Mtondo wodziyimira pawokha ndi chinthu chowuma chosakanizika cha ufa. Pambuyo pokonza, ingagwiritsidwe ntchito mutatha kusakaniza ndi madzi pamalopo. Malingana ngati akukankhira kutali ndi scraper, malo apamwamba kwambiri amatha kupezeka. Makhalidwe ake ndi awa;
Liwiro loumitsa ndilofulumira, ndipo mutha kuyenda pamenepo mkati mwa maola 24
Chifukwa zimagwira ntchito mwachangu, sizikutaya nthawi pogwira ntchito zina.
Kuweruza mtundu wa matope odziyimira pawokha kungayesedwe kuchokera kuzinthu izi:
1. Kuchuluka kwamadzimadzi, kugwirizanitsa, kusataya magazi komanso kulekanitsa.
2. Mphamvu ndi mphamvu yomaliza yopondereza pambuyo pogaya zimakwaniritsa zofunikira
3. Mlingo wosinthika wa dimensional ndi wocheperako (ndiko kuti, palibe kukulitsa komanso kuchepera).
4. Pansi pa chiŵerengero chochepa cha simenti ya madzi, imakhala ndi rheology yabwino;
5,, kufika muyezo dziko 24h compressive mphamvu wamkulu kuposa 6.0MPa, flexural mphamvu kuposa 2.0MPa.
Fomula yodziyimira payokha ya simenti
Zopangira Zowonjezera Zowonjezera
42.5 300
pulasitala 50
calcium yochuluka 150
Mchenga 500
Mpira unga 10
Polycarboxylate 0.5
sm 2.5
p803 0.5
mc400 0.7
Asidi a Tartaric 0.8
Kuchuluka kwa madzi owonjezera ndi 24% ndipo fluidity imafika 145 ~ 148
Nthawi zina ngati kusakaniza nthawi sikokwanira, padzakhala mawanga mafuta, mawanga oyera, mpweya, magazi, imfa imfa, mphamvu, etc., amene ayenera kulabadira mu zopangira chilinganizo. Tiyeni tiwasanthule limodzi ndi limodzi.
A. Momwe mungapewere mawanga amafuta
kuchotsa tartaric acid
Mwachitsanzo, P803, izi zopangira zimatha kuyambitsa mawanga amafuta, nthawi zambiri timasakaniza P803 ndi mchenga 1 ndi 1 nthawi ya calcium carbonate kuti tichepetse mawanga amafuta.
B, momwe mungapewere kuchepa
1. Chepetsani kuchuluka kwa zochepetsera madzi,
2. Wonjezerani bwino kuchuluka kwa cellulose ether yomwe yawonjezeredwa,
3. Sinthani kachulukidwe ka mchenga.
C, momwe mungapewere mphamvu zosakwanira
1. Kuchuluka kwa simenti yapamwamba ya alumina ndi yochepa, ndipo mphamvu ya 1d siili yoyenera;
2. Kuchuluka kwa ufa wa rabara ndi wotsika kwambiri;
3. Kuchepetsa kwambiri kumawonjezeredwa;
4. Dongosolo la kupanga ndi losakhazikika, zomwe zimapangitsa kuti magazi azingoyenda okha
D, momwe mungapewere mawanga oyera
1. Zowonjezera particles ndi coarse kwambiri
2. Pali agglomeration ya zipangizo.
E, mfundo zowonjezera zowonjezera:
1. Kashiamu wolemera amasakanikirana ndi simenti yapamwamba ya aluminiyamu kuti apange calcium carbonoaluminate, yomwe ingapangitse mphamvu yopondereza.
2. Njira yochepetsera madzi imatha kuchepetsa kuchuluka kwa madzi ndi simenti, ndikuwongolera mphamvu ndi kulimba kwa konkriti;
3. Methyl cellulose imagwiritsidwa ntchito ngati madzi osungira madzi kuti apewe bwino chilema cha matope odzipangira okha omwe amataya madzi mwamsanga chifukwa cha kusungunuka kochepa;
4. Kugwiritsa ntchito anhydrite monga chowonjezera ndi kugwiritsa ntchito hexanediol monga kuchepetsa wothandizira synergizes kuti athetse bwino kuchepa. Njirayi imayang'ana kuchuluka kwa gawo lililonse, ndipo madzi amadzimadzi a matope odzipangira okha simenti amapitilira 130mm mphindi 20.
