Farqiga u dhexeeya hydroxypropyl methylcellulose HPMC iyo hydroxyethyl cellulose HEC

Waxaa jira monosodium glutamate warshadeed, carboxymethyl cellulose, hydroxypropyl methyl cellulose, iyohydroxyethyl cellulose, kuwaas oo ah kuwa ugu badan ee la isticmaalo.Saddexda nooc ee cellulose, waxa ugu adag in la kala saaro waa hydroxypropyl methylcellulose iyo hydroxyethyl cellulose.Aynu ku kala saarno labadan nooc ee cellulose isticmaalkooda iyo hawlahooda.

Sida surfactant aan-ionic ahayn, hydroxyethyl cellulose waxay leedahay sifooyinka soo socda marka lagu daro hakinta, dhumucda, kala firdhinta, sabbaynta, isku-xidhka, samaynta filimada, haynta biyaha iyo bixinta kolloidyada ilaalinta:

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 ka kooban xalal korontolyte ah oo xoog-saaran.

2. Marka la barbar dhigo methyl cellulose la aqoonsan yahay iyo hydroxypropyl methyl cellulose, awoodda kala firdhisan ee HEC waa tan ugu xun, laakiin kolloid difaaca ayaa leh awoodda 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 qabow, mana soo da'do heerkulka sare ama karkarinta, sidaas darteed waxay leedahay noocyo kala duwan oo milmayn iyo sifooyin viscosity ah, iyo sidoo kale gelitaanka aan kuleylka ahayn.

Isticmaalka HEC: guud ahaan waxaa loo isticmaalaa sida wakiilka dhumuc, wakiilka ilaalinta, koollada, xasiliyaha iyo diyaarinta emulsion, jelly, boomaato, labeen, nadiifinta indhaha.

Hydroxypropyl methylcellulose (HPMC) hordhaca codsiga:

1. Warshadaha dahaarka: sida dhumuc weyn, kala firdhisan iyo xasilinta warshadaha daahan, waxa ay leedahay waafaqsan wanaagsan ee biyaha ama dareere organic.sida rinji-saar.

2. Wax-soo-saarka dhoobada: si ballaaran ayaa loo isticmaalaa sida binder ee soo saarista alaabta dhoobada.

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

4. Khadka daabacaadda: sida dhumuc weyn, kala firdhisan iyo xasiliye ee warshadaha khad, waxay leedahay waafaqid wanaagsan ee biyaha ama dareerayaasha organic.

5. Caaga: loo isticmaalo sida caaryada sii daaya, jilcisa, saliidaha, iwm.

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

7. Warshadaha dhismaha: Sida wakiilka biyaha-haynta iyo dib-u-dejiyaha slurry ciid sibidhka, waxay ka dhigaysaa slurry cammuudda mid la soo saari karo.Waxa loo isticmaalaa sida isku-xidhaha maraas-malaasta ah, gypsum, budada suufka ah ama qalabka kale ee dhismaha si loo hagaajiyo faafinta iyo u dheereeyo wakhtiga hawlgalka.Waxaa loo isticmaalaa sidii dhejis loogu talagalay dhoobada dhoobada, marmar, qurxinta caaga ah, sida kor u qaadida koollada, waxayna sidoo kale yareyn kartaa qadarka sibidhka.Haysashada biyaha ee HPMC waxay ka ilaalin kartaa slurry-ku inuu dillaaco sababtoo ah si degdeg ah u engejiya codsiga ka dib, iyo kor u qaadida xoogga ka dib qallafsanaanta.
