Cellulose Ether - dulmar

Eter celluloseWaxa loola jeedaa qoys ka mid ah polymers-ka biyaha-milmi kara oo ka yimid cellulose, polymer-ka dabiiciga ah ee laga helo gidaarada unugyada dhirta. Eter-yadan waxaa lagu abuuray iyada oo loo marayo hagaajinta kiimikada ee cellulose, taasoo keentay koox isku dhafan oo isku dhafan oo leh codsiyada kala duwan ee warshadaha sida dhismaha, daawooyinka, cuntada, dunta, iyo qurxinta. Halkan waxaa ah dulmar guud oo ku saabsan ether cellulose, hantideeda, iyo codsiyada caadiga ah:

Astaamaha Eter-ka Cellulose:

1. Biyo milmayn:
   • Ether-ka Cellulose waa biyo-milmi kara, taas oo u oggolaanaysa inay sameeyaan xalal cad oo muuqda marka lagu qaso biyaha.
2. Wakiilka Dhumucda:
   • Mid ka mid ah sifooyinka aasaasiga ah ee ethers cellulose waa awoodda ay u leeyihiin inay u dhaqmaan sidii dhumucyo waxtar leh ee xalalka aqueous. Waxay si weyn u kordhin karaan viscosity ee hababka dareeraha.
3. Guryaha Samaynta Filimada:
   • Qaar ka mid ah ether-ka cellulose-ka ayaa soo bandhiga sifooyin-samaynta filimada. Marka lagu dabaqo dusha sare, waxay abuuri karaan filimo khafiif ah oo khafiif ah.
4. Rheology la hagaajiyay:
   • Ethers Cellulose waxay gacan ka geystaan ​​sifooyinka rheological ee qaab-dhismeedka, hagaajinta socodka, xasilloonida, iyo kartida shaqada.
5. Haynta Biyaha:
   • Waxay leeyihiin awood aad u wanaagsan oo lagu hayo biyaha, iyaga oo ka dhigaya kuwo qiimo leh qalabka dhismaha si loo xakameeyo wakhtiyada qallajinta.
6. Isku-xidhka iyo Isku-xidhka:
   • Ether-yada Cellulose waxay kor u qaadaan ku-xidhka sagxadaha kala duwan iyo isku-duubnida qaab-dhismeedka, taas oo gacan ka geysata waxqabadka guud ee alaabta.

Noocyada caadiga ah ee Ethers Cellulose:

1. Methylcellulose (MC):
   • Waxa lagu soo bandhigay kooxaha methyl cellulose. Loo isticmaalo sidii dhumuc ahaan codsiyo kala duwan, oo ay ku jiraan qalabka dhismaha, daawooyinka, iyo cuntada.
2. Hydroxypropyl Methylcellulose (HPMC):
   • Lagu beddelay labada kooxood ee hydroxypropyl iyo methyl. Si weyn loogu isticmaalo warshadaha dhismaha ee hoobiyeyaal, xabagta tile, iyo rinjiga. Sidoo kale loo isticmaalo daawooyinka iyo cuntada.
3. Hydroxyethyl Methylcellulose (HEMC):
   • Waxa ku jira kooxaha hydroxyethyl iyo methyl. Loo isticmaalo agabka dhismaha, rinjiyada, iyo dahaarka si ay u dhumucdiso una dejiso.
4. Carboxymethylcellulose (CMC):
   • Kooxaha Carboxymethyl waxaa lagu soo bandhigaa cellulose. Inta badan loo isticmaalo warshadaha cuntada sidii dhumuc iyo xasiliye. Sidoo kale loo isticmaalo daawooyinka iyo sida wakiilka daahan warqad.
5. Ethylcellulose:
   • Lagu beddelay kooxaha ethyl. Loo isticmaalo warshadaha dawooyinka qaabaynta dawooyinka la xakameeyey, dahaarka, iyo xabagta.
6. Microcrystalline Cellulose (MCC):
   • Lagu helo in lagu daaweeyo cellulose aashito iyo hydrolyzing. Loo isticmaalo warshadaha dawooyinka sida xidhe iyo buuxinta qaabaynta kiniinka.

Codsiyada Ethers Cellulose:

1. Warshadaha Dhismaha:
   • Waxaa loo adeegsadaa hoobiyeyaal, xabag-ku-dhegyo, grouts, iyo dahaarro si loo hagaajiyo karti-shaqsiyeedka,-dhejinta, iyo haysashada biyaha.
2. Daawooyinka:
   • Waxaa laga helay qaab-dhismeedka kiniinka sida xidhayaasha, kala-baxa, iyo wakiilada filim samaynta.
3. Warshadaha cuntada:
   • Loo isticmaalo sidii dhumucyada, xasiliyayaasha, iyo emulsifiers ee alaabta cuntada.
4. Rinjiyeynta iyo Dahaarka:
   • Ka qaybqaado rheology-ga iyo xasilloonida rinjiyada iyo dahaarka biyaha ku salaysan.
5. Alaabooyinka Daryeelka Qofka:
   • Loo isticmaalo waxyaalaha la isku qurxiyo, shaambooyinka, iyo labeennada si ay u dhumuyaan una dejiyaan.
6. Dharka
   • Looga shaqeeyo sidii wakiilada cabbirka ee warshadaha dharka si loo hagaajiyo sifada wax ka qabashada dunnooyinka.
7. Warshadaha Saliida iyo Gaaska:
   • Loo isticmaalo qodista dareeraha si loo xakameeyo rheology.

Tixgelin:

• Heerka Beddelka (DS):
  • DS-ku waxa uu tilmaamayaa celceliska tirada kooxaha beddelka ah ee unugga gulukoosta ee silsiladda cellulose, taas oo saamaynaysa sifooyinka ethers cellulose.
• Miisaanka Molecular:
  • Miisaanka molecular ee ethers-ka cellulose wuxuu saameeyaa viscosity-kooda iyo guud ahaan waxqabadka qaab-dhismeedka.
• Joogteynta:
  • Tixgelinta isha cellulose, habaynta deegaanka-saaxiibtinimo, iyo biodegradability ayaa sii kordheysa muhiim u ah soosaarka etherka cellulose.

Kala-duwanaanta ethers-ka Cellulose iyo sifooyinka gaarka ah ayaa ka dhigaya qaybo lagama maarmaan u ah badeecooyin kala duwan, ka qaybqaata horumarinta waxqabadka, xasiloonida, iyo shaqada ee warshadaha kala duwan.
