Onebusaway composition for wood processing
(57) Abstract:Usage: the invention relates to compositions for wood protection against fire and can be used in the woodworking industry, the construction industry in the processing of wood products, as well as in any other industry that uses wood. The essence of the invention: invention allows to obtain a solution having a high fire - and bio-protective properties, with the possibility of decorative painting wood, safe for work, in addition to cooking disposed of waste printed circuit boards. The composition includes the following components, wt.%: complexing polymer amine 3,0-6,0, zinc salts (sulfate, chloride, nitrate) of 0.4-0.5, iron sulfate 5,0-6,0, sulfosalicylic acid of 0.1-0.15, alkaline provide the Etchant printed circuit boards (contains 20-22 salts of copper and 10-17 ammonium chloride) 4,0-5,0, ammonia water 3,0-5,0, water - the rest. 1 C.p. f-crystals, 3 tables. The invention relates to compositions for wood protection against fire and decay and can be used in the woodworking industry, the construction industry in the processing of wood products, as well as in any other industry, Ilfat copper 7-25, ammonium chloride 50-86 (ed.St. USSR N 810494, MKI 27 TO 3/32, N 9, 1981). This composition contains a substance related to the 4th class of danger: chrome connection that makes it toxic and hazardous to humans and the environment when working with him. The composition has an acidic environment from an environmental point of view less acceptable than slightly alkaline or neutral composition.Known fire - and bioprotective drug, comprising, by weight. the copper sulfate 5-25, sodium bichromate 5-25, waste boric acid 50-90 (ed. St. USSR N 1255435, MKI 27 To 3/32, N 33, 1986). This composition contains substances belonging to the 4th class of danger: chrome, boric acid and has an acid medium. All of this increases the toxicity of the drug for people and the environment, environmental hazard of the drug dramatically reduces the scope of its application.Closest to the proposed composition is heat - and bioprotectant composition containing, by weight. the copper sulfate 10-70, ammonium chloride 16-45, desativada sodium tetraborate or pentaborate sodium, potassium or ammonium 10-45 (ed. St. USSR N 1017500, MKI 27 To 3/32, N 18, 1983). This composition is used fairly scarce salt: tetraborate, in addition, the composition is characterized by a low resistance, bio-protective ability and not the Kimi fire - and bio-protective properties, with the ability decorative painting wood, safe at work and in the preparation of the solution of waste printed pay.To achieve the above technical results of the proposed structure, including salt copper ammonium chloride, contains complexing polymer amine salt of zinc, iron sulfate in the form of soluble and partly insoluble complex compounds with polymeric amine and sulfosalicylic acid, ammonia water, and the salt of copper and ammonium chloride is added in the form of the spent alkaline of provide the Etchant for printed circuit boards, in the following ratio, wt.Complexing polymer amine 3,0-6,0
Iron sulfate 5,0-6,0
Sulfate or chloride or nitrate zinc 0,4-0,5
Sulfosalicylic acid 0,1-0,15
The spent alkaline provide the Etchant PCB containing 20-22 wt. copper duhalista 2-water, 10-17 wt. ammonium chloride and the rest is water - 4,0-5,0
Ammonia water 3,0-5,0

The composition differs from the prototype on the components used and their combination. Thus the present invention meets the criterion of "new".For the experimental verification of the properties and technical characteristics composition was prepared with 5 mixtures of ingredients (table. 1). The compositions prepared according to the following example 1.P R I m e R 1. Content, wt. 20 water dissolve 3,0 complexing polymer amine (TU 080-176-03-90) and 6.0 sulphate of iron (GOST 4148-78), then separately 5.0 water dissolve 0,4 zinc salts (zinc sulfate GOST 4174-77 or zinc chloride GOST 4529-78 or nitrate zinc GOST 5106-77) and 0.1 solfataricus acid (GOST 4478-78). Merge sequentially in the capacity of the dissolved components, add 4,0 waste of alkaline provide the Etchant containing 20-22 copper duhalista 2-water (GOST 4167-74), 10-17 ammonium chloride (GOST 2210-73), the rest is water and add 3.0 ammonia water (GOST 3760-79) and water up to 100, then stirred at room temperature.When testing three part 1, 2, 3 showed the best results (table. 2, 3).Part 4 is poorly expressed, watery color and considerable sediment, changes its appearance and color. Part 5 has all the positive characteristics, but the disadvantage is the excessive consumption of the source is am formulations in comparison with the prototype. The compositions applied to the surface of the wood with a swab or brush in 2 layers with intermediate drying in air for 0.5-1.0 hours As can be seen from the table. 2 indicators for flame retardant ability of the proposed structure is slightly higher than that of the prototype.Impregnation ratio on the absorption and impregnation ratio on depth allows to estimate the bioprotective properties of the composition (table. 3).Impregnation by the absorption coefficient is the ratio of the magnitude of the absorption solution bioprotectant composition (kg/m3) to the magnitude of the absorption solvent. Impregnation ratio on depth is the ratio of the depth of penetration of the solution bioprotectant composition to the depth of penetration of the solvent or across the grain. The results show that the indicators of fire-retardant properties of the proposed composition is somewhat higher than in the known. High impregnating the coefficients of absorption and depth indicates an increase of term wood protection offered sostava and the reduced flow of the composition during application to the surface. An additional positive feature of the proposed structure, increase its effectiveness, is nevymyvaemye sediment clogs the pores of the wood and helps keep the composition in the body of the wood, increasing its ability to absorb, to improve impregnation ratio. Vymyvaemosti composition experience by keeping the samples coated with the composition in running cold water for 1-8 hours, the Samples treated with the proposed structure and the prototype in 2 layers with intermediate drying for 0.5-1.0 hours, the Samples coated with the proposed composition, remain unchanged in prochnau water. The samples coated with the composition of the prototype, flushing occurs within 15-30 minutes So that the composition has a stability and long persistence bioprotective properties of wood in humid climatic conditions. 1.
