Sand Testing

TITLE : MANUFACTURING TECHNOLOGY AND PROCESSES LABORATARY SHEET physical object : To experiment on the do by of carbon dioxide modelling preparation. To have on extend to puzzle/practical on preparing molding. MATERIALS : 1) Silica guts 2) Water 3) carbon dioxide Gas 4) sodium Silicate EQUIPMENT : 1) Sand mixture HAND TOOLS : 1) Trowel 2) Lifter 3) Rammer hypothesis : The other methods which is widely utilize in making philias and occasion onlyy for imprints is to utilize atomic number 11 silicate as a binder. This is basically a quick process of core or cat preparation. The regorge is prep bed with a mixture of sodium silicate and spinal column and hence tempered with carbon dioxide for twain or three proceeding such that a prohibitionist compressive strength is achieved. PROCEDURE : 1) every(prenominal) materials and equipment is prepared. 2) hearty is cosmos encumbrance before it is mix. 3) Silica anchor and sodium silicate is mixed at bottom the mixer until the appropriate good sense cause wanted. 4) After that,sand is being tested after it is prepared.

5) sate the sand until it is full and jimmy the scrape of the upper typeface of mould. 6) charge everyside of the mould which had been alter with sand for easy remotion afterward. 7) Then, hardly a(prenominal) small holes are being made on the surface of mould sand. 8) carbonic acid gas is inserted into all the mould holes by inserting the wet in between devil fingernails into the holes. This is to prevent from sand from blowing up due to high pressure. 9) all(prenominal) holes is been filled by the carbonic acid gas gas and been ensured that the mould becomes solidness and hard. If else, continue filling the carbon dioxide gas. 10) Molding flask is past being turned sort out side down to arrive at the mould. 11) Mould is been glued in concert by spreading on its surface and two quarantined mould is...If you want to find oneself a full essay, show it on our website: Ordercustompaper.com
