HydroxyPropyl methylcellose (HPMC) inzvimbo yeClongnictional inoshandiswa zvakanyanya mumasango akasiyana siyana kusanganisira kuvaka. MuPutty mafomu, Hpmc inoshumira mabasa akasiyana siyana, kusanganisira kusimudzira kugona, kuvandudza kudenha, kudzora kuchengetwa kwemvura, uye kururamisa michina.
Forty formation inoita basa rakakosha mukuvaka sechinhu chose chechinyorwa chinozadza mapundu, zvakatsiga nzvimbo, uye chinopa nyangwe kana zvisizvo zvekupenda. HydroxyPropyl methylcellose (HPMC) ndeimwe yeiyo yakakosha zvinoshandiswa zvinoshandiswa mune putty mafomu nekuda kwezvinhu zvaro zvakasarudzika uye zvinoshamisa.
1.HPMC makemikari zvivakwa
Hydroxypronylmethylcellose ndeye semi-synthetic polymer inotorwa kubva ku cellulose. Iyo inoratidzirwa nechimiro chayo chakasarudzika, chinosanganisira cellulose maketani ane hukama nehydroxypruppropyl uye methyl mapoka. Dhigirii rekutsiva kwemapoka aya inosarudza zvinhu zveHPMC, kusanganisira solubility, viscosity uye kugona kwemafirimu. Kazhinji, HPMC inoshandiswa muPutty mafomu anowanikwa mune yepakati kune yakakwira viscosity mamakisi anopa iyo inodiwa rheological zvivakwa.
2. Mashandisirwo echiito chePutty formula
Kuvandudza Kubata
HPMC inoita seanotenda uye rheology modifier yekuvandudza basa rekushanda kwekutyisa. Iyo polymer mamorekuru emamolekle uye gadzira matatu-dimensional network, iyo inopa viscosity uye inodzivirira zvimedu zvakasimbiswa kubva kugadziriswa. Izvi zvinovimbisa kunyange kugovera uye kushanda nyore kweiyo putty, kuchibvumira kupararira uye kuumba zvakanyatsonaka pasina kuderera kana kudonha.
Kuvandudza Dhiziri
ADHesion inzvimbo yakakosha mune zvekupfeka mafungidziro sezvazvinosimbisa simba rechisungo pakati peiyo putty uye substrate. HPMC inosimudzira kushamwaridzana nekugadzira firimu rakatetepa pane substrate pamusoro, kusimudzira mechanical kukanganisa uye kuwedzera nzvimbo yekuonana pakati pekutya uye substrate. Pamusoro pezvo, iyo hydrophic chimiro cheHPMC inobvumira kuti ifambe nePutty Matrices uye Substrates, inosimudzira kuderedza kunyange panzvimbo dzakaoma.
Mvura Kuchengeta Kudzora
Kuchengetwa kwemvura kuri kutsoropodza kurapwa kwakaringana uye kuomesa kwekufungidzira. HPMC inoita semvura inochengetedza mumiririri nekunyora uye kuchengeta unyoro mukati merimwe moleky chimiro. Izvi zvinodzivirira kubuda nekukurumidza kwemvura kubva kuPutty Matrix, ichiratidza kuti yakasarudzika kushanda uye kuwana hydaration yakakwana yezvisikwa zvekushandiswa. Kudzokorora kwemvura kunodzora zvakare kuderedza kuderera uye kupaza panguva yekuoma, kuvandudza kusimba uye kupedzisa pamusoro pekupedzisa.
Mechanical performance optimization
HPMC inovandudza midziyo yemakirini yezvimiro zvekutakura nekusimbisa iyo matrix uye kuvandudza kubatana. Iyo polymer inogadzira hydrogen zvisungo pamwe nezvimwe zvinoshandiswa mune putty, zvichikura simba rayo, kuchinja uye kukanganisa. Uyezve, HPMC's Film-Film Film Film Film
3.Kugadziriswa kweHPMC pane putty performance
Rheological Properties
HPMC zvakanyanya inokanganisa maitiro ekunyepedzera ezvimiro zvekutongwa, zvichikanganisa viscosity, iyo thisiotropy uye inoyerera zvivakwa. Polymer Constination, Socalular uremu uye degree rekutsiva sarudza iyo degree reViscosity kugadziridzwa, kubvumira mafomulactor kuti tailor rheological zvivakwa kune chaicho application zvinodiwa. Kugadziriswa kwakakodzera kweHPMC Dosage inovimbisa kuvaka kwakanyanya uye kushanda kwekushandisa.
Adhishing
Kuvapo kweHPMC kunowedzera kusimba kwesimba kweiyo putty kuumbwa, zvichikonzera kudzvanywa kwakavandudzwa kune akasiyana siyana ejista anosanganisira kongiri, huni, simbi uye mason. Vagadziri vanogona kugadzirisa giredhi reHPMC uye kusangana kuti uwane zvaunoda zvekubatanidza zvivakwa, kuvimba nekuwirirana nezvinhu zvakasiyana zvepasi uye mamiriro ezvinhu epamhepo. Zvakakodzera nzvimbo yekugadzirira uye nzira dzekushandisa dzinogona kuisa chisungo-kusimudzira mhedzisiro yeHPMC kuti uwedzere kusimba kusungwa uye kusimba kwenguva refu.
