Isticmaalka iyo kala duwanaanshaha ugu weyn ee hydroxypropyl methylcellulose HPMC iyo hydroxyethyl cellulose HEC

Isticmaalka iyo kala duwanaanshaha ugu weyn ee hydroxypropyl methylcellulose HPMC iyo hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, iyo hydroxyethyl cellulose oo leh monosodium glutamate warshadaha ayaa loo isticmaalaa qadarka ugu badan.Waxa ugu adag in la kala saaro saddexdan nooc ee cellulose waa hydroxypropyl methylcellulose iyo hydroxyethyl cellulose.Hoos waxaan ku kala saari doonaa labadan nooc ee cellulose iyada oo loo marayo adeegsigooda iyo shaqadooda.

Sida surfactant aan-ionic ahayn, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro shaqooyinka joojinta, dhumucda, kala firdhinta, sabaynta, isku xidhka, samaynta filimada, haynta biyaha iyo bixinta kolloid ilaalin ah:

1. HEC lafteedu waa non-ionic waxayna la noolaan kartaa tiro balaadhan oo ah polymers kale oo biyo-milmi kara, surfactants, iyo cusbo.Waa dhumuc weyn oo kolloidal ah oo loogu talagalay xalalka ka kooban elektrolytka-fiirsashada sare.

2. Marka la barbar dhigo methyl cellulose ee la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhisan ee HEC waa tan ugu xun, laakiin awoodda kolloid ilaalinta ayaa ah kan ugu xooggan.

3. Awoodda haynta biyuhu waxay laban laab ka badan tahay tan methyl cellulose, waxayna leedahay nidaaminta qulqulka wanaagsan.

4. HEC waxay ku milmaysaa biyo kulul ama biyo qabow, oo kuma soo da'aan heerkulka sare ama karkarinta, taas oo ka dhigaysa inay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity, iyo gelation non-thermal.

Isticmaalka HEC: guud ahaan loo isticmaalo sidii dhumuc ahaan, wakiilka ilaalinta, koollada, xasiliyaha iyo diyaarinta emulsion, jelly, boomaato, kareem, indho cad.

Hydroxypropyl methylcellulose (HPMC) hordhaca codsiga:

1. Warshadaha dahaarka: Waxaa loo isticmaalaa sidii dhumuc, kala firdhiyo iyo xasilinta warshadaha daahan, oo waxay leedahay waafaqsan wanaagsan ee biyaha ama dareerayaasha organic.Sida rinji-saar.

2. Warshadaha wax soo saarka dhoobada: Waxaa si weyn loo isticmaalaa sida xidhe ee wax soo saarka dhoobada.

3. Kuwo kale: Alaabtan ayaa sidoo kale si weyn loogu isticmaalaa hargaha, alaabta waraaqaha, ilaalinta khudradda iyo khudaarta iyo warshadaha dharka, iwm.

4. Khad daabacaadda: Waxa loo isticmaalaa dhumuc ahaan, kala firdhisa iyo xasilinta warshadaha khadka, waxayna leedahay iswaafajin wanaagsan oo biyaha ama dareeraha organic.

5. Caaga: loo isticmaalo sidii samaynta wakiilka sii daynta, jilcisa, saliidaha, iwm.

6. Polyvinyl chloride: Waxaa loo isticmaalaa sida kala firdhiso soo saarista chloride polyvinyl, waana wakiilka ugu muhiimsan ee diyaarinta PVC by polymerization hakinta.ah

7. Warshadaha dhismaha: Sida wakiilka biyaha-haynta iyo dib-u-dejinta slurry ciid sibidhka, waxay ka dhigi kartaa hoobiye mid la soo saari karo.Malaasta, gypsum, budada suufka ah ama qalabka kale ee dhismaha si loo hagaajiyo faafinta iyo u dheereeyo wakhtiga shaqada.Waxaa loo isticmaali karaa sidii foorno dhejis ah, marmar, qurxinta caagga ah, xoojinta koollada, iyo sidoo kale waxay yareyn kartaa qaddarka sibidhka.Waxqabadka biyo-haynta ee HPMC waxay ka hortagtaa slurry-ka inuu dillaaco sababtoo ah si dhakhso ah u qallaji codsiga ka dib, waxayna kordhisaa xoogga ka dib qallafsanaanta.
