Umsebenzi we-cellulose ether oliminayo

I-Cellulose EtherUkugcinwa kwamanzi

Ukugcinwa kwamanzi kodaka kubhekiselwa emandleni odaka ukubamba nokukhiya amanzi. Ukuphakama kwe-viscosity ye-cellulose ether, kungcono ukugcinwa kwamanzi. Ngenxa yokuthi isakhiwo se-cellulose liqukethe i-hydroxyl ne-ether kanye ne-etherxyl kanye ne-ether

I-Solubity yeI-Cellulose Ether

1. I-coarser cellulose ether kulula ukuyisabalalisa emanzini ngaphandle kokuqothuka, kepha izinga lokuchithwa lihamba kancane. I-Cellulose Ether ngezansi kwe-60 Mesh ichithwa emanzini cishe imizuzu engama-60.

2. Izinhlayiya ezinhle ze-cellulose ether emanzini kulula ukuyisabalalisa hhayi ukusabalalisa hhayi okungokwemvelo, futhi izinga lokuchithwa lilinganiselwe. I-Cellulose ether ngaphezulu kwama-mesh ayincibilikisiwe emanzini cishe imizuzu emi-3.

3. I-Ultrafine Cellulose Ether isabalalisa ngokushesha emanzini, inciphise ngokushesha futhi yakha ukubonwa okusheshayo. I-Cellulose Ether ngenhla kwe-120 mesh ichithwa emanzini cishe amasekhondi angu-10-30.

Inhlanganisela ye-cellulose ether, okungcono ukugcinwa kwamanzi, izinhlayiya zama-coarse of cellulose ether kanye nendawo yokuxhumana yamanzi zincibilikile futhi zakha genomenon. I-glue isonge izinto ukuvikela ama-molecule amanzi ukuthi aqhubeke ukungena. Kwesinye isikhathi, noma ngabe kushukunyiswa isikhathi eside, ikhambi alikwazi ukuhlakazeka futhi lichithwe, lakha isisombululo esinodaka noma i-agglomerate. Izinhlayiya ezinhle zihlakazeka futhi zincibilike ngokushesha lapho zithintana namanzi ukwakha i-viscosity efanayo.

Ivelu ye-ph ye-cellulose ether (ukubambezeleka okubambezelekile noma amandla kusenesikhathi)

Inani le-PH ye-Cellulose Ether Alecres ekhaya nakwamanye amazwe lilawulwa ngokuyisisekelo cishe nge-7, elinama-acidic. Ngoba kusenenqwaba ye-glucose ye-glucose ye-glucose ekhishini ye-molecular ye-cellulose ether, indandatho ye-glucose enamanzi yiqembu eliyinhloko elibangela ukubambezeleka kosimende. Indandatho ye-glucose emzimbeni ingenza i-calcium ion kwikhambi le-yment hydration lekha amakhompiyutha e-calcium hydration, vimba ukwakheka kwe-calcium hydration isikhathi, ukuvikela ukwakheka kwe-calcium hydroxide kanye ne-calcium calcium hydroxide kanye ne-calcium calksstal, ngaleyo ndlela kubambezele inqubo ye-hydration. Uma inani le-PH liba ngumbuso we-alkaline, udaka luzovela isimo sokuqina kusenesikhathi. Manje iningi lamafektri okuguqula inani le-PH lisebenzisa i-sodium carbonate, i-sodium carbonate uhlobo lokusheshisa inhlazi, ukuthuthukisa ubumbano phakathi kwezinhlayiyana, i-calcium ion complely kanye ne-calcium ion complely kanye ne-calcium ion complely ngokushesha, kushukumise ngokushesha ukwakheka kwe-ettringite, ukuvuselelwa kosimende ngokushesha. Ngakho-ke, inani le-PH kufanele lishintshwe ngokuya ngamakhasimende ahlukile kwinqubo yangempela yokukhiqiza.

I-Cellulose ether ger

Umoya ongenziwa ngomoya we-cellulose ether ikakhulukazi ngoba i-cellulose ether ibuye ibe yi-surviperant, umsebenzi we-cellulose ether ikakhulukazi ebonakalayo esibonakalayo ephethwe yigesi, okuqala ukwethulwa kwama-bubble, kulandelwa. I-Celsulose Ether iqukethe i-ALKYL Group, inciphisa kakhulu ukungezwani komhlaba kanye namandla okuhlangana kwamanzi, isixazululo samanzi kwinqubo yokuyaluza kulula ukukhiqiza ama-bubble amaningi amancane avaliwe.

I-gelation of cellulose ether

I-Cellulose Ether incibilika ngodaka ngenxa yeqoqo layo lamangqamuzana we-methoxy ne-hydroxypropyl e-calcium ion kanye ne-aluminium eon ekwakhekeni kwe-gel ye-visuas, kuthuthukisa ubungako bodaka, baphinde baqinise ukugcwaliswa okuguqukayo nokuqiniswa okuguqukayo. Kodwa-ke, lapho i-matrix eyinhlanganisela icindezelwa, i-polymer ayikwazi ukudlala ukwesekwa okuqinile, ngakho-ke amandla nokulinganiswa kokuncipha kokuncipha kodaka.

Ukwakhiwa kwamafilimu we-cellulose ether

Kwakhiwa ifilimu elincanyana le-latex phakathi kwe-cellulose ether kanye nezinhlayiya zosekhukhwini ngemuva kwe-hydration. Ifilimu linokuthambisa uphawu futhi lithuthukisa into esomile yodaka. Ngoba i-cellulose ether inokugcinwa kwamanzi okuhle, gcina ama-molecule wamanzi anele angaphakathi kodaka, ngasikhathi sinye athuthukise ukunamathela kodaka, ngasikhathi sinye athuthukise amandla amahle kasimende, udaka lunepulasitiki enhle, anciphise i-forting contration deform.
