Saabuunta darajada HEMC
Saabuunta darajada HEMCHydroxyethyl methylcellulose waa ur aan ur lahayn, dhadhamin, budo cad oo aan sun ahayn oo lagu milmi karo biyo qabow si loo sameeyo xal hufan. Waxay leedahay sifooyinka dhumuc, isku-xidhka, kala firdhinta, emulsification, samaynta filimka, joojinta, adsorption, gelation, dhaqdhaqaaqa dusha sare, xajinta qoyaanka iyo kolloid ilaalinta. Maadaama xalka aqueous uu leeyahay shaqada firfircoon ee dusha sare, waxaa loo isticmaali karaa kolloid ilaalin ah, emulsifier iyo kala firdhiye. Hydroxyethyl methyl cellulose aqueous aqueous ayaa leh biyo nadiif ah oo wanaagsan waana wakiil biyo celin wax ku ool ah.
Saabuunta darajada HEMCHydroxyethylMethylCiloseWaxaa loo yaqaan Methyl Hydroxyethyl Cellulose (MHEC), Waxaa lagu diyaariyay soo bandhigida beddelka ethylene oxide (MS 0.3).~0.4) galay methyl cellulose (MC). Dulqaadkeeda milixda ayaa ka fiican kan polymers-ka aan la beddelin. Heerkulka jel ee methyl cellulose sidoo kale wuu ka sarreeyaa kan MC.
HEMC ee darajada saabuunta waa budo cad ama wax yar oo huruud ah, waana mid aan ur lahayn, dhadhamin oo aan sun ahayn. Waxay ku milmi kartaa biyo qabow iyo dareerayaasha organic si ay u sameeyaan xal muuqda oo muuqda. Dareeraha biyuhu wuxuu leeyahay dhaqdhaqaaqa dusha sare, daah-furnaan sare, iyo xasillooni xooggan, iyo kala diristeeda biyaha ma saameynayso pH. Waxay leedahay saameyn dhumuc iyo baraf ka hortag ah oo ku jirta shaambooyinka iyo shaambada qubeyska, waxayna leedahay haynta biyaha iyo sameynta aflaanta wanaagsan ee timaha iyo maqaarka. Iyada oo korodhka la taaban karo ee alaabta ceeriin ee aasaasiga ah, isticmaalka cellulose (antifreeze thickener) ee shaambooyinka iyo jelka qubayska waxay si weyn u dhimi kartaa kharashka waxayna gaari kartaa natiijooyinka la rabo.
Astaamaha Alaabta:
1. Solubility: ku milmay biyaha iyo qaar dareere organic ah. HEMC waxa lagu milmi karaa biyo qabow. Xoojinteeda ugu sareysa waxaa lagu go'aamiyaa kaliya viscosity. Solubility wuxuu la beddelaa viscosity. Maqnaanshaha hoose, waa ka sii weynaanta milanka.
2. Iska caabbinta milixda: Alaabooyinka HEMC waa ethers-cellulose-aan-ionic ah oo aan ahayn polyelectrolytes. Sidaa darteed, marka cusbada birta ah ama electrolytes organic ay joogaan, waxay ku xasilloon yihiin xalalka aqueous, laakiin ku darida xad-dhaafka ah ee electrolytes waxay keeni kartaa jel iyo roobab.
3. Dhaqdhaqaaqa dusha sare: Sida xalka aqueous uu leeyahay shaqada dhaqdhaqaaqa dusha, waxa loo isticmaali karaa sida wakiilka difaaca kolloid, emulsifier iyo kala firdhiso.
4. Gel kuleyl ah: Marka sheyga HEMC ee dareeraha aqueous lagu kululeeyo heerkul gaar ah, wuxuu noqdaa mid mugdi ah, jel ah, oo soo da'aya, laakiin marka si joogto ah loo qaboojiyo, waxay ku soo noqotaa xalalka asalka ah, iyo jelkan iyo roobka ayaa dhacaya Heerkulka Inta badan waxay ku xiran tahay saliidaha ay ku jiraan, qalabka joojinta, kolloidyada ilaalinta, emulsifiers iyo wixii la mid ah.
5. Dheef-shiid kiimikaad iyo ur yar iyo udgoon: Sababtoo ah HEMC ma noqon doonto metabolized oo ay leedahay ur iyo udgoon, si weyn ayaa loo isticmaalaa cuntada iyo daawada.
6. Caawinta caarada: HEMC waxay leedahay awood antifungal ah oo aad u wanaagsan iyo xasilloonida viscosity wanaagsan inta lagu jiro kaydinta muddada-dheer.
7. Xasiloonida PH: Viscosity of the HEMC sheyga xal aqueous si dhib leh u saameeyaa aashitada ama alkali, iyo qiimaha PH waa mid deggan inta u dhaxaysa 3.0-11.0.

(2) Hawdu ha ku socoto meesha kaydinta, ka fogow qorraxdu si toos ah, kana fogow ilaha dabka;
(3) Sababtoo ah hydroxyethyl methyl cellulose HEMC waa hygroscopic, waa inaan loo bandhigin hawada. Alaabta aan la isticmaalin waa in la xidhaa oo la kaydiyaa, lagana ilaaliyaa qoyaanka.
