Iimpawu zesicelo kunye neemfuno zenkqubo ye-CMC ekutyeni

I-Sodium Carboxymethyl Selelose, ekubhekiselwe kuyo njenge-carboxymethyl selulose (CMC) luhlobo lwe-fiber ye-fiber ephezulu elungiselelwe ngokutshintsha kweekhemikhali kwe-selupose yendalo. Ubume bayo yiyunithi ye-D-GLucose ye-D-GLucose nge-β (1 → 4) Glycossidic Box. Ukusetyenziswa kwe-CMC kuneengenelo ezininzi kunabanye amanzibhu.

01
I-CMC isetyenziswa ngokubanzi ekutyeni

(1) I-CMC inozinzo oluhle

Ngokutya okubandayo njengama-Possicles kunye ne-ice cream, inokulawula imilinganiselo yokwandiswa kwaye igcine isakhiwo sokwandiswa kwaye sigcine inyibilike, inyibilike icocekile, kwaye icocekile umbala.

Kwiimveliso zobisi, nokuba lubisi olunencasa, ubisi lweziqhamo okanye ubisi lweziqhamo okanye i-yogurt, inokusabela ngeprotheyini yexabiso le-SOLKIRT

(2) I-CMC inokudityaniswa kunye nezinye izinto zokuzinzisa kunye ne-emulsiber

Kwimveliso yokutya nakwiziselo, abavelisi ngokubanzi basebenzisa iindlela ezahlukeneyo zokuzinza, ezinjenge-Gantan Gum, i-Guart Gulsisher, njl njl.

(3) I-CMC ine-pseudeoplastice

Uhlobo lwe-CMC lwe-CMC luyijwilikile kubushushu obahlukeneyo. Njengoko iqondo lobushushu liyaphuma, ukubonwa kwesisombululo kuyancipha, kwaye ngokuchaseneyo; Xa amandla eShear ekhoyo, uVekkosity weCMC uya kuncipha, kwaye ngokunyuka kwamandla eshishi, i-vickosity iya kuncipha. Ezi mpahla zenza ukuba i-CMC ikwazi ukunciphisa umthwalo wesixhobo kunye nokuphucula ukusebenza kwe-homonistion xa ivuselela, i-homogening, i-homogesing, kunye nokuhamba kweminye imibhobho.

02
Iimfuno zenkqubo

Njengomntu onesitayile esisebenzayo, i-CMC iya kuchaphazela isiphumo sayo ukuba isetyenziswe ngokungafanelekanga, kwaye ibangele ukuba imveliso ikhutshiwe. Ke ngoko, kwi-CMC, kubaluleke kakhulu ngokupheleleyo kwaye ngokugqibeleleyo ukusasaza isisombululo sokuphucula ukusebenza kwawo, ukunciphisa imithamo, ukuphucula umgangatho kunye nokwandisa isivuno. Ngokukodwa, ingqalelo kufuneka ihlawulwe kwinqanaba ngalinye lenkqubo:

(1) Izithako

I-1. I-Sheard-Sheed-Sheed Sheartion Inkqubo yokusasazeka kwamandla

Zonke izixhobo zokudibanisa ubuchule zinokusetyenziselwa ukunceda i-CMC ukusasaza emanzini. Ngokuhamba ngesantya esiphezulu, i-CMC inokufakwa emanzini ukukhawulezisa ukupheliswa kweCMC.

Abanye abavelisi njengangoku basebenzisa abaxube ngemigubo yomgubo wamanzi okanye iitanki ezihamba ngesantya esiphezulu.

I-2. Iswekile eyomileyo yokuxubanisa ukusasazeka

Hlanganisa kakuhle nge-CMC kunye neswekile ekhutshiweyo kumyinge we-1: 5, kwaye uyitshize kancinci phantsi kwe-CMC.

3. Inyibilikisiwe kumanzi aneswekile

NjengeCaramel, njl njl., Inokukhawulezisa ukutshitshiswa kwe-CMC.

