Chii chinonzi sodium carboxymethyl cellelose?

Sodium CarboxyMethyl Cellerose (CMC) ishandare yaishandisirwa uye yakashandiswa zvakanyanya neyakajairika zvikumbiro zvemaindasitiri akasiyana siyana.

Nhanganyaya kuSodium CarboxyMethyl Cellulose (CMC)
Sodium carboxymethyl cellose, kazhinji yakajeka seCMC, inobva kune cellulose, imwe yeanonyanya kuwanda polyters pasi pano. Cellulose, inoumbwa nekudzokorora Glucose Units ne β (1 →) Glycossic Zvisungo, inonyanya kuwanikwa mumasero emaruva, ichipa rutsigiro rwechimiro. Inovandudzwa, bioderableable, uye isiri-ine chepfu, ichiita kuti ive chinhu chinotaridzika zvakaringana zvekushandisa zvakasiyana siyana zveindasitiri.

Chimiro uye zvivakwa
CMC iri kugadziriswa nekugadzirisa cellulose kuburikidza nemakemikari maitiro, apo hydroxyl mapoka pane cellucose backbone inotsiviwa neCarboxymethyl Mapoka (-Ch2-Cooh). Uku kutsiva kunopa mvura solubility uye yakavandudzwa zvivakwa kune cellulose, ichiita kuti iite yakakodzera kune yakasarudzika yakawanda yekushandisa.

Dhigirii rekutsiva Yakakwira DS Changes inokonzeresa mukuwedzera mvura solubility uye viscosity.

CMC inowanzo kuwanikwa seyakachena kusvika kune chena-chena poda, ine akasiyana-siyana saizi saizi zvichienderana nekunyorera kwayo. Izvo hazvina musoro, zvisina musoro, uye zvisiri zvepfu, zvichiita kuti ive yakachengeteka yekushandisa mune zvekudya uye zvigadzirwa zvemishonga. CMC yakagadzikana pasi pehuremu hwakawanda hwePP mamiriro uye kuratidzira zvakanakisa firimu-kugadzira zvivakwa.

Nzira dzekugadzira
Kugadzirwa kweCMC kunosanganisira matanho akati wandei:
Kugadzirira kweCellulose: Cellulose inowanzo kuvezwa kubva kune huni remapuranga, machira ekotoni, kana mamwe mafaera. Iyo cellulose inonatswa uye yakaputswa mumachira madiki kuti uwedzere maitiro ayo.

Eteraifitifitifitifiti yekuita: iyo yakacheneswa cellulose fibers inobatwa ne sodium hydroxide (naoh) kuti ivhure mapoka ehydroxyl. Saizvozvo, monochloroacetic acid (kana iyo sodium munyu) inowedzerwa kune yekuita musanganiswa wekusuma carboxymethyl mapoka kune iyo cellulose backbone.

Kusarerekera uye kugeza: Mushure mekuchinja kwetsika, chigadzirwa chinokonzeresa chakarerekera ne acid kuti ishandure muchimiro chengarava. Iyo CMC yasukwa kuti ibvise kusvibiswa uye ne-zvigadzirwa.

Kuomesa uye kugaya: Iyo yakacheneswa cmc yakaomeswa kubvisa yakanyanyisa kunyorova uye yakanyururwa kuti uwane iyo inodiwa saizi.

Mashandisiro andinoita
Sodium carboxymethyl cellose anowana akawanda ekushandisa maindasitiri akasiyana-siyana:
Indasitiri yeChikafu: CMC inozoshandiswa zvakanyanya sedhizimusi, stabilizer, uye kunyorovesa mumiririri mune zvigadzirwa zvekudya senge makirogiramu, zvakabikwa, uye zvipfeko. Iyo inovandudza maumbirwo, inodzivirira synesa, uye inowedzera muromo muromo mune zvekudya zvekudya.

Pharmaceutals: Mune iyo indasitiri inoshandiswa seyakagadzirwa sedanda mune piritsi mafomu, iyo viscosity modifier mumitsipa, uye lubricant mumhinduro dzeOfhthalmic. Iyo inovimbisa yunifomu inodhaka yekugovera uye kusunungurwa kwakadzorwa.

