Hydroxypylththththththylcelllose (hpmc) naHydroxyethythythythyth Cellulose (HEC) Ha abụọ heolose meriri, na-ejikarị ụlọ ọrụ, ọgwụ, ọgwụ, ịchọ mma na ubi ndị ọzọ. A na-egosi isi ọdịiche ha na usoro molecular, njirimara solus, ubi akwụkwọ ubi na akụkụ ndị ọzọ.
1. Ihe molecular owu
Hydroxypylththththththylcelllose (hpmc)
HPMC bụ mmiri na-agbanye mmiri site na-ewebata methyl (-ch3) na hydroxypyl (-ch2chohyl (-ch2chohch3) Otu n'ime otu akwara cellular. Kpamkpam, usoro nke HPMC nwere ihe abụọ na-arụ ọrụ, methyl (-Och3) na hydroxyl (-Och2CH (oh) Ch3). Ọtụtụ mgbe, mmeghe ruru nke methyl dị elu, ebe hydroxyyl nwere ike ime ka solublition nke cellose.
Hydroxyethythythythyth Cellulose (HEC)
HEC bụ usoro a na-eweta site na iwebata Ethyl (nke -Ch2chtoh) Otu n'ime akwara cellular. Na nhazi nke hydroxyethyth cellulose, otu ma ọ bụ karịa hydroxy dị iche iche na-edochi otu eriri afọ nke ethyl hydroxy dị iche iche (-ch2CH2OH). N'adịghị ka HPMC, usoro molecular nke hec nwere naanị otu hydroxyethyl na enweghị otu methy.

N'ihi ọdịiche dịgasị iche, mmiri na-esochi hpmc na hEC dị iche.
HPMC: HPMC nwere ezigbo mmiri solubality, karịsịa na ngọpụ pịpụ iche ma ọ bụ ụdị alkaline plọgị, ka ọ dị mma karịa hec. Okwu mmeghe nke methyl na ìgwè hydroxyl na-eme ka onye so ya mee ihe ma nwee ike ịbawanye viscosity site na mmekọrịta ya na ụmụ irighiri mmiri.
HEC: HEC na-egbukarị mmiri, mana onye na-ekwe ya ka ọ dị mma, karịchaa na mmiri oyi, ọ na-abụkarị ndị na-eme ka ọ dị elu ma ọ bụ na-achọ mmetụta dị elu iji nweta nsogbu dị elu iji nweta nsogbu dị elu. Ọ bụ ihe solubality ya na ọdịiche dị iche iche celluse na hydrophilicity nke hydroxyethyl otu.

HPMC: N'ihi ọnụnọ nke otu hydrophilic abụọ dị iche (Methyl na hydroxyl) na-ejikwa ihe ndị na-eme mgbanwe na-agbanwe agbanwe, a na-ejikọ ya na mgbasa ọgwụ na mpaghara. N'oge dị iche iche dị iche iche, Hpmc nwere ike inye mgbanwe site na ọkwa dị ala na viscosity dị elu, na viscosity dị iche iche na mgbanwe plọ.
Enwere ike idozi viscosise nke hec site na ịgbanwe ịta ahụ, mana ọkwa mgbanwe ya dị warara karịa nke HPMC. A na-ejikarị hec na ọnọdụ ebe a chọrọ viscosity dị ala, ọkachasị na owuwu, ihe mgbochi na ngwaahịa nlekọta onwe ya. Njirimara Njirimara nke hec dịtụ mma, ọkachasị na acidic ma ọ bụ gburugburu na-anọpụ iche, hec nwere ike ịnye Visity Ngada mara mma.

5. Kwụsị nkwụsi ike
HPMC: HPMC na-enwe mmetụta dị ukwuu na mgbanwe pch. N'okpuru ọnọdụ acidic, solublity of hpmc mbelata, nke nwere ike imetụta arụmọrụ ya. Ya mere, a na-ejikarị ya na-anọpụ iche na gburugburu alkaline.
HEC: HEC ka dịtụ ọnụ na mbara igwe. O nwere ikike siri ike na gburugburu acidic na alkaline na alkaline, yabụ na-ejikarị ya na-achọ nkwụsi ike siri ike.
HpmcnaHECDị iche na usoro molecular, sosibility, arụmọrụ mgbanwe, na mpaghara ngwa. HPMC nwere ezigbo mmiri sossibility na arụmọrụ viscosity arụmọrụ, ma dịkwa mma maka ngwa chọrọ Victosese ma ọ bụ arụmọrụ ejirikwa nchịkwa dị elu; Ka HEC nwere ezigbo ngwa na ngwa dịgasị iche iche, ma dịkwa mma maka oge chọrọ ọkara na mgbanwe mgbanwe nke gburugburu ebe obibi. N'ime ngwa ahụ, nhọrọ nke ihe nwere mkpa ka a tụleghachi dabere na mkpa ụfọdụ.
