Huayang Steel yeeb nkab, ib daim duab muaj npe hauv cov raj tshuaj tiv thaiv kev lag luam, tau teem tseg corrosion rhiav, teem sijhawm los pib ua haujlwm hauv lub Rau Hli. Lub xeev no - ntawm {4 4}}}}}}}}} corrosion daws teeb meem.
1. Yeeb nkab inlet: kev thauj mus los rau cov kab ntau lawm
Cov txheej txheem ncaws tawm nrog cov yeeb nkab inlet theem. Ntawm no, ib qho tshiab "Tumbler" mechanism tau ua haujlwm rau thauj cov kav hlau hlau mus rau qhov kawg ntawm lub platform. Tom qab, cov xaim transporter khov kho hloov cov kav dej los ntawm tumbler khib mus rau txhaj tshuaj blasting kab. Qhov kev ua haujlwm tsis sib xws no tau txav mus los ntawm cov kav hlau steel los ntawm sab nraum zoov cov yeeb nkab khib mus rau lub ntsej muag blasting kab, teeb tsa theem rau cov txheej txheem tom ntej.
2. Nto Preheating: kom ntseeg tau qhov kev mob siab rau xeb tshem tawm
Txhawm rau txhim kho qhov ua tau zoo ntawm kev txhaj tshuaj tiv thaiv blasting thiab tshem tawm cov npoo av saum npoo av, cov kav hlau steel, cov kav hlau txuas mus sab nrauv. Qhov no yog tiav los ntawm nruab nrab - cua sov} cua sov, uas nce qhov ntsuas kub ntawm cov kav dej. Los ntawm kev ua yog li ntawd, tsis yog tsuas yog noo noo tshem tawm, tab sis kev txhaj tshuaj tiv thaiv kab mob ib zaug rau cov kab mob uas zoo tshaj plaws rau cov tsho tiv no tom ntej.
3. Sab nraud phab ntsa tua blasting rau xeb tshem tawm: Precision thiab Kev Ntsuas Zoo
Ob lub tshuab txhaj tshuaj blasting tau teem rau hauv series los ua cov txheej txheem phab ntsa sab nraud blasting blasting cov txheej txheem. Kauj Ruam Cov kauj ruam no ua kom muaj xeb ntau dua los ua kom tiav qib GB / T 8923, thiab tsim kom muaj kev sib cav sib ceg nrog lub qhov tob tob ntawm {μm. Qhov no rhewsness tseem nce qhov chaw tiv tauj nrog FBE txheej, txhawb kev ua kom zoo dua. Kev tawm koob txhaj tshuaj tiv thaiv blasting tshuab ua kom muaj kev sib haum xeeb thiab siab- zoo nqus cov txheej txheem.
4. Rust tshem tawm kev tshuaj xyuas: nruj heev tswj hwm
Tom qab txhaj koob tshuaj tivthaiv blasting, ib nruj xeb tshem tawm kev kuaj xyuas yog nqa tawm ntawm sab hauv thiab sab nraud ntawm cov kav hlau. Cov kav dej uas tsim nyog npaj mus rau tom ntej no workstation, thaum cov uas tsis ua raws li cov qauv yuav raug kho. Cov kav dej puas lawm yog cov cim kom pom tseeb thiab hloov mus rau thaj chaw uas tau xaiv. Cov kauj ruam soj ntsuam no yog qhov tseem ceeb hauv kev tswj xyuas qhov zoo tagnrho ntawm anti- corrosion khoom.
5. Cov tshuaj tiv thaiv sab nraud - corrosion loads chaw thau khoom: Kev hloov pauv kom du
Steel kav hlau uas tau dhau lub xeb tawm los ntawm cov yeeb nkab platform mus rau txheej ceev cov kab siv cov xaim transporter. Ib zaug nyob rau hauv qhov chaw, lub vas nthiv - nraim cov menyuam los tswj tau ua kom pib cov kav tsheb thauj mus los, npaj lawv rau txheej txheem txheej txheej.
6. Dust Tshem tawm: npaj rau txheej ntawv thov txheej
Ua ntej cov hmoov txau, cov kav dej hlau yuav ua rau muaj cov hmoov av ntxiv thaum lub sijhawm cia thiab tsheb thauj mus los. Txhawm rau hais txog qhov no, tig txhuam txhuam yog siv los ntxuav cov plua tshauv nto, thiab ib lub hnab ntim plua plav sab nraud tau ua haujlwm kom tshem tawm cov khoom xoob xoob. Qhov no ua kom pom tseeb ib sab huv rau cov ntawv thov txuas ntxiv, uas yog qhov tseem ceeb rau qhov zoo ntawm cov khoom kawg.
