CN101306557A - Production process for manufacturing cement fibre board from fast growth aspen - Google Patents

Abstract

The invention relates to a processing technique of manufacturing a cemented excelsior board by using fast growing poplar, which is characterized in that the method comprises the following steps: cutting a piece of poplar wood into wood wool by using a wood wool making machine; weighing wood wool and cement required by a single excelsior board; dipping the wood wool into water; fully mixing with the cement in an agitator; uniformly spreading the agitated mixture of the wood wool and the cement in to a mould; sending each finished mould into a cooling press; starting the cooling press to press the loose mixture into solid mixture; placing concrete blocks above mould piles which come out from the cooling press for maintaining the mould piles; detaching board blanks from the mould and drying the same in natural condition; and sizing, trimming and sanding the board blanks, spraying color on the same, and processing corners of the same. The processing technique has the advantages of simple processing technique, small equipment investment, small occupied field and controllable output.

Description

A kind of production technology with manufacturing cement fibre board from fast growth aspen

Technical field

The present invention relates to a kind of production technology, can be used for producing the wood wool cement board that in building light-weight partition wall and finishing, uses, belong to the wood-based plate manufacturing process technology field with manufacturing cement fibre board from fast growth aspen.

Background technology

Wood wool cement board is to be raw material with the wood wool, and cement is the artificial board of gelling agent, has insulation, sound insulation, and sound absorption, many good characteristics such as fire prevention can be used as in the light partition wall or secondary decoration of building, have vast market prospect.The wood wool cement board of present domestic use is dependence on import almost, the domestic technology and equipment that not can manufacture wood wool cement board.Though some companies of Europe have commercial wood wool cement board production line to sell, and are introduced into the domestic two aspect problems that have, the one, the production capacity of the equipment design in Europe is all very huge, reaches 165m as the single order of classes or grades at school production capacity of equipment of Dutch Ai Tuo company ³, obviously be that the such emerging market of China does not digest; Because automation degree of equipment is all very high, cause costing an arm and a leg on the other hand, simultaneously occupied ground is big, is unfavorable for that medium-sized and small enterprises set up plants.

Summary of the invention

It is simple to the purpose of this invention is to provide a kind of technology, and equipment investment is low, the wood wool cement board production technology that output is adjustable.

For realizing above purpose, technical scheme of the present invention provides a kind of production technology with manufacturing cement fibre board from fast growth aspen, it is characterized in that its method is:

The first step is cut growth 20cm-30cm to poplar with wood wool making machine, the wood wool of thickness 0.2-0.5mm, and the wood wool width of making decorative panel is 1mm or 2mm, the wood wool width of making partition plate is 3mm or 4mm;

Second step weighed required wood wool of individual wood wool board and cement, and wood wool and cement weight ratio are 1: 2-3;

In the 3rd step, wood wool fully mixes in mixer with cement soak 1 minute-2 minutes in water after, and the mixer rotating speed is controlled at 10 rev/mins-20 rev/mins, and mixing time is 3 minutes-7 minutes;

In the 4th step, be spilled into the wood wool after stirring and the compound of cement in the mould uniformly;

The 5th step, whenever mat formation and finish a mould, it is sent into cold press, and be placed on the below for the treatment of pressing mold tool buttress, open machine fluffy compound compacting, the height of mould buttress is controlled at the 20-40 piece in the lamination process, whenever finishes once piling up neatly integral body and shifts out press and carry out maintenance, and the pressure of cold press is 0.3-0.5Mpa.

In the 6th step, concrete blocks is placed in the mould that comes out from press buttress top, and through the demoulding after the maintenance in-48 hours in 24 o'clock, the slab after the demoulding is finished drying under field conditions (factors).

In the 7th step, slab is carried out sizing cut edge, sanding, color spray and corner processing.

Described cement working strength grade is the decoration white cement of 42.5Mpa.

Advantage of the present invention is that production technology is simple, and is few to equipment investment, and the place is taken not quite, and output is convenient to control again simultaneously.

Description of drawings

Fig. 1 is a kind of production line schematic diagram with manufacturing cement fibre board from fast growth aspen.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, a kind of production line schematic diagram with manufacturing cement fibre board from fast growth aspen, article one, production line is mainly by three wood wool making machines 1, granted patent, patent No. ZL200620049449.8, the shaft type mixer 2 of two outsourcings, article two, 3, one cold presses of forming line 4 are formed, and are 1200mm * 600mm with the production specification, the wood wool cement board of thick 25mm is an example, and concrete production stage is as follows.

Wood wool making machine becomes wide 2mm to the long poplar slicing of 250mm, and thickness is the wood-fibred of 0.2-0.5mm.Measurement process is by every required wood wool 2.0Kg of sheet material and cement 5Kg weighing, the decoration white cement of cement working strength class 4 2.5Mpa.Agitating procedure stirs ladle mixing to wood wool after flooding and cement input, and mixing time is 5 minutes.It is 20 that suppression process is controlled every buttress mould.Concrete blocks is placed in the mould buttress top of coming out from press, maintenance demoulding after 30 hours, and the slab after the demoulding is finished drying under field conditions (factors), at last slab is carried out sizing and cuts edge, sanding, color spray and corner processing.Performance indications through the sheet material of above-mentioned explained hereafter are: density 0.59g/cm ³, MOR 3.5Mpa, thermal conductivity factor 0.08W/ (m.K), acoustic absorptivity 0.60.

Present embodiment production equipment area occupied 250m ², slab maintenance region area is 250m ², output was 160 in 8 hours.
