1. Yibuphi ubukhulu obungasetshenziswa yi-self-leveling cement? Uyini umehluko phakathi kwe-underlayer kanye ne-top-leveling cement?
Usimende ozimele ongaphansi kwesendlalelo uvame ukufakwa ku-2–10 mm. Usetshenziswa kakhulu ekulinganiseni phansi, kufakwe phansi, i-PVC noma ikhaphethi phezulu. Usimende ozimele ongaphezulu ungasetshenziswa ku-2–5 mm. Wakha indawo ebushelelezi eqediwe futhi ungasebenza njengokuphela kwephansi lokugcina. Ukuze ubukhulu budlule umkhawulo ophezulu, kunconywa ukufaka amajazi amaningi ukuvimbela ukuqhekeka.
2. Isembozo Esinamathelayo Sethayela Ngesikhwama: 20 kg?
Uma isetshenziswa ngobukhulu obungu-10 mm, ukusetshenziswa kwe-SDH YS-202 underlayer self-leveling cement cishe kungama-17 kg ngemitha yesikwele. I-primer efanayo inesilinganiso sokumboza esingaba ngu-5–8 m² ngelitha. Ukusetshenziswa kwangempela kuncike ekubuneni kokusetshenziswa kanye nesimo sangempela se-substrate.
3. Yiziphi izici ezibangela ukuthi ukumbozwa kwangempela kungabi sezingeni elifanele leshidi lemininingwane?
Ukumbozwa kwangempela akulingani nesibalo esishicilelwe ikakhulukazi ngenxa yezici ezine ezihlanganisayo: ukugoba kwe-substrate, ukuguguleka kwe-trowel, ukunamathela ngaphambi kokubekwa kwethayela, kanye nezidingo zokufaka ibhotela emuva kwamathayela amakhulu. Isiqondiso se-British Standards sixwayisa ukuthi ukusetshenziswa kwangempela kufinyelela ku-15-25% ngaphezu kwamanani e-TDS enkolelo.
4. Yini ebangela ukuthungwa kothuli ebusweni futhi ingavinjelwa kanjani?
Uthuli olungaphezulu kodaka oluzilinganisayo luvame ukubangelwa amanzi amaningi axubile akhuphula isilinganiso samanzi nosimende engqimbeni yobuso, ukungagayeki kahle okuvimba ukumuncwa kwamanzi kusenesikhathi, noma i-substrate engakavuthwanga idonsa umswakama kusuka phezulu okusha.
5. Ngingazi kanjani ukuthi ukuthulula uthuli phansi kwami okwelula kuyiphutha lokwakheka noma iphutha lokuxuba nokusebenzisa?
Ukuthululwa kothuli olungaphezulu okubangelwa yiphutha lokwakheka kuvame ukuvela njalo kuzo zonke izinhlobo futhi kungakhathalekile inqubo yomfaki, kuyilapho ukuthululwa kothuli okubangelwa ukusetshenziswa kuvame ukuhlotshaniswa nokuthululwa okuthile, ukwengeza amanzi, isimo se-substrate, noma indawo yokupholisa - futhi izinto ezijulile zivame ukuhlola umsindo.
6. Ingabe ukusebenzisa i-consolidating primer kungalungisa indawo enothuli ekwazi ukuzilinganisela, noma ingabe kudingeka ngigaye bese ngiphinde ngiyithulule?
I-densifier esekelwe ku-silicate noma i-primer ehlanganisayo ingabopha unomphela izinhlayiya ezikhululekile futhi igcwalise ama-porosity ebusweni phansi othulini oluncane lapho izinto zomsindo zingaphakathi kwe-1-2 mm ebusweni.
7. Yimuphi idatha yokuvumelana kweqoqo kanye nemiphumela yokuhlolwa kwelebhu okufanele ngiyicele kumhlinzeki wami ukuqinisekisa ukuthi ifomula yabo imelana nokuthululwa kothuli ebusweni?
Ukuqinisekisa ukuthi ifomula yodaka oluzilinganisayo imelana nokuthululwa kothuli olungaphezulu, cela isitifiketi se-QC sebhetshi yokukhiqiza esibonisa isidingo samanzi, ukusabalala kwetafula lokugeleza, kanye namandla okucindezela amahora angama-24 ngesikhathi ngasinye sokugijima.
