Taw qhia rau Silicon Steel Txheej Txheej Txheem (1)

GNEE Oriented Silicon hlau

Piv nrog kub dov silicon steel los xij,txias-kuav los tiag silicon steelcov nplooj ntawv muaj qhov pom tseeb ntawm kev coated nrog ib txheej txheej ntawm txheej txheej thaum lub sijhawm tsim khoom. Cov txheej no tsis tsuas yog muaj cov khoom siv hluav taws xob siab, tab sis kuj muaj kev tiv thaiv corrosion thiab kev ua haujlwm. , zoo kub tsis kam, txheej txheej ntawm oriented steel tuaj yeem txhim kho cov khoom sib nqus. Lub interlayer rwb thaiv tsev ntawm cov tiav kub dovsilicon steel ntawvFeem ntau yog ua tiav los ntawm soaking hauv cov kua roj vanish thiab pickling thiab ces ziab. Cia kuv qhia koj txog txheej txheej ntawm silicon steel:

Lub insulating txheej tam sim no siv raunon-oriented silicon hlauyog ib qho inorganic-organic hybrid insulating txheej, hu ua semi-organic txheej (T4 chromate-organic resin): T0: dej, boric acid (H3BO3), chromic anhydride (CrO3), Additives, thiab lwm yam. ; T0 lub ntiajteb txawj nqus (1.161 ~ 1.175g / cm3, 25 degree ).

Cov laj thawj tseem ceeb cuam tshuam rau qhov zoo ntawm cov dej txheej txheej

(1) Qhov kub thiab txias

Raws li qhov kub thiab txias, lub sij hawm cia zoo ntawm T4 txheej kua ua kom luv, xws li 10 degree -5 hnub, 20 degree -3 hnub, thiab 30 degree -2 hnub.

(2) Kev cuam tshuam ntawm lub sijhawm

Nyob rau tib lub sijhawm, cov xim ntawm cov kua txheej txheej yuav tsaus thiab tsaus, thiab thaum kawg deteriorates thiab yog scrapped. Vim muaj kev cuam tshuam ntawm qhov kub thiab txias ntawm cov kua txheej txheej, txheej txheej txheej txheej muaj cov tub yees cais, siv dej ua qhov nruab nrab. Lub twj tso kua mis ntws dhau dej txias rau hauv txhua qhov chaw txias (nrog rau lub tank ncig thiab lub tank cia). Muaj cov raj zoo li tus nab muab faib rau hauv lub tank, thiab cov dej txias Nruam kev ncig hauv lub raj ua kom qhov kub thiab txias ntawm cov dej txheej.<20°C. This ensures the freshness of the coating fluid.

Vim yog lub sijhawm cuam tshuam ntawm cov kua txheej txheej, cov kua txheej yuav tsum tau siv sai li sai tau thaum lub sijhawm tsim khoom, thiab tom qab ntawd cov txheej txheem tshiab yuav tsum tau ntxiv los tiv thaiv cov txheej txheem ua kua los ntawm kev ua kom tsis zoo thiab ua rau cov txheej txheem tsis zoo; Thaum lub tsev ntsib qhov tsis ua hauj lwm thiab kev saib xyuas, nws yuav tsum Nrho cov txheej txheem installation, tam sim ntawd nchuav cov kua txheej hauv lub tank thiab lub tank cia, thiab yaug nrog dej kom tiv thaiv cov kua txheej los ntawm clumping thiab clogging lub twj tso kua mis thiab cov kav dej tom qab deterioration.

(3) Txheej tswj tus nqi

Txheej txheej: Qhov hnyav ntawm txheej ib chav tsev ntawm cov hlau sawb, hauv g / m2. Txhawm rau kom ntseeg tau tias kev ua tau zoo ntawm txheej txheej, ntau txheej txheej yuav tsum tau sim ua ntej txhawm rau txiav txim siab lub hom phiaj tus nqi thiab kev tswj hwm ntau ntawm cov txheej txheem zoo.

Yam cuam tshuam rau txheej txheej

(1) Lub ntiajteb txawj nqus tshwj xeeb ntawm cov kua txheej txheej: qhov siab dua qhov tshwj xeeb lub ntiajteb txawj nqus, ntau dua cov txheej txheej;

(2) Chav tsev ceev: Txij li cov menyuam txheej txheej yog cov menyuam hauv qab no, cov txheej txheem yog proportional rau chav tsev ceev. Qhov siab dua qhov ceev, qhov tuab ntawm txheej txheej;

(3) Kev txo qis ntawm cov menyuam txheej: Cov txheej txheem txheej txheem yog inversely proportional rau txo cov txheej txheej. Qhov ntau dua qhov kev txo qis, qhov thinner lub txheej;

(4) Cov menyuam zoo li cov menyuam txheej txheej: Cov menyuam txheej txheej yog ua los ntawm cov kua qaub-resistant roj hmab. Cov menyuam cov yam ntxwv muaj xws li hardness, txoj kab uas hla, lub kaum sab xis, qhov tob, tus naj npawb ntawm cov hniav, thiab lwm yam ntawm cov menyuam roj hmab. Qhov loj thiab tob qhov zawj, cov hniav ntau dua, thiab cov txheej tuab dua.

