Dịka ihe arụ dị mkpa, a na-ejikarị ya eme ihe (hpmc) na adhesive, karịsịa n'ọhịa owuwu, ọgwụ, wdg.
Ngwongwo kemịkal na ọrụ nke HPMC
HPMC bụ onyinye ejiri methylcellose mgbe hydropopyyyyyyyyyylation, nke nwere hydrophilicy na ihe ngosi ihe nkiri. Ọ nwere ike melite arụmọrụ nke mkpụrụ site na nsonaazụ kemịkal dị ka hydrolysis na ọzịza. HPMC Molecules nwere otu hydrophilic otu, nke nwere ike itolite mmiri mmiri na mmiri, nke mere na ihe nrapado nwere ezigbo adhesion na mkpuchi. Akụrụngwa kemịkal a na-eme ka ọ rụọ ọrụ nke ọma ma nwee ike ime ka njikọta nke njikọ na ịdị ogologo nke adhasives.
Njirimara anụ ahụ nke hpmc kwalite nrapado
Njirimara anụ ahụ nke hpmc gụnyere mmezi viscittment, njigide mmiri, akpụ ihe nkiri, wdg.
Mgbanwe viscosity: Otu n'ime ọrụ bụ isi nke HPMC na adresives bụ idozi viscosity nke sistemụ ahụ. N'oge dị iche iche, viscosity hpmc na-agbanwe obere, nke na-eme ka mkpuchi nke ụdị nrapado ma dabara adaba na ụdị owuwu dị iche iche. Na mgbakwunye, site na ịhọrọ HPMC ya na oke molecular dị iche iche, rhiology nke nrapado ahụ nwere ike ịchịkwa nke ọma iji gboo mkpa owuwu ihe dị iche iche.
Njikwa mmiri: HPMC nwere akụrụngwa na-egwu mmiri dị iche iche, ọkachasị na nrapade dabere na mmiri. Ọ nwere ike belata mmiri nke mmiri wee mee ka oge gboo nke nrapado, si otú a na-eme ka ọdịmma owuwu. N'otu oge ahụ, ọ nwere ike igbochi mkpụrụ site na ihicha nkụ ma hụ na nkwụsi ike nke ike nke njikọ.
Ngwongwo na-acha akwụkwọ nkiri: HPMC nwere ike ịpụta ụdị fim na-agbanwe agbanwe na siri ike na elu nke mkpụrụ. Ihe nkiri a nwere ike ọ bụghị naanị ịkwalite ike nke nrapado, kamakwa na-enye ezigbo Tunsile ma na-eyi nguzogide, na-eme ka ndọnye aka karịa na ngwa.
Enwere ike iji nsonaazụ: na usoro ihe nrapado, enwere ike iji HPMC mee ihe dị ka onye na-eto eto. Mmetụta nke na-eto eto nke ọma na-eme ka ihe owuwu na akụrụngwa nke nrapado. Karịsịa na ngwa ọdịnala nwere ọdịiche dị elu viscosis chọrọ, HPMC nwere ike ime ka nkwụsi ike nke nrapado ma zere ịba ụba n'oge owuwu.
Ngwa nke HPMC n'ụdị dị iche iche nke adhesives
Enwere ike iji HPMC mee ihe n'ọtụtụ ebe nke adhesives dị iche iche, dị ka nrapade dabere na mmiri, ihe na-agbanwe polymer na nomba ya na-egosi na arụmọrụ nke adresives pụtara ìhè karịchaa.
Ngwa dị na nrapade sitere na mmiri: na nrapade dabere na mmiri, hydrophilicy hpmc na-enyere ya aka ịgbafe ngwa ngwa ma na-etolite sistemụ osisi dị ala. Nke a na - enyere aka ịkwalite ịdị n'otu nke na - adọka mmiri na - egbochi ọdịda n'ihi nkewa ma ọ bụ ịgba nkpu. Na mgbakwunye, njigide mmiri nke hpmc nwere ike inye aka gbasa ndụ nke ihe adhesives na-egbochi mmiri ma zere imetụta mmekọrịta nke njikọ ahụ n'ihi iwechasị ngwa ngwa.
