Enwere ụlọ ọrụ monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, nahydroxyethyl cellulose, nke a na-ejikarị eme ihe. N'ime ụdị cellulose atọ, nke kacha sie ike ịmata bụ hydroxypropyl methylcellulose na hydroxyethyl cellulose. Ka anyị mata 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 nkwụsịtụ, ịgbasa, ịgbasa, flotation, njikọ, imepụta ihe nkiri, 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 ọmarịcha colloidal thickener nwere ihe ngwọta electrolyte dị elu.
2. E jiri ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ike ịgbasa nke HEC bụ nke kachasị njọ, ma colloid nchebe nwere 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 ma ọ bụ na-esi ísì ụtọ, n'ihi ya, ọ nwere ọtụtụ ihe solubility na njirimara viscosity, yana gelation na-abụghị thermal.
A na-eji HEC eme ihe: a na-ejikarị ya dị ka onye na-emepụta ihe, onye na-ahụ maka nchebe, nrapado, stabilizer na nkwadebe nke emulsion, jelii, ude, ude mmiri, ikpochapụ anya.
Ngwa ewebata Hydroxypropyl methylcellulose (HPMC):
1. Ụlọ ọrụ mkpuchi: dị ka onye na-agba agba, na-ekesa na stabilizer na ụlọ ọrụ mkpuchi, ọ nwere ezigbo ndakọrịta na mmiri ma ọ bụ ihe mgbaze organic. dị ka ihe na-ewepụ agba.
2. N'ichepụta seramiiki: a na-ejikarị eme ihe dị ka ihe eji eme ihe na-emepụta ngwaahịa seramiiki.
3. Ndị ọzọ: A na-ejikwa ngwaahịa a na akpụkpọ anụ, ụlọ ọrụ ngwaahịa akwụkwọ, nchekwa mkpụrụ osisi na akwụkwọ nri na ụlọ ọrụ textile, wdg.
4. Mbipụta ink: dị ka onye na-agba agba, na-ekesa na stabilizer na ụlọ ọrụ ink, ọ nwere ezigbo ndakọrịta na mmiri ma ọ bụ ihe mgbaze organic.
5. Plastic: eji dị ka onye na-ahapụ ebu, softener, lubricant, wdg.
6. Polyvinyl chloride: A na-eji ya dị ka onye na-ekesa na mmepụta nke polyvinyl chloride, ọ bụkwa isi ihe inyeaka maka nkwadebe nke PVC site na nkwusioru polymerization.
7. Ụlọ ọrụ na-ewu ihe: Dị ka onye na-ejigide mmiri na retarder maka ciment ájá slurry, ọ na-eme ka ájá slurry na-agbapụta. A na-eji ya dị ka ihe nkedo na tapawa plasta, gypsum, putty powder ma ọ bụ ihe ụlọ ndị ọzọ iji kwalite mgbasa na ịgbatị oge ọrụ. A na-eji ya eme ihe dị ka tapawa maka tileti seramiiki, marble, ihe ịchọ mma plastik, dị ka ihe na-eme ka ihe na-eme ka ọ dịkwuo mma, ọ pụkwara ibelata ọnụ ọgụgụ ciment. Njide mmiri nke HPMC nwere ike igbochi slurry site na ịgbawa n'ihi ihicha ngwa ngwa mgbe ngwa ngwa, ma welie ike mgbe ọ gbasịrị.
