Umenzi wemibhobho yentsimbi enganyangekiyo
Ipayipi yensimbi ye-Anticorrosive ibhekisela kumbhobho wensimbi ocutshungulwa yinkqubo ye-anticorrosive, enokuthi ithintele ngokufanelekileyo okanye icothise isiganeko esibangelwa yikhemikhali okanye i-electrochemical reaction ngexesha lokuthutha kunye nokusetyenziswa. Ngokutsho kwedatha yezibalo zaseChina, ilahleko yezoqoqosho ngokuthe ngqo kwi-corrosion yentsimbi yombhobho e-China ingaphezulu kwe-280 yezigidigidi minyaka yonke.
Okwangoku, ilahleko yonyaka yehlabathi jikelele ngenxa yokubola kwemibhobho yentsimbi iphezulu ukuya kuma-500 eebhiliyoni zeedola zaseMelika. Umbhobho wensimbi we-Anticorrosive unokuthintela ngokufanelekileyo okanye unciphise ukubola, ukwandisa ubomi benkonzo yombhobho wensimbi kunye nokunciphisa iindleko zokusebenza kombhobho wensimbi.
Ukuqamba
Yenziwe nge-aliphatic polyurethane prepolymer, i-epoxy resin, i-pigments ekumgangatho ophezulu, izongezo kunye nezinyibilikisi. Isetyenziselwa ngokukodwa ukulwa nokubola kwezixhobo ezidibana nokutya kunye namanzi okusela, ukuhanjiswa kwamanzi kunye nombhobho wokuhambisa kunye nomphezulu wetanki yamanzi okusela.
Ukusebenza
Ipeyinti i-polymer ye-technical interpenetrating network, eqalisa i-polymerization kwiqondo lokushisa. Amanethiwekhi amabini anokufunda omnye komnye kwaye avelise umphumo wentsebenziswano. Ifilimu ayinayo ityhefu, i-high solid and low viscosity. Yinto entsha yokugquma i-anti-corrosion ene-adhesion eqinile, amandla aphezulu, ukuxhathisa impembelelo, ukuxhathisa i-hydrolysis, ukuxhathisa ukubola, ukuxhathisa kwamanzi kunye nokumelana nemozulu, kwaye ineemfuno eziphantsi zokususwa komhlwa phezu kwesakhiwo sentsimbi, Ubushushu benkonzo bunokuba kuluhlu lwe - 20 ~ 120 ℃.
Iimpawu zobugcisa
1. Ixesha lokumisa: ukomiswa komphezulu we-30min kunye nokumisa okuqinileyo kwi-6-24h
2. Ukuguquguquka: 1mm
3. Ukuchasana kwempembelelo: 50cm
4. Ukuncamathela: iBanga loku-1
4. Ukwakhiwa kunye nokugcinwa
(1)Ngaphambi kokupenda, ubuso bentsimbi yesiseko buya kunyangwa kwi-Sa2.5. Akuvumelekanga ngokungqongqo ukuzisa amanzi, uthuli kunye neoli ngexesha lokwakha ukuqinisekisa umgangatho wokupeyinta.
(2) Umlinganiselo wokugquma: Icandelo A (isiseko sezinto), icandelo B (i-arhente yokunyanga) = 9kg ipeyinti: 1kg i-ejenti yokunyanga (okanye ukwakhiwa ngokomlinganiselo ochazwe ngumzi-mveliso wethu).
(3)Indlela yokulinganisa ukwakhiwa ngolu hlobo lulandelayo: vula ukuvulwa okukhulu kwecandelo A, yongeza icandelo B kwi-A, kwaye udibanise ngokupheleleyo. Emva kokunyanga imizuzu engama-30, ukugquma kungaqhutywa.
(4)Esi sixhobo sifunekayo ukuba silungiswe kwaye sisetyenziswe nangaliphi na ixesha, kwaye isambatho esilinganisiweyo kufuneka sisetyenziswe kwiiyure ezintandathu. Izinto ezingagqitywanga ziyakutywinwa kwaye zigcinwe.
(5)Ulwakhiwo luya kunqunyanyiswa ngeentsuku zemvula okanye xa ukufuma kungaphezulu kwama-75%. Kwiindawo ezinobunzulu be-corrosive medium, kuyacetyiswa ukuba usebenzise iidyasi ezininzi zepeyinti.
