Nguwuphi umahluko phakathi kwe-sellulose ne-HPMC?

Iseli Ngelixa babelana ngokufana, bakwahlukene ngokwahlukileyo ngokwendlela abo yokwakha iikhemikhali, iipropathi, zokusebenzisa kunye neenkqubo zeMveliso.

1.Kwazisa uMgangatho:

Iseli:
I-sellyulose yinto ye-PolysacCreackacking equka amakhonkco amade e-Glucose Molekrus edityaniswe kunye β-1,4-Glycosidic Bonds. Yeyona nto iphambili kwiindonga zeseli zezityalo, ukubonelela ngenkxaso yesakhiwo kunye nobungqola bokutyala izicubu. I-selsulose Molecules ye-microfiibrils ye-hydrogen, igalelo kumandla kunye nokungena kwento yokutyibilika kweselfowuni emanzini kunye nezona zinzima zezinto eziphilayo.

I-HPMC:
I-HydroxyPOpyl Methylcelcelsulose (HPMC) yi-polymer ye-semi-sydhemetic ethathwe kwi-selsulose ngokuguqula iikhemikhali. Iveliswa ngokuphatha i-seluplose kunye ne-propylene oxide kunye ne-methyl chloride ukwazisa i-hydroxyl kunye namaqela e-AFGESS kwi-SellXose. Inqanaba lokufakwa endaweni yala maqela linokwahluka, lichaphazela iipropathi ze-HPMC ezinje ngomoya wokuzola, i-viscosity, kunye nokuziphatha kwenqanawa.

2.Properties:

Iseli:
I-Insoolukiety: I-Illoulose emsulwa i-insulbled emanzini nase-organic izinyibilikisi ngenxa ye-hydrogen ye-hydrogen ye-hydrogen kunye ne-crystalline.
I-biodegradiance: I-SellUlose i-Biodegrades, esenza ukuba ibe nobuhlobo kwaye ilungele izicelo ezahlukeneyo ze-eco.
Amandla oomatshini: Iintsinga zeselselose zinamandla amakhulu e-thensile, zinegalelo ekusebenziseni kwazo ephepheni, izinto ezibhaliweyo, kunye nezixhobo ezihlanganisiweyo.
Ukunqongophala kwendawo yokuhlala: I-seluplose i-camictures kwaye ayisabi lula kwezinye iziqu eziphantsi kweemeko eziqhelekileyo.

I-HPMC:
Ukuluka: I-HPMC ibonisa ukugcwala emanzini, ukwenza izisombululo ezibonakalayo kunye ne-viscous. Ukuluka kwabantu, kuxhomekeke kwizinto ezinje ngenqanaba lokufakwa endaweni, ubunzima bemolekyuli, kunye nobushushu.
Ukuqulunqwa kwefilimu: I-HPMC inokwenza iifilimu eziguqukayo nezingabonakaliyo zomisa, zenze ukuba kube luncedo kwimveliso yamachiza, ukupakisha ukutya, kunye nezinye iinkqubo.
I-Viscofity: Izisombululo ze-HPMC zinophawu olunokutshintsha olusekwe kwizinto ezinje ngoxinzelelo, ubushushu, kunye nesidanga sokufaka endaweni. Le ndawo ibalulekile ekulawuleni i-raToology yokuziphatha.
I-bioadesion: i-HPMC inepropathi yebhadisa, ivumela ukuba ilandele indawo yebhayoloji efana ne-mucosal membrane. Eli nqaku lixhaphazwa kwimigaqo yamayeza yokuhanjiswa kweziyobisi.

