Yintoni i-HPMC?

I-HydroxyPOpyl Methylcelcelsele (i-HPMC) yi-polymer eguquguqukayo efumana izicelo ezibanzi kumashishini ahlukeneyo, kubandakanya amayeza, ukutya, ukwakhiwa kunye ne-cosmetics. Iipropathi zayo ezizodwa zikwenza ukuba zingabalulekanga kwiziko elifuna ukulungiswa kwe-viscofity, ukuqulunqwa kwefilimu, ukubopha, kunye nophuhliso lokuzinza. Ukuqonda ubume, inkqubo yokwenziwa, iipropathi, kunye nokusetyenziswa kwe-HPMC kubalulekile ekusebenziseni kakuhle.

1.Ukuchazwa kwe-HPMC

I-HPMC yi-polymer ye-semi-synthete ethathwe kwi-seluplose, i-Polysaccharackacchacchaccharackacchacchacchaacchaacchaacchacchaacchaacchaacchaackac efumaneka kwiindonga zeseli. Inkqubo yokwenziwa ibandakanya ukunyanga i-sellulose nealkali ukuvelisa i-alkali selsulose, ilandelwe yi-ether kunye ne-propylene oxide kunye ne-methyl chloride. Ezi ziphumo zolungiso lweekhemikhali ekusungulweni kwe-hydroxylpropy ye-hydroxypropy kunye ne-AFPUSGSY STATICUSS kwi-Selelose Parlebnene, i-HPMC.

Inqanaba lokufakwa endaweni (DS) le-hydroxypropy kunye namaqela e-Managesy ibeka iipropathi ze-HPMC, kubandakanya ukubenzela amandla, ukungcwaba, kunye neempawu zokwenza ifilimu. Ngokwesiqhelo, amabakala e-HPMC ngexabiso le-DS ephezulu ye-DS eveling yondla kumanzi kunye nokuphuculwa komthamo.

2.IProperties ye-HPMC

I-Solity yaManzi: I-HPMC inyibilikisa emanzini abandayo, yenza izisombululo ezicacileyo nezichazayo. Ukuluka kunokulungelelaniswa ngokuhlengahlengisa inqanaba lokufaka endaweni, ubunzima bemolekyuli, kunye nobushushu.

Ukuqulunqwa kwefilimu: I-HPMC inokwenza iifilimu eziguqukayo nezingabonakaliyo zomisa. Ezi filimu zinezithintelo ezigqwesileyo, zibenza bazilungele izicelo eziqengqelekayo kwiindawo zamachiza kunye nemizi-mveliso yokutya.

Ukulungiswa kwe-Viscosity: I-HPMC ibonisa indlela ye-pseudoplastic, apho i-vinsosity yayo ihla khona ngokukhulisa inqanaba loomasipala. Le ndawo isetyenziswa kwifomu ezahlukeneyo zokulawula indlela yokuhamba kunye neempawu zengqongqo.

Uzinzo lwe-therm: I-HPMC ibonisa uzinzo kuluhlu lobushushu olubanzi lobushushu, lwenze ilungele ukusetyenziswa kwemali efuna ukwenziwa kobushushu okanye ukubonakalisa amaqondo obushushu aphezulu.

I-Intertical Inert Inert, i-HETMC ye-HETMC, ihambelana noluhlu olubanzi lweezongezo, umdlali, kunye nezithako ezisebenzayo ezisetyenziswa ngokuqhelekileyo kwindawo yamayeza kunye nokutya.

3.Synthesis ye-HPMC

I-Synthesis ye-HPMC ibandakanya amanyathelo aliqela:

Unyango lwe-Alkali: I-Seleculose inyangwa ngeAlkali, efana neSodium hydroxide, ukuvelisa ialkali sellulose.

Isiko le-ether

I-Methylity: I-HydroxyPopyPupleted Iselsulose inyangwa nge-methyl chloride ukwazisa amaqela e-Mactsy, ukuvelisa i-HPMC.

Ukucocwa: I-HPMC ephumeleleyo ihlanjululwe ukususa iimveliso kunye nokungcola, ukuqinisekisa umgangatho wemveliso kunye nokungaguquguquki.

Iindlela zokusebenza kwe-HPMC

Ishishini lamachiza: I-HPMC isetyenziswa ngokubanzi njengoyilo lwemigaqo yecwecwe, apho ikhonza njenge-binder, intsholongwane, kunye ne-Arhente yokukhupha i-Arhente. Ikwasetyenziswa kwizisombululo ze-Ophthalmic, iikhrim eziphezulu, kunye nokumiswa komlomo ngenxa ye-bimoMPifeyisi yayo kunye ne-mucomadhees.

Ishishini lokutya: kwishishini lokutya, i-HPMC lisebenza njenge-thi chuker, i-stabilizer, kunye ne-mulsifier kwiimveliso ezahlukeneyo, kubandakanya iisosi, ukunxiba, kunye nezinye iindlela zobisi. Ikwasetyenziswa kwi-bangden-yasimahla yokubhaka njengearhente yokufunda kunye nokukhuthaza umswakama.

Umzi-mveliso wokwakha: I-HPMC ibaluleke kakhulu kwizinto ezikhoyo zesamente, iiplasters, kunye ne-tile. Iphucula ukusebenza ngokukuko, ukugcinwa kwamanzi, kunye nokunamathela, kubandakanya ukusebenza kunye nokuqina kwezixhobo zokwakha.

Iimveliso zononophelo lobuqu: i-HPMC ifakiwe kwi-cosmetics, iimveliso zekhusi, kunye nefomu yokhathalelo lweenwele zokwenza iifilimu, ukuqaqamba, kunye nokwenza ipropathi. Inika ukwenziwa kwengqondo enqwenelekayo, uzinzo, kunye neempawu zemvakalelo kwi-indes, iikhrim kunye ne-Gels.

Ukudibana kunye nokupakisha: Amatyala asekwe kwi-HPMC asetyenziswa kwiitafile zamachiza kunye neecaphus ukuphucula ukuvela, incasa yemaski, kwaye unike ukhuseleko lokufuma. Iifilimu ze-HPMC zikwasetyenziswa kwipakethi yokutya njengokutya okudliwayo okanye izithintelo ngokuchasene nokufuma neoksijini.

I-HydroxyPOpyl Methylcelceltulose i-polymer yezinto ezininzi ezahlukeneyo ngezicelo ezahlukileyo kumashishini. Ukudityaniswa kwayo okhethekileyo yepropathi, kubandakanya ukubenzela amanzi, ukwenziwa kwefilimu, ukulungiswa kwefilimu, kunye nokungazithembi kweekhemikhali, kwenza ukuba ingabaluleki kwiindawo zamayeza, ukutya, ukwakhiwa kweemveliso zononophelo. Ukuqonda ubume, i-synthesis, iipropathi, kunye nokusetyenziswa kwe-HPMC kubalulekile ukuze iifomula kunye nabavelisi babefuna ukudibanisa izibonelelo zayo kuPhuhliso lweMveliso kunye nokuHhlwaya.

Ukubaluleka kwe-HPMC kuxhomekeke kusetyenziso lwayo, ukusebenza, kunye negalelo ekwandiseni intsebenzo, uzinzo, kunye neempawu zemvakalelo zoluhlu olubanzi lweemveliso kumacandelo ahlukeneyo kunye nokusetyenziswa.
