Rau cov xim kab xev yog rau kev yoojyim ntawm npav thiab thaiv kev tiv thaiv, feem ntau ntau daj thiab daj lub ntiaj teb.
Insulating hluav taws xob daim kab xev
Ntau tus neeg siv cov xim kab xev raws li xim ntawm cov yeeb yaj kiab. Nyob rau hauv qhov tseeb, xim yog xim ntawm lub kua nplaum. Lub nplaum yuav muab tso thiab ces rub tawm sai sai, thiab lub nplaum ntawm ib sab yuav tsum tau tawm, kom lub purity thiab transparency ntawm thawj zaj duab xis yuav pom. Qhov tseem ceeb tshaj plaws yog kom pom qhov thickness ntawm kua nplaum. Yog hais tias tsis muaj kua nplaum los yog rub tawm, muaj ntau hom impurities hauv kua nplaum, thiab kua nplaum tsis muaj cohesion. Qhov thib ob yog tias ntau dhau heev lawm, tau ntub dej ntau lawm, thaum lub sij hawm no lub zog ua ntej ntawm daim kab xev no tau poob ntau heev, xav tias yuav daws tau. Siv daim ntawv daj rau qhov khoom. Lub thicker lub kua nplaum, qhov zoo dua qhov zoo. Piv nrog rau cov tsos ntawm daim ntaub nplaum, nws muaj qis dua, thiab xim ntawm daim ntaub nplaum nplaum yog sib sib zog nqus. Tom qab muab daim kab xev rho tawm lawm, lub hau zoo siab.
Cov xim ntawm tag nrho cov yob ntawm kab xev tsis txawv ntawm qhov ntawm ib qho tsis muaj zog, vim hais tias cov ntaub nplaum zoo zoo nkauj yog tsis tshua muaj ntxoov ntxoo thiab tsis muaj xim liab qab. Cov neeg pluag tsis zoo ntawm daim ntaub nplaum pleev doped rau daim duab BOPP, tsuas yog qhov ncaj qha mus rau cov txheej txheem rov qab, feem ntau muaj ntau cov ntsiab lus ntawm cov khoom tsis sib haum yog tsis tiav cov ntaub ntawv kaw lus, yog li cov ntaub nplaum yog siv ntau Cov kab yog tsis muaj kua nplaum). Zoo nkauj xev yog siv los hloov cov kua nplaum rau ntawm yob mos. Yog tsis muaj cov kab mob (kab rov tom ntej thiab luam tawm tsawg dua ntawm daim ntawv xev xaj uas muaj feem xyuam nrog cov ntawv xovxwm).
Lwm txoj kev ntawm kev sib txawv yog saib cov nplais ntawm daim kab xev. Tom qab daim kab xev tau muab cov khoom ua tiav lawm, nws yuav muaj cua npuas. Tom qab muab tso rau hauv ib lub lim piam, cov pa npuas yuav luag tag nrho tawm. Qhov saum npoo ntawm cov kua nplaum ntshiab nplaum nplaum yuav ua rau tsis muaj cov pob dawb dawb. Tapes uas muaj impurities muaj ntau ntawm cov pob dawb dawb muab faib dawb, uas tsis zoo li cua npuas.
Nyob rau hauv txoj kev los, peb yuav tsum tau txiav txim siab txog qhov zoo ntawm daim kab xev rau ntawm daim kab xev, thiab qhov tseem ceeb tshaj plaws rau qhov txawv ntawm qhov zoo thiab cov kab xev tsis yog xav kom muaj qhov sib luag vim hais tias doped daim kab xev tsis yog tsis hloov. Lub zog qeeb heev thaum pib ntawm lub sijhawm, yog li lo qhov khoom siv nrog daim kab xev thiab ces maj nrawm mus pom tus tuav lub zog. Rov ua ob peb zaug thiab tom qab ntawd mam li kov tes los ntawm tes yuav pom tseeb tias qhov tsis xis nyob. Doped daim kab xev nplaum yog feem ntau muaj roj thiab kua qaub thaum nws siv rau kua nplaum yas, yog li cov ntxhiab loj heev. Cov tuam txhab loj li niaj zaus siv toluene rau yaj, thiab tus kiv cua tau volatilized thaum txheej txheem txheej txheem.
