1、环氧树脂地板特点的基本概要（Basic features of epoxy flooring）Basic features of epoxy flooringEpoxy resin floor due to enforce the laws and regulations of the state environmental protection and energy saving, high pressure building reinforced engineering hidden materials, to force the anti-corrosion treatment, nat

2、ional standards for building structural adhesive will soon be introduced, affected by these factors, rubber demand will no solvent, high performance ultra conventional development. In 2009, the high performance epoxy structural adhesive, will continue to lead the high-end market in China adhesive ma

3、rket growth, (represented by Yanji ratio) greatly influence the final performance of waterborne epoxy floor coatings, adding can not only reduce the cost of waterborne epoxy floor coatings, shorten the surface dry time, also can improve the coating the mechanical strength, wear resistance, gloss and

4、 hiding power, reduce the volume shrinkage during curing coating, paint and give good storage stability; but adding excess will increase the viscosity of water paint, causing the surface effect of coating leveling variation, construction difficulty, poor film. Another function of the epoxy resin flo

5、or dispersing agent is pigmentation, and the particle size and density of various pigments and fillers are different. Requirements with different pigment cohesive force is weak, to show color uniformity, without causing the flooding and floating color. General should polymer, its moderate hydrophili

6、c lipophilic balance values so that it has good compatibility with the two-component system, can control the floating color effectively and can make a very good pigment dispersion stability in the system, so as to improve the storage stability of the product. Water based epoxy self leveling coatings

7、 should be selected with defoaming agents, dispersing agents, dispersing agents, rheological modifiers and levelling agents. The compatibility of the waterborne epoxy system should be considered in the concrete selection to avoid the defects such as gel and coating oil slick. Chinese Epoxy Resin Ind

8、ustry Association experts said, the role of dispersant is two times the particle surface wetting of pigment and filler, and the mechanical shearing mode from the two to the primary particle surface grinding particle adsorption, coated by negative charges repel each other, make Yan Tian material stab

9、ly suspended in the paint, keep stable state. Epoxy resin flooring market temporarily sideways, after a large early next week after the market mentality generally pessimistic to short adjustment, the recent declines in ease, for the inflection point, but the overall market decline has not yet reache

10、d the status of go downstream manufacturers expected, propylene glycol polyether, downstream manufacturers worry after receiving goods trading price down risk, the downstream market yet demand volume, cautious inquiry. As a result, the epoxy resin flooring market inflection point has not really arri

11、ved, there is still room for decline. Domestic propylene market vulnerable consolidation Thursday. In addition to the northwest region of plastic mold factory down 100 yuan / ton, the rest of the temporary stability. Propylene began to increase in Hong Kong yesterday, mainly in East China and North

12、China ports, and the prices were lower. To have the sufficient supply of domestic refineries a head-on blow pressure, the current refinery device are low load operation. And downstream propylene oxide and polypropylene powder Market Trading deserted, propylene is no good support. Although oil prices

13、 continue to rise, but the venue more cautious wait-and-see posture. Short term propylene may not rise. There is no improvement in the liquid chlorine market today, and the market for liquid chlorine is still in the doldrums. Downstream demand limit, the enterprise liquid chlorine shipment is not sm

14、ooth, liquid chlorine Market in the short term market is difficult to optimistic, still maintain the early downturn trend operation. Frequent unnecessary wear and tear. Especially for the ESL floor, keep it clean for the advantages of meticulous, beautiful appearance, special attention to avoid the

15、steel wheel traffic; not have a heavy traffic and load, contact with the ground to avoid scratches. Surface cleaning, epoxy resin floor surface cleaning method is simple, generally scrub with water. Such as the victims of cleaning stains, use cleaning agent can be also used in industrial degreasing

16、agent, detergent, then rinse with water. For fairly stubborn stains, mechanical cleaning can also be used, but do not press the ground and wear too much to affect the smoothness and shine of the ground. Floor - beautiful, in order to maintain a good surface finish and beautiful effect, do not use me

17、chanical methods to clean, you can use the mop and detergent method, and use water to remove. Because of the vast dust chamber, mainly used in the laboratory, electronic production workshop, to maintain its appearance and other good performance, usually pay attention not to chemicals especially orga

