Tebulo lamagalimoto loyenda pa matope a simenti

NLB-3 mtundu wa Smemer Stemer Tester / Medioni Yoyendayenda ya Cementar National amakwaniritsa zofunikira za JC / T Standard ndipo imagwiritsidwa ntchito poyesa madzi a simenti.

Zolinga Zaukadaulo:

1.Total kulemera kwa gawo la Beats: 4.35kg ± 0.15kg

2. Kutalikirana: 10mm ± 0,2mm

3. Kuyenda pafupipafupi: 1 nthawi / s

4..

5. Net kulemera: 21kg

Chithunzi:

Mafuta a simenti amalumpha (omwe amadziwikanso kuti simenti madzi amtundu wa sitepe) amagwiritsidwa ntchito poyesa madzi atsopano a GB / T2419-2005. Ndiye muyezo wokha muyezo womwewu. ndi zida.

Malangizo:

1. Lumikizani pulagi kupita ku dzenje lolingana la contrant, ndikulumikizani cholumikizira ku magetsi. Ngati kulumphadumpha sikugwiritsidwa ntchito pasanathe maola 24, koyambirira kudumphira nthawi 25 pozungulira.

2. Zipangizo ndi zochuluka kuti muyesedwe mayeso amodzi: simenti 300 magalamu, mchenga, madzi: kuwerengetsa molingana ndi kuchuluka kwa gawo la simenti. Kupanga matope kumachitika molingana ndi malamulo oyenera a GB / G17671.

3. Ikani matope osakanikirana ndi nkhungu msanga m'magawo awiri. Choyambira choyambirira chimayikidwa pafupifupi magawo awiri mwa atatu a kutalika kwa cene. Gwiritsani ntchito mpeni kuti mupange kasanu pamitundu iwiri yokhazikika, kenako gwiritsani ntchito yotumphuka. Ndodo imasungidwa nthawi 15 kuchokera kumphepete mpaka pakati. Kenako ikani matope a matope, omwe ali pafupifupi 20mm apamwamba kuposa cholumikizira chozungulira. Mofananamo, gwiritsani ntchito mpeni kuti mupange kasanu mmayendedwe awiri mogwirizana, kenako gwiritsani ntchito thumbo kuti lizikhala m'mphepete mpaka 10. Kuzama koyamba kwa kuyamwa kwamphamvu kumakhazikika kwa theka la kutalika kwa matope, ndipo kachiwiri wosanjikiza watulutsidwa mpaka pano kuposa pamwamba pa osanjikiza. Kukhazikika kwa ndodo yolumikizira kuli molingana ndi zomwe zalembedwazo 6.3 mu GB / T2419-2005 "Kutsimikiza za madzi a simenti".

4. Pambuyo potchera, chotsani malaya ake, ndikupukuta mpeni, ndikupukuta matope omwe ali apamwamba kuposa mbali imodzi mpaka m'mphepete, ndikupukuta matope omwe amagwera patebulo. Kwezani chingwe chowuma ndikuchotsa pang'ono pang'ono. Kanikizani batani la "Start" la counter kuti mumalize kuzungulira 25.

5. Pambuyo pa kugunda kwatsirizidwa, gwiritsani ntchito rucnier caliper ndi 300mm kuti muyezenso kukula kwa mchenga pansi panjira ziwiri, tengani manambala, ndikuwonetsa mu Mm. Mtengo wapakati ndi utoto wamtundu wa simenti.

6. Mayeso ayenera kumaliza mkati mwa mphindi 6 kuyambira pachiyambi cha kuwonjezera madzi kumatayi mpaka kumapeto kwa muyezo wa diameter.

Njira Zogwira Ntchito:

1) Onani ngati magetsi athe ntchito musanagwiritse ntchito, ndikuchita masewera kuti muone ngati chinthu chilichonse chowongolera chimagwira ntchito bwino.

2) Konzani zitsanzozo malinga ndi lingaliro, pukutani patebulopo pamwamba, khoma lamkati la nkhungu.

3) Ikani matope osakanikirana mwa mayeso oyesedwa m'magawo awiri. Kutalika kwa gawo loyamba ndi 2/3. Gwiritsani ntchito mpeni kuti mujambule kasanu mbali zonse, ndikugwiritsa ntchito mpeni wawung'ono kuti mujambule ka 10 ndikusindikiza ka 10. Gulani nkhungu.

4) kwezani mayesowo akuwumba molunjika, yambitsani pinki yolumpha, ndikudumphira mkati mwa 30 ± 1s.

5) Kuwomba kumamalizidwa, gwiritsani ntchito ma calipers kuti muyezenso mainchesi pansi ndi mainchesi mu njira yolunjika, ndipo mtengo wamba umawerengedwa ngati madzi a simenti ndi madzi. Mayeso amayenera kumaliza mkati mwa mphindi 5.

6) Nthawi zonse khalani ndi zigawo zonse zovomerezeka miyezi isanu ndi umodzi iliyonse.
