Izixazululo ezivamile zokwakha phansi kwezimoto ezingaphansi komhlaba

Ezindaweni zokupaka izimoto ezingaphansi komhlaba, izixazululo ezivamile zaphansi zifaka: phansi okune-epoxy, phansi okugugayo kanye naphansi okungena okuqinile.

Uphahla lwe-Epoxy: uphahla lwe-epoxy egaraji

Uphahla lwe-epoxy, okungukuthi, upende wephansi we-epoxy resin njengento eyinhloko, ngesihlabathi/impuphu ye-quartz njengezinto ezisizayo, kusetshenziswa ukugaya, ukuhlanza nge-vacuum, ukuklwebha, ukugoqa noma ukufutha nezinye izindlela zokwakha, ukuze kutholakale indawo ephansi. Ngemva kokwakhiwa komhlabathi, ungqimba lwe-epoxy lumboza ukhonkolo wesamente wezimpande zotshani, ngaleyo ndlela luhlukanise ngokuyisisekelo ukhonkolo wezimpande zotshani ezinkingeni ezingaba khona njengesihlabathi, uthuli nokunye. Indawo ephansi ye-epoxy, ayinazo uthuli, ayigugi, kulula ukuyihlanza, inombala ogqamile.

Izixazululo ezivame ukusetshenziswa njenge-epoxy flooring flooring flooring yilezi: i-motar type epoxy flooring, i-thin coating type epoxy flooring, i-self-leveling type epoxy flooring.

Uphahla lwe-epoxy olufana nodaka, inqubo ngokuvamile iwukuba: ukugaya nokuhlanza i-substrate, i-epoxy primer eyodwa, i-epoxy mortar eyodwa noma ezimbili, i-epoxy putty ezimbili, i-epoxy surface coating ezimbili. Ubukhulu buphakathi kuka-0.8-1.5mm.

Uphahla lwe-epoxy oluncane olune-coating encane, inqubo ngokuvamile iwukugaya nokuhlanza i-substrate, i-epoxy primer eyodwa, i-epoxy mortar eyodwa, i-epoxy putty eyodwa, i-epoxy surface coating eyodwa. Ubukhulu buphakathi kuka-0.5-0.8mm.

Uphansi lwe-epoxy oluzilinganisayo, inqubo ngokuvamile iwuku: ukugaya nokuhlanza i-substrate, i-epoxy primer eyodwa, i-epoxy mortar ezimbili, i-epoxy putty eyodwa, i-epoxy flow plane coating eyodwa. Ubukhulu buphakathi kuka-2-3mm.

Uphahla oluncane lwe-epoxy olufana nolwe-coating, olusekelweni lomhlabathi kuphela oluyisicaba kakhulu, amandla ekhonkrithi mahle kakhulu, futhi isabelomali sezindleko silinganiselwe kakhulu, umphumela obonakalayo wezidingo zekesi awuphezulu, ngokuvamile awunconywa. Uphahla oluncane lwe-epoxy olufana nolwe-coating, uma luqhathaniswa nophahla oluncane lwe-epoxy olufana nolwe-coating, ubuso buyisicaba kakhulu, buthambile, bumelana nokuguguleka, ukumelana nomthelela kunamandla, uhlelo lophahla olungaphansi komhlaba lwe-epoxy. Uphahla oluzilinganisayo lwe-epoxy lusetshenziswa kuphela ezinhlanganweni zikahulumeni, ezindaweni zama-Olympic nakwamanye amaphrojekthi kazwelonke ezindawo zokupaka izimoto ezingaphansi komhlaba. Ngaphezu kwalokho, amaphrojekthi ngamanye, uma umsebenzisi engalandeli uphahla oluphezulu kanye nemiphumela yokuzwa, ukuze nje axazulule ubuso bekhonkrithi besihlabathi, uthuli, kunezinhlobo ezimbili ze-epoxy primer, uphahla oluphezulu lwe-epoxy olufana nohlelo olulula lwe-epoxy.

Ngakho-ke, isici esibalulekile sokukhetha ukuthi yiluphi uhlobo lohlelo lwephansi lwe-epoxy, okokuqala, isisekelo somhlabathi, okwesibili, ukuthi hlobo luni lomphumela oludingekayo ukuze kufezwe, bese kuba isabelomali sezindleko. Phakathi kwalokhu okuthathu kucacile, kuyahambisana.

Iphansi elingagugi

Izinto zokwakha phansi ezingagugi ezisekelwe kusimende, ezakhiwe ngesimende esikhethekile, i-aggregate engagugi (isihlabathi se-quartz, i-emery, i-tin-titanium alloy, njll.) kanye nezithasiselo nezinye izingxenye, ukuze kulinganiswe ngokwesayensi kusetshenziswa indlela exutshwe kusengaphambili yefektri yokukhiqiza i-powder esikhwameni.

