Acetate fabrics yog ua nrog spun filaments ntawm cellulose muab los ntawm ntoo pulp. Muab faib ua cov tshuaj fiber ntau textile lossis semi-synthetic, acetate yog qee zaum sib xyaw nrog cov ntaub plaub, ntaub plaub lossis paj rwb kom nws muaj zog. Acetate flakes yog tsim los ntawm cov tshuaj tiv thaiv ntawm cov ntoo pulp rau ntau yam acetic acids.
Tsuas yog li ntawd, qhov twg acetate tsim?
3. Ntau lawm Txheej txheem ntawm Acetate Fiber ntau. Acetate fiber yog tsim tawm los ntawm reacting siab purity ntoo pulp nrog acetic anhydride. Cov acetate flakes uas yog tsim tawm los ntawm cov tshuaj tiv thaiv no yog yaj nyob rau hauv ib qho hnyav, lim, thiab hloov kho kom tau txais cov tshuaj spinning.
Puas yog acetate Cov ntaub zoo? Npuag ua los ntawm acetate muab ib theem siab ntawm kev nplij siab rau cov neeg hnav. Nws yog qhov tshwj xeeb tshaj yog siv acetate ntaub rau hauv ob sab phlu as acetate muaj cov khoom zoo dua noo noo nqus, piv rau lwm cov hluavtaws fibers.
Ib yam li ib tug yuav nug, puas yog acetate ntuj lossis hluavtaws?
Ntuj fibers suav nrog paj rwb , fur, wool, etc. Regenerated fibers yog cov khoom siv ntuj tsim uas tau ua tiav rau hauv cov qauv fiber ntau. Regenerated fibers xws li cellulose thiab ntoo pulp yog siv los ua cov ntaub ntawv xws li rayon thiab acetate. Synthetic fibers yog cov txiv neej ua los ntawm cov tshuaj.
Puas yog acetate teeb meem rau tib neeg?
Ethyl acetate yog heev flammable, thiab tshuaj lom thaum noj los yog nqus tau, thiab cov tshuaj no tuaj yeem ua rau cov kab mob hauv nruab nrog cev thaum rov tshwm sim los yog ntev dua. Ethyl acetate kuj tuaj yeem ua rau khaus thaum nws los ntawm qhov muag lossis tawv nqaij.
