1. Chiyambi ndi gulu la simenti / matope odzipangira okha
Simenti / matope odziyimira pawokha ndi mtundu womwe ungapereke malo ophwanyika komanso osalala pansi pomwe mapeto omaliza (monga carpet, pansi pamatabwa, etc.) akhoza kuikidwa.Zofunikira zake zazikulu zimaphatikizira kuuma mwachangu komanso kuchepa pang'ono.Pali njira zosiyanasiyana zapansi pamsika monga zopangira simenti, gypsum kapena zosakaniza zake.M'nkhaniyi tiona kachitidwe flowable ndi kusanja katundu.Flowable hydraulic ground (ngati ikugwiritsidwa ntchito ngati chivundikiro chomaliza, imatchedwa pamwamba; ngati ikugwiritsidwa ntchito ngati gawo lapakati, imatchedwa cushion material) nthawi zambiri imatchedwa: simenti-based self-leveling. pansi (wosanjikiza pamwamba) ndi pansi pa simenti yodziyimira pawokha (nsanjika ya khushoni) ).
2. Kupanga zinthu zakuthupi ndi chiŵerengero chambiri
Simenti / matope odziyimira pawokha ndi chinthu chopangidwa ndi simenti yolimba kwambiri yopangidwa ndi simenti monga maziko ake komanso kuphatikiza kwambiri ndi zinthu zina zosinthidwa.Ngakhale mitundu yosiyanasiyana yomwe ilipo pano ndi yosiyana komanso yosiyana, koma mwazinthu zonse zida
Osasiyanitsidwa ndi mitundu yomwe ili pansipa, mfundoyi ndi yofanana.Amapangidwa makamaka ndi magawo asanu ndi limodzi otsatirawa: (1) zosakaniza za simenti, (2) mineral filler, (3) coagulation regulator, (4) rheology modifier, (5) chigawo chothandizira, (6) kapangidwe kamadzi, zotsatirazi ndi zofananira za ena opanga.

(1) Dongosolo lake la simenti nthawi zambiri limapangidwa ndi simenti wamba ya Portland (OPC), simenti yayikulu ya alumina (CAC) ndi calcium sulfate, kuti ipereke calcium, aluminiyamu ndi sulfure yokwanira kupanga miyala ya calcium vanadium.Izi zili choncho chifukwa mapangidwe a miyala ya calcium vanadium ali ndi makhalidwe akuluakulu atatu, omwe ndi (1) liwiro la mapangidwe, (2) mphamvu yomanga madzi ambiri, ndi (3) kuthekera kowonjezera shrinkage, yomwe imagwirizana kwambiri ndi macroscopic -Kuyika simenti / matope ayenera kupereka Amafuna.
(2) Kusankha kwa tinthu tating'ono ta simenti/matope kumafunikira kugwiritsa ntchito zodzaza zokulirapo (monga mchenga wa quartz) ndi zodzaza bwino (monga ufa wa calcium carbonate) kuphatikiza kuti mukwaniritse bwino kwambiri.
(3) Kashiamu sulphate yopangidwa mu simenti / matope odzipangira okha ndi -hemihydrate gypsum (-CaSO4•½H2O) kapena anhydrite (CaSO4);amatha kutulutsa ma sulphate radicals pamlingo wokwanira popanda kuwonjezera kumwa madzi.Funso lomwe nthawi zambiri limafunsidwa ndi chifukwa chake -hemihydrate gypsum (yomwe ili ndi mankhwala ofanana ndi -hemihydrate), omwe amapezeka mosavuta komanso otsika mtengo kuposa -hemihydrate, sangathe kugwiritsidwa ntchito.Koma vuto ndiloti chiŵerengero chopanda kanthu cha -hemihydrate gypsum chidzawonjezera kwambiri madzi akumwa, zomwe zidzachititsa kuti kuchepa kwa mphamvu ya matope owuma.
