MHEC loo isticmaalo saabuunta

Methyl Hydroxyethyl Cellulose MHEC la isticmaalaygudahasaabuunta ,gaar ahaanwaxaa loo isticmaali karaa dawada cadayga, shaambada, qubeyska, gacmo nadiifiyaha iyo kabo nadiifinta kiimikooyinka maalinlaha ah, dhumucda, ka hortagga saamaynta dejinta.

MHECwaa badeecad la mid ah oo lehkarboksimethyl cellulose CMC, ethyl cellulose EC, hydroxypropyl cellulose HPC, methyl hydroxyethyl cellulose MHEC, methyl hydroxypropyl cellulose MHPC, hydroxyethyl cellulose HEC. Hydroxyethyl cellulose ether ee alaabtan ee goobta codsiga kiimikada maalinlaha ah waa saameynta ugu fiican. Waa maxay sababta?KimaCellwaaxda tignoolajiyada si ay u sameyso sharraxaadda soo socota.

Kiimikada maalin walba gaar ahMHEC MH200MS viscosityMethyl Hydroxyethyl Cellulosewaa caddaan ama wax yar oo leh budo yar oo huruud ah, iyo ur aan lahayn, dhadhamin, aan sun ahayn. Waxay ku milmi kartaa biyo qabow iyo isku dhafka organic ee dareerayaasha, samaynta xal muuqda oo hufan. Xalka aqueous wuxuu leeyahay dhaqdhaqaaqa dusha sare, daahfurnaanta sare, xasilloonida xooggan, milanka biyaha ma saameynayso pH. Heerka kiimikaad ee maalinlaha ahMethyl Hydroxyethyl Celluloseshaambada, dhumucda jelka qubeyska, saamaynta barafka ka hortagta, timaha, xajinta biyaha maqaarka iyo filim wanaagsan. Iyada oo kor u kaca alaabta ceeriin ee aasaasiga ah, cellulose (qashin-qashin-qaboojiye) ayaa loo isticmaali karaa shaambo iyo jelka qubeyska qiimo jaban oo weli lagu gaaro natiijooyin la jecel yahay. Laga soo bilaabo xasiloonida iyo waxqabadka aasaasiga ah, HEC waxay ka fiican tahay alaabta kale ee codsiga alaabta kiimikada maalinlaha ah.

Methyl Hydroxyethyl Cellulose MHECsida surfactant aan-ionic ah. Waxay leedahay hawlaha dhumucyada, hakinta, isku xidhka, sabaynta, samaynta filimada, kala firdhinta, haynta biyaha iyo bixinta kolloid ilaalin ah. Guryahaan, gaar ahaan ilaalinta kolloidka iyo saamaynta biyo-haysashada. Aad ayey muhiim u tahay adeegsiga maalinlaha ah ee kiimikada.

viscosity gaar ah heerka kiimikaad maalin kastaMHEC200,000S oo ku milmay biyo kulul iyo qabow, guud ahaan aan lagu milmi karin inta badan dareerayaasha organic. Heerkulka sare ama karkarinta ma soo da'do, taasoo siinaya noocyo kala duwan oo milmayn iyo sifooyinka viscosity. Iyo gelation aan kulayl ahayn. Saamaynta dhumucda dambe aad bay u yar tahay.MHECaad ayuu u deggan yahay.

Methyl Hydroxyethyl Celluloseether ee berrinka codsiga kiimikada maalinlaha ah, sababtoo ahMHECwuxuu leeyahay waxqabadka sare ee ugu fiican, oo si ballaaran loo isticmaalo sida dhumuclaha, emulsifier iyo binder ee daruuraha maalinlaha ah, marka la isticmaalo, guud ahaan lagu milmo khamriga hooyada, diyaarinta khamriga hooyada, waa inay noqotaa habka isku dhafkaMHECshaandho ku shub biyo cayiman, majarafad iyo daadin. Ha joojin walaaqda ilaa dareeraha hooyadu uu nadiif yahay oo siman yahay. Ha ku darin walxaha kale, si aysan u saameynin nidaamka PH qiimaha. Waxa aad rabtaa in aad si fiican u wanaajiso tayada alaabta Waxaa la soo jeediyay in la kordhiyo heerkulka iyo qiimaha PH ee nidaamka si habboon.
