Chii chinonzi bentonite jira remvura rakagadzirwa ne:
Rega nditange kutaura nezve bentonite.Bentonite inonzi montmorillonite.Zvinoenderana nechimiro chayo chemakemikari, yakakamurwa kuita calcium-yakavakirwa uye sodium-yakavakirwa.Chimiro chebentonite ndechekuti inoputika nemvura.Apo calcium-based bentonite inoputika nemvura, inogona kusvika kune yayo pachayo.Sodium bentonite inogona kutora kashanu uremu hwayo painoputika nemvura, uye kuwedzera kwehuwandu hwayo kunosvika kupfuura 20-28 nguva yehuwandu hwayo.Nekuda kwekuti iyo yekuwedzera coefficient ye sodium bentonite isina mvura gumbeze yakakwirira, ikozvino inoshandiswa kakawanda..Sodium bentonite yakavharwa pakati pezvikamu zviviri zve geosynthetics (pazasi pakarukwa geotextile, uye kumusoro ipfupi-filament geotextile), iyo inoita basa rekudzivirira nekusimbisa.Iyo gumbeze zvinhu zvakagadzirwa neasina kurukwa tsono kubaya kunoita kuti GCL ive nehumwe simba rekugera.
Zvakanakira bentonite isina mvura gumbeze:
1: Compactness: Mushure mokunge sodium bentonite inoputika mumvura, ichaita membrane yepamusoro-soro pasi pekumanikidzwa kwemvura, iyo yakaenzana ne100 nguva yekubatana kwe30cm ivhu gobvu, uye ine simba rekuchengetedza mvura.
2: Mvura isina mvura: Sezvo bentonite inotorwa kubva kune zvakasikwa uye inoshandiswa mumasikirwo, haizove ichichembera kana yakasvibiswa mushure menguva yakareba kana kuti nzvimbo yakapoteredza inoshanduka, saka kushanda kwemvura kunogara kwenguva refu.Asi haigone kushandiswa mu-high-concentration electrolyte solution yekudzivirira mvura uye anti-seepage mapurojekiti.
3: Kuvimbika: kubatanidzwa kwebentonite jira remvura uye nzvimbo yepasi.Mushure mokunge sodium bentonite inoputika nemvura, inoumba muviri wakagadzikana nemamiriro epasi, inogona kuenderana nekugadzirisa kusina kuenzana, uye inogona kugadzirisa kuputika kwemukati mukati me2mm.
4: Green uye kuchengetedzwa kwezvakatipoteredza: Sezvo bentonite inotorwa kubva kune zvakasikwa, haizokanganisa zvakatipoteredza uye vanhu.
5: Kukanganisa kwenzvimbo yekuvaka: Haina kukanganiswa nemhepo ine simba uye kutonhora kwemamiriro ekunze.Zvisinei, nekuda kwekuzvimba kwebentonite kunosangana nemvura, kuvaka hakugone kuitwa pamazuva ekunaya.
6: Kuvakwa kwakapusa: Kuenzaniswa nezvimwe zvinhu zvegeotechnical, gumbeze rebentonite risingapinde mvura riri nyore kugadzira uye haridi welding.Iwe unongoda kusasa bentonite poda pane inopindirana uye gadzirisa nezvipikiri.
Chinangwa chebentonite isina mvura gumbeze:
Inonyanya kushandiswa mumadhamu ekugadzira, nzvimbo dzemvura, nzvimbo dzekurasira pasi, magaraji epasi pevhu, kuvaka zvivakwa zvepasi pevhu, magadheni edenga, madziva, madhiri emafuta, mayadhi ekuchengetera makemikari uye mamwe mapurojekiti ekugadzirisa kuvhara, kuzviparadzanisa nevamwe, uye anti-leakage matambudziko, uye kuramba kwakasimba kuparadzwa. mhedzisiro yakanaka.
