I-Carboxymethyl Cellulose (CMC)

I-Carboxymethylelylll (CMC) isithombe esifakiwe

Incazelo emfushane:

Njengamanje, ubuchwepheshe bokuguqulwa kwe-cellulose ikakhulukazi bugxila ekuthetheleni nasekuhlolweni. I-Carboxmetyltation uhlobo lobuchwepheshe bokuthenjwa. I-Carboxymethyl Cellulose (CMC) itholakala nge-carpuletylitation ye-cellulose, futhi isixazululo saso samanzi sinemisebenzi yokuqina, ukwakheka kwamafilimu, ukugcinwa komswakama, ukugcinwa komswakama, ukusetshenziswa kwezimboni kanye namaphepha nezinye izimboni. Kungenye yezitha ezibaluleke kakhulu ze-cellulose.

Ilungiselelwe kusuka kuma-cellulose derivativevents of carboxymethyl substitunts, ephathwe nge-sodium hydroxide ukwakha i-alkali cellulose, bese ephendula nge-monochlororometic acid. Uphiko lwe-glucose olwakha ama-cellulose anamaqembu amathathu angena esikhundleni se-hydroxyl, ngakho-ke imikhiqizo enamazinga ahlukene wokubuyiselwa esikhundleni angatholakala. Lapho i-1mmol carboxymelyl yethulwa ngesisindo se-1G eyomile ngokwesilinganiso, iyakhohlisa emanzini bese idonsa i-acid, kepha ingavuvukala futhi isetshenziselwe i-Ion Exchange Chromatography. I-Carboxymethyl Pka, cishe ama-4 emanzini amsulwa kanye ne-3.5 ku-0.5mol / l nacl, kuvame ukuhlukaniswa ngamanzi e-carboxymethyl, kungancishiswa ngamanzi ukwakha isixazululo esizinzile.

I-EverBright® 'LL futhi ihlinzeka ngezifiso: okuqukethwe / okumhlophe / izinhlayiya / phvalue / ukufakwa kombala / ukufakwa kwemininingwane / ukufakwa kwemikhiqizo ethile efanelekile ngezimo zakho zokusebenzisa, futhi zinikeze amasampula wamahhala.

Ukusetshenziswa Komkhiqizo

I-Carboxymethyl Cellulose (CMC) iyimpuphu engeyona enobuthi futhi engenambitha emhlophe enomdlandla ngokusebenza okuzinzile futhi kulula ukuncibilikisa emanzini. Isixazululo sayo samanzi asithathi hlangothi noma i-alkali esobala i-liquid, incibilika kwezinye izinamathiseli ezinamanzi nama-resins, kanye nokungabonakali kuma-organic solvents afana ne-ethanol. I-CMC ingasetshenziswa njenge-binder, isikhungo, i-ejenti yokumiswa, i-emulsifier, i-distrilifier, i-stabilizer, i-agentbox, njll.

Ukwehlisa

1. I-Sodium carboxyyl celtulose iyi-surfactant, engasetshenziswa njengokwakhiwa kabusha okulwa nokuhlanzeka, okuyinto ehlakazekile futhi evunyelwe yizinhlayiya zebala, zakha isendlalelo se-adsorption esiqinile sokuvimbela i-adpositption yayo.

2. Lapho kufakwa i-sodium carboxymethyl celtulose ku-washing powder, ikhambi lingasatshalaliswa ngokulinganayo futhi kalula ama-adsorbed ngaphezulu kwezinhlayiya eziqinile, akha ungqimba lwe-hydrophilic adsorption ezungeze izinhlayiya eziqinile. Lapho-ke ukungezwani okuphakathi koketshezi kanye nezinhlayiya eziqinile kungaphansi kwengxabano engaphezulu ngaphakathi kwezinhlayiya eziqinile, kanye nomphumela omanzi we-molecule eqinile. Lokhu kuhlasela ukungcola emanzini.

I-3. I-sodium carboxyyl celtulose yengezwa empuphure yokuhlanza, enomphumela wokugcizelela. Ngemuva kokugcizelela isilinganiso samafutha, akulula ukubuthana futhi kucace ngezingubo.

I-4. I-Sodium carboxyyl celtulose ingezwe empuphure yokuhlanza, enomphumela wamanzi futhi ingangena ezinkineni ezingcolile ze-hydrophobic, ichoboze izinhlayiya ezingcolile ibe izinhlayiya ezihlanganayo, ukuze ukungcola kube lula ukushiya i-fiber.

