Ghọta etu HPMC adhosives mụbaa viccosity

Okwu Mmalite:
A na-ejikarị ihe ngosi Hydylcellose (HPMC) mee ihe n'ọtụtụ ụlọ ọrụ dị iche iche, gụnyere owuwu, ọgwụ na nri. Otu n'ime ihe ndị dị mkpa na-eme bụ ikike ha bụ ikike ha ịmụba viccosity, nke dị mkpa maka ịdịmma ha na ngwa dị iche iche.

Nghọta HPMC:
Tupu ị na-abanye n'ime otú HPMC adhosives mụbaa viscosity, ọ dị mkpa ịghọta ihe HPMC bụ ihe Njirimara ya. HPMC bụ solulose derivatized syntehazed si cellose, polymer sitere polymer nke sitere na osisi. A na-ejikarị ya dị ka nke na-eme ihe, sie ike, na emilifier n'ihi ihe nkiri ya dị ezigbo mma na mmachi. HPMC na-adịkarị n'ụdị ntụ ntụ ma nwee ike belata na mmiri iji mepụta ngwọta viow.

Usoro nkwalite nke viscosiment:
Ndozi HPMC na-abawanye viscosis site na ọtụtụ usoro, gụnyere hydration, interntations, na njikọ hydrogen.

Hydration:
Mgbe a gbasasịrị ntụ ntụ hpmc na mmiri, ọ na-aga hydration, ebe ụmụ irighiri mmiri banye na hydroxypyl nathyl dị na HPMC BIN. Usoro a hydection usoro na-eme ka HPMC molecules na-aza, na-eduga na mmụba nke olu na visces nke ihe ngwọta. Ogo nke hydration na-adabere n'ihe dị ka oke molecular na ịta HPMC, yana ọnọdụ gburugburu ebe obibi dịka ọnọdụ na pH.

Ntanetị:
HPMC Molecules bụ ogologo e ji ụdọ nwere oke mgbanwe. Mgbe chụsasịrị ya na mmiri, agbụ ndị a na -akọ ibe ha, na-akpụzi ihe owuwu network nke na-agbapụta usoro nke ihe ngwọta. Dị ka ịta nke HPMC na-abawanye, ọnụ ọgụgụ nke nnabata na-abawanye, na-ebute vicosity dị elu. Ihe mmetụta a na-agagharị a na-akpọ ndị ọzọ na oke molecular nke HPMC.

Hydrogen Njikọ:
HPMC Molecules nwere ọtụtụ hydroxy di iche iche (-OH) tinyere yinye ha, nke nwere ike imekọ ihe eji eme mmiri na ụmụ irighiri mmiri na ibe ha. Agbụ hydrogen ndị a na-atụnye ụtụ na cohesion na nkwụsi ike nke netwọkụ HPMC, na-enwekwu viscosity. Ọzọkwa, hydrogen nke jikọtara n'etiti ụmụ irighiri ihe na ndị ọzọ ihe ndị ọzọ na-eme, dị ka fonsation ma ọ bụ ihe mgbakwunye, nwekwara ike imetụta ndagharị.

Ihe na-emetụta viscosity:
Ọtụtụ ihe na-emetụta viscosity nke hpmc adres ndị, gụnyere:

Ibu Ilucular:
Ibu akwara nke hpmc nke na - emetụta ihe ndị na - eme ka ihe ndị na - eme ka viscosing. Ndị kachasị elu molecular ibu HPMC na-ejikarị ike na ntanetị dị oke mkpa, nke na-ebute ụzọ viscosity dị elu.

Ileta:
The indtụ nke hpmc na usoro nrapado na-emetụta viscosit nke ihe ngwọta. N'ozuzu, nọgide na-eduga na viscosity victose dị elu n'ihi mmụba polymer polymer polymer polymer polymimers na nnabata.

Okpomoku:
Ọnọdụ okpomọkụ nwere ike imetụta hydration na ngagharị nke molecules hpmc na ngwọta. Na mkpokọta, okpomoku dị ala na-akwụsịlata usoro hydration ma belata molecular na-agagharị, na-ebute vicosity dị elu. Agbanyeghị, oke okpomọkụ nwekwara ike imetụta onye na-ekwekọ nke HPMC ma gbanwee omume ya.

PH:
Nke ngwọta ahụ nwere ike imetụta ọnọdụ nke ọrụ ọrụ na HPMC Molecule, si otú ahụ emetụta mmekọrịta ya na molecules na ihe ndị ọzọ na nrapado. Mgbanwe na POT nwere ike imetụta ogo hydration na njikọta hydrogen, yabụ na-agbanwe viscosise.

Ngwa nke HPMC Adresives:
HPMC adhosives chọtara ngwa ndị zuru ebe niile n'ofe ụlọ ọrụ dị iche iche n'ihi Ngwongwo ha na-eme ka ha nwekwuo. Ụfọdụ ngwa ndị a na-etinye:

Ewu:
N'ime ngwa iwu, a na-eji adhesives a na-eme ihe dị ka ihe mgbakwunye na nkụda mmụọ, plasta, na tile adhesives iji mee ka ọrụ dịkwuo ike, njigide mmiri, na ike mmiri. Velite vissetserse na-enyere aka ịkwụsị ịkwagharị ma na-atụfu nrapado n'oge ngwa, na-agba mbọ mkpuchi na nordesion ka mma nke mkpụrụ.

POMMACAKA:
Na nrụpụta ọgwụ, a na-ejizi addesives na-acha ọgwụ ọcha na agba mbadamba, kwụsịtụrụ ma na-achịkwa usoro onunu ogwu. Nleta visc nke HPMC Ngwọta na-arụ ọrụ dị oke mkpa na ịchịkwa oke ọgwụ, na-egbochi mkpu nkụ, ma na-eme ka nkwụsi ike nke usoro.

N'ime ụlọ ọrụ nri, a na-eji adhesive advives dị ka ndị na-eme ihe, na-ekwusi ike na ngwaahịa dị iche iche dị ka sauces, akwa na ihe ụtọ. Visityzọ viscositions nke HPMC na-enyere aka dị mma, a na-edebe ntụ ọka, na nkwụsi ike nke ngwaahịa nri, na-ejide ya na njiri mara mma na njiri mara.

Ihe ngosi Hydroxypyl Methylilose (HPMC) bụ ihe ndị a na-ahụ maka ihe ndị a maara maka ikike ha nwere ịmụba viccosity na menule. Site na ịghọta usoro a na-eme ka nkwalite viscosiment, yana ihe na-emetụta usoro viscosis, ndị na-emepụta nwere ike ịhazi ihe ndị a chọrọ iji rụọ ọrụ, ọgwụ na ụlọ ọrụ ndị ọzọ. Dị ka achọrọ maka ngwa ahịa arụmọrụ dị elu na-aga n'ihu, HPMC na-enweta ihe bara uru bara uru maka Njirimara Viccosite ya na ngwa.