(2) ukongezwa kwe-acid

Kwezinye ii-acidic, ezinjengeYogathi, iimveliso ezinganyangekiyo ze-acid kufuneka zikhethwe. Ukuba basebenza ngokwesiqhelo, umgangatho wemveliso unokuphuculwa kwaye ukuphakama kwemveliso kungathintelwa.

1. Xa wongeza i-ACID, iqondo lobushushu le-Acid kufuneka lilawulwe ngokungqongqo, ngokubanzi ≤20 ° C.

2. Ingcinezelo ye-acid kufuneka ilawulwe nge-8 ukuya kwi-20%, iphantsi engcono.

I-3. I-ACID ACD ACDUSTAY Indlela yokutshiza, kwaye yongezwa ecaleni kwendlela yokwenyani yomyinge wezithoko, kangangemizuzu eyi-1-3.

I-4. Isantya se-slide n = 1400-2400r / m

(3) homogeneous

I-1. Injongo yokwahlulwa

I-homogeneous, inamafutha enamafutha, i-CMC kufuneka idityaniswe ne-ersisifier, efana ne-monoglycer, i-homoning the monogides yi-18-25MPA, kwaye iqondo lobushushu lingama-60-70 ° C.

I-2. Injongo ye-Wakenti

I-homogesization, ukuba izithako ezahlukeneyo kwinqanaba lokuqala alifani ngokupheleleyo, kusekho amasuntswana amancinci, kufuneka ukuba i-homogensed, i-homogensed, uxinzelelo lwe-homoning yi-60-70 ° C.

(4) I-Sterilization

I-CMC kubushushu obuphezulu, ngakumbi xa iqondo lobushushu liphezulu kune-50 ° C ixesha elide, i-viscosity ye-CMC enomgangatho ophantsi wonqumla ngokungahambi kakuhle. Uhlobo lwe-CMC lwabavelisi ngokubanzi luya kwehla nzulu nge-80 ° C kangangemizuzu engama-30, ke ngokukhawuleza ukubulala intsholongwane okanye i-facisocing inokusetyenziswa. Indlela yokubulala intsholongwane yokuphelisa ixesha le-CMC kubushushu obuphezulu.

(5) Eminye iMpahla

I-1. Umgangatho wamanzi akhethiweyo kufuneka ucoceke kwaye unyangwe amanzi empompo kangangoko kunokwenzeka. Amanzi amqumkele akufuneki asetyenziselwe ukosuleleka kwentsholongwane kwaye ichaphazele umgangatho wemveliso.

2. I-tinss yokuphelisa nokugcina i-CMC ayinakusetyenziswa kwizikhongozeli zensimbi, kodwa izikhongozeli zentsimbi ezingenasiphelo, izitya zokhuni, okanye izikhongozeli ze-ceran, okanye izikhongozeli ze-ceran, okanye izikhongozeli ze-ceran. Thintela ukungafihli ii-ions zentsimbi.

I-3. Emva kokusetyenziswa nganye nganye ye-CMC, umlomo webhegi yokupakisha kufuneka uboshwe ngokuqinileyo ukuthintela ukuthathwa komswakama kunye nokuwohloka kwe-CMC.

Ingayichitha njani ngokukhawuleza? Ngamanye amaxesha, emva kokubila, iyanyibilika kancinci.

Phendula:
Hlanganisa nezinye iicolloids, okanye ukusasazeka nge-1000-1200 ye-RPM Agitotor.

Ukusasazeka kwe-CMC akulunganga, i-hydrophility ilungile, kwaye kulula ukudibanisa, kwaye iimveliso ezinomda ophezulu obambeleyo ziyabonakala ngakumbi! Amanzi afudumeleyo ayanyibilika ngokukhawuleza kunamanzi abandayo. Ukubila ngokubanzi akucetyiswanga. Ukupheka kwexesha elide kweemveliso ze-CMC kuya kutshabalalisa ulwakhiwo lwe-molekyuli kwaye imveliso iya kuphulukana ne-viscofity!