(4) Redispersible rubber powder ndiye chigawo chachikulu cha simenti / matope odzipangira okha.Ikhoza kusintha fluidity, kukana abrasion pamwamba, mphamvu yokoka ndi mphamvu flexural.Kuphatikiza apo, amachepetsa modulus ya elasticity, potero amachepetsa kupsinjika kwamkati kwadongosolo.Redispersible mphira ufa uyenera kupanga mafilimu amphamvu a polima.Zopangira zodzitchinjiriza za simenti/matope zimakhala ndi ufa wofikira 8% wogawanikanso, ndipo makamaka ndi simenti ya aluminiyamu wapamwamba kwambiri.Izi zimatsimikizira kuuma kofulumira komanso mphamvu zoyambilira pambuyo pa maola 24, motero kukwaniritsa zofunikira pa ntchito yomanga tsiku lotsatira, monga kukonzanso ntchito.
(5) Self-leveling simenti / matope kumafuna kukhazikitsa accelerators (monga lithiamu carbonate) kuti akwaniritse mphamvu ya simenti yoyambirira, ndi zochepetsera (monga tartaric acid) kuti achepetse kuthamanga kwa gypsum.
(6) Superplasticizer (polycarboxylate superplasticizer) imagwira ntchito ngati chochepetsera madzi mu simenti yodziyimira payokha / matope motero imapereka magwiridwe antchito komanso kusanja.
(7) The defoamer sangathe kuchepetsa mpweya ndi kupititsa patsogolo mphamvu yomaliza, komanso kupeza yunifolomu, yosalala komanso yolimba pamwamba.
(8) Kuchuluka kwa stabilizer (monga cellulose ether) kungalepheretse kupatukana kwa matope ndi mapangidwe a khungu, motero kumapangitsa kuti pakhale vuto lomaliza.Mafuta a mphira opangidwanso amathandizira kupititsa patsogolo kayendedwe kake komanso kumathandizira kukhala wamphamvu.
4. Zofunikira zamtundu wazinthu ndi matekinoloje ofunikira
4.1.Zofunikira zodziyimira pawokha simenti/matope
(1) Imakhala ndi madzi abwino, ndipo ili ndi malo abwino owongolera ngati makulidwe a mamilimita angapo, ndipo
The slurry ali ndi kukhazikika bwino, kotero kuti akhoza kuchepetsa zochitika zoipa monga tsankho, delamination, magazi, ndi kuwira.
Ndipo m'pofunika kuonetsetsa nthawi yokwanira yogwiritsiridwa ntchito, nthawi zambiri yopitilira mphindi 40, kuti ntchito yomanga ipite patsogolo.
(2) Kupendekeka kwabwinoko, ndipo pamwamba pake palibe cholakwika chilichonse.
(3) Monga zinthu zapansi, mphamvu zake zopondereza, kukana kuvala, kukana kukhudzidwa, kukana madzi ndi makina ena akuthupi
Ntchitoyi iyenera kukwaniritsa zofunikira za malo omangira m'nyumba.
(4) Kukhalitsa ndikwabwinoko.
(5) Ntchito yomanga ndi yosavuta, yachangu, yopulumutsa nthawi komanso yopulumutsa ntchito.
4.2.Zaumisiri zazikulu zodzipangira simenti/matope
(1) Kuyenda
Fluidity ndi chizindikiro chofunikira chowonetsa magwiridwe antchito a simenti / matope odzipangira okha.Nthawi zambiri, fluidity ndi wamkulu kuposa 210-260mm.
(2) Kukhazikika kwamatope
Mlozerawu ndi mlozera womwe ukuwonetsa kukhazikika kwa simenti/matope odzipangira okha.Thirani slurry wosakaniza pa galasi mbale anaika yopingasa, onani pambuyo mphindi 20, sipayenera kukhala zoonekeratu magazi, delamination, tsankho, kuwira ndi zochitika zina.Mlozerawu umakhudza kwambiri momwe zinthu zilili komanso kulimba kwa zinthu pambuyo poumba.
