Umkhiqizi wepayipi lensimbi elimelana nokugqwala
Ipayipi lensimbi elivimbela ukubola libhekisela epayipini lensimbi elicutshungulwe ngenqubo ye-anticorrosive, engavimbela ngempumelelo noma inciphise isenzakalo sokugqwala okubangelwa ukusabela kwamakhemikhali noma kwe-electrochemical ngesikhathi sokuthutha kanye nokusetshenziswa. Ngokusho kwedatha yezibalo zaseChina, ukulahleka kwezomnotho okuqondile kokugqwala kwamapayipi ensimbi eChina kungaphezu kwezigidigidi ezingama-280 minyaka yonke.
Njengamanje, ukulahlekelwa kwaminyaka yonke emhlabeni jikelele ngenxa yokugqwala kwamapayipi ensimbi kuphezulu ngendlela efinyelela kumabhiliyoni angama-500 wamadola aseMelika. Ipayipi lensimbi ye-Anticorrosive lingavimbela ngempumelelo noma linciphise ukugqwala, lelule impilo yesevisi yepayipi lensimbi futhi linciphise izindleko zokusebenza kwepayipi lensimbi.
Ukwakheka
Yakhiwe nge-aliphatic polyurethane prepolymer, i-epoxy resin, i-pigment yekhwalithi ephezulu, izithasiselo nezincibilikisi. Isetshenziselwa ngokukhethekile ukulwa nokugqwala kwezinto zokusebenza ezithinta ukudla namanzi okuphuza, ipayipi lokuhambisa amanzi kanye nokusabalalisa kanye nengaphezulu lethangi lamanzi okuphuza.
Ukusebenza
Upende uyi-polymer yenethiwekhi ye-technical interpenetrating, eqala i-polymerization ekamelweni lokushisa. Amanethiwekhi amabili angafunda komunye nomunye futhi akhiqize umphumela wokubambisana. Ifilimu ayinabo ubuthi, iqinile futhi ine-viscosity ephansi. Kuyi-anti-corrosion coating entsha enamathela ngokuqinile, amandla aphezulu, ukumelana nomthelela, ukumelana ne-hydrolysis, ukumelana nokugqwala, ukumelana namanzi kanye nokumelana nesimo sezulu, futhi inezidingo eziphansi zokususwa kokugqwala ebusweni besakhiwo sensimbi, izinga lokushisa lesevisi lingaba ebangeni - 20 ~ 120 ℃.
Izinkomba zobuchwepheshe
1. Isikhathi sokumisa: ukomiswa ngaphezulu kwemizuzu engama-30 nokomisa okuqinile amahora angama-6-24
2. Ukuvumelana nezimo: 1mm
3. Ukumelana komthelela: 50cm
4. Ukunamathela: Ibanga 1
4. Ukwakhiwa nokugcinwa
(1)Ngaphambi kokudweba, ubuso bensimbi eyisisekelo buzophathwa ku-Sa2.5. Kuvinjelwe ngokuqinile ukuletha amanzi, uthuli namafutha ngesikhathi sokwakhiwa ukuze kuqinisekiswe ikhwalithi yokudweba.
(2) Ingxenye yokwemboza yile: ingxenye A (isisekelo sezinto), ingxenye B (i-ejenti elaphayo) = 9kg upende: 1kg i-ejenti yokwelapha (noma ukwakhiwa ngokwengxenye eyaziswa ifekthri yethu).
(3)Indlela yokulinganisa yokwakha imi kanje: vula ukuvuleka okukhulu kwengxenye A, engeza ingxenye B engxenyeni A, futhi uhlanganise ngokugcwele ngokulinganayo. Ngemuva kokupholisa imizuzu engama-30, ukumbozwa kungenziwa.
(4)Lokhu kwaziswa kuyadingeka ukuba kulungiswe futhi kusetshenziswe nganoma isiphi isikhathi, futhi ukunamathela okulinganiselwe kufanele kusetshenziswe kungakapheli amahora ayisithupha. Izinto ezingaqediwe zizovalwa futhi zigcinwe.
(5)Ukwakhiwa kuzomiswa ngezinsuku zemvula noma lapho umswakama ohlobene ungaphezu kuka-75%. Ezingxenyeni ezine-corrosive medium enamandla, kunconywa ukusebenzisa amajazi amaningi kapende.
(6) Umkhiqizo kufanele ugcinwe endaweni epholile futhi eyomile ukuvimbela ukukhanya kwelanga okuqondile, ukuhlukanisa umthombo womlilo kanye nokugwema umthombo wokushisa.
