Hydroxypropyl methylcelculose (hpmc)

I-3. Ibala lesicelo

3.1​​Intsimi yamayeza

Kumzi-mveliso wamachiza, i-HPMC isetyenziswa ngokubanzi njengento eqinisekileyo yeziyobisi. Ayisetyenziswanga nje njenge-thi cokener, kodwa inokusetyenziselwa ukulungiselela amalungiselelo okuhlela amachiza akhutshiwe. Ukuzenzela amanzi okungaphantsi komhlaba kunye nokuziphatha kwe-biocomatise kwenza isithako esibalulekileyo kumalungiselelo e-chiermaceocial njengamacwecwe, iipilisi kunye neepilisi. Izicelo eziqhelekileyo zibandakanya:

 

Ukukhutshwa kweziyobisi: I-HPMC inokuphefumla kancinci emzimbeni kwaye ikhuphe iziyobisi, ngoko ke ihlala ilungiselela ukukhululwa okuzinzileyo kunye nokulawulwa kwamachiza amachiza.

Umphathi weziyobisi: I-HPMC inokusetyenziswa njengesixhobo sokubumba kunye nokusasazeka xa silungiselela ii-capsules, amacwecwe, amaqhina kunye nezinye iifom zedosi.

I-GEL: I-HPMC inokusetyenziswa njengejeli ukulungiselela iifomu ze-gel zeziyobisi ezahlukeneyo, ezinjengeengcongolo eziphezulu.

 

3.2 Ishishini lokutya

I-HPMC isetyenziswa ngokubanzi kwishishini lokutya, ikakhulu ukuphucula ukuthungwa kokutya, ukwandisa ubomi beshelup, kwaye uphucule incasa yokutya. Izicelo eziqhelekileyo zibandakanya:

 

I-thickener kunye ne-stabilizer: i-HPMC inokusetyenziswa njenge-thickener ekutyeni njengejelly, i-salad, kunye ne-ice cream ukuze kwandise i-viscofity kunye nokuzinza kokutya.

Iarhente yeGelling: Kweendlela ezithile, i-HPMC inokusetyenziswa njengearhente yeqela ukubonelela ngesiphumo sejeyi elungileyo.

Isonka kunye ne-phala: I-HPMC inokuphucula ukungcamla kwesonka kunye ne-pastries, yonyusa ubungozi bazo kwaye inciphise ukomisa ukutya.

 

3.3 Imveliso yokwakha

I-HPMC isetyenziswa ikakhulu njengearhente yokwakha amanzi kunye nokugcina amanzi okwenza izinto ezinje ngengubo, i-gypsum, kunye nepeyinti kwishishini lokwakha, kwaye zihlala zisetyenziswa kule miba ilandelayo:

 

Udaka: I-HPMC inokuphucula umbethe, ukugcinwa kwamanzi kunye nokugcwala kodaka, kunye nokuphucula ukusebenza kolwakhiwo lodaka.

I-Tile Adhesive: I-HPMC inokuphucula ukusebenza kwe-tile ye-tile kunye nokuphucula uxanduva lwayo.

Ipeyinti: ukusebenzisa i-HPMC kwipeyinti kunokunyusa i-viscofity kunye nokuzinza kwepeyinti, kwaye kuncedise ukulawula inqanaba lepeyinti.

 

3.4 Ishishini le-cosmetics

In cosmetics, HPMC is mainly used as a thickener, emulsifier and film-forming agent, and is widely used in products such as creams, facial cleansers, hair sprays, and eye shadows. Imisebenzi yayo ibandakanya:

 

I-thickener: i-HPMC inokunyusa i-viscofity ye-cosmetics kwaye iphucule iimvakalelo zokusetyenziswa.

I-mostiurizer: i-HPMC ineepropathi ezintle kwaye inokunceda ukutshixelwa komswakama ukugcina ulusu lusitsho.

I-Emulsifier: I-HPMC inokunceda amanzi kunye neoyile yomxube ukwenza i-emulsion efanelekileyo.

 

4. Izibonelelo kunye nohlalutyo lwezinto ezingalunganga

4.1 IZIBONELELO

I-biocomatiby elungileyo: i-HPMC yimveliso ye-seluplose yendalo, ihlala ingenatyhefu kwaye ingenabungozi emzimbeni womntu, kwaye ine-biomatise elungileyo.

Ukungabi nako ukungcungcutheka kunye ne-odolf: i-HPMC ihlala ingenalo ivumba okanye icaphukise kwaye ilungele ukutya kunye namayeza.

Isetyenziswe ngokubanzi: Ngenxa yokungabinamali kwawo amanzi, ukuthamba kunye nokuzinza, i-HPMC isetyenziswa ngokubanzi kumashishini amaninzi.

 

4.2 Izinto ezingalunganga

Uzinzo olugwenxa kubushushu obuphezulu: Nangona i-HPMC inozinzo oluhle lobushushu, ukufudumeza kwexesha elide phantsi kweemeko zobushushu obuphezulu kuya kubangela ukuba i-hydrolyze kwaye ikhuphe imisebenzi yayo.

Ixabiso eliphezulu: xa kuthelekiswa nezinye iitriki, i-HPMC ibiza kakhulu, enokuthi inciphise ukusetyenziswa kwayo kwizicelo ezithile.
