Cellulose acetate chinhu chakasiyana-siyana chine huwandu hwakawanda hwekushandisa. Muindasitiri yefodya, cellulose acetate tow ndiyo yekutanga mbishi yemasefa efodya nekuda kwekuita kwayo kusefa. Inoshandiswawo muindasitiri yemafirimu nemapurasitiki kugadzira mafirimu emifananidzo, mafiramu ezviratidziro, uye zvibatiso zvemidziyo. Uye zvakare, cellulose acetate inoshanda sechinhu chakakosha chemembrane, kusanganisira kusefa membrane uye reverse osmosis zvinhu, nekuda kwekunaka kwayo kupenya uye kusarudza. Iine biodegradability uye kuchinjika, cellulose acetate inoramba ichiita basa rakakosha mune zvese zvechinyakare kugadzira uye zvemazuva ano mashandisirwo ezvakatipoteredza.
Cellulose Acetate Filtration Process
1. Raw Material Kugadzirira & Acetylation
Maitiro anotanga nehuni pulpcellulose, iyo inonatswa kubvisa lignin, hemicellulose, uye mamwe matsvina. Iyo yakacheneswa cellulose inozoitwa nayoacetic acid, acetic anhydride, uye acatalystkugadzira cellulose acetate esters. Nekudzora dhigirii rekutsiva, mamakisi akasiyana senge diacetate kana triacetate anogona kuwanikwa.
2. Kuchenesa & Spinning Solution Kugadzirira
Mushure meacetylation, musanganiswa wekuita haugadziriswi, uye zvigadzirwa zvinobviswa. Iyo cellulose acetate inoshambidzwa, yakaomeswa, uye inonyungudika mukatiacetone kana acetone-mvura musanganiswakugadzira homogeneous spinning solution. Panguva ino, mhinduro inopindakusefakubvisa zvisingasviki zvimedu uye gels, kuve nechokwadi chekuenderana uye kugadzikana.
3. Fiber Formation & Finishing
Iyo yekutenderera mhinduro inogadziriswa uchishandisa iyoyakaoma kuruka nzira, iyo inobudiswa kuburikidza ne spinnerets uye yakasimbiswa kuva filaments sezvo solvent inoputika. Iyo filaments inounganidzwa, yakatambanudzwa, uye inoumbwa kuita tambo inopfuurira kana shinda. Mishonga yepashure senge kutambanudza, kucheka, kana kupedzisa kunoiswa kuwedzera fiber zvivakwa, zvichiita kuti ive yakakodzera kunyorera mu.mudzangafilters, machira, uye faibha dzemhando yepamusoro.

Mhedziso
Cellulose acetate chinhu chakakosha chinoshandiswa mumasefa, mafirimu, mapurasitiki, uye membranes, inokosheswa nekuita kwayo uye biodegradability. Panguva yekugadzira, kusefa kunoshanda kwakakosha kuti uve nechokwadi chekuchena uye kuenderana.
