Cellulose acetate yog ntau yam khoom siv nrog ntau yam kev siv. Hauv kev lag luam luam yeeb, cellulose acetate cab yog cov khoom siv tseem ceeb rau cov lim luam yeeb vim nws qhov kev pom zoo heev. Nws kuj tseem siv rau hauv kev lag luam zaj duab xis thiab plastics rau kev tsim cov duab thaij duab, cov duab thaij duab, thiab cov cuab yeej ua haujlwm. Tsis tas li ntawd, cellulose acetate yog cov khoom siv tseem ceeb rau daim nyias nyias, nrog rau cov ntaub so ntswg thiab rov qab osmosis cov ntsiab lus, ua tsaug rau nws cov permeability zoo thiab kev xaiv. Nrog nws cov biodegradability thiab adaptability, cellulose acetate tseem ua lub luag haujlwm tseem ceeb hauv ob qho tib si kev tsim khoom thiab kev siv ib puag ncig niaj hnub.
Cellulose Acetate Filtration Txheej txheem
1. Raw Material Preparation & Acetylation
Cov txheej txheem pib nrogntoo pulpcellulose, uas yog purified kom tshem tawm lignin, hemicellulose, thiab lwm yam impurities. Lub purified cellulose yog ces reacted nrogacetic acid, acetic anhydride, thiab acatalystlos tsim cellulose acetate esters. Los ntawm kev tswj cov qib kev hloov pauv, cov qib sib txawv xws li diacetate lossis triacetate tuaj yeem tau.
2. Purification & Spinning Solution Npaj
Tom qab acetylation, cov tshuaj tiv thaiv sib tov yog neutralized, thiab cov khoom lag luam raug tshem tawm. Cov cellulose acetate yog ntxuav, qhuav, thiab yaj hauvacetone los yog acetone - dej sib tovlos tsim ib homogeneous spinning tov. Nyob rau theem no, kev daws teeb meemlimtxhawm rau tshem tawm cov khoom tsis zoo thiab cov gels, ua kom muaj kev sib luag thiab ruaj khov.
3. Fiber tsim & tiav
Cov tshuaj spinning yog ua tiav siv covqhuav spinning txoj kev, qhov twg nws yog extruded los ntawm spinnerets thiab solidified rau hauv filaments raws li cov kuab tshuaj evaporates. Cov filaments yog sau, ncab, thiab tsim rau hauv nruam cab los yog xov paj. Tom qab kev kho mob xws li ncab, crimping, los yog tiav yog siv los txhim kho cov khoom fiber ntau, ua rau lawv tsim nyog rau kev siv hauvluam yeeblim, textiles, thiab tshwj xeeb fibers.
Great Wall Filtration Filter Paper
SCY Series lim ntawv
Cov ntawv lim no, nrog nws cov cellulose thiab cationic resin muaj pes tsawg leeg, tshwj xeeb tshaj yog zoo rau lim cellulose acetate daws. Nws muab cov neeg kho tshuab siab zog, ruaj khov porosity, thiab txhim khu kev qha kev tshem tawm cov kab mob. Cov ntsiab lus ntawm polyamide epoxy resin tsawg (<1.5%) ua kom muaj kev sib raug zoo thiab kev nyab xeeb hauv kev ua haujlwm ntawm cellulose acetate, pab tshem tawm cov khoom zoo, gels, thiab insoluble impurities thaum tswj kev ruaj ntseg tshuaj thiab ua raws li cov qauv kev nyab xeeb ntawm cov khoom noj thiab tshuaj.
Qhov zoo
High Filtration Efficiency- Tshem tawm cov khoom zoo, gels, thiab insoluble impurities los ntawm cellulose acetate daws.
Muaj zog Mechanical Strength- Lub zog tawg ≥200 kPa ua kom ruaj khov thiab ua haujlwm ruaj khov nyob rau hauv siab.
Zoo ib yamPorosity- Tswj huab cua permeability (25–35 L / ㎡·s) muab cov nqi txaus ntseeg tau thiab cov txiaj ntsig pom tsis sib xws.
Xaus
Cellulose acetate yog cov khoom siv tseem ceeb siv hauv lim, films, plastics, thiab daim nyias nyias, muaj nuj nqis rau nws cov kev ua tau zoo thiab biodegradability. Thaum lub sij hawm tsim khoom, kev pom zoo yog qhov tseem ceeb los xyuas kom meej purity thiab sib xws.
Great phab ntsaSCY Serieslimntawvmuab cov txiaj ntsig zoo nrogsiab pom efficiency, muaj zog durability, thiab ruaj khov porosity. Nrog cov ntsiab lus qis rau kev sib raug zoo zoo, nws yog qhov kev xaiv txhim khu kev qha rau kev ua cov cellulose acetate hauv cov zaub mov, tshuaj, thiab tshuaj lom neeg kev lag luam.
