Tondo wodzipangira yekha nthawi zambiri amagwiritsidwa ntchito pokongoletsa pansi. Kudziwongolera kumakhala ndi madzi abwino, osang'ambika, osabowola, ndipo kumatha kuteteza pansi.
Mitundu imaphatikizapo imvi ya simenti yachilengedwe, yofiira, yobiriwira, etc. Mitundu ina imathanso kusinthidwa malinga ndi zomwe mumakonda.
Kumangako ndi kosavuta, kungagwiritsidwe ntchito mutatha kuwonjezera madzi ndi kusonkhezera, ndipo imatha kufalikira mofulumira pansi kuti mupeze malo apamwamba.

Kupangidwa kwa simenti yodziyimira payokha
Simenti yodziyimira payokha, yomwe imadziwikanso kuti matope odziyimira pawokha, ndi chinthu chopangidwa ndi simenti yolimba ngati maziko ndipo chimaphatikizidwa kwambiri ndi zida zina zosinthidwa. Mtondo wa simenti womwe ulipo wodziyimira uli ndi mitundu yosiyanasiyana, koma mawonekedwe ake ndi ofanana.
Limakhala ndi magawo asanu ndi limodzi:
1. Zosakaniza za gelling
Pali makamaka mitundu itatu ya simenti yapamwamba ya alumina, simenti wamba ya Portland, ndi a-hemihydrate gypsum/anhydrite, yowerengera 30% -40%.
2. Mineral filler
Makamaka mchenga wa quartz ndi ufa wa calcium carbonate, wowerengera 55% -68%.
3. Coagulant regulator
Makamaka retarder - tartaric acid, coagulant - lithiamu carbonate ndi superplasticizer - superplasticizer, yowerengera 0.5%.
4. Kusintha kwa Rheology
Makamaka defoamers ndi stabilizers, ndalama 0.5%.
5. Zida zowonjezera
Makamaka redispersible polima ufa, mlandu 1% -4%.
6. Madzi
Malinga ndi chilinganizo ayenera kuwonjezera mlingo woyenera wa madzi kupanga kudziona leveling matope.
Encyclopedia yodziyimira payokha ya simenti ya matope:
Chinsinsi chimodzi
28% wamba pakachitsulo simenti 42.5R, 10% mkulu alumina simenti CA-50, 41.11% khwatsi mchenga (70-140 mauna), 16.2% calcium carbonate (500 mauna), 1% hemihydrate gypsum, 6% anhydrous gypsum (yolimba Gypsumu) .
Chinsinsi awiri
26% Portland simenti 525R, 10% high-aluminium simenti, 3% laimu, 4% anhydrite zachilengedwe, 4421% quartz mchenga (01-03mm, mchenga wa silika ndi wabwino chifukwa cha madzi ake abwino), 10% Calcium carbonate (40- 100um), 0.5% superplasticizer (melamine, Peramin SMF 10), 0.2% tartaric acid kapena citric acid, 01% defoamer P803, 004% lithium carbonate (<40um), 01% sodium carbonate, 005%cellulose ether(200-500mPas), 22-25% madzi.
Zofunikira pakugwira ntchito kwa dothi la simenti lodziyimira pawokha
Mtondo wodziyimira pawokha wa simenti uli ndi zofunikira zina, kuphatikiza madzimadzi, kukhazikika kwa slurry, mphamvu zopondereza, ndi zina zambiri:
1. Kuchuluka kwa madzi: Nthawi zambiri, madziwa ndi aakulu kuposa 210 ~ 260mm.
2. Kukhazikika kwa Slurry: Thirani slurry wosakanizika pa mbale yagalasi yoyikidwa molunjika, ndipo muwone pambuyo pa mphindi 20. Sipayenera kukhala kutuluka magazi, kusanjana, kupatukana, ndi kubwebweta.
3. Mphamvu yopondereza: Mphamvu yopondereza ya matope wamba wamba ya simenti ili pamwamba pa 15MPa, ndipo mphamvu yopondereza ya konkire ya simenti ili pamwamba pa 20MPa.
