Kodi pali kusiyana kotani pakati pa hydroxyethyl cellulose ndi hydroxypropyl cellulose?

Hydroxyethylcellulose (HEC) ndi hydroxypropylcellulose (HPC) onse ndi ochokera ku cellulose, polima wachilengedwe wopezeka m'makoma a cellulose. Ma cellulose awa amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe awo apadera.

Kapangidwe ka Chemical:

Hydroxyethyl cellulose (HEC):

HEC imapangidwa pochita cellulose ndi ethylene oxide.
Mu kapangidwe ka mankhwala a HEC, magulu a hydroxyethyl amalowetsedwa mumsana wa cellulose.
Digiri ya m'malo (DS) imayimira avareji yamagulu a hydroxyethyl pagawo la shuga mu tcheni cha cellulose.

Hydroxypropylcellulose (HPC):

HPC imapangidwa pochiza cellulose ndi propylene oxide.
Panthawi ya kaphatikizidwe, magulu a hydroxypropyl amawonjezedwa pamapangidwe a cellulose.
Mofanana ndi HEC, mlingo wolowa m'malo umagwiritsidwa ntchito kuwerengera kuchuluka kwa hydroxypropyl m'malo mwa molekyulu ya cellulose.

chikhalidwe:

Hydroxyethyl cellulose (HEC):

HEC imadziwika chifukwa cha luso lake losunga madzi bwino, ndikupangitsa kuti ikhale chinthu chodziwika bwino pamitundu yosiyanasiyana ya makulidwe ndi ma gelling.
Zimapanga yankho lomveka bwino m'madzi ndikuwonetsa khalidwe la pseudoplastic, kutanthauza kuti limakhala lochepa kwambiri chifukwa cha kumeta ubweya wa ubweya.
HEC imagwiritsidwa ntchito kwambiri popanga mankhwala osamalira anthu, mankhwala, komanso ngati zowonjezera mu zokutira zamadzi.

Hydroxypropylcellulose (HPC):

HPC imakhalanso ndi madzi abwino osungunuka komanso kupanga mafilimu.
Ili ndi mitundu yambiri yogwirizana ndi zosungunulira zosiyanasiyana kuposa HEC.
HPC imagwiritsidwa ntchito nthawi zambiri ngati chomangira pakupanga mankhwala, mankhwala osamalira pakamwa, ndi kupanga mapiritsi.

ntchito:

Hydroxyethyl cellulose (HEC):

Amagwiritsidwa ntchito kwambiri m'mafakitale odzola komanso osamalira anthu ngati chowonjezera mu ma shampoos, mafuta odzola ndi zonona.
Amagwiritsidwa ntchito ngati stabilizer ndi viscosity regulator muzopanga zamankhwala.
Amagwiritsidwa ntchito popanga utoto wamadzi ndi zokutira.

Hydroxypropylcellulose (HPC):

Amagwiritsidwa ntchito pazamankhwala, makamaka ngati chomangira popanga mapiritsi.
Amagwiritsidwa ntchito pazinthu zosamalira pakamwa monga mankhwala otsukira mano chifukwa cha kukhuthala kwake.
Itha kugwiritsidwa ntchito m'machitidwe owongolera operekera mankhwala.

Ngakhale hydroxyethyl cellulose (HEC) ndi hydroxypropyl cellulose (HPC) amagawana zofananira chifukwa cha chiyambi cha cellulose, zimasiyana pamapangidwe, katundu, ndi ntchito. HEC nthawi zambiri imayamikiridwa ndi chisamaliro chaumwini ndi zokutira zopangira mphamvu zosungira madzi ndi kukulitsa mphamvu, pamene HPC imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makamaka pakupanga mapiritsi ndi machitidwe oyendetsedwa operekera mankhwala. Kumvetsetsa kusiyana kumeneku ndikofunikira pakusankha zotumphukira zoyenera za cellulose pazogwiritsa ntchito m'mafakitale.
