Acetate cab yog cov khoom fiber ntau ua rau ntawm cov lim dej cellulose, feem ntau yog siv nyob rau hauv kev tsim cov tshuab luam ntawv, thiab tseem siv tau rau hauv textiles, kev hnav khaub ncaws kho mob thiab lwm daim teb. Nws muaj kev ua tiav zoo, tsis yog-toxic, ib puag ncig phooj ywg, thiab biodegradable.
Nta
Kev txiav tawm siab ua tau zoo: tuaj yeem cuam tshuam kev phom sij xws li tar thiab nicotine, txhim kho kev nyab xeeb ntawm kev haus luam yeeb.
01
Zoo thermal stability: haum rau high-ceev luam yeeb cov khoom siv ntau lawm.
02
Cov kab mob tsis muaj tshuaj lom thiab tsw: ntsib cov qauv kev nyab xeeb thiab tsis muaj teeb meem rau tib neeg lub cev.
03
Kev tsis muaj peev xwm: piv nrog cov khoom siv hluavtaws, acetate fibers yog qhov yooj yim dua degraded ib txwm thiab yog ntau ib puag ncig phooj ywg.
04
Uniform phuam qauv: sawv daws lim ruaj khov thiab uniform kos tawm tsam
05
Cov txheej txheem ntau lawm
Raw Khoom Npaj
Lub ntsiab raw khoom:
Ntoo pulp: kev ua kom huv-purity -cellulose (ntau dua lossis sib npaug ntawm 95%)
Acetic anhydride: siv rau cov tshuaj tiv thaiv zoo
Glacial acetic acid: kuab tshuaj
Sulfuric acid (catalyst)
Triacetin: Coolizer (siv los txhim kho qhov yooj ntawm txoj phuam)
01
Acetylation cov tshuaj tiv thaiv
Ntoo pulp + glacial acetic acid → pretreatment (ua kom muaj kev ua kom muaj cellulose)
Ntxiv Acetic anhydride + sulfuric acid (catalyst), hnov mob ntawm 15 ~ 25 degree los tsim cellulose acetate
Cov kev sib npaug:
02
Kev Ua Ib nrab Hydrolym
Tswj cov degree ntawm hydrolysis thiab kho cov ntsiab lus acetyl (feem ntau 52% ~ 55%, piv txwv li cellulose diacetate)
Tom qab hydrolysis, cov khoom yog yaj nyob rau hauv acetone los ua ib qho kev daws teeb meem spining (dope)
03
Qhuav spinning spinning kev daws teeb meem → Red impurities
Spinneret extrusion → sau cov lus ntim (y-puab lossis zigzag hla ntu)
Cov Huab Cua Kub (70 ~ 100 Qib) Kom Qhuav → Acetone Volatilization, Fiber Social
Bundling → Daim Ntawv Nruag Nrawm Cov Lus Qhia
04
Cov ntawv thov MAIN
Lub tuam txhab ua kev txheeb xyuas kev sib tw kev sib tw kom paub tseeb tias nws qhov ua tau zoo thiab tsis muaj zog piv rau nws cov kev sib tw.
Cov Ntxaij lim lim lim dej (tseem ceeb siv, suav rau ntau dua 90% ntawm kev ua lag luam thoob ntiaj teb)
01
Kev hnav khaub ncaws kev kho mob (xws li daim ntaub thiab ntaub qhwv, vim tias lawv ua pa)
02
Textile kev lag luam (qee qhov kawg ntawm cov ntaub sib xyaw ua ke)
03
Muaj lim cov ntaub ntawv (xws li cua thiab ua kua pom)
04
Ntim thiab Ntim Khoom
TIM: Feem ntau qhwv hauv cartons lossis PE zaj duab xis, txog 200-250 kg ib pob.
🌡 Cov Kev Cog Lus Cia: Nws raug nquahu kom muab cia rau hauv qhov chaw txias thiab qhuav, zam kev kub thiab av noo.
