Q: The small hose attached to the grease gun is coarse or fine at the joint: The small hose attached to the grease gun is threaded with fine thread. Usually M10X1 or Rp1/8.

Q: What's the difference between the rubber hose joint and the stainless steel hose joint?: 1, high water use of this product, the pipeline must be fixed or fixed support bracket, otherwise the product should install anti pull off device. The force of fixed support or bracket must be greater than the axial force, or should install anti pull off device. And because the metal hose pressure resistance better, do not need to install.2, you can choose to use according to their working pressure: 0.25MPa, 0.6MPa, 1.0MPa pipe, 1.6MPa, 2.5MPa, 4.0MPa of the flexible rubber joint, high pressure pipeline equipment, we recommend that customers choose chungha brand stainless steel metal hose, according to the different use of the environment and the size, our biggest can withstand up to 300KG, customers can also ease of use.

Q: What is the essential difference between natural rubber and three yuan ethylene propylene rubber?: The electric property of natural rubber is a kind of non polar material, and it is a better insulating material. When the natural rubber vulcanization after the introduction of polarity factors, such as sulfur, accelerator, so that insulation performance.The dielectric properties of natural rubber are a nonpolar substance that is soluble in non-polar solvents and non-polar oils. Natural rubber is not resistant to cyclohexane, gasoline, benzene and other media, non vulcanized rubber can be dissolved in the above medium, vulcanized rubber swelling. Natural rubber insoluble in polar acetone, ethanol, more insoluble in water, resistant to 10% hydrofluoric acid, 20% hydrochloric acid, 30% sulfuric acid, 50% sodium hydroxide and so on.

Q: How to distinguish the true and false corrosion resistant rubber soft joint?: Soft joint products into your acidic medium, a bubble will know!

Q: Which is better for binding files with rubber tubes and cotton threads?: In fact, the most suitable binding file is the file department I twine, such units are preserved, just to have you asked, hope to adopt

Q: Is it feasible to use rubber material, middle canvas layer and outer rubber material in PVC rubber tube?: Improvement measures: 1, adjust the process, plastic material in place; mixing rubber plastic stability; vulcanized rubbing with low temperature long time vulcanization; 2, test cloth in curing temperature shrinkage coefficient is too big, consider changing cloth;

Q: Must the hose for the cooker be made of oil resistant rubber hoses?: Stove for rubber tube not only to the requirements of oil resistance, acid and alkali resistance, high temperature resistance, aging resistance and flame retardant have strict requirements, rubber gas pipe service life in 2 years or so, there will be over the period aging phenomenon.

Q: Do the rubber joint and Y filter need flange connection?: To look at the general caliber, less than DN50 also has threaded connection type (i.e., thread), but flange type is more reliable.

Q: What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?: Silicon rubber tube, also known as silicon rubber tube, ordinary silicon hose can withstand temperature of 250 degrees, high temperature resistant material of silicon hose can reach about 350 degrees. And its tear resistance and elasticity are very good. It is widely used in high temperature environment. If you don't understand, you can ask me

Q: How can the rubber tube be used properly and how to use it properly?: Hose selection and installation caused by improper hose rupture. When replacing the hose, the hose wire length, number, shape and size of the joint should be reasonable, and should try to reduce the degree of bending in the hose; tighten union nut, do not make the hose distorted, excessive bending and twisting will reduce the service life of the hose greatly; some easily friction parts should take protective measures to prevent the hose due to wear and burst.
