Hydroxypropyl methylcelculose (hpmc)Yindlela eguqulweyo ye-chemose yeselfowuni esetyenziswa ngokubanzi kwimizi-mveliso eyahlukeneyo efana ne-chimuceuticals, imveliso yokutya kunye nolwakhiwo. Yindawo yokuhambahamba, ihlala isetyenziswa njenge-gickener, i-binder, iarhente yefilimu, kunye nokuzinzisa. Nangona kunjalo, ayinayo inombolo ethile "ye-serial" kwingqondo yesiko, njengemveliso okanye inombolo yenxalenye unokufumana kwezinye iimeko zokuvelisa. Endaweni yoko, i-HPMC ichongwe ngesakhiwo sayo sekhemikhali kunye nenani leempawu, ezinje ngenqanaba lokufaka endaweni kunye novimba.
Ulwazi ngokubanzi malunga ne-hydroxypropyl methylcelcelcelsulose (hpmc)
Isakhiwo sekhemikhali: I-HPMC yenziwa ngokutshintsha imichiza ngokusebenzisa amaqela e-hydroxyl (---o) ene-hydroxypropyl kunye namaqela e-methyl. Ukutshintsha endaweni yokutshintsha iipropathi zeselutise, esenza inyibilikiswe ngakumbi emanzini kwaye kuyiphathele ipropathi eyahlukileyo njengokuphuculwa kwevidiyo ephuculweyo yefilimu, amandla okubopha, kunye nokukwazi ukugcina umswakama.
Izikhombisi eziqhelekileyo kunye neMeming
Ukuchongwa kwe-hydroxypropyl methylcelcelselse ixhomekeke kwiingqungquthela ezahlukeneyo zokuchaza ubume bayo kunye neepropathi:
Inombolo ye-CAS:
Inkonzo ye-Affic Affict (i-CASS) inika isikhombisi esahlukileyo kuyo yonke impahla yemichiza. Inombolo ye-CAS ye-hydroxypropyl methylcelcelose yi-9004-65-3. Eli linani elimiselweyo elisetyenziswa ziingcibi, abathengisi, kunye namaziko olawulo ukubhekisa kwinto.
I-Inchi kunye neekhowudi ze-smiles:
I-Inchi (isibonisi semichiza yehlabathi) yenye indlela yokumela ubume bemichiza yento. I-HPMC inokuba nentambo ende ye-Inchi emele ubume bayo bemolekyuli ngendlela emiselweyo.
Uncumo (inkqubo elula yemolekyuli yemolekyuli) yenye inkqubo esetyenziselwa ukumela iimolekyuli kwifom yesicatshulwa. I-HPMC ikwanayo nekhowudi ehambelana ne-smoids, nangona iya kuba nzima kakhulu ngenxa yendlela enkulu neguquguqukayo yesakhiwo sayo.
Inkcazo yemveliso:
Kwintengiso yezorhwebo, i-HPMC ihlala ichongwa ngeenombolo zemveliso, ezinokwahluka ngomenzi. Umzekelo, umthengisi usenokuba nenqanaba elinjenge-HPMC K4m okanye i-HPMC E15. Ezi zikhombisi zihlala zibhekisa kwi-polymer yesisombululo kwisisombululo, ezigqitywe ngumgangatho wemitha kunye ne-hydroxyypropy kunye nobunzima bemolekyuli.
Ibanga eliqhelekileyo le-hydroxypropyl methylcelculose (hpmc)
Iimpawu ze-Hydroxypropyl Methylcelcelcelsulose Vary ngokusekwe kwinqanaba lokufakwa endaweni ye-methyl kunye namaqela e-hydroxypropy, kunye nobunzima bemolekyuli. Ezi hluko zichonga i-HPMMC's Viscofity kunye noSolubiality emanzini, ezichaphazela izicelo zayo kumashishini ahlukeneyo.
Apha ngezantsi kukho itafile ecacisa amabakala ahlukeneyo e-Hydroxly Gothylceluplose:
| Ibanga | I-Viscosity (CP kwi-2% yesisombululo) | Izicelo | Inkcazo |
| I-HPMC K4m | I-4000 - i-6000 CP | Ithebhulethi yamachiza, ishishini lokutya, ulwakhiwo (amachaphaza) | Ibanga eliphakathi le-viscosity, isetyenziswa ngokuqhelekileyo kwifom yetafile yomlomo. |
| I-HPMC K100m | I-100,000 - i-150,000 cp | Ifomu elawulwa-elawulwayo kwiindawo zamachiza, ukwakhiwa, kunye neepeyinti zepeyinti | I-viscofity ephezulu, ilungele ukukhululwa kwamachiza. |

| I-HPMC 2910 | I-3000-6000 CP | I-cosmetics (i-crems, i-lotions), ukutya (i-confectionery), amayeza (i-capsules (i-capsules, iingubo) | Elinye lawona mabanga aqhelekileyo, asetyenziswe njengearhente yokuzinzisa kunye nokuziqhelanisa nokuziqhelanisa. |
| I-HPMC 2208 | I-5000 - i-15000 CP | Isetyenziswe kwisamente kunye nokuqulunqwa kwesamente, amabali, amaphepha ephepha | Kulungile kwizicelo ezifuna iipropathi ezifanelekileyo zefilimu. |
Ubume obuphezulu kunye neepropathi ze-HPMC
Iipropathi zomzimba ze-hydroxypropyl methylcelcellulose ixhomekeke ikakhulu kubungakanani bokufakwa endaweni yamaqela e-hydroxyl kwimolekyuli. Nazi iipropathi ezinkulu:
Inqanaba lokufakwa endaweni (DS):
Oku kubhekisa ukuba mangaphi amaqela e-hydroxyl kwi-sellutase sele endaweni ye-methyl okanye amaqela e-hydroxypropyl. Inqanaba lokufaka I-DS eqhelekileyo ye-HPMC isuka kwi-1.4 ukuya kwi-2.2, kuxhomekeke kwibakala.
