HydroxyPropyl methylcellose (HPMC) ndeye yakakosha cellulose inoshandiswa zvakanyanya muzvivakwa zvekuvaka, kunyanya mune yakaoma-musanganiswa muguruva. HPMC isiri kungovandudza mashandiro ekuvaka emota, asiwo anovandudza zvivakwa zvemuviri uye zvemakemikari zvechigadzirwa chakapera.
Hunhu hunhu hweHPMC
HPMC isisiri-ionic mvura-yakasarudzika polymer yakagadziridzwa kubva kune yakasikwa cellulose. Zvivakwa zvayo zvinobatanidza zvinosanganisira yakanaka mvura solubility, firimu-inoumba zvivakwa, kudenha, kurerutsa uye kugadzikana. Izvi zvivakwa zvinoita kuti HPMC yakanaka kwazvo mune dzakasiyana siyana dzekushandisa, kunyanya mune motoro mafomu mune yekuvaka indasitiri.
Basa reHPMC mune yakaoma yakasanganiswa motsi
Yakawedzerwa Kuchengeta mvura
HPMC ine yakanaka mvura yekuchengetwa kwemvura uye inogona kuvandudza zvakanyanya iyo yekuchengetedza mvura yekuchengetwa kwemota. Inochekera mumvura uye inoumba solution solution, iyo inogona kuderedza kubuda kwemvura nekubuda kwemvura uye kurasikirwa, nekudaro kuchengeta mutyairi wanyorova. Iyi yekuchengetwa kwemvura yakakosha kune iyo yakazara kufambira mberi kweiyo coment hydration maitiro, ichibatsira kugadzirisa simba rekubatanidza kweiyo dhaka uye kuderedza njodzi yekupaza.
Kuita kwakasimba
HPMC yakanyungudutswa mumvura, ichaita iyo viscous collodal mvura, ichiwedzera iyo visikoka yerudzi. Iko kukonzeresa mhedzisiro kunogona kuvandudza sag kuramba durari, zvichiita kuti zvive nyore kunyorera uye kuumba dhudzi panguva yekuvaka. Izvi zvinobatsira vavaki vanoisa mongwe pane vertical nzvimbo dzakadai semadziro kudzivirira iyo mongwe kubva mukuyerera kana kudonha.
Kuvandudza Kubata
Nekuti HPMC inovandudza iyo Lubricity uye Plasuro yerukova, inoita kuti zvive nyore kusanganisa, pombi uye kupararira. Uku kuvandudzwa kunoita kuti kuvakwa kwakanakira uye kunowedzera kugona kuvaka kuvaka. Panguva imwecheteyo, inogona zvakare kuvandudza iyo thisiyo yemutya, ichigadzira muto wekutetepa kana wakatemerwa pasi peShear Dhezheni uye akakomberedzwa kana akamira, ayo anobatsira pakuvaka mabasa.
Enhence Adhishing
Iyo colloidal chimiro yakaumbwa neHPMC mumotokari inogona kusimudzira simba rekusungwa pakati pehudyu uye zvinyorwa zvibodzwa. Iyi yakashamisika kudiwa kwakakosha mukushandiswa kwakadai sedanda rekubatanidza marara kana insolation motsi kudzivirira zvinhu kubva mukutsikirira nekuderedza.
Kudzora kupaza
Sezvo HPMC inogona kuvandudza zvakanyanya kuchengetedza kwemvura yemvura, inobatsira kuderedza kuumbwa kwekutanga kuoma kuoma kutsvaira. Uye zvakare, kurongedza kwayo uye kusungwa zvinhu zvinopararira zvakare kushushikana uye kuderedza marara zvinokonzerwa nekushisa shanduko kana kuderera kweiyo substrate.
Michina yekuongorora
Molecular chimiro uye kuchengetwa kwemvura
Iyo molecular chimiro cheHPMC ine nhamba yakakura yemapoka ehydrophic, senge hydroxyl uye mapoka mapoka. Mapoka aya anoumba hydrogen zvisungo nemamolekyudhi emvura, achipa hpmc kugona kusimba kubata uye kuchengetedza mvura. HPMC yakanyungudika mumvura, vanoumba matatu-dimensional network network iyo inochengetedza mvura kuburikidza neyemuviri adsorption uye makemikari kusunga.
Colloid kugadzirwa uye kuremerwa
Mudhaka, HPMC inodonha kuumba mhinduro ye collodal. Mhinduro iyi collodal inozadza voids mudhaka uye inowedzera iyo yakazara viscosity yemutya. HPMC Mhelecular maketani anoumba chimiro chakasimba network kuburikidza nekubatanidza uye kushamwaridzana kwepanyama, ipapo nekuwedzera kuwedzera viscosity yerudzi.
Lubrication uye kushanda
HPMC Mhezi yemanyorerwo anoita sechiuno mudhaka. Ivo vanogona kuumba firimu remanyorerwo pamusoro pechikamu cheggregate, vachideredza kupokana pakati pezvikamu. Iyi mhedzisiro yemhedzisiro inoita kuti dorari ive nyore kumutsa uye kuvaka, kuvandudza kusimba kwekuvaka.
InterFacious Adernon uye Cohemon
Iyo colloidal chimiro cheHPMC ichaumba firimu rakatetepa mushure mekuoma. Iyi firimu yakatetepa inokwanisa kuomerera kune iyo nzvimbo yeiyo yetsiva uye inosimudzira simba rekubatanidza pakati peiyo dhaka uye zviyero zvebhokisi. Izvi zvinokoshesa zvakakosha pakuvandudza iyo yakanamatira zvinhu zvevhu.
Rinoshandisa mienzaniso yeHPMC
Tile boging merare
MuCeramic Tile Kubatanidza Moriri, Kuchengetwa kwemvura uye kusungirwa kweHPMC kunoona kuti dhiza rine nguva yakakwana nguva yekubatanidza kana ichivhara mataira ekurongedza, kudzivisa mataira ekurongedza kubva pakudonha nekutsvedza panguva yekuomesa.
Kupururudza moterring
MuClastering Mortars, iyo yakakora mhedzisiro yeHPMC inoita kuti zvive nyore kushandisa mhodzi kumadziro uye kudzivirira dhaka kubva mukudonha. Yayo yakanaka mvura yekuchengetedza midziyo zvakare inoderedza njodzi yekupaza mune plaster layer.
Kuzvimanikidza mucheche
Zvekuzvifunga wega, iyo thiskricarropy uye inokweretesa yeHPMC inoona kuti mongwe ine mongororo yekuzvimiririra kana ichinge yayerera, nepo yakakodzera viscosity painomira, iyo yakakodzera mabasa ekuvaka.
Basa reHPMC mune yakaoma-yakavhenganiswa dhaka inowedzera. Izvo hazvingovandudze mashandiro emununuri nekuvandudza kudzokorora kwemvura uye kuzvidzora, asi zvakare kunowedzera maitiro ekuvaka nekuvandudza kushanda uye kuderedza. Kushandiswa kweHPMC kwakaita kuti musanganiswa wakaoma-musanganiswa uchishandiswa zvakanyanya mukuvakwa kwemazuva ano, kuvandudza kwazvo mhando uye kushanda kwekuvaka. Mune ramangwana, nekuenderera mberi kwekufambira mberi kwekuvaka tekinoroji, iyo application chiyero uye mhedzisiro yeHPMC ichawedzera kuwedzera uye yakawedzerwa.
