1, 304 stainless steel is a universal stainless steel material. High temperature resistance is also relatively good, the general use temperature limit is less than 650℃. 304 stainless steel has excellent corrosion resistance and corrosion resistance to intercrystalline corrosion.
2, 316 stainless steel, 18cr-12ni-2.5 Mo due to the addition of Mo, its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under caustic conditions; Excellent work hardenability (no magnetism).
3, 304 and 316 are all austenitic stainless steels, the difference is that 316 adds 2% molybdenum. Thus, the corrosion resistance of 316, especially the chlorine resistance, is better than that of 304. The price is about 20% higher.
Four ways to identify the pros and cons of thermos cups
1, moves a tank insulation sex identification which is the main technical indexes, vacuum cup filled with water, clockwise to tighten the cork or lid, for 2 ~ 3 minutes later with the hand touch and lower cup body appearance, if found obvious cup body and a cup of warm phenomenon, then the tank has lost vacuum degree, cannot achieve good heat preservation effect.
2, trick two identify sealing performance filled with a cup of water upside down for four or five minutes, screw the cover, put the cup flat on the table, or forced to shake a few times, such as no leakage, it shows good sealing performance; In addition to the lid and the mouth of the cup to see whether the rotation is flexible, whether there is a gap.
3, trick three parts environmental protection sex identify the environmental protection of plastic parts is also worth paying attention to the problem, can be identified by smell, if the cup is made with food grade plastic, the smell is smaller, the surface is bright, no burr, long service life is not easy to aging; Ordinary plastic or recycled plastic odor is large, dark color, burr, plastic easy aging easy to break.
1. Before using the new product, please use boiling water (or add some food detergent to scald and wash it several times and conduct high-temperature disinfection).
2, before use, please use boiling water (or cold water) preheating (or pre-cooling) 5-10 minutes, to make better insulation effect.
3, please hurry to the full amount of water, so as not to tighten the lid, boiling water overflow and burn.
4. Please drink the hot drink slowly to avoid burns.
5, do not put milk, milk products and juice and other carbonated drinks for a long time.
6. After drinking, please tighten the lid to ensure hygiene and cleanliness.
7. Wash with soft cloth and food detergent diluted with warm water. Do not use alkaline bleach metal cabbage cloth, chemical cloth, etc.
8, the inside of the stainless steel cup will sometimes contain iron and other substances due to the impact of sheng fang, and the production of some red rust spots, use warm water to add diluted vinegar soaked for 30 minutes, fully clean.
9, to prevent odor or stains, and can be used for a long time clean. After use, clean and dry thoroughly.
