Ethyl cellulose

Ethyl cellulose bụ ihe sitere na cellulose, polymer eke dị na osisi. A na-emepụta ya site na mmeghachi omume nke cellulose na ethyl chloride n'ihu onye na-emepụta ihe. A na-eji Ethyl cellulose eme ihe n'ọtụtụ ebe n'ime ụlọ ọrụ dị iche iche n'ihi njirimara ya pụrụ iche na ntụgharị ya. Nke a bụ ụfọdụ njirimara na ngwa nke ethyl cellulose:

1. Enweghi ike na mmiri: Ethyl cellulose bụ ihe na-adịghị edozi na mmiri, nke na-eme ka ọ dị mma maka ngwa ebe a chọrọ nkwụsị mmiri. Ngwongwo a na-enyekwa ohere iji ya mee ihe dị ka mkpuchi nchebe na ọgwụ ọgwụ na ihe mgbochi na nkwakọ ngwaahịa nri.
2. Solubility na Organic Solvents: Ethyl cellulose bụ soluble n'ọtụtụ ihe mgbaze organic, gụnyere ethanol, acetone, na chloroform. Solubility a na-eme ka ọ dị mfe ịhazi na ịmepụta ngwaahịa dị iche iche, dị ka mkpuchi, ihe nkiri, na ink.
3. Ikike imepụta ihe nkiri: Ethyl cellulose nwere ikike imepụta ihe nkiri na-agbanwe agbanwe na nke na-adịgide adịgide mgbe ihicha. A na-eji ihe onwunwe a eme ihe na ngwa ndị dị ka ihe mkpuchi mbadamba na ọgwụ, ebe ọ na-enye mkpuchi nchebe maka ihe ndị na-arụ ọrụ.
4. Thermoplasticity: Ethyl cellulose na-egosipụta omume thermoplastic, nke pụtara na ọ nwere ike ime ka ọ dị nro na ịkpụzi ya mgbe ọ na-ekpo ọkụ wee sie ike mgbe ọ dị jụụ. Ngwongwo a na-eme ka ọ dị mma maka ojiji na nrapado na-agbaze na-ekpo ọkụ na plastik nwere ike ịkpụ.
5. Inertness kemịkalụ: Ethyl cellulose bụ kemịkalụ inert na-eguzogide acid, alkalis, na ọtụtụ ihe mgbaze organic. Ngwongwo a na-eme ka ọ dị mma iji mee ihe na nhazi ebe nkwụsi ike na ndakọrịta na ihe ndị ọzọ dị mkpa.
6. Biocompatibility: A na-ahụta Ethyl cellulose dị ka nchekwa (GRAS) maka iji ọgwụ, nri, na ngwaahịa ịchọ mma. Ọ bụghị ihe na-egbu egbu na ọ dịghị etinye ihe ize ndụ nke mmetụta ọjọọ mgbe ejiri ya mee ihe dịka e bu n'obi.
7. Mwepụta a na-achịkwa: A na-ejikarị Ethyl cellulose eme ihe na usoro ọgwụ iji chịkwaa ntọhapụ nke ihe ndị na-arụ ọrụ. Site n'ịgbanwe ọkpụrụkpụ nke mkpuchi ethyl cellulose na mbadamba nkume ma ọ bụ pellets, ọnụego ntọhapụ ọgwụ nwere ike gbanwee iji nweta profaịlụ ntọhapụ agbatị ma ọ bụ na-adịgide adịgide.
8. Ihe nkedo na Thickener: A na-eji Ethyl cellulose mee ihe dị ka ihe na-ejikọta ya na ngwa ngwa dị iche iche, gụnyere ink, mkpuchi, na adhesives. Ọ mma na rheological Njirimara nke formulations na-enyere aka nweta chọrọ agbanwe agbanwe na viscosity.

ethyl cellulose bụ polymer vasatail nwere ọtụtụ ngwa na ụlọ ọrụ dị ka ọgwụ, nri, ihe ịchọ mma, mkpuchi, na adhesives. Ngwakọta ya pụrụ iche nke ihe onwunwe na-eme ka ọ bụrụ ihe bara uru n'ọtụtụ nhazi, ebe ọ na-enye aka na nkwụsi ike, ịrụ ọrụ na ịrụ ọrụ.
