HydroxyPropyl methylcellose (HPMC) iwanzo cellulose inoshandiswa zvakanyanya mune yekuchenesa zvigadzirwa, inonyanya kushandiswa kugadzirisa vhiza, kugadzikana uye zvimiro zvetsiva zvezvigadzirwa. Nekuwedzera kudiwa kwevatengi kweanobudirira uye zvakatipoteredza kuchenesa zvigadzirwa zvigadzirwa, basa reHPMC muViscosity kudzora kuri kuwedzera uye zvakanyanya kukosha. Nekudaro, maitiro ekunyatsogadzirisa kudzora kweViscosity yeHPMC mune yekuchenesa zvigadzirwa uye optimize chigadzirwa kuita ichiri musoro wakakodzera kudzidza mukudzika.
(1) maitiro ekutanga eHPMC
HPMC ndeyemvura-solulix cellulose cellulose ether ine yakanaka yakanaka, firimu-fomu yekugadzira, kumiswa uye kushanda kwemari. Yayo molecular chimiro ine hydroxyprupyl uye methyl mapoka, ayo anopa iyo yakanaka solubility uye kugadzikana. Mushure meHPMC ichipaza mumvura, inoumba mhinduro inojekesa, iyo inogona kuwedzera mari yekuwedzera iyo visikopa yeiyo yemvura system uye kudzivirira iyo yakanyanya kugadzirwa kwezvikamu zvakasimba, nekudaro ichitamba basa rekusimbisa.
Muzvigadzirwa zvekuchenesa, HPMC inonyanya kushandiswa seanoronga uye viscossity reulator. Inogona kupa zvigadzirwa zvekuchenesa zvakakodzera zvivakwa, zvekuti vane yakanaka yekuvhara uye lubricity panguva yekushandisa. Mukuwedzera, Hpmc ine yakasimba yemunyu uye tembiricha kugadzikana, uye yakakodzera mhando dzakasiyana dzekuchenesa zvigadzirwa zvekuchenesa zvigadzirwa, zvakadai sekudzivirira, ruoko sanitizers, shampoos, etc.
(2) Chimiro chekushandisa cheHPMC mune zvigadzirwa zvekuchenesa
Kuita kwakasimba: HPMC inoumba hydrogen bond network chimiro mune imwe nzvimbo yekukwevera kuti uwedzere vhiza yemhinduro, kugadzira chigadzirwa chekuchenesa kuve nekunzwa kuri nani uye kugadzikana. Semuenzaniso, muZviratidziro, HPMC inogona kubatsira zvinobudirira kuenderana kwechigadzirwa kuti uzvidzivise kubva pakutetepa uye kukanganisa maitiro ekuchenesa. Panguva imwecheteyo, inogona zvakare kuvandudza kuparadzirwa kweiyo destgent uye kuita kuti zvirove zvaro zvemvura mumvura yakawanda yunifomu.
Rheological kutonga: HPMC inogona kugadzirisa iyo rheological zvivakwa zvezvigadzirwa zvekuchenesa, ndiko kuti, kuyerera uye kushambadzira maitiro echigadzirwa mumamiriro ezvinhu akasiyana. Zvakakodzera zvimiro zvakatsanangurwa hazvingangoita chiitiko chechigadzirwa chemushandisi, asi zvakare chinokanganisa kugadzikana kwechigadzirwa panguva yekuchengetedza. Semuenzaniso, HPMC inogona kuchengeta ruoko rwakafanana neruoko pane yakakodzera viscosity pane yakaderera tembiricha yekuzvidzivirira kubva pakuva mutete kana agglomering.
Kumiswa uye STBILICIZIZIKO ZVITSAUKO: Muchenesa Zvigadzirwa zvine zvisizvo zvidimbu, HPMC inogona kudzivirira zvinobudirira zvidimbu kubva kugadzirisa uye kuve nechokwadi chekufanana kwechigadzirwa panguva yekuchengetedza kwenguva refu. Semuenzaniso, mafungidziro anogona kunge aine abrasives kana microparticles. HPMC inowedzera iyo visikopa yehurongwa kuti ive nechokwadi chekuti izvi zvimedu zvakasikwa zvakamiswa mumvura uye kudzivirira kubva kugadziriswa pazasi pebhodhoro.
(3) Matambudziko muHPMC viscossity kudzora
Kunyangwe HPMC ine zvakanakisa muKiscossity Control, pachine zvimwe zvinonetsa mune zvinoshanda zvinoshandiswa, kunyanya mune zvinotevera zvinhu:
Mhedzisiro ye tembiricha dzakasiyana paViscosity: HPMC iri kutarisana neku tembiricha, uye zvavakaita zvichange zvichizorodzwa zvakanyanya pakupisa kwakanyanya, izvo zvinogona kutungamira mukuderera kwechigadzirwa mune mamwe maChigadzirwa ekushandisa mune mamwe maComlication. Semuenzaniso, mune yakanyanya tembiricha yemazhizha muzhizha, kuwirirana kweshanduro inogona kuderera, kukanganisa maitiro ekushandisa.
