Nguwuphi umahluko phakathi kwe-HPMC ye-HPMC ngokukhawuleza kunye nohlobo olushushu olushushu?

I-HPMC (Hydroxypropyl Methylcelcelcelose) yi-ionic selsulose i-Eeser Setherly esetyenziswe ngokubanzi ekwakhiweni, amayeza, ukutya, amachiza emihla ngemihla kunye namanye amakhamidi amachiza. Ngokwendlela yayo yokuchithwa kunye neempawu zesicelo, i-HPMC inokwahlulwa ibe ziintlobo ezimbini: uhlobo oluthile kunye nohlobo olushushu. Kukho umahluko okhoyo phakathi kwaba bobabini ngokwenkqubo yemveliso, iimeko zokuchitha kunye nemeko yesicelo.

1. I-HPMC ye-HPMC

I-HPMC ye-HPMC, ekwabizwa ngokuba luhlobo lwamanzi olubandayo, lunokutshintsha ngokukhawuleza amanzi abandayo ukwenza isisombululo esibonakalayo se-colofal. Iimpawu zayo eziphambili zezi zilandelayo:

1.1. Ukunyibilikisa

I-HPMC ye-HPMC ibonisa ukugcwaliswa ngokugqwesileyo kumanzi abandayo kwaye ichithwe ngokukhawuleza xa ityhilwe emanzini. Inokunyibilikisa ngexesha elifutshane ukwenza isisombululo esilinganayo, ngesiqhelo ngaphandle kwemfuneko yokufudumeza. Isisombululo se-AICOOOO ENCECE sinobala oluhle, uzinzo kunye nokuhlengahlengiswa kohlengahlengiso lwe-viscosity.

1.2. Imeko yesicelo

I-HPMC ye-HPMC isetyenziswa ikakhulu kwiimeko ezifuna ukuchithwa ngokukhawuleza kunye nokuqulunqwa kwesisombululo. Iindawo zokuqhelwa kwezicelo zibandakanya:

Intsimi yokwakha: isetyenziswe njengearhente yokugcina amanzi kunye nearhente yokuthambisa ngenxa yezixhobo ezisekwe kwimo yesamente kunye neemveliso ze-gypsim ukunceda ukuphucula ukusebenza kwezakhi.

Iimveliso zemichiza zemichiza: ezinje ngezicoci, i-shampoos, i-cosmetics, njl njl.

Umzi-mveliso wamachiza: Isetyenziswe njengearhente yefilimu, inamathele, njl njl. Ingachithwa ngokukhawuleza kumanzi abandayo ukuqhuba ukuveliswa kwamalungiselelo.

1.3. Izibonelelo

Iyanyibilikisa ngokukhawuleza kwaye ilungele iimeko zokulungisa ezibandayo.

Kulula ukufaka kunye noluhlu olubanzi lokusebenzisa.

Isisombululo sinobala oluphezulu kunye nokuzinza okuhle.

I-2. I-HOT eshushu i-hpmc

I-HPMC-i-HPMC ye-HPMC, ikwabizwa ngokuba luhlobo olunyibilikayo lwamanzi okanye luhlobo oluzimeleyo, kufuneka luchithiwe ngokupheleleyo kumanzi ashushu, okanye inokufuna ixesha elininzi lokuchithwa kwamanzi abandayo ukuya kutyisa isisombululo. Iimpawu zayo zezi zilandelayo:

2.1. Ukunyibilikisa

Ukuziphatha okungakumbileyo kwe-HPMC eshushu i-HPMC yahluke kakhulu kohlobo lwethutyana. Kumanzi abandayo, i-HPMP eshushu i-HPMC kuphela isasazi kodwa ayinyibiliki. Iya kuphela inyibilikisa kuphela kwaye yenze isisombululo xa ifudumele kubushushu obuthile (ihlala ijikeleze i-60 ° C). Ukuba yongezwa kumanzi abandayo kwaye ivuselelwe ngokuqhubekayo, i-HPMC iya kuthoba amanzi kwaye iqalise ukunyibilikisa, kodwa inkqubo icotha.

2.2. Imeko yesicelo

I-HPMC eshushu i-HPMC isetyenziswa ikakhulu kwiimeko apho ixesha lokutshabalalisa okanye iimeko ezithile zokulungisa i-thermal kufuneka zilawulwe. Iindawo zokuqhelwa kwezicelo zibandakanya:

Izinto zokwakha: njengokwakha izifanisi, izifa ngesandla, njl njl.