8. Ingabe usimende wakho ozimele usekelwe ohlelweni lwesimende lwe-sulfoaluminate noma olujwayelekile lwe-Portland?
Sinezinhlelo zombili ozikhethayo. I-Sulfoaluminate self-leveling inamandla asheshayo okuqala kanye nokuncipha okuphansi, ilungele amashejuli okwakha aqinile. Uhlobo olujwayelekile lwesimende sasePortland lunikeza ukusebenza okungcono kwezindleko kanye nokusebenza okuzinzile, okusetshenziselwa kakhulu amaphrojekthi okulengisa phansi angaphakathi.
9. Ingabe ingasetshenziswa ngaphandle?
Usimende ojwayelekile wokuzilinganisa unconywa ukuthi usetshenziswe ngaphakathi endlini kuphela. Uhlobo olujwayelekile alukwazi ukumelana nokuchayeka emvuleni isikhathi eside noma imijikelezo yokuncibilika nokubanda. Uma kudingeka ukusetshenziswa ngaphandle, sicela ukhethe udaka lwethu olushintshiwe oluzilinganisayo lwangaphandle.
10. Ingabe ukwakhiwa kungenziwa phansi okumanzi? Iyini imfuneko yokuqukethwe komswakama?
Umswakama we-substrate kufanele ube ngaphansi kuka-8%. I-primer engangenisi umswakama kumele ifakwe ngaphambi kokufakwa phansi okumanzi. Ukusetshenziswa ngqo kwi-substrate enomswakama omningi kuzobangela ukuqhakaza, ukuqhekeka kanye nama-bubble omoya, okunciphisa kakhulu amandla okubopha.
11. Kufanele kufakwe amanzi angakanani ngesikhwama/ngebhakede? Kwenzekani uma kufakwe amanzi amaningi noma amancane kakhulu?
Hlanganisa ngokuqinile ngokulandela isilinganiso somkhiqizo (ngokuvamile impuphu: amanzi ≈100:22~26, kuyahlukahluka kuye ngemodeli). Amanzi amaningi azoholela ekuncipheni kwamandla, ukusantiwa, ukushwabana kanye nokuqhekeka. Amanzi anganele abangela ukugeleza okungekuhle; inhlanganisela ayikwazi ukuzilinganisa futhi ishiye indawo engalingani.
12. Kungavunyelwa isikhathi esingakanani ukuhamba ngezinyawo ngemva kokuthulula? Iphansi/i-PVC ingafakwa nini?
Ngaphansi kwezinga lokushisa elijwayelekile kanye nomswakama (20℃): ukuhamba ngezinyawo okulula kuvunyelwe ngemva kwamahora angaba ngu-4-6; phansi okugobekayo kungabekwa ngemva kwamahora angu-24. Ukuqina okugcwele kuthatha izinsuku ezingu-7 ukuze kufinyelele emandleni okugcina. Isikhathi sidinga ukwelulwa ngaphansi kwezimo zokushisa eziphansi.
13. Ungabhekana kanjani nemifantu engaphansi komhlabathi? Ingabe ukuzilinganisa kuzoqhekeka kanye nesisekelo?
Imifantu ebanzi kuno-0.3mm idinga ukusika nokulungiswa kanye netheyiphu ye-fiberglass mesh. Imifantu emincane yezinwele kufanele ivalwe nge-primer. Ukuzilinganisa kungamboza futhi kusheleleze indawo, kodwa akunakuvimba i-substrate ukuthi ingaqhekeki kakhulu. Imifantu eqhubekayo esisekelweni izobonakala nge-topping yokuzilinganisa.
14. Ingabe ingashintshwa umbala?
Ukuzilinganisa okujwayelekile kumpunga. Izinga eliphezulu lingafakwa umbala ngemibala ekhethekile engaphili. Ngemibala emnyama, kudingeka amasampula angaphambi kokusetshenziswa; kukhona ukuhlukahluka okuncane kombala we-batch-to-batch.
