Fiber:
Fiber (US: Fiber; English: Fiber) na-ezo aka na ihe mejupụtara filaments na-aga n'ihu ma ọ bụ nke na-akwụsị. Dị ka eriri osisi, ntutu anụ, eriri silk, eriri sịntetik, wdg.
Cellulose:
Cellulose bụ macromolecular polysaccharide nke mejupụtara glucose na bụ isi ihe nhazi mgbidi cell osisi. N'ebe okpomọkụ dị n'ime ụlọ, cellulose anaghị amị mkpụrụ n'ime mmiri ma ọ bụ n'ime ihe mgbaze nkịtị. Ọdịnaya cellulose nke owu dị nso 100%, na-eme ka ọ bụrụ isi iyi sitere na cellulose kacha dị ọcha. Na osisi n'ozuzu, cellulose bụ 40-50%, na e nwere 10-30% hemicellulose na 20-30% lignin.
Ọdịiche dị n'etiti cellulose (n'aka nri) na starch (aka ekpe):
N'ikwu okwu n'ozuzu, ma starch na cellulose bụ polysaccharides macromolecular, na usoro mkpụrụ ndụ nwere ike ịkọwa dị ka (C6H10O5) n. Arọ molekụla nke cellulose karịrị nke starch, na cellulose nwere ike ire ere iji mepụta starch. Cellulose bụ D-glucose na β-1,4 glycoside macromolecular polysaccharides mejupụtara nke agbụ, ebe starch kpụrụ site α-1,4 glycosidic bonds. A naghị ekewa cellulose n'ozuzu ya, mana starch na-ejikọta ya na 1,6 glycosidic bonds. Cellulose anaghị agbaze na mmiri, ebe starch na-agbaze na mmiri ọkụ. Cellulose adịghị enwe mmetụta nke amylase na ọ naghị atụgharị acha anụnụ anụnụ mgbe ekpughere ya na ayodiin.
Cellulose ether:
The English aha nkecellulose etherbụ cellulose ether, nke bụ polymer compound na ether Ọdịdị nke cellulose mere. Ọ bụ ngwaahịa nke mmeghachi omume kemịkalụ nke cellulose (osisi) nwere ihe etherification. Dị ka usoro nhazi nke kemịkalụ nke nnọchi anya mgbe etherification gasịrị, enwere ike kewaa ya na anionic, cationic na nonionic ethers. Dabere na etherification gị n'ụlọnga, e nwere methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl hydroxyethyl cellulose, carboxymethyl hydroxyethyl cellulose, cellulose cellulose, carboxymethyl hydroxyethyl cellulose, cellulose cellulose, carboxymethyl hydroxyethyl cellulose. A na-akpọkwa ether cellulose, nke bụ aha na-adịghị mma, a na-akpọkwa ya cellulose (ma ọ bụ ether) n'ụzọ ziri ezi.
Usoro siri ike nke Cellulose Ether Thickener:
Cellulose ether thickeners bụ ndị na-abụghị ionic thickeners na thickeners tumadi site hydration na njikọ dị n'etiti ụmụ irighiri ihe.
Agbụ polymer nke cellulose ether dị mfe ịmepụta njikọ hydrogen na mmiri n'ime mmiri, na njikọ hydrogen na-eme ka ọ nwee nnukwu hydration na njikọ nke inter-molecular.
Mgbecellulose ethera na-agbakwunye thickener na agba latex, ọ na-amịkọrọ mmiri buru ibu, na-eme ka olu nke ya gbasaa nke ukwuu, na-ebelata ohere ohere maka pigmenti, ihe nchacha na akụkụ latex;
N'otu oge ahụ, cellulose ether molecular chains na-ejikọta ọnụ iji mepụta usoro netwọk nke akụkụ atọ, na pigmenti, fillers na latex particles na-agba gburugburu n'etiti ntupu na enweghị ike ịgba ọsọ n'efu.
