Chitosan nitrate

1. Taw qhia

Chitosan nitrate yog dej - soluble derivative ntawm chitosan, tau los ntawm cov tshuaj tiv thaiv ntawm ntuj chitosan nrog nitric acid. Raws li cov khoom hloov pauv polysaccharide, nws tau txais txiaj ntsig zoo heev biocompatibility thiab biodegradability ntawm chitosan thaum muaj kev txhim kho solubility thiab electrorheological zog. Qhov no tsis muaj ntxhiab tsw tawm - cov hmoov dawb tsim cov kua ntshiab, pob tshab thiab ruaj khov thaum yaj hauv dej, ua rau nws siv dav hauv ntau yam xws li zaub mov, tshuaj txhua hnub, kev ua liaj ua teb thiab biomaterials.

(2) Thickener thiab Emulsifier: Ntxiv 0.5% - 1% ntawm nws rau cov txiv hmab txiv ntoo thiab zaub thiab cov khoom noj tuaj yeem txhim kho cov viscosity ntawm cov khoom thiab tiv thaiv stratification lossis nag lossis daus thaum khaws cia.

(3) Cov Khoom Siv Ntim Khoom Noj: Nws tuaj yeem siv los npaj cov ntim khoom noj. Cov yeeb yaj kiab tsim muaj cov khoom thaiv zoo, uas tuaj yeem ua rau qeeb oxidation ntawm cov zaub mov thiab tswj cov khoom noj tshiab.

3.2.Kev lag luam tshuaj txhua hnub

(1) Cov Khoom Siv Kho Hniav: Nws tuaj yeem muab ntxiv rau cov tshuaj pleev, tshuaj pleev thiab lwm yam khoom. Nws cov yeeb yaj kiab - tsim cov cuab yeej tuaj yeem tsim muaj kev tiv thaiv ntawm daim tawv nqaij kom kaw hauv cov dej noo thiab tiv thaiv ib puag ncig stimuli. Nyob rau tib lub sijhawm, nws tuaj yeem txhawb kev nkag mus ntawm cov khoom xyaw nquag hauv cov khoom tu tawv nqaij thiab pab txhim kho daim tawv nqaij elasticity thiab kev ntxhib los mos.

(2) Cov Khoom Siv Kho Plaub Hau: Raws li cov tshuaj ntxiv hauv cov tshuaj zawv plaub hau thiab cov tshuaj kho kom zoo, nws tuaj yeem txhim kho cov dej noo khaws cov plaub hau, txo cov dryness thiab frizz, thiab ua rau cov plaub hau softer thiab smoother.

3.3.Agriculture

Nws tuaj yeem siv los ua tus neeg sawv cev ua liaj ua teb. Nws tuaj yeem raug formulated rau hauv ib qho kev daws thiab txau rau cov qoob loo. Nws tsis tsuas yog pab txhim kho cov dej - tuav lub peev xwm ntawm cov av nyob ib ncig ntawm lub hauv paus system ntawm cov qoob loo tab sis kuj inhibits kev loj hlob ntawm cov kab mob phem nyob rau hauv cov av, yog li txhawb kev noj qab haus huv ntawm cov qoob loo.

3.4.Biomaterials teb

Nws ua hauj lwm ua ib qho tseem ceeb nruab nrab rau biomaterials thiab yuav siv tau nyob rau hauv kev npaj ntawm nanomaterials thiab electrolyte daim nyias nyias. Nws cov biocompatibility zoo ua kom ntseeg tau tias cov khoom siv biomaterials tuaj yeem hloov kho kom zoo rau ib puag ncig lom neeg, uas muaj cov ntawv thov dav dav hauv kev lag luam biomedical engineering.

6. Kev ruaj ntseg thiab kev nyab xeeb

Kev ruaj ntseg:

Nyob rau hauv cov xwm txheej khaws cia (lub hnab ntim cov ntawv txhuas los yog cov ntawv nruas, tsis txhob ya raws thiab kev sib kis), lub txee lub neej yog 24 lub hlis. Txawm tias tom qab qhib, cov khoom tseem nyob ruaj khov rau 3-6 lub hlis yog tias rov ua dua tam sim ntawd, tsis muaj kev hloov pauv tseem ceeb hauv purity, solubility, lossis antimicrobial.
