Cellulose Ethers kuchokera ku Kima Chemical Co., Ltd

Ma cellulose ethersndi ma polima osungunuka m'madzi opangidwa kuchokera ku cellulose, ma polima ochuluka kwambiri m'chilengedwe. Kwa zaka zopitilira 60, zinthu zosunthikazi zakhala zikugwira ntchito zambiri, kuyambira pazomangamanga, zoumba ndi utoto mpaka zakudya, zodzoladzola ndi mankhwala.
Pazomangamanga, ma cellulose ethers amakhala ngati zokhuthala, zomangira, zopangira mafilimu komanso zosunga madzi. Zimagwiranso ntchito ngati zothandizira kuyimitsidwa, zowonjezera, zothira mafuta, zoteteza ma colloids ndi ma emulsifers. Kuphatikiza apo, mayankho amadzi amtundu wina wa cellulose ethers thermally gel, chinthu chapadera chomwe chimagwira ntchito yofunika kwambiri modabwitsa.
zosiyanasiyana ntchito. Kuphatikiza kwamtengo wapatali kumeneku sikupezeka mu polima ina iliyonse yosungunuka m'madzi.
Mfundo yakuti zinthu zambiri zothandiza zimakhalapo nthawi imodzi ndipo nthawi zambiri zimakhala zosakanikirana zingakhale zothandiza kwambiri pazachuma. M'zinthu zambiri, zosakaniza ziwiri, zitatu kapena kupitilirapo zimafunika kuti zigwire ntchito yofanana ndi chinthu chimodzi cha cellulose ether. Kuphatikiza apo, ma cellulose ethers ndi othandiza kwambiri, nthawi zambiri
kutulutsa magwiridwe antchito amtundu wocheperako kuposa momwe amafunikira ma polima ena osungunuka m'madzi.
Dow Construction Chemicals imapereka zinthu zingapo zama cellulosic, kuphatikiza methyl cellulose, hydroxyethyl cellulose ndi carboxymethyl cellulose. Ma methyl cellulose ethers amagwiritsidwa ntchito kwambiri pazinthu zambiri zomanga ndi zomangamanga.

Chemistry of Cellulose Ethers

Bizinesi yathu imapereka ma cellulose ethers m'mitundu inayi:
1. Hydroxyethyl methyl cellulose (HEMC/MHEC)
2.Hydroxypropyl methyl cellulose (HPMC,MC)

3. Hydroxyethyl cellulose (HEC)

4.Carboxy methyl cellulose(CMC)
Mitundu yonse iwiriyi ili ndi polymeric msana wa cellulose, chakudya chachilengedwe chomwe chimakhala ndi mayunitsi a anhydroglucose. Panthawi yopanga ma cellulose ethers, ulusi wa cellulose umatenthedwa ndi njira ya caustic yomwe imathandizidwa ndi methyl chloride, komanso propylene oxide kapena ethylene oxide, yopereka hydroxypropyl methyl cellulose kapena hydroxyethyl methyl cellulose, motero. Chopangidwa ndi fibrous reaction chimayeretsedwa ndikusinthidwa kukhala ufa wabwino, wofanana.
Zogulitsa zapadera zapangidwanso kuti zikwaniritse zofunikira zamakampani a specifc.
Zogulitsa zathu za cellulose ether zimapezeka m'mitundu itatu: ufa, ufa wothira pamwamba ndi granular. Mtundu wa chinthu chomwe chikupangidwa chimakhudza momwe mungasankhire. Muzosakaniza zouma zouma, ufa wosagwiritsidwa ntchito nthawi zambiri umagwiritsidwa ntchito, pamene okonzeka kusakaniza, momwe ufa wa cellulosic umawonjezeredwa mwachindunji kumadzi, ufa wothira pamwamba kapena mawonekedwe a granular amakonda.

General Properties

Katundu wamba wa ma cellulose ethers alembedwa apa. Zogulitsa zapayekha zimawonetsa izi mosiyanasiyana ndipo zitha kukhala nazo
additional properties desirable for specific applications. For more information, email at sales@kimachemical.com .
