4 Farsamooyinka Wax Soosaarka Aasaasiga ah iyo Qaababka HPMC, Ha maqnaan!

Hydroxypropyl methylcellulose (HPMC) waa polymer isku dhafan oo si weyn loogu isticmaalo warshado kala duwan, oo ay ku jiraan dhismaha, daawooyinka, iyo warshadaha cuntada.HPMC waxa la soo saaray iyadoo la isticmaalayo tignoolajiyada wax soo saarka kala duwan iyo qaabaynta, iyadoo ku xidhan codsiga loogu talagalay.Maqaalkan, waxaan ku baari doonaa afar tignoolajiyada wax soo saarka aasaasiga ah iyo qaaciidooyinka HPMC oo ay tahay inaadan seegin.

1. Tignoolajiyada Etherification Tignoolajiyada etherification waa tignoolajiyada wax soo saarka ee inta badan loo isticmaalo HPMC.Habkan, cellulose waxaa lagu daaweeyaa alkali, sida sodium hydroxide, si loo sameeyo alkali cellulose.cellulose-ka alkali waxa lagu falceliyaa propylene oxide iyo methyl chloride si loo sameeyo HPMC.Heerka beddelka (DS) ee HPMC waxaa lagu xakameyn karaa iyadoo la hagaajinayo saamiga propylene oxide iyo methyl chloride inta lagu jiro falcelinta.

Habka HPMC ee la soo saaray iyadoo la isticmaalayo tignoolajiyada etherification waa:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → HPMC

2. Tignoolajiyada qalajinta buufinta tignoolajiyada qalajinta buufintu waa tignoolajiyada wax soo saarka ee aad u horumarsan ee HPMC.Nidaamkan, cellulose wuxuu ku milmaa xalalka alkali ka dibna waxaa lagu falceliyaa propylene oxide iyo methyl chloride.Xalka HPMC ee ka soo baxay ayaa markaa lagu buufiyaa la qalajiyey si loo soo saaro budada HPMC.

Habka HPMC ee la soo saaray iyadoo la isticmaalayo tignoolajiyada qalajinta buufinta waa:

Cellulose + Alkali → Alkali Cellulose Alkali Cellulose + Propylene Oxide + Methyl Chloride → HPMC Xalka HPMC Xalka + buufinta qalajinta

3. Farsamooyinka Polymerization-ka Joojinta Tignoolajiyada polymerization hakinta waa tignoolajiyada wax soo saarka kale ee HPMC.Habkan, cellulose ayaa lagu hakiyaa dareeraha ka dibna waxaa lagu falceliyaa propylene oxide iyo methyl chloride iyada oo ay joogaan bilawga polymerization si loo sameeyo HPMC.

Qaacidada HPMC ee la soo saaray iyadoo la isticmaalayo tignoolajiyada polymerization hakinta waa:

Cellulose + Solvent + Polymerization Initiator → Joojinta Cellulose Joojinta Cellulose + Propylene Oxide + Methyl Chloride → HPMC

4. Tiknooloojiyada Polymerization Solution Xalka tignoolajiyada polymerization-ka ayaa ah tignoolajiyada wax soo saarka ee cusub ee HPMC.Habkan, cellulose waxa lagu milmaa dareere ka dibna waxa lagu falceliyaa propylene oxide iyo methyl chloride iyada oo ay joogaan hindise polymerization si loo sameeyo HPMC.

Habka HPMC ee la soo saaray iyadoo la isticmaalayo tignoolajiyada polymerization xal waa:

Cellulose + Solvent + Polymerization Initiator → Cellulose Solution Cellulose Solution + Propylene Oxide + Methyl Chloride → HPMC

Gebagebadii, HPMC waa polymer-ka-badan oo la soo saaray iyadoo la adeegsanayo tignoolajiyada wax soo saarka ee kala duwan iyo qaabaynta, iyadoo ku xidhan codsiga loogu talagalay.Afarta teknoolajiyada wax soo saarka aasaasiga ah iyo qaaciidooyinka HPMC waxaa ka mid ah tignoolajiyada etherification, tignoolajiyada qalajinta buufinta, tignoolajiyada polymerization-ka joojinta, iyo tignoolajiyada polymerization xalka.Fahamka tignoolajiyada wax soo saarka iyo qaacidada HPMC waxay ka caawin kartaa soosaarayaasha inay doortaan badeecada HPMC ee ku haboon codsiyadooda gaarka ah.
