Kuvandudza mhedzisiro yehydroxypropyl methylcellulose pakuchengetedza mvura kwedhaka rekuvaka

1. Kudiwa kwekuchengetwa kwemvura yehydroxypropyl methylcellulose

Kuchengetedzwa kwemvura kwedhaka zvinoreva kugona kwedhaka kuchengetedza mvura.Doka rine mvura isina kunaka rinowanzobuda ropa uye kupatsanurwa panguva yekufambisa uye kuchengetedza, kureva kuti, mvura inoyangarara pamusoro, uye jecha nesimende zvinonyura pazasi.Inofanira kumutswa zvakare isati yashandiswa.Ese marudzi emabhesi anoda dhaka rekuvaka ane kumwe kunyura kwemvura.Kana kuchengetwa kwemvura kwedhaka kwakashata, iyo yakagadzirira-yakasanganiswa dhaka ichabatwa nokukurumidza apo dhaka rakagadzirirwa rakasanganiswa rinosangana nebhokisi kana chigadziko panguva yekushandiswa kwedhaka.Panguva imwecheteyo, nzvimbo yekunze yedhaka inoputira mvura mumhepo, zvichiita kuti hunyoro husina kukwana mudhaka nekuda kwekushaya mvura, izvo zvinokanganisa kuwedzera kwe hydration ye simenti, uye panguva imwechete inokanganisa kukura kwesimba revhu. , zvichikonzera kusimba, kunyanya kuwirirana pakati pevhu rakaoma uye nheyo yepamusoro.inodzika, zvichiita kuti dhaka ritsemuka nekudonha.Kune dhaka rine mvura yakanaka yekuchengetedza, iyo simenti hydration inokwana, simba rinogona kugadzirwa zvakajairika, uye rinogona kusungirirwa zviri nani kune base layer.

2. Nzira dzekare dzekuchengetedza mvura

Mhinduro yechinyakare ndeyekudiridza hwaro, asi hazvibviri kuve nechokwadi kuti chigadziko chakanyoroveswa.Chinangwa chakanaka che hydration chesimende dhaka pachigadziko ndechekuti: simenti hydration chigadzirwa inopinda munheyo pamwe chete nekuita kwechigadziko chinotora mvura, ichigadzira "kiyi yekubatanidza" inoshanda nechigadziko, kuitira kuti uwane iyo inodiwa chisungo simba.Kudiridza zvakananga pamusoro pechigadziko kunokonzeresa kupararira kwakanyanya mumvura kunyura kwegasi nekuda kwekusiyana kwekushisa, nguva yekudiridza, uye kufanana kwekudiridza.Nheyo yacho ine mvura shoma uye icharamba ichitora mvura mudhaka.Pamberi pe simenti hydration ichienderera mberi, mvura inobatwa, iyo inokanganisa kupinda kwe simenti hydration uye hydration zvigadzirwa mumatrix;chigadziko chine mvura yakakura, uye mvura iri mudhaka inoyerera ichienda pasi.Iyo yepakati yekutama inomhanya inononoka, uye kunyange mvura-yakapfuma layer inoumbwa pakati pedhaka uye matrix, iyo inokanganisawo kusimba kwechisungo.Naizvozvo, kushandisa yakajairwa base yekudiridza nzira haizongokundikana kugadzirisa zvinobudirira dambudziko rekunyura kwemvura yakakwira yemadziro emadziro, asi kuchakanganisa kusimba kwekubatanidza pakati pedhaka nechigadziko, zvichikonzera kuputika uye kuputika.

3. Basa rehydroxypropyl methylcellulose mukuchengetedza mvura

Iko kuchengetwa kwemvura kuita kwehydroxypropyl methylcellulose kune zvakawanda zvakanaka:

(1).Kuita kwakanakisa kwekuchengetedza mvura kunoita kuti dhaka rivhurike kwenguva yakareba, uye rine zvakanakira kuvaka-nzvimbo yakakura, hupenyu hurefu hwesevhisi mudhiramu, uye kusanganisa batch uye kushandisa batch.

(2).Kuita kwakanaka kwekuchengetedza mvura kunoita kuti simende mudhaka izere hydrated, zvinobudirira kuvandudza kushanda kwechisungo chedhaka.

(3).Doka rine zvakanakisa kuchengetedza mvura kuita, izvo zvinoita kuti dhaka risanyanya kupatsanurwa uye kubuda ropa, uye inovandudza kushanda uye kuvakwa kwedhaka.