Zvigadzirwa zvega zvega: CMC inobatanidzwa mune zvigadzirwa zvega zvega se mazino, Shampoo, uye ganda rekugadzira semumiriri akakura, emulsifier, uye neyemumiriri wefirimu.

Indasitiri yepepa: Mune mapepa, CMC inowedzerwa kune yedhiramu mafomu ekuvandudza mapepa esimba, zvivakwa zvemusoro, uye kuchengetwa kwekuwedzera kwakadai semafirita uye dhayi. Izvo zvakare zvinosimudzira kudhiraji uye kuderedza guruva panguva yepepa kugadzirwa.

Industrale indasitiri: CMC inoshandiswa mukudhinda yekudhinda uye dhayi yekudyira seyakakwenenzverwa uye binder ye pigment pastes. Iyo inofambisa yunifomu yeruvara kuiswa uye inovandudza kupinza kwematare akadhindwa.

Mafuta negesi Indasitiri: CMC inoshandirwa mumvura inodhonza seViscotifier uye Fluid kurasikirwa kuderedza. Iyo inobatsira kuchengetedza borehole kugadzikana, kumisa solids, uye kudzora fluid rheology panguva yekudhirowa.

Indasitiri yekuvaka: Muzvinhu zvekuvaka zvakadai sedare, magirazi, uye zvigadzirwa zveGypsum, CMC inobatsira seyekuchengetwa kwemvura, kuvandudza kushanda uye kuderera.

Zvishatidziro uye zvigadzirwa zvekuchenesa: CMC inowedzerwa kune inodaira, vanochenesa, uye zvigadzirwa zvekuwachira seyekuchema senge mumiriri uye kusimbisa mumiririri. Iyo inosimudzira visikopa yemifananidzo yemvura uye inovandudza maitiro avo ese.

Kukurukurirana Kufunga
Sodium carboxymethyl cellose inowanzoonekwa seyakachengeteka (gras) yekushandisa mune zvekudya nemishonga yekuzvidzora neUS humbowo Nekudaro, zvakakosha kuti uve nechokwadi chekutevedzera zviyero zvakachena uye zvinoshandiswa zvinoshandiswa pakudzivirira chero mhedzisiro yakaipa.

Ipo CMC inoonekwa isina-ine chepfu, yakawandisa inhalation kana kumedza kweguruva zvimedu zvinogona kukonzera kutsamwisa uye gastrointar turakiti. Kubata kwakakodzera uye mari yekudzivirira pachako (ppe) inofanira kushandiswa panguva yekugadzira uye kubata maitiro.

Kukanganisa kwezvakatipoteredza
CMC inotorwa kubva kune inovandudzwa zviwanikwa, kunyanya inodyara-yakavakirwa cellulose, ichiita kuti ive isingaradziki biozo Iyo inoisa kusvibiswa kwe enzymatic nemineshuwa, pakupedzisira kuputsa muchinguvana muCarbon dioxide, mvura, uye biomass.

Nekudaro, maitiro ekugadzira eCMC anosanganisira maitiro emakemikari uye matanho esimba, ayo anogona kubatsira pakukanganisa kwezvakatipamhama senge simba, greenhouse gasi emission, uye chizvarwa chisina mvura. Kuedza kururamisa maitiro ekugadzira, kuwedzera simba rekubudirira, uye kuderedza marara kunogona kuderedza izvi zviitiko zvezvakatipoteredza.

Sodium CarboxyMethyl Cellerose (CMC) inzvimbo yakati wandei ine zvinyorwa zvakasiyana pane zvekudya, mishonga, machira, uye mamwe maindasitiri. Zvivakwa zvayo zvakasarudzika sedhiraivhi yemvura inoita kuti ive yakakosha mumamiriro akasiyana siyana, painenge ichishanda seanoshanda, stabilizer, binder, uye viscosity modifier.
