Isi ojiji na ọdịiche nke hydroxypropyl methylcellulose HPMC na hydroxyethyl cellulose HEC.

A na-eji Carboxymethyl cellulose, hydroxypropyl methyl cellulose, na hydroxyethyl cellulose nwere monosodium glutamate ụlọ ọrụ mmepụta ihe na nnukwu ego.Nke kacha sie ike ịmata ọdịiche dị n'etiti ụdị cellulose atọ a bụ hydroxypropyl methylcellulose na hydroxyethyl cellulose.N'okpuru ebe a, anyị ga-amata ọdịiche dị n'ụdị abụọ a nke cellulose site na ojiji na ọrụ ha.

Dị ka ihe na-abụghị ionic surfactant, hydroxyethyl cellulose nwere ihe ndị a na mgbakwunye na ọrụ nke nkwụsịtụ, ịgbasa, ịgbasa, na-ese n'elu mmiri, njikọ, ihe nkiri akpụ, njide mmiri na inye colloid nchebe:

1. HEC n'onwe ya abụghị ionic ma nwee ike ibikọ ọnụ na ọtụtụ polymers ndị ọzọ na-edozi mmiri, surfactants, na salts.Ọ bụ ezigbo colloidal thickener maka ihe ngwọta nwere elu-etinye uche electrolytes.

2. E jiri ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ike ịgbasa nke HEC bụ nke kachasị njọ, ma ikike colloid nchebe bụ ike kachasị ike.

3. Ikike njide mmiri dị okpukpu abụọ dị elu karịa nke methyl cellulose, ọ na-enwekwa usoro nchịkwa ka mma.

4. HEC na-agbaze na mmiri ọkụ ma ọ bụ mmiri oyi, ọ naghị eme ka ọ dị elu na okpomọkụ ma ọ bụ na-esi ísì ụtọ, nke na-eme ka ọ nwee ọdịdị dị iche iche nke solubility na viscosity, na gelation na-abụghị thermal.

A na-eji HEC eme ihe: a na-ejikarị eme ihe dị ka onye na-ekpuchi ihe, onye na-echebe ihe, nrapado, stabilizer na nkwadebe nke emulsion, jelii, ude, ude mmiri, anya doro anya.

Ngwa ewebata Hydroxypropyl methylcellulose (HPMC):

1. Ụlọ ọrụ mkpuchi: A na-eji ya dị ka onye na-agba agba, na-ekesa na stabilizer na ụlọ ọrụ mkpuchi, ma nwee ezigbo ndakọrịta na mmiri ma ọ bụ ihe mgbaze.Dị ka ihe na-ewepụ agba.

2. Ụlọ ọrụ mmepụta ihe seramiiki: A na-ejikarị ya eme ihe dị ka ihe eji eme ihe na-emepụta ngwaahịa seramiiki.

3. Ndị ọzọ: A na-ejikwa ngwaahịa a na akpụkpọ anụ, ngwaahịa akwụkwọ, nchekwa mkpụrụ osisi na akwụkwọ nri na ụlọ ọrụ textiles, wdg.

4. Mbipụta ink: A na-eji ya dị ka onye na-agba agba, na-ekesa na stabilizer na ụlọ ọrụ ink, ma nwee ezigbo ndakọrịta na mmiri ma ọ bụ ihe mgbaze organic.

5. Plastic: ejiri ya dị ka onye na-emepụta ihe ntọhapụ, softener, lubricant, wdg.

6. Polyvinyl chloride: A na-eji ya dị ka onye na-ekesa na mmepụta nke polyvinyl chloride, ọ bụkwa isi ihe enyemaka maka ịkwadebe PVC site na nkwụsịtụ polymerization.nke

7. Ụlọ ọrụ na-ewu ihe: Dị ka onye na-ejigide mmiri na retarder nke ciment ájá slurry, ọ nwere ike ime ka ngwa agha na-agbapụta.Na plasta, gypsum, putty ntụ ntụ ma ọ bụ ihe ndị ọzọ na-ewu ụlọ dị ka ihe eji eme ihe iji meziwanye mgbasa na ịgbatị oge ọrụ.Enwere ike iji ya dị ka taịlị mado, marble, ihe ịchọ mma rọba, nkwado mado, ma nwee ike belata ọnụ ọgụgụ ciment.Igwe mmiri na-ejigide mmiri nke HPMC na-egbochi slurry site na ịkụcha n'ihi ihicha ngwa ngwa mgbe ngwa ngwa, ma na-eme ka ike dịkwuo elu mgbe ọ gbasasịrị.
