Focus on Cellulose ethers

Kedu ihe dị iche na HPMC na HEC?

HPMC bụ Hydroxypropyl methyl cellulose ether na HEC bụ hydroxyethyl cellulose ether.

Hydroxypropyl methyl cellulose (HPMC) mmalite:

1, ụlọ ọrụ ihe owuwu: dị ka onye na-ejigide mmiri na silt slurry mmiri, retarder na-eme ka slurry pumping. Na plasta, gypsum, putty ntụ ntụ ma ọ bụ ihe eji ewu ụlọ ndị ọzọ dị ka nrapado, na-emeziwanye daub ma mee ka oge ọrụ dịkwuo ogologo. A na-eji maka pasting seramiiki tile, marble, plastic decoration, mado ike gị n'ụlọnga, ka nwere ike ibelata ciment onunu ogwu.HPMCarụmọrụ njigide mmiri na-eme ka slurry mgbe ngwa ngwa agaghị abụ n'ihi na akọrọ ngwa ngwa na mgbawa, welie ike mgbe hardening.

2, seramiiki n'ichepụta: ọtụtụ ebe a na-eji dị ka nrapado na seramiiki ngwaahịa n'ichepụta.

3, ụlọ ọrụ mkpuchi: na ụlọ ọrụ mkpuchi dị ka onye na-ekpo ọkụ, onye na-ekesa na stabilizer, na mmiri ma ọ bụ ihe mgbaze organic nwere ezigbo solubility. Dị ka ihe na-ewepụ agba.

4, mbipụta ink: na ink ụlọ ọrụ dị ka a thickener, dispersant na stabilizer, na mmiri ma ọ bụ organic solvents nwere ezigbo solubility.

5, plastic: maka akpụ ntọhapụ, softener, mmanu, wdg.

6, PVC: PVC mmepụta dị ka a dispersant, nkwusioru polymerization nkwadebe nke PVC isi auxiliaries. 7, Ndị ọzọ: a na-ejikwa ngwaahịa a na akpụkpọ anụ, ụlọ ọrụ ngwaahịa akwụkwọ, nchekwa mkpụrụ osisi na akwukwo nri na ụlọ ọrụ textile.

Hydroxyethyl cellulose (HEC) mmalite:

HEC Hydroxyethyl cellulose, dị ka ụdị nonionic surfactant, e wezụga ndim, sere n'elu, sere n'elu, na film-akpụ, dispersion, mmiri, na-enye a colloid nchebe, nwekwara ihe ndị a Njirimara:

1, HEC soluble na mmiri ọkụ ma ọ bụ mmiri oyi, na-ekpo ọkụ ma ọ bụ na-esi esi adịghị mmiri ozuzo, na-eme ka ọ nwee ọtụtụ ihe solubility na viscosity Njirimara, na gel na-abụghị thermal;

2, ya na-abụghị ionic nwere ike ibikọ ọnụ na a dịgasị iche iche nke ọzọ mmiri-soluble polymers, surfactants, salts, bụ magburu onwe colloidal thickener nwere elu ịta nke electrolyte ngwọta;

3, ikike njigide mmiri dị elu okpukpu abụọ karịa methyl cellulose, nke nwere usoro nhazi nke ọma, 4, ikike mgbasa ozi HEC ma e jiri ya tụnyere methyl cellulose ghọtara na hydroxypropyl methyl cellulose dispersion ikike bụ nke kasị njọ, ma colloidal nchebe ikike bụ ike kasị mma.

ojiji: a na-ejikarị eme ihe dị ka onye na-ebu ibu, onye na-echebe ya, nrapado, stabilizer na mgbakwunye na nkwadebe nke emulsion, jelii, ude, ude mmiri, onye na-ekpochapụ anya, suppository na mbadamba nkume, nke a na-ejikwa dị ka gel hydrophilic, skeleton material, nkwadebe nke ọkpụkpụ ụdị kwadoro ntọhapụ. nkwadebe, nwekwara ike iji dị ka stabilizer na nri.
