Pipes include many, such as PPR pipes, PVC pipes, UPVC pipes, copper pipes, steel pipes, fiber pipes, composite pipes, etc. The most common and commonly used ones are PVC pipes, steel pipes and water pipes. In home decoration, we often encounter this kind of problem: how to buy the pipe, which is better or not? How do we judge this? In fact, there are many ways to know the quality of these products, etc. Can be identified.
Six-point pipe purchase method:
First, it is the "touch" texture. In general, coarse particles are likely to incorporate impurities.
Second, it is a "look" color. PP-R pipes are mainly white, gray and green. Consumers often think that white is the best. In fact, color is not a criterion for judging quality.
Third, it is the smell of "smelling". The main material of the PP-R pipe is polypropylene. The good pipe has no odor, and the poor one has a strange smell. It is likely to be blended with polyethylene instead of polypropylene.
Fourth, it is "pinch" hardness. The PP-R tube has a considerable hardness, and it is possible to pinch the deformed tube, which is certainly not a PP-R tube.
Fifth, it is "ç ¸" flexibility. A good PP-R tube, "rebound" is good, easy to smash naturally is not a good PP-R tube. However, the hardness is not equal to the elasticity. Some manufacturers increase the hardness by adding too much impurities such as calcium carbonate, so they are not broken, and they are easy to be brittle after a long time.
Sixth, it is "burning" smoke and smell. The PP-R tube, which is mixed with recycled plastic and other impurities, emits black smoke and has a pungent odor. After burning a good material, not only will it not emit black smoke or odor, but after burning, the molten liquid will still be very clean.
Need to pay attention to the purchase
First, when the pipe is purchased, you must first understand the product information. In particular, its material, the quality of raw materials determines the quality and age of the product. Comprehensively compare products to find the best value for money product purchase. It cannot be said that only the price of the product is emphasized, and the quality of the most important product is ignored.
Second, if you don't know how to understand this product, you must find someone who knows the product to follow the purchase of the pipe. This way, you don't have to buy products that you don't need.
An Industrial Syringe Pump is a high-profile OEM product with compact
structure and support for open integration. It is mainly used for customized equipment and instruments. It turns out that the syringe pump is so useful for High-precision and complex multi-command fluid processing such as bacterial culture, sampling and testing, biological analysis, microfluidic chip automatic slide chromosome analysis, and DNA sequencing. High precision Ultra stable Programmable Easy to integrate Long life Multi-function Powerful instruction operating system Automatic transmission / automatic dilution / automatic dispensing / automatic dripping / automatic
drainage
·Transmission Basic transmission/delayed transmission/multi-level command transmission
Example: High-precision dosing, cyclic proportional dilution, and timing drainage
·Filling
One-time extraction divided transmission Basic filling/delayed filling/multi-level command filling
Example: Extract infractions and transmit at once (Note: The speed is adjustable, and the single transfer volume is adjustable; the user can directly select the
stored instructions-15 groups.) Controlled by PC software input instructions, it can automatically complete complex and extensive fluid
processing (transmission/dilution/distribution/dropping), providing a more stable and efficient solution for
the high-precision transmission of trace fluids.
