Cellulose Ether (HPMC, MC, HEC, EC, HPC, CMC, PAC)

Ethers Cellulose waa koox ka mid ah polymers-ka biyaha-milmi kara oo laga soo qaatay cellulose, polymer dabiici ah oo laga helo gidaarada unugyada dhirta. Waxaa si weyn loogu isticmaalaa warshado kala duwan si ay u dhumucoodaan, xasiliyaan, filim samaynta, iyo guryaha-haysashada biyaha. Halkan waxaa ah dulmar kooban oo ku saabsan noocyada caadiga ah ee ethers cellulose:

1. Hydroxypropyl Methylcellulose (HPMC): HPMC waa eter cellulose-ka badan oo si weyn loogu isticmaalo dhismaha, daawooyinka, daryeelka shakhsi ahaaneed, iyo warshadaha cuntada. Waxaa lagu yaqaanaa haynta biyaha, dhumucda, iyo sameynta filimada. HPMC waxa caadi ahaan loo isticmaalaa dhumucdiye, xidhe, iyo rheology wax ka beddelka hoobiye, xabagta tile, kaniiniyada dawooyinka, waxyaalaha la isku qurxiyo, iyo alaabta cuntada.
2. Methylcellulose (MC): MC wuxuu la mid yahay HPMC laakiin wuxuu leeyahay heer hoose oo lagu beddelo kooxaha methyl. Waxaa loo adeegsadaa codsiyada meelaha haynta biyaha hoose iyo viscosity-ka looga baahan yahay, sida qaabaynta dawooyinka, xalalka indhaha, iyo dhumucyada alaabta cuntada.
3. Hydroxyethyl Cellulose (HEC): HEC waa eter-ka cellulose kale oo si ballaaran loo isticmaalo oo caan ku ah xajinta biyaha iyo sifooyinka dhumucdooda. Waxaa caadi ahaan loo isticmaalaa qalabka dhismaha sida rinjiyada, dahaarka, iyo xabagta, iyo sidoo kale alaabta daryeelka shakhsi ahaaneed sida shaambada, looshannada, iyo kiriimyada.
4. Ethyl Cellulose (EC): EC waa eter cellulose ah oo lagu beddelay kooxaha ethyl. Waxa ugu horrayn loo adeegsadaa dawooyinka, dahaarka, iyo codsiyada khaaska ah halkaas oo filim-samaynteeda, xannibaaddeeda, iyo guryaha sii-daynta joogtada ahi faa'iido u leedahay. EC waxaa inta badan loo isticmaalaa sida maaddada dahaarka ee kiniiniyada iyo pellets ee hababka daawooyinka.
5. Hydroxypropyl Cellulose (HPC): HPC waa eter cellulose ah oo lagu beddelay kooxaha hydroxypropyl. Waxaa caadi ahaan loo isticmaalaa sidii dhumuc, xidhe, iyo wakiilka filim samaynta ee daawooyinka, alaabta daryeelka shakhsi ahaaneed, iyo codsiyada cuntada. HPC waxay bixisaa milmi heer sare ah, xakamaynta viscosity, iyo xasiloonida xalalka aqueous.
6. Carboxymethyl Cellulose (CMC): CMC waa ether cellulose biyo-milmi leh oo ka soo jeeda cellulose by karboxymethylation. Waxaa si weyn loo isticmaalaa sidii dhumuc weyn, xasiliye, iyo xiraha alaabta cuntada, daawooyinka, alaabta daryeelka shakhsi ahaaneed, iyo codsiyada warshadaha. CMC waxay samaysaa xalal cad oo muuqda waxaana inta badan loo isticmaalaa sidii wakiilka dhumucyada suugada, dhaymada, iyo joojinta afka.
7. Polyanionic Cellulose (PAC): PAC waa eter cellulose ah oo lagu beddelay kooxaha anionic, sida caadiga ah karboxymethyl ama kooxaha phosphonate. Waxa ugu horrayn loo isticmaalaa sidii wax lagu daro xakamaynta luminta dareeraha ee dareeraha qodista ee sahaminta saliidda iyo gaaska. PAC waxay gacan ka geysataa dhimista luminta dareeraha, hagaajinta viscosity, iyo xasilinta dhoobada qodista ee heerkulka sare iyo xaaladaha cadaadiska sarreeya.

Ether-yadan cellulose-ku waxay bixiyaan hawlo kala duwan iyo codsiyo kala duwan oo warshado kala duwan ah, iyaga oo gacan ka geysanaya waxqabadka, xasilloonida, iyo tayada badeecado iyo qaabab badan.
