Ethyl Cellulose- EC na-eweta

Ethyl cellulose bụ polima na-adịghị edozi mmiri nke sitere na cellulose, bioopolymer eke dị na mgbidi cell osisi. A na-eji ya eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, na nlekọta onwe onye, ​​​​n'ihi njirimara ya pụrụ iche, gụnyere solubility, ike ịmepụta ihe nkiri, na obere nsị. Isiokwu a ga-atụle njirimara, njikọ, na ngwa nke ethyl cellulose.

Njirimara nke Ethyl Cellulose Ethyl cellulose bụ ihe na-ekpo ọkụ nke na-agbaze n'ime ihe mgbaze organic, dị ka ethanol, mana ọ na-esighi ike na mmiri. Enwere ike idozi solubility nke ethyl cellulose site n'ịgbanwe ogo nke nnọchi ya, nke na-ezo aka ọnụ ọgụgụ ethyl otu n'otu glucose n'ime molekul cellulose. Ethyl cellulose nke nwere ogo dị elu nke nnọchi na-edozi ya na ihe ndị na-emepụta ihe na-edozi ahụ, ebe ndị nwere ọkwa dị ala nke dochie anya na-esighị ike.

A maara Ethyl cellulose maka ikike imepụta ihe nkiri mara mma ma enwere ike iji ya mepụta otu ihe nkiri kwụsiri ike. Ihe na-emepụta ihe nkiri nke ethyl cellulose nwere ike ime ka ọ dịkwuo mma site n'ịgbakwunye plasticizers, dị ka dibutyl phthalate ma ọ bụ triacetin, nke na-eme ka mgbanwe na ngbanwe nke ihe nkiri ahụ dịkwuo elu. A na-ejikarị ihe nkiri ethyl cellulose eme ihe na ụlọ ọrụ ọgwụ dị ka mkpuchi maka mbadamba nkume, capsules, na granules.

A na-emepụta njikọ nke Ethyl Cellulose Ethyl cellulose site na imeghachi cellulose na ethyl chloride n'ihu nke isi, dị ka sodium hydroxide ma ọ bụ potassium hydroxide. Mmeghachi omume gụnyere ngbanwe nke otu hydroxyl n'ime mkpụrụ ndụ cellulose na otu ethyl, na-eme ka e guzobe ethyl cellulose. Enwere ike ịchịkwa ogo nke nnọchi site n'ịgbanwe ọnọdụ mmeghachi omume, dị ka ntinye nke reactants na oge mmeghachi omume.

Ngwa nke Ethyl Cellulose Pharmaceuticals: A na-eji Ethyl cellulose eme ihe n'ọtụtụ ebe na ụlọ ọrụ ọgwụ n'ihi ikike imepụta ihe nkiri dị mma yana obere nsị. A na-eji ya dị ka ihe mkpuchi maka mbadamba nkume, capsules, na granules, nke na-eme ka nkwụsi ike ha dịkwuo mma ma na-egbochi ha ịgbasa na eriri afọ. A pụkwara iji mkpuchi ethyl cellulose mee ihe iji chịkwaa ntọhapụ nke ọgwụ ọjọọ site n'ịgbanwe ọnụego mgbasa ha.

Nri: A na-eji Ethyl cellulose eme ihe dị ka ihe mgbakwunye nri iji meziwanye udidi na nkwụsi ike nke ihe oriri. A na-ejikarị ya eme ihe dị ka ihe na-akpụ akpụ, ihe nkedo, na ihe nkwụsi ike n'ihe oriri ndị a na-edozi, dị ka ihe oriri, akwa akwa, na ihe ndị e ghere eghe. Ethyl cellulose nwekwara ike iji dị ka ihe mkpuchi maka mkpụrụ osisi na akwụkwọ nri iji gbasaa ndụ ha ma gbochie mmebi.

Nlekọta onwe onye: A na-eji Ethyl cellulose mee ihe na ngwaahịa nlekọta onwe onye dị iche iche, dị ka ihe ịchọ mma, shampoos, na lotions, n'ihi ike ịmepụta ihe nkiri na ihe ndị na-egbochi mmiri. A na-ejikarị ya eme ihe dị ka onye na-agba ume na stabilizer na ihe ịchọ mma, a pụkwara iji ya mee ihe dị ka onye na-emepụta ihe nkiri na nsị ntutu na ngwaahịa nhazi.

Ngwa ndị ọzọ: Ethyl cellulose na-eji ngwa ndị ọzọ dị iche iche, dị ka ink, mkpuchi, nrapado, na agba. A na-ejikarị ya eme ihe dị ka ihe nkedo na mkpuchi na dị ka ihe na-agba agba na ink. Ethyl cellulose nwekwara ike iji dị ka ihe mkpuchi mmiri na-eguzogide akwụkwọ na dị ka ihe nkedo maka ceramik.

Na nchịkọta, ethyl cellulose bụ polymer na-adịghị edozi mmiri nke sitere na cellulose nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere ọgwụ, nri, na nlekọta onwe onye. A maara ya maka ikike imepụta ihe nkiri dị mma, obere toxicity, na ihe na-egbochi mmiri, na-eme ka ọ dị mma maka ngwa dị iche iche.
