Ethers Cellulose ee codsiyada xabagta ku salaysan ee cinjirka

Hordhac:

Xabag-ku-salaysan cinjirka ayaa si weyn looga isticmaalaa warshado kala duwan taas oo ay ugu wacan tahay kala duwanaanshahooda, xoogga isku-xidhka, iyo saaxiibtinimada deegaanka. Xabagyadani waxay ka kooban yihiin kala firidhsan walxaha polymer-ka ee biyaha, iyadoo latex uu yahay qaybta koowaad. Si kastaba ha ahaatee, si kor loogu qaado waxqabadkooda oo loogu habeeyo codsiyo gaar ah, waxyaabo lagu daro oo kala duwan ayaa lagu daraa qaababka xabagta ku salaysan ee cinjirka. Waxyaabaha lagu daro, ether-ka cellulose-ka ayaa door muhiim ah ka ciyaara, soona bixiya sifooyin la jecel yahay sida xakamaynta viscosity, haynta biyaha, iyo hagaajinta xabagta.

Guryaha Ethers Cellulose:

Ethers-ka Cellulose waa unugyo ka soo jeeda cellulose, polymer-ka dabiiciga ah ee laga helo gidaarada unugyada dhirta. Waxaa lagu helaa iyadoo kiimiko ahaan wax looga beddelayo cellulose iyada oo loo marayo falcelinta etherification. Noocyada ugu caansan ee ethers-ka cellulose-ka ee loo isticmaalo xabagta ku salaysan cinjirka waxaa ka mid ah methyl cellulose (MC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), iyo carboxymethyl cellulose (CMC). Nooc kastaa wuxuu soo bandhigaa sifooyin gaar ah oo gacan ka geysta waxqabadka xabagta ku salaysan cinjirka.

Xakamaynta viscosity:

Mid ka mid ah hawlaha aasaasiga ah ee ethers cellulose ee xabagta ku salaysan cinjirka waa xakamaynta viscosity. Ku darida ethers cellulose waxay caawisaa hagaajinta viscosity ee qaabaynta xabagta, taas oo sahlaysa in la xakameeyo oo la codsado. Marka la beddelo viscosity-ka, ethers-ka cellulose-ku waxa ay awood u siinaysaa xakamaynta saxda ah ee socodka iyo fidinta sifooyinka koollada, hubinta daboolka isku midka ah iyo xoogga isku xidhka.

Haynta Biyaha:

Ether-yada Cellulose waa polymers hydrophilic oo awood u leh inay nuugaan oo ay hayaan molecules biyaha. Codsiyada xabag-ku-salaysan ee latex-ku-salaysan, hantidan ayaa si gaar ah faa'iido u leh maadaama ay kor u qaadayso wakhtiga furan ee xabagta-muddada ay koollada sii ahaanayso mid shaqayn karta codsiga ka dib. Dib u dhigista habka qalajinta, ethers cellulose waxay kordhiyaan daaqada si ay u dhigaan meel sax ah iyo hagaajinta substrates xiran, taas oo fududeynaysa curaarta adag oo la isku halleyn karo.

Horumarinta Adhesion:

Ethers Cellulose sidoo kale waxay gacan ka geystaan ​​waxqabadka xabagta iyagoo kor u qaadaya isdhexgalka wajiyada u dhexeeya koollada iyo sagxadaha substrate-ka. Iyada oo la adeegsanayo isku xidhka hydrogen iyo habab kale, ethers cellulose waxay kor u qaadaan qoynta iyo ku dhejinta substrates kala duwan, oo ay ku jiraan alwaax, waraaqo, dhar, iyo dhoobo. Tani waxay keenaysaa horumarinta xoogga curaarta, adkaysiga, iyo iska caabinta arrimaha deegaanka sida qoyaanka iyo isbedbeddelka heerkulka.

Waafaqsanaanta Polymers-ka Latex:

Faa'iidada kale ee muhiimka ah ee ethers-ka cellulose waa ku habboonaanta polymers-ka cinjirka ah. Dabeecadda la midka ah ee hydrophilic awgeed, ethers cellulose waxay u kala firdhiyaan si isku mid ah kala firdhisanaanta cinjirka iyada oo aan wax saameyn ah ku yeelan xasiloonidooda ama sifooyinka rheological. Iswaafajintani waxa ay hubisaa qaybinta isku mid ah ee waxyaabaha lagu daro inta lagu jiro matrixka xabagta, si loo wanaajiyo waxqabadka loona yareeyo iswaafaq la'aanta qaabaynta.

Joogteynta Deegaanka:

Ether-ka Cellulose waxaa laga soo qaatay kheyraadka dib loo cusboonaysiin karo, taasoo ka dhigaysa wax lagu daro deegaan ahaan waara oo loogu talagalay xabagta cinjirka ku saleysan. Si ka duwan polymers synthetic, kuwaas oo ka soo jeeda petrochemicals, ethers cellulose waa biodegradable oo keena saamaynta deegaanka ugu yar. Maaddaama baahida loo qabo xalalka xabagta-saaxiibtinimo ee deegaanka ay koraan, ether-yada cellulose waxay bixiyaan beddelka qasabka ah ee soosaarayaasha doonaya inay yareeyaan raadkooda kaarboonka oo ay u hoggaansamaan xeerarka waaridda.

Gabagabo:

Ethers cellulose waxay door muhiim ah ka ciyaaraan kor u qaadida waxqabadka xabagta cinjirka ku salaysan ee codsiyada kala duwan. Laga soo bilaabo xakamaynta viscosity iyo haynta biyaha ilaa hagaajinta adhesion iyo joogteynta deegaanka, ethers cellulose waxay bixiyaan faa'iidooyin fara badan oo gacan ka geysta sameynta iyo shaqeynta xabagta. Maadaama warshaduhu ay sii wadaan inay abuuraan oo ay raadiyaan beddelaadyo cagaarka ah, ethers cellulose waxay diyaar u yihiin inay sii ahaanayaan wax lagu daro horumarinta jiilka soo socda ee xalalka dhejiska ah.
