N'ogbe HEC Hydroxyethyl Cellulose

Hydroxyethyl cellulose (hydroxyethyl cellulose) b? ihe na-ab?gh? ionic mmiri soluble cellulose ether, na-emekar? na-ap?ta na-acha ?cha na icha mmirimmiri odo n'?d? nt? nt?.

Ezigbo mmiri solubility: ? nwere ike ?gbaze ngwa ngwa na mmiri oyi iji mep?ta ngw?ta na-enwegh? at? na otu.

Mmet?ta siri ike na nkw?si ike: na-abawanye viscosity nke ngw?ta nke ?ma, melite nkw?si ike nke usoro ah?, gbochie mmiri ozuzo na delamination.

Njirimara mmiri nke pseudoplastic: ihe ngw?ta nwere nnukwu viscosity na ?n? ?g?g? d? ala, na viscosity na-ebelata na ?n? ?g?g? d? elu, nke d? mma maka iwu na ngwa.

Nguzogide nnu: ? ka nwere ike ?n?gide na-ar? ?r? nke ?ma n'?d? ngw?ta nnu.

Nkw?si ike pH: ar?m?r? kw?siri ike kar?a oke pH.

Ubi mkpuchi: D? ka onye na-ah? maka ?gbat? na onye na-ah? maka njikwa rheological, melite ar?m?r? ihe owuwu na nkw?si ike nchekwa nke mkpuchi.

D?ka ?m?maat?, na mkpuchi ?l? nke dabeere na mmiri, agba na-ad? mfe ?cha na mkpuchi ah? b? otu ma d? nro.

?l? ?r? kem?kal? kwa ?b?ch?: A na-eji ncha ntutu, ?sa ah?, ude mmiri na ngwaah?a nd? ?z? na-abawanye nkw?si ike na nkw?si ike.

Mwep?ta mman?: D? ka ihe mgbakwunye na mmiri na-egwup?ta mmiri na mmiri mmecha, ? na-ar? ?r? nke ?ba ?ba viscosity na ibelata mfu filtration.

Ogige ?gw?: nrapado, nkwusioru, wdg, nke enwere ike iji d? ka mbadamba nkume.

A na-akwadokar? ya site na cellulose site na mmeghachi omume etherification na ethylene oxide.

Site na mm?ba na-ar?wanye elu maka mgbakwunye na-ar? ?r? d? elu na ?l? ?r? d? iche iche, echiche ah?a maka Hydroxyethyl Cellulose d? ezigbo mma. N'?kwalite mmepe na-aga n'ihu nke mkpuchi enyi na gburugburu ebe obibi, ngwaah?a kem?kal? d? elu kwa ?b?ch? yana tekn?z? mm?p?ta mman?, a na-at? anya na ?ch?r? ah?a ya ga-aga n'ihu.

Mgbe ? na-echekwa kwes?r? ??a nt? na mmiri mmiri, nchebe anyanw?, zere k?ntakt? na oxidants siri ike.

Ekwes?r? iji nway?? kpalite ngw?ta ah? ka ? ghara ?ch?k?ta ya.

Na usoro ngwa d? iche iche, ? d? mkpa iji bulie ego mgbakwunye na iji ?n?d? d?ka ?n?d? d? iche iche si d?.

N'?ch?k?ta, Hydroxyethyl Cellulose, nke nwere ihe nd? p?r? iche ya na ?t?t? ihe eji eme ihe, na-ar? ?r? d? mkpa n'?t?t? ebe, na-enye nkwa siri ike maka mmelite ngwaah?a na ar?m?r?.
