Hydroxypropyl methylcellulose (HPMC) inoshandiswa zvakanyanya muindasitiri yekuvaka, kunyanya mune simende-yakavakirwa zvinhu.Hunhu hwayo hwakasiyana hunoita kuti ive chikamu chakakosha mune zvakasiyana-siyana zvekushandisa, kubva pakuvandudza kushanda kusvika pakusimudzira kushanda uye kusimba kwekongiri nemadhaka.
1. Tsanangudzo uye mhedziso yehydroxypropyl methylcellulose
Hydroxypropyl methylcellulose, inowanzopfupikiswa seHPMC, iri cellulose-based polymer inotorwa kubva muhuni pulp kana donje.Iyo yakawanda-inoshanda yekuwedzera ine yakasarudzika rheology, adhesion uye mvura yekuchengetedza zvivakwa.Kana yawedzerwa kune simende-yakavakirwa zvinhu, HPMC inoita seyakawanda inoshanda mumiriri, inokanganisa hutsva uye hwakaomeswa zvimiro zvemusanganiswa.
2. Zvitsva zvitsva zvesimenti-based materials: kushanda uye rheology
Rimwe remabasa makuru eHPMC mune simende-yakavakirwa zvinhu kuvandudza kushanda.Kuwedzerwa kweHPMC kunovandudza rheological properties yemusanganiswa, zvichiita kuti zvive nani kuyerera uye nyore kuisa.Izvi zvinonyanya kukosha mumashandisirwo akadai sekuiswa kwekongiri uye zvikumbiro zvedhaka, uko kushanda kuri chinhu chakakosha.
3. Kuchengeta mvura
HPMC inoshanda sechinhu chinochengetedza mvura, ichidzivirira kurasikirwa kwemvura yakawandisa kubva kune simende zvinhu panguva yekutanga kurapa.Uku kuchengetwa kwemvura kwakagadziridzwa kunobatsira kuchengetedza yakakwana hydration mamiriro emasimende masimende, kukurudzira kukura kwesimba uye kusimba.
4. Kuomesa zvinhu, simba uye kusimba kwesimenti-based materials
Kufurira kweHPMC pane kuomesa zvinhu zvesimende-yakavakirwa zvinhu kwakakosha.HPMC inobatsira kuwedzera simba rekumanikidza rekongiri nekuvandudza kushanda uye kuchengetwa kwemvura munzvimbo nyowani.Pamusoro pezvo, iyo yakagadziridzwa hydration process inokonzeresa denser microstructure, iyo inowedzera kusimba kwechinyorwa uye kuramba kune zvakatipoteredza zvinhu zvakaita sechando-thaw kutenderera uye kurwisa kwemakemikari.
5. Deredza kupera
Cement-based materials inowanzo derera panguva yekurapa, zvichiita kuti pave nekutsemuka.HPMC inoderedza dambudziko iri nekudzikisa zvinodiwa mvura yemusanganiswa, nekudaro ichideredza mukana wekuputsika kwe shrinkage.Iyo inodzorwa yemvura yemukati inosimudzirwa neHPMC inobatsira kuchengetedza dimensional kugadzikana kwezvinhu zvakaomeswa.
6. Kunamatira uye kunamatira zvinhu
HPMC inobatsira kuvandudza zvivakwa zvinosungirirwa zvesimende-zvakavakirwa zvinhu uye inovandudza kunamatira pakati pezvinhu uye akasiyana substrates.Izvi zvinonyanya kukosha mumashandisirwo akadai sematairi adhesives uye plasters, apo zvisungo zvakasimba zvakakosha kune hupenyu hurefu uye kushanda kwechivako.
7. Kuvandudza kubatana
Pamusoro pekusimudzira kunamatira, HPMC inogona zvakare kuvandudza kubatanidzwa kwezvinhu pachayo.Izvi zvinobatsira apo simende-yakavakirwa zvinhu zvinoda kunamatira kune yakatwasuka kana kuchengetedza chimiro chazvo panguva yekushandisa.
8. Matambudziko uye Mafungiro Dosage uye Kuenderana
Nepo HPMC ine akawanda mabhenefiti, kushanda kwayo kunoenderana nedosi chaiyo.Kushandisa zvakanyanya kana kushandiswa zvisina kunaka kweHPMC kunogona kukonzera mhedzisiro yakadai sekunonoka kuseta nguva kana kuderedzwa kwesimba.Pamusoro pezvo, kuenderana nezvimwe zvekuwedzera uye zvinosanganiswa zvinofanirwa kutariswa kuti ive nechokwadi chekuita kwakanyanya mune chaiyo application.
9. Kukanganisa kwezvakatipoteredza
Iko kukanganisa kwezvakatipoteredza kwekushandisa HPMC mune zvekuvaka idambudziko riri kukura.Nepo HPMC pachayo ichiora, kusimba kwese kwekugadzirwa kwayo uye kushandiswa kunoda kutariswa.Vatsvagiri nenyanzvi dzemaindasitiri vari kutsvaga zvimwe zvinowedzera zvine hushamwari kwezvakatipoteredza zvinogona kupa mabhenefiti akafanana pasina kukanganisa kwezvakatipoteredza.
mukupedzisa
Muchidimbu, hydroxypropyl methylcellulose inoita basa rakakosha mukuvandudza mashandiro esimende-yakavakirwa zvinhu.Kubva pakuvandudza kushanda uye kuchengetwa kwemvura munzvimbo nyowani kusvika pakuwedzera simba, kusimba uye kunamatira munzvimbo yakaoma, HPMC inobatsira kuvandudza huwandu hwese hwezvinhu zvekuvaka.Nekudaro, kuti uone kugona kwakazara kweHPMC uku uchisimbisa maitiro ekuvaka akasimba, dosi, kuenderana uye kukanganisa kwezvakatipoteredza kunofanirwa kutariswa.Sezvo indasitiri yekuvaka ichienderera mberi nekushanduka, kuenderera mberi nekutsvagisa uye kusimudzira kunogona kutungamira kune humwe hutsva mumatekinoroji ekuwedzera, zvichipa mhinduro dzakavandudzwa kumatambudziko akatarisana nekuvaka kwazvino.
