Alaabta Ether Cellulose, Soo saaraha HPMC

Kiimikada Kima waa hogaamiyaha alaab-qeybiyaha ether-ka cellulose-ka caalamiga ah ee soo saarista iyo sahayda ethers-ka cellulose. Waxay bixiyaan alaabooyin badan oo ether cellulose ah oo loo isticmaalo warshado kala duwan sida dawooyinka, daryeelka shakhsi ahaaneed, dhismaha, iyo dahaarka. Ether-ka Kima Kiimikada cellulose waxaa lagu yaqaanaa tayada sare, joogtaynta, iyo waxqabadka.

Kiimikada Kima waxay caan ku tahay khibradeeda farsamada iyo taageerada macaamiisha, ka caawinta macaamiisha inay helaan alaabta ether-ka cellulose saxda ah codsiyadooda gaarka ah. Waxay leeyihiin joogitaan caalami ah oo leh xarumaha wax soo saarka iyo xafiisyada iibka ee gobollo kala duwan oo adduunka ah.

Eter cellulose waxaa loola jeedaa qoys ka kooban polymers-biyo-milmi leh oo laga soo qaatay cellulose, taas oo ah qaybta ugu muhiimsan ee dhismaha derbiyada unugyada dhirta. Polymers-yadan ayaa kiimiko ahaan wax laga beddelay si loogu soo bandhigo kooxaha shaqaynaya sida hydroxyethyl, hydroxypropyl, methyl, ama kooxaha karboxymethyl ee lafta dhabarka cellulose. Dib-u-habayntani waxay kor u qaadaysaa milanka biyaha iyo sifooyinka kale ee la rabo ee cellulose, taas oo ka dhigaysa mid faa'iido leh oo badan oo ah codsiyada warshadaha.

Ether-ka Cellulose waxaa si weyn loogu isticmaalaa dhumucyada, xasiliyeyaasha, xirayaasha, iyo kuwii hore ee filimada ee warshado kala duwan oo ay ka mid yihiin:

1. Dhismaha: Ether-ka Cellulose waxaa loo isticmaalaa agabka dhismaha sida hoobiyeyaal sibidh-ku-salaysan, xabag-tile, grouts, iyo alaabta gypsum-ku-salaysan si loo hagaajiyo karti-shaqsiyeedka, haynta biyaha, iyo guryaha isku-xidhka.
2. Daawooyinka: Qaababka dawooyinka, ethers-ka cellulose waxa loo isticmaalaa sida xidhayaasha soo saarista kiniinka, wax ka beddelayaasha viscosity ee qaabaynta dareeraha, iyo kuwii hore ee filimada ee codsiyada daahan.
3. Cunto: Ether-ka Cellulose waxa loo shaqeeyaa sidii dhumucyada, xasiliyayaal, iyo beddelayaasha baruurta ee alaabta cuntada sida suugada, dhaymada, waxyaabaha caanaha laga sameeyo, iyo walxaha rootiga.
4. Daryeelka Shakhsi ahaaneed: Waxaa loo isticmaalaa alaabta daryeelka shakhsi ahaaneed sida shaambada, labeennada, kiriimyada, iyo daawada cadayga sida dhumucyada, emulsifiers, iyo filim hore.
5. Rinjiyeynta iyo Dahaarka: Ethers Cellulose waxaa loo isticmaalaa sidii wax ka beddelka rheology iyo walxaha dhumucyada rinjiga biyaha ku salaysan, dahaarka, iyo xabagta si loo xakameeyo viscosity iyo hagaajinta sifooyinka codsiga.
6. Saliida iyo Gaaska: Warshadaha saliida iyo gaaska, ether-ka cellulose waxa loo isticmaalaa wax ka beddelka rheology ee qodista dareeraha si loo xakameeyo viscosity, sifaynta, iyo hantida luminta dareeraha.

Noocyada caadiga ah ee ethers cellulose waxaa ka mid ah methylcellulose (MC), hydroxypropyl methylcellulose (HPMC), hydroxyethyl cellulose (HEC), carboxymethyl cellulose (CMC), iyo ethylhydroxyethyl cellulose (EHEC). Nooc kastaa wuxuu bixiyaa sifooyin gaar ah oo ku habboon codsiyada kala duwan.
