Laminator film is divided into two categories according to equipment and process, one is “ie coating film” and the other is “pre-coating film”; among them, there are two kinds of film and sub-film. The pre-coating film is a process in which a plastic film is rewound in advance and then combined with a paper printed product.
That is, the coating film is a process in which a film coating machine is used to immediately perform film-plastic compounding with a coating film. It is mainly used as a coating film processing factory or a processing workshop. After applying the adhesive to the reel plastic film as needed, it is dried (slightly) composited and pressurized to adhere the paper film together to form a laminating product.we are provide gypsum ceiling tile machine and fiber cement board production line,you can know it.
That is, the coating film equipment has two kinds of automatic and semi-automatic, and its basic working principle is the same; the main process flow includes unwinding → gluing coating → drying → compounding → slitting → finished product stacking.
The pre-coating film is prepared by the pre-coating film processing factory according to the difference in the format of the specification. The glue is coated and re-rolled, and then selected by the manufacturer to be combined with the printed paper. There are three kinds of pre-coated films: hot film, pressure sensitive film and special film. The binding is mainly used in two types of hot film: BOPP, PET (and one is N nylon).
The pre-coating process is mainly pre-adhesive→upper-rolling→sizing coating (hanging type)→curing and cooling→rewinding→cutting→retracting volume→finished packaging. Pre-coating machine: temperature adjustment → roll up → paper feed → heating → compound → slitting → automatic stacking → finished product.
Values: People-oriented, rigorous science, customer orientation, honesty and win-win, values are the principles that must be adhered to in order to achieve the mission.
It is a viewpoint that reflects the beliefs, tendencies, opinions and attitudes of organizational values, and has the role of behavioral orientation, evaluation criteria, and evaluation principles.
Our company is the first manufacturer in China to develop and produce automatic PVC gypsum ceiling production line. It has fully automatic production line（single-side lamination type and double side lamination type), semi-automatic production line and economic type for customers to choose. As the production line uses modular combination, we can give appropriate solution according to customer requirement and budget.
The production of MgO board adopts the wet plate rolling forming process, where the raw materials are measured and weighed through proportioning, mixed and stirred by a mixer (manually or automatically), and rolling forming. Primary curing, demolding and secondary curing in the curing room. Cutting and sanding, quality inspection and packaging. Complete the entire production system. The products are divided into: regular version of MgO board and MgO sanding board.
The mineral fiber board production line includes raw material mixing system, fourdrinier forming system and vacuum pump system, water cutting system, accelerating conveying system, lifting distribution system, board feeding system, drying system, hot air circulating system, board releasing system, board over-turning system, puttying system, small drying system I, coating system, small drying system II, embossing system, small drying system III, cutting system, dust collecting system, packing stacking system, control system.
Calcium silicate board as a new green environmental building materials except the traditional gypsum plate of features outside, it has superior fire performances and the resistance tide, sound insulation, fireproof waterproof heat insulation,light weight and so on. It also has the advantage of using long life. The new type of board is widely used in the building of ceiling smallpox and wall, family decoration and so on.
