Sodium carboxymethylcellulose ruzivo

Sodium carboxymethylcellulose (NaCMC) inoshandiswa zvakasiyana-siyana uye inoshanda zvakasiyana-siyana cellulose kubva iyo inowana kushandiswa mumaindasitiri akasiyana siyana nekuda kwekusiyana kwayo. Mushonga uyu unotorwa kubva ku cellulose, polima yemusikirwo inowanikwa mumadziro esero rezvirimwa. Sodium carboxymethyl cellulose inogadzirwa nekuita cellulose ine sodium monochloroacetate uye kuita neutralizing iyo. Zvigadzirwa zvinobuda zvine huwandu hwezvinhu zvinodikanwa, zvichiita kuti zvive zvakakosha muchikafu nezvinwiwa, mishonga yemishonga, zvekuzora, machira nezvimwe.

Chimiro uye chimiro:

Sodium carboxymethyl cellulose i polymer inonyungudika nemvura ine mutsara chimiro. Iyo cellulose musana inogadziridzwa nemapoka ecarboxymethyl akaunzwa ne etherification. Iyo dhigirii yekutsiva (DS) inoreva huwandu hweavhareji yemapoka ecarboxymethyl pane anhydroglucose unit mucheni ye cellulose. DS inokanganisa zvakanyanya muviri uye makemikari zvimiro zveNaCMC.

Manufacturing process:

Kugadzirwa kwe sodium carboxymethylcellulose kunosanganisira matanho akati wandei. Cellulose inowanzo torwa kubva muhuni pulp kana donje uye inofananidzirwa kubvisa tsvina. Iyo inobva yaita ne sodium monochloroacetate pasi pemamiriro ealkaline kuunza boka re carboxymethyl. Chigadzirwa chinoguma hachina kusimba kuti uwane iyo sodium munyu fomu ye carboxymethylcellulose.

Zvenyama nemakemikari zvivakwa:

Solubility: NaCMC inonyanya kunyungudika mumvura, ichigadzira yakajeka uye viscous mhinduro. Kunyungudika uku ndiko hunhu hunokosha hwekushandiswa kwayo kwakapararira mumaindasitiri akasiyana.

Viscosity: Iyo viscosity ye sodium carboxymethylcellulose mhinduro inogona kugadziridzwa nekudzora dhigirii rekutsiva uye kuisa pfungwa. Ichi chivakwa chinoita kuti ive yakakodzera kune maapplication anoda kukora kana gelling.

Kugadzikana: NaCMC inoramba yakagadzikana pamusoro pehupamhi pH renji, iyo inosimudzira mashandiro ayo mune akasiyana mafomati.

Firimu-kuumba: Iine firimu-inogadzira zvinhu uye inogona kushandiswa kugadzira mafirimu uye machira mumhando dzakasiyana dzekushandisa.

application:

Indasitiri yeChikafu neChinwiwa:

Thickening agent:NaCMC inowanzo shandiswa seyakakora muzvigadzirwa zvekudya senge sosi, madhirezi uye zvinwiwa.

Stabilizer: Inobayainomisa emulsions uye kumiswa muzvigadzirwa zvakaita seaizikirimu uye saradhi madhirezi.

Texture Improve: NaCMC inopa inodiwa mameseji kune chikafu, ichivandudza hunhu hwazvo hwese.mushonga:

Binders: Yakashandiswasezvisungo mukugadzirwa kwehwendefa kuti tive nechokwadi chehutano hwemahwendefa.

Viscosity modifier: inogadzirisa iyo viscosity yegadziriro yemvura kubatsira kuendesa zvinodhaka.

Cosmetics uye kutarisirwa kwevanhu:

Stabilizers: Inoshandiswa kudzikamisa emulsions mumakirimu uye lotions.
Thickeners: Wedzera viscosity ye shampoo, mushonga wemazino uye zvimwe zvigadzirwa zvekuchengeta wega.
textile:

Sizing agent: inoshandiswa kugadzira machira kuvandudza kusimba uye kutsetseka kwemafiber panguva yekuruka.

Kudhinda paste: Inoita seyakakora uye rheology modifier mune machira ekudhinda paste.
Indasitiri yeOiri neGasi:

Drilling fluid: NaCMC iririnoshandiswa setackifier mumvura yekuchera kuti iwedzere rheological properties.

Indasitiri yemapepa:

Coating agent: inoshandiswa kupfekedza mapepa kuvandudza zvivakwa zvepasi.
imwe indasitiri:

Kurapa Kwemvura: Inoshandiswa mumagadzirirwo emvura nekuda kweiyo flocculation zvivakwa.

Detergent: Inoshanda seyakagadzika mune mamwe magadzirirwo ekuchenesa.

Kuchengetedzwa nemitemo:

Sodium carboxymethylcellulose inowanzo zivikanwa seyakachengeteka (GRAS) yekushandisa mukudya nemishonga yekushandisa. Inopindirana nemirairo uye zvakatemwa zvakatemwa neakawanda masangano, kusanganisira iyo US Food and Drug Administration (FDA) uye European Chikafu Safety Authority (EFSA).

Sodium carboxymethyl cellulose i polymer inoshanda yakawanda ine huwandu hwakawanda hwekushandisa mumaindasitiri akasiyana. Kusanganiswa kwayo kwakasiyana-siyana kwekunyungudika, viscosity control, kugadzikana uye firimu-kugadzira zvinhu zvinoita kuti ive chinhu chinokosha mumhando dzakasiyana-siyana. Sezvo indasitiri iri kuramba ichishanduka, kudiwa kwesodium carboxymethylcellulose kungangoenderera nekuda kwekuita kwayo kwakasiyana-siyana uye kubatsira mukuvandudza kushanda kwechigadzirwa mumashandisirwo akasiyana.
