I. Introduction ultra-clean aerosol cleaners W5000 is a water-based cleaning agent, suitable for reflow ovens, wave soldering furnace cleaning and maintenance, production lines and a variety of devices that can remove all flux residues and oil improve reflow oven heating efficiency. This product decontamination capability, a variety of new and old dirt residue can quickly and efficiently achieve the desired cleaning results. Wipe after use without leaving stains without damaging the surface. Nontoxic, harmless, non-CFC, does not destroy the ozone layer. As electronic products small, lightweight, precision-oriented development, electronic cleaning in manufacturing becomes increasingly important, as opposed to traditional solvent-based cleaning agent, W5000 safe non-flammable, and the material to meet the ever-increasing environmental substances level requirements, comply with the cleaning industry's future direction. Second, the product features a spray foam moderate, even delicate, strong adhesion, easy flow, large coverage area. 2, foam working time of up to 0.5 ~ 2h. 3, rapid infiltration, decontamination capability, a variety of old and stubborn dirt with good cleaning results. 4, relative to traditional solvent-based cleaning agent, effectively reducing the cleaning time and improve efficiency. Relative to the average water-based cleaning agent, eliminating the need for rinsing process, reduce water consumption and no waste water treatment, reduced cleaning costs. 5, nontoxic, harmless, non-CFC, does not destroy the ozone layer. 6, energy - specially formulated to effectively clean cold or heated in a variety of welding equipment. Third, before using methods and techniques 1. 1) Be sure to wear gloves acid, wear protective masks and goggles when necessary. 2) Make sure the oven is turned off. 3) Make sure the oven temperature has cooled (internal temperature of 40 ℃ best) 2. 1) When using this product the first shake. 2) This product will be aligned at the glue stains stains or bad, with the index finger tap nozzle, spray distance of about 10cm, spray angle of about 45 ℃, spray angle can be adjusted as needed. After spraying, wait a few minutes, and so it is fully saturated. 3) When cleaning the furnace, will spray sprayed on at least 3 ~ 5min residue to dissolve the residue, and then wipe with a wet sponge or cloth, not with a dry cloth, to avoid residual colored objects. 3. Instructions for use: 1) the use of adequate and often shake your spray cans. a. vertical holding spray cans spray at 20 ~ 30cm away from the furnace wall and face. b. The foam may maintain 30min ~ 2h, wipe with a damp sponge or towel. c. can be stored and used at room temperature. 2) Do not use the surface temperature exceeds 80 ℃. Do not use a sharp object to pry the lid spray may pierce cans, please follow the instructions covered in spray and wipe should wear long corrosion-resistant gloves, goggles and protective shoes. Wash hands after use and arms. 3) Do not connect the lights, electrical devices, switches on the light bulb, the heating element, thermostat outlet or contact spray or allow spray. Spray may cause a short circuit. 4) Do not let the product touch the floor covering, linoleum, aluminum, chrome, painted surfaces, plastic and a small amount of ink and other materials. 5) Do not use on a continuous or automatic cleaning oven. 6) If the case of contact with eyes or skin, immediately rinse with water 15 ~ 20min. 7) Do not use this aerosol mixed with other solvents (especially the highly volatile solvent), to prevent chemical reactions.