(3) Mphamvu zopanikiza
Monga zinthu zapansi, chizindikirochi chiyenera kutsata ndondomeko yomanga pansi pa simenti, malo amtundu wamba wamba.
Mphamvu yopondereza ya pansi yoyamba imayenera kukhala pamwamba pa 15MPa, ndipo mphamvu yopondereza ya konkire ya simenti ili pamwamba pa 20MPa.
(4) Mphamvu yosinthasintha
Mphamvu yosinthika ya simenti yodziyimira pawokha / matope iyenera kukhala yayikulu kuposa 6Mpa.
(5) Coagulation nthawi
Pakukhazikitsa nthawi yodzipangira simenti / matope, mutatsimikizira kuti slurry imagwedezeka mofanana, onetsetsani kuti nthawi yogwiritsira ntchito ndi yoposa mphindi 40, ndipo kugwira ntchito sikudzakhudzidwa.
(6) Kukana kwamphamvu
Simenti / matope odziyimira pawokha akuyenera kupirira kukhudzidwa kwa thupi la munthu ndi zinthu zonyamulidwa pamagalimoto abwinobwino, ndipo kukana kwa nthaka ndikokulirapo kuposa kapena kofanana ndi ma joules 4.
(7) Kuvala kukana
Simenti / matope odziyimira pawokha ngati zinthu zapansi ziyenera kupirira kuchuluka kwa magalimoto.Chifukwa cha kusanjikiza kwake kocheperako, pansi pa nthaka ikakhala yolimba, mphamvu yake yonyamula imakhala pamtunda, osati pa voliyumu.Choncho, kukana kwake kuvala n'kofunika kwambiri kuposa mphamvu yopondereza.
(8) Gwirizanitsani kulimba kwamphamvu kugawo loyambira
Mphamvu yolumikizana pakati pa simenti / matope odziyimira pawokha ndi gawo loyambira limagwirizana mwachindunji ngati padzakhala dzenje ndi kugwa pambuyo powumitsidwa slurry, zomwe zimakhudza kwambiri kulimba kwa zinthuzo.Muzomangamanga zenizeni, tsukani wothandizila wapansi kuti afikire chikhalidwe chomwe chili choyenera kwambiri pomanga zipangizo zodzipangira okha.Kulimba kwamphamvu kwazinthu zodziyimira pawokha simenti kunyumba nthawi zambiri kumakhala pamwamba pa 0.8MPa.
(9) Kulimbana ndi mng’alu
Kulimbana ndi Crack ndi chizindikiro chachikulu cha simenti / matope odzipangira okha, ndipo kukula kwake kumagwirizana ndi ngati pali ming'alu, kung'ambika, ndi kugwa pambuyo poti zinthu zodziyimira pawokha zalimba.Kaya mutha kuwunika molondola kukana kwa ming'alu ya zida zodzipangira zokha zimagwirizana ndi ngati mutha kuwunika bwino kupambana kapena kulephera kwa zinthu zodzipangira nokha.
5. Kumanga simenti / matope odzipangira okha
(1) Chithandizo chamankhwala
Tsukani maziko kuti muchotse fumbi loyandama, madontho amafuta ndi zinthu zina zomangirira.Ngati pali maenje akuluakulu m'munsi mwake, kudzaza ndi kusanja kumafunika.
(2) Chithandizo chapamwamba
Ikani malaya a 2 ogwiritsira ntchito mawonekedwe apansi pamtunda woyeretsedwa.
(3) Kumanga molingana
Werengani kuchuluka kwa zipangizo zosiyanasiyana malinga ndi kuchuluka kwa zipangizo, chiŵerengero cha madzi olimba (kapena chiŵerengero cha madzi olimba) ndi malo omangira, gwedezani mofanana ndi chosakanizira, tsanulirani slurry pansi, ndipo pang'onopang'ono pani chiputu.
(4) Kuteteza
Ikhoza kusungidwa molingana ndi zofunikira za zipangizo zosiyanasiyana zodzipangira.
