Buying a safe (box) requires knowledge of the following:
1. Selection of steel plates: From the thickness, material, and origin of steel plates, these are related to the withstand capacity of safes (boxes) when using electric drills, cutting tools, and special tools such as power saws.
2, forming and welding: This element relates to the cabinet and the gap between the door and the door frame, if it is too large, the flood prevention function is weakened.
3, anti-rust treatment: If this process is not handled properly, it will affect the appearance of the box, in serious cases will cause functional damage.
4, anti-theft mechanism: This element is also the biggest characteristic of the safe (box), because it can not be detected by the user in the box, but it is the key to prevent the technical opening.
5, locks: If the anti-theft mechanism is a surface, the lock is the most important point, because the destruction of locks and imitate the key will destroy the heart of the anti-theft mechanism (after unlocking mechanism with high-carbon alloy steel plate)
6. Auxiliary spare parts: The processing of spare parts must ensure the reliability of their performance to cope with the ever-changing use environment.
7. Appearance: The safe has been gradually removed from bulkiness and monotony, and organic integration with the home environment is the development trend of safe products.
8, the strength of the manufacturer and the brand: the brutal competition in the market to make the product the survival of the fittest, only high-quality products can ensure that the manufacturers invincible.
9, after-sales service: safe is a special commodity, it has a problem, we must have a dedicated, professional after-sales service team, in order to ensure that users at any time without any worries
Also known as electronic chemical materials. Generally refers to the electronics industry uses specialized chemicals and chemical materials, that is, electronic components, printed circuit boards, industrial and consumer production and packaging of various chemicals and materials. It can be divided into substrates, photoresists, electroplating chemicals, packaging materials, high purity reagents, specialty gases, solvents, pre-cleaning dopants, flux masks, acids and etchants, electronic adhesives and auxiliary materials Other categories. Electronic Chemicals with many varieties, high quality requirements, small dosage, demanding on the cleanliness of the environment, product replacement fast, large capital investment, higher value-added products, etc., these characteristics with the development of micro-processing technology more and more obvious.
Electronic chemicals, also referred to as electronic chemical materials, refer to the fine chemical materials that are used in the electronics industry. The electronic chemicals are a kind of special chemicals. As far as the properties of the production process are concerned, they belong to the fine chemical industry. In terms of product use, Belongs to the electronic material industry. According to the classification standard of China's national economy, the electronic chemicals industry belongs to "Specialized Chemical Products Manufacturing Industry" (2662); according to the "Guidelines for Industry Classification of Listed Companies" promulgated by China Securities Regulatory Commission in April 2001, it belongs to "Specialized Chemical Products Manufacturing Industry" C4360 ). They include integrated circuits and discrete device chemistries, such as chip production photoresist, ultra-clean high-purity reagents, ultra-clean high purity gas, plastic packaging materials; color TV with chemical materials, such as color phosphor, CPT Supporting the water-soluble resist, high-purity inorganic salts, organic films, etc .; chemical materials used in printed circuit boards, such as dry film resist, ink, chemical and electroplating copper plating solution and its additives, surface mount process conductive paste , Cleaning agents, liquid solder resist photoresist, adhesive patch, conductive adhesive, solder paste, pre-coated flux, clean and water-based process flux; liquid crystal display devices with chemical materials, such as liquid crystal, photoresist , Oriented films, adhesives, slurries, electrolytes, films and encapsulants, polarizers, etc .; polishing materials, ect.