Cov cuab yeej hauv paus ntsiab lus ntawm txheej cov menyuam

(1) Sim xaiv tib tus qauv ntawm txheej txheej rau cov menyuam vim yog cov yam ntxwv ntawm cov menyuam;

(2) Vim yog cov nyhuv ntawm lub ntiajteb txawj nqus, cov txheej txheej ntawm qhov chaw qis yog qhov nyias nyias, yog li cov txheej txheem txheej txheej nrog lub siab hardness, me me txoj kab uas hla, thiab qhov sib sib zog nqus grooves yuav tsum tau siv raws li cov menyuam hauv qab;

(3) Cov txheej txheej txheej yuav tsum tau hloov ua khub.

Kho lub kaum sab xis ntawm cov tshuaj tsuag thiab tshuaj tsuag tus nqi ntawm cov kua txheej

Ntawm lawv, cov lus qhia txhaj tshuaj ntawm c thiab e yog qhov tseeb, lwm cov lus qhia yuav ua rau cov txheej txheem tsis zoo.

Lub hauv paus ntsiab lus ntawm kev kho lub kaum sab xis thiab cov tshuaj tsuag ntim ntawm cov kua txheej yuav tsum xyuas kom meej tias cov kua txheej txheej yog txau kom zoo thiab sib npaug mus rau cov txheej txheej cov menyuam tsis muaj kev cuam tshuam, thiab tiv thaiv cov tshuaj tsuag ntawm cov kua txheej los ntawm siab dhau los yog cov tshuaj tsuag kev taw qhia ntawm txheej kua header. Tau txau tsis raug. Txhawm rau tsim cov npuas, nws tseem tsim nyog los tiv thaiv lub siab txau ntawm cov kua txheej los ntawm qhov qis dhau los yog cov kev taw qhia ntawm cov txheej txheem ntawm cov kua hauv lub taub hau tsis raug, ua rau tsis muaj tshuaj tsuag ntawm cov kua txheej los yog tshuaj tsuag rau ntawm cov menyuam txheej, uas ua rau muaj kev cuam tshuam ntawm cov txheej txheem. txheej tsis xws luag xws li cov txheej uas ploj lawm thiab qhov chaw.

Ua rau thiab Countermeasures ntawm Main Defects hauv Coatings

(1) Tsis muaj txheej:

Yog vim li cas: Nws yog tshwm sim los ntawm clogging ntawm nozzles, headers, ncig twj tso kua mis thiab lwm yam khoom siv, tsis yog tshuaj tsuag lub kaum sab xis ntawm cov kua txheej txheej los yog dej txheej tsis txaus.

Countermeasures: Tshawb xyuas ntau zaus thaum ua haujlwm, tshem tawm thiab ntxuav lub taub hau hauv lub sijhawm, thiab kho qhov kev txhaj tshuaj thiab lub kaum sab xis ntawm lub taub hau.

(2) Ob kab:

Yog vim li cas: Lub ntiajteb txawj nqus ntawm cov kua txheej yog siab dhau lawm; lub viscosity ntawm cov kua txheej yog siab; lub hardness ntawm cov menyuam txheej yog siab; qhov txo qis ntawm cov menyuam txheej txheej yog me me.

Countermeasures: nruj me ntsis standardize lub kua npaj ua hauj lwm, thiab tswj qhov feem ntawm cov txheej txheej kua nyob rau hauv lub hom phiaj raws li tus txheej txheem; tsim nyog tswj qhov kub ntawm cov kua txheej txheej. High-temperature txheej cov kua yog qhov ua rau muaj kev laus, tab sis yog tias qhov kub thiab txias tsis dhau, cov viscosity ntawm cov kua txheej yuav siab thiab nws yuav kis tau thaum lub sij hawm txheej. Maj mam, ob kab yog tsim (qhov zoo tshaj qhov kub yog 10-20 degree ); txheej txheej cov menyuam muaj siab hardness, thiab ob kab yog yooj yim ua thaum txheej. Yog li ntawd, cov menyuam txheej txheej nrog lub hardness qis yuav tsum tau xaiv raws li qhov ceev ntawm chav tsev, thiab cov menyuam txheej txheej yuav tsum tau xaiv raws li qhov tseeb txheej txheej. Tsim nyog kho tus nqi ntawm cov menyuam txheej txheej.

(3) Lub suab tsis sib xws:

Ua rau: tsis zoo alkali tu, roj stains ntawm steel phaj; txheej tsis sib xws; kev laus ntawm cov menyuam txheej; tsis tsim nyog ziab thiab tua hluav taws kub tswj, thiab lwm yam.

Countermeasures: Txhim kho qhov zoo ntawm alkali ntxuav; nruj me ntsis tswj cov txheej txheem raws li cov txheej txheem txheej, thiab kho qhov txo qis ntawm cov txheej txheem txheej txheem kom paub meej tias cov txheej txheem ntawm tag nrho cov phaj hlau yog tswj nyob rau hauv lub hom phiaj, nrog rau qhov sib txawv me me li sai tau, li no kom cov txheej txheem. Hnav khaub ncaws; Yog tias cov txheej txheej tau pom tias muaj kev laus, cov txheej txheej cov menyuam yuav tsum tau hloov lub sijhawm, thiab qhov kub thiab txias ntawm qhov ziab thiab sintering rauv yuav tsum tau tswj kom tsim nyog raws sijhawm raws li kev hloov pauv hauv chav tsev ceev.
