Hydroxypropyl methylcellulose (hpmc) ndi ma cellulose osungunuka a ionic ense ogwiritsidwa ntchito kwambiri pomanga, mankhwala, chakudya, zodzola komanso mafakitale. Makhalidwe a Visccous of the Aquanous yankho lake ndi zinthu zofunika kwambiri zomwe zimakhudza ntchito yake.
1. Makhalidwe oyambira a HPMC
Hulcentl ®hpmc ndi mankhwala opatsirana pa cellulose poyambitsa hydroxypropyl ndi magulu a methyl mu makelo a maselo a cellulose. Ili ndi madzi abwino osungunuka komanso mafayilo akuluakulu, ndipo nthawi zambiri amagwiritsidwa ntchito pokonzekera zothetsera matenda am'madzi. Makhalidwe amenewa amapangitsa HPMC mwamphamvu kwambiri pakulankhula, zomata, kusungidwa ndi mankhwala, zowonjezera zakudya ndi mafakitale ena.
2. Makhalidwe a Viccome a HPMC Aquaous yankho
Makhalidwe a Viccclo a HPMC Aquaus amakhudzidwa ndi zinthu zingapo, makamaka kuphatikiza, kutentha, kukwera mtengo, ph mtengo wamtengo wapatali.
Zotsatira za kukhazikika kwa kukweza
Makutu a HPMC am'madzi a HPMC imachulukana ndi kuchuluka kwa chidwi. Pamene ndende ya HPMC ili yotsika, yankho la madzi ndi loonda ndipo limakweza mafayilo otsika; Pamene chidwi chachikulu chimawonjezeka, kulumikizana pakati pa mamolekyules kumawonjezeka, ndipo mafayilo am'madzi amawonjezeka kwambiri. Nthawi zambiri, mafayilo a hpmc solution ndi okhudzana ndi chidwi chake, koma chimakhala chokhazikika m'malo ena, akuwonetsa mawonekedwe a mafayilo a yankho.
Zotsatira za kutentha pa mafayilo
Kutentha ndi chinthu chofunikira chomwe chikukhudza mafayilo owoneka bwino. Kutentha kwa kutentha kumakwera, kulumikizana kwa hydrophn ndi zogwirizana ndi mamolekyu a HPMC zimafooketsa, zomwe zimapangitsa kuchepa kwa mphamvu yomanga pakati pa mamolekyulu, potero kuchepetsa ma vincy a yankho. Nthawi zambiri, mafayilo a hpmc am'madzi a HPMC amaonetsa chizolowezi chowonjezereka ndi kutentha kwambiri, makamaka kutentha kwambiri. Khalidwe ili limapangitsa HPMC kukhala ndi kuthekera bwino kwamayendedwe owongolera kutentha.
Zotsatira za kumeta ubweya pa mafayilo
Njira yothetsera HPMC imawonetsa mawonekedwe a Newtonia amadzimadzi otsika pamitengo yotsika, ndiye kuti, mafanowo ndi okhazikika; Komabe, kuchuluka kwa mitengo ya High Shear, mawisa a HPMC solumu kutsika kwambiri, kuwonetsa kuti ali ndi misala. Ma molekyulu a HPMC ali ndi zoopsa zina. Mitengo yotsika ya Shear, unyolo umapotozedwa kwambiri, ndikupanga kukana kwakukulu, komwe kumawonekera ngati mamasukidwe apamwamba; Pamathanthwe apamwamba, maunyolo amatambasula, madzimadzi amalimbikitsidwa, ndipo ma virucy amachepetsa.
Zotsatira za mtengo wa pH pa mafayilo
Njira yothetsera HPMC nthawi zambiri imasunga mafayilo okhazikika osalowerera ndale za alkalinine. Mu acid acid kapena malo olimba a acid, hpmc molekyulu imatha kuchitika chifukwa chosintha, chifukwa cha kusintha kwa hydrophicity ndi kuphatikizika kwa mamolekyules a njira yamadzi am'madzi. Nthawi zambiri, kusintha mu p p p p pH imathandiza kwambiri mafayilo a HPMC, koma pamapeto a Ph, kusintha kwa mafayilo kungakhale kowonekera kwambiri.