7. Nruab nrab - zaus sov dej sov rau cov xim: melting thiab tsevneeg
Cov kab sib kis tau txav cov hlau kav hlau rau cov chaw sov. Txhawm rau kom cov hmoov epoxy rau yaj thiab gel ntawm cov yeeb nkab steel, cov kav dej yuav tsum mus txog qhov ntsuas kub tshwj xeeb. Nruab nrab - cua sov yog siv, qhov twg cov kav dej steel hla dhau los ntawm cov khoom nruab nrab eddy so ntawm lawv cov chaw, cua sov cov hlau. Feem ntau, sab hauv ntawm cov kav hlau sib tw yog rhaub rau 180 degree- 220 degree.
8. Epoxy hmoov txau: tsim cov febe txheej
Lub rhuab cov kav hlau rhaub yog tau muab txau nrog epoxy hmoov. Lub Epoxy hmoov melts, gels, thiab kho rau ntawm cov tshiab steel yeeb nkab saum npoo av, sib sau FBE txheej nrog cov kev cai uas muaj feem cuam tshuam. Cov txheej no muab cov txheej txheem pib ntawm kev tiv thaiv corrosion.
9. Adhesive Extrusion Winding: Tsim Cov Txheej Txheem Bonding
Cov txheej txheem nplaum tau thov siv cov kev tshem tawm kub -} winding txoj kev. Ib qho kev sib tw extruder melts thiab muab cov nplaum sib xyaw ua ke zoo li lub ntsej muag zoo li lub ntsej muag thiab kev hloov pauv ntawm qhov sib hloov thiab nce qib steel yeeb nkab. Daim ntawv no ib qho kev sib koom tes hauv nruab nrab nrog ib tuab ntawm 170 - 250 μm, kom ntseeg tau qhov muaj zog ntawm FBE ntawm FBE txheej thiab txheej txheej tiv thaiv txheej txheem.
10. Polyethylene Extrusion Winding: Ntxiv cov txheej txheem sab nraud
Zoo ib yam li cov nplaum extrusion winding, siab {- qhov kev sib tw polyethylene yog melded li ib tug flibbon {} {{2} {qhov ncauj tuag. Cov yeeb yaj kiab no yog tom qab ntawd txuas ntxiv mus ncig ntawm kev sib hloov thiab nce qib steel hlau yeeb nkab, ua cov txheej txheem tiv thaiv sab nraud. Cov txheej no muab kev tiv thaiv sab nraud xws li noo noo thiab kev puas tshuab kev puas tsuaj.
11. Dej Txias: Tempering Cov Kav Dej
Tom qab txheej thiab Wrapping txheej txheem, tus kav hlau hlau thiab lawv cov txheej txheem hlau yog nyob ntawm qhov kub thiab txias thiab yuav tsum tau txias txias. Txaus txias txias yog qhov tsim nyog yuav tau coj qhov kub hauv qab 60℃ua ntej cov kav dej tuaj yeem raug tshem tawm ntawm cov kab ntau lawm. Ib qho ntxiv, cov dej txias txias muaj qhov "quenching" nyhuv rau HDPE. Raws li cov ntaub pua av muaj tseeb polymer, HDPE cov qoob loo grain yog kho kom zoo los ntawm quenching, txhim kho nws txoj kev nruj.
12. Kev Tshuaj Xyuas Txheej: Ntau daim tshev rau qhov zoo
Cov txheej txheem tshuaj xyuas txheej sib piv nrog cov kev kuaj xyuas ob leeg thiab ntsuas -} siv tshuaj ntsuam. Kev tshuaj xyuas pom tseeb tsom rau qhov zoo ntawm txheej, thaum ntsuas kev ntsuas rau kev ntsuas thiab cov ntsuas cua sov siv cov tuab. Only anti - corrosion pipes that pass these inspections can move on to the end - cleaning workstation.
13. Yeeb Nkab Kawg Txheej Sib Tsoo: Zoo heev Xov
Cov anti -} corrosion kav yog muab tso rau ntawm lub tshuab beveling siv lub tsheb thauj khoom. Qhov kawg - bev bitchual txhuam yog txav los zom cov bevel, nrog bevel lub tshuaj tswj tau hauv qab 30 degree. Qhov ntev ntawm cov yeeb nkab seem ntawm cov yeeb nkab kawg raug kho raws li cov yeeb nkab taub, xws li110 - 150 hli. Cov kauj ruam no ua kom muaj kev sib txuas tsim nyog thiab ntsaws ruaj ruaj thaum cov kav dej tau nruab.
14. Cim cim thiab ntim khoom: Npaj rau cov zaub mov xa tuaj
Thaum kawg, sab hauv thiab sab nraud ntawm cov kav dej ntawm cov kav dej yog cim raws li cov qauv, thiab lawv tau qhwv nrog cov hlua hauv av ua ntej xa tawm. Qhov kev cim cim thiab cov khoom ntim ntim cov txheej txheem kom ntseeg tau tias cov khoom tuaj yeem pom tau yooj yim thiab muaj kev nyab xeeb thauj mus rau lawv lub hom phiaj.
Nrog cov txheej txheem dav dav thiab dhau los ntawm cov yeeb nkab tshiab,} Taug kev kom muaj siab {2} Muaj ntxiv dag zog rau nws txoj haujlwm hauv Giddeline Khoom lag luam.