18、nic acid light fell on the ground, the ground has been polluted, to clean water immediately. For difficult cleaning chemicals, or when the ground is dyed difficult to remove, you can use a small amount of acetone quick cleaning, please pay attention to ventilation when this operation. Poor solvent b

19、ased floor paint may even emit harmful substances Months and years pass by., we went to a factory, the responsible person told us that they plant half a year ago in order to reduce the production cost, purchasing the floor paint price is quite cheap, late often exudes a pungent smell, can not comple

20、tely shut the window. Because of considering the employees body health, could not help but now not to redo. Therefore epoxy floor renovation,It is suggested that the business in the choice of floor paint, not only from cost considerations, but also to learn from the aspects of epoxy floor paint, peo

21、ple-oriented, environmental harmless floor paint materials it is understood that there are some companies in the purchase of floor paint when considering the price, in order to reduce the cost of procurement, the use of solvent based epoxy floor paint with xylene, industrial floor paint solvent cont

22、aining toluene did great harm, cause great harm and no end of trouble for the future, to human health. In fact, the so-called benzene poisoning refers to inhalation of benzene vapor or skin exposure to benzene poisoning caused by the acute, chronic. Divided into acute benzene poisoning mainly produc

23、es anesthesia the role of the central nervous system, coma and muscle twitching; high concentrations of benzene have a stimulating effect on the skin. The long-term exposure to low concentration of benzene can cause chronic benzene poisoning, appear hypoproliferative ring Oxygen floor is one of the

24、most widely used in the industrial floor in the floor, the floor construction seems simple, but in fact, it is the requirements for the construction is very high, often prone to the quality of construction in the floor when the hidden. For example, the base surface oil content, is a more difficult,

25、but also in our epoxy flooring, especially the old floor often exist problems. Here for you to introduce, if the oily ground processing. Oily ground treatment steps:1, clean the ground: before construction, the ground must be treated to remove impurities, while the old ground of machinery and equipm

26、ent to protect the work2, oil removal: in oil place by manual cleaning, or use them to clear oil was burning.3, wash: hydrochloric acid has played a major role. In addition to the oil concentration of hydrochloric acid can not be too high, 45% can be used. For heavier oil, you can wash several times

27、. Use this method to Caution! Ventilation, construction personnel if accidentally spilled hydrochloric acid, need to rinse with plenty of water4, alkali washing ground: use a kilogram of caustic soda and 20 kg of water mixture, scraping the ground surface, the purpose is to neutralize the hydrochlor

28、ic acid on the ground. However, the amount of hydrochloric acid can not be greater than the alkaline wash, because the epoxy floor acid is not alkali resistant5, grinding treatment: the use of grinding machine to ground corrosion of cement and oil stains off, and then flush the ground with plenty of

29、 water6, drying: if ventilation is better then ground generally two days to dry, for drying can be performed after the epoxy floor construction; if the weather is not good to a week, you can also use air conditioning or dehumidifier with epoxy self leveling floor commonly used three kinds of constru

30、ction methods and materials is not fixed the standard materials and construction used in Europe and the United States, Japan, South Korea and other countries are different in Chinese, these three kinds of methods are used, but due to gradually reduce the project price, multilayer (more than three) s

31、ystem because of its low material costs accounted for the mainstream in the market.One or two coat coating system:1, the selection of materials and features: primer (base oil) and solvent-free epoxy coating, self leveling quartz sand (silica); primer selected solvent free, permeability and good seal

32、ing; and this solventless epoxy self plane coating usually consists of epoxy resin, curing agent, color and additives etc., containing no or less filler, and will be in the field and mixed, also adding a certain proportion and the grain size of quartz sand (powder) with a trowel coating slurry, with

33、 serrated scraper coating, and nail roller rolling surface defoaming and help leveling.2, key points of Construction: because two forming, so this method on uneven ground do thin self repair usually need to show off and leveling on, otherwise after the construction of the smoothness of the poor; sec

