Hydroxypropyl methylcellulose (HPMC)inowanzoshandiswa mvura-soluble cellulose derivative, inoshandiswa zvakanyanya mukuvaka, mishonga, chikafu uye zuva nezuva maindasitiri emakemikari. Muzvivakwa zvekuvaka, kunyanya mumataira anonamira, madziro putties, yakaoma madhaka, etc., HPMC, sechinhu chinowedzera kiyi, haingogadzirisi kuita kwekuvaka, asi zvakare ine kukosha kwakakosha pakubatanidzwa.
1. Zvinhu zvakakosha zveHPMC
AnxinCel®HPMC ndeye cellulose kubva kune yakanaka kunyungudika kwemvura, kunamatira uye kukora mhedzisiro. Iyo inoumba colloid mumvura kuburikidza ne hydroxypropyl uye methyl mapoka mune yayo molecular chimiro, iyo inogona zvinobudirira kuvandudza adhesion, rheology uye kuchengetedza mvura kwezvinhu. Mukuvaka zvinonamatira, kuwedzerwa kweHPMC kunogona kuvandudza simba rekubatanidza, kuwedzera nguva yakavhurika, uye kugadzirisa kupararira uye kuramba kwemvura. Naizvozvo, huwandu hweHPMC hunoenderana zvakananga nekuita kwezvivakwa izvi, izvo zvinozokanganisa hukama hwekubatanidza.
2. Mhedzisiro yeHPMC dosage pakusimba kwekubatanidza
Simba rekubatanidza chiratidzo chakakosha chekuongorora maitiro ekuvaka adhesives. Huwandu hweHPMC hwakawedzerwa kune adhesive hunogona kukanganisa zvakanyanya simba rekubatanidza. Kune rimwe divi, huwandu hwakakodzera hweHPMC hunogona kusimudzira kubatana uye kusimba kwesimende-yakavakirwa zvinhu. Izvi zvinodaro nekuti HPMC inonatsiridza kuchengetwa kwemvura kwedhaka, ichibvumira simende kuti iite zvirinani kuita makemikari neiyo substrate pamusoro panguva yekuomeswa kwemaitiro, nekudaro ichivandudza yekupedzisira yekubatanidza mhedzisiro. Kune rumwe rutivi, kana huwandu hweHPMC huri huduku, kuchengetwa kwemvura kwayo hakuna kukwana, izvo zvingaita kuti simenti irasikirwe nemvura nguva isati yasvika, inokanganisa kuoma kwekugadzirisa uye kukonzera kusagadzikana kwekubatana kwesimba; nepo kana huwandu hwakanyanya, hunogona kuita kuti chinamatira chive chakanyanya kupenya, chinokanganisa mashandiro ekuvaka uye kunyange kukonzera kuderera kwesimba.
Zvidzidzo zvakaratidza kuti huwandu hwakakodzera hweHPMC hunowanzo pakati pe0.5% uye 2%, iyo inogona kunyatso kuvandudza simba rekubatanidza mukati meiyi renji uku uchisimbisa zvimwe zvinhu zvakaita semvura uye kushanda. Nekudaro, iyo chaiyo mari inoda kugadziridzwa zvinoenderana neiyo substrate mhando uye chaiyo application nharaunda.
3. Mhedzisiro yeHPMC dosage pakuita kwekuvaka
Kuita kwekuvaka ndechimwe chezviratidzo zvakakosha zvekuongorora zvinonamira, kunyanya kusanganisira fluidity, nyore kuvaka uye inogadziriswa nguva yekushanda. Huwandu hweHPMC hune mhedzisiro yakakosha pazvinhu izvi. Sezvo huwandu hweHPMC huchiwedzera, viscosity yekunamatira inowedzera, ichiratidza kunamatira kwakasimba uye nguva yakareba yakavhurika. Kunyangwe nguva yakareba yakavhurika dzimwe nguva inogona kunatsiridza kuchinjika kwekuvaka, inogona zvakare kuita kuti nzvimbo yekuvaka inamire kumashure uye kukanganisa iyo bonding mhedzisiro.
