I-Cellulose Ethers evela kwi-Kima Chemical Co., Ltd

I-cellulose ethersziipolima ezinyibilikayo emanzini eziphuma kwiselulosi, eyona polymer ininzi kwindalo.Ngaphezu kweminyaka engama-60, ezi mveliso zininzi zidlale indima ebalulekileyo kwizicelo ezininzi, ukusuka kwiimveliso zokwakha, iiseramikhi kunye neepeyinti ukuya kukutya, izinto zokuthambisa kunye namayeza.
Kwiimveliso zokwakha, i-cellulose ethers isebenza njengezinto ezityebisayo, izibophelelo, iifilim kunye neearhente zokugcina amanzi.Zikwasebenza njengezixhobo zokuxhoma, i-surfactants, i-lubricant, i-colloids ekhuselayo kunye ne-emulsifers.Ukongeza, izisombululo ezinamanzi ze-cellulose ethers gel thermally gel, ipropathi ekhethekileyo edlala indima ephambili kwinto emangalisayo.
ezahlukeneyo izicelo.Olu ludibaniso oluxabisekileyo lweepropati alufumaneki kuyo nayiphi na enye i-polymer enyibilikayo emanzini.
Inyani yokuba iipropathi ezininzi eziluncedo zikhoyo ngaxeshanye kwaye zihlala zisebenza ngokudityaniswa inokuba lulutho olubalulekileyo kwezoqoqosho.Kwiinkqubo ezininzi, izithako ezibini, ezithathu okanye ezingaphezulu ziyakufuneka ukwenza umsebenzi ofanayo owenziwe yimveliso ye-cellulose ether enye.Ukongeza, ii-cellulose ethers zisebenza kakhulu, rhoqo
ukunikezela ukusebenza ngokufanelekileyo kugxininiso oluphantsi kunolo lufunekayo kwezinye iipholima ezinyibilikayo emanzini.
Iikhemikhali zoKwakha iDow zibonelela ngoluhlu olubanzi lweemveliso ze-cellulosic, kubandakanya i-methyl cellulose, i-hydroxyethyl cellulose kunye ne-carboxymethyl cellulose.I-Methyl cellulose ethers isetyenziswa kakhulu kwizicelo ezininzi kwishishini lokwakha kunye nelokwakha.

Ikhemistry yeCellulose Ethers

Ishishini lethu libonelela nge-cellulose ethers kwiintlobo ezine ezisisiseko:
1.I-Hydroxyethyl methyl cellulose (HEMC/MHEC)
2.Hydroxypropyl methyl cellulose (HPMC,MC)

3.I-Hydroxyethyl cellulose (HEC)

4.Carboxy methyl cellulose(CMC)
Zombini ezi ntlobo zine-polymeric backbone ye-cellulose, i-carbohydrate yendalo equlethe ulwakhiwo olusisiseko oluphindaphindiweyo lweeyunithi ze-anhydroglucose.Ngexesha lokwenziwa kwe-cellulose ethers, iifiber ze-cellulose zifudunyezwa ngesisombululo se-caustic, emva koko, siphathwa nge-methyl chloride, kunye nokuba yi-propylene oxide okanye i-ethylene oxide, ivelisa i-hydroxypropyl methyl cellulose okanye i-hydroxyethyl methyl cellulose, ngokulandelanayo.Imveliso ye-fibrous reaction ihlanjululwe kwaye iphantsi ibe ngumgubo ococekileyo, ofanayo.
Iimveliso zodidi olukhethekileyo nazo ziye zayilwa ukuhlangabezana neemfuno zamashishini athile.
Iimveliso zethu ze-cellulose ether zifumaneka ngeendlela ezintathu ezahlukeneyo: umgubo, umgubo owenziwe phezulu kunye negranular.Uhlobo lwemveliso eyenziwayo luphembelela ukuba kukhethwe luphi uhlobo.Kwiinkqubo ezininzi zokuxuba okomileyo, i-powder engaphendulwanga isetyenziswa ngokuqhelekileyo, ngelixa ukulungelelaniswa kwezicelo, apho i-cellulosic powder yongezwa ngokuthe ngqo emanzini, i-powder-treated powder okanye iifom zegranular zikhethwa.

Iipropati ngokuBanzi
