Qodista Saliidda darajada CMC
Qodista saliidda darajada CMC Sodium carboxymethyl celluloseis oo ka samaysan cellulose dabiiciga ah by wax ka beddelka kiimikaad ee biyo-milmi kara derivatives cellulose ether, waa muhiim ah ether cellulose biyaha-milmi, budo cad ama huruud ah, non-sun ah, dhadhan lahayn, waxaa lagu milmi karaa biyo, ayaa leh. xasilloonida kulaylka wanaagsan iyo caabbinta milixda, bakteeriyada. Dheecaanka slurry ee ay diyaarisay alaabtani waxay leedahay biyo-lumin wanaagsan, xannibaad iyo iska caabin heerkul sarreeya. Si weyn loo isticmaalo qodista saliidda, gaar ahaan biyaha cusbada Ceelasha iyo qodista saliidda badda.
Qodista saliidda darajada alaabada CMC waxay u qaybsamaan muuqalka sare (HV) iyo maangal hooseeya (LV), kuwaas oo ah alaabo tignoolajiyadeed sare leh oo leh xuquuqaha lahaanshaha garaadka madaxa banaan ee shirkada. Waxay ka tirsan tahay ether-ka anionic cellulose, waxayna leedahay sifooyin nadiifnimo sare leh, beddelaad heer sare ah iyo qaybinta lebbiska gao beddelka. Waxaa loo isticmaali karaa sida wakiilka dhumuc, regulator rheological, yaraynaysaa khasaaraha biyaha, iwm. CMC la viscosity sare iyo viscosity hoose leeyahay shaqo dhimis sifeynta heer sare ah ee labada dhoobo biyaha cusub iyo badda, iyo waa wax soo saarka lagama maarmaanka ah in waafaqsan dhoobada. CMC oo ay soo saartay shirkadeena waa badeecad si heer sare ah loo sifeeyay oo leh budo cad oo qulqulaya muuqaal ahaan iyo dareere viscous ah oo hufan oo ku jira xal aqueous ah.
Tilmaamaha alaabta
Carboxymethyl cellulose sodium cusbada waxaa inta badan loo isticmaalaa sida viscosity kordhaya iyo shaandhaynta wakiilka hoos u qodista dareeraha. Silsiladda molecular ee dheer ee carboxymethyl cellulose cusbada sodium waxay ku adkeysan kartaa qaybo badan oo dhoobo ah, waxay kordhisaa sibidhka keega dhoobada, waxay joojisaa balaadhinta fuuqbaxa dhogorta waxayna xoojin kartaa derbiga si fiican. Sodium carboxymethyl cellulose xal aqueous waxa uu leeyahay sifooyin badan oo aad u fiican iyo xasiloonida kiimikada, ma fududa in ay daxalka iyo metamorphic, dhib la'aan in ay badbaadada jireed, ganaax iyo emulsification deggan, adhesion wanaagsan iyo caabbinta milixda. Degenaansho wanaagsan oo saliidda iyo dareerayaasha organic.
(1) dhoobada ay ku jirto CMC waxay ka dhigi kartaa gidaarka ceelku inuu noqdo mid khafiif ah oo adag, keega filtarrada yareeya, si loo yareeyo khasaaraha biyaha.
(2) Ka dib marka lagu daro CMC dhoobada, daloolintu waxay heli kartaa awood hoose oo dhogorta bilawga ah, si ay dhoobadu u sahlanaato in la sii daayo gaasta ku duudduuban, qashinka si dhakhso ah ayaa loo tuuraa godka dhoobada ah.
(3) Qodista dhoobada, sida kala firdhisanaanta kale ee la hakiyey, waxay leedahay nolol cayiman, taas oo la dejin karo lana dheerayn karo iyadoo lagu daro CMC.
(4) dhoobada ay ku jirto CMC aad ayay u saamaysay caaryada sidaa darteed uma baahna in la ilaaliyo PH sare ama isticmaal waxyaalaha ilaaliya.
(5) Ka kooban CMC sida qodista dhoobada nadiifinta wakiilka daaweynta dareeraha, waxay iska caabin kartaa wasakhowga milixyada kala duwan.
(6) CMC oo ay ku jiraan dhoobo, xasillooni wanaagsan, xitaa haddii heerkulku ka sarreeyo 150 ℃ waxay weli yarayn kartaa khasaaraha biyaha.
