Gịnị bụ ndị Efrata ciment?

Cement - otu n'ime ihe ndị bụ isi ụlọ ihe eji na mpaghara ebe a kemgbe oge ochie. The cement mejupụtara na-agụnye a ọnụ ọgụgụ nke inorganic bekee nke na kọntaktị na mmiri na-etolite a na-akpọ ngwọta. Na a nso nke kpọmkwem ahụ àgwà, mgbe akọrọ ngwọta siri ike.

Cement na-emepụta na ọtụtụ ụzọ, ma ọtụtụ n'ime ha nwere isi ihe abụọ na-eji: akọrọ na mmiri. Ya mmepụta - nnọọ oké ọnụ na ume-kpụ ọkụ n'ọnụ usoro. The na-akpọ sludge ke akpasarade ụdị na-kwajuru n'ime a pụrụ iche oven, na mgbe ahụ sintering na clinker. N'oge n'ichepụta usoro ọkụ ahụ na-nọgidere na-agba gburugburu, nke mere na clinker ọ bụ uniformly mbuaha. Nke a na-enye ohere maka ihe homogeneous ngwakọta na evenly gbazee.

The cement mejupụtara gụnyere ígwè oxide. Ọ nwere nnọọ nnukwu mmetụta na n'ozuzu àgwà nke dapụtara cement ngwakọta. Ciment kasị mma - na ígwè oxide ọdịnaya nke banyere 10%. N'oge a ruru oxides nwere kasị mma utịp ke guzobere mineral. Otú ọ dị, ihe niile dị mkpa ụfọdụ, n'ihi ya, dịkwuo ego nke ígwè oxide na simenti na-ebelata na ya n'ozuzu ya mma.
The kacha allowable ọnụego a na-ewere 25% nke ígwè oxide. Dị ka ị maara, ciment na-eji ndị na-ewu ma ọ bụ na e guzobere okpomọkụ na-eguzogide ụlọ na owuwu. Na nke a, ọnụnọ nke ígwè oxides bụ adịghị anakwere. Ke adianade do, ego nke ígwè nwere a kpọmkwem mmetụta na simenti agba: na-aga n'ihu na ọ bụ, ndị na-erughị pasent nke nwekwara. Gray ciment, na iche, nwere na ya Ọdịdị kasị elu ọdịnaya nke ígwè oxides.

Ọ bụrụ na n'ihu ebukọtala na chemical mejupụtara nke ciment, ọ bụ ike ịchọpụta na ọ na alumina. Onye kasị ukwuu ego nke alumina ẹdude ke ciment mejupụtara, na-enye ya Njirimara nke okpomọkụ na-eguzogide. Qualitatively, ciment ọdịnaya nke umi bụ banyere 60%.

Tụkwasị na nke a oxides, a cement mejupụtara agụnye calcium oxides, sịlịkọn, magnesium. Cement emepụta na-ifịk ifịk na-alụ ọgụ ka ha na ngwaahịa adịghị nwere a chromium oxide, nke bụ ifịk metal na-abịa n'ime undesired chemical Jeremaya mere.

Dabere na mejupụtara nke ciment, ọ na-ekewa ụdị enwe dị iche iche anụ ahụ Njirimara: gipsoshlakovy, ngwa ngwa ọnọdụ, ash, alumina, gipsoglinozemisty na waterproof.

The cement mejupụtara ka mma ya àgwà tinye dị iche iche n'ọrụ ịnweta nwekwara. Ha na-wuru ma ọ bụ eke si malite. Nwekwara ciment na-enye ya dị iche iche Njirimara: ya mma workability na-abawanye ntụgharị, melite scalability, belata shrinkage, plasticity na-agbanwe ihe njupụta. Ọzọkwa, na mgbakwunye na nke a bekee eme anwụ ngwa ngwa na ike nke ciment slurries.

Nwekwara ciment na-abụghị nanị na-eji iji meziwanye ụfọdụ nke ya kpọmkwem ahụ Njirimara, ma na-agbanwe agbanwe, na ihe atụ, na agba. N'ihi na ndị a na nzube, i nwere ike iji a mgbe nile agba.
