Kukonzeresa simba re cellulose ether

Cellulose etanaIboka revadzidzi vanoverengera vanoshandiswa zvakanyanya muindasitiri akasiyana siyana nekuda kwezvivakwa zvavo zvakashata. Kutanga neSumo kuCellulose ema cellulose, iyi bepa rinodzora mumuchina kuseri kwemhedzisiro yavo, kusimbisa kuti kubatana nemamolekyudhi emvura kunotungamira sei kuwanda kwekuvandudzwa kwekusimbisa kwevasungwa. Mhando dzakasiyana-siyana dze cellulose anaiters dzinokurukurwa, kusanganisira methyl cellulose, hydroxyprEpyl cellever, uye carboxymelosel cellelose, imwe neimwe ine hunhu hwakasiyana hunhu. Zvikumbiro zve cellaulose anaitha mumaindasitiri akadai sekuvaka, mishonga, chikafu, chengetedzo, zvichiratidza basa ravo rekuita muzvigadzirwa zvechigadzirwa uye maitiro ekugadzira. Chekupedzisira, kukosha kwe cellulose aungana mumaindasitiri emazuva ano kunosimbiswa, pamwe chete nehanya yemangwana uye nguva yemberi uye nguva yemberi muCellulose ether tekinoroji.

Cellulose ana ana vana verimwe kirasi yePolymers inotorwa kubva kuCellulose, ubiquitous biopolose madziro inowanikwa mumasango masero emadziro. Nezvakasarudzika physicochemical zvivakwa, cellaulose anaither inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana, kunyanya nekuda kwekuita kwavo kwakasimba. Kugona kwemheremellose ana ana ana manyombe kuti uwedzere zvivakwa uye nekuvandudza zvivakwa zvozvinyorwa kunovaita kuti vazive mukushandisa kwezvinhu zvekushandisa kubva kune zvekuvaka zvinhu kune mishonga yemishonga.

1.Zviratidzo zvema cellulose etana

Usati waneta mumhedzisiro yemasero e cellulose eva Cellulose. Izvo zvakakosha kuti unzwisise zvivakwa zvavo zvekugadzira. Cellulose ana ana vana yakashongedzwa kuburikidza nemakemikari kugadziridzwa kwemheremalose, kunyanya inosanganisira maitiro ekuchinja. Iyo hydroxyl mapoka (-OOH) aripo muCellulose Backbone ari pasi pekutsiva pamwe neEther mapoka (-or), kupi r-gadziriro dzakasiyana siyana. Ichi chinjanje chinotungamira kuzvinhu zvekuchinja mumanyorerwo uye zvivakwa zve cellulose, kuendesa hunhu hwakasiyana kune cellulose ana vana.

Iyo yekugadziridzwa kwechimiro mu cellulose ana ana vanayo vanopesvedzera yavo yekubatanidza, maitiro ezvinyorwa, uye zvinhu zvakakora. Dhigirii rekutsiva Yakakwira DS kazhinji inogadzirisa nekuwedzera kwekuwedzera kwekunyora uye kurerutsa kushanda.

2.Mechanisiss yekukakavara

Mhedzisiro inoshora yakaratidza ne cellulose ana ana vana kubva mukudyidzana kwavo nemamolekyudhi emvura. Panoparadzirwa mumvura, cellulose ethsologo hydration, mune morekuru emvura inogadzira hydrogen zvisungo neye ether emaono echeni uye hydroxyl mapoka emaketani emapolymer. Iyi nzira yekudyira inotungamira mukuzvimba kwemherem cellulose ether zvidimbu uye kuumbwa kwechimiro chechitatu-chakanangana network mukati mekasikati.

Iko kurambidzwa kwehydrated cellulose ether cheni uye kuumbwa kwehydrogen zvisungo pakati pePolymer mamorekuru vanopa kuVolymer vanowedzera kuwedzerwa kweVaKollenity. Pamusoro pezvo, kurudziro yemagetsi pakati pezvisina kukodzera ether mapoka Erther mamwe mapoka ezvekuwedzera AIDS mukudzivirira nekudzivirira pedyo nekurongedza kwePolymer ngetani uye kusimudzira kupararira mune solvent.

Maitiro eReological e Cellulose Ether Solutions anokurudzirwa nezvinhu zvakadai sePolymer Kusvirana, degree rekutsiva, rinorema, uye tembiricha. Pakukwenenzverwa, cellulose ether mhinduro dzeNewthibibitaan maitiro, nepo pakakwirira, ivo vanoratidza pseudoplastics kana dura-rekufungidzira maitiro nekuda kwekuvhiringidza kwePolymer.

3.Types of cellulose ana
Cellulose ana eter inosanganisira huwandu hwakasiyana-siyana hwerudzi rwezvakadzika, kupa chimwe nechimwe chakasiyana chinongedzo chakakora chakakodzera kune dzakasiyana siyana application. Mamwe marudzi anowanzo shandiswa e cellulose aungana anosanganisira:

MetHyl Cellulose (MC): Methyl Cellalose inowanikwa neEnthing of cellulose ine methyl mapoka. Izvo zvinonyangadza mumvura inotonhora uye inoumba pachena, viscous mhinduro. MC inoratidza yakanakisa mvura yekuchengetwa kwemvura uye inowanzoshandiswa seyakanyanya mumidziyo yekuvaka, majasi, uye zvigadzirwa zvekudya.