(7)Isikhathi sokugcina yizinyanga eziyi-12. Ngemva kokuphelelwa yisikhathi, izinkomba ezihlukahlukene zobuchwepheshe zizohlolwa. Uma zihlangabezana nezidingo zenkomba, zingaqhubeka zisetshenziswa.
I-Fusion bonded epoxy powder, eyaziwa nangokuthi i-thermosetting epoxy resin heavy-duty anti-corrosion powder, iyimpahla eqinile ethuthwayo futhi ihlakazwe ngomoya njengesithwali. Isetshenziswa ebusweni bemikhiqizo yensimbi esandulelwe ngaphambili, encibilikisiwe, ilinganiswe futhi iqiniswe ukuze yenze i-coating efanayo. I-Anti corrosion iyi-heavy-duty anti-corrosion coating eyakhiwe ezingeni lokushisa eliphezulu. I-coating inezinzuzo zokusebenza okulula kokugqoka, akukho ukungcola, umthelela omuhle nokumelana nokugoba kanye nokumelana nokushisa okuphezulu.
1)Ngokwendlela yokufaka isicelo, ingahlukaniswa ibe: impushana yokufafaza ngaphakathi kwepayipi, impushana yokufafaza ngaphandle kwepayipi kanye nempushana evamile ngaphakathi nangaphandle kwepayipi. Impushana esetshenziselwa ukufafaza ngaphandle kwepayipi ihlukaniswe yaba yimpushana yongqimba olulodwa, impushana yongqimba oluphindwe kabili kanye ne-anti-corrosion structure enezingqimba ezintathu.
2) Ngokwenhloso, ingahlukaniswa ibe: impushana yepayipi likawoyela negesi, impushana yepayipi lamanzi okuphuza, impushana yepayipi lomlilo, impushana yepayipi le-anti-static ventilation emayini yamalahle, impushana yamapayipi amakhemikhali, i-powder yepayipi lokubhoboza i-petroleum. , impushana yokufakwa kwamapayipi, impushana yepayipi lomkhumbi, impushana yamanzi anosawoti omningi wepayipi elivikela ukugqwala, njll.
3)Ngokwezimo zokuphulukisa, ingahlukaniswa ngezinhlobo ezimbili: ukwelapha ngokushesha kanye nokwelapha okuvamile. Isimo sokuphulukisa sempushana ephulukisa ngokushesha ngokuvamile singu-230 ℃ / 0.5 ~ 2min. Isetshenziselwa kakhulu ukufafaza ngaphandle kwepayipi noma isakhiwo sokulwa nokugqwala kwezingxenye ezintathu. Ngenxa yesikhathi esifushane sokuphulukisa nokusebenza kahle kokukhiqiza, kufanelekile ekusebenzeni komugqa womhlangano; Isimo sokuphulukisa sempushana yokuphulukisa evamile ngokuvamile singaphezu kuka-230 ℃ / 5min. Ngenxa yesikhathi eside sokuphulukisa kanye nokulinganisa okuhle kokumboza, kufanelekile ukufafaza epayipini.
Ikakhulukazi zihlanganisa: electrostatic sishaye indlela, ezishisayo sishaye indlela, ukumunca indlela, fluidized umbhede indlela, roll enamathela indlela, njll Friction electrostatic sishaye indlela, ukumunca indlela noma ezishisayo sifutho indlela ngokuvamile asetshenziselwa ipayipi enamathela yangaphakathi; Lezi zindlela zokufafaza zinesici esivamile, okungukuthi, ngaphambi kokufafaza, i-workpiece idinga ukushiswa ngaphambi kokushisa okuthile ukuze incibilike i-powder ngokushesha nje lapho ixhumana. Ukushisa kwemfucuza kufanele kuvumele ifilimu ukuthi iqhubeke nokugeleza kanye nezinga eliqhubekayo futhi imboze yonke indawo yepayipi lensimbi, ikakhulukazi ekucindezelekeni kwendawo yepayipi lensimbi nezinhlangothi zombili ze-weld, futhi upende oncibilikisiwe ugelezela ekugcwaliseni ukwenza okokunamathela. kuhlanganiswe eduze nepayipi lensimbi, Nciphisa ama-pores futhi welaphe phakathi nesikhathi esibekiwe. Ekugcineni, pholisa ngamanzi ukuze unqande inqubo yokwelapha.
