Solf-leveling mortar ivhu rakaoma-musanganiswa wehupfu. Mushure mekugadzirisa, inogona kushandiswa mushure mekusanganiswa nemvura panzvimbo. Chero bedzi iyo inosundirwa kure ne scraper, nzvimbo yepamusoro yepamusoro inogona kuwanikwa. Maitiro acho ndeaya anotevera;
Iyo yekuomesa inomhanya inokurumidza, uye unogona kufamba pairi mukati memaawa makumi maviri nemana
Nekuti inoshanda nekukurumidza, haina kutambisa nguva kuita rimwe basa.
Kutonga mhando yedhaka yekuzvimisa inogona kutongwa kubva pane zvinotevera zvinhu:
1. High fluidity, kubatana, kusabuda ropa uye kuparadzana.
2. Simba uye simba rekupedzisira rekumanikidza mushure mekugaya zvinosangana nezvinodiwa
3. The dimensional shanduko mwero idiki (ndiko kuti, hapana kuwedzera uye hapana shrinkage).
4. Pasi pemamiriro ekuderera kwemvura-cement ratio, ine rheology yakanaka;
5,, kusvika pachiyero chenyika che 24h yekumanikidza simba rakakura kupfuura 6.0MPa, flexural simba rakakura kupfuura 2.0MPa.

Huwandu hwemvura yakawedzerwa i24% uye fluidity inosvika 145 ~ 148
Dzimwe nguva kana nguva yekusanganiswa isina kukwana, pachava nemafuta mavara, mavara machena, kunaya, kubuda ropa, kurasikirwa kweupfu, simba, nezvimwewo, izvo zvinoda kubhadharwa muzvinhu zvakasvibiswa zvefomu. Ngationgororei imwe neimwe.
A. Nzira yekudzivirira mafuta mavara
bvisa tartaric acid
Semuenzaniso, P803, iyi mbishi inogona kukonzera mafuta mavara, isu tinowanzo pre-kusanganisa P803 ne1 nguva yejecha uye 1 nguva yecalcium carbonate kuderedza mafuta mavara.
B, sei kudzivirira subsidence
1. Deredza huwandu hwemvura inoderedza agent,
2. Wedzera zvakafanira huwandu hweselulosi ether yakawedzerwa,
3. Rongedza kukwira kwejecha.
C, nzira yekudzivirira simba risina kukwana
1. Kuwanda kwepamusoro alumina simenti yakaderera, uye simba re1d harina kusvika pachiyero;
2. Huwandu hwehupfu hwerabha hwakanyanya kuderera;
3. Retarder yakawandisa inowedzerwa;
4. Nzira yekugadzira haina kugadzikana, zvichiita kuti kubuda kweropa
D, nzira yekudzivirira mavara machena
1. Izvo zvinowedzera zvimedu zvakakora zvakanyanya
2. Pane agglomeration yezvinhu mbishi.
E, musimboti wekuwedzera kwezvinhu:
1. Heavy calcium inosanganiswa ne high alumina simenti kuti ibudise calcium carbonoaluminate, iyo inogona kuvandudza simba rekumanikidza.
2. Mvura inoderedza mumiririri inogona kuderedza kuwanda kwemvura uye simenti, nekuvandudza simba uye kusimba kwekrete;
3. Methyl cellulose inoshandiswa sechinhu chekuchengetedza mvura kuti ibudirire kudzivirira kukanganisa kwega-leveling mortar iyo inorasikirwa nemvura nokukurumidza nekuda kwekuyerera kwakaonda;
4. Kushandisa anhydrite sechinhu chekuwedzera uye kushandisa hexanediol sechinhu chinoderedza synergizes kuti ibudirire kubhadhara shrinkage. Iyi fomula inoongorora chiyero chekugovera chechikamu chimwe nechimwe, uye kuyerera kweiyo yakagadzirwa simende-yakavakirwa-yega-yega-leveling dhaka yakakura kupfuura 130mm mumaminetsi makumi maviri.
