Heerka dhismaha ee HEMC

Heerka dhismaha HEMC Hydroxyethyl Methyl Cellulose waxaa loo yaqaan Methyl Hydroxyethyl Cellulose (MHEC), waa budo cad ama ka baxsan, ur la'aan iyo dhadhan la'aan, ku milma biyaha kulul iyo biyaha qabow labadaba.Heerka dhismaha ee HEMC waxaa loo isticmaali karaa sibidh ahaan, gypsum, wakiilka lime gelling, wakiilka biyaha, waa isku darka aad u fiican ee qalabka dhismaha budada ah.

Qaab-dhismeedka Molecular:

Astaamaha Alaabta:

1. Muuqashada: HEMC waa caddaan ama ku dhowaad budo cad;aan ur lahayn oo aan dhadhamin.

2. Solubility: Nooca H ee HEMC waxa lagu milmi karaa biyo ka hooseeya 60 ℃, nooca L-na waxa lagu milmi karaa oo keliya biyo qabow.HEMC waxay la mid tahay HPMC waana mid aan lagu milmi karin inta badan dareerayaasha organic.Daaweynta dusha sare ka dib, HEMC waxay ku firdhisaa biyo qabow iyada oo aan la kicin oo si tartiib ah u milaan, laakiin si dhakhso ah ayaa loo milmi karaa iyada oo la hagaajinayo qiimaha PH ilaa 8-10.

3. Degganaanshaha qiimaha PH: Viscosity-ku wax yar ayuu isu beddelaa inta u dhaxaysa 2-12, mawjadaha ayaa hoos u dhacay wixii ka baxsan xadkan.

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

5. Cuf-jiid gaar ah oo been abuur ah: 0.27-0.60g/cm3.

6. Heerkulka burburku wuxuu ka sarreeyaa 200 ℃, wuxuuna bilaabaa inuu ku gubto 360 ℃.

7. HEMC waxa ay leedahay dhumuc weyn, xasilooni laalid, kala firdhisanaan, isku xidhnaan, caaryo, xajin biyaha iyo sifooyin kale.

8. Sababtoo ah alaabtu waxay ka kooban tahay kooxda hydroxyethyl, heerkulka jel ee alaabtu wuxuu gaaraa 60-90 ℃.Intaa waxaa dheer, kooxda hydroxyethyl waxay leedahay hydrophilicity sare, taas oo sidoo kale ka dhigaysa heerka badeecada midaysan.Gaar ahaan dhismaha kulaylka iyo heerkulka sare ee xagaaga, HEMC waxay leedahay haynta biyaha ka sarreeya methyl cellulose oo isku mid ah, heerka haynta biyuhuna kama yarayn 85%.

Darajada Alaabta   

Muhiimada

Sida wakiilka firfircoon ee dusha sare, hydroxyethyl methyl cellulose HEMC waxay leedahay sifooyinka soo socda marka lagu daro dhumuc, laalista, isku xidhka, emulsifying, filim samaynta, kala firdhinta, ilaalinta biyaha iyo bixinta kolloidyada ilaalinta:

(1).

(2) Hydroxyethyl methyl cellulose HEMC waxay la noolaan kartaa tiro balaadhan oo ah polymers-ka kale ee biyaha-milmi kara, surfactants, iyo cusbada, waana dhumuc aad u fiican oo loogu talagalay xalalka korantada ee xoogga leh;

(3) HEMC waxay leedahay haynta biyaha ka xoog badan methyl cellulose, iyo xasiloonideeda viscosity, kala dirid, iyo caabbinta caariyaysigu way ka xoog badan tahay kan cellulose hydroxyethyl.

Habka diyaarinta xalka

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

(2) Ku dar hydroxyethyl methyl cellulose HEMC hoos walaaqaya xawaare hooseeya, oo walaaq ilaa dhammaan hydroxyethyl methyl cellulose si siman loo kala diro;

(3) Marka la eego xogtayada tijaabada farsamada, waxaa si xoog leh lagula talinayaa in lagu daro ka dib marka lagu daro emulsion polymer (ie, hydroxyethyl methyl cellulose HEMC waxaa horay loogu daray ethylene glycol ama propylene glycol).

Usda'da

Qalabka dhismaha ee warshadaha, heerka dhismaha ee HEMC wuxuu ku habboon yahay koolada foornada, balastarrada sibidhka, hoobiye qallalan oo qallalan, is-barbardhigga, balaastarka gypsum, rinjiga latex, xirmooyinka walxaha dhismaha, beeraha kale ee dhismaha, qodista saliidda, alaabada daryeelka shakhsi ahaaneed, wakiilada nadiifinta, iwm. , guud ahaan loo isticmaalo sida dhumucyada, wakiilada ilaalinta, dhejisyada, xasiliyeyaasha, iyo wakiilada joojinta waxaa sidoo kale loo isticmaali karaa sida jeliyeyaasha hydrophilic, qalabka matrixka, diyaarinta nooca matrix-nooca sii-daynta sii-deynta, iyo sidoo kale waxaa loo isticmaali karaa xasiliyeyaasha cuntooyinka, iwm. .

Pku dacwayn iyo kaydinta

(1) Lagu soo buuxiyey bac-caag ah oo isku dhafan warqad-caag ah ama boorso warqad ah, 25KG/bac;

(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 in aan loo bandhigin hawada.Alaabta aan la isticmaalin waa in la xidhaa oo la kaydiyaa, lagana ilaaliyaa qoyaanka.
