Cellulose acetate cab 9004-35-7

Cellulose cab yog tshuaj lom neeg ua los ntawm cov ntaub ntawv ntuj thiab feem ntau siv hauv cov ntawv thov xws li cov ntxaij lim dej.

Cellulose acetate cab tsim kho

Cov txheej txheem tsim khoom yog raws li hauv qab no:

1. PretReatment

Cellulose nyoos yog crushed thiab bleached.

Kom qhuav yog ua rau cov ntsiab lus ya raws ntawm<5%.

2. Acetylation

Cellulose, acetic anhydride, thiab catalyst (sulfuric acid) tau ntxiv rau ib tug reactor.

Tswj qhov kub ntawm 20-40℃thiab cia cov tshuaj tiv thaiv mus rau 2-4 teev.

Tsim cellulose triacetate (Ds ≈ 3).

3. Ib nrab Hydrolysis

Ntxiv dej rau tswj hydrolysis.

Hloov cellulose triacetate rau cellulose diacetate (DS ≈ 2.4).

Cov kauj ruam no txiav txim rau cov solubility thiab ua cov khoom ntawm cov khoom kawg.

4. Nag lossis daus thiab huv

Cov khoom siv tshuaj tiv thaiv yog hliv rau hauv dej rau nag lossis daus.

Rov ua dua cov dej ntxuav tau ua kom tshem tawm residual acid thiab catalyst.

Centrifugal lub cev qhuav dej yog ua kom tau txais cellulose acetate flakes.

5. Kom Qhuav

Cov cua kub kom qhuav<3% moisture

Ua cellulose flakes

6. Kev npaj ntawm spinning daws

Dispve cellulose acetate flakes nyob rau hauv acetone

Npaj ib 20-25% spinning daws

Lim thiab DEGAS

7. Qhuav spinning

Extrududude Vauv cov tshuaj spinning los ntawm spinneret

Volatilize cov kuab tshuaj nyob rau hauv cov huab cua kub (80-120 degree)

Daim ntawv txuas ntxiv monourfilaments (kwv yees li 20-40 μm hauv lub taub)

8. Caj kev tsim qauv

Pob Zeb Ntau MONOFILAMENTS

Thov kev ua txhaum cai (10-15 tus plig ib nti)

Txiav rau ib qho ntev ntev (feem ntau 6-8 hli)

9. Tom qab ua

Kev kho roj (txhawm rau txhim kho cov khoom lag luam)

Kom qhuav thiab txhuam

Ntim ntawm cov khoom tiav

Txhawm rau kom muaj kev nyab xeeb ntawm koj cov khoom, ib puag ncig ua phooj ywg, yooj yim yuav muab tau yooj yim rau.

1. Cov lim dej luam yeeb (siv thawj zaug)

>90% Kev Lag Luam Thoob Ntiaj Teb

Siv tau TAR / NICOTINE Foltration

Ntsuas Huab Cua Tsis kam

2. Cov ntawv nyeem & tsis muaj

Kev Kho Mob Cov Ntaub: Kev phais mob ntsej muag, khaub ncaws hnav

Hwm textiles: Xyaw nrog cov paj rwb / polyester

3. Kev lag luam lim

Dej / Huab Cua Purification

HVAC cov ntxaij lim dej

4. Biomedical

Cov Kws Nqa Khoom Noj Khoom Haus

Biodegradable Cov Khoom Kho Mob

5. Lwm cov kev siv

Cov tshuaj pleev ib ce (pleev xim tso tawm cov ntaub qhwv)

Lub Tshuab Luam Ntawv 3D luam ntawv (hloov kho)

Cov ntsiab lus tseem ceeb:
✔ Cov cellulose ntuj-raws li
Plyog kho qhov porosity
✔ Zoo dua biodegrentably dua li hluavtaws fibers