Ukwakhiwa kwephansi elingagugi kuhambisana nokwakhiwa kwekhonkrithi yesamente. Ngemva kokugandaya okuvamile, ukulinganisa kanye nokudlidliza kwekhonkrithi yesamente ebusweni bepaki yokupaka engaphansi komhlaba, izinto zephansi ezingagugi zizosakazwa ebusweni esigabeni sokuqala sokuqina, kanti izinto ezingagugi zizokwakhiwa zizonke ngekhonkrithi yesamente ngethuluzi elikhethekile lokwakha phansi, umshini wokushelela, ukuze kwakheke ungqimba oluvikelayo engqimbeni engaphezulu yekhonkrithi yesamente.

Njengoba sonke sazi, iningi lekhonkrithi elijwayelekile lendawo yokupaka izimoto ngaphansi komhlaba i-C20, i-C25 ejwayelekile, i-C25, isibonelo, amandla okucindezela ebusweni angaba ngu-25MPA. Kodwa ngemva kokwakhiwa kwephansi elingagugi, amandla okucindezela ebusweni angafinyelela ku-80MPA, noma ngisho nangaphezu kuka-100MPA, kanti amanye amandla okuguquguquka, amandla angagugi kanye nezinye izinkomba nazo zithuthukisiwe kakhulu.

Ngoba iphansi elingagugi lingokwemikhiqizo esekelwe kusimende, ngakho-ke lingahlanganiswa kahle nekhonkrithi yesamente, inqobo nje uma i-concrete yezimpande zotshani ingaphukile, iphansi elingagugi amashumi eminyaka ngaphandle kokuphuka, ngaphandle kokuwa. Ngesikhathi esifanayo, umbala awumuhle futhi awucebile njengophansi we-epoxy, ngokuvamile ompunga, oluhlaza okotshani, obomvu neminye imibala eyisisekelo.

Ikhonkrithi evamile yesamente, ngenxa yokukhiqizwa okungafanele kanye nokwakhiwa, noma ukuwohloka kweminyaka eminingi, kulula ukuyiphendula isihlabathi, uthuli, okungukuthi, ikhonkrithi yesamente ekuhlukaniseni isihlabathi, itshe kanye nesamente. Lolu hlobo lwendawo yokupaka izimoto engaphansi komhlaba, ukuhlanza imvelo kuyakhathaza kakhulu, ubuso bezimoto ezipakiwe bumbozwe uthuli, umnikazi ukhononda kakhulu. Iphansi elingagugi liyisisombululo esingabizi futhi esisebenzayo sale nkinga. Inhlabathi ayisabonakali isenzakalo sesihlabathi nothuli, futhi ngokugaya nokungqubuzana kwemoto, umhlabathi ongagugi uzofinyelela ezingeni elithile lokukhanya.

Iphansi elijwayelekile elingaphansi komhlaba elingagugi, elinohlobo lwesihlabathi se-quartz kanye nephansi elinohlobo lwedayimane elingagugi. Umbala uvame ukuba nombala wesamente noma ompunga.

phansi okungena ngokuqina

Iphansi legaraji elingene ngqo phansi kwekhonkrithi, phansi elingenesihlabathi, phansi kwe-terrazzo, njll., uma igaraji lithelwe ukhonkrithi futhi lahlelwa phansi, kunconywa ukwenza ngqo phansi kwe-Yade's penetrant, ukwakhiwa kulula, izinkomba zobuchwepheshe kanye nephansi elingenesigugi lifana nokugcinwa kamuva kulula kakhulu, okubuye kube yinzuzo yephansi legaraji elingenesigugi. Iphansi le-Yade lapho inhloso yokuqala yokuthuthukiswa kwephansi elingenesigugi, ukuthola indawo yephansi le-epoxy, kodwa futhi nezinzuzo eziqinile zephansi elingenesigugi, phansi elingenesigugi ngemuva kokwakhiwa kombala akufiki phansi kwe-epoxy njengoba kunemibala, kodwa umehluko awumkhulu, umehluko phakathi kwalokhu okubili ulele ekujiyeni kwephansi le-epoxy ukujiya okuthile, uma ukwakhiwa okubi sekwakhiwe, kulula kakhulu ukususa isimo sesikhumba, futhi ukulungiswa nokugcinwa kwesikhashana kuyakhathaza kakhulu, futhi indima yendlela yokusebenza kwephansi le-Yade. Indlela yokubeka phansi engenela phansi iwukungena phansi kwekhonkrithi, futhi isabela ngokhonkrithi, futhi ekugcineni yenze ubuso bube yinto evaliwe, hhayi nje kuphela ukuxazulula ukusantiwa kokhonkrithi kanye nomcimbi ompunga ngesikhathi esifanayo kungandisa kakhulu ubulukhuni bomphezulu wekhonkrithi, futhi ngesikhathi esifanayo isixazululo se-asidi ne-alkali sidlala indima ethile ngokuhlukaniswa, abanikazi bezindlu abaningi emakethe basebenzisa phansi engenela phansi njengesisekelo sokuqala segaraji.
