Q: What is the cause of the bursting of rubber products and how should they be improved?
Improvement measures: 1.. Adjust the molding sulfuration temperature, adjust the temperature of the upper and lower plate. 2. adjust the exhaust distance and exhaust time. 3. in strict accordance with the mixing process standards or adjust the formula and mixing process, avoid the use of time is too long to place material (fast cooked). 4., in the explosive edge position plus running trough. 5. control the weight of a single adhesive.
Q: Silicone is silicone rubber? Extracted from there?
Inorganic silica gel is a kind of highly active adsorbent material, which is usually reacted with sodium silicate and sulfuric acid, followed by a series of post treatment processes such as aging and acid foaming.
Q: Comparison of physical properties of HNBR rubber material with other rubber materials
Hydrogenated nitrile rubber, referred to as "HNBR" or "H-NBR". It is a new variety of nitrile rubber (NBR).
Q: How can there be a crack in the rubber ring?
In use, high temperature and exposure to sunlight in the air can cause aging and cracking of NBR
Q: Is rubber flame retardant?
Rubber itself is flammable, in the production process can be filled with some flame retardant material, it can reduce its flammability, but at the same time reduce its inherent good performance, such as abrasion resistance, elasticity, etc..
Q: What do you pay attention to when using rubber?
Water: the moisture content has two aspects: rubber in the humid air or rain soaked in water, easy to damage, this is because the rubber of water-soluble substances and hydrophilic components by water extraction solution, hydrolysis or other reasons caused by absorption. Especially in the water immersion and atmospheric exposure of alternating action, will accelerate the destruction of rubber. But in some cases water does not damage rubber and even retard ageing.
Q: What are the causes of fracture in rubber products?
Rubber products appear broken phenomenon, mainly for the following reasons:1, rubber products for a long time led to the phenomenon of fracture;2, too tired lead to rubber products broken;3, long-term exposure to ultraviolet light will cause rubber products broken;4, in the production of the use of chemical additives and materials conflict, resulting in incompatible and broken;5, the production process, the release of time is not appropriate, resulting in fracture (such as scratches);6, abrasive structure is irrational, lead to fracture;7, the use of materials is irrational, leading to fracture is also common;8, materials placed too long, in use, resulting in broken products, resulting in waste.
Q: What is the rubber composition of sole?
The sole of high pressure polyethylene and rubber flavor, rubber and plastic used together.Student: Rubber soled heavy, expensive, not resistant to oil, heat. Variable color.
Q: How can rubber products be softened?
Rubber softener for fluid or semi fluid, dangerous goods, should be stored in the rain (the most important) ventilation dry place shading.A package (drums, plastic barrels, plastic bags), according to the needs of the customer.
Q: Which kind of rubber has the best wear resistance?
In addition, it also has good water resistance, air tightness and excellent adhesive properties. Widely used in various kinds of oil resistant rubber, oil resistant gasket, gasket, sleeve, flexible packaging, soft hose, rubber roller, rubber cable printing and dyeing materials, become the indispensable elastic material in automobile, aviation, petroleum, copying and other industries.NBR has excellent oil resistance, and its oil resistance is second only to that of polysulfide rubber and fluorine rubber, and it has the characteristics of wear resistance and air tightness. Ding Qing rubber is the disadvantage of ozone and aromatic, halogenated hydrocarbons, ketones and esters solvents, it is not suitable for insulation.
