Hemc (HydroxyTHETL MetHyl Cellelose) Icho Chinyorwa-Chemvura Polymer Polymer inoshandiswa mukuvaka. Iyo inonyanya kuita basa mukuvandudza iyo fluidity yeiyo coment paste uye kunonoka coment hydration maitiro. Mune hydration process yeiyo coment, hemc ine imwe pesvedzero pane hydration maitiro uye kuita kwesimendi.
1. Zvekutanga zvivakwa zve hemc
Hemc is polymer yakaumbwa nemakemikari kugadziridzwa kwemasikirwo cellulose. Yayo molecular chimiro ine maviri subsituets, hydroxylyl uye methyl, iyo inoita kuti ive yakanaka solubility, viscosity yekugadzirisa kugona uye mafirimu ekugadzira mafirimu. Sezvinobvumwa sechiitiko chekenzesa, hemc inogona kuvandudza fluidity yayo, kushanda kwekuvaka, uye kupindira mumasimendi pasita, uye kunogona kuvandudza simba uye kusimba mushure mekuomesa musoro.
2. Mhedzisiro yeHemc paComent Hydration Process
Simende hydration ndiyo nzira yeiyo simende uye maitiro emvura. Kuburikidza nekuita uku, cement pasita zvishoma nezvishoma inoomesa kuumba sosi yakasimba matrix. Sechikumbiro, hemc inogona kutamba akasiyana siyana emigodhi muhyori hydration. Mhedzisiro chaiyo ndeyekutevera:
2.1 Kuvandudza iyo Fluidity yeStument Slurry
Muchikamu chekutanga cheiyo simende hydration, iyo fliliity ye simende slurry haina kunaka, iyo inogona kukanganiswa panguva yekuvaka. Hemc inogona kubatsira zvinobudirira kuyamadza kweiyo simende slurry nekuda kweiyo yepamusoro vhiza uye yakanaka mvura yekurudyi. Inopararira zvidimbu zveSement uye inoderedza kusunganidzwa pakati pekusimbisa zvidimbu zvidimbu, nekukasira kuvandudza kuenderana kwesimende slurry, zvichiita kuti zvive nyore kushanda uye kudururira panguva yekuvaka.
2.2 kunonoka kweiyo hydration maitiro
Iyo hydroxytHyl boka muHemc ine yakasimba hydrofiromity. Inogona kuumba iyo hydration firimu pamusoro pechikamu chechisimba, kudzikisira kumhanya kwekusimudzira pakati pechidimbu uye mvura, nekudaro kunonoka nzira yehystem yeiyo siment. Uku kunonoka mhedzisiro kwakakosha zvakanyanya mukudziya kwakanyanya kana kukurumidza kuvaka. Inogona kudzivirira kusava nesimba kusingaperi kwesimba kunokonzerwa nekunyanyisa hyderration ye simende, uye inogona kuwedzera nguva yekuvaka kudzivirira matambudziko ekuoma ekuoma.
2.3 Kuvandudza kugadzikana kweiyo simbe slurry
Munguva yeiyo hydration process yemasimende slurry, hemc inogona kubatsira zvinobudirira kugadzikana kweiyo slurry. Iyo hydroxyethyl uye methyl mapoka mune hemc molecule inogona kupindirana neiyo simenti zvidimbu kuburikidza neHydrogen zvisungo uye van der waals masimba kuti aumbe chimiro chakagadzikana. Kugadzikana uku kunobatsira kudzivirira kufungidzirwa muComent Paste, nokudaro kuvandudza kufanana kweiyo cement pasita uye kuona kugadzikana kweiyo siment hydration maitiro.
2.4 Kuvandudza iyo microgramu yeiyo coment hydration zvigadzirwa
Hemc inogona kuvandudza microgramu yeiyo coment hydration zvigadzirwa nekugadzirisa iyo fluidity newiscosity yeiyo cement paste. Semuenzaniso, mune imwe nhanho yeiyo simende hydration, hemc inogona kukanganisa kuumbwa uye kugovera kweiyo hydration zvigadzirwa mumasimendi paste, senge hydated calcium (csh) gel. Munguva yeiyo yeiyo hydration maitiro, kuumbwa kweCHS GE chikamu chakakosha mukusarudza simba uye kusimba kwesimbisi. Hemc inogona kusimudzira kugovera yunifomu yeCSS gel uye kugadzirisa iyo density uye kusimba kwesimbe nekugadzirisa iyo ION yekuisa muComent hydration maitiro.
