Txiav tawm qhov hluav taws kub. Hnav tus kheej uas muaj ua pa hloov kho cov khaub ncaws thiab cov khaub ncaws hluav taws kub tiv thaiv hluav taws kub. Thaiv qhov xau nyob rau hauv kev nyab xeeb. Dej tsuag ua kom muaj cua kom tau evaporation. Sib tov thiab nqus nrog xuab zeb lossis lwm yam tsis sib luag adsorbent. Lawv tab tom thauj mus rau qhov chaw khoob rau kev faus neeg, evaporation, lossis kev ua kom sib cais. Xws li cov dej xau ntau, kev siv ntawm cov chaw nkaum ntawm lub tsev, thiab tom qab ntawd sau, hloov chaw, rov ua dua tshiab tom qab pov tseg.
kev tiv thaiv kev tiv thaiv
Ntawm qhov siab siab hauv huab cua, daim npog roj yuav tsum hnav. Nws raug nquahu kom hnav ib qho kev ua pa rau tus kheej rau tus kheej
Kev tiv thaiv qhov muag: hnav cov tshuaj tiv thaiv kev nyab xeeb tshuaj tiv thaiv kev nyab xeeb
Mas siv los ua cov organic hluavtaws monomer, siv rau cov ntaub ntawv hluavtaws, cov khoom siv hniav, cov ntaub ntawv kho hniav, tus neeg saib xyuas fiber ntau, thiab lwm yam.
Kev Cia Cov Txheej Txheem: Khw hauv qhov chaw txias, tshuab ua kom muaj zog. Lub tsev qiv ntawv ntsuas kub yuav tsum tsis pub tshaj 37 ℃. Txav deb ntawm hluav taws kub thiab cua sov. Ntim yuav tsum tau muab khi thiab yuav tsis muaj kev sib cuag nrog huab cua. Yuav tsum tau muab cia cais tawm ntawm oxidant, acid, alkali, zam kev sib xyaw. Yuav tsum tsis txhob muab cia rau hauv cov khoom loj lossis khaws cia ntev ntev. Tawg-pov thawj-hom teeb pom kev zoo thiab kev nyab xeeb rau cov chaw tau txais. Tsis muaj kev siv cov cuab yeej siv txhua yam thiab cov cuab yeej sib txawv rau txim. Thaj chaw cia yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm ceev thiab cov khoom tsim nyog.
