Other types of curing agent are some toxicity, but the extent of a different, but basically are low toxicity. Where is the organic products, how can the toxicity of no Yeah, after curing epoxy glue no toxicity, it can be said that toxicity will not be higher than other plastic products Therefore, the epoxy resin sheet in daily life, is classified as the actual non-toxic products.

Q:Novice: stainless steel plate calculation and weighing what is the meaning? more specific
Stainless steel plate calculation and weighing the meaning of stainless steel through the length of the width and wall thickness using the formula to calculate the weight of stainless steel. The pounds are rated directly to the scales that weigh the stainless steel. Stainless steel can be used as a reference. The actual delivery is subject to weight.
In fact, it should be said that the price of pounds than the expensive calculation
Because the weight of the calculation will be heavier than the actual weight.
Probably the actual:
Attached to the formula:
Stainless steel square tube calculation formula: (length + width -2 times wall thickness) * wall thickness * 0.0158 = kg / m
Where the length, width, respectively, refers to the long side of the square tube and short side, the unit is mm.
Stainless steel tube calculation formula: (diameter - wall thickness) × wall thickness × 0.02491 = kg / m
The unit is in millimeters.
The above weight is for 304 stainless steel. Can be used as a reference. The actual delivery is subject to weight.
Q:The advantages and disadvantages of the plate frame, what brand is better?
Material: high-tech plastic memory sheet manufacturing.
Design: tailored for the majority of fashion and the pursuit of quality students.
Features: simple and neat design style, the overall performance of a stable one
Face, using the right color process. Emphasis on mirror legs
On the three-dimensional changes.
Accessories: mirror feet and feet perfect fusion, like totally natural, the lens shape is very personalized.
Performance characteristics: a certain degree of flexibility, when a little hard to bend or tighten after relaxation, shape memory sheet will be restored.

Q:Daren detailed explanation VCM color plate and PCM color plate difference, for the refrigerator panel
VCM board for the film, PCM for the color coated board, the general VCM board with galvanized substrate, covered with color or pattern film, the surface of such a plate is very smooth, the surface color effect is PCM can not be achieved, but the price More expensive, generally used in the refrigerator panel, or high-end wine cabinet side panels, set-top box shell, product use for the membrane requirements have a relatively high demand. PCM is a color pre-coated sheet, the surface for home appliances environmental protection paint, the price is relatively cheap compared to PCM, generally used in the refrigerator side panels, this plate is not suitable for high-grade refrigerator panel, due to the flatness of the plate than VCM difference and color The effect is single, so the main use of the side panels.

This ensures that the production of "starting line" to reduce the formaldehyde content. The quality of formaldehyde is less than or equal to 1.5mg / L, and the formaldehyde content of E1 grade (national mandatory standard) is less than or equal to 1.5mg / L
