Q:How dnf advanced carbon ashes?
Mall has sold, and sometimes activities, and now there is no
Q:Can carbon in barbecue cause cancer? Can carbonated food cause cancer?
It will be。WHO published 3 years of research results, said barbecue foods produce carcinogenic substances are toxic, "eat barbecue, equivalent to smoking."". A US research center report even said eating a roast chicken leg is equivalent to the toxicity of 60 cigarettes; women who eat barbecue are 2 times more likely to develop breast cancer than other women.
Q:How do you remove the carbon stains on your clothes?
1, first pour alcohol on clothes, fountain pen scratches, every scratch should be evenly covered with alcohol, alcohol should be used at a concentration of not less than 75% of the medical alcohol.2, pour the clothes down, put this side of the alcohol up, try not to touch other surfaces of the clothes, otherwise, the color of the pen or ballpoint pen may be stained with other parts of the clothes.3, with ordinary washbasin, ready most of the basin of water, and then will be full of two bottles of bleach water poured in the water, pay attention to must be full two bottle cap.4, take a stir, and then add a little washing powder, this amount can be mastered.5, after a little mixing, so that washing powder can be fully dissolved in water. Well, now soak your clothes in water for twenty minutes.
Q:What type of carbon copy sheet can be printed on? How many copies?
Generally 100 pages, such as:One copy of the two couplet is 50 copies.One copy of the triad is 33 copies.One copy of the quadruple is 25 copies.This is a five of the 20.
Q:What should be done to deal with leakage of carbon monoxide from the plant?
The container should be cooled by heat in time. The harm to health, carbon monoxide and hemoglobin binding capacity than oxygen 200 times larger, after inhalation, in the blood and hemoglobin binding, interference blood carrying oxygen capacity, resulting in tissue hypoxia. The skin starts to become gray, and the skin and mucous membranes are red. Severe damage to brain cells can also cause secondary diseases, light damage to the heart, and damage to pyramidal or extrapyramidal systems, including the basal ganglia. Acute poisoning: mild poisoning are headache, dizziness, lethargy, tinnitus, palpitation, nausea, vomiting, weakness, abdominal pain, weakness and other symptoms; moderate poisoning in addition to the above symptoms, and complexion, lips cherry red, rapid pulse, irritability, instability of gait, fuzzy consciousness, coma patients remain unconscious;, miosis, muscle tension increased, frequent convulsions, incontinence, depth of poisoning due to respiratory paralysis and death. Chronic effects: the main manifestation of long-term inhalation of a certain amount of carbon monoxide, fatigue, irritability, indigestion and so on, can cause damage to the nervous and cardiovascular system. The compressed gas storage requirements in bottles, should be stored in a cool, ventilated warehouse, storage temperature should not exceed 300C; keep away from heat, avoid direct sunlight; and oxygen, compressed air, oxidant and stored separately; avoid mixed mixed transport. The lighting, ventilation and other facilities in the storage room shall be explosion-proof, and the switch is located outside the warehouse. Equipped with appropriate varieties and corresponding quantity of fire-fighting equipment.
Q:Where are carbon fiber sheets and carbon fiber sheets used?
Carbon fiber and carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg, carbon fiber cloth, carbon cloth, carbon fiber fabric, carbon fiber, carbon fiber sheet (prepreg) etc.. Carbon fiber reinforced fabric is one kind of unidirectional carbon fiber reinforced product, usually made of 12K carbon fiber silk fabric. To reinforce the structure of the tensile and shear strength and seismic carbon fiber cloth, the supporting material and impregnated together using a carbon fiber composite material, carbon fiber cloth sheet excellent performance can be enhanced to form a complete system, suitable for processing the building load increasing, the engineering function change, material aging, concrete strength grade is lower than reinforcement design, structure crack treatment, environment protection and repair service component.Carbon fiber board 1) Aerospace: airframe, rudder, rocket engine shell, missile diffuser, solar panel, etc.;2) sports equipment: auto parts, motorcycle parts, fishing rods, baseball bats, skis, boats, badminton rackets and so on;3) industry: engine parts, concrete structures, reinforced materials, fan blades, transmission shaft, and electrical components and so on;4) fire: suitable for army, fire fighting, steel mills and other special high-grade fireproof clothing production.Fire rating: Class A - non flammable, standard GB8624-2006, German standard DIN4102, A1 classCivil buildings, bridges, tunnels, earthquake, reinforced concrete structure, reinforcing material for reinforcement structure, tensile shear and seismic carbon fiber cloth, the use of common materials and supporting adhesive, constitute a complete performance excellence with carbon fiber cloth material reinforcing system. The system is suitable for beams, columns, slabs, tunnels, circles, arcs, etc..
