Q:How can the knife switch, glass plate and rubber sheet be distinguished?

The majority of users choose rubber board, it is not required for the environment, and the insulation performance is more stable. And generally consider cost-effective users choose glass plate more.

Q:How do electrophoresis plates do?

10 L DNA and 2 l sample volume bromophenol blue indicator sample buffer. The mixed sample buffer can not only improve the density of the sample, the sample is evenly sink to the sample hole, also can make samples with color, easy to sample and estimate and judge the position of electrophoresis electrophoresis time;8 use micro pipette to add sample carefully to sample hole, record sample order;9, cover the electrophoresis tank, turn on the power switch, the maximum voltage is not more than 5V/cm (100 ~ 150V constant voltage electrophoresis), so that DNA moves from the negative electrode to the positive electrode;Depending on the specific requirements of the 10 time with the electrophoresis experiment. Electrophoresis generally takes 1 to 3 hours. After electrophoresis power off, wearing disposable plastic gloves as far as possible to remove gel electrophoresis buffer with all stem, observed in the transmitted UV light of 254nm wavelength.

Q:What is the difference between plywood and veneer?

In fact, the two are related and different. A multilayer structure is identical with the wood plywood, the core layer which is special for sheet of plywood (high quality), but the surface and the back side is used by painting (surface species are generally relatively rare species). Second, in multi-layer solid wood in the precision, appearance quality, surface treatment of the more stringent requirements than plywood in general, plywood manufacturing cost per square meter is 10%-20% multi-layer solid wood flooring manufacturing cost.

Q:Please master, simple and easy to tell me what is: plywood, composite board, the kind of wood powder pressed into what the board? What are their characteristics, please?

The composite board is bonded with several boards, including plywood + MDF, plywood + decorative panel, MDF + melamine board, MDF + MDF and so on

Q:Excuse me: is there a rubber board in the building material market that can replace glass instead of glass?

PC sun board (also known as polycarbonate hollow board, glass Caprone board, PC monolayer or multilayer hollow board) is a high performance engineering plastics, polycarbonate (PC) resin processing, with high transparency, light weight, shock resistance, sound insulation, heat insulation, flame retardant, anti aging, etc., but not acid no, alkali, is a high-tech, comprehensive very excellent performance, energy-saving and environment-friendly plastic sheet, plastic building material widely used in the world, there are other building decoration materials (such as glass, organic glass) incomparable advantages, have "broken glass". Widely used in greenhouse / industrial plants, decoration, advertising signs, parking shed, residential lighting, commercial lighting channel poncho backdrop, exhibition lighting, stadium, swimming pool, warehouse roof, commercial factory, stadium lighting ceiling and sunshade canopy, agricultural greenhouses, aquaculture and flower greenhouses, and telephone booths, kiosks the station, and other public facilities, highway noise, advertising decoration field.

Toughness: the toughness of bamboo plywood is better;Number of times: ordinary bamboo plywood used 8 times, wooden template in 6 times;Habits: more wood templates in the south, and more bamboo plywood in the north;

Q:What is a high pressure rubber sheet?

Manufacture of non-polar rubber with excellent insulating properties, such as NR, SBR and IIR. A mesa or flooring insulating material used in power distribution and other work situations.

Q:The difference between laminated lumber and plywood

LVL (Laminated Veneer, Lumber, LVL) is made of thick veneer along the longitudinal direction of laminated blank, hot pressing and cutting into materials; plywood is made of wood into veneer or by wood sliced veneer, with adhesive glued into three layers or multilayer plate material, usually with odd veneer, and the fiber direction perpendicular to the adjacent layers of veneer glued together.

Q:About up to the use of modified rubber sheet!

The price is almost the same, there is nothing particularly worthy of recommendation. Play mode, Qu Feng Tang, Shangzhi toys, roaming model, Qu Feng Tang, the KING model, they generally have a sheet, you see what love style!
