9. Ịmepụta ngwa agha plastering ngwa agha na-ejigide mmiri dị elu na-eme ka ciment ahụ nwee mmiri zuru oke, na-abawanye ike nkekọ, ma n'otu oge ahụ n'ụzọ kwesịrị ekwesị na-abawanye ike ike na nke siri ike, nke na-eme ka mmetụta ụlọ na arụ ọrụ dịkwuo mma.
10. Tile nrapado High mmiri njide anaghị achọ tupu impregnation ma ọ bụ wetting nke taịl nile na isi n'ígwé, nke budata mma nkekọ ike, ogologo ewu oge nke slurry, ezi na edo ewu, adaba ewu, na magburu onwe mgbochi Mbugharị.
Usoro mgbasa
1. Were mmiri ọkụ dị mkpa achọrọ, tinye ya n'ime akpa ma kpoo ya n'elu 85 Celsius C, ma jiri nwayọọ nwayọọ tinye ngwaahịa a n'okpuru nwayọọ nwayọọ. Cellulose na-ese n'elu mmiri na mbụ, ma a na-eji nwayọọ nwayọọ gbasaa ka ọ ghọọ otu slurry. Mee ka ngwọta ahụ dị jụụ na edemede.
2. Ma ọ bụ kpoo 1/3 ma ọ bụ 2/3 nke mmiri ọkụ na 85-ma ọ bụ karịa, tinye cellulose iji nweta mmiri ọkụ na-ekpo ọkụ, tinyezie ihe fọdụrụ nke mmiri oyi, na-akpali akpali, ma mee ka ngwakọta ahụ dị jụụ.
