Place the ash dish containing the coal sample on the conveyor belt of the ash rapid tester preheated to (815±10) °C. The coal sample is automatically sent into the instrument and completely ashed, and then sent out, taking the quality of the residue as the quality of the coal sample. The mass fraction is used as the ash of the coal sample.

The ash dish containing the coal sample is gradually sent from the outside of the furnace into a muffle furnace preheated to (815±10) °C, and is ignited and burned until the mass is constant, and the mass fraction of the residue as the coal mass is used as the coal. Kind of ash.

Hot Melt Adhesive For Protective Suit

Hot melt adhesive can be used as a seam adhesive of protective clothing, while absorbing water vapor, blocking pollution sources, and overcoming the above existing problems of protective clothing.

Hot melt pressure sensitive adhesive is a kind of pressure sensitive adhesive, the main components are rubber, resin and rubber oil, etc., need to be mixed and heated into a mushy object. This object is then applied to cotton cloth, tissue, and cotton paper and a kind of adhesive tape appears. The disadvantage of hot-melt pressure-sensitive adhesive is that the viscosity needs to be affected by temperature, and if the temperature is low, the bonding performance can not be achieved.

Advantages of medical protective clothing

1, medical protective clothing is an important part of medical protective Equipment, its basic requirements are to block viruses, bacteria and other harmful substances, so as to protect medical personnel in the diagnosis and treatment, care process is not infected.

2, medical protective clothing should also meet the normal use of functional requirements, with better wearing comfort and safety, such as good moisture permeability, flame retardant performance and alcohol corrosion resistance.

3, medical protective clothing with anti-penetration function, good air permeability, high strength and high hydrostatic water pressure characteristics, mainly used in industrial, electronic, medical, chemical and anti-bacterial infection and other environments.

High-performance protective clothing sealing hot melt adhesive has good air permeability and water absorption, can instantly absorb water beads, not only can bond non-woven fabrics, breathable film and other materials, seal the joint of the protective clothing, and when the protective clothing is damaged or pinhole cracks, it can quickly absorb water vapor, block the entry of external pollution sources, isolation, protection and adhesion. Such protective clothing effectively blocks the spread of the virus and ensures the health of medical staff!
