Taw qhia
Chitosan yog ib tug linear polysaccharide tsim los ntawm randomly faib -({1}})-txuas D-glucosamine (deacetylated unit) thiab N-acetyl-D-glucosamine (acetylated unit). Nws yog tsim los ntawm kev kho cw thiab lwm yam crustacean plhaub nrog alkali sodium hydroxide.
Chitosan muaj ntau yam kev lag luam thiab siv tau biomedical. Nws tuaj yeem siv rau hauv kev ua liaj ua teb raws li kev kho cov noob thiab biopesticide, pab cov nroj tsuag tiv thaiv kab mob fungal. Nyob rau hauv winemaking nws yuav siv tau raws li ib tug fining neeg sawv cev, kuj pab tiv thaiv kom txhob lwj. Hauv kev lag luam, nws tuaj yeem siv rau hauv kev kho tus kheej polyurethane xim txheej. Hauv cov tshuaj, nws yuav muaj txiaj ntsig zoo hauv cov ntaub qhwv los txo cov ntshav thiab ua cov tshuaj tua kab mob; nws kuj tseem siv tau los pab xa cov tshuaj los ntawm daim tawv nqaij.
Ntau controversially, chitosan tau raug lees paub tias muaj kev siv los txo qis kev nqus rog, uas yuav ua rau nws muaj txiaj ntsig zoo rau kev noj zaub mov, tab sis muaj pov thawj tawm tsam qhov no.
Lwm yam kev siv chitosan uas tau tshawb fawb suav nrog siv los ua cov khoom noj muaj fiber ntau.

1. Cov tshuaj tua kab mob
2. Txiv hmab txiv ntoo thiab zaub preservatives
3. Cov tshuaj ntxiv rau cov zaub mov kho mob
4. Clarifying tus neeg saib xyuas rau cov kua txiv hmab txiv ntoo "
Agricultural Qib:
1. Hauv kev ua liaj ua teb, chitosan feem ntau yog siv los ua kev kho cov noob thiab cog kev loj hlob ntxiv, thiab ua cov tshuaj biopesticide uas muaj txiaj ntsig zoo uas txhawb nqa lub peev xwm ntawm cov nroj tsuag los tiv thaiv lawv tus kheej tiv thaiv kab mob fungal.
2. Raws li pub additives, tuaj yeem cuam tshuam thiab tua cov kab mob phem, txhim kho tsiaj kev tiv thaiv. "
Qib Industrial:
1. Chitosan muaj zoo adsorption yam ntxwv ntawm hnyav hlau ion, siv nyob rau hauv kev kho mob ntawm cov organic wastewater, dye wastewater, dej purification thiab textile kev lag luam.
2. Chitosan tseem tuaj yeem siv rau hauv kev lag luam ua ntawv, txhim kho lub zog qhuav thiab ntub dej ntawm daim ntawv thiab deg printability. "
Dej Soluble Qib:
Dej soluble qib Chitosan yog hloov los ntawm chitosan los ntawm carboxylation, dawb soluble nyob rau hauv dej thiab tus cwj pwm yog ruaj khov. Nws muaj kev nqus dej zoo heev, khaws cia noo noo, opsonization, kab mob inhibition, thiab lwm yam. Muaj feem xyuam rau ntau yam tshuaj pleev ib ce, xws li emollient cream, da dej gel, tu cream, mousse, ointment frost, emulsion thiab colloid tshuaj pleev ib ce, thiab lwm yam. antistaling tus neeg saib xyuas rau cov zaub mov, txiv hmab txiv ntoo thiab zaub, flocculant rau dej phwj kho mob, tshuaj sustained tso tus neeg saib xyuas, nontoxic adhesive, auxiliaries rau dyeing & luam ntawv thiab ntawv ua, thiab lwm yam.
Carboxymethyl Chitosan:
Carboxymethyl Chitosan yog lub siab dua ramification ntawm chitosan, uas muaj 100% dej solubility, zaj duab xis tsim muaj peev xwm, hnyav hlau chelation. Nws tau siv rau hauv cov tshuaj pleev ib ce, hnyav hlau chelate tus neeg saib xyuas, tshuaj tiv thaiv kev tso tawm tus neeg sawv cev, cog kev loj hlob regulator tus neeg saib xyuas, kev kho dej khib nyiab, thiab lwm yam.
