(1) Durability
In the inspection of PB plastic pipe, the material was exposed to oxygen flow at 220 °C, and the oxygen induction time of 35.78 min was obtained, indicating that the high oxidation stability of PB plastic pipe can effectively affect the thermal oxidative decomposition of polymer materials. Inhibition.
The durability of plastics has a very obvious relationship with temperature and stress. The standard "Extrapolation Method (SEM)" specified in the international standard ISOTR9080 continuously tests the results of 8760h with 110 water and 106Pa working pressure, indicating that the PB plastic pipe is at the water temperature. In the case of 70 ° C per year, the performance is stable at least within 50 years, and it has sufficient stability against the aging effects of thermal oxidation.
(2) Flexible bending performance and brittle resistance
Since the PB plastic pipe has a significantly small bending elastic coefficient compared with other plastic pipes, it is naturally bent when no external force is applied, and can be rotated 360 degrees. In addition, since the PB plastic pipe has good crack resistance, the pipe is at -20 ° C. Will not freeze. This article comes from the global plastics network pvc123.com.
(3) Good liquid flow conditions
Due to the high heat resistance of the PB material, in all the plastic pipes, the PB plastic pipe can have a minimum wall thickness without affecting the safety and reliability, and other plastic pipes of the same size as the outer diameter. Compared with the advantage of having a large inner diameter, the liquid has good fluidity and relatively large flow rate, thereby saving hydraulic energy and raw materials. In addition, since the PB plastic pipe wall is smooth, the non-fouling noise is low.
(4) Conducive to connection and laying
Since the PB material has great resistance to stress cracking, the tensile strength and sealing pressure of the pipe at the joint portion will not weaken with time during the joining process, and the PB plastic pipe has good heat expansion resistance, so The tube will not move due to temperature changes, and the joint will not fall off. Naturally compensate for the slight expansion and contraction. If necessary, it can be selected from a variety of typical simple compensation methods.
(5) can prevent algae growth
PB is a highly inert polymer material with high chemical stability. Microorganisms cannot be parasitic, and are the world's drinking water supply facilities that meet health standards.
(6) Processability
Whether it is the plasticity of the PB material itself or the feasibility and durability of a reliable connection with other materials, PB is excellent.
(7) Easy to handle and install
Compared with traditional copper and steel, the quality of the complete water supply facilities using PB plastic pipes and fittings is 1/3 of that of copper, which is 1/7 of that of steel, which greatly saves material consumption and installation expenses.
(8) Reusable
The waste in production can be pulverized into granules, and then put into use after being made into a lower quality product; or it can be converted into heat energy by incineration together with domestic garbage. Because the molecular structure of PB does not contain halides, the products of combustion do not produce corrosive toxic substances and do not cause harm to the environment.
This little SMD LED are largely used for kinds of electronic product, for example: LED indicator, LED back light or some DIY led project. These small SMD RGB LED might not easy for weld by our hand because the small size. However, because of this small size, this RGB SMD LED are easier fit with kinds of small size PCB board.
