The polishing principle of stone material product

0) , alumina (Al2O3) , oxalic acid (COOH2) . Polishing holystone has two kinds commonly: Colophony polish piece; Colophony casts CD. The polish of the product: Put polishing holystone on the product that is processed, with mechanical equipment rapid movement is reached " dry polish, wet polish " will achieve polishing result, product surface can appear very strong reflex, this is the glossiness that says normally. The principle of polishing basically mirrors in 2 respects: Atomic and abrade principle; Physico-chemical principle. 1, atomic and abrade: Arrive by kibble when abrasive grain when kibble, polish, abrasive is in the trace of grinding of stone material surface by thick to fine the mark that reachs to see without naked eye again, the surface appears smooth, level off, exquisite, when deepness amounts to 110 micron, by burnish of face of treatment face occurrence lens, glorious takes a person, colour and lustre is bright-coloured. Atomic and abrade comprise by the following working procedure: ① kibble: The requirement grinds a penetration of a cutting tool the quantity is deep, grinding efficiency is tall, the grain of grinding is thick, grind the appearance that give coarser, main and cleared product leaves some curiuming in advanced course working procedure a trace and the flatness the product, modelling face grinding reachs the designated position; ② half fine grind: Keep clear of kibble trace, form new fine lines, product treatment is face level off, suitable slip; ③ is fine grind: Fine the product figure after grinding, grain, color already was shown clearly come, the surface is exquisite, slick, begin to have faint glossiness; ④ essence grinds: Process the product after, without the trace that naked eye is aware of. The surface is slicker and slicker, glossiness makes an appointment with 40~50 to spend the left and right sides; ⑤ polish: The surface is like lens brightly, have certain lens face glossiness (85 degrees of above) . 2, physico-chemical principle: The process of polishing has 2, namely " dry polish and wet polish " , polishing holystone is in " dried food with wet " between send biology to manage when stone material product chemistry, dry polish is in stone material surface temperature lifts make moisture evaporates, bring about polishing holystone chroma to increase, achieve aggrandizement result thereby, product glossiness began to achieve good demand, glossiness amounts to 85 degrees of above or taller. Polishing holystone is being machined product upcast is smooth, after waiting for polishing product to warm a hand, add board area water to measure water, drop in temperature with rising action, do not allow to add water continuously or add water in great quantities, otherwise, the lubricant action of water will make polishing short of ideal the effect, also cannot use dry polish entirely, exorbitant temperature will be burned-out board face, and can make board face appears crackle. Generally speaking, after product essence is ground, the glossiness of the product is controlled in 40~50, and the glossiness above the short of after energy of some stone timber is ground, if Shanxi is black, black peace of Jin Sha, collect is black wait, only 20~30 spends the glossiness after essence of this kind of product is ground between, explain insufficient one side with the atomic and abrade principle in front, this kind of product is in polishing " dry with wet " , of temperature elevatory, in dropping in temperature, aggrandizement polish process, produce physico-chemical reaction, the product is in through " dry polish, wet polish " in, glossiness rises stage by stage, glossiness amounts to 85 degrees of above CNC Milling
