Kev tswj cov dej noo hauv MDF yog qhov tseem ceeb
Cov txheej txheem hmoov txheej yuav tsum tau them nyiaj electrostatic rau cov hmoov kom nyiam cov ntoo thaum siv cov qib hwm MDF. Qhov no electrostatic nqi yog tsim los ntawm cua sov cov ntoo kom coj cov dej noo nyob rau saum npoo, vim nws yog cov dej noo uas ua hauj lwm raws li electrostatic conductor.Qhov adhesion ntawm cov hmoov rau lub rooj tsavxwm yog muaj zog heev kom tshem tawm cov hmoov tag los ntawm lub rooj tsavxwm. Nws zoo li MDF board substrate yuav nti tawm ua ntejNyeem ntxiv…
ABS yas txheej yog dab tsi
ABS yas txheej ABS yas Department ntawm butadiene - acrylonitrile - styrene terpolymer, dav siv hauv kev tsim cov khoom siv hauv tsev, vaj tse thiab tsheb thiab maus taus qhov chaw. Ketone, benzene thiab ester hnyav muaj peev xwm ua kom tawg ABS yas, cawv thiab hydrocarbon solvent dissolution ntawm ABS yas, yog li cov noob.ral kev siv ethanol - isopropanol hnyav rau kev kho mob saum npoo, feem ntau yog siv cov tshuaj txau lossis electrostatic txau txheej txheem rau kev tsim kho. ABS yas txheej xim muaj ntau yam kev xaiv raws li thermoplastic acrylic txheej,Nyeem ntxiv…
Qee yam tseem ceeb rau polyester txheej degradation
Polyester degradation yog cuam tshuam los ntawm hnub ci hluav taws xob, photocatalytic admixtures, dej thiab noo noo, tshuaj, oxygen, ozone, kub, puas, sab hauv thiab sab nraud kev nyuaj siab, thiab pigment fading.Tau ntawm tag nrho cov no, cov nram qab no yam, tag nrho cov tam sim no nyob rau hauv sab nraum zoov huab cua, yog Qhov tseem ceeb tshaj plaws rau txheej degradation: noo noo, kub, oxidation, UV hluav taws xob. Moisture Hydrolysis tshwm sim thaum cov yas raug dej los yog cov av noo.Qhov tshuaj tiv thaiv no yuav yog ib qho tseem ceeb ntawm kev degradation ntawm condensation polymers xws li polyesters, qhov twg ester pawg.Nyeem ntxiv…
Taw qhia ntawm Fusion bonded epoxy hmoov txheej
Fusion bonded epoxy txheej, tseem hu ua fusion-bond epoxy hmoov txheej thiab feem ntau hu ua FBE txheej, yog epoxy raws hmoov txheej uas tau dav siv los tiv thaiv cov yeeb nkab steel siv hauv kev tsim cov kav dej, cov pob zeb ua kom muaj zog (rebar) thiab ntawm ib qho ntau yam ntawm cov kav dej sib txuas, li qub thiab lwm yam los ntawm corrosion. FBE txheej yog thermoset polymer txheej. Lawv tuaj nyob rau hauv qeb ntawm 'tiv thaiv txheej' hauv cov xim thiab txheej nomenclature. Lub npe 'fusion-bond epoxy' yog vim muaj cov khoom sib txuas sib txuas thiabNyeem ntxiv…
Chromate txheej rau aluminium nto
Aluminium thiab aluminium alloys yog kho los ntawm corrosion resistant conversion txheej uas hu ua "chromate txheej" los yog "chromating". General txoj kev yog los ntxuav cov txhuas saum npoo thiab tom qab ntawd siv cov acidic chromium muaj pes tsawg leeg ntawm qhov huv si. Chromium hloov dua siab tshiab coatings yog heev corrosion resistant thiab muab zoo heev tuav ntawm cov txheej tom ntej. Cov txheej txheem sib txawv ntawm cov txheej txheem tom ntej tuaj yeem siv rau cov txheej txheem hloov pauv chromate kom tsim tau qhov chaw txaus. Qhov peb hu ua phosphating rau steel hlau yogNyeem ntxiv…
Hmoov txheej tshaj cov khoom tsis yog hlau xws li ntoo yas
Tshaj nees nkaum xyoo dhau los, hmoov txheej tau hloov pauv kev lag luam tiav los ntawm kev muab cov khoom zoo tshaj, ruaj khov, ib puag ncig tus phooj ywg, tshwj xeeb tshaj yog rau cov khoom siv hlau xws li cov khoom siv, cov khoom siv tsheb, cov khoom ua si thiab lwm yam khoom siv suav tsis txheeb.Txawm li cas los xij nrog kev tsim cov hmoov txheej uas tuaj yeem siv tau thiab kho tau ntawm qhov kub thiab txias, kev lag luam tau qhib rau cov cua sov substrates xws li yas thiab ntoo. Radiation curing (UV lossis electron beam) tso cai rau kev kho cov hmoov ntawm cov cua sov substrates los ntawm kev txo qis.Nyeem ntxiv…
Qhov zoo ntawm UV hmoov txheej tshuab
UV hmoov txheej hmoov formulations muaj xws li: UV hmoov resin, Photoinitiator, Additives, Pigment / extenders. Kev kho cov hmoov txheej nrog UV teeb tuaj yeem piav qhia tias "qhov zoo tshaj plaws ntawm ob lub ntiaj teb". Txoj kev tshiab no ua rau nws muaj peev xwm tau txais txiaj ntsig los ntawm qhov zoo ntawm kev kho mob ceev thiab kev kho tsis tshua muaj qhov kub thiab txias nrog rau ib puag ncig tus phooj ywg. Qhov zoo ntawm UV curable hmoov tshuab yog: Cov nqi qis qis Daim ntawv thov ntawm ib txheej Cov hmoov siv ntau tshaj plaws nrog cov khoom siv rov ua dua tshiab Tsis tshua muaj kev kho kub siab kho ceev HardlyNyeem ntxiv…