Ngwa na ngwa agha polymer sitere na polymer dabere polymer, HPMC nwere ike ịkwalite njikọ ahụ na ike nke nrapado, ebe na-egwu ọrụ rọrọ, na-eme ka mgbanwe na ịdịgide nke nrapado. Karịsịa na ngwa ụfọdụ chọrọ iguzogide nrụgide ma ọ bụ gburugburu ebe obibi ruo ogologo oge, mgbakwunye nke HPMC nwere ike ime ka ndụ ya dịkwuo elu ma gbasaa ndụ ya.
A na-eji ngwa arụ ọrụ: a na-eji HPMC mee ihe n'ọtụtụ na-arụ ọrụ, tumadi na ngwaahịa dị ka tile adhesives, ntụ ntụ, na ngwa ngwa. N'ụbọchị taịlị, njigide mmiri na mgbanwe mgbanwe nke HPMC nwere ike imezi arụmọrụ nke taịlị, ma belata ihe ize ndụ nke ịma mma na ịpụ apụ. Na ntụ ntụ ntụ na ngwa agha a gwakọtara agwakọta, ụdị ihe nkiri na mmiri nke HPMC nwere ike imeziwanye ịdị larịị na ike nke mkpuchi ma gbochie cracking.
Mmetụta zuru oke nke HPMC na imezi arụmọrụ
Site na nyocha nke ngwa nke HPMC na adhesives, enwere ike ịchọta ya na ọ nwere nnukwu nkwalite nsonaazụ na ọtụtụ igodo igodo nke adhesives:
Meziwanye ike nke ehihie: HPMC nwere ike imeziwanye ike nke njikọ nke adhasives site na ezigbo ụlọ na cohesion, karịsịa na adhesives.
Meziwanye arụmọrụ owuwu: Mmetụta iwu HPMC na Rheological na-eme ka ihe nrapado dị mfe ịrụ ọrụ n'oge owuwu ya na ịzere ịdọpụ na ịpụ. Na mgbakwunye, ihe mkpuchi mmiri ya na-adị ogologo oge nke nrapado, na-eme ka ọ dị mma maka ndị ọrụ ime ụlọ ime mgbanwe ogologo oge.
Meziwanye ogologo: Ihe na-eme ka ihe nkiri dị elu nke Hpmc na-egbochi ihe ndị na-adịghị mma nke nrapado, kamakwa ime ka ndị na-agba mbọ na-emegide ya, na-eguzogide nguzogide na Njirimara ndị ọzọ.
Enyi nke gburugburu ebe obibi: Dika oyuzu sitere n'okike sellulose, Hpmc dị mma na ebe obibi gburugburu ebe obibi. Ọ bụ ihe na-adịghị egbu egbu na ihe na-adịghị emerụ ahụ, ma na-emezu ihe ndị achọrọ gburugburu nchebe gburugburu ebe obibi. Karịsịa na ụlọ ọrụ ụlọ ọrụ ọgwụ nwere ihe nchebe na-ahụ maka gburugburu ebe nchekwa gburugburu ebe obibi gburugburu ebe obibi, ntinye nke HPMC nwere atụmanya sara mbara.
Dịka mgbakwunye, hydroxypyl methylcelllose (hpmc) na-arụ ọrụ dị mkpa na ịkwalite arụmọrụ nke adhasives. A na-eji ya ebe niile na-arụ ọrụ, ngwa agha nke polymer na adres-mmiri site na imezi ike nke njikọ nke adhesives, na-eme ka owuwu owuwu ma na-eme ka ihe owuwu dịkwuo mma. Na mgbakwunye, dị ka ihe ndị metụtara gburugburu ebe obibi, HPMC nwere uru dị elu na atụmanya dị elu. Na mmepe mmepe n'ọdịnihu, na-aga n'ihu ihe ọhụrụ na teknụzụ ọhụụ, ngwa nke HPMC n'ọhịa ga-agbasawanye ma nwekwuo mmụọ.
