Kedu ihe ethylcellulose si mee?

Ethyl cellulose bụ polymer sịntetik nke sitere na cellulose eke, ihe a na-emekarị nke mgbidi cell osisi.Mmepụta nke ethyl cellulose gụnyere mgbanwe kemịkalụ nke cellulose eke sitere na iji ethyl chloride na ihe na-akpali akpali iji mepụta ethyl ether nke sitere na cellulose.

Usoro na-amalite site na ịsacha cellulose site na isi ihe ọkụkụ, dị ka osisi pulp ma ọ bụ owu.A na-agbazekwa cellulose dị ọcha na ngwakọta nke ihe mgbaze, dị ka ethanol na mmiri, iji mepụta ngwọta viscous.A na-agbakwunye Ethyl chloride na ngwọta ya, yana ihe na-eme ka ọ dị mma, nke na-eme ka mmeghachi omume dị n'etiti cellulose na ethyl chloride dị mfe.

N'oge mmeghachi omume ahụ, molekul ethyl chloride na-anọchi ụfọdụ n'ime ìgwè hydroxyl na agbụ cellulose, na-eme ka e guzobe ethyl cellulose.Ogo nke ethoxylation, ma ọ bụ ọnụ ọgụgụ nke ethyl dị iche iche jikọtara na nkeji glucose ọ bụla na agbụ cellulose, nwere ike ịchịkwa n'oge mmeghachi omume iji mepụta ethyl cellulose nwere ihe dị iche iche na njirimara solubility.

Mgbe mmeghachi omume ahụ mechara, ethyl cellulose na-esi na ya pụta dị ọcha ma kpoo ya iji wepụ ihe mgbaze ma ọ bụ adịghị ọcha ọ bụla.Ngwaahịa ikpeazụ bụ ọcha ma ọ bụ ntụ ntụ na-acha odo odo nke na-agbaze n'ọtụtụ dịgasị iche iche nke ihe ndị na-emepụta ihe na-edozi ahụ, ma na-adịghị edozi na mmiri.

N'ozuzu, ethyl cellulose bụ polymer sịntetik nke sitere na cellulose eke sitere na usoro mgbanwe kemịkalụ nke gụnyere mgbakwunye nke otu ethyl na agbụ cellulose.
