1.Cov khoom ntws qab phab ntsa:
Yog vim li cas: Cov khoom siv nrawm nrawm, lossis cov khoom siv atomization tsis zoo, thiab cov tshuaj tsuag tsis sib xws.
Kev daws: Kho cov khoom siv, ua kom cov cua kub ntawm cov kav dej, thiab txhim kho cov cua sov ntawm cov khoom siv.
2.Uneven ua npuas ncauj nto:
Yog vim li cas: Qhov ceev ntawm cov khoom tsis sib koom ua ke, lub nozzle yog deformed, thiab cov txheej yog tuab heev ntawm ib lub sij hawm.
Kev daws: Kho cov cuab yeej siv, ntxuav cov khoom seem hauv lub nozzle, thiab ua kom cov huab cua siab.
3.Cov khoom tsis yog tawm ntawm lub square thiab tus nqi qis:
Yog vim li cas: Qhov chaw nyob ib puag ncig yog hnyav, qhov kub thiab txias ambient yog tsawg, cua ceev yog loj, thiab cov khoom yog blackened. Muaj ntau qhov laj thawj tuaj yeem ua rau qhov tshwm sim ntawm cov zis qis.
Kev daws: Ua kom qhov kub thiab txias ntawm cov khoom siv, thaum tiv thaiv lub qhov rais qhov rooj kom txo tau qhov poob, thiab txo kev tsim kho hauv huab cua.
4.Cov khoom tsis zoo sib raug zoo:
Ua rau: Lub substrate yog qias neeg los ntawm hmoov av thiab qhov kub ntawm lub hauv paus txheej yog tsawg.
Kev daws: Purify lub substrate kom qhov kub thiab txias ntawm lub hauv paus txheej.
5. Thaiv phom:
Yog vim li cas: Cov khoom dawb muaj impurities lossis cov khoom siv dub nkag mus rau hauv dej thiab crystallizes, nrog rau qee qhov tshwm sim ntawm cov khoom siv ib nrab.
Kev daws: Txo cov cua kub ntawm cov khoom siv, thiab tib lub sij hawm xyuas seb cov khoom siv dub thiab dawb cov kav dej yog txhaws nrog impurities.
