The manufacturing of special gas equipment needs to be assembled in the clean room. The clean level of welding area is required to be 100, the clean level of equipment assembly area is required to be 1k, the clean level of electric control assembly area is required to be 100k, the clean level of grinding room is required to be 100k, and the clean level of dressing area is required to be 300k.
Indoor temperature of Level 100 is required to be 19-23 ℃ in summer and 18-23 ℃ in winter; The indoor temperature of 1k, 100k and changing areas should be 22-26 ℃ in summer and 18-23 ℃ in winter, and the relative humidity should be less than or equal to 75%.
The enclosure structure required for Level 100 clean room: 50cm thick anti-static purified rock wool color steel plate for wallboard, FFU keel for primary ceiling and 50cm thick non anti-static purified rock wool color steel plate for secondary ceiling. The floor adopts anti-static elevated floor + epoxy floor, and the primary ceiling of Level 100 indoor is 2.8 m high from the ground. The secondary ceiling is 1.8m high from the primary ceiling.
The required enclosure structure of the clean room of equipment assembly thousand level, electric control assembly 100k level in the dressing area: 50cm thick anti-static purified rock wool color steel plate for wallboard, 50cm thick non-static purified rock wool color steel plate for ceiling (the ceiling is 3m above the ground). The floor adopts anti-static PVC floor. Epoxy floor is required for grinding room.
DEAR Air Separation has established a number of gas investment projects in the world, forming a benign interaction between equipment manufacturing and gas supply, and a new mode of deep cooperation between high-quality capital and DEAR Air Separation, so that the core advantages of the gas investment industry can be reorganized and upgraded, moving towards the road of integration of equipment manufacturing and gas supply, and finally realizing the strategic transformation of equipment manufacturing serving the gas industry. Complete the industrial upgrading from "selling cows" to "selling milk".
DEAR Air Separation mainly produces oxygen, nitrogen, argon, carbon dioxide and other conventional gases, and actively develops rare gases such as helium, neon, krypton, xenon and other special gases.
Relying on the advantage in middle of China, the domestic market has successively established a number of gas investment projects in Henan, Shandong, Shanxi and other places, gradually radiating the whole country. DEAR's intelligent manufacturing and decades of experience in operation and maintenance of gas investment projects will ensure the efficient operation of the equipment.
Looking at the international market, DEAR company's "President’s dream factory" and other key projects in the Philippines are accelerating the global layout.
Taking the intelligent air separation as a name card, taking the country building theory “One belt, one road” as axis, taking the new developing theory as direction, DEAR is providing the energetic Chinese "blood" in the global manufacturing industry!
