Waa maxay hydroxyethyl methyl cellulose (HEMC)?

Waa maxay hydroxyethyl methyl cellulose (HEMC)?

 Hydroxyethyl methylcellulose(HEMCWaxa kale oo loo yaqaan methylhydroxyethyl cellulose (MHEC). Waa qayb cad oo cad, cawlan ama jaalle ah. Waa eter cellulose ah oo aan ionic ahayn oo la helay iyadoo lagu daro ethylene oxide methyl cellulose. Waxay ka samaysan tahay polymers dabiici ah oo la cusboonaysiin karo sida saxarka alwaax ama suufka, iyo HEMC waxaa loo isticmaali karaa sidii wax ku oolnimada sare ee wakiilka biyaha, koollada iyo wakiilka samaynta filimada, stabilizer, iwm Waxaa si ballaaran loo isticmaalaa codsiyada warshadaha kala duwan, sida saliidda. qodista, dhismaha iyo dhismaha, rinjiga iyo dahaarka, dawooyinka, iwm.HEMCwaxaa lagu beddeli karaa iyadoo loo eegayo shuruudaha macaamiisha, iyo ka dib markii wax laga beddelo, waxa ay weli leedahay iska caabin wanaagsan ee sagging iyo habaysan wanaagsan.

Astaamaha HEMC

HEMCwuxuu leeyahay hawlo kala duwan. Waxaa ka mid ah:

1. Muuqashada

 HEMCwuxuu noqon karaa caddaan, jaale khafiif ah, caddaan jaalle ah, ama caddaan cawl ah.

2. Solubility

HEMCwaa ku milmay biyaha (qabow ama kulul). InkastooHEMCwaa mid aan lagu milmi karin inta badan dareerayaasha organic, waxay ku milmi kartaa dareeraha organic binary iyo hababka biyaha dareeraha organic.

Xoog saaristeeda sare waxay ku xidhan tahay muuqalka, milmayntiisuna way ku kala duwan tahay mawqifka. The hoose viscosity, ka weyn ee milanka, iyo lid ku ah.

3. Xasiloonida pH

 HEMCwuu xasiloon yahay inta u dhaxaysa 3.0-11.0 iyo viscosity-kiisuna waa ku dhawaad ​​wax saamayn ah kuma yeelan, laakiin haddii xadkan la dhaafo waxay yaraynaysaa mawqifkiisa.

4. dheef-shiid kiimikaad

 HEMCwaa walax aan firfircooneyn oo si weyn loogu isticmaalo cuntada iyo daawada sababtoo ah awood la'aanta in ay maro dheef-shiid kiimikaad.

5. Dhaqdhaqaaqa dusha sare

Sababtoo ah shaqada firfircoon ee dusha sare ee xalalka aqueous, waxaa loo isticmaali karaa sida kala firdhiye, ilaaliye, iyo emulsifier.

6. caabbinta fungus

Kaydinta muddada-dheer,HEMCwaxay leedahay xasillooni viscosity wanaagsan, sidaas darteed waxay leedahay caabbinta caaryada wanaagsan.

Awoodeeda ka hortagga caaryada way ka sarraysaa ta hydroxyethyl cellulose.

7. Haysashada biyaha

 HEMCnoqda wakiilka biyaha-haynta wax ku ool ah sababtoo ah viscosity sare ee xalalka aqueous.

Awoodeeda xajinta biyaha ayaa ka weyn tan methyl cellulose.

8. Dambaska ku jira

Habka diyaarinta eeHEMCwaxay isticmaashaa dhaqida biyaha kulul, taasoo keentay in maadada dambaska ay aad u yar tahay.

9. Xabagta kulaylka leh

MarkaHEMCXalka waxaa lagu kululeeyaa heerkul gaar ah, daah-furnaantiisa ayaa hoos u dhacda, sameynta sediment iyo jel, laakiin haddii la qaboojiyo, waxay ku soo noqon doontaa xaaladdii asalka ahayd ee xalka.

Isticmaalka caadiga ah eeHEMChttps://www.longouchem.com/hpmc/

 Hydroxyethylmethylcellulosewaxaa loo isticmaali karaa sida:

Ø AdhesiveØ KolloidØ ThickenerØ Kahortagga Filimka

Codsiyada warshadaha eeHEMC

 HEMCwaxaa si weyn looga isticmaalaa warshadaha soo socda:

Isku-dar · dhoobada · Waxyaabaha la isku qurxiyo · Dhismaha · Cunnada iyo Cabbitaannada · Daawooyinka

Sidii hore loo sheegay.hydroxyethyl methylcellulose (HEMC) waa nooc ka mid ah methylcellulose. Waa eter cellulose aan ionic ahayn oo laga sameeyay alaabta suufka ah ee saafiga ah.HEMCHaysashada biyaha iyo dhumucdooda ayaa ka dhigaysa mid ku habboon rinjiyada cinjirka ah ee biyaha ku salaysan, khadadka iyo qodista batroolka, qalabka dhismaha, iwm. Sababo la xiriira isticmaalka baahsan ee codsiyada kala duwan, helitaankaHEMCalaab-qeybiyeyaasha caanka ah ee hydroxyethyl methyl cellulose waxay hubin karaan inaad hesho alaab ku habboon isticmaalka shakhsi ahaaneed ama warshadaha.https://www.longouchem.com/hpmc/
