Sab nraum PE composite coated yas yeeb nkab
Sab nraum PE composite coated yas yeeb nkab, Coated (dov) yas composite steel yeeb nkab tsis muaj txoj kab uas hla kev txwv, lub thickness ntawm lub hauv ob sab phlu txheej kuj yuav arbitrarily xaiv, raws li cov corrosion nruab nrab tej yam kev mob, xaiv txawv hauv ob sab phlu thickness, ntev kuj mus txog 6-12. meters;Tib lub nominal txoj kab uas hla, coated (dov) yas composite steel yeeb nkab hauv ob sab phlu yog feem ntau ntawm 0.5-1mm, du tube nto, tsis tsuas yog cov kev sib txhuam coefficient me me, thiab kev sib txhuam coefficient kuj me me, cov kua dej poob hauv lub raj me me, qhov kis tau tus mob yog loj, kom ua tiav lub zog txuag.Nyob rau hauv xyoo tas los no, cov kav dej los tiv thaiv cov kav hlau tsis zoo yog siv dav hauv kev tsim cov dej thiab cov kav dej, cov dej haus faib cov kav dej engineering, hluav taws xob tswj hluav taws xob, rau feem ntau cov hluav taws xob kav steel yeeb nkab ua ntej siv kub dip galvanized steel yeeb nkab, ntau lub zej zog, tsev so, Cov tsev ua haujlwm tam sim no siv epoxy hmoov anticorrosive steel yeeb nkab nrog ob sab yas coated yog siv rau ob sab hauv thiab sab nraud raws li cov khoom siv hluav taws xob, nws cov tsos zoo nkauj thiab ruaj khov, Nws tau dhau los ua cov khoom lag luam loj ntawm kev lag luam tawm hauv lub xyoo pua 21st.PE sab hauv EP coated yas steel tube kev muag khoom ntawm cov hmoov coated yas steel tube ntxiv nplaim retardant thiab hloov epoxy resin hmoov, qhov kub tsis kam ntawm txheej yog superior, nyob rau hauv ntev siv tsis hlawv, tsis txhob soften.
Sab nraum Pe Composite Coated Yas Yeeb Nkab, Qhov Zoo
Cov xim zaj duab xis ntawm epoxy hmoov anticorrosive steel raj yog tawv, dej resistant thiab tsis muaj tshuaj lom.Muaj zog adhesion, zoo adhesion ntawm cov xim zaj duab xis thiab xim zaj duab xis.Zoo heev los tiv thaiv xeb thiab dej tsis kam, kev siv cov khoom siv los tiv thaiv xeb zoo heev, los xyuas kom meej nws cov kev ua haujlwm tiv thaiv xeb.Nws muaj zoo mechanical zog, tawv zaj duab xis, abrasion kuj thiab cuam tshuam tsis kam.Cov ntsiab lus siab, tuab zaj duab xis.Cov qauv molecular ntawm epoxy hmoov anticorrosive steel yeeb nkab yog tus cwj pwm los ntawm cov active epoxy pawg hauv cov saw molecular, uas tuaj yeem nyob rau ntawm qhov kawg, nruab nrab lossis lub nplhaib qauv ntawm cov saw molecular.
Vim yog cov epoxy active pawg nyob rau hauv cov qauv molecular, lawv muaj peev xwm crosslink nrog ntau hom curing tus neeg sawv cev los tsim insoluble thiab infusible polymers nrog peb-txoj kev network qauv.Thermosetting hmoov txheej yog tsuas yog siv nyob rau hauv ntau lub teb chaws: epoxy hmoov txheej, epoxy phenolic hmoov txheej, polyester hmoov txheej, epoxy-polyester hmoov txheej.Ntawm lawv, epoxy hmoov txheej yog ntau yam ntawm daim ntawv thov, tseem yog tam sim no zus tau tej cov yas hmoov txheej, dav siv nyob rau hauv electrostatic txau txheej txheem, nyob rau hauv cov hniav txheej plays ib tug tseem ceeb heev txoj hauj lwm;Vim nws cov tshuaj tiv thaiv corrosion siab, epoxy phenolic hmoov txheej feem ntau yog siv los tiv thaiv corrosion txheej.
Thermoplastic Powder Coatings Feem ntau
Polyethylene hmoov txheej, POLYvinyl chloride hmoov txheej, polypropylene hmoov txheej, chlorinated polyether hmoov txheej, nylon hmoov txheej, polyphenylene sulfide hmoov txheej, thiab lwm yam, cov thermoplastic hmoov txheej muaj qhov zoo thiab qhov tsis zoo.Thermosetting plastics muaj kev kho kom zoo dua qub thiab ntub dej vim tias lawv qhov hnyav molecular, uas ua rau lawv muaj zog adhesion rau lub raj lub cev thaum txheej steel tube, thiab tuaj yeem ua rau coated steel tube tau ib tug du yas zaj duab xis nto.Feem ntau siv cov thermosetting yas yog: epoxy resin, phenolic resin, amino resin thiab lwm yam.Lub thickness ntawm phab ntsa txheej yog nruab nrab ntawm 100 microns thiab 500 microns, feem ntau yog 350 microns.
Sab nraum PE composite coated yas yeeb nkab, 1. Kev noj qab haus huv, tsis muaj tshuaj lom, tsis muaj scaling, tsis muaj kev yug me nyuam ntawm cov kab mob, ua kom cov kua dej zoo 2. 3. Cov txheej txheem installation yog paub tab, yooj yim thiab ceev, thiab kev sib txuas nrog cov yeeb nkab zoo tib yam galvanized yog tib yam.4. Cov huab cua tsis zoo.5. Smooth yeeb nkab phab ntsa, txhim kho conveying efficiency, ntev kev pab cuam lub neej.
Sab nraum PE composite coated yas yeeb nkab, Kev sib txuas hom:xov kev sib txuas: siv phau ntawv tuag twisted hlau los yog hluav taws xob lub tes tsho tshuab ua cov yeeb nkab xov, xyuam xim rau cua txias thaum ua haujlwm;Flange kev twb kev txuas, nyob rau ntawm qhov chaw ntsuas, kos duab kav ib kab ua daim ntawv qhia, txheej txheej, yas hauv ob sab phlu, thiab ces thauj mus rau qhov chaw installation;Tsis-coated, lined yas steel yeeb nkab thiab yeeb nkab fittings yuav siv tau nyob rau hauv lub teb, flange welding, assembling pipeline, thiab ces disassembled rau txheej, lined yas ua, thiab ces thauj mus rau lub site installation;Ua tiav grooved coated yas yeeb nkab fittings yuav tsum nyiam;Grooves yuav tsum tau nias los ntawm groove dov tshuab, thiab cov grooves yuav tsum ua raws li cov qauv tsim nyog.
