Kev sib xyaw thiab siv cov ntawv lim

Kev sib xyaw thiab siv cov ntawv lim
1, Kev sib xyaw ntawm cov ntawv lim
Filter paper yog ib hom ntawv lim nruab nrab uas muaj cellulose, hemicellulose, thiab inorganic tshuaj. Nws cov khoom tseem ceeb yog cellulose, uas feem ntau tau los ntawm cov nroj tsuag. Cov ntaub ntawv raw rau kev tsim cov ntawv lim feem ntau muaj xws li ntoo pulp, spruce pulp, thiab xibtes fiber, ntawm cov ntawv lim ua los ntawm cov ntoo pulp muaj qhov zoo tshaj plaws thiab tus nqi kim tshaj plaws.
2, Hom ntawv lim
Cov ntawv lim tuaj yeem muab faib ua qib sib txawv, qhov ntau thiab tsawg, cov duab, thiab qhov pore loj raws li cov khoom siv sib txawv, cov txheej txheem tsim khoom, thiab cov khoom siv. Cov ntaub ntawv lim dej hauv khw feem ntau tuaj yeem muab faib ua pawg hauv qab no:
1. Ordinary filter paper: haum rau kev kuaj pom dav dav. Feem ntau muab faib raws li qhov tsis xws li aperture loj, ntawv zoo, xim, thiab thickness.
2. Microporous lim ntawv: Nrog rau qhov pore me me, nws tuaj yeem lim tawm cov khoom me me, kab mob, thiab kab mob. Feem ntau yog siv nyob rau hauv high-end kuaj thwmsim thiab chaw kws tshuaj.
3. Gas lim ntawv: siv rau lim roj xws li aerosols.
4. Cov ntawv lim dej zoo: Haum rau kev kuaj dej zoo thiab kev kho dej, nws tuaj yeem lim tawm cov impurities hauv dej.
5. Cov ntawv lim tshwj xeeb: suav nrog cov ntawv lim dej kub, cov ntawv lim dej tsis muaj protein tsawg, cov qaub ncaug cais cais, thiab lwm yam.
3, Lub hom phiaj ntawm cov ntawv lim
Cov ntawv lim dej yog cov khoom siv tseem ceeb hauv kev sim dav siv hauv chaw soj nstuam, kev lag luam, kev tsim tshuaj, biotechnology, kev tiv thaiv ib puag ncig, kev ua zaub mov, thiab lwm yam. Cov kev siv tseem ceeb muaj xws li:
1. Siv rau kev kuaj pom thiab kev sib cais ntawm cov khoom.
2. Siv hauv kev lag luam xws li kev tsim tshuaj thiab kev ua zaub mov.
3. Siv rau kev npaj cov khoom siv lim xws li daim nyias nyias thiab lim cartridges.
4. Siv rau purifying thiab kho dej zoo.
5. Siv rau kev tiv thaiv ib puag ncig, xws li kev tswj xyuas dej, huab cua pom, thiab lwm yam.
Hauv cov ntsiab lus, lim ntawv, raws li cov khoom siv lim dej siv tau zoo, muaj ntau yam kev siv hauv kev tsim khoom, kuaj, thiab kev lag luam. Xaiv cov ntawv lim tsim nyog yog qhov tseem ceeb tshwj xeeb los xyuas kom meej qhov tseeb thiab kev nyab xeeb ntawm qhov kev sim.
