I. Kev cuam tshuam rau xim kev ua haujlwm thiab kev ua haujlwm zoo
1. Paint Film Defects: Residual impurities (xws li cov pleev xim qhuav, plua plav, thiab noo noo) sib xyaw rau hauv cov xim tshiab tuaj yeem ua rau cov khoom zoo li -xws li, npuas, sagging, los yog txiv kab ntxwv -peel- zoo li cuam tshuam thaum lub sij hawm txau, cuam tshuam rau qhov smoothness thiab zoo nkauj ntawm cov xim pleev xim.
2. Xim Deviation: Yog tias cov xim pleev xim lossis xim masterbatch tau siv yav dhau los, tsis ua kom huv si kom huv tuaj yeem ua rau cov xim tshiab, ua rau muaj xim sib txawv, tshwj xeeb tshaj yog pom hauv tsheb refinish xim qhov tseeb xim yog qhov tseem ceeb heev.
3. Tshuaj Reaction Risk: Cov kuab tshuaj residual lossis hardeners tuaj yeem cuam tshuam nrog cov xim tshiab, ua rau gelling, delamination, lossis xim tsis ua haujlwm, txo qhov adhesion thiab durability.
II. Khoom siv thiab cuab yeej puas
1. Spray Gun Clog: Cov impurities nkag mus rau hauv cov xim pleev xim tuaj yeem yooj yim clog nozzles, cuam tshuam rau atomization, ua kom cov khoom tu ntau zaus, thiab tseem ua rau muaj kev puas tsuaj siab - cov khoom siv tsis muaj cua tsis zoo.
2. Shortened Tool Life: Cov kaus poom qias neeg tuaj yeem qhia cov khoom corrosive, ua kom cov oxidation ntawm cov hlau thiab cuam tshuam rau lub neej ntawm cov cuab yeej siv.
III. Ntxiv Losses Thaum Tsim Kho: Cov kaus poom xim tsis huv ua rau tsis muaj txiaj ntsig thaum tsim kho. Piv txwv li, impurities nyob rau hauv cov xim yuav tsum tau rov pom thiab kho, los yog tsuag tsuag nyuaj ua rau repetitive ua hauj lwm, ua kom cov ntaub ntawv pov tseg, deviating tus nqi txheej ntawm lub theoretical tus nqi, thiab tsa cov xim tsis coefficient.
IV. Safety and Environmental Hazards:
1. Volatile Harmful Gases: Cov kuab tshuaj seem tsis tu ncua tso cov tshuaj lom tsis zoo xws li cov tshuaj benzene thiab halogenated hydrocarbons. Ntev-ntev ntev yuav ua rau muaj kev noj qab haus huv ntawm cov neeg ua haujlwm, ua rau kiv taub hau, ua pa ua pa, lossis ua rau muaj mob ntev.
2. Kev pheej hmoo hluav taws kub: Cov khoom siv hluav taws xob sib xyaw ua ke hauv qhov chaw kaw thiab tuaj yeem ua rau kub hnyiab lossis tawg thaum sib cuag nrog qhov kub thiab txias los yog qhib nplaim taws, tshwj xeeb tshaj yog nyob rau hauv qhov chaw ua haujlwm tsis zoo.
3. Kev ua qias tuaj ib puag ncig: Kev pov tseg tsis zoo ntawm cov kaus poom tsis huv yuav ua rau cov khoom seem nkag mus rau hauv av lossis dej hauv lub cev, ua rau muaj kuab paug rau ib puag ncig thiab ua txhaum HW49 qeb kev tswj hwm hauv National Hazardous Waste List.
V. Kev ua tsis tau raws li cov qauv kev rov ua dua tshiab thiab rov siv dua: Cov xim khib nyiab tuaj yeem siv tsis tau yog tias lawv tsis huv huv. Cov dej tsis huv-raws li cov kaus poom xim yuav tsum tau ntxuav tag nrho ntawm cov khoom seem thiab qhuav ua ntej lawv tuaj yeem rov ua dua li cov hlau seem; cov kuab tshuaj-raws li cov kaus poom xim yuav tsum tau muab pov tseg los ntawm cov tuam txhab pov tseg kev puas tsuaj, txwv tsis pub muaj kev pheej hmoo raug cai yuav tshwm sim.