HydroxytHyl Cellulose (Hec): HydroxytHyl Cellulose is Synthesi

Zed nekuunza hydroxytHyl mapoka kune iyo cellulose backbone. Izvo zvinonyangadza mumvura inotonhora uye inopisa uye inoratidzira maitiro epseudoplastic maitiro. HEC inoshandiswa zvakanyanya mune mishonga yemishonga, zvigadzirwa zvega zvega, uye seanotenderera muLatex pendi.

Hydroxypropyl Cellulose (HPC): HydroxyPropyl Cellalose yakagadzirirwa neKutendeti yakagadzirirwa Cellulose ine hydroxyprospropropyl mapoka. Izvo zvinonyangadza mumhando dzakasiyana-siyana, kusanganisira mvura, doro, uye organic sol sol. HPC inowanzo shandiswa seyakakwenenzverwa, binder, uye mumiririri-emafirimu anogadzira mumishonga yemishonga, cosmetics, uye jasi.

CarboxyMethyl Cellerose (CMC): CarboxyMethyl Cellerose inogadzirwa neCarboxyMethylation yeCellulose ine Chloroacetic acid kana yayo sodium munyu. Iyo inonyura kwazvo mumvura uye inogadzira viscous mhinduro neyenzvimbo dzakanaka pseudoplastic maitiro. CMC inowana akawanda mafomu ezvigadzirwa zvezvikafu, mishonga yemishonga, zvinyorwa, uye kugadzira pepa.

Aya maCellulose eter inoratidza zvakaringana zvakakora, uye kuwirirana nezvimwe zvinoshandiswa, zvichiita kuti vakwanise kuita zvishandiso zvakasiyana-siyana maindasitiri.

4.Application of cellulose ana
Zvivakwa zvakasiyana-siyana zvinokakavara zve cellulose eter eva vanozvipira sevakakosha mune dzakasiyana siyana maindasitiri ekushandisa. Zvimwe zvakakosha zvikumbiro zvemaserulose aungana zvinosanganisira:

Zvivakwa zvekuvaka: Cellulose ana ana vanayo vanoshandiswa zvakanyanya seanowedzera muzvimende zvakadai sevhu, kurambidza, uye plaster kuvandudza basa, kuchengetwa kwemvura, uye kudedera. Ivo vanoita senge rheology modifiers, kudzivirira kusarongeka uye kuvandudza mashandiro ezvigadzirwa zvekuvaka.

Mishonga: Cellulose anaiters inowana zvinoshandiswa pakuratidzira mumishonga yemishonga sezvikwangwani, zvinoparadza, uye madhiri akakora mumapiritsi, macaples, uye mhinduro, uye mhinduro. Ivo vanovandudza iyo inoyerera zvivakwa zve poweders, inofambisa piritsi kumanikidzwa, uye kudzora kusunungurwa kwezvinhu zvinoshanda.

Zvigadzirwa zvekudya: Cellulose ana anawanhi vanowanzo shanda sekuremerwa, kusimbisa, uye magweta ane huwandu hwezvigadzirwa zvekudya, kusanganisira masaga, madhiri, uye zvigadzirwa zvemukaka. Ivo vanokwazisa chimiro, viscosity, uye muromo uchivandudza shefu kugadzikana uye kudzivirira synesa.

Cosmetics uye neyako hanya: Cellulose ana ana ana inoshandiswa mune cosetics uye zvigadzirwa zvega zvakadai semakiromita, limpons, shampoos, uye mazino, uye vamiriri vemafirimu. Ivo vanopa zvivakwa zvinodikanwa zvechiratidzo, kusimudzira kugadzikana kwechigadzirwa, uye zvinopa chimiro chakatsiga, chakasarudzika.

Pendi uye majasi:Cellulose etanaShumirawo se rheology modifiers mukupenda, majasi, uye anomiririra, kugadzirisa kudzora kweViscosity, Sag kuramba, uye kuumbwa kwemafirimu. Ivo vanopa mukana wekugadzikana kwembiru, kudzivirira pigment kugadzirisa, uye kuwedzera mashandisiro ekushandisa.

Mhedzisiro inoshora yemasero ye cellulose anaiters inoita basa rakakosha mumigwagwa yakasiyana-siyana yemaindasitiri uye zvigadzirwa zvigadzirwa. Zvivakwa zvavo zvechiratidzo zvetsiva, kuenderana nezvimwe zvinoshandiswa, uye biodergradability zvinoita kuti vafarire sarudzo kune vagadziri vezvikamu zvakasiyana siyana. Sezvo maindasitiri anoramba achiisa pekutungamira uye eco-oushamwari mhinduro, kudiwa kwe cellulose ana ana anait vanotarisirwa kumuka.
