Ua ntej: Kev txheeb xyuas qhov kub thiab txias kub kub daim npog ntsej muag tuaj yeem hnov ​​​​ntxhiab nrog lub qhov ntswg, nrog lub qhov muag kom pom cov tsos, tab sis kuj tseem ua kom pom qhov hluav taws kub, kom pom qhov seem tom qab hlawv cov khoom.Kuj tseem tuaj yeem kuaj tau nyob rau hauv qhov kub thiab txias, ntau tshaj 260 degrees ntawm qhov kub thiab txias kom pom tias tsis muaj cov kua nplaum seem thiab lwm yam mob.

Qhov thib ob, cov nplaum nplaum nplaum ces rub tawm sai sai, koj tuaj yeem rub ib sab ntawm cov kua nplaum tawm ntawm txoj kev, koj tuaj yeem pom qhov purity thiab transparency ntawm thawj zaj duab xis.Qhov tseem ceeb tshaj plaws yog kom pom lub thickness ntawm cov kua nplaum, yog tias tsis muaj cov kua nplaum yog rub tawm los yog dotted rub sib nrug, cov kua nplaum no nyob rau hauv ib tug loj tus naj npawb ntawm impurities, cov kua nplaum tsis muaj cohesion.

Thib peb, dej ntau dhau, tau evaporated, lub sijhawm no, daim kab xev pib lub zog nplaum tau poob ntau heev, xav tias muaj peev xwm paub qhov txawv.Cov xim ntawm tag nrho cov yob ntawm daim kab xev zoo tsis ntau sib txawv ntawm cov xim ntawm ib qho rub tawm, vim tias daim kab xev zoo muaj lub ntsej muag muaj zog heev, tsis muaj xim sib tshooj.

Plaub, saib ntawm daim kab xev, daim kab xev tsuas yog tom qab slitting rau hauv cov khoom tiav yog npuas, muab tso rau ib lub lim tiam tom qab cov npuas yuav yooj yim dissipate, ntshiab tincture kua nplaum daim kab xev nto yog du, tsis muaj dawb me ntsis, tov nrog impurities nyob rau hauv daim kab xev muaj ntau qhov tsis sib xws ntawm cov pob dawb, nrog rau tes siab tsis tawg, tsis zoo ib yam li cov npuas.

Tsib, kev xaiv ntawm daim kab xev yuav tsum saib qhov dav ntawm qhov kub thiab txias daim kab xev daim kab xev thiab lub thickness ntawm daim kab xev, kev lag luam niaj hnub tsim ntawm daim kab xev daim kab xev yog siv nyob rau hauv lub siab ceev ntawm daim ntawv raj, txiav nto tsis muaj daim ntawv chips. , thiab lub thickness ntawm daim ntawv raj hauv qab 100 meters ntawm daim kab xev yog 3 hli, ntau tshaj 100 meters yog 4-5 hli.

Rau, tsis txhob hnov ​​​​qab txog qhov viscosity ntawm tes ib leeg, vim tias qhov tsis zoo ntawm daim kab xev thaum tsis muaj evaporation ntawm qhov pib nplaum quab yuam yog siab heev, siv daim kab xev los muab cov khoom thiab sai sai rub tawm kom pom lub zog tuav. , rov muab tshuaj txhuam ob peb zaug thiab tom qab ntawd kov ntawm tes, nws pom tseeb tias qhov kev xav ntawm fickle poob.
