Kev hloov pauv hauv cov iav cawv cawv

Cov kev hloov pauv hauv cov khoom siv tes ua cawv txiv hmab hauv lub neej txhua hnub, cov iav fwj tuaj yeem pom nyob txhua qhov chaw. Txawm hais tias nws yog dej haus, tshuaj, tshuaj pleev ib ce, thiab lwm yam, cov tshuaj iav fwj yog lawv cov neeg koom tes zoo. Cov iav ntim ntim no ib txwm tau suav tias yog cov khoom ntim zoo vim tias lawv cov pob tshab zoo nkauj, zoo tshuaj lom neeg ruaj khov, tsis muaj kuab paug rau cov ntsiab lus, tuaj yeem ua rau kub kub, thiab cov fwj qub tuaj yeem siv thiab rov siv dua. Txawm li cas los xij, txhawm rau txhawm rau sib tw nrog cov khoom ntim xws li cov kaus poom hlau thiab lub raj mis yas, cov tshuaj iav fwj tau txhim kho lawv cov thev naus laus zis ntau lawm los ua cov khoom lag luam zoo, zoo nkauj tsos thiab tus nqi qis. Tom qab kev tsim kho tshuab ntawm regenerative iav furnaces, iav melting technology tau ushered nyob rau hauv lub thib ob kiv puag ncig, uas yog oxy-combustion tshuab. Hauv kaum xyoo dhau los, kev coj ua ntawm ntau lub teb chaws hauv kev hloov cov thev naus laus zis ntawm cov iav melting furnaces tau pom tias oxy-combustion technology muaj txiaj ntsig zoo xws li kev nqis peev tsawg, kev siv hluav taws xob tsawg, thiab cov pa phem tsawg. Hauv Tebchaws Meskas thiab Tebchaws Europe, lub raj mis thiab cov kaus poom tau dhau los ua cov khoom lag luam rau iav fwj thiab cov kaus poom. Me-lub qhov ncauj tshuab tshuab (NNPB) thiab kub thiab txias kawg tshuaj tsuag tshuab rau lub raj mis thiab cov kaus poom yog tag nrho cov teeb yuag technologies. Lub tuam txhab German tau tsim tau 1-liter concentrated kua txiv lub raj mis uas hnyav 295 grams xwb. Qhov saum npoo ntawm lub raj mis yog coated nrog cov organic resin, uas tuaj yeem ua rau lub zog siab ntawm lub raj mis los ntawm 20%. Hauv lub Hoobkas niaj hnub no, kev tsim cov iav fwj tsis yog ib txoj haujlwm yooj yim, thiab muaj cov teeb meem kev tshawb fawb los daws.