Viscosity A sare, barokaca sare CMC ku haboon dhoobo leh cufnaanta hoose, halka viscosity hoose, barokaca sare CMC ku haboon yahay dhoobo cufnaanta sare. CMC waxay leedahay awoodda xakamaynta luminta biyaha sare, luminta sifeynta hufan, qiyaasta hoose, waxay xakameyn kartaa khasaaraha biyaha heer sare, iyada oo aan saameyn ku yeelan guryaha kale ee dhoobada; Iska caabbinta heerkulka wanaagsan, caabbinta milixda ee ugu fiican, gaar ahaan ku habboon qodista xeebaha iyo shuruudaha ceelasha qoto dheer ee qodista gaaska dabiiciga ah, qodista ceelka iyo mashaariicda kale. Sida kolloid-biyood qoto dheer oo ku jira nidaamka dhoobada qodista, waxa loo isticmaali karaa sida dareeraha dhimaya walaxda iyo wakiilka sii kordhaya viscosity.
Fqaybaha
(1) Si degdeg ah ugu milmay biyo qabow ama kulul;
(2) waxaa loo isticmaali karaa sida wakiilka dhumucdi, wakiilka xakamaynta rheological, koollada, xasiliye, kolloid ilaalin ah, wakiilka cayrinta iyo wakiilka biyaha;
Warshadaha ka faa'iidaysiga batroolka, CMC waa wakiilka daawaynta dhoobada qodida wanaagsan iyo diyaarinta walxaha dareeraha ah, heerka samaynta dheecaanka sare, caabbinta milixda wanaagsan. Heerka qodista saliidda CMC waa dareere lumis aad u wanaagsan oo yareeya dhoobada biyaha macaan iyo dhoobada biyaha badda ee dhoobada milixda leh, waxayna leedahay awood qaadis wanaagsan iyo iska caabin heerkul sare ah (150℃). Ku habboon diyaarinta dareeraha dhammaystirka brine cusub, biyaha badda iyo saturated brine, iyo miisaanka kalsiyum chloride waxaa loo qaabayn karaa cufnaanta kala duwan ee dareerayaasha dhamaystirka, iyo dhamaystirka viscosity dareeraha iyo luminta dareeraha hooseeya. Alaabadayada CMC-da ee muuqooda sare iyo viscosity hoose waxay la kulmaan heerka GB/T 5005, heerka OCMA Yurub iyo heerka API 13A.

Codsiga:
(1) Isticmaalka CMC ee dareeraha qodista.
CMC waxay ku habboon tahay in loo isticmaalo ka-hortagga iyo dhimista luminta dareeraha. Dareeraha slurry ee ay diyaarisay CMC waxay joojisaa kala firdhinta iyo ballaadhinta dhoobada iyo dhogorta ee warbaahinta milixda leh, taas oo xakameynaysa wasakheynta darbiga.
(2) Isticmaalka CMC ee dareeraha shaqada.
Dareeraha shaqada ee lagu diyaariyey CMC waa mid adag oo aan xannibin qulqulka aagga wax soo saarka sababtoo ah adkaha. Waxayna leedahay khasaare yar oo biyo ah, si ay biyaha lakabka wax-soo-saarka u yaraado, biyahana waxaa xannibi doona emulsion-ka waxayna sameeyaan ifafaale biyo-qabsi ah.
Dareeraha shaqada ee lagu sameeyay CMC waxa ay faa'iidooyin ka siisaa dareeraha kale ee shaqada.
Ka ilaali lakabka wax soo saarka waxyeelada;
Qaadista ceelka nadiifka ah iyo dayactirka ceelasha riigga ah oo yaraaday;
Waxay u adkaysataa galitaanka biyaha iyo dhoobada, oo marar dhif ah ayay finan soo baxaan;
Waxaa lagu kaydin karaa ama dib loogu isticmaali karaa ceel ilaa ceel qiimo jaban marka loo eego dareerayaasha shaqada dhoobada ee caadiga ah.
(3)Isticmaalkaee CMC ee dareeraha dillaaca.
Dareeraha dillaaca ee ay diyaarisay CMC waxay u adkeysan kartaa 2% KCI (waa in lagu daraa marka la diyaarinayo dareeraha dillaaca), waxay leedahay milmayn wanaagsan, waa ku habboon tahay in la isticmaalo, waxaa lagu diyaarin karaa goobta, oo leh xawaare xawli ah iyo ciid xoog leh oo qaadis ah. Way waxtar badan tahay marka loo isticmaalo qaababka cadaadiska osmotic ee hooseeya.
Baakadaha:
Alaabada CMC waxa ay ku xidhan tahay saddex bac oo xaashi ah oo ay ku jirto bac polyetylen ah oo gudaha ah oo la xoojiyay, miisaanka saafiga ahi waa 25kg kiishadiba.
