Safe Storage Of Powder Coating
Kev cia zoo rau cov hmoov txheej tiv thaiv particle agglomeration thiab cov tshuaj tiv thaiv kev nce qib, thiab ua kom muaj kev txaus siab rau daim ntawv thov, qhov no yog qhov tseem ceeb. Thaum thov hmoov txheej yuav tsum tau yooj yim fluidizable, dawb-ntws, thiab muaj peev xwm lees txais thiab tswj cov nqi hluav taws xob zoo.
Yam tseem ceeb cuam tshuam cov hmoov coatings cia
Cov yam tseem ceeb cuam tshuam rau cov hmoov txheej khaws cia tuaj yeem txheeb xyuas tau:
- Kub
- Moisture / Humidity
- Tshuaj Txau
- Mus ncaj qha tshav ntuj
Cov kev pom zoo zoo tshaj plaws rau kev khaws cov hmoov txheej yog:
- Qhov kub thiab txias <25°C
- Tus txheeb ze humidity 50 - 65%
- Nyob deb ntawm tshav ntuj ncaj qha
Cov nyhuv ntawm qhov kub thiab txias
Thaum cov hmoov raug rau ib lub sij hawm ntev mus rau qhov kub thiab txias los yog siab dua cov txheeb ze humidity tshaj qhov kev pom zoo, cov hmoov hais tuaj yeem agglomerate thiab tsim lumps. Feem ntau, cov lumps yog mos thiab crushable thiab yog nkag tau tawg los ntawm sieving ua ntej txheej. Qee qhov xwm txheej, txawm li cas los xij, nyob ntawm qib ntawm cov hmoov raug, cov lumps yuav nyuaj thiab tsis yooj yim crushable, yog li cuam tshuam rau lub sprayability ntawm cov hmoov.
Cov nyhuv ntawm noo noo
Hmoov txheej yuav tsum tau txau rau hauv qhov chaw qhuav. Yog tias cov hmoov muaj cov dej noo, yuav muaj cov kua dej tsis zoo thiab cov hmoov ntws mus rau hauv rab phom yuav tsis tas li. Qhov no tuaj yeem ua rau cov txheej tsis sib xws nrog rau qhov tsis xws luag xws li pinholes.
Kev cuam tshuam ntawm kev kis kab mob
Kev kis kab mob nrog cov plua plav hauv huab cua los yog nrog cov hmoov sib txawv ntawm cov chemistry tuaj yeem ua rau muaj qhov tsis zoo ntawm qhov chaw xws li craters, cov khoom, cov khoom tsis zoo los yog gloss variation. Yog li ntawd, cov hmoov khaws cia yuav tsum tau tiv thaiv los ntawm cov kab mob sab nraud xws li plua plav, aerosols thiab lwm yam khoom siv hauv huab cua.
Cov nyhuv ntawm lub hnub ci ncaj qha
Hnub ci ncaj qha tuaj yeem ua rau ib nrab fusion ntawm cov hmoov hmoov ua rau lumping lossis sintering.
Nyob rau hauv-txoj kev cia
- Cov hmoov coatings sab laug thaum hmo ntuj hauv lub hopper tuaj yeem nqus dej noo ua rau cov teeb meem ntawm daim ntawv thov thiab qhov tsis xws luag. Yog tias qhov no tshwm sim, cov dej noo yuav tsum tau muab tshem tawm ua ntej siv los ntawm kev ua kom cov hmoov av hauv lub hopper nrog cua qhuav ua ntej ntxiv cov hmoov tshiab.
- Qhov zoo tshaj plaws, lub hopper yuav tsum yog ze li ntawm qhov kawg ntawm txheej txheej. Thaum qhov no tsis tuaj yeem ua tau, lub hopper yuav tsum tau muab ntim nrog lub hau airtight (txog thaum cov hmoov seem rov qab mus rau tom khw) kom txwv tsis pub nqus dej.
- Hmoov seem hauv lub ntim yuav tsum tsis txhob muab tso rau hauv qhov chaw txheej txheej. Kev ntim khoom yuav tsum tau muab rov qab thiab tam sim ntawd xa rov qab mus rau chav tsev txias txias.
- Cov ntim ntim ib nrab yuav tsum tau muab rov qab kom tsis txhob muaj plua plav, av thiab cov pa paug paug.
- Cov hmoov coatings yuav tsum tsis txhob muab khaws cia rau hauv ib puag ncig ntawm txoj kab txheej los yog lub qhov cub kho kom zoo vim qhov no yuav ua rau muaj kev sib kis thiab raug kub heev.
CEEV FAJ
Kev saib xyuas ntxiv thiab kev saib xyuas yuav tsum tau ua kom ntseeg tau tias cov hmoov khaws cia zoo, tshwj xeeb tshaj yog thaum lub caij ntuj sov kub.
Nyob rau hauv rooj plaub ntawm kev xa khoom xa tuaj nrog lub sijhawm thauj mus los ntev, tus neeg siv khoom yuav tsum sib tham nrog tus neeg muag khoom txog qhov muaj peev xwm ntawm kev xa cov hmoov txheej los ntawm cov thawv txias, ua tib zoo xav txog qhov kub thiab txias thaum lub sij hawm thauj mus los thiab kwv yees kev lis kev cai tshem tawm qeeb ntawm qhov chaw.
Hauv general, hmoov txheej muaj lub txee lub neej ntawm ib xyoos txij li hnub tsim khoom muab lawv tau muab khaws cia kom zoo raws li cov lus qhia saum toj no, tshwj tsis yog hais tias lwm yam hauv cov ntaub ntawv cov khoom siv.
