Phenolic foam material is a polymer organic hard aluminum foil foam product, which is made of a thermosetting phenolic resin. It is light, fireproof, non-flammable, non-flammable, non-toxic, non-dripping, and has a wide temperature range. -196～+200°C) It is an ideal thermal insulation material for HVAC refrigeration projects without shrinkage or embrittlement under low temperature environment. Because of its high closed cell ratio, phenolic foam has low thermal conductivity, good thermal insulation performance, and water resistance. Water vapor permeability is an ideal energy-saving material for insulation. Since phenolic has a benzene ring structure, the size is stable and the rate of change is <1%. The chemical composition is stable, anti-corrosion and anti-aging, especially resistant to organic solution, strong acid and weak alkali corrosion. In the production process foaming, it does not use Freon as a foaming agent in line with international environmental protection standards, and its molecular structure contains hydrogen, oxygen and carbon. When it is decomposed by high temperature, the overflowing gas is non-toxic and tasteless, and is harmless to human body and environment. In line with national green environmental protection requirements. Therefore, the phenolic super composite board is the most ideal environmentally friendly green insulation material for fireproof, heat insulation, energy saving and beautiful appearance.
Phenolic foam has the reputation of “king of insulation materials†and is a new generation of thermal insulation and sound insulation materials. At present, phenolic foam materials have developed rapidly in developed countries and have been widely used in construction, defense, foreign trade, storage, energy and other fields. Of the acoustic insulation foams used in the US construction industry, phenolic materials account for 40%; Japan has also established the Phenolic Foam Popularization Association to promote this new material.
Phenolic resin foam insulation material (15 sheets) phenolic foam is also one of the most promising new insulation materials in the internationally recognized construction industry. Because this new material is essentially different from the usual polymer resin by the addition of flame retardant, it does not burn in the fire, does not melt, does not emit toxic fumes, and is light, non-toxic, and non-toxic. Corrosion, heat preservation, energy saving, sound insulation, low price, etc., and no freon foaming, no environmental pollution, good processability, convenient construction, its comprehensive performance is currently unmatched by various insulation materials. It is commonly used for insulation of central air-conditioning systems in high-rise and high-rise buildings such as hotels, apartments, hospitals (Hong Kong's advanced building central air-conditioning systems have been mostly converted to phenolic foam in recent years). It has undisputed comprehensive advantages for refrigeration of cold storage, cold storage, insulation for industrial pipes and equipment such as petrochemicals, building partitions, exterior wall composite panels, ceilings, sound absorbing panels, etc., and solves the fireproof performance of other organic materials. Ideal, and the inorganic material has a large water absorption rate, easy to "condense", and skin itching during construction. It is the third generation of the best insulation material for air conditioning systems and various electrical appliances.
In addition, in recent years, some foam materials have been widely used in some large and medium-sized cities in China, but due to their poor flame retardant properties and the emission of toxic gases, phenolic foam materials may be replaced and become very Competitive new building materials.
Electric recovery winches are more and more popular after COVID-19. To rescue a car around 2ton from muddy road, Electric Winch 5 ton is enough. See below fast speed 12v Winch
The capacity of winches differ from 2000lbs to 20000lbs. Normally winch line pull below 5000lbs are for UTV/ATV, winch line pull between 8000lbs and 15000 lbs are for cars like Jeeps, winches over 15000lbs are designed for trucks.
There are also DC electric hydraulic winches from 10000lbs t0 20000lbs. To install such winches, hydraulic pumps are needed.
Car Winches or electrical 4x4 winches, they are commonly available with either a 12V DC or a 24 V DC motor.so confirm the winch voltage you need before buying a winch. And the voltage does not affect the winch motor housing shape, however the inside motor quality sometimes will. There`s almost no difference between the price of 12v and 24v.
Electric Recovery Winches are powered by a motor that runs off either your vehicle's battery or power steering pump. The vehicle's battery power is transferred through the winch's motor to the gear train, causing the winch drum to rotate the rope or cable in a rapid spinning motion.
When choose an electric winch, take the maximum load that you expect to winch and multiply it by 1.5, then you`ll know which one to choose.
The weight rating of these off road winches is based on the first wrap of the cable around the drum. With each layer of cable, the pull capacity actually drops, so when in doubt, go larger. Below is an example of winch performance of each layer for your reference.
Besides, if you need a fast speed winch, pls also take a look at the gear ratio your suppliers offered. As for winches in 12000lbs, the normal gear ratio is 265:1, if you prefer fast speed, you may choose 158:1, which means the actually line of pull may be smaller at the same time.
