko ezinzima, kunye nobomi obuninzi beminyaka eli-10 ukuya kweli-15 kwiMikhamikhali, eManzini, kunye neMigangatho emi-5 kwi-Acidic, ialkaline, okanye iimeko ze-acidine, okanye iimeko ze-acidine, okanye iicawa. Ezi ziqwengana ziqhelekileyo zinobukhulu owomileyo kwifilimu ukusuka nge-200μm ukuya kwi-2000μm, ukuqinisekisa ukhuseleko oluphezulu kunye nokuqina. Basetyenziswa ngokubanzi kwizakhiwo zaselwandle, izixhobo zekhemikhali, iitanki zokugcina, kunye nemibhobho.

Uhlalutyo lwemicimbi esemgangathweni
Yonke ingxaki ivela kwizizathu ezahlukeneyo, kubangelwa zizinto ezahlukeneyo; Kwaye iqhekeza lombhobho wentsimbi eboniswe ngumgangatho wengxaki isenokuba yindibaniselwano yeqela. Unobangela wokudibana okungalinganiyo kunokubahlulahlula iintlobo ezimbini, enye yinto engalinganiyo ebangelwe kukutshiza emva kombhobho wentsimbi ungena kwibhokisi yokucoca; Okwesibini yinto engalinganiyo ebangelwa kukungatshizi.
Isizathu sento yokuqala ngokucacileyo silula ukuyibona, kwizixhobo ezinamathi Ukuba umpu ngamnye uphethwe kubungakanani bokuhamba uye wahlukile, kuya kukhokelela ekusasazeni okungalinganiyo kwearhente ye-anticorrossive kwimiba emininzi yombhobho wentsimbi.
Isizathu sesibini kukuba zikho ezinye izizathu zento engalinganiyo yokungalingani ngaphandle kwento yokutshiza. Zininzi iintlobo zezinto, ezinje ngombhobho wentsimbi engenalo, ukrokrela, ukuze ukuqabha kuya kunzima ukusasazwa ngokunzulu; Umphezulu we-puwe wentsimbi unemilinganiselo yokusebenza yamanzi eshiyekileyo xa i-emulsion, ngeli xesha kukudibana nombhobho wentsimbi, ukuze kungabikho mkhwa wokuhamba kwentsimbi, okoko kunzima ukuba i-pipe yentsimbi ayifani.
. Icandelo lomphunga lombhobho wentsimbi ijikeleze, ngalo lonke ixesha iarhente ye-antikoorrosve itshizwe kumphezulu wombhobho wentsimbi, iarhente ye-anticorrossive kwinxalenye esezantsi kwaye iyoyisela le meko yehla. Into elungileyo kukuba kukho iindlela ze-oveni kumgca wokudibana womhadi womzi-mveliso wentsimbi, onokufudumeza aze aqinise iarhente yentsimbi ngexesha iarhente yentsimbi. Nangona kunjalo, ukuba i-vikosity ye-arhente yokulwa i-anticorrosive ayiphezulu; hayi ukufudumeza ngexesha emva kokutshiza; okanye amaqondo obushushu ashushu akaphakami; I-nozzle ayikho kwimeko elungileyo yokusebenza, njl. njl.
(2) Izizathu zokuchasana nokuchasa. Ngenxa yemeko yendawo yokusebenza ye-themidy yomoya, ukusasazeka kwepeyinti igqithisileyo, ukusasazeka kweqondo lokusasaza lenkqubo kuya kubangela i-bubblenop yokugcina i-bubblen. Imeko yobume bomoya, iimeko zobushushu ezisezantsi, i-prevvatites ikhutshelwe ngaphandle kwee-tidples ezincinci, ziya kukhokelela kwihlazo lobushushu. Amanzi emoyeni anomanyano oluphezulu emva kokuba iqondo lobushushu liya kuza kulithanda ukwenza amanzi amdaka axubeneyo, kwaye ekugqibeleni ungene kwi-coraist, ekhokelela kwi-biomeno yokukhokelela.