Kune mhando dzakasiyana dzema substrates, senge mataira, matombo, madziro, nezvimwewo, huwandu hweAnxinCel®HPMC hunoda kuvandudzwa. Semuenzaniso, mumamiriro ezvinhu apo nguva yakareba yekushanda nekugadzirisa inodiwa, kuwedzera kuwanda kweHPMC zvakakodzera kunogona kuwedzera nguva yakazaruka uye kudzivisa kuoma nokukurumidza, zvichiita kuti kusungirirwa kusina simba. Nekudaro, kana iyo yakavhurika nguva yakarebesa, inogona kukonzera kutsvedza kusingakoshi panguva yekuvaka uye kukanganisa kurongeka kwekuvaka.
4. Mhedzisiro yeHPMC dosage pakuramba mvura uye kusamira kwemamiriro ekunze
HPMC haingogone kuvandudza simba rekubatanidza uye kuita kwekuvaka, asiwo kuvandudza kudzivirira kwemvura uye kuramba kwemamiriro ekunze kweanonamatira. HPMC inovandudza kuchengetwa kwemvura ye simenti, kuitira kuti simende-inonamatira inonamatira irege kurasikirwa nemvura nekukurumidza panguva yekuomeswa kwemaitiro, nekudaro ichiwedzera kudzivirira kwayo kwemvura uye kusagadzikana kwemamiriro ekunze. Kana iyo dosage yeHPMC yakafanira, kuramba kwemvura uye hupenyu hwesevhisi hwechinyorwa hunogona kuvandudzwa zvakanyanya, kunyanya mumadziro ekunze uye munzvimbo dzine hunyoro, uko kushomeka kwemvura kweanonamatira kwakakosha.
Nekudaro, yakawandisa HPMC inogona kutungamira kune yakanyanyisa kukora kweanonamira, kukanganisa kugadzikana kwechimiro chesimende-yakavakirwa zvinhu, uye kuderedza kwayo kuramba kwemvura. Naizvozvo, optimize dosage yeHPMC kuenzanisa iyo hydration uye kushorwa kwemvura kwesimende ndiyo kiyi yekuve nechokwadi chekubatana.
5. Mhedzisiro yeHPMC dosage pane zvimwe zvinhu zvemuviri
Pamusoro pesimba rekubatanidza, kuita kwekuvaka, kuramba kwemvura, nezvimwewo, iyo dosage yeHPMC inozokanganisawo zvimwe zvemuviri zvimiro zvekunamatira. Semuenzaniso, nekuwedzera kweHPMC dosage, kugadzikana kwekunamira kunogona kuvandudzwa nekuti HPMC inogona kuvharira sedimentation uye stratification mune inonamatira uye kuchengetedza yunifomu yemuviri zvimiro. Mukuwedzera, iyo dosage yeHPMCzvakare yakabatana zvakanyanya nezvinhu zvakaita semuvara, anti-slip properties, uye nguva yekurapa yekunamatira. Yakasiyana HPMC dosages inogona kuwana yakanakisa kuita kwemuviri pasi pezvakasiyana zvekuvaka zvinodiwa.
Sekuwedzera kwakakosha pakuvaka zvinonamirwa, AnxinCel®HPMC ine yakakosha kukonzeresa kwekubatana. Chiyero chayo chinoda kugadziridzwa zvinoenderana nezvinodiwa zvekuvaka, substrate maitiro uye mamiriro ezvakatipoteredza. Huwandu hwakakodzera hweHPMC hunogona kunyatso kuvandudza simba rekubatanidza, kuita kwekuvaka, kuramba kwemvura uye kuramba kwemamiriro ekunze, uku uchichengetedza kugadzikana kwakanaka kwemuviri. Nekudaro, yakawandisa kana kusakwana HPMC inogona kutungamira kune isina kugadzikana inonamira zvivakwa uye kukanganisa iyo yekubatanidza maitiro. Naizvozvo, mumashandisirwo anoshanda, zvinodikanwa kuona iyo yakakwana HPMC dosi kuburikidza nekuyedza uye kugadzirisa kuti uwane yakanakira bonding maitiro.
