Hydroxyethyl methylcellulose (HEMC) waxay la mid tahay hydroxyethylcellulose (HEC) waxayna u adkaysataa cusbada badankeeda. Joogitaanka kooxaha methyl waxay abuurtaa dhaqdhaqaaqa dusha sare ee methyl cellulose dhexdhexaad ah iyo hydroxyethyl cellulose.

Astaamaha hydroxyethyl methyl cellulose
Hydroxyethyl Methyl Cellulose waa polymer ah non-ionic qaab budo cad ama off-cad, si fudud u milmi biyo qabow laakiin aan milmayn biyo kulul, xal waxay muujinaysaa pseudoplasticity xoog leh oo waxay bixisaa viscosity xiirid sare.HEMC waxaa inta badan loo isticmaalaa sida koolo, kolloid ilaalinta, dhumuc weyn iyo stabilizer iyo sidoo kale emulsification daro.

1. Solubility: ku milmay biyaha iyo qaar dareere organic ah. Waxaa lagu milmi karaa biyo qabow, diiraddeeda ugu sareysa waxaa lagu go'aamiyaa oo kaliya maqaar-ku-jirka, xuubka ayaa isbeddelaya viscosity, hoose ee viscosity, weynaanta milanka.
2. Cusbada iska caabbinta: alaabtu waa ether cellulose aan-ionic ahayn, mana aha electrolyte polymerization, markaa joogitaanka milixyada birta ah ama electrolytes organic, waxay ku xasilloon tahay xalalka aqueous, laakiin ku darida xad-dhaafka ah ee electrolytes waxay keeni kartaa gelation iyo roobab.
3. Dhaqdhaqaaqa dusha sare: Sababtoo ah xalka aqueous wuxuu leeyahay shaqada dhaqdhaqaaqa dusha sare, waxaa loo isticmaali karaa difaac kolloid ah, emulsifier iyo kala firdhiye.
4. Gelation Thermal: xal aqueous wax soo saarka marka la kululeeyo si heerkul gaar ah, noqdaan opaque, jel, formation of roobab, laakiin in qaboojinta joogto ah, waxa ay ku soo laabtay xaaladda xal asalka ah, iyo heerkulka at kaas oo gelation this iyo roobka dhacaa inta badan ku xiran tahay saliidaha ay, wakiilada joojinta, kolloid ilaalinta, emulsifiers iyo wixii la mid ah.
5. Dheef-shiid kiimikaad: dheef-shiid kiimikaad oo daciif ah iyo ur iyo dhadhan hooseeya, sababtoo ah ma metabolized iyo ur iyo dhadhan yar, sidaas darteed si weyn ayaa loogu isticmaalaa cuntada iyo daawada.
6. Caawinta caarada: Waxay leedahay caabbinta caariyaysi aad u wanaagsan iyo xasilloonida viscosity wanaagsan ee kaydinta muddada dheer.

Macluumaadka shirkadda

Waxyaalaha ay shirkadu soo dejiso iyo wax-soo-saarka dhoofinta ugu badan waxaa ka mid ah

(1) Qalabka cayriin ee dabiiciga ah ayaa si weyn loo isticmaalaa waxaana loo qaybin karaa saddex qaybood: mid waa alaabta ceeriin ee loo isticmaalo in lagu soo saaro alaabta kiimikada polymer, taas oo ah, monomer for polymerization; Midda kale waxaa loo isticmaalaa warshadaha kale ee kiimikooyinka organic, oo ay ku jiraan alaabta ceeriin ee alaabta kiimikada; Waxaa loo isticmaalaa dareerayaasha, qaboojiyaha, barafeeyaha, adsorbents gaaska, iwm. Kiimikada dabiiciga ah ee aasaasiga ah ayaa saldhig u ah horumarinta alaabada kiimikada ee kala duwan waana qayb weyn oo ka mid ah qaababka casriga ah ee warshadaha.

(2) Kiimikooyinka Batroolka: Kiimikada ka go'an ama laga soo qaatay batroolka ama gaaska dabiiciga ah Waxaa ka mid ah balaastikada, bacriminta, baakadaha, dharka, qalabka dhijitaalka ah, qalabka caafimaadka, saabuunta, taayirada iyo qaar kale oo badan. Waxa kale oo laga helaa qaybo badan oo ka mid ah nidaamka tamarta casriga ah, oo ay ku jiraan muraayadaha cadceedda, marawaxadaha dabaysha, baytariyada, kuleylka kulaylka ee dhismayaasha, iyo qaybaha baabuurta korontada.
