Abstract
The invention aims to provide an orifice-plate type mesh belt dry technology and an application thereof. In the technology, stainless steel wire in the traditional mesh belt type oven is replaced by a plate type material with orifices. The technology can be applied to drying process in the production process of amino molding plastics.
Description
Technical field
The present invention relates to a kind of orifice-plate type mesh belt dry technology and the application in amino film plastics (being commonly called as urea-formaldehyde moulding powder) production process thereof.
Technical background
Since nineteen twenty, Germany BASF began the research of urea-formaldehyde moulding powder, the existing nearly 90 years history of urea-formaldehyde moulding powder development.Nineteen fifties, China introduces the urea-formaldehyde moulding powder production technology from the former Soviet Union, the beginning suitability for industrialized production.Through 50 years of development, on technology and equipment, all be improved.
Dry technology is one of key technology in the urea-formaldehyde moulding powder production process.Adopt to need the native formula baking oven of artificial stirring to carry out drying the earliest, but this method exists drying efficiency low, defective such as uneven drying is even makes unstable product quality.
Afterwards, people improved drying equipment and drying mode, adopted the net belt type baking oven to carry out drying.In oven interior with stainless steel cloth as the material conveyer belt, the diameter of stainless steel cloth is generally 0.7-0.8mm, mesh length of side 2mm, guipure length: 30-38m, width: 2m.This method makes urea-formaldehyde moulding powder drying process automaticity improve, and has saved labor cost.But in the process of dry materials, baking oven leading portion and stage casing, because temperature rises, material can adhere at mesh, will clear up at set intervals, otherwise can stop up mesh, has a strong impact on drying effect.Especially when changing kind and color, the material cleaning is trouble more.
Summary of the invention
The objective of the invention is to propose a kind of orifice-plate type mesh belt dry technology and the application in the urea-formaldehyde moulding powder production process thereof.
Defectives such as mesh adhesion, obstruction take place easily at present guipure drying plant, and the present invention improves the net belt type baking oven of present main flow, and successful Application is in the production technology of urea-formaldehyde moulding powder.The board-like material of stainless steel wire in traditional net belt type baking oven with punching replaced, and when carrying out drying process like this, board-like material can conduct heat on the one hand, and hot-air can conduct heat by plate hole on the other hand, makes heat transfer efficiency improve, and it is more even to conduct heat.In addition, material also is difficult for being bonded on the web plate, also compares the aspect during cleaning material.The present invention has obtained successful Application at present in the urea-formaldehyde moulding powder drying process of the precious titanium white goods in Hunan, Nanjing Industrial Co., Ltd..

Concrete invention example:
In order to understand the present invention better, specify technical scheme of the present invention below by specific embodiment.
The orifice-plate type mesh belt size: thickness 0.3mm, aperture 1.5mm, hole centre-to-centre spacing 6mm, diamondwise is arranged (see figure 1); Length 10000mm, width 500mm; Running speed: 20m/h; Baking temperature: 90 ℃.
The colored urea-formaldehyde moulding powder that Hunan, Nanjing precious titanium white goods Industrial Co., Ltd. is produced adopts orifice-plate type mesh belt drying technology of the present invention.Wherein the urea-formaldehyde moulding powder production technology is seen Fig. 2.
Drying process is the 3rd step in this production technology.Adopt the present invention, dry materials is even, and thermal efficiency height has improved the flowability of urea-formaldehyde moulding powder, has guaranteed product quality, has reduced energy consumption, has reduced cost, has obtained good effect.
Though the present invention has been described in detail in detail, yet it is not to be used to limit the present invention with preferred embodiment.Any those skilled in the art under the situation that does not break away from the spirit and scope of the present invention, should make various modifications and change.Therefore protection scope of the present invention should be considered as appended claims institute restricted portion.
