Heerka dhismaha HEMC

Heerka dhismaha HEMCHydroxyethylMethylCellulosewaxaa loo yaqaan Methyl Hydroxyethyl Cellulose (MHEC),waa budo cad ama aan cadaan ahayn, aan ur lahayn oo aan dhadhan lahayn, milmi karaBiyo kulul iyo biyo qabow labadaba. Heerka dhismaha HEMC waa la bedeli karaaWaxaa loo isticmaalaa sibidh, gypsum, wakiilka jelling lime, wakiilka haynta biyaha, waa isku-darka aad u fiican ee qalabka dhismaha budada.

Qaab-dhismeedka Molekulerka:

Astaamaha Badeecada:

1. Muuqaal: HEMC waa budo cad ama ku dhawaad ​​​​cad; ur la'aan iyo dhadhan la'aan.

2. Milmida: Nooca H ee HEMC waxaa lagu milmi karaa biyo ka hooseeya 60℃, nooca L-na waxaa lagu milmi karaa oo keliya biyo qabow. HEMC waa la mid HPMC waana mid aan milmi karin inta badan dareerayaasha dabiiciga ah. Ka dib daaweynta dusha sare, HEMC waxay ku faaftaa biyo qabow iyada oo aan la isku milmin waxayna si tartiib ah u milmaysaa, laakiin si dhakhso ah ayaa loo milmi karaa iyadoo la hagaajinayo qiimaha PH ilaa 8-10.

3. Xasiloonida qiimaha PH: Dheef-dhalashada wax yar ayay iska beddeshaa inta u dhaxaysa 2-12, dheef-dhalashadana way hoos u dhacdaa marka laga reebo xadkan.

4. Fiicnaan: heerka gudbinta ee 80 mesh waa 100%; heerka gudbinta ee 100 mesh waa ≥99.5%.

5. Cufisjiidadka gaarka ah ee beenta ah: 0.27-0.60g/cm3.

6. Heerkulka kala-baxa wuxuu ka sarreeyaa 200℃, wuxuuna bilaabaa inuu ku gubo 360℃.

7. HEMC waxay leedahay dhumuc weyn, xasillooni la'aan, kala firdhis, isku xirnaan, qaabayn, haynta biyaha iyo astaamo kale.

8. Maadaama badeecadu ay ka kooban tahay kooxda hydroxyethyl, heerkulka jelka ee badeecaddu wuxuu gaaraa 60-90℃. Intaa waxaa dheer, kooxda hydroxyethyl waxay leedahay hydrophilicity sare, taas oo sidoo kale ka dhigaysa heerka isku xidhka badeecaddu mid wanaagsan. Gaar ahaan dhismaha heerkulka kulul iyo kan sare ee xagaaga, HEMC waxay leedahay haynta biyaha oo ka sarreysa methyl cellulose oo isku mid ah, heerka haynta biyuhuna kama yaraan 85%.

Darajada Badeecadaha

Muhiimadda

Sida wakiil firfircoon oo dusha sare ah, hydroxyethyl methyl cellulose HEMC waxay leedahay sifooyinka soo socda marka lagu daro dhumucda, joojinta, isku xidhka, emulsifying, sameynta filimada, kala firdhinta, ilaalinta biyaha iyo bixinta kolloids ilaalin ah:

(1) Hydroxyethyl methyl cellulose HEMC waxay ku milmi kartaa biyo kulul ama qabow, taasoo ka dhigaysa inay leedahay astaamo badan oo milmi kara iyo dheellitirnaan, taas oo ah, jelitaanka aan kuleylka ahayn;

(2) Hydroxyethyl methyl cellulose HEMC waxay la noolaan kartaa noocyo badan oo polymers kale oo biyaha ku milma, surfactants, iyo milix, waana dhumuc weyn oo loogu talagalay xalalka elektrolytka ee xoogga badan;

(3) HEMC waxay leedahay haysashada biyaha oo ka xoog badan methyl cellulose, xasilloonideeda, kala firdhisnaanteeda, iyo iska caabbinta caariyaysiguna way ka xoog badan yihiin tan hydroxyethyl cellulose.

Habka diyaarinta xalka

(1) Ku dar xaddi cayiman oo biyo nadiif ah weelka;

(2) Ku dar hydroxyethyl methyl cellulose HEMC adigoo si degdeg ah u walaaqaya, oo walaaq ilaa dhammaan hydroxyethyl methyl cellulose ay si siman u milmaan;

(3) Marka la eego xogta tijaabada farsamada, waxaa si xooggan loogu talinayaa in lagu daro ka dib marka lagu daro emulsion-ka polymer-ka (tusaale ahaan, hydroxyethyl methyl cellulose)Qalabka Caafimaadka Dadweynaha (HEMC)waxaa hore loogu qasay ethylene glycol ama propylene glycol).
