What are the commonly used materials for home elevators?

Home elevator materials

Home elevators refer to elevators installed in private residences and used only by a single family member. It can also be installed in a building that is not used by a single family as a tool for a single family to enter its residence, but the public or other residents in the building cannot enter and use the home elevator. The load cannot exceed 400kg, the speed does not exceed 0.4m/s, the car area is less than or equal to 1.6m2, and the lifting height is less than or equal to 12 meters. According to statistics released by the Ministry of Internal Affairs and Communications of Japan on July 10, 2007, Japan has the largest proportion of the elderly population among 37 countries with a population of 30 million or more, making it the world's number one aging country. Aging is more prominent. In family residences, it is recommended to install home elevators in three-story buildings, and home elevators generally take 2-5 people. The siding is made of SMC composite material. At present, domestic elevators are generally used for villa installation, and the wall panels of domestic elevators are made of metal materials. SMC composite material molded elevator wall panels are made of SMC composite materials through a compression molding process. SMC composite material elevator wall panels have excellent characteristics such as light weight, high strength, smooth surface, and heat insulation. SMC composite material is the abbreviation of Sheet molding compound, that is, sheet molding compound. The main raw materials are composed of GF (special yarn), UP (unsaturated resin), low shrinkage additives, MD (filler) and various additives. It first appeared in Europe in the early 1960s. Around 1965, the United States and Japan developed this technology one after another. In the late 1980s, my country introduced advanced foreign SMC production lines and production techniques. SMC composite material has the following advantages:

1. Home elevator is environmentally friendly and green

SMC composite material is a kind of halogen-free and no harmful substances to the human body. It is a new type of environmentally friendly material to meet the needs of future green development.

2. Household elevators are resistant to chemical corrosion

SMC composite materials have good corrosion resistance characteristics such as acid, dilute alkali, salt, organic solvents, seawater, etc., while metal materials are not acid resistant and easy to corrode.

3. Lightweight and high strength home elevator

Specific strength and specific modulus are one of the indicators to measure the bearing capacity of materials. The specific modulus of SMC composites is equivalent to that of steel, but its specific strength can reach 4 times that of steel.

4. The home elevator has good fire and flame retardant performance

SMC composite material is fire-resistant and flame-retardant; the material is tested by the national authority as a Class B non-combustible material

5. Good household electrical heat resistance

SMC composite materials have the ability to maintain their physical properties in harsh high-temperature environments. Its working temperature is minus 60 degrees to 150 degrees, and its thermal deformation temperature is above 280 degrees.

6. Low thermal conductivity and small expansion coefficient

When there is a temperature difference, the thermal stress generated is much smaller than that of metal, and the heat preservation performance is good.