(6) Imveliso iya kugcinwa kwindawo epholileyo neyomileyo ukuthintela ukukhanya kwelanga, ukwahlula umthombo womlilo kwaye ugcine kude nomthombo wobushushu.
(7)Ixesha lokugcina ziinyanga ezili-12. Emva kokuphelelwa yisikhathi, izalathisi ezahlukeneyo zobugcisa ziya kuhlolwa. Ukuba ziyahlangabezana neemfuno zesalathiso, zinokuqhubeka zisetyenziswa.
I-Fusion bonded epoxy powder, eyaziwa ngokuba yi-thermosetting epoxy resin enzima-umsebenzi ochasene ne-corrosion powder, yinto eqinileyo ehanjiswayo kwaye isasazwe ngomoya njengomthwali. Isetyenziswe kumphezulu weemveliso zetsimbi ezifudumalayo, zinyibilike, ziqiniswe kwaye ziqiniswe ukuze zenze isambatho esifanayo. I-Anti-corrosion yi-heavy-duty anti-corrosion coating eyenziwe kubushushu obuphezulu. I-coating ineenzuzo zemisebenzi elula yokugquma, akukho ngcoliseko, impembelelo entle kunye nokumelana nokugoba kunye nokumelana nobushushu obuphezulu.
1)Ngokwendlela yesicelo, inokohlulwa ibe: ngumgubo wokutshiza ngaphakathi kumbhobho, umgubo wokutshiza ngaphandle kombhobho kunye nomgubo jikelele ngaphakathi nangaphandle kombhobho. Umgubo osetyenziselwa ukutshiza ngaphandle kombhobho wohlulwe ube ngumgubo womaleko omnye, umgubo ophindwe kabini kunye nomgubo ochasene nomhlwa.
2) Ngokwenjongo, inokohlulwa ibe: ngumgubo wombhobho we-oyile nerhasi, umgubo wombhobho wamanzi okusela, umgubo wombhobho womlilo, umgubo wombhobho wokungena umoya ochasene nestatic kumgodi wamalahle, umgubo wombhobho wemichiza, umgubo wombhobho wokomba wepetroleum. , umgubo wofakelo lwemibhobho, umgubo wombhobho wenqanawa, umgubo wamanzi anetyuwa eninzi-umsebenzi onzima wokuchasana nomhlwa, njl.
3)Ngokweemeko zokunyanga, inokwahlulwa ibe ziindidi ezimbini: ukunyanga ngokukhawuleza kunye nokunyanga okuqhelekileyo. Imeko yokuphilisa yomgubo wokuphilisa ngokukhawuleza ngokubanzi ngama-230 ℃ / 0.5 ~ 2min. Ikakhulu isetyenziselwa ukutshiza ngaphandle kombhobho okanye isaleko esine-anti-corrosion structure. Ngenxa yexesha elifutshane lokunyanga kunye nokusebenza kakuhle kwemveliso, ifanelekile ekusebenzeni komgca wendibano; Imeko yokuphilisa yomgubo onyangayo oqhelekileyo ungaphezulu kwe-230 ℃ / 5min. Ngenxa yexesha elide lokunyanga kunye nomgangatho olungileyo wokugubungela, kukulungele ukutshiza kwipayipi.
Ikakhulu zibandakanya: indlela yokutshiza ye-electrostatic, indlela yokutshiza nge-thermal, indlela yokufunxa, indlela yokulala i-fluidized, indlela yokugubungela umqulu, njl. Ezi ndlela zokutshiza zinento eqhelekileyo, oko kukuthi, ngaphambi kokutshiza, i-workpiece kufuneka ifudunyezwe kwiqondo lokushisa elithile ukuze inyibilike i powder ngokukhawuleza xa idibanisa. Ubushushu benkunkuma kufuneka buvumele ukuba ifilimu iqhubeke nokuhamba kwaye iqhubele phambili kwinqanaba kwaye igubungele yonke indawo yombhobho wentsimbi, ngakumbi ekudakaleni komphezulu wombhobho wentsimbi kunye namacala omabini e-weld, kunye nepeyinti etyhidiweyo igeleza ekuzaliseni ukwenza i-coating. ngokusondeleyo kunye nombhobho wensimbi, Nciphisa ama-pores kunye nokunyanga ngaphakathi kwexesha elichaziweyo. Ekugqibeleni, pholisa ngamanzi ukuphelisa inkqubo yokunyanga.
