Lebenkii wax gubi jiray ee foornada warshadaha
Faa’iidooyinka badeecada: iska caabin heerkulka sare, iska caabinta nabaad guurka, xoog dhisme sare, daacadnimo wanaagsan, xasilooni kaamerada kuleylka leh, nolol adeeg dheer, iwm.
Codsiga badeecada: Gubayaasha weelka warshadaha sida dhisidda dhoobada iyo dhoobada maalin walba la isticmaalo. Isbeddellada heerkulka ee soo noqnoqda, shuruudaha xoogga sare, xirashada iska caabbinta,
sharaxaadda alaabta
Gubtaha ayaa sidoo kale loogu yeeraa gubiye, kaas oo ah aaladda gubanaysa dekadda gaaska ee ku jirta shooladda shidaalka ee warshadaha, waxaana loo fahmi karaa inay tahay “dab -damis”. Caadi ahaan waxaa loola jeedaa qaybta jirka ee aaladda gubashada, oo leh marin shidaal, marin hawo iyo dalool buufin, kaas oo ka ciyaara doorka qaybinta shidaalka iyo hawo taageerta oo ku buufisa si gaar ah si loo gubo. Waxaa jira laba hab oo wax -soo -saarka lebenka gubashada ee sida caadiga ah loo isticmaalo, dhagaxa lebenka ee jaban iyo horudhaca isku -dhafan ee kabka ah. Lebenkii wax gubayay ee hadda la isticmaalayo asal ahaan waxaa laga sameeyay qallafsan oo dabacsan oo hal mar la gariiriyey iyada oo loo marayo caaryar gaar ah.
Shaqooyinka lebenkii wax gubayay ee dameerkii waa:
1. Ku shub shidaalka ku jira lebenka gubanaaya heerkulka dabka si ay u sahlanaato in si fudud loo shido loona gubo;
2. Ku ilaali heerkulka sare ee lebenka wax guba si loo xasiliyo geedi -socodka gubashada oo looga fogaado garaaca ama joojinta gubashada;
3. Abaabul qaabka ololka si loo buuxiyo shuruudaha hannaanka kululaynta;
4. In la sii qaso shidaalka iyo hawada.
Marka loo eego agabyo kala duwan, waxay u qaybsan tahay afar qaybood: corundum, aluminium sare, carbide silikoon, iyo mullite. Sida waafaqsan shuruudaha, agabyo kala duwan ayaa loo xushay wadar ahaan iyo budo, waxaana lagu daraa waxyaalo isku jira. Aluminium fosfate -ka waxaa loo adeegsadaa sidii xayndaab. Gariirka waa la sameeyay oo waa la dubay. Noqo ,