Ishishini lamachiza: ezinjengezinto ezihlambulayo zeetafile ezizinzileyo, njl njl.

Umzi-mveliso oqengqelekayo: esetyenziselwa ukubhatalwa kwezicelo eziphantsi kwezinye iimeko ezikhethekileyo zobushushu obukhethekileyo ukuqinisekisa ukwenziwa kwefilimu egqwesileyo kunye nozinzo ngexesha lenkqubo yokwakha.

2.3. Izibonelelo

Inokulibazisa ukupheliswa kwaye ifanelekile kangangezihlandlo ezineemfuno ezizodwa zesantya sokuchitheka.

Thintela ukungavisisani kwamanzi abandayo kwaye unentsebenzo elungileyo yokusasazeka.

Ilungele ukuqhubekeka kwe-thermal okanye usetyenziso apho ulawulo lwenkqubo yokuphelisa iyafuneka.

3. Umahluko ophambili phakathi kohlobo lwethutyana kunye nohlobo olushushu olushushu

3.1. Iindlela ezahlukeneyo zokuchitha

I-HPMMC ye-HPMC: Inokunyibilikisa ngokukhawuleza kumanzi abandayo ukwenza isisombululo esibonakalayo, esilula kwaye sikhawuleze ukusebenzisa.

Ishushu-i-HPMC: Kufuneka ichithwe kumanzi ashushu okanye kufuneka ichithwe ngokupheleleyo kumanzi abandayo ixesha elide, elilungele ezinye iimfuno zokungeniswa kokucotswaniso.

3.2. Umahluko kwimimandla yesicelo

Ngenxa yeempawu zayo zokuchitha ngokukhawuleza, i-HPMC ye-HPMC ilungele iimeko apho isisombululo kufuneka senziwe ngokukhawuleza, njengokwakha nokulungiselela kwemveliso yemichiza yemichiza yemichiza yemichiza. I-HPMC eshushu ye-HPMC isetyenziswa kakhulu kwiimeko apho kufikelela kwindawo yokuhluzwa kweqondo lokungazi-qhinga okanye kwiindawo ezinemilinganiselo yexesha elingqongqo.

3.3. Umahluko kwinkqubo yemveliso

Ngexesha lenkqubo yemveliso, i-HPMC ye-HPMC iguqulwe ngokukhawuleza ukuba inyibilike ngokukhawuleza emanzini abandayo. I-HPMMC yeHPMC igcina iipropathi zayo zokuqala kwaye kufuneka ichithwe emanzini ashushu. Ke ngoko, kwizicelo zokwenyani, kubalulekile ukukhetha uhlobo olufanelekileyo lwe-HPMC ngokweemeko ezahlukeneyo zenkqubo kunye neemfuno zemveliso.

4. Izinto zokuqaphela xa ukhetha i-HPMC

Xa ukhetha ukusebenzisa i-HPME i-HPMC, kufuneka wenze umgwebo ngokusekwe kwiimfuno ezithile zesicelo:

Kwimeko ezifuna ukuchithwa ngokukhawuleza: ezinjengezinto zokwakha ezifuna ukusetyenziswa ngokukhawuleza ngexesha lemveliso, okanye iimveliso zemichiza zemihla ngemihla ezilungiselelwe ngokukhawuleza, i-HPMC yokutsalwa ngokukhawuleza kufuneka ikhethwe.

Kwimeko ezifuna ukuncipha okanye ukulungiswa kwe-thermal: ezinjengokufa, iingubo, okanye iitafile zemveliso ezigcina iziyobisi ezifuna ukukhetha ireyithi, i-HPMC eshushu i-HPMC kufuneka ikhethwe.

Kukho umahluko ocacileyo kwintsebenzo yokuguqula kunye neendawo zokufunda phakathi kwe-HPMC ye-HPMC kunye ne-HPMC. Uhlobo lwethutyana lulungele ukusetyenziswa kwenani elifunwayo, ngelixa uhlobo olukhoyo lulunge ngakumbi kwiimeko ezifuna ukuncipha okanye ukuqhubekeka komoya. Kwizicelo ezithile, ukukhetha uhlobo olufanelekileyo lwe-HPMC kunokuphucula ukusebenza ngempumelelo kunye nokwenza umsebenzi wemveliso. Ke ngoko, kwimveliso yokwenyani kunye nokusetyenziswa, kubalulekile ukuba ukhethe ngokufanelekileyo ukhetho lwe-HPMC ngokusekwe kwiimeko ezithile zenkqubo kunye neemfuno zemveliso.