Q:Carbon fiber three tripod, buy what brand good?
In fact, only three foot two brands: brand and other brands of Gitzo
Q:What are the specifications of carbon fiber cloth?
Carbon fiber and carbon fiber cloth, carbon fiber cloth, carbon fiber woven cloth, carbon fiber prepreg, carbon fiber cloth, carbon cloth, carbon fiber fabric, carbon fiber, carbon fiber sheet (prepreg) etc.. Carbon fiber reinforced fabric is one kind of unidirectional carbon fiber reinforced product, usually made of 12K carbon fiber silk fabric.Available in two thicknesses: 0.111mm (200g) and 0.167mm (300g). Multiple widths: special widths required for 100mm, 150mm, 200mm, 300mm, 500mm, and other projects. With the continuous development of carbon fiber cloth industry, more and more industries and enterprises have applied to carbon fiber cloth, and some departments have entered the carbon fiber cloth industry and developed.To reinforce the structure of the tensile and shear strength and seismic carbon fiber cloth, the supporting material and impregnated together using a carbon fiber composite material, carbon fiber cloth sheet excellent performance can be enhanced to form a complete system, suitable for processing the building load increasing, the engineering function change, material aging, concrete strength grade is lower than reinforcement design, structure crack treatment, environment protection and repair service component.
Q:What is the significance of the determination of total organic carbon in purified water?
The first tube with 5 drops of nitric acid and silver nitrate solution 1ml second tube plus barium chloride solution 2ml third tube plus ammonium oxalate solution 2ml, are not allowed to turbidity. Take this product 5ml nitrate test tube, in ice bath cooling, adding 10% potassium chloride solution and 0.1% 0.4ml aniline two 0.1ml sulfuric acid solution, then slowly adding sulfuric acid 5ml, shake the tube in 50 DEG C water bath for 15 minutes, the solution with the standard blue nitrate solution [for potassium nitrate 0.163g, dissolved in water and diluted to 100ml, shake, precise amount of water into 1ml, 100ml, then the precise amount of water into 10ml, 100ml, and the (per 1ml equivalent to 1 gNO3]0.3ml), with no nitrate water 4.7ml, compared with the same method after color not more, (0.000006%). Nitrite to take this product 10ml, the Nessler tube, and sulfanilamide dilute hydrochloric acid solution (1, 100) and 1ml hydrochloride Naphthylethylenediamine (0.1 - 100) 1ml solution, the pink, and the standard solution of sodium nitrite and nitrite [0.750g (calculated on dry goods), dissolved in water, dilute to 100ml, shake, precise amount of water into 1ml, 100ml, and then precise amount of water into 1ml, 50ml, and the (equivalent to 1 gNO2 per 1ml) 0.2ml), plus nitrite free water 9.8ml, compared with the same method after color, shall not be deeper (.000002%). Take this product 50ml ammonia, alkaline potassium tetraiodomercurate solution 2ml, placed 15 minutes; such as color, with ammonium chloride solution (from ammonium chloride 31.5mg, and no amount of ammonia dissolved and diluted into 1000ml 1.5ml), compared with alkaline solution and free ammonia 48ml iodine potassium iodide solution made from 2ml, not deeper (0.00003%).
Q:Do you make the clay?
Clay soil can not be prepared, it was completed by geological changes over the past ten thousand years. Flower cultivation of soil can be self-made, mud carbon 3 points, coconut bran 2 points, perlite a point. The three proportion is 3; 2; 1.
