Txiav tawm qhov hluav taws kub.Hnav cov cuab yeej ua pa ntawm tus kheej thiab cov khaub ncaws tiv thaiv hluav taws.Thaiv qhov xau hauv qab kev nyab xeeb.Cov tshuaj tsuag dej kom tsis txhob evaporation.Sib tov thiab nqus nrog xuab zeb lossis lwm yam tsis-combustible adsorbent.Tom qab ntawd lawv raug thauj mus rau qhov chaw khoob rau faus, evaporation, lossis incineration.Xws li cov dej xau ntau, kev siv cov kwj deg vaj tse, thiab tom qab ntawd sau, hloov, rov ua dua lossis tsis muaj kev puas tsuaj tom qab pov tseg.
kev tiv thaiv
Thaum lub siab concentration nyob rau hauv huab cua, yuav tsum tau hnav lub npog ntsej muag roj.Nws raug nquahu kom hnav lub tshuab ua pa ntawm tus kheej thaum muaj xwm txheej ceev lossis khiav tawm.
Kev tiv thaiv qhov muag: hnav cov tshuaj tiv thaiv kev nyab xeeb qhov muag
Feem ntau yog siv los ua cov organic hluavtaws monomer, siv rau hluavtaws cob, plastics, coatings, luam ntawv number case, adhesives, lubricating roj additives, cov ntaub ntawv kho hniav, fiber ntau tus neeg sawv cev, tus neeg sawv cev ntawv, thiab lwm yam.
Txoj kev khaws cia: khaws cia hauv qhov chaw txias, qhov cua txias.Lub tsev qiv ntawv kub yuav tsum tsis pub tshaj 37 ℃.Nyob deb ntawm qhov hluav taws kub thiab qhov chaw kub.Ntim yuav tsum raug kaw thiab yuav tsum tsis txhob sib cuag nrog huab cua.Yuav tsum tau muab cais los ntawm oxidant, acid, alkali, tsis txhob sib xyaw cia.Yuav tsum tsis txhob muab khaws cia rau hauv qhov ntau lossis khaws cia rau lub sijhawm ntev.Kev tawg-pov thawj-hom teeb pom kev zoo thiab qhov cua qhov chaw tau txais yuav.Tsis siv cov cuab yeej siv tshuab thiab cov cuab yeej ua rau lub txim taws.Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev thiab cov khoom siv vaj tse tsim nyog.
