• foam pipe production process is what?
Answer ： The main control foam production process is this : mixing (raw material mixing high-pressure high-temperature plastic Make compound), Mixing (plastic practicing good compound wheels rolling hypothermia decentralized), extrusion (the final refining good compound patch through the extruder), Sulfide foam (rubber vulcanization fireside pass sulfide edge foam), up tube (tube).
•  Why is the set of foam volume requirements in 2000 meters above?
Answer ： Extrusion foam is the real flow of foam production, output per unit time than the ordinary foam molding to much. The greater output, temperature and the foaming process more stable. Small orders will waste too much, but not unified product size.
•  What is the foam pipe material composition?
Answer ： The main components of nitrile rubber and PVC, the other to fill, plasticizers, and the auxiliary blowing agent category.
•  Those nubuck or profiled allowed to be how do?
Answer ： Originally foam pipe surface is the crust, with its skin is a kind of tube. After grinding machine dedicated grinding from the surface of the belt-sanding or grinding of various shape of the hand sets. Of course some products also need to undergo special processing technology.
•  Why should under a single week or even longer time?
Answer ： Foaming of the production very fast, the normal daily output of 2 million meters can be achieved, but the grinding process is slower. Also, from curing the furnace just foam pipe specifications instability, need about three days the stabilization period. Therefore, the general requirements of customers as soon as possible under the single, easy production of this orderly production.
•  Proofing Why three days or even a longer period of time?
Answer ： Proofing from foam pipe flow, and the cargo was still the same, a process comes. Proofing is usually inserted in the production, so as not to idle furnace furnace. But is there still a precondition for the sample of the cure rate and temperature must be with the existing foam tubes, otherwise it is impossible to make the normal requirements, and color samples, or even styrofoam.
•  Why foam is very difficult to control the color and form in which it was done? Even each color will be subtle difference?
Answer ： Foam materials (plastic foam, foam rubber) Grasping color have a certain degree of difficulty. foam rubber foam plastic palette compared to some difficulties. At the two foam rubber, foam molding and extrusion foam, foam extrusion molding foam palette than more difficult. Even because every time the temperature foam speed and other technology can not do exactly the same which led to the colors or sizes of the cell samples.
•  Foaming of the specifications error is the number?
Answer ： General hole diameter plus or minus 1 mm, unilateralism plus or minus 0.5 mm wall thickness and length tolerances of plus or minus 1-5 mm. Relatively speaking, the small pipe to a small error, the manager has more to error.
• Foam pipe specifications indicated how?
Answer ： First note, foam pipe from the furnace out of sulfide surface is smooth, which is the crust. in the grinding machine grinding through the epidermis after being polished off, the surface becomes nubuck of. Usually foam pipe diameter, unilateralism thickness and length to that required to indicate Mills Smooth or what density, color, the need for a range. In addition to the annotated iron pipe diameter foam pipe and provide the signature intact.
•  Foam rubber tube with EVA foam pipe how distinction?
Answer ： The former Hole is the crust, use a rubber-based material, good flexibility, which is not within the hole Crust, materials used in plastic-based, Compared poor flexibility. But nearly two in the cell density close to the situation, the appearance is very similar, so many people have it as the same product.
•  I assume that iron pipe diameter is 20 mm, then they should choose what hole the foam tube?
Answer ： If air blowing to the presentation, then foam pipe in the hole can be between 16-20 mm; If detergent category to set lubricant, the hole can be between 18-20 mm; If the direct water kits, foam pipe in the hole between 19-20 mm before.
