Polishing millgranite kinds and technology

Polishing millgranite is good or bad, directly related to product luster, polishing is product last procedure, is also the most critical, and polishing technology is more complex, it includes the physical chemistry, particle grinding principle, polishing millgranite concavo-convex fill principle, such as plastic variation principle, therefore, in accordance with the above principle, talk about the make a recipe, polishing millgranite mainly divided into 4 kinds of color of polishing millgranite.

Firstly, deep hole type polishing millgranite, green polishing millgranite, main raw materials are: not saturated colophony (colorless), chrome oxide green (Cr2. O3) ordinary alumina (AL2O3), salt (NaCL), will the above materials weighing in proportion, stir well, people marble, the room temperature, then after 80 placed 24h ℃ temperature 3h, which plays to the grinding, polishing for AL2O3, Cr2. O3, filling effect for NaCL, the depth of the hole, namely into solutions for fracture-vuggy millgranite, hole distribution uniformly, reducing friction and lubrication to board.

Secondly, white polishing millgranite, main raw materials are: unsaturated resin, white jade (W1.0 ~ W1.5 AL2O3), alumina, salt (NaCL), according to the proportion must weigh, stir well, into the mold, the room temperature, then after 80 placed 24h ℃ temperature 3h, which plays polishing can is white jade, alumina.

Thirdly, black polishing millgranite, main raw materials are: unsaturated resin, white jade (W1.0 ~ W1.5 AL2O3), bits of alumina, carbon black, salt (NaCL), according to the proportion must weigh, stir well, into the mold, the room temperature, then after 80 placed 24h ℃ temperature 3h can.

Fourth, red polishing millgranite, main raw materials are: phenolic resin (phenol C6H5OH, formaldehyde laq NH4OH), or ammonia by red sage root and into, also can buy finished phenolic resin and six times methyl four amine, camphor, white jade W1.0 ~ W1.5, ordinary alumina, press the certain proportion, and weighing in on the phenolic resin WenHua loose, be like inside the iron pot for the next six times phenolic resin and methyl four amine, camphor respectively in mix into iron pot for the mold, and. Note: six times the amount of methyl four amine, polishing millgranite is hard, conversely, soft, general control in between 20 to 50, according to the product hardness to adjust polishing millgranite hardness. Camphor is mainly used for foam, the heat treatment temperature to 150 ℃, and can, in constant temperature 3h, resin heating process, forming a porous shape expansion of rigid porous millgranite, also called foam type millgranite, this kind of polishing millgranite durable, have flexibility.

Generally speaking, red to China red, polishing millgranite of red, maple leaf red (India G562) tianshan red (xinjiang) polishing effect.

Green polishing millgranite on seafloor, butterfly green, G623, etc polishing effect.

White American white linen of polishing millgranite, pearl white (jiangxi), ice jade and so on polishing effect.

Black polishing millgranite of shanxi black, FuDing black (G684), Mongolia black, South Africa dark polishing effect.

Above the polishing millgranite also applies to the marble polishing.

P;For products processing pore, gap, stone many polishing millgranite color can be inhaled product, therefore, must be the same color accordingly.
