Nguwuphi umahluko phakathi kwe-HPMC E5 kunye ne-E15?

I-HydroxyPOpyl Methylcelcelsulose (HPMC) yi-semi-synthetic, i-InErt, i-InErt, i-Vicoelastic Polymer efumana ukusetyenziswa kakhulu kwimizi-mveliso eyahlukeneyo kubandakanya amayeza, ukwakhiwa, ukutya kunye ne-cosmetics. Ithathwe kwi-seluplose ngokuguqula iikhemikhali. I-HPMC iyafumaneka kumabakala ahlukeneyo ebonakaliswa ngumgangatho wokufakwa endaweni ye-hydroxypropy kunye namaqela e-AFGISYS, kunye nohlobo lwe-viscosity yesisombululo. Amabakala acetywayo ngumdibaniso weeleta kunye neenombolo, ezinje nge-E5 kunye ne-E15.

1. Ulwakhiwo lweemolekyuli:
I-HPMC E5:
I-HPMC E5 ibhekisa kwinqanaba le-HPMC kunye nenqanaba eliphantsi lokufakwa endaweni ye-HydroxyPlPLy kunye namaqela e-AFGESSY xa kuthelekiswa ne-E15.
Inqanaba eliphantsi lokufaka endaweni ye-hydroxylpyl kunye namaqela e-AFGISS ngeyunithi nganye kwi-Polymer Chain.
I-HPMC E15:
I-HPMC E15, kwelinye icala, inomgangatho ophezulu wokufakwa endaweni ye-hydroxypropy kunye namaqela e-AFGISY ithelekiswa ne-E5.
Oku kuthetha inani elikhulu le-hydropypy ye-hydropyl kunye namaqela e-APEXGY kwiyunithi nganye kwi-Polymer Chain.

I-2. UVIKILE:
I-HPMC E5:
I-HPMC E5 Ngokwesiqhelo inombala ongezantsi xa kuthelekiswa ne-E15.
Amabakala o-Viscosity of E5 ahlala esetyenziswa xa isiphumo esisezantsi sinqweneleka kwifomu.
I-HPMC E15:
I-HPMC E15 ine-viscofity ephezulu xa kuthelekiswa ne-E5.
Amabakala e-Viscosity ephezulu athanda ukuba i-E15 ithandelwe xa inguqulelo ye-Thicker okanye iipropathi ezingcono zamanzi ziyafuneka kwizicelo.

I-3. Ukuzalwa kwamanzi:
I-HPMC E5:
Zombini i-HPMC E5 kunye ne-E15 zii-polymer zamanzi.
Nangona kunjalo, i-solubity isenokwahluka kancinci kuxhomekeke kwezinye izinto zokwenza kunye neemeko zokusingqongileyo.
I-HPMC E15:
Njenga-E5, i-HPMC E15 inyibilikiswe ngokulula emanzini.
Kuyacaca ukuba icacile, iZisombululo ze-Viscous malunga nokuchithwa.

4. Izicelo:
I-HPMC E5:
I-HPMC E5 ihlala isetyenziswa kwizicelo apho i-viscofity esezantsi kunye nefukuthelo lokuqina eliphakathi lifuneka.
Imizekelo yezicelo ibandakanya:
Ifomu yamayeza (njengababi beebhanti, nabasebenzi, okanye iiarhente zokukhutshwa ezilawulwa).
Iimveliso zononophelo lobuqu (njengamantshontsho kwi-ivoti, iikhrim, kunye ne-shamppoos).
Ishishini lokutya (njengearhente yothutho okanye i-thickener).
Imveliso yokwakha (njengesongezo kwiimveliso ezisekwe kwimo yesamente yokuphuculwa kokusebenza kunye nokugcinwa kwamanzi).
I-HPMC E15:
I-HPMC E15 kukhethwa kwizicelo ezifuna i-viscofity ephezulu kunye neepropathi ezinkulu ezinamandla.
Ukusetyenziswa kwe-HPMC E15 kubandakanya:
Ifomu yamayeza (njengearhente yeGeble, iimodeli zokundwendwela, okanye iiarhente zokukhupha).
Izinto zokwakha (njenge-tickener okanye i-binder eTile Adheves, udaka, okanye griuts).
Imveliso yokutya (njengearhente yokutya e-saus, i-Puddings, okanye iimveliso zobisi).
Imveliso ye-Cosmetic (kwiimveliso ezifuna i-viscofity ephezulu, ezinjengee-geses zeenwele okanye i-mousseling).

I-5. Inkqubo yokwenziwa:
I-HPMC E5 kunye ne-E15:
Inkqubo yokwenziwa kwe-HPMC E5 kunye ne-E15 ibandakanya ukuthunyelwa kwe-telsulose nge-propylene oxide ne methyl chloride.
Inqanaba lokufakwa endaweni lilawulwa ngexesha leSomandla ukufezekisa iipropathi eziyimfuneko.
Iiparameter ezahlukeneyo ezinjengexesha lokuphendula, ubushushu, kunye nomyinge we-repas olungiselelwe ukuvelisa i-HPMC ngeempawu ezithile.

Umahluko ophambili phakathi kwe-HPMC E5 kwaye i-E15 ilele kwisakhiwo sabo seemolekyuli, uVeksisity, kunye nokusetyenziswa. Ngelixa amabakala omabini avela emanzini avela kwi-selulose, i-HPMC E5 inomgangatho ongezantsi kunye nokubonisa ukufakwa kuthelekiswa ne-HPMC E15. Ngenxa yoko, i-E5 ilungele izicelo ezifuna ukugcinwa okuncinci kunye neepropathi eziphakathi, ngelixa i-E15 ikhethiwe kwizicelo ezifuna i-viscofity ephezulu kunye neziphumo zokomelela. Ukuqonda lo mahluko kubalulekile ekukhetheni inqanaba elifanelekileyo le-HPMC ukufumana ifom kunye nokusetyenziswa.
