Q:Acid burette and burette why different structure: A frosted glass knob with a Teflon plug instead of acid burette, the high price of some, but not afraid of corrosion lye, a general acid burette.

Q:Excuse me: how can a pen with a rubber tube attract more ink?: If this can not be solved, you can suck a part of the pen out, inverted (NIB upward), gently knock, so that ink into the hose, and then continue to suck ink, repeatedly, so that the pen "drink" full".

Q:Does the rubber tube affect the engine in the car's tank?: I don't know what you mean by that, but the car's tank itself needs to be sealed and no clutter is allowed

Q:Excuse me, how can I get waterproof wires in the water?: The wire connector that enters the water can be "waterproof" and "waterproof"Waterproof joints, as the name suggests, can be applied to the water environment, providing safe and reliable connector joints. For example: LED street lights, lighthouses, cruise ships, industrial equipment, sprinkler and so on, all need to use waterproof joints.

Q:How can the tightness of rubber tube and metal pipe joint be ensured?: To see what kind of material hose, small 1MM~2MM, if the inner pressure then add hoop.

Q:Toilet hose and water tank joints leaking, how to repair?: No rib sleeve, the use of pipe outside the buckle fixed, sealed, may be the aging of the tube, buckle clamping difficulties and other reasons. If the pipe is aging, you can cut or replace the tube in the aging part. It is difficult to buckle and clamp, so you need to change the buckle.

Q:How to detect the reliability of rubber hose: Hydraulic test verification pressure test: Test hose and assembly under verification pressure, continue 30s-60s, whether to produce leakage, deformation and damage. Compression deformation test: keep 1 minutes under the specified pressure (work pressure, verification pressure or other pressure below the proof pressure), measure the length and diameter of the hose, twist angle and bend. Bursting pressure test: Determination of the pressure at which the hose burst during the specified step-up rate. Leak test: save 5min at 70% of the minimum blast pressure, and check again and again for leaks or damage. Due to the fact that water is often used in tests, the pressure and leakage pressure at normal temperatures may be slightly lower at normal temperatures.

Q:How can we prevent the aging of rubber tubes?: Formula design is the most important. Rubber formula design is directly related to the service life of the product!

Q:What are the properties of an oil resistant rubber hose?: The performance of the extended product is accompanied by a rubber hose in life in many areas already occupy a crucial position, which makes the hose detection is important, especially for the rubber pipe detecting water, oil and gas and other purposes.

Q:Between the two flanges in the middle of the rubber pipe, what is the name of the connection?: Rubber flexible joint is also called rubber flexible joint, flexible rubber joint, flexible rubber joint, rubber shock absorber and so on.
