Fluidized txaj hmoov txheej ua haujlwm li cas?
Fluidized txaj hmoov txheej yog txheej txheem txheej txheej txheej txheej nrog cov hmoov zoo. Cov txheej txheem cuam tshuam nrog kev ncua cov khoom siv hmoov hauv cov kwj ntawm huab cua, tsim kom muaj lub txaj fluidized ntawm cov hmoov uas tso cai rau cov txheej txheej ntawm cov substrate. Hauv tsab xov xwm no, peb yuav tshawb xyuas yuav ua li cas fluidized txaj hmoov txheej ua hauj lwm.
Cov txheej txheem ntawm fluidized txaj hmoov txheej tuaj yeem tawg ua tsib lub ntsiab stepsKev npaj substrate, hmoov thov, preheating, melting thiab curing.
Kauj Ruam 1: Kev Npaj Substrate Thawj kauj ruam hauv cov txheej txheem fluidized txaj hmoov txheej yog kev npaj substrate. Qhov no suav nrog kev tu lub substrate kom tshem tawm cov av, roj lossis lwm yam kab mob uas tuaj yeem tiv thaiv cov hmoov tsis zoo. Cov kauj ruam no yog qhov tseem ceeb rau kev ua tiav ntawm cov txheej txheem, vim tias txhua yam kab mob ntawm lub substrate tuaj yeem cuam tshuam qhov adhesion thiab durability ntawm txheej.
Kauj Ruam 2: Daim ntawv thov hmoov Thaum lub substrate yog huv si thiab qhuav, nws yog npaj rau cov hmoov daim ntawv thov kauj ruam. Cov khoom siv hmoov feem ntau yog khaws cia rau hauv lub hopper lossis lub thawv, qhov twg nws tau ntsuas tawm siv lub tshuab xa khoom. Cov cuab yeej xa khoom tuaj yeem hloov kho kom tswj tau cov hmoov hmoov, kom ntseeg tau tias cov txheej txheej tuab zoo ib yam thoob plaws lub substrate.
Kauj Ruam 3: Preheating Tom qab cov hmoov tau thov, lub substrate yog preheated. Cov kauj ruam no yog tsim nyog los yaj cov hmoov thiab tsim ib txheej txheej ntawm lub substrate. Qhov kub ntawm cov txheej txheem preheating yuav depend ntawm cov khoom siv hmoov tshwj xeeb, tab sis feem ntau yog li ntawm 180 txog 220 degrees Celsius.
Kauj Ruam 4: Melting Thaum lub substrate tau preheated, nws yog immersed nyob rau hauv lub fluidized txaj ntawm hmoov. Cov hmoov raug tshem tawm hauv cov kwj ntawm huab cua, tsim ib lub txaj fluidized uas nyob ib puag ncig lub substrate. Raws li lub substrate yog txo qis rau hauv lub txaj fluidized, cov hmoov hmoov ua raws li nws qhov chaw, tsim kom muaj txheej txheej.
Cov cua sov los ntawm cov txheej txheem preheating ua rau cov hmoov av yaj thiab ntws ua ke, tsim cov yeeb yaj kiab tas li ntawm cov substrate. Cov txheej txheem melting feem ntau yuav siv li ntawm 20 mus rau 30 vib nas this, depending ntawm lub thickness ntawm txheej thiab qhov kub thiab txias ntawm lub txaj fluidized.
Kauj Ruam 5: Kho Cov kauj ruam kawg hauv cov txheej txheem fluidized txaj hmoov txheej yog kho. Thaum cov txheej txheej tau siv lawm, nws yog rhuab mus rau qhov kub thiab txias los kho cov hmoov thiab tsim kom muaj kev ruaj khov, kav ntev. Qhov kub thiab lub sijhawm kho yuav depend ntawm cov khoom siv hmoov tshwj xeeb, tab sis feem ntau yog li ntawm 150 txog 200 degrees Celsius rau 10 mus rau 15 feeb.
Thaum lub sij hawm curing txheej txheem, cov hmoov particles crosslinks thiab chemically react los tsim ib tug khoom, check txheej uas adheres rau lub substrate. Cov txheej txheem curing yog qhov tseem ceeb rau kev ua kom cov txheej txheej ruaj khov, ua haujlwm tsis zoo, thiab tshuaj lom neeg ua haujlwm.
Hauv kev xaus, fluidized txaj hmoov txheej yog ntau yam thiab muaj txiaj ntsig ntawm txheej txheej txheej nrog cov hmoov zoo. Cov txheej txheem suav nrog kev npaj substrate, hmoov thov, preheating, melting, thiab curing, txhua qhov tseem ceeb rau kev ua tiav ntawm txheej. Los ntawm kev nkag siab yuav ua li cas fluidized txaj hmoov txheej ua haujlwm, koj tuaj yeem txiav txim siab seb cov txheej txheem no puas yog rau koj daim ntawv thov tshwj xeeb.
