The basic state of aluminum plate can be divided into F, O, H, T, W, these five states represent the five kinds of aluminum plate processing and links, different states of aluminum plate performance and price will also have a very big difference, the following is a detailed introduction.

1, F state aluminum plate

F state is also known as the random production and processing state, the organic chemical properties of the mechanical equipment of the F state aluminum plate are not explicitly stipulated, and the customers who purchase the F state aluminum plate generally have special requirements for the performance of the aluminum plate. After purchase, they will carry out the required manufacturing, hardening and heat treatment processes to obtain the required structural mechanics and organic chemical properties.

2, O state aluminum plate

O state is also known as most of the quenching state, O does not have a fine differentiation state, that is, only most of the quenching can get the least compressive strength of aluminum plate products.

3. H-state aluminum plate

The H state is also known as the cold hardening state, which represents the aluminum plate with improved compressive strength after work hardening. H state has many fine differentiation states, such as H18 state, 1 and 8, di a data represents the process :1 is cold hardening, 2 is not most quenched after production, 3 is ultra-low temperature quenched after production; The second number represents strength :1-8, 1, 8.

4, T state aluminum plate

T state refers to the heat treatment process state of the aluminum plate, indicating that the aluminum plate is stable after cold hardening. The T state has a fine differentiation state, which represents a different process treatment, and the state is from T0 to T10. In the T state, Tx51 represents the removal of thermal stress. For example, in the T6 state, after the removal of thermal stress, it indicates T651.

5, W state aluminum plate

The W state refers to the heat treatment and tempering process state, the W state is unstable, indicating that the aluminum plate after heat treatment and tempering is of course timeliness at room temperature, and the W state only represents the aluminum plate in the course of timeliness.

What are the factors that affect the stripping of honeycomb aluminum plate?

1. Surface condition

The oil, dirt and naturally formed loose oxide layer on the surface of aluminum will seriously affect the bonding effect of aluminum honeycomb panel, so it must be cleaned and pre-treated. The aluminum surface can be treated by phosphating or chroming to form a tight chemical conversion film on the aluminum surface, and the aluminum bonding effect after treatment is good.

Second, adhesive

1, the use of polyurethane, epoxy resin room temperature curing adhesive production of aluminum honeycomb panel, its bonding strength is low, for the honeycomb core length of 4mm, panel thickness of 1mm, the total thickness of 10mm aluminum honeycomb panel measured 180° peel strength is about 4N/mm. The bonding property and weather resistance of this aluminum honeycomb panel are poor, and the bonding property decreases significantly after 1 year of use. Aluminum honeycomb panels produced by this process are not suitable for outdoor use, but can be used indoors as decorative partitions.

2. The bonding strength of aluminum honeycomb panel produced by epoxy film process is low. For aluminum honeycomb panel with a core length of 4mm, panel thickness of 1mm, and total thickness of 10mm, the 180° peeling strength measured is about 4N/mm. However, its bonding and weatherability are good, and the peeling strength decreases very little after 1 year of use.

3. The bonding strength of aluminum honeycomb plate produced by thermoplastic film continuous composite process is 3-5 times that of aluminum honeycomb plate produced by the first two processes. It has good adhesion and weather resistance, and its peeling strength decreases little after 1 year of use. Because of the continuous production, high efficiency, can meet the short-term mass supply requirements.

4.Production process

The hot press is used to produce aluminum honeycomb panel. Due to the large pressure of the hot press, it is difficult to control. In order to prevent the aluminum honeycomb core from collapsing, pads are often placed. If the pad is high, it will affect the applied pressure, resulting in low bonding strength. Such as the use of flat thermal composite machine, because the pressure is provided by the elastic force, the pressure can be controlled by adjusting the height, so the bonding strength of the aluminum honeycomb plate produced by this process is high and stable.
