Hydroxyethyl cellulose bụ ọkara na ọkwa viscosity dị elu nke cellulose ether, nke a na-eji dị ka ihe na-eme ka ọkpụkpụ na stabilizer maka mkpuchi mmiri, karịsịa mgbe viscosity nchekwa dị elu na ngwa ngwa dị ala. Cellulose ether dị mfe ịgbasa na mmiri oyi na pH uru ≤ 7, ma ọ dị mfe agglomerate na alkaline mmiri mmiri na pH uru ≥ 7.5, n'ihi ya, anyị ga-aṅa ntị na dispersibility nke cellulose ether.
Atụmatụ na ojiji nke hydroxyethyl cellulose:
1. Anti-enzyme na-abụghị ionic mmiri thickener, nke a pụrụ iji na a dịgasị iche iche nke pH uru (PH = 2-12).
2. Ọ dị mfe ịgbasa, enwere ike ịgbakwunye ya ozugbo n'ụdị ntụ ntụ ma ọ bụ n'ụdị slurry mgbe ị na-egweri pigmenti na ndị na-ejuputa.
3. Ezigbo ihe owuwu. Ọ nwere uru dị n'ichekwa ọrụ, ọ naghị adị mfe ntapu na kpọgidere ya, yana ezigbo nguzogide nfesa.
4. Ezi ndakọrịta dị iche iche surfactants na preservatives eji na latex agba.
5. Viscosity nchekwa ahụ kwụsiri ike, nke nwere ike igbochi viscosity nke agba latex ka ọ ghara ibelata n'ihi mmebi nke enzymes n'ozuzu hydroxyethyl cellulose.
Njirimara nke Hydroxyethyl Cellulose
Hydroxyethyl cellulose ether bụ polymer na-abụghị ionic mmiri soluble. Ọ bụ ntụ ntụ na-acha ọcha ma ọ bụ dị ọkụ na-eru n'ụzọ dị mfe. N'ozuzu, a naghị edozi ya n'ọtụtụ ihe mgbaze organic
1. HEC na-agbaze n'ime mmiri ọkụ ma ọ bụ mmiri oyi, ọ naghị eme ka ọ dị elu 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.
2. Ọ bụ na-abụghị ionic na ike ibikọ ọnụ na ndị ọzọ mmiri-soluble polymers, surfactants, na salts. Ọ bụ ezigbo colloidal thickener maka ihe ngwọta nwere elu-etinye uche electrolytes.
3. Ikike njide mmiri dị okpukpu abụọ dị elu karịa nke methyl cellulose, ọ na-enwekwa usoro nchịkwa ka mma.
4. N'iji ya tụnyere methyl cellulose a ma ama na hydroxypropyl methyl cellulose, ike mgbasa nke HEC bụ nke kachasị njọ, ma nchebe colloid ike bụ ike kachasị ike (cha).

Na-emetụta arụmọrụ ọrụ, dị ka: mkpuchi mkpuchi, nkwụsị nfesa, nkwụsị nkwụsị; Ọdịdị netwọk pụrụ iche nke cellulose ether nwere ike ime ka ntụ ntụ dị na usoro mkpuchi, mee ka nhazi ya kwụsị, ma mee ka usoro ahụ nweta mmetụta nchekwa dị mma.
Ezigbo mgbochi mmiri
Mgbe ihe nkiri agba agbachara kpamkpam, ọ nwere oke mmiri na-eguzogide. Nke a na-egosipụta karịsịa uru nke mmiri na-eguzogide ya na usoro nhazi elu-PVC. Site na ndị mba ọzọ na usoro ndị China, na usoro PVC dị elu, ọnụọgụ cellulose ether agbakwunyere bụ isi 4-6‰.
ezigbo njide mmiri
Hydroxyethyl cellulose nwere ike ịgbatị oge ikpughe ma na-achịkwa oge ihicha iji nweta nhazi ihe nkiri ka mma; N'etiti ha, njide mmiri nke methyl cellulose na hypromellose na-adaba nke ọma karịa 40 ° C, na ụfọdụ ọmụmụ mba ọzọ kwenyere na ọ nwere ike belata 50% , ohere nke nsogbu n'oge okpomọkụ na elu okpomọkụ na-abawanye nke ukwuu.
Ezi nkwụsi ike iji belata flocculation nke agba
Wepụ sedimentation, syneresis na flocculation; ka ọ dị ugbu a, hydroxyethyl cellulose ether bụ ngwaahịa na-abụghị ionic. Ọ naghị emeghachi omume na mgbakwunye dị iche iche na sistemụ.
Ndakọrịta dị mma na usoro ọtụtụ agba
Nkwekọrịta dị mma nke agba agba, pigmenti na ihe ndochi; hydroxyethyl cellulose ether nwere mmepe agba kachasị mma, ma mgbe emezigharịrị, dị ka methyl na ethyl, a ga-enwe ihe ize ndụ zoro ezo nke ndakọrịta ụcha.
Ndakọrịta dị mma na akụrụngwa dị iche iche
