Kodi Hydrohthyl ali bwanji cellulose?

Hydroxyethyl cellulosendi cellulose yofunika kwambiri. Chifukwa cha zabwino za zojambula zopangira zida zowonjezera, zokonzanso, zopanda pake, zopanda mphamvu, komanso zokolola zazikulu, kafukufuku wake adakopa chidwi. . Mtengo wa Viscmson ndi mndandanda wofunikira kwambiri wa magwiridwe antchito a hydroxyethyl cellulose. Mu pepala ili, hydroxethyl cellulose yokhala ndi mtengo wa ma viscm pamwamba 5 × 105% ndi phulusa lochepera 0,3% adakonzedwa ndi njira yamadzimadzi kudzera munjira ziwiri.

Njira yolumikizira ndi njira yokonzekera alkali cellulose. Mu pepala ili, njira ziwiri zolumikizira zimagwiritsidwa ntchito. Njira yoyamba ndikugwiritsa ntchito acetone ngati wawuma. Cellulose yophika imadziwika mwachindunji mu ndende inayami ya sodium hydroide. Pambuyo poti zigawo zikachitika, wothandizila amawonjezeredwa kuti akwaniritse mwachindunji. Njira yachiwiri ndikuti zopangira cellulose zimayatsidwa mu madzi am'madzi a sodium hydroxide ndi urea, ndipo ma cellulose amakonzedwa ndi njirayi ayenera kufinya kuti achotse yuzele. Ma celluluse cellulose okonzedwa ndi njira zosiyanasiyana adasanthuliridwa ndi infrared spectropy ndi ray osiyanasiyana. Malinga ndi zomwe zapangidwa zomwe zakonzedwa ndi kukwaniritsidwa, njira yosankhidwa imatsimikizidwa.

Kuti mudziwe njira yabwino kwambiri yoyeserera, yomwe imagwira ntchito yamankhwala a antioxidant, Lyonde ndi Glaic Actic Acid mu chikondwerero chidasanthula poyamba. Kenako yambitsani pulogalamu yoyesera yoyesa yoyesera, kudziwa zinthu zomwe zimakhudza kwambiri magwiridwe antchito a hydroxethyl cellulose, ndikugwiritsa ntchito mafayilo a 2% a chelo. Zotsatira zoyesera zikuwonetsa kuti zinthu monga kusankhidwa, kuchuluka kwa ma ethylene oxide kuwonjezeredwa, nthawi ya ma alyal, kutentha ndi nthawi yachiwiriyi malonda. Kuyesa kwa Orthogoner ndi zinthu zisanu ndi ziwiri ndipo magawo atatu adakokedwa, ndipo zomwe zimakupangitsani kukopeka ndi zotsatira zoyeserazo zitha kusanthula zinthu zazikuluzikulu komanso zomwe zimakuthandizani. Pofuna kukonzekera zinthu zomwe zili ndi zikhalidwe zapamwamba za ma vistecmuti zopangidwa, ndipo njira yabwino yokonzekera hydrothyl cellulose idatsimikizika chifukwa choyesera.

Katundu wa okwera kwambirihydroxyethyl celluloseadayesedwa ndikuyesedwa, kuphatikizapo kutsimikiza kwa mafakisoni, phulusa, chinyezi, kusinthidwa kwa ma chromar, njira zina zamagetsi zomwe zimagwiritsidwa ntchito Kuti mufufuze ndikuwonetsa kapangidwe kazinthu, joifanganefictionation, molar increemile, crystall, kukhazikika kwa matenthedwe, ndi zina zoyeserera.

Hydroxyethyl cellulose, cellulose yofunika kwambiri yochokera ku zinthu zomwe zili zochulukirapo, zokonzanso, zosasintha, Nontobic, zopatsa mphamvu. Makulidwe a hydroxethyl cellulose ndi chizindikiro chofunikira kwambiri cha ntchito yake. Makutu a hydroxethyl cellulose ndi pamwamba pa 5 × 104Msa z × 104Msa z × 104MPA, ndipo phulusa ndi lochepera 0,3%.

Mu pepala ili, mafayilo apamwamba a hydroxethyl cellulose adakonzedwa ndi njira yamadzimadzi ya gawo kudzera mu ma alkirization ndi kuyerekeza. Njira yolumikizira ndi kukonzekera alkali cellouse. Sankhani njira ziwiri zokwanira. Chimodzi mwazinthu zomwe zimapangidwa ndi cellulose ndizosagwirizana mwachindunji ndi acetone monga wofooketsa mu yankho la sodium hydroous hydroide, kenako ndikuwonetsa kuti ndi wothandiziritsa ndi wothandizila. Wina ndikuti ma cellulosic amayatsidwa mu mankhwala a sodium hydroxide ndi urea. Thelkali cellulose imayenera kuchotsedwa zisanachitike. Mu pepala ili, ma celloses osiyanasiyana a Alkali amaphunziridwa ndi infrared spectropy ndi ray osiyanasiyana. Pomaliza, njira yachiwiri imakhazikitsidwa molingana ndi katundu wa zopangidwa.

Pofuna kudziwa kukonzekera njira zakuthupi, zomwe zimachitika magwiridwe a antioxidant, alkali ndi glait acetic acid podya idaphunzitsidwa. Zinthu zomwe zikukhudza kukonzekera kwa hydroxethyl cellulose zidatsimikizika ndi kuyesa kwa chinthu chimodzi. Kutengera phindu la ma viscc a malonda mu 2% soluous yankho. Zotsatira zoyesera zikuwonetsa kuti voliyumu ya akuru, kuchuluka kwa Ethylene oxide, nthawi ya ma alyal, kutentha ndi nthawi yanthawi yoyamba komanso yachiwiri imakhala ndi mphamvu yochita malonda. Njira ya zinthu zisanu ndi ziwiri ndipo magawo atatu adakhazikitsidwa kuti adziwe njira yabwino yokonzekera.

Timasanthula katundu wakonzedwahydroxyethyl cellulose, kuphatikizapo mafakisoni, phulusa, chinyezi, ndi zina mwamphamvu, kukhazikika kwa magilekiti Njira zoyesera adatengera miyeso ya Asso.