34、ondly, primer must be able to ensure complete closure of the substrate pore; three is the nail roller must be used.3 main features: this method is mainly for foreign enterprises (especially the floor paint 767939) used or recommended, few construction procedures, for short duration, quality control

35、is relatively good, but the high cost of materials (mainly surface coating amount), especially on flat substrate of high ground.Two or three coat coating system:1, the selection of materials and features: compared with the two layer coating system, plus a trowelling self leveling coating, can be a m

36、aterial plus filler coating, can also be a good production of self leveling paint B is a mixture of coating material used for the best, but there is a difference between the other. The surface coating produced by good solvent free epoxy top paint and mixed directly after coating, without on-site fil

37、ler, can control the amount of surface coating in the 0.8-1.2KG/ square meters between. In addition, the painting and self leveling using two trowelling top paint method can also be classified as such (but two as a thin coating of thick coating, so two coating surface coating method is seldom used),

38、 but the top paint than the price of painting in self leveling to higher prices much.2, construction: the construction is easy, because the use of two trowelling self leveling process, greatly improve the flatness.3, the main features: this method of construction and two coating system compared to t

39、he material costs reduced, the construction quality better control, of course, the surface thickness decreased.Coating system of three or four or more layers:1, the selection of material and characteristics: compared with the two and three layer coating system, mainly used in coating a scraper scrat

40、ch process, scrape putty mortar, depending on the thickness of coating requirements to determine the number and combination of grinding and leveling the ground, such a coating material on all aspects of reducing the requirement. The surface coating produced by good solvent free epoxy top paint and m

41、ixed directly after coating, without on-site filler, can control the amount of surface coating in the 0.8-1.2KG/ square meters between.2, construction points: construction process is more, construction period is long, labor costs are higher.1, in order to achieve the perfect effect of painting, our

42、company suggested: for the yet to make the ground, our company participated in the site of the cement leveling layer leveling. Civil engineering to find the usual, when the cement early coagulation, with our company specializes in ground machinery for ground polishing. On the basis of this, the surf

43、ace effect of the epoxy coating layer will be more smooth and bright, and the service life will be improved.2, after the drying of cement layer (about 28 days), with grinding machine to ground the overall grinding treatment, so that its surface smooth, cement pores all open.3, for the cement ground

44、with oil (cooking oil, oil), first wash the surface with special lotion, scrub again and again until there is no oil.4, for the floor alkaline too big (PH8), first with special material neutralization, and then rinse with water;5, for wet ground, through water absorption. Dry hot air blowing machine

45、, lamp light, drying, burning, dry it meets the requirements of construction.6, for the old painted ground (such as emery, ground, old paint, ground), first use special machinery to eradicate old paint, and then on the bad cement, emery ground processing, while the ground hair. After such treatment,

46、 the surface of the old cement and carborundum surface is removed, and the coarse wool surface is formed, thereby enhancing the adhesion of the new coating and improving the service life of the coating floor.(1) grasp the size and quantity of the workpiece to be painted first.(2) according to the de

47、gree of corrosion and oil stain on the surface of the work piece, the basic working hours needed for the surface treatment of each workpiece are calculated.(3) according to the coating quality grade requirements, determine the total number of work hours required for the number of job putty, the numb

48、er of grinding times, and the number of sprayed lacquer layers.(4) determine what kind of drying method is used for putty, primer and finishing coat, and whether wet touch wet process is adopted (not recommended, natural drying is better), and calculate the auxiliary hours needed for drying time(5)

49、according to the size and quantity of the workpiece, determine the single operation or collective operation, master the single and small number of workpieces, the single operation and the collective operation of the different conditions of work hours. Generally large quantities of workpieces can be

50、appropriately reduced by 2%5% hours.(6) in order to build mass production in a flowshop, the work hours can be estimated according to the degree of division of labor. According to the complexity, estimate the working hours, eventually adding special temporary consumption compensation 5%8% hours, a n

51、umber of products is the total amount of work required.1, in order to achieve the perfect effect of painting, our company suggested: for the yet to make the ground, our company participated in the site of the cement leveling layer leveling. Civil engineering to find the usual, when the cement early