2,5 Mhedzisiro paSeent Simba
Mhedzisiro yeHemc pane SIMEMEN SIMBA RINOGONESESWA NECHEMA CHEMA CHEMA Muchikamu chekutanga cheiyo coment hydration, kusimba kwekutanga kwesimende kunogona kuderedza zvishoma nekuda kwekudzosera mari yehemc. Nekudaro, sekusimbisa kweiyo hydration inoenderera, hemc inogona kubatsira kugadzira denser coment chimiro, nekudaro uchivandudza simba rekupedzisira remari panguva yekurapa kwenguva refu. Mukuwedzera, hemc inogona kuvandudza kupaza kupokana kwesimendi, kusimudzira kusakwana kweiyo simende chimiro, uye kugadzirisa kusimba kwesimendi.
3. Zvimwe zvinokonzeresa hemc pa coment
Pamusoro pemigumisiro iri pamusoro apa paComent hydration process, hemc zvakare ine zvimwe mhedzisiro pane zvimwe zvinhu zvezvivakwa, kunyanya kusanganisira:
3.1 Kuvandudza iyo Frost Ristance uye kusakwana kweiyo simende
Hemc inogona kuvandudza microcenture yeiyo simende, kuitira kuti igone kuburitsa denser cement matrix panguva yehydration maitiro. Iyi dense dhiza inogona kudzikisa zvinobudirira porosimba mukati meiyo simende, nekudaro ichivandudza iyo yechando kuramba uye kusakwana kwesimendi. Mumamiriro ezvinhu akawandisa, kupokana kwechando uye kusakwana kweiyo coment mamiriro akakosha pakugadzikana kwenguva refu kwezvivakwa.
3.2 Simbisa iyo Corrosion Kudzivisa SEMENT
Sezvo hemc inovandudza kushambadzira kweiyo coment paste, inogona zvakare kudzora kuvapo kwemapres mukati mechero, kuderedza kupinzwa kwemvura, gasi kana makemikari, uye nokudaro anovandudza basa rokubata. Kunyanya mune dzimwe dzakanyorovesa kana acid-base nharaunda, hemc inogona kubatsira kuwedzera hupenyu hwebasa rezvimiro zve coment.
4. Mari yacho uye mhedzisiro yeHemc
Mhedzisiro yehuwandu hwe hemc pane yeiyo yeiyo hydration maitiro chikamu chakakosha. Kazhinji, huwandu hwehupfu hunowedzerwa hunofanirwa kugadziriswa zvinoenderana nezvinodiwa chaizvo. Yakawandisa hemc inogona kukonzera simende slurry kuve nekukwira kwakanyanya uye kukanganisa maitiro ekuvaka; Nepo kusakwana kwekuwedzera kunogona kusatamba zvizere basa rayo mukuvandudza kuita kwesimendi. Kazhinji, huwandu hwaHemc yakawedzerwa kuSumbiro
Sezvinoratidzwa nesimende, hemc inoita basa rakakosha mukuvandudza iyo simbe simbe slurry, ichinonoka hydration maitiro, uye kuvandudza microcenture uye kusimba kwesimbe. Kushandisa zvine musoro kwehemc kunogona kuvandudza kuita kwesimendi kune imwe nhanho, kunyanya mukuvandudza kushanda kwesimendi, nekuwedzera nguva yekudyara, uye kusimudzira simba uye kusimba kwesimendi yakaomeswa. Nekudaro, iyo huwandu hwe hemc yakashandiswa inoda kugadziridzwa zvinoenderana nemamiriro chaiwo kuti uve nechokwadi chekuita kwayo. Mumapurojekiti ekuvaka, kushandiswa kweHemc kuchabatsira kuvandudza kunaka uye kusimba kwezvigadzirwa zve siment.
