Sodium hydroxid,with the chemical formula NaOH, is commonly known as caustic soda. It is a strong alkali with strong corrosivity, generally in the form of flakes,pearls or lumps.Industrial grade Caustic Soda contains a small amount of sodium chloride and sodium carbonate, and is white translucent crystal.Its aqueous solution has an astringent and creamy feel.Sodium hydroxide is prone to deliquescent in the air, so solid sodium hydroxide is often used as a desiccant.It is very soluble in water and emits a lot of heat when dissolved. It`s also soluble in ethanol and glycerin.
Sodium hydroxide (NaOH) is extremely versatile. Used in the production of paper, soap, dyes, rayon, metal smelting, petroleum refining, cotton fabric finishing, coal tar product purification, and food processing, wood processing and machinery industries.
The product is a strongly alkaline substance which belong to 8 grade dangerous goods. with strongly irritating and corrosive, dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and eyes and NaOH can cause burns, and misuse can cause digestive tract burns, mucosal erosion, bleeding and shock.So it`s highly corrosive and requires the "corrosive item" mark.

(1) Poor scientific and technological innovation, the core manufacturing technology lags far behind that of foreign countries, there are few products with independent intellectual property rights, and the varieties are not complete, and the product technology level is different from that of foreign countries by about 15 years.
(2) The investment intensity is low, the research equipment and production technology equipment are backward, the achievement level is low, and the product quality is poor.
(3) The disconnect between science and technology and production, affecting the transformation of scientific research results, the overall strength is relatively low, and the potential for industrial development is insufficient.
Strategic Objectives By 2020, the sensor and instrumentation components should strive to achieve three strategic goals:
--- Focusing on industrial control, automotive, communications, and environmental protection as the key service areas, focusing on sensors, flexible components, optical components, and special circuits, and developing original technologies and products with independent intellectual property rights;
--- Based on MEMS technology, relying on integrated, intelligent and networked technologies to strengthen the manufacturing process and the development of new sensors and instrumentation components, leading the leading products to reach and reach the advanced level of similar foreign products;
---In order to increase variety, improve quality and economic efficiency as the main goal, accelerate the industrialization, so that the domestic sensor and instrument components of the species share of 70% to 80%, high-end products up to 60%.
China's sensor and instrument components industry analysis
The technology and products of sensors and instrumentation in China have been greatly improved through development. There are more than 1,600 enterprises and institutions in the country engaged in the research, development and production of sensors and instrument components. However, compared with foreign countries, the product variety and quality level of sensors and meter components in China cannot yet meet the needs of the domestic market. The overall level is still at the level of foreign countries in the early 1990s. The main problems that exist are:
