一：The raw material
1, ingredients: according to the production of breed of design and color, the prepared raw materials (quartz sand, resin, coupling agent and curing agent, glass (white glass, mirror glass), toner, titanium dioxide) according to the formula ratio of mixing.
2, mixing: first in proportion to allocate the good resin, coupling agent and curing agent and pigment mixed within the special mixing barrel stirring for 2 minutes. Will say good quartz sand at the same time, a small amount of glass into automatic mixing with machines, adding resin, curing agent and pigment, mixture to stir with jun, takes about 7 minutes.
3, die bottom paper: in the prepared mold bedding layer at the bottom of the same specifications of the kraft paper, is used for curing after between quartz and die out easily. We are the biggest specifications template specifications is ? 1.65 meters long
5, pressing: cloth after completion of the automatic production line to the press, for 120 seconds vacuum operation, completed before the second pressurized pumping air into vacuum state, the secondary pressure time in about 25 seconds. Then shock pressure, pressure vibration time of about 200 seconds. Vacuum and pressure, of course, the time will be varies according to specifications, thickness of plate..
6, heat curing, after finished the vacuum pressure of quartz, transmitted by automatic production line to heat curing, heat curing, curing time, generally takes 40 ~ 60 minutes, curing temperature at 80 ~ 110 degrees, 1 sheet production line at the same time can be heat curing 16 slices.
7, demoulding: in accordance with the provisions after heat curing time and temperature, the automatic production line to demoulding
三：Polishing, nano fouling resistance
8, computer: natural quartz blank plate after cooling, by rail to the polishing workshop, the workshop line keep to flap machine, again by machine put big board on the leveling line.
9, is: will the level of quartz in the single side shave is flat, we commonly known as "positive", a large plate leveling time will probably about 13 ~ 15 minutes.
10 and reverse blowing: blow after the completion of the quartz writing by automatic production line of the big board turnover after inversion, to the bottom of the leveling.
11, positive, both sides will have big quartz plate leveling by the automatic production line to the polishing line, use from coarse to fine polishing head for positive polishing, polishing a large board about using 13 ~ 15 minutes.
12, nano fouling resistance: independent research and development of domestic advanced nano anti-pollution equipment, ?
13, classification: polishing process of quartz, after the completion of the automatic production line to the location of the point level, by artificial visual grading, our company's current products are mainly divided into class A plate (master plate), B (defects, such as surface with impurities, needle, porosity, such as color, can use normally after cutting or repair), waste board (can't use, scrap board).
14, the paster: grade, grade A plate of quartz, we will be labeled as positive surface protective film, have the effect of surface protection.
15, cutting: according to the requirement of the customer orders, quartz, cut into various specifications.
16, packing: our company use products at present most packaging is wooden, in addition to the customer special requirements, regular wooden weight not more than 3 ?
