PVC Lay Flat Hose Within The Pressure Range
PVC Lay Flat Hose Within the pressure range
Plastic hose should pay attention to the use of matters, Hello everyone, today to tell you about the use of pvc wire hose, should pay attention to the seven major issues are as follows.
1. Before using the hose, make sure that the appearance of the hose is abnormal (trauma, hardening, softening, discoloration, etc.) to avoid unnecessary losses.
2. Be sure to use within the specified temperature and pressure range
Regular steel hose manufacturers have reached the requirements of the steel hose industry, mainly temperature and pressure (working pressure and burst pressure). When applying pressure, slowly increase the pressure, so as not to form the impact pressure, damage the hose. The hose changes slightly with its internal pressure and shrinks, and when used, cut the hose into a slightly longer length than you need.
3. Before using the hose to load the liquid, make sure that the hose is suitable for use. If you are unsure, consult a professional.
4. Do not use non-food grade hoses for the production or handling of food products such as drinking water and alcohol transport.

6 .. steel hose in use should try to avoid the following circumstances
Do not touch the hose directly or near the open flame; do not use the vehicle and other rolling hose; in the vicinity of metal parts, do not use in extreme bending state.
7. In the cutting wire hose should be noted that do not let the exposed wire damage to people. Plastic hose characteristics, plastic hose on the plastic cover requirements
Plastic cover is usually made of polypropylene (PP) injection, high-quality plastic cover should be no obvious shrinkage and Phi Feng, mold line should be smooth, accurate size, and with the head with smooth, normal use does not produce brittle Crack, cracks and other structural damage. For example, in the open cover force in the range, flip should be resistant to folding more than 300 times, and no fracture phenomenon.
Plastic hose on the printing requirements
Plastic hose processing usually uses dry offset printing (OFFSET), most of the ink used is UV UV drying, it usually requires ink adhesion, resistance to color. Printing color should be within the required depth, the overprint position should be accurate, the deviation should be within 0.2mm, the font should be complete and clear.
