Carboxymethyl Cellulose:
Ioniccellulose etherinogadzirwa kubva kune yakasikwa machira (machira, etc.) mushure mekurapwa kweAlkali, vachishandisa sodium monochloroacetate se itstitification mumiririri wekuchinja, Dhigirii rekutsiva kazhinji kazhinji 0.4 ~ 1.4, uye kuita kwayo kwakanganiswa zvakanyanya neiyo degree rekutsiva.
.
. Kana tembiricha ichidarika 50 ° C, iyo viscosity haina kuchinjika.
(3) Kugadzikana kwayo kunokanganiswa zvikuru naPh. Kazhinji, inogona kushandiswa mune gypsum-based moturu, asi kwete mumutero-based moter. Kana alkaline yakawanda, icharasikirwa newiscosity.
(4) Kuchengetwa kwemvura kwayo kwakaderera pane iyo yemethyl cellulose. Iyo ine mari yekudzosera pane gypsum-based dours uye inoderedza simba rayo. Nekudaro, mutengo weCarboxyMethyl Cellerose akanyanya kuderera pane iyo ye methyl cellulose.
Cellulose alkyl ether:
Mumiriri anomiririra methyl cellelose uye ethyl cellulose. Mukugadzirwa kwemaindasitiri, methyl chloride kana ethyl chloride inowanzoshandiswa semumiriri wekuchinja, uye kuita kwacho kwakatevera:
Mune formula, r inomiririra Ch3 kana C2H5. Alkali constontration haingori chete neyero yekuziya, asi zvakare inokanganisa kushandiswa kweAlkyl Mersides. Iyo yakadzika iyo alkali yekusimbisa, iyo yakasimba iyo hydrolysis yeiyo alkyl halide. Kuti uderedze kushanduka kwekunyengedza mumiririri, iyo alkali yekushamwaridzana inofanira kuwedzerwa. Nekudaro, apo alkali yekushamwaridzana yakanyanya, yekuzvimba kwemasero yakaderedzwa, iyo isingakwanise kuita shanduko yekutsika, uye degree rekushatirisa rinodzikira. Nechinangwa ichi, chakatarisana nengozi kana solid liyo inogona kuwedzerwa panguva yekuita. Iyo yekugadzirisa inofanirwa kuve neyako yakanaka yekukurudzira uye yekubvarura mudziyo kuitira kuti Alkali inogona kugoverwa zvakanyanya.
Methyl cellulose inoshandiswa zvakanyanya seanonamata, inonamatira uye inodzivirira kuti ishandiswe embeu, chinyoreso chekudya, chinonamatira, chinonamatira, chinonamatira, chinonamira chezvinodhaka Chinyorwa, uye cheLoventx pendi, kudhinda ink, kugadzirwa kweCeramic, uye kusanganisa kuita simende kunoshandiswa kudzora nguva uye kuwedzera simba rekutanga, nezvimwe.
EtHyl Cellulose zvigadzirwa zvine yakakwirira mechaniki simba, kuchinja-chinja, kupisa kuramba uye kutonhora kuramba. Yakadzika-yakatsiva TEFYL Cellulose ine mvura uye Dilute Alkaline Solutions, uye zvigadzirwa zvakakwirira-zvakadzika zvinonyangadza mune yakawanda organic sol. Iyo ine kuwirirana kwakanaka neye dzakasiyana-siyana meso uye mapurasitiki. Inogona kushandiswa kugadzira mapurasitiki, mafirimu, mahuremu, maAnderives, latex uye anobatanidza zvinhu zvezvinodhaka, nezvimwe
Iko kusuma kwehydroxylk mapoka muCellulose Alkyl emaCelll vanorwadzisa, vanowedzera tembiricha yekuchinja, et. ratio ye alkyl kune hydroxylk mapoka.
Cellulose hydroyiylkyl ether:
Vamiriri vane hydroxythyl cellulose uye hydroxypruppropyl cellulose. Eteraginging vamiririri ndeye epoxides yakadai se ethylene oxide uye profilyo oxide. Shandisa acid kana chigadziko secatalyst. Kugadzirwa kwemaindasitiri ndiko kuita alkali cellulose neEtheralese mumiririri: HydroxytHyl Cellench Hydroxypruppropyl Cellulose ine yakakwira substitution kukosha inongova inongova mumvura inotonhora asi kwete mumvura inopisa. Hydroxethyl Cellulose inogona kushandiswa seyakavheneka kwejasi reLatex Iko kushandiswa kwehydroxypruppropyl cellulose kwakafanana neiyo yeiyo hydroxytlyl cellulose. HydroxyPropyl Cellulose neyakaderera substitution kukosha inogona kushandiswa seye mishonga yekuwedzera, iyo inogona kuve neese inosunga uye yekuvhara zvinhu.
Carboxymethylcellose, akapfupikiswa seCmc, zvinowanzorerwazve muchimiro chemunyu wemunyu. Iyo yekuzunza mumiririri ndeye monochloroacetic acid, uye kuita kwacho kwakatevera:
Carboxymethyl cellelose ndiyo inonyanya kushandiswa mvura-soluble cellulose ether. Munguva yakapfuura, yainyanya kushandiswa sematope anonakidza, asi iko zvino kwave kuchishandiswa sekuwedzera kweshanduro, kupfeka kwekadhibhodi yekadhibhodhi uye nepepa. mushonga, zino, uye zvakare sekunamatira kweCeramics uye kuumbwa.
Polyanionic cellulose (Pac) ndeye ioniccellulose etheruye yakakwira-yekupedzisira kutsiva chigadzirwa che carboxymethyl cellerose (cmc). Ichena, kubva-chena kana kuti yero-chena poda kana granule, isina chepfu, isina kugadzikana, inogadzirisa inogadziriswa, ine hutsinye kupokana nekudzika uye kupokana kwemunyu, uye zvinhu zvakasimba zveantiquage. Hapana nyoro uye kuora. Iyo ine maitiro ekuchena kwakanyanya, akakwira dhigirii rekutsiva, uye kugoverwa kwunifomu kwevatsidzike. Inogona kushandiswa seBinder, Thickener, Rheology Modifier, Fluid Loms Celler kugadzikana uye kusangana zvakakwirira kuita zvinodiwa.
Cyanoethyl Cellulose ndiyo yezvigadzirwa zvekuita cellulose uye acrylonitrile pasi peiyo cartalis yeAlkali:
Cyanoethyl Cellulose ane yakakwira dielectric inogara ichiramba uye yakaderera kurasikirwa uye inogona kushandiswa seye singin matrix ye phosphor uye magetsi magetsi. Yakadzika-yakatsiva Cyanoethyl Cellalose inogona kushandiswa sepepa rekusimbisa kweshanduko revashanduri.
Doro rakakwirira rakakwirira ersitty oters, Alkenyl rin'ters, uye vanonhuwira vanonhuhwirira zvavakatarwa, asi havana kushandiswa mukuita.
Nzira dzekugadzirira dze cellulose ether inogona kukamurwa kuita nzira yemvura yepakati, solvent nzira, iyo nzira yakasimba, iyo nzira yegedhi, iyo nzira yemifananidzo uye musanganiswa wepamusoro nzira.