I-Viskosity:
Amabakala e-HPMC ayahlulwa ngokusekwe kuhlobo lwabo lwe-viscosity xa inyibilikisiwe emanzini. Ukuphakama kwesisindo semolekyuli kunye nenqanaba lokufaka endaweni, ukuphakama kwe-viscosity. Umzekelo, i-HPMC K100m (i-vistasity ephezulu ye-viscosity) ihlala isetyenziswa ekuqinisekisweni kweziyobisi, ngelixa amabakala e-HPMC K4m esetyenziswayo kwi-binders yetafile kunye nokusetyenziswa kokutya.
I-Solity yaManzi:
I-HPMC inyibilikiswa emanzini kwaye iyenza into efana nejeli xa inyibilikisiwe, kodwa iqondo lobushushu kunye ne-pH linokuphembelela isolula. Umzekelo, kumanzi abandayo, iyanyibilikisa ngokukhawuleza, kodwa ukuntywila kwalo kungancitshiswa emanzini ashushu, ngakumbi kumacala aphezulu.
Isakhono sokwenza ifilimu:
Enye yeempawu eziphambili ze-hydroxypropyl methylcelcelose kukukwazi ukwenza ifilimu eguqukayo. Le ndawo iyenza ilungele ukusetyenziswa kwetayinti yetafile, apho ibonelela ngendawo egudileyo, elawulwayo. Ikwaluncedo nakumzi-mveliso wokutya ukuphucula ukuqulunqwa nobomi beshels.
I-GEAT:
Kugxininiso oluthile kunye nobushushu, i-HPMC inokwenza i-galls. Le ndawo iluncedo kwifomu yamayeza, apho isetyenziselwa ukwenza iinkqubo zolawulo.
Izicelo ze-hydroxypropyl methylcelcelcelose
Ishishini lamachiza:
I-HPMC isetyenziswa njenge-binder kwifomu yecwecwe, ngakumbi ukukhutshwa okwandisiweyo kunye neenkqubo ezilawulwa-zilawulwa. Ikwasebenza njenge-arhente yokuhamba kweetafile kunye neecaphus ukulawula ukukhutshwa kwesithako esisebenzayo. Amandla ayo okwenza iifilimu ezizinzileyo kunye ne-Gels ilungele iinkqubo zokuhambisa iziyobisi.
Ishishini lokutya
Kwishishini lokutya, i-HPMC isetyenziswa njengearhente yokuthambisa, i-eulsifier, kunye nokuzinza kwiimveliso ezahlukeneyo, kubandakanya neesosi, ukunxiba, kunye nezinto ezibhakiweyo. Inceda ukuphucula ukuthungwa kwaye kwandise ubomi beshels ngokunciphisa ilahleko yokufuma.
I-Cosmetics kunye noKhathalelo loMntu:
I-HPMC isetyenziswa ngokubanzi kwi-cosmetics, apho isebenza njenge-thi churener kunye ne-sticker kwikhrim, i-lotions, ishampu, kunye nezinye iimveliso zononophelo. Ukukwazi kwayo ukwenza umsebenzi wejeli kubaluleke kakhulu kwezi zicelo.
Ishishini lokwakha:
Kumzi-mveliso wokwakha, ngakumbi kwisamente kunye nokuqulunqwa kwesamente, i-HPMC isetyenziswa njengearhente yokugcina amanzi. Inceda ukuphucula ukusebenza kunye nokuphucula iipropathi zezinto eziqhutywa zizixhobo.
Ezinye iinkqubo:
I-HPMC ikwaqeshwa kwishishini lendwangu, ikhredithi yephepha, kunye nokuveliswa kweefilimu ezinokutsha.
Hydroxypropyl methylcelculose (hpmc)yindawo eguquguqukayo esetyenziswayo kumashishini amaninzi ngenxa yepropathi yayo eyahlukileyo efana nesakhono sokwenza ifilimu, amandla okutsala, kunye nokugcinwa kwamanzi. Ngelixa ingenayo "inombolo ye-serial" kwingqondo eqhelekileyo, ichongwa nge-imeyile yeekhemikhali njengenani layo (i-9004-65) kunye namabakala emveliso (umz, i-HPMC ye-E4M). Uluhlu lwe-HPMC lwamabakala afumanekayo luqinisekisa ukuqhutywa kwemali kwimimandla eyahlukeneyo, ukusuka kwiindawo zamayeza ukuya ekutyeni, amayeza kunye nolwakhiwo.