Isengezo sokudla

I-CMC isetshenziswa kabanzi embonini yokudla, eziphuzweni ezahlukahlukene zobisi, izinkokhelo, idlala indima yokuqina, ukuqina kanye nama-pastes, dlala indima, ukuthuthukisa amanzi, ukukhulisa ubulukhuni, ukuthuthukisa ubulukhuni nokunye. Phakathi kwazo, i-FH9, FVH9, FM9 ne-FL9 banokuqina okuhle kwe-acid. Imikhiqizo yohlobo oluphezulu oluphezulu inezakhiwo ezinhle zokuqina. I-CMC ingaxazulula ngempumelelo inkinga yokuhlukaniswa okuqinile okuwuketshezi kanye nemvula ye-lactic acid isiphuzo lapho okuqukethwe kwamaprotheni kukhulu kune-1%, futhi kungenza ubisi lwe-lactic acicias lube nokunambitheka okuhle. Ubisi lwe-lactic olukhiqizwa lungagcina ukuqina kuhlu lwe-PH lwe-3.8-4.2, lungamelana nenqubo yokuhlobisa kanye nenqubomgomo ye-135 Ukwakheka kokudla okunempilo okuqala nokunambitheka kweyogathi kuhlala kungashintshiwe. I-Ice Cream nge-CMC, ingavimba ukukhula kwamakristalu eqhwa, ngakho-ke i-ayisikhilimu inambitha kahle lapho idla, akukho okunamathelayo, okunamafutha, okusindayo futhi okunye ukunambitheka okubi. Ngaphezu kwalokho, izinga lokuvuvukala liphezulu, futhi ukumelana kwezinga lokushisa nokumelana nokuncibilika kulungile. I-CMC yama-noodle osheshayo yenza ama-noodle asheshayo anobunzima obuhle, ukunambitheka okuhle, ukwakheka okuphelele, ukulungiswa okuphansi kwesobho, futhi kunganciphisa futhi okuqukethwe kawoyela (cishe ama-20% aphansi kunokusetshenziswa komoya wokuqala).

Uhlobo lokuhlanzeka oluphezulu

Iphepha le-CMC Ibanga le-CMC lisetshenziselwa ukugcwaliswa kwamaphepha, ukuze iphepha linobukhulu obuphezulu, ukuvumela okuhle kwe-ink, kungathuthukisa ukunamathela phakathi kwemicu ngaphakathi kwephepha, ngaleyo ndlela kuthuthukise ukumelana nephepha nokugoqa. Thuthukisa ukunamathela kwangaphakathi kwephepha, ukunciphisa uthuli lokuphrinta ngesikhathi sokuphrinta, noma kungabikho uthuli. Indawo ephepheni ukuthola ukubekwa uphawu okuhle nokumelana kawoyela ukuthuthukisa ikhwalithi yokuphrinta. Ingaphezulu lephepha lithuthukisa i-lusterter, linciphisa i-poorter, futhi lidlala indima yokugcinwa kwamanzi. Kuyasiza ukuhlakaza i-pigment, yandise impilo ye-scraper, futhi inikeze i-fluidity engcono, izakhiwo ze-optical nokuguquguquka kokuphrinta kwezindlela zokuqukethwe eziqinile.

Ibanga lokuxubha amazinyo

I-CMC ine-pseudoplasticity enhle, i-thixotropy kanye nokuphuma ngemuva. Ukunameka kwezinyo amazinyo kuyazinza, ukuvumelana kufanelekile, ukwakheka kuhle, amazinyo angenawo amanzi, awakhethi, awonakalisi, abushelelezi, abushelelezi. Ukuhambisana okuhle ngezinto ezahlukahlukene eziluhlaza emabhokweni ezinyo; Ingadlala indima enhle ekubumbeni, ukubopha izibopho, okunomswakama nokulungisa amakha.

Ekhethekile ama-ceramics

Ngokukhiqizwa kwe-ceramic, asetshenziswa ngokulandelana kumbungu we-ceramic, glize passe kanye ne-floral glaze. I-Ceramic Ibanga CMC isetshenziswa njenge-binder engenalutho ku-ceramic billet ukuthuthukisa amandla nobukhulu be-billet. Thuthukisa isivuno. Ku-Curamic glaze, kungavimba imvukazi yezinhlayiya ze-glaze, ithuthukise amandla okunamathela kwe-glaze, ithuthukise ubuhlobo be-glaze engenalutho futhi ithuthukise amandla we-glaze ungqimba. Inokuvumela okuhle nokuhlakazeka esigcekeni sokuphrinta, ukuze i-gloze ye-phrinta iyenzile futhi iyunifomu.

Ekhethekile kawoyela

Inezici zama-molekyuli athambekelayo afanayo, ubumsulwa obuphezulu kanye nomthamo ophansi, ongathuthukisa ukusebenza kahle kwenqubo yodaka. Ukumelana nomswakama okuhle, ukumelana nosawoti kanye nokuphikiswa kwe-alkali, okulungele ukuhlanganiswa nokusetshenziswa kwamanzi agcwele kasawoti namanzi olwandle. Ilungele ukulungiswa kwe-powder kanye nesikhathi esifushane sokuqina ensimini yokuxhashazwa kawoyela. I-Polyanionic Cellulose (PAC-HV) iyi-viscosifier ephumelela kakhulu enesivuno esikhulu se-pulp kanye nekhono lokunciphisa ukulahleka kwamanzi odakeni. I-Polyanionic Cellulose (i-PAC-LV) iyinhlangano elahlekayo ehle kakhulu ka-fluid odakeni, enokulawulwa okuhle ngokukhethekile kokulahleka kwamanzi kudaka lwamanzi olwandle nodaka lwamanzi agcwele. Ilungele uhlelo lodaka olunzima lokulawula okuqukethwe okuqinile nobubanzi boshintsho. I-CMC, njenge-gel ecashile uketshezi, inezici ze-gelatiness enhle, isihlabathi esinamandla, umthamo wokuphuka kwenjoloba kanye nezinsalela eziphansi.
