Uyini umehluko phakathi kwe-HPMC E5 ne-E15?

I-Hydroxypropyl Methylcellulose (HPMC) yi-semi-zokwenziwa, inert, i-viscoelastic polymer ethola ukusetshenziswa okubanzi emikhakheni ehlukahlukene kufaka phakathi amakhambi, ukwakhiwa, ukudla kanye nezimonyo. Kuthathwe kusuka ku-cellulose ngokusebenzisa ukuguqulwa kwamakhemikhali. I-HPMC iyatholakala kumabanga ahlukene abonakala ngezinga lokufakwa esikhundleni (DS) weHydroxypropylyl kanye namaqembu we-methoxy, kanye nokubonakala kwesixazululo. Amamaki aboniswa inhlanganisela yezinhlamvu nezinombolo, njenge-E5 ne-E15.

1. Isakhiwo samangqamuzana:
I-HPMC E5:
I-HPMC E5 isho ibanga le-HPMC nge-degree ephansi yokufakwa esikhundleni se-hydroxypropyl kanye namaqembu we-methoxy kuqhathaniswa ne-E15.
Izinga eliphansi lokufaka esikhundleni libonisa ama-hydroxyproppropyl kanye namaqembu we-methoxy ngeyunithi ye-cellulose ku-polymer chain.
I-HPMC E15:
I-HPMC E15, ngakolunye uhlangothi, inezinga eliphakeme lokufaka esikhundleni se-hydroxypropyl kanye namaqembu we-methoxy kuqhathaniswa ne-E5.
Lokhu kusho inani elikhulu le-hydroxypropyl kanye namaqembu we-methoxy ngeyunithi ye-cellulose ngayinye ku-polymer chain.

2. I-Viscosity:
I-HPMC E5:
I-HPMC E5 imvamisa inokubona okuphansi okuqhathaniswa ne-E15.
Amamaki we-viscositi angaphansi afana ne-E5 asetshenziswa kaningi lapho umphumela wokuqina ophansi ufiswa ekwakhiweni.
I-HPMC E15:
I-HPMC E15 ine-viscosity ephezulu uma iqhathaniswa ne-E5.
Amamaki aphezulu aphezulu afana ne-E15 ayakhethwa lapho kunconyelwa ukuguquguquka okukhulu noma izakhiwo ezingcono zokugcina amanzi ziyadingeka kuzinhlelo zokusebenza.

I-HPMC E5:
Zombili i-HPMC E5 ne-E15 zingama-polymers ancibilikayo amanzi.
Kodwa-ke, i-solubity ingahlukahluka ngokuya ngezinye izinto ezakhayo kanye nezimo zezemvelo.
I-HPMC E15:
Njengo-E5, i-HPMC E15 iyancibilika kalula emanzini.
Kwakha izixazululo ezicacile, ezibonakalayo lapho kuchithwa.

4. Izicelo:
I-HPMC E5:
I-HPMC E5 ivame ukusetshenziswa kuzinhlelo zokusebenza lapho i-viscosity ephansi kanye nomphumela wokuqina olinganiselayo.
Izibonelo zezicelo zifaka:
Izakhi zemithi (njengezixhumanisi, ukuhlukahlukana, noma ama-ejenti alawulwa alawulwa).
Imikhiqizo yokunakekelwa komuntu siqu (njengama-sikhulu ku-lotion, okhilimu kanye nama-shampoos).
Imboni yokudla (njenge-ejenti yokuhlanganisa noma isikhulu).
Imboni yezokwakha (njengesengezo emikhiqizweni esekwe kuthusi yokusebenza okuthuthukile nokugcinwa kwamanzi).
I-HPMC E15:
I-HPMC E15 iyakhethwa kwizicelo ezidinga ukubonakala okuphezulu kanye nezakhiwo ezinamandla eziqinile.
Izicelo ze-HPMC E15 zifaka:
Izakhi zemithi (njengama-ejenti ama-gelling, ama-viscosity modifariers, noma ama-ejenti wokukhipha okuqhubekayo).
Izinto zokwakha (njengomuntu omkhulu noma i-tinder kuma-tile anamathela, udaka, noma ama-grouts).
Imboni yokudla (njenge-ejenti ekhuthele kusoso, ama-puddings, noma imikhiqizo yobisi).
Imboni yezimonyo (emikhiqizweni edinga ukubonakala okuphezulu, njengeGels Yezinwele noma ama-mousling sting).

5. Inqubo Yokukhiqiza:
I-HPMC E5 ne-E15:
Inqubo yokukhiqiza ye-HPMC E5 ne-E15 ifaka ukuthengwa kwe-cellulose nge-propelene oxide ne-methyl chloride.
Izinga lokufaka esikhundleni lilawulwa ngesikhathi sokuhlanganiswa ukufeza izakhiwo ezifiselekayo.
Amapharamitha ahlukahlukene anjengesikhathi sokuphendula, izinga lokushisa, kanye nesilinganiso sabaphendulwa balungiselelwe ukukhiqiza i-HPMC ngezimpawu ezithile.

Umehluko omkhulu phakathi kwe-HPMC E5 ne-E15 alele esakhiweni sabo samangqamuzana, ukubonakala kanye nezicelo. Ngenkathi womabili amamaki ama-polymers ancibilikayo asuselwa ku-cellulose, i-HPMC E5 inesilinganiso esiphansi sokufakwa esikhundleni kanye ne-viscosity ngokuqhathaniswa ne-HPMC E15. Ngenxa yalokho, i-E5 ilungele izinhlelo zokusebenza ezidinga ukubonakala okuphansi kanye nezakhiwo ezilinganiselwe zokuqina, kanti i-E15 ilindelwe izicelo ezidinga ukubonakala okuphezulu nemiphumela enamandla kakhulu. Ukuqonda lo mehluko kubalulekile ekukhetheni ibanga elifanele le-HPMC yokwenziwa okuthile kanye nezicelo.