Zotsatira za mawonekedwe a ma vinya
Makhalidwe a Viscclocs a HPMC amagwirizana kwambiri ndi kapangidwe kake. Mulingo wazolowa m'malo mwa hydroxypyl ndi magulu a methyl mu molekyulu amakhala ndi mphamvu pa mafayilo a funguous. Kukwera kwambiri kwa gawo la gululi, lamphamvu la hydrophilicity ya HPMC ndi kukweza kwa njira yothetsera vutoli. Kuphatikiza apo, ma molecular kulemera kwa HPMC ndi chinthu chofunikira chomwe chikukhudza ma visction. Chokulirapo kunenepa kwambiri, kutalika kwa ma molecular, komanso kulimba pakati pa mamolekyulu, zomwe zimapangitsa kuti mamasukidwe apamwamba a yankho la madzi.
3. Kutanthauza mawonekedwe a mafayilo a HPMC Aquaous yankho pakugwiritsa ntchito
Makhalidwe a ViccCence of HPMC Aquaous yankho ndikofunikira pakugwiritsa ntchito kwake m'magawo osiyanasiyana.
Gawo Lomanga: HPMC imagwiritsidwa ntchito mu matope ndi zomata za simenti ndi zomata, ndipo zimagwira ntchito yamphamvu, kusunga chinyezi, komanso kukonza magwiridwe antchito. Makhalidwe ake amapezeka mwachindunji amakhudzanso kugwirira ntchito ndi kutsatira matope. Mwa kusintha kapangidwe ka HPMC, kayendedwe ka HPMC, zaubweya zaubweya zimatha kuwongoleredwa, potero kumawongolera mosavuta.
Makampani ogulitsa mankhwala: Madencence ycaly ycally nthawi zambiri amagwiritsidwa ntchito pokonzekera ma pokonzekera mankhwala osokoneza bongo, kutulutsidwa zipolopolo, ndi madontho amaso. Makhalidwe ake amatha kukhudza kuti kumasulidwa kwa mankhwala osokoneza bongo ndi kuwongolera mankhwalawa m'thupi. Posankha HPMC yokhala ndi kulemera koyenera komanso kuchuluka kwa kulowetsa, mawonekedwe omasulira mankhwalawa amatha kusinthidwa kuti akwaniritse zotsatira zoyenera kuchita.
Makampani ogulitsa zakudya: HPMC imagwiritsidwa ntchito ngati thicker, rukanitse, ndi emulsifier mu chakudya. Makhalidwe a ViscCon of Aqueous yankho lake limakhudza kukoma komanso kukhazikika kwa chakudya. Mwa kusintha mtundu ndi kuchuluka kwa hpmc yomwe imagwiritsidwa ntchito, kapangidwe ka chakudya kumatha kuwongoleredwa moyenera.
Makampani odzikongoletsa: hpmc, monga kukula ndi kukhazikika kwa zodzoladzola, kumatha kukonza kapangidwe kazinthu, kumazipatsa madzi abwino komanso kumverera bwino. Makhalidwe ake a ViccCon amakhala ndi chofunikira kwambiri pa zomwe wogwiritsa ntchito amapanga zinthu monga zowonera, ma gelos, ndi shampoos.
Machitidwe aHpmc Mankhwalawa amadzi amakhudzidwa ndi zinthu zambiri monga kuphatikizira, kutentha, kukwera mtengo, pH yamtengo, komanso kapangidwe kake. Posintha zinthuzi, ntchito zomwe zimagwiritsidwa ntchito kwa HPMC zitha kuthandizidwa kuti mukwaniritse zosowa za mafakitale osiyanasiyana chifukwa chazomwe zimachitika. Kafukufuku wakuya pakusintha kwa HPMC Aquaous samangothandiza kumvetsetsa zoyambirira zake, komanso amapereka chitsogozo chambiri kuti agwiritse ntchito mwanzeru.
