Abstract

A light partition is made from cement, cinder, haydite, water and additive through proportional mixing, stirring, die pressing and curing for more than 7 days. Its advantages are light weight, thin thickness, high anti-earthquake, water-proof, fireproof, antiflex cracking and antishock performance, low cost and reuse of wastes.

Description

The production method of mechanically from industrial cinder, ceramsite concrete light-weight partition board

Technical field

The present invention relates to a kind of material of construction, relate to a kind of production method of utilizing machine-processed haydite, industrial residue to do raw material production mechanically from industrial cinder, ceramsite concrete light-weight partition board specifically.

Background technology

All to adopt cinder and perlite be starting material to the partition wall sheet material of widespread usage in the market, builds based on the holllow building block group, and its cost is higher, weight is about every square metre of 80-120Kg, and this type of partition plate construction cost is higher, and the labour intensity of construction is bigger, globality and functions of use are relatively poor, limited by seasonal construction, be unfavorable for providing fortification against earthquakes, and this type of partition wall timber intensity is low, it is easy to crack that back plate seam is installed, workability is poor, can not follow closely on the wallboard, thereby equipment such as heating and plumbing's sanitary equipment can't be installed;

Summary of the invention

The object of the present invention is to provide a kind of material light, anti-seismic performance is strong, and the waterproof fireproofing performance is good, and processability is strong, machine-processed lime-ash with low cost, the production method of ceramsite concrete light-weight partition board.

The objective of the invention is to realize by following technical scheme:

The production method of a kind of machine-processed lime-ash, ceramsite concrete light-weight partition board, its production process is as follows:

(1), raw material adopts cement, cinder, haydite, water and additive, by following weight proportion:

1 part of cinder 1-1.5 of cement haydite 0.8-1.2 part water 0.3-0.6 part addition material 0.008-0.012 part

Said addition material is slag, flyash;

(2), stir with putting into stirrer after the raw materials by weight metering, stirs make after 5 minutes even, extrusion molding in material mover is transported into single-lead-screw extruding briquetting machine;

(3), carry out maintenance after the extrusion molding, cover plastic cloth natural curing during maintenance more than 7 days;

(4), the partition plate that maintenance is good is put in storage after playing plate, detection, numbering.

The optimum weight proportioning of raw material of the present invention is: 0.01 part of 0.45 part of addition material of 0.93 part of water of 1.3 parts of haydites of 1 part of cinder of cement;

By the partition plate that present method is produced, its material resources mechanical property is as follows:

Advantage of the present invention is:

1, the partition plate of producing with production method of the present invention, unit surface density is 65Kg/m ²For with about 1/4 of thick brick wall, so body of wall is lighter;

2, the partition plate face of the present invention's production is smooth, and size is accurate, and 2 meters guiding rulers detect super ± 1mm of planeness;

3, sheet material is light and thin, can reduce the buildings deadweight, improve shock resistance, various decorative covers can be directly done on the plate surface, as directly scraping the Da Bai swabbing, Puttying wallpaper, ceramic tile, bullet are coated with etc., heat preservation and soundproof effect 90mm plate and common brick 240mm is thick is equal to, the only about 5mm of two-sided decoration thickness (not containing ceramic tile) can increase usable floor area;

4, the partition plate of the present invention's production helps fire prevention for not firing plate;

5, the partition plate water resistance of the present invention's production is good, meets water and does not reduce intensity;

6, anti-folding, the good impact resistance of this plate;

7, the workability of this plate is good, can saw, can bore, can follow closely, and equipment such as heating and plumbing's sanitary equipment can be installed, and easy to use, adaptability is strong, can do multi-purpose body of wall;

But 8, easy construction dry operation, speed of application is fast, labour intensity is low, reduces construction investment, reduces construction costs, water saving, energy-conservation, save manpower and weight handling equipment;

9, plate facade both sides are respectively trapezoidal tenon, tongue-and-groove seam, are convenient to construction;

10, can effectively improve productive labor efficient with the comparison of bulk partition wall, reduce comprehensive cost, not be subject to seasonal restrictions, be easy to guarantee construction quality, increase usable floor area;

11, the present invention utilizes the three wastes, can reach the purpose of utilization of waste material, helps protecting environment again, has high economic benefit and social benefit, is present comparatively ideal substitute products.

Embodiment
