|Stainless steel - making materials
Due to the different uses of each product, the processing of raw materials and quality requirements are also different. Generally different stainless steel products, its raw material requirements also vary thickness tolerances, like second-class tableware and mug etc., thickness tolerances generally higher, -3 to 5%, and a thickness tolerance tableware General requirements - 5% -10% steel such requests, hotels with a freezer timber thickness tolerance requirements -8%, dealers thickness tolerance requirements generally between 4% to 6%. At the same time export products will lead to different customers in different raw materials thickness tolerances required. Generally higher export products customer thickness tolerances, while domestic enterprises thickness tolerance requirements are relatively low (mostly because of cost considerations), some customers even ask -15%.304 stainless steel wire suppliers
①DDQ (deep drawing quality) material: refers to a material for deep drawing (red) uses, is it said, the soft material, the main characteristics of this material is higher elongation (≧ 53%), compared with the hardness low (≦ 170%), internal grain grading between 7.0 to 8.0, excellent deep drawability. Many production thermos pot class enterprises, processing their products generally are higher than (BLANKING SIZE / products in diameter), which processed more than 3.0,1.96,2.13,1.98 respectively. SUS304DDQ timber is mainly used for processing these requests higher than the product, of course, working ratio of more than 2.0 products are generally subject to a few times a stretch to complete. If the extension of terms of raw materials can not reach it, deep drawing products in processing products easy to crack, pull wear phenomenon, affecting the rate of qualified products, of course, will increase the cost of manufacturers;Aluminum Suppliers near me
② general material: mainly used for external purposes in addition to DDQ materials, the characteristics of this material is relatively low elongation (≧ 45%), and relatively high hardness (≦ 180HB), internal grain grade of 8.0 to 9.0 rooms, compared with DDQ timber, it is relatively deep drawability somewhat less, it is mainly used in the products can be obtained without thrust, like a class tableware spoon, spoons, forks, electrical appliances, steel uses. But it is compared with DDQ material has an advantage BQ is relatively good, mainly due to the slightly higher because of its hardness.Cheap stainless steel sheets
Bright floor thanks to routine maintenance
1, laminate flooring
Laminate flooring is much easier to maintain than solid wood flooring. When cleaning the floor, to keep the floor dry, do not rinse with plenty of water, local long-term care to avoid floor flooding. Choose for cleaning stains neutral detergent treatment, avoid direct sunlight, rain, moisture and the like.where to buy cheap composite decking
In addition, attention to indoor ventilation, keep the indoor temperature also help extend the life of the floor. Laminate flooring does not need painting and waxing, with solid wood flooring different, do not use sandpaper polished.
2, solid wood flooring
Improper installation and use of solid wood flooring, make qualified products are also quality problems. Solid wood flooring in the maintenance, pay attention to the ground dry and clean.
When laying wood flooring, if not done to deal with moisture, bathroom and room on the ground no good isolation, it will affect the life of the floor. Being soaked with water or alkaline, soapy water will destroy the brightness of paint; summer did not pay attention to pull the curtains, make the bed floor cracking discoloration after exposure to sunlight; open air temperature is too low, so that during the day and night temperature changes, causing the expansion or contraction of the floor too intense, causing the floor deformation and cracking.composite material to cover outside stairs
Floor during use, if that individual from the shell or off the floor, should be taken from the floor, stripped off the old glue and ash, painted with the new plastic compaction. A month to play a wax is the best maintenance method, but before waxing to clean moisture and stains.
Parquet wood floor with respect to the maintenance easier. Keep the floor dry, clean and without dripping mop mop the floor, not alkaline, soapy water and wipe can effectively protect the floor. If the air in your home dry, wet mop may be some or put a pot of water in the heating, humidification humidifier can also be used. Try to avoid the sun drying, in order to avoid premature aging of the paint surface in the long-term UV exposure and cracking.
Local board accidentally contaminated stains should be promptly removed. If oil, can be used cloth dipped in a small amount of detergent in warm water to scrub soiled; if drugs or pigments, stains must be cleared at the end of infiltration such as wood surface before. Floor to avoid prolonged contact with water, especially not in contact with hot water, once the water hits the floor, should be promptly wiped away.
The best play once every three months waxes, stains before waxing the floor surface to be cleaned, often waxing can keep the floor finish to extend the life of the floor. Avoid sharp objects to scratch the ground, do not put too hot things on the floor, try to avoid dragging heavy furniture.composite deck board cladding
