Nigute ushobora kugerageza umubare wo kugabanya amazi ya minisiteri?

1. Ibirimo hamwe nuburyo bwo gusaba

Ubu buryo bugaragaza ibishoboka byose nintambwe yo kugena amazi ya sima.

Ubu buryo bukoreshwa mu kugena amazi ya minisiteri y'ingwate y'ivuru ry'ibirunga, sima y'Abaporland ivanze n'ivu ry'ivu ry'ibirunga, sima ya Portland ivanze n'ivu ry'ibirunga, sima ya Shog n'ubundi bwoko bwa cemet n'ubundi bwoko bwa cement bwagenewe gukoresha ubu buryo.

2. Ibipimo ngenderwaho

GB177 COVILE Imbaraga Imbaraga

GB178 umucanga usanzwe kugirango wipimire

Jbw 01-12 Icyitegererezo cya Standation ya sima Burtar

3. Uburyo bwo gutahura bwo kugabanya amazi ya minisiteri ni ku buryo bukurikira:

3.1 Ibikoresho n'ibikoresho

A. Mixtor Mixer;

B. Imbonerahamwe yo gusimbuka (5m isahani yikirahure igomba kongerwaho);

C. Cylindrical Ramming Bar: Bikozwe mubintu byicyuma, diameter 20mm, uburebure bugera kuri 185mm;

D. Gutwarwa Cone Roull Mold Mold na Mold Cover Mold Ingano, uburebure ni 60 ± 0.5mm, igifuniko cyaka

E. Umutegetsi (gupima intera 300mm) cyangwa kalipers hamwe no gupima intera 300mm;

F. SPATula.

G. Amafaranga asigaye (apima 1000g, yumvise 1G).

3.2. Uburyo bw'ikizamini

3.2.1 Gupima gukoresha amazi ya minisiteri

A. Gupima 300g sima na 750g basanzwe basutse mu nkono ivanze, tangira ivanga, ongeraho amazi buhoro buhoro nyuma yo kuvanga 5s, hanyuma ukongereho muri 30. Reka gukangurira 3mins nyuma yo gutangira imashini. Kuzamura minisiteri kuruhande hanyuma ukureho isafuriya.

B. Mu kuvanga minisiteri icyarimwe, hamwe nigitambaro gitose cyo gusiba imbonerahamwe yo gusimbuka, inzara ya rane, ikata urukuta rwimbere hamwe nigitambaro cyimbere, hanyuma ubishyire hagati yisahani yikirahure, gitwikiriwe nigitambaro bitose.

C. MIRERING ivanze igabanijwemo byihuse muburyo bubiri muburyo bwa cone ibijyanye na bibiri bya kabiri, hanyuma bipakira hamwe na santimetero ya kabiri, hanyuma bipakirwa na croser ya kabiri, hanyuma bipakirwa na crotir ya minishi, hanyuma bipakira hamwe na santimetero ya kabiri, hanyuma ushyire hamwe na cillirteur kuri mold, hejuru ya silindrike inshuro cumi n'itanu. Iyo upakiye umucanga no kwinjiza umusenyi, kanda kuri Trincate Cone apfa nintoki kugirango wirinde kugenda.

D. Nyuma yo gufungura, gukuramo igifuniko cya mold, koresha spatula kugirango ushiremo minisiteri iri hejuru yimodoka yagabanijwe hanyuma uhanagure neza, hanyuma uzamure witonze hejuru. Kunyeganyeza ibiganza hamwe na crank y'uruziga kugirango usimbukire gusimbuka inshuro mirongo itatu ku gipimo cya kimwe.

E. Nyuma yo gushyushya, koresha calipers kugirango upime diamet ya diffusion epfo hasi, hanyuma ufate agaciro kagereranijwe ka diamefri ebyiri kurindi nka minisiteri mugihe amazi akoreshwa, agaragazwa muri Mm. Iyo minisiteri ikwirakwije ari 140 ± 5mm, gukoresha amazi ni ugukoresha amazi yerekanwe kuri minisiteri.

3.2.2 ukurikije uburyo 3.2.1, gukoresha amazi ya minisiteri hamwe numukozi ugabanya amazi wageze 140 ± 5mm.

3.3. Umubare w'amazi wo kugabanya minisiteri yavuwe ku buryo bukurikira:

Umubare wo kugabanya amazi ya minisiteri (%) = (w0-w1) / w0 × 100

Aho, W0 - Gukoresha amazi (G) mugihe ukwirakwije Pertar ari 140 ± 5mm;

W1 - Kunywa amazi (G) mugihe ukwirakwije minisiteri hamwe numukozi ugabanya amazi ni 140 ± 5mm.

Agaciro ko kugabanya amazi nigipimo cyimibare bisobanura agaciro k'ibyitegererezo bitatu.
