A na-eji hydroxyethyl cellulose mee ihe na agba

Taa, anyị ga-agwa gị banyere ojiji a na-ejikarị hydroxyethyl cellulose na agba na mkpuchi.Agba, nke a na-akpọkarị mkpuchi na China.A na-ekpuchi ihe a na-akpọ mkpuchi n'elu ihe a ga-echebe ma ọ bụ chọọ mma, ma nwee ike ịmepụta ihe nkiri na-aga n'ihu nke na-ejikọta ya na ihe a ga-ekpuchi.

Kedu ihe bụ hydroxyethyl cellulose?

Hydroxyethyl cellulose (HEC), a na-acha ọcha ma ọ bụ ìhè edo edo, enweghị isi, na-adịghị egbu egbu fibrous ma ọ bụ powdery siri ike, kwadebere site etherification nke alkaline cellulose na ethylene oxide (ma ọ bụ chlorohydrin), nke genus Nonionic soluble cellulose ethers.N'ihi na HEC nwere ezigbo ihe nke ịgbasa, nkwụsịtụ, ịgbasa, emulsifying, bonding, film-forming, na-echebe mmiri na inye nchebe colloid, a na-eji ya eme ihe n'ọtụtụ ebe na nchọpụta mmanụ, mkpuchi, ihe owuwu, ọgwụ na nri, textiles, papermaking and polymers.Polymerization na mpaghara ndị ọzọ.

Kedu ihe na-eme mgbe hydroxyethyl cellulose zutere na mmiriagba?

Dị ka a na-abụghị ionic surfactant, hydroxyethyl cellulose nwere ihe ndị a na mgbakwunye na ndim, suspending, bonding, flotation, film-forming, dispersing, water njide na inye nchebe colloid:
