Ndeipi muenzaniso wemheremellose ether?

Cellulose ana ana ana vana vanomiririra kirasi dzakasiyana siyana dzemakomputa dzinosungwa kubva kuCellulose, polysaccharide inowanikwa mumasero emaruva ezvirimwa. Iyi mishonga inoshandiswa zvakanyanya mumagirendi akasiyana siyana nekuda kwezvivakwa zvavo zvakasarudzika, kusanganisira kurerutsa, kusimbisa, firimu-fomu, uye kuchengetedza kwemvura, uye kuchengetedza kwemvura. Mukutsvagira uku kwakakura, isu tichasvetuka munyika yemasolose avaneta, vachiongorora chimiro chavo, zvivakwa, nzira dzeSynthesis, uye zvirongwa pamatunhu akasiyana.

1. Sumo kuCellulose anaVana:

Cellulose ana ana vana cellulose vanobva kune imwe yeiyo hydroxyl (-Ooh) mapoka eCellulose Polymer anotsiviwa nemapoka e-ether. Izvi zvinoshandisika zvinoshandura zvivakwa zve phomilose zve cellulose, chinopa icho chinonyura mumvura uye mamwe mashiromita, izvo zvisiri izvo zvine mamiriro echitunha. Iko kutsiva kwehydroxyl mapoka ane ether zvibodzwa zvinopa cellulose ether uye ine huwandu hwenzvimbo dzinodiwa, kusanganisira solubility, viscosity, firimu-inoumba kugona, uye kugadzikana kwekunyora.

2. Chimiro uye zvivakwa zve cellulose ana manyombe:

Chimiro che cellulose ana ana ana akasiyana zvichienderana nerudzi uye degree rekutsiva. Company Cellulose eter inosanganisira methyl celllose, ethyl cellulose, hydroxyl cellulose, hydroxyprosl cellulose, uye carboxymethyl cellulose. Aya maReivatives anoratidzira zvakasiyana-siyana zvivakwa, senge solubility, viscosity, maGel kuumbwa, uye kugadzikana kwekunyora, kuita kuti vakwanise kuita zvinoshanda zvakasiyana.

Semuenzaniso, methyl cellalose inonyura mumvura inotonhora asi inogadzira gel kana ichipiswa, ichiita kuti ive yakakodzera kuti zvibodzwa zvaida zvivakwa, zvakadai sezvigadzirwa zvekudya uye zvekudya zvemishonga. Ethilly Cellulose, kune rumwe rutivi, haanzwisisi mumvura asi anokanda mapfumo pasi, achizviita kuti ashandise mumatanho, anomisheni, uye anodzorwa-anodzora zvinodhaka.

3. Synthesis of cellulose ana manyadzo:

Cellulose ana vana kazhinji inowanzo kuvezwa kuburikidza nemakemikari kugadziridzwa kwe cellulose uchishandisa dzakasiyana siyana reagents uye maitiro emamiriro ezvinhu. Nzira dzakajairika dzinosanganisira kuwedzerwa, itsirwo, uye oxidation. Eteraifoti inosanganisira kuita cellulose neAlkyl mersides kana alkylene oxides pasi peAlkaline Mamiriro ezvinhu kuti aunze ether zvibodzwa. Kuwedzera, kune rumwe rutivi, kunosanganisira kuita cellucose ne carboxyylic acids kana acid anthydreides kuti aumbe ester ester zvibodzwa.

Iyo synthesis yemherem cellulose anaiters inoda kunyatso kutonga kwemamiriro ezvinhu ekuti uwane iyo yaunoda degree rekutsiva uye zvivakwa. Zvinhu zvakadai sekuita nguva, tembiricha, pH, uye CATALSSTS Tamba zvakajairwa mabasa mukutarisa kubudirira kweiyo synthesis maitiro.

4. Zvikumbiro zve Cellulose anaTers:

Cellulose anaiters inowana maInstruction-kubva kuSilitations kuyambuka maindasitiri akasiyana siyana nekuda kwezvivakwa zvavo zvinoitika. Muindasitiri yechikafu, vanoshandiswa senhau, stabilizers, uye emulsifiers mune zvigadzirwa senge sosi, soups, majasi, uye madhiragi. MetHyl Cellulose, semuenzaniso, inowanzoshandiswa seyakavharira uye binder mune zvigadzirwa zveBakery, ice creams, uye nyama analogs.

Muindasitiri yechechi yemishonga, cellaulose etana anoshandiswa kunge mabhasiketi, vanoparadza, uye vanodzora-vamiriri-vamiriri mukugadzira piritsi. HydroxyPropyl methyl cellel celler (HPMC), semuenzaniso, inoshandiswa zvakanyanya sedanda mukugadzirwa kwe piritsi nekuda kwezvakanakisa zvinosungirwa uye kuenderana nevamwe vezvimwe zvakanaka.

Mune indasitiri yekuvaka, cellulose ana anaiters inoshandiswa seyakawandisa mumasimendi uye mongororo yekuvandudza basa rekushanda, kuchengetwa kwemvura, uye kudedera zvivakwa. HydroxytHyl Cellulose (Hec), semuenzaniso, inowanzoshandiswa seyakakwenenzverwa uye nekuchengetwa kwemvura mumugodhi mumatanda ekumaodzanyemba, uye simende-yakavakirwa.

Muchiremba wezvemunhu uye cesmetics HydroxyPropyl Cellulose (HPC), semuenzaniso, inoshandiswa seyakavharwa mumiririri muzvikwereti zvechiremba

5. Zvizororo zvenguva yemberi nematambudziko:

Pasinei nekushandiswa kwavo kwakapararira uye kukosha kwavo mumaindasitiri akasiyana siyana, cellalose ana vana vanotarisana nezvimwe zvinonetsa, kusanganisira zvinetso zvezvakatipoteredza, zvinorambidzwa zvemamiriro ekunze, uye kukwikwidza kubva pane dzimwe nzira. Iko kushandiswa kwemheremellose ana ana vatambosiko kubva kune mamwe manhamba uye kukudziridzwa kwekuwedzera nzira dzeStntsis

Kupfuurirazve, kufambira mberi muNuzotechnology uye Biotechnology kune mikana mitsva yekugezesa uye kushandisirwa mhereta cellulose.

Mukupedzisa, cellulose eter anomiririra kirasi yezvinhu zvose yemakomputa neakasiyana-siyana maindasitiri akasiyana siyana. Zvivakwa zvavo zvakasarudzika, zvinosanganisira Solubility, viscosity, uye kugona kwemafirimu ekugadzira, ita kuti ivo vakwanise kudya, mishonga, kuvaka, uye zvigadzirwa zvekutarisira. Pasinei nematambudziko, akadai sekunetseka kwezvakatipoteredza uye zvinodzorwa zvakatipoteredza, cellulator zvinoramba zvichikonzeresa kuita basa rakakosha mukuwedzera mashandiro uye mashandiro emutengi manhamba uye maindasitiri ezvigadzirwa.