3. Iindlela zokusebenzisa:

Iseli:
Iphepha kunye nekhadibhodi: Iintsinga zeselselose zizixhobo eziphambili zephepha kunye nemveliso yekhadibhodi ngenxa yendalo yabo kunye namandla abo.
I-Cotton, i-cotton, i-fiber yendalo equlunqwe ikakhulu ye-selsulose, isetyenziswa ngokubanzi kumzi-mveliso weempahla ngeempahla, i-upholstery, kunye nezinye iimveliso ezisekwe kwilaphu.
Izinto zokwakha: Izinto ezisekwe seselfowuni ezinjengeenkuni, iPlywood, kunye ne-paricboard ziqhelekile ekwakhiweni kweenjongo zesakhiwo kunye nokuhombisa.
Izongezo zokutya: I-Selexlose Derivastitives efana ne-microcrystalline ye-microcrystalline kunye ne-carboxymethyl isetyenziswa njenge-thisfulose isetyenziswa njengamanzi amakhulu, ukuzinza, kunye neearhente zokugungxula kwiimveliso zokutya.

I-HPMC:
Ifomu yamayeza: I-HPMC isetyenziswa kakhulu kwiindawo zamayeza njenge-binder, ifilimu yangaphambili, i-arhente yokukhupha, kunye ne-viscofiers, i-vipbus, ifomu ye-Ophthalmimic.
Izixhobo zokwakha: I-HPMC yongezwa kwiimveliso ezisekwe kwimo yesamente ezinjengokufa, imifuno ye-tile, kunye nenqanaba lokuzibandakanya ukuphucula ukusebenza, ukugcinwa kwamanzi, kunye nepropathi yokubulala.
Ishishini lokutya: I-HPMC iqeshwa i-gickener, i-enulsifier, i-statilizer, kunye ne-fible ye-fible eyongezelelweyo kwiimveliso zokutya, kubandakanya iisosi, iidesser, kunye ne-dessert.
Iimveliso zononophelo lobuqu: i-HPMC ifumaneka kwi-cosmetics, iindlu zangasese, kunye nezinto zokhathalelo zobuqu ezifana ne-ores, i-crims, i-shamps, kunye nefilimu, kunye nefilimu yangaphambili.

Inkqubo yokuSebenza yokuSebenza:

Iseli:
I-seluplose ngokuyintloko ifumaneka kwimithombo yezityalo kwiinkqubo ezinje ngokutsalwa koomatshini (umz. I-selsulose ekhutshiweyo iphantsi kokucocwa kunye nokulungisa ukufumana iifom ezahlukeneyo ezifanelekileyo kwizicelo ezahlukeneyo.

I-HPMC:
Ukuveliswa kwe-HPMC kubandakanya amanyathelo aliqela, ukuqala ngokukhupha i-selsulose ukusuka kwimithombo yezityalo efana ne-pulp okanye i-cotton ezinemithi. I-selsulose inyangwa ngeAlkali ukuba isuse ukungcola ngaphambi kokuthatha inxaxheba kwi-oxide ye-oxide kunye ne-propyl oxide kunye ne-methyl chloride ukwazisa amaqela e-hydroxy kunye ne-mayiptions, ngokwahlukeneyo. I-HPMC ekhuthazayo ihlanjululwe, yomile, kwaye ihlawulwe kubungakanani obufunekayo bokusetyenziswa kwezorhwebo.

I-SellUlose kunye ne-HPMC zimbini iziko elibalulekileyo kunye nezicelo ezahlukileyo kumashishini ahlukeneyo. Ngelixa i-seluplose yi-Polysaccharide yeNdalo efumaneka kwiindonga zeseli ezityalo, i-HPMC yindawo efudumeleyo yesellulose yokuphucula ukubenzela amandla kunye nokusebenza. Ukwahluka kwabo kubume beekhemikhali, iipropathi, izicelo kunye neenkqubo zokwenza imveliso zibenza balungele ukusetyenziswa, ukusukela kwimveliso yemveli yemveli kunye neMpahla kwiNkqubo yeZithuba eziPhezulu kunye nezixhobo zokwakha. Ukuqonda ezi mbandela kubalulekile ukuba kukhangele iipropathi ezizodwa zeSelelUlose kunye ne-HPMC ekuphuhliseni iimveliso ezintsha kunye nezisombululo ezizinzileyo.