4. Flexural mphamvu: The flexural mphamvu ya mafakitale self-leveling matope simenti ayenera kukhala wamkulu kuposa 6Mpa.
5. Nthawi ya coagulation: Pambuyo potsimikizira kuti slurry imagwedezeka mofanana, onetsetsani kuti nthawi yogwiritsira ntchito ndi yoposa mphindi 40, ndipo kugwira ntchito sikungakhudzidwe.
6. Kukana kwamphamvu: Tondo la simenti lodziyimira palokha liyenera kulimbana ndi kugunda kwa thupi la munthu ndi zinthu zonyamulidwa mumsewu wamba, ndipo kukana kwa nthaka kumakhala kwakukulu kuposa kapena kofanana ndi 4 joules.
7. Kumangirira kulimba kwamphamvu kugawo loyambira: Kumangirira kwamphamvu kwazinthu zodziyimira pawokha pansi pa simenti nthawi zambiri kumakhala pamwamba pa 0,8 MPa.
Makhalidwe a matope odzipangira okha:
1. Imakhala ndi madzi abwino, imafalikira mofanana, ndipo imatha kuyenda bwino mumipata ya mapaipi otenthetsera pansi.
2. Mtondo wokhazikika wokhazikika umagawidwa mofanana ndipo uli ndi mphamvu zabwino zotsutsana ndi tsankho.
3. Kapangidwe kake ka matope odziyimira pawokha kumathandizira kuti pakhale kutentha kofananako, komwe kumatha kuwonetsetsa kuti kutentha kumayendera bwino.
4. Mphamvu yapamwamba, kuuma mofulumira, kawirikawiri masiku 1-2 angagwiritsidwe ntchito.
5. Mlingo wa shrinkage ndi wotsika kwambiri, ndipo sikophweka kung'amba, kung'amba ndi kubisala.
Kugwiritsa ntchito matope odzipangira okha:
Mtondo wodziyimira pawokha umagwiritsidwa ntchito makamaka pakukongoletsa pansi kwa nyumba zamakono. Ili ndi mawonekedwe a flatness apamwamba, madzi abwino komanso osasweka, ndipo amakondedwa kwambiri ndi eni ake ambiri.
Malo odzipangira okha ndi osasunthika onse, odzipangira okha, nthaka ndi yosalala, yosalala komanso yokongola; osalowa fumbi, osalowa madzi, osavuta kuyeretsa; kukana bwino kwa dzimbiri, kukana kwa asidi ndi alkali, kukana kuvala, kukana kupsinjika, kukana kukhudzidwa, komanso kulimba kwina.
Kagwiritsidwe ndi mawonekedwe ogwiritsira ntchito:
1. Kudzipangira simenti kumagwiritsidwa ntchito ngati maziko apamwamba a epoxy pansi, polyurethane floors, PVC coils, mapepala, mphira pansi, matabwa olimba, ndi mbale za diamondi.
2. Simenti yodziyimira pawokha ndi chinthu chophwanyika chomwe chiyenera kugwiritsidwa ntchito poyika ma coil a PVC pamalo opanda phokoso komanso opanda fumbi pazipatala zamakono.
3. Kudziikira simenti kumagwiritsidwanso ntchito m’zipinda zaukhondo, zapansi zopanda fumbi, pansi zolimba, ndi pansi m’mafakitale a zakudya, m’mafakitale opangira mankhwala, ndi m’mafakitale a zamagetsi olondola.
4. Polyurethane zotanuka pansi m'munsi wosanjikiza kwa kindergartens, makhoti tennis, etc. Monga m'munsi wosanjikiza asidi ndi alkali kugonjetsedwa pansi pa mafakitale zomera ndi kuvala zosagwira pansi. Pamwamba pa roboti. Pansi panyumba yokongoletsera pansi.
5. Mipata yosiyanasiyana ya m'madera ambiri imaphatikizidwa ndi kusanjidwa. Monga holo zabwalo la ndege, mahotela akulu, ma hypermarket, masitolo akuluakulu, maholo amisonkhano, mawonetsero, maholo, malo oimikapo magalimoto, ndi zina zotero zimatha kumaliza mwamsanga malo apamwamba.
