Doorka dhoobada methyl cellulose sodium:
Waxaa si weyn loogu isticmaalaa warshadaha dhoobada, inta badan slurry glaze ee jirka dhoobada, dhoobada dhoobada glaze hoose iyo glaze dusha sare, daabacaadda glaze iyo seepage glaze.Ceramic class chitosan cellulose CMC waxaa inta badan loo isticmaalaa sida excipient, balaastik iyo wakiilka xoojinta ee jirka cagaaran dhoobada ah, kaas oo hagaajin kara xawaaraha jidhka cagaaran, ka hortagtaa alaabta la dhammeeyey in ay dillaacaan, iyo fududeeyo samaynta jidhka cagaaran;
Doorka darajada dhoobada chitosan cellulose CMC ee glaze slurry waa xidhe, wakiilka hakadka ah iyo wakiilka xinjirowga.Ku darida qadar ku habboon oo ah dhoobada methyl cellulose CMC waxay wanaajin kartaa waxtarka shiida, hagaajinta dareeraha glaze slurry, kordhinta xoogga glaze ceeriin, hoos u dhigidda qalajinta glaze, oo ka dhigi si adag oo lagu daro jidhka cagaarka ah iyada oo aan lahayn diirka ka baxaya;Viscosity ee methylcellulose CMC aqueous aqueous ayaa si aad ah hoos ugu dhacay heerkulka sii kordhaya.Viscosity of glaze slurry oo lagu daray antelope methyl cellulose CMC sidoo kale waxay isku beddeshaa heerkulka, markaa waa in fiiro gaar ah la siiyaa si loo ilaaliyo heerkulka dhalaalka ee aan aad u bedelin wax soo saarka.Intaa waxaa dheer, glaze slurry oo ay ku jiraan ceramik fasalka antelope methyl cellulose CMC waxay leedahay haynta biyaha, taas oo ka dhigaysa lakabka glaze si siman u qalalan, dusha sare ee glaze waa mid siman oo is haysta, dusha sare ee glaze ka dib markii la toogtay waa siman yahay oo siman, saameyntuna waa wanaagsan tahay.
Habka kala dirida ee darajada dhoobada methyl cellulose:
Heerka dhoobada methyl cellulose ayaa si toos ah loogu qasaa biyo si loo diyaariyo koollo la mid ah, waxayna diyaar u tahay isticmaalka.Marka la habeynayo koollada karboxymethylcelulose ee darajada dhoobada ah, marka hore ku dar qaddar gaar ah oo biyo nadiif ah haanta wax-karinta ee qalabka wax kicinaya, iyo marka aaladda wax-karinta la shido, si tartiib ah oo siman isku qas heerka dhoobada anthomethyl cellulose.Ku dhex daadi haanta wax lagu dubo oo sii walaaq, si heerka dhoobada methyl cellulose iyo biyuhu ay si buuxda isugu darsamaan, iyo darajada dhoobada antelope methyl cellulose si buuxda ayaa loo dhalaali karaa.Marka la kala diro methylcellulose-fasalka dhoobada, sababta ay tahay in si siman loo faafiyo oo si joogto ah loo walaaqo waa "in laga hortago dhacdooyinka agglomeration iyo caking marka methylcellulose-ceramic-grade methylcellulose uu la kulmo biyaha, iyo in la yareeyo dhacdooyinka methylcellulose-ceramic-grade.Dhibaatada kala dirida qadarka methyl cellulose", iyo hagaajinta xawaaraha kala dirida darajada dhoobada methyl cellulose.Wakhtiga wax walaaqaya la mid ma aha wakhtiga methylcellulose darajada dhoobada uu si buuxda u dhalaali karo.Waa laba fikradood.Guud ahaan, wakhtiga kicinta aad ayuu uga gaaban yahay wakhtiga loo baahan yahay in methylcellulose darajada dhoobada ay si buuxda u dhalaaliso.Inta jeer ee loo baahan yahay waxay ku xiran tahay xaaladda gaarka ah.
Saldhigga lagu go'aaminayo waqtiga walaaqdu waa: marka methylcellulose-ceramic-grade si isku mid ah loogu kala firdhiyo biyaha oo aysan jirin agglomerate weyn oo muuqda, karitaanka waa la joojin karaa, iyo methylcellulose-ceramic-grade iyo biyaha ayaa laga tagi karaa iyagoo taagan.Soo dhex gal oo isku milmaan.
Saldhigga lagu go'aaminayo wakhtiga loo baahan yahay dhalaalidda dhammaystiran ee darajada dhoobada antelope methylcellulose waa sida soo socota:
(1) Fasalka dhoobada karboxymethyl cellulose wuxuu si buuxda ugu xidhan yahay biyaha, mana jirto kala soocida dareeraha adag ee u dhexeeya labada;
(2) Koolada isku dhafan waxay ku jirtaa xaalad isku mid ah, oo dusha sare waa siman oo siman;
(3) Midabka koollada isku dhafan waxay ku dhow yihiin midab la'aan iyo daah-furnaan, mana jiraan waxyaabo granular ah oo ku jira koollada.Waxay qaadataa 10 ilaa 20 saacadood laga bilaabo marka darajada dhoobada ee antelope methyl cellulose la geliyo haanta wax lagu duubo oo lagu qaso biyo ilaa heerka methyl cellulose uu si buuxda u milmay.