Mhedzisiro yeIonic Simba pane viscosity: Kunyangwe Hpmc ine imwe yemunyu inogona kushaikwa pasi pezvigadzirwa zvine simba zvine huwandu hwemagetsi, sekushambidza hupfu uye nekuwachira. Mune ino kesi, kugona kwakasimba kweHPMC kunozogumira, zvichiita kuti zviome kuchengetedza viscosity yakagadzikana yechigadzirwa.
Kuchinjisa viscosity panguva yekuchengetedza kwenguva refu: Munguva yekuchengetedza kwenguva refu, visikopa yeHPMC inogona kuchinja, kunyanya pasi pemamiriro ekupisa kukuru uye kusanzwisisika kwekushisa. Shanduko muViscosity inogona kutungamira kuderera mune kugadzikana kwechigadzirwa uye kunyange kukanganisa kuchenesa kwayo uye ruzivo rwemushandisi.
(4) mazano ekuvandudza iyo viscosity kudzora kweHPMC
Kuti vazivise kudzora kweViscosity yeHPMC mune zvigadzirwa zvekuchenesa, matanho akasiyana siyana anogona kutorwa, kubva pakutsvagisa iyo molecular chimiro cheHPMC yekugadzirisa zvimwe zvinongedzo mune formula mune formula.
1. Kugadzirisa iyo molecular chimiro cheHPMC
Iyo viscosity yeHPMC yakanyatsoenderana neyakaomarara uremu uye degree rekutsiva (iyo degree rekutsiva methyl uye hydroxyprupropyl mapoka). Nekusarudza HPMC ine maseru akasiyana madhiza uye madhigirii ekutsiva, maitiro ayo akashata muzvigadzirwa zvakasiyana zvekuchenesa anogona kugadziriswa. Semuenzaniso, kusarudza HPMC ine huremu hukuru hunokwanisa kugadzirisa kusimba kwayo kwekuona kwekusimba kwakanyanya Mukuwedzera, nekugadzirisa danho rekutsiva, kupokana kwemunyu kunogona kuvandudzwa, kuitira kuti inyorese viscosity mune zvigadzirwa zvine magetsi.
2. Uchishandisa yakasarudzika yakakora system
Mune zvinoshandiswa zvinoshanda, HPMC inogona kuumbwa nemamwe manhau kuti azivise simba rayo rakakura uye kugadzikana. Semuenzaniso, kushandisa HPMC pamwe nedzimwe nhambo dzakadai sa xanthan gamu uye carbomer inogona kuwana zvirinani mhedzisiro, uye iyi system yakaomarara inogona kuratidza kusimba kuri nani pane dzakasiyana kupisa, diaonic simba.
3. Kuwedzera solubilizers kana stabilizers
Mune zvimwe zviitiko, iyo solubility uye kusimba kweHPMC inogona kuvandudzwa nekuwedzera solubilizers kana stabilizers kune formula. Semuenzaniso, anowedzera surfers. Mukuwedzera, kuwedzera stabilizers senge ethanol kana preservatives kunogona kuderedza kusvibiswa kweHPMC panguva yekuchengetedza uye kuchengetedza kusarongeka kwekutarisisa.
4. Dzora nzvimbo yekugadzira uye yekuchengetedza
Iyo viscosity yeHPMC inoerera pakushisa uye humidity, saka mamiriro ekunze anofanirwa kudzorwa zvakanyanya sezvinobvira panguva yekugadzira nekuchengetedza. Semuenzaniso, panguva yekugadzira maitiro, nekudzora tembiricha uye nekushomeka, zvinogona kuve nechokwadi chekuti HPMC inodonha uye mitezo iri pasi pekunetseka yekusagadzikana yekusagadzikana inokonzerwa neyakatotsigira zvinhu. Munguva yekuchengetedza, kunyanya mumwaka wakanyanya tembiricha, chigadzirwa chinofanira kudzivirirwa kubva mukufumurwa nenzvimbo dzakanyanyisa kuti dzidzivise zvevasoka zvichikanganisa chigadzirwa hunhu.
5. Kukudziridza Nyowani HPMC DEVIVES
Nekugadziridza kwemakemikari iyo HPMC molecule uye kukudziridza mitsva HPMC inobva Semuenzaniso, kukudziridza HPMC inobva kune yakasimba kupisa uye kurwisa kweElectrolyte kunogona nani kusangana nezvinodiwa zvezvinhu zvakaoma zvekuchenesa zvigadzirwa. Uye zvakare, kusimudzira kweshamwari yemamiriro ekunze uye bioderadable HPMC inodonha ichabatsirawo kuvandudza mashandiro ezvekuchenesa zvigadzirwa uye tevera maitiro aripo wegirazi regirinhi.
Semunhu akakosha akakosha uye viscosity controller, HPMC ine upfu hwakakura kushandisa tarisiro mune zvigadzirwa zvekuchenesa. Nekudaro, nekuda kwekunzwa kwayo kune zvinhu zvakatipoteredza zvinhu zvakadai sekushisa uye ionic simba, matambudziko muHPMC viscossity kudzora kuchiripo. Nekutsvagisa iyo molecular chimiro cheHPMC, ichiwedzera solubilizers kana solubigezers kana stabilizers, uye kudzora mamiriro ezvinhu, iyo viscosity controction yeHPMC mune zvigadzirwa zvekuchenesa zvinogona kuvandudzwa zvakabudirira. Panguva imwecheteyo, nekuvandudzwa kwetsva hpmc inobva
