Usimende-isihlabathi screed

Uyini screed phansi uyazi wonke umuntu, kodwa akuwona wonke umuntu uyasiqonda isidingo ke. Lesi sendlalelo Lesisemkhatsini kuyo ingumhlabathi for kokuphothula phansi, izinga ebusweni enamathela yokuphila ixhomeke. Ukuqondanisa izisekelo zamatshe, isitini netintfo longatibona, lapho umehluko ileveli kusuka 20 kuya 60 mm, isicelo usimende-isihlabathi screed. Ngalo kudala base iyunithi izinhlobo ezahlukene Uthwale phansi.

izinzuzo

Kuyinto ukuzinza Kuyaphawuleka nge enamathela usimende phansi ukudicilela, amafutha amaminerali, ezihogelwayo kanye nezinye izinto. Specific ingcindezi esiphezulu lapho usimende-isihlabathi elihlangana zingamelana kuyinto 600 N / sm.kv .. Ingase futhi usiphathe isilinganiso sezimoto umfutho enjoloba. Kepha umthelela ke it libhekene nokungabi khona kwanoma yiliphi chips nezinto eziwayo enesisindo esingaba amakhilogremu engaphansi kwemithathu. Ngenxa yalezi izakhiwo, ingasetshenziswa ukwenza izibopho emahhovisi, zokuhlala kanye emafektri, ezindaweni commercial futhi yezimboni.

isakhiwo

Usimende-isihlabathi screed siqukethe izithako ezilandelayo:

- encane ingxenyenamba isihlabathi;

- usimende (ngokuvamile Portland usimende);

- modifiers (plasticizers ezahlukene ukuncipha nabalawuli);

- spetsnapolniteli.

Ngenxa ukuqinisa esebenzisa fiberglass, ungakwazi bayakhohlwa oluqinisayo evamile we steel phansi rebar. Ngokuqondene ukulungisa adjuncts, ngenxa ekusebenziseni kwazo ekushintsheni izici physico-chemical ingxube, futhi kukhulisa abandayo ukumelana naso futhi kwenze ductility screed.

Ukwengezwa plasticizers kusiza ukunciphisa amanzi emzimbeni futhi peelability grout, wehlise izinga hydration futhi ivumela ukubeka usimende ukuqina lapho besanda kuqala, lapho kutholakala isakhiwo eyohlobo kakhudlwana futhi emihle grained. Screed usimende-isihlabathi esekelwe Portland usimende ingase isebenze njengendlela ungangenisi amanzi kanye anti-ukugqwala ungqimba. Uyovikela izisekelo ukhonkolo.

ukujiya

Ukushisa screed phansi akufanele kube ohlabayo kuka 5 cm; uma ekhona ukubunjwa plasticizers, akusiyo esingaphansi 3 cm. Uma enze bazihambisa ezindaweni eziningi kakhulu kufanele usebenzise amayunithi ekhethekile, ukusetshenziswa okuyinto enomthelela ukuncipha okukhulu kwesikhathi nomzamo. Kunezici eziningana ezinomthelela ukushuba screed:

- khona ungqimba ukwahlukanisa;

- degree of olubushelelezi base;

- uhlobo flooring.

zifudumele

It uyabulawa izinto obukhulu uyakwazi mthwalo, ezifana amaminerali uvolo noma polystyrene ukunwetshwa. Ngokusebenzisa e screeds amaminerali uvolo ukuminyana Kumelwe kungabi ngaphansi kuka 150-170 kg / m³, kanye kwabantu styrofoam -. Hhayi ngaphansi kuka 35. abahlukahlukene yashayisa unqenqema ekuvikeleni (foam ingilazi, Perlite, penolistirol), ingilazi esetshenziswa on emabhilidini, okuyinto akhiwa joists. ingasetshenziswa Expanded ubumba udoti, kodwa uma eqhathaniswa polystyrene, kuba ukwahlukanisa kangako, futhi ukuthola isilinganiso kudingekile ukwenza mayelana 30 cm backfill.
