Dip Powder Coating Thiab Spray Hmoov Txheej

1. Cov tswv yim sib txawv

1) Spray hmoov txheej:

Spray Powder txheej yog ib txoj kev kho saum npoo uas muaj cov tshuaj txau rau hauv cov khoom. Cov hmoov feem ntau yog hais txog thermosetting hmoov txheej. Qhov saum npoo ntawm hmoov-coated cov khoom yog ib qho nyuaj thiab smoother dua li cov khoom dip-coated. Electrostatic generators yog siv los them cov hmoov, uas yog ces attracted rau saum npoo ntawm cov hlau phaj. Tom qab ci ntawm 180-220 ℃, cov hmoov melts thiab adheres rau cov hlau nto. Cov khoom siv hmoov coated feem ntau yog siv rau sab hauv tsev, thiab cov xim pleev xim muaj lub tiaj tus lossis matte lossis kos duab.

2) Dip hmoov coatings:

Dip hmoov txheej muaj cov cua sov hlau thiab sib npaug nrog cov hmoov yas los ua ib zaj duab xis yas, los yog cua sov thiab dipping cov hlau rau hauv cov txheej txheej dip kom txias thiab tsim ib zaj duab xis yas ntawm cov hlau. Cov hmoov feem ntau yog hais txog thermoplastic hmoov txheej. Dip txheej yuav muab faib ua kub dip txheej thiab txias dip txheej, depending ntawm seb puas yuav tsum tau cua sov, thiab kua dip txheej thiab hmoov dip txheej, depending ntawm raw cov ntaub ntawv siv.

2. Cov txheej txheem sib txawv

1) Muaj ntau hom tshuaj tsuag hmoov txheej, xws li acrylic hmoov, polyester hmoov, thiab epoxy polyester hmoov. Cov tshuaj tsuag hmoov txheej muaj cov khoom lag luam zoo thiab qhov hnyav dua li cov hmoov nplej txheej, tab sis cov khoom nto zoo thiab du rau ob txoj kev.

2) Dip txheej yog pheej yig dua li cov tshuaj tsuag hmoov txheej vim tias tus nqi ntawm cov hmoov txheej txheej yog qis dua cov hlau. Dip hmoov txheej muaj qhov zoo ntawm kev tiv thaiv corrosion thiab xeb tiv thaiv, acid thiab alkali tsis kam, noo noo tsis kam, rwb thaiv tsev, kov zoo, kev tiv thaiv ib puag ncig, thiab kev pab lub neej ntev. Dip txheej thickness feem ntau yog tuab dua li cov tshuaj tsuag hmoov txheej, nrog lub thickness ntawm tshaj 400 microns piv rau 50-200 microns rau tshuaj tsuag hmoov txheej.

1) Dip txheej hmoov:

①Piv txwv hmoov txheej: feem ntau yog siv rau txheej khaub ncaws racks, tsheb kauj vab, pob tawb, chav ua noj, thiab lwm yam. Lawv muaj cov dej ntws zoo, gloss, thiab kav ntev.

②Engineering hmoov txheej: siv rau txheej txoj kev loj thiab railway guardrails, municipal engineering, instruments thiab meters, supermarket grids, txee hauv tub yees, cables, thiab lwm yam khoom, thiab lwm yam. Lawv muaj zog durability thiab corrosion kuj.

2) Dip txheej txheej txheem:

Dip txheej yog txheej txheem cua sov uas muaj cov hlau preheating, dipping nws hauv cov txheej txheem, thiab kho nws. Thaum lub sij hawm dipping, cov hlau rhuab sticks rau cov khoom nyob ib puag ncig. Qhov kub ntawm cov hlau, lub sij hawm dipping ntev dua, thiab lub thicker lub txheej. Qhov kub thiab cov duab ntawm cov txheej txheej yog txiav txim siab tus nqi ntawm cov yas yas uas lo rau cov hlau. Dip txheej tuaj yeem tsim cov duab zoo nkauj. Cov txheej txheem tiag tiag suav nrog kev ntxiv cov hmoov txheej rau hauv qab ntxeem tau ntim (ntws tank), uas yog agitated los ntawm compressed cua kho los ntawm lub tshuab ua kom tiav "fluidized state", tsim ib tug uniformly faib zoo hmoov.

3. Zoo sib xws 

Ob leeg yog txoj kev kho saum npoo. Cov xim ntawm ob txoj kev tuaj yeem yog daj, liab, dawb, xiav, ntsuab, thiab dub.
