1. notes for use 严禁烟火
环氧树脂类, 分类为危险品, 为容易燃烧之材料。因此, 材料之保管, 施工时, 禁止在现场附近抽烟、焊接作业、使用焚烧等烟火。
Epoxy resins are classified as dangerous goods and are easily combustible materials. Therefore, it is forbidden to smoke, weld or burn fireworks near the site during the storage and construction of materials.
In case of accident, fire extinguishers (powder, halogen, foam and other suitable forms) should be provided.
使用含有有机溶剂材料时, 因有着火、爆炸之虞, 应使用防御型搅拌器。
When using organic solvent materials, fire blitches and explosions should be used.
Take air change
因有机溶剂挥发而作业室内充满有机溶剂时, 因有爆炸或缺氧、急性有机溶剂中毒之危险性。应使用换气设备, 采取充分之换气。
When the operating room is filled with organic solvents due to volatilization of organic solvents, there is a risk of explosion or anoxia, and acute organic solvent poisoning. Ventilation equipment should be used to take full ventilation.
如因出入口小, 无法充分换气时, 应使用有机剂用防毒面罩或视情况使用送气面罩或自给式呼吸器。
If the inlet and outlet is too small to be fully ventilated, use an organic gas mask or, as appropriate, a breathing mask or a self-contained respirator.
Use protective appliances
环氧树脂类或洗净剂(有机溶剂)接触到皮肤, 会发生变红或斑疹等皮肤炎, 因此, 使用材料时, 应戴保护手套, 穿保护衣。
Epoxy resin or detergent (organic solvent) contact with the skin, will occur red or rash and other dermatitis, therefore, when using materials, should wear protective gloves, wear protective clothing.
作业前, 手如擦护肤霜, 因材料不会直接侵入皮肤, 也有效果。
Before your homework, your hands will be rubbed with skin cream, because the material will not directly invade the skin, but it will also be effective.
如要洗净附着在皮肤的材料, 不要使用溶剂, 以肥皂或洗剂冲洗。
If you want to wash the materials that are attached to the skin, do not use solvents, rinse with soap or lotion.
若因接触而发生皮肤炎, 可用食用醋或5%醋酸稀释液浸15~30分钟, 可与硬化剂中的胺中和。
If skin inflammation occurs due to contact, soak in vinegar or 5% acetic acid diluent for 15-30 minutes and neutralize with amine in the sclerosing agent.
进入眼睛时,立即以洗眼装置用水或0 . 9%无菌食盐水洗眼至少15分钟,之后再看眼科医生。
When entering the eye, wash the eye immediately with water or 0.9% sterile saline for at least 15 minutes, then see an ophthalmologist.
Storage is not in the sun, rain, snow house.
Do not keep it around the place where it will be heated or around the fireworks.
2. prime condition
Plain concrete (mortar)
Plain concrete (plaster) is smooth with metal trowel.
混凝土打完后养护四周以上, 灰泥则二周以上, 并且使之充分干燥。
After curing, the concrete will be maintained for more than two weeks, and the mortar will be sufficiently dry.
For uphill grouting, use steel mould or three splint.
The honeycomb holes filled with concrete are filled with mortar.
The slope of drainage is completed by concrete or mortar.
容易自素地受水份影响之处(环氧地坪、槽内等), 应做充分之防水处理, 同时, 内部防水以防水灰泥时, 避免使用金属肥皂系防水剂。
Sufficient waterproofing should be done in areas easily affected by moisture (floor, trough, etc.). At the same time, metal soap waterproofing agent should be avoided when waterproofing plaster inside.
The surface of the surface should be smooth as far as possible.
Use dedicated PRIMER.
3. prime processing
The surface mud and dirt are removed by using the floor grinder.
Remove dust and dust.
Use electric grinding machine, high speed sand Blanding machine (SAND BLAST) and so on to completely remove surface fouling, grease stain and rust.
The maintenance between the projects shall be carried out according to the smearing intervals of the specifications. (slightly changed due to construction temperature)
The maintenance time after completion is more than three days. (benchmark 20 C)
During maintenance, do not let water or dust enter.
5. precautions for use after construction
If there is too much moisture in plain concrete, the floor may be expanded or peeled off.
If the floor is towed and fallen into metal or stone hard material, the floor material will be damaged.
If there is water, oil and dust on the floor, it is easy to slip.
Because of the use of drugs or concentration, the floor has the possibility of discoloration.
Quality inspection standards and requirements for floor paint Engineering:
In order to ensure that the floor construction can achieve the best results. Choosing the right materials, construction specifications, the rational use of materials is the basic problem, but we need to pay attention to the humanized service and management, scientific and rational design of the construction plan of the floor, professional construction team, strict quality supervision and so on.
Some large floor companies generally choose coating quality testing equipment for product quality testing and coating quality testing, but the price of the instrument is too high, some small enterprises can not afford to buy, so, some floor quality testing standards and requirements arise spontaneously.
For example, it is required that the flatness of the ground should be within the range of 2M and the difference is less than 2mm and the water content is less than 6%. Adhesion of coating is the most important test item for floor coating. The thickness of coatings is less than 500 micron, and the method of scratching is adopted (scratching method: cutting the coatings with cutters until the substrate forms scratches of different shapes, then using adhesive tape to adhere to the coatings and tear them apart to see the peeling off of the coatings, and then rating the adhesion of the coatings): the distance between the blades is 1 mm, the thickness is less than 60 micron; the distance between the blades is 2 mm, the thickness is 2 mm. At 60~120 m, the blade spacing is 3mm, and the thickness is more than 121 m.
A. if the coating ground is at the bottom, because the water table is relatively high, waterproofing should be done well.
B. If you want to use fine stone concrete to find normal, the strength is higher than C20, and the thickness should be less than 30mm.
C. Resin mortar or polymer cement mortar can be used instead of fine aggregate concrete for leveling in construction projects.
Comments: Use of epoxy resin floor, production workshop, workshop, chemical industry, machine room, warehouse, laboratory, ward, operating room, pharmaceutical, underground parking garage, bioengineering workshop, dust-free purification room, electronic components production area, semiconductor workshop, SMT, special workshop, etc. It has the function of protecting and beautifying the environment.