Vapanduki Mvura
HPMC inobatsira kuvandudza kudzikisira kwemvura kweiyo putty mafomu nekudzora kuchengetedza kwemvura uye kuderedza kubvumirana kwemvura. Iyo Polymer inoumba hydrophilic firimu iyo inhibits yemvura yekupinda mune iyo putty matrix, kudzivirira kuzvimba, kusvibiswa uye kurasikirwa kwezvinhu zvemakaniki. Kusarudzwa kwakakodzera kweHPMC mamakisi uye mafambiro ekugadzira kunogona kuenderera mberi nekuwedzera kudzikisira kwemvura, kuita kuti putty yakakodzera kune yemukati uye yekunze application inosimbiswa.
4. Simba reMuchina uye Durability
Kubatanidza HPMC muPutty mafomu anowedzera simba rekusimba, kusimba, uye kuramba kupamba, kudzikira, uye mamiriro ekunze. Iyo polymer inoshanda seyemumiriri inosimbisa, ichisimbisa putty matrix uye kuvandudza kubatana. Uyezve, kugona kweHPMC kudzora kuchengetwa kwemvura uye kusimudzira kurapwa kwakakodzera kunobatsira kuvandudza bond simba uye kuita kwenguva refu. Vagadziri vanogona kurongedza HPMC Dosage uye mafomu ekuumbwa kuti uwane iyo yakakodzera chiyero chezvimiro uye kusimba.
5. Kufunga kunoshanda kwekuumbwa
Kusarudzwa kweHPMC mamakisi
Paunenge uchisarudza yakakodzera HPMC giredhi yekuumbwa, maimba anofanirwa kufunga zvakasiyana siyana, kusanganisira viscosity, degree rekutsiva, uye kuwirirana nezvimwe zvinoshandiswa. Mapamusoro ekuvengwa emakumi maviri akakodzera kuti akwane kuti akwikwidze putties uye vertical application, nepo makomendi ekudzora zvevatenzi akakodzera kuti zviitwe zviyero zvinokatyamadza uye nyore kupararira. Vagadziri vanofanirawo kuve nechokwadi kuti kuwirirana pakati peHPMC nevamwe vanowedzera semafashama, pigment, uye vanochengetedza kudzivirira nyaya dzinoenderana uye kushomeka kwekuita.
dire optimization
Iyo huwandu hwakaringana hweHPMC zvinoenderana nezvinhu zvakadai sezvaunoda zvivakwa, nzira yekushandisa, substrate mhando uye mamiriro emamiriro ekunze. Vagadziri vanofanira kuitisa kuyedza zvakakwana kuti vazive iyo yakaderera inobudirira dhizaini iyo inowana kuita yaunoda pasina kukanganisa mutengo-kushanda. Kunyanyisa kweHPMC kunogona kuguma nekunyanyisa viscosity, matambudziko ekunyora, uye nguva dzekunyora nguva dzose, nepo underse zvinogona kuguma nekukwana renhema kudzora uye kuderedzwa kuita.
6. Kuenderana nevamwe vanowedzera
HPMC inobata nevakawanda vakawandisa vanowanzo shandiswa mune putty mafomu, yakadai seiri thizi, yakavaparadzira uye vanochengetedza. Vagadziri vanowanzoongorora zvakanyatso kuwirirana uye synergy yeHPMC pamwe nezvimwe zvinoshandiswa kuti uve nechokwadi chekuita basa uye kugadzikana. Kuongorora kuchikurukurirana, kusanganisira kuongororwa kwerudzi uye kunobatsira kwekuchengetedza kwenguva refu, kunobatsira kuona chero chinogona kutaurirana kana nyaya dzekugadzira pakutanga mukugadzirisa kuti gadziriswe uye gadziriso inogona kugadzirwa.
7. Application Technology
Maitiro ekushandisa akakodzera ekunyora anokosheswa kuti awedzere kuita kwekutongwa kwekutyisa ane hpmc. Maforama anofanirwa kupa mirayiridzo yakajeka uye nhungamiro yekugadzirira pamusoro, kusanganisa, kushandisa uye kurapa kuti uve nechokwadi chekuziva. Kuti uwane iyo inodiwa kudiwa, kusimba uye kusimba uye kusimba, maitiro akadai sekutanga, substrate mamiriro uye mitezo yakawanda-yakawandisa inogona kudiwa. Kudzidziswa uye dzidzo yevashandi vekuvaka kunowedzera kuenderera mberi, migumisiro yemhando yepamusoro, kuderedza rework uye newarle nyaya.
