Kwishyira hejuru-ya sima

Kwiyubaka-marimari ni ibikoresho byumye bivanze byifu. Nyuma yo gutunganywa, irashobora gukoreshwa nyuma yo kuvanga namazi kurubuga. Igihe cyose gisunitswe hamwe na scraper, uburinganire bwibanze bwibanze burashobora kuboneka. Ibiranga ni ibi bikurikira;

Umuvuduko ukomera urihuta, kandi urashobora kugenderaho mumasaha 24

Kuberako ikora vuba, ntabwo itakaza umwanya ukora indi mirimo.

Urebye ubuziranenge bwa minisiteri yo kwipimisha irashobora gucirwa urubanza ukurikije ibi bikurikira:

1. Amazi menshi, guhuriza hamwe, nta maraso no gutandukana.

2. Imbaraga nimbaraga zanyuma zo kwikuramo nyuma yo gusya byujuje ibisabwa

3. Igipimo cyo guhindura ibipimo ni gito (ni ukuvuga, nta kwaguka no kugabanuka).

4. Ukurikije igipimo gito cyamazi-sima, gifite rheologiya nziza;

5 ,, gera kurwego rwigihugu rwa 24h imbaraga zo kwikuramo zirenze 6.0MPa, imbaraga zoroshye zirenze 2.0MPa.

Kwiyubaka-sima yerekana formulaire

Ibikoresho byongeweho
42.5 300
plaster 50
calcium iremereye 150
Umusenyi 500
Ifu ya rubber 10
Polycarboxylate 0.5
sm 2.5
p803 0.5
mc400 0.7
Acide ya Tartaric 0.8
Umubare w'amazi wongeyeho ni 24% naho amazi agera kuri 145 ~ 148

Rimwe na rimwe, igihe cyo kuvanga kidahagije, hazaba ibibara byamavuta, ibibara byera, imvura, kuva amaraso, gutakaza ifu, imbaraga, nibindi, bigomba kwitabwaho mubikoresho fatizo bya formula. Reka tubisesengure umwe umwe.

A. Uburyo bwo kwirinda ibibara byamavuta

gukuramo aside tartaric

Kurugero, P803, ibi bikoresho bibisi bishobora gutera amavuta, mubisanzwe tubanza kuvanga P803 ninshuro 1 zumucanga ninshuro 1 ya calcium karubone kugirango tugabanye amavuta.

B, uburyo bwo kwirinda kugabanuka
1. Kugabanya ingano yo kugabanya amazi,
2. Ongera neza ingano ya selile ether yongeyeho,
3. Hindura urwego rwumucanga.

C, uburyo bwo kwirinda imbaraga zidahagije
1. Ingano ya sima ya alumina ndende ni mike, kandi imbaraga za 1d ntabwo zigeze kurwego rusanzwe;
2. Umubare w'ifu ya rubber ni muto cyane;
3. Abadindiza cyane bongerewe;
4. Sisitemu yo guhindagurika ntabwo ihagaze, bikaviramo kuva amaraso

D, uburyo bwo kwirinda ibibara byera
1. Ibice byongeweho birakabije
2. Hariho agglomeration yibikoresho fatizo.

E, ihame ryo kongera ibikoresho fatizo:
1. Kalisiyumu iremereye ivanze na sima ya alumina yo hejuru kugirango itange calcium karubonealuminate, ishobora kuzamura imbaraga zo kwikuramo.
2. Ibikoresho bigabanya amazi birashobora kugabanya ubwinshi bwamazi na sima, kandi bikongerera imbaraga nigihe kirekire cya beto;
3. Methyl selulose ikoreshwa nkibikoresho bigumana amazi kugirango wirinde neza inenge ya minisiteri yo kwisuzumisha itakaza amazi vuba kubera igicucu cyoroshye;
4. Gukoresha anhydrite nkigikorwa cyo kwagura no gukoresha hexanediol nkumukozi ugabanya guhuza kugirango yishyure neza kugabanuka. Iyi formulaire igereranya ikwirakwizwa rya buri kintu, kandi amazi ya sima yateguwe ashingiye ku kwipimisha minisiteri arenga 130mm muminota 20.
