2. Properties na ether
Properties na Celling Zevers ya dogara da:
Matsayi na Polymerization DP Yawan raka'un Glucose-danko
M da kuma digiri na sauya, digiri na daidaituwa na canji - tantance filin aikace-aikacen
Girman barbashi - Sultility
Jiyya na farfajiya (watau jinkirin rushewa) - Lokacin danko yana da alaƙa da ƙimar tsarin
Digiri na gyare-gyare - inganta juriya da kuma aiki na ether.
3. Matsayin ether - riƙewar ruwa
Elerlulose ether wani yanki ne na polymer wanda aka haɗa da raka'a β-dlucise. Groupungiyar Hydroxyl a cikin kwayoyin da oxygen atom a kan ethon bunƙasa samar da haɗin hoda a saman sarkar polymer da kuma entanglesan kwayoyin. A cikin sarkar, yana jinkirta fitar da ruwa kuma yana tunawa da ginin tushe.

4. Matsayin ether - tasirin thickening
Elethulose eth eth ether zai iya ƙara haɗin kai tsakanin abubuwan da ke tattare da turmin Gypsum, wanda aka bayyana a cikin karuwar daidaito na turmi.
Manyan fa'idodin da aka bayar da ɓarkewar celululose na ELE:
Rage ash ash
Kara tasirin zuwa tushe
Rage sagging na turmi
ci gaba da turmi ko da
5. Matsayin ether - aikin ƙasa
Ellululous ETher ya ƙunshi ƙungiyoyi na Hydrophilic (Groungiyoyin Hydroxyl, Erher Bade) da kuma ƙungiyoyi na Hydrophobic (Methyl ƙungiyoyi, glucose zobba.
(Tsarin tashin hankali na ruwa shine 72wn / m, da ether ne HPC 42, HPMC 50, MC 56, CMC 79MN / M)
Manyan fa'idodin da aka bayar da yanayin samar da sel ELES:
Air-runtse sakamako (santsi scraping, low rigar da yawa, low m modulus, daskarewa-thaw juriya)
Wetting (yana ƙaruwa da adhesion don substrate)
6. Bukatar da ta yi wa plastering na Gypasum na Gypsum don Elthulose Erher
(1). Mai riƙe ruwa mai kyau
(2). Kyakkyawan aiki, babu cakina
(3). Batch scraping santsi
(4). Mai karfi anti-sagging
(5). Zazzabi na gel ya fi ƙarfe 75 ° C
(6). Yawan rushewa
(7). Zai fi kyau a sami ikon yin iska kuma yana iya dakatar da kumfa a cikin turmi
11. Yadda za a tantance sashi na ether
Don plastering plasters, wajibi ne don riƙe isasshen ruwa a cikin turbashin iska a cikin dogon lokaci domin yana da aiki mai kyau kuma don guje wa fasa jiki. A lokaci guda, eter eter yana riƙe da adadin da ya dace na ruwa na dogon lokaci don yin turmi yana da tsayayyen tsari.
Yawan ethulose ether ya dogara da:
Danko na sel eth
Tsarin samar da sinlululose
M abun ciki da rarraba celululose ether
Girman barbashi na rarrabe sel
Nau'in da kuma abun da ke tattare da turmi na gypsum
Rufancin ƙarfin sha na Layer Layer
Amfani da ruwa don daidaitaccen yaduwa na tururuwa na Gypsum
Saitin lokacin gypsum
Kaurin kai da aikin gini
Yanayin gini (kamar zafin jiki, saurin iska, da sauransu)
Hanyar gini (scraping na inji, inji na inji)
