Difficult to burn rubber and plastic insulation pipe has several advantages
After continuous use, it gradually reflects such a flame retardant effect, and can improve such fireproofing ability under such conditions, which is a kind of fire protection demand in the factory process, which is Not critical. Under the conditions of high temperature and low temperature, the rubber and plastic pipe can be adapted, so it also reflects such a strong adaptability.
The installation procedure of the rubber-plastic insulation pipe is very simple, because it is a heat-insulating material, and the appearance is relatively easy to damage. Therefore, when installing, you need to install it together. Everyone needs to prepare some tools when installing, that is, tape. Because everyone is easy to damage when they are on the cover, when the damage is made, the tape can be used for further protection. This is the installation process, the program is relatively simple.
In addition, what I want to say is that when you install, you should pay special attention to the safety of everyone during the installation. I suggest that you can understand the tutorials in advance when you install them. For those who don't understand, you must consult relevant personnel in time, or directly invite relevant personnel to help you install them. This will protect everyone's safety. It also enables everyone to work smoothly.
The rubber and plastic pipe itself has excellent thermal insulation properties, and has a rubber appearance, which is smooth and flat. Therefore, no additional layer or protective layer is needed during processing, which greatly reduces the pressure during construction. When the equipment is overhauled, the disassembly of the pipe is also convenient, and the material to be removed is still superior in performance, so it can be reused.
Parameter four: moisture permeability;
Simply put, it is the performance of the water pipe, air flow, etc. through the wall of the rubber insulation pipe. Contains two small parameters: moisture permeability coefficient and moisture resistance factor, the unit of moisture permeability coefficient is G / (mspa), the specified performance index is less than or equal to 90, less than or equal to 60, less than or equal to 35; the wet resistance factor is the same.
Parameter five: vacuum water absorption rate;
Is the percentage of water absorption under vacuum conditions, the specified performance index is less than or equal to 10%;
Parameter six: dimensional stability energy;
This is well understood, that is, there is no difference between the size of the label and the specific size in actual use, or the error between the two changes very small, that is, in line with the standard, generally less than or equal to 10% The dimensional stability is very good.
Parameter seven: tear strength;
Refers to the value of the tear that can withstand the rubber and plastic insulation tube, the unit is N/cm, N should represent Newton, is the unit of strength, that is, the tear strength refers to the per centimeter The strength of the force, the specified performance index is greater than or equal to 3N / cm.
When the rubber and plastic insulation pipe itself is used, it is necessary for us all to choose according to reasonable use standards and requirements. If there is no good performance, it is difficult to meet everyone's needs, for example, it has a good performance against aging, which can ensure that we all have a longer service life when using.

hydroponics system-nutrient technique (NFT)
NFT does not give average support to roots. Typically, the roots sit in a long sloping channel irrigation (Fig. 1.1). The nutrient is introduced into the high class of the canal and allowed to flow over the roots after which it drains into the nutrient tank. This is then re-pumped back into the channel to repeat the watering process.
This feed cycle can be intermittent or continuous. An & lsquo; The intermittent 'rss cycle is controlled by the clock and repeated several times per hour. this is sometimes called the "NFT pulse". The NFT pulse usually achieves better aeration of the roots as the roots are exposed to air between each feed. A & lsquo; continuous' rss cycle works non-stop. This is often used in commercial operations.
You can easily grow your favorite flowers at home without muddy mess and need to water your plants regularly.
Hydroponics is an ideal way to grow plants in urban areas. This makes it a great hobby that helps you to relax and it is fun to watch the hydroponic plants grow in the garden nft.
