Description

Artificial white marble view guardrail handicraft production method

Technical field:

The present invention relates generally to a kind of production method of handicraft, relates in particular to a kind of artificial white marble view guardrail handicraft production method.

Background technology:

Along with further implementing of reform and opening-up and policy of enriching the people, the town and country construction develop rapidly of China, the distance of city and villages and towns in rural areas is more and more littler, and the town and country looks are maked rapid progress, and earth-shaking variation is taking place in particularly vast small town, rural area, rural area.The villa rustica in rural area begins with the high buildings and large mansions ratio in city beautiful.People are increasingly high to work and living environment requirement, and environmental protection and beautifying and decorating have become people's active demand in the heart.People mostly need a kind of elegant in appearance, economical and practical road and view guardrail.Nowadays the guardrail product of producing on the market is main with iron skill, stainless steel, PVC plastics and cement products mostly, though of a great variety, and since very inharmonious with the development of city looks, all be badly in need of updating, be in the stage that is eliminated.Such as: the guardrail of iron skill, reinforcing bar weldering system very easily gets rusty, is out of shape, also easy conduction; The guardrail that some gypsum and cement are processed is anti-to shine poor performance, fracture easy to crack, and through year in year out the weather exposure ice and snow frost etc. that drenches with rain, just the rust decorations are full of stains or spots very soon, and the spot that becomes can't bear, and is very much ugly.Especially their manufacture craft simple, coarse all need be followed and returned back and forth and could accomplish through multiple working procedures such as folding shape, welding, polishing, polishing, japannings.In addition, it is thick, heavy that their profile also slightly seems, costs an arm and a leg, and life cycle is short in addition, and therefore, it beautify, decorative effect be extreme difference also.

Summary of the invention:

The object of the invention is exactly in order to remedy the defective of prior art, a kind of artificial white marble view guardrail handicraft production method to be provided, and it is simple to operate, and the product of producing has reasonable price, advantage such as specious.

The present invention realizes through following technical scheme:

Artificial white marble view guardrail handicraft production method is characterized in that:

(1), the vibrations workbench is set; On the vibrations workbench, master tooling is installed; Master tooling die cavity and the shape of product coupling that needs moulding all have passage on the die cavity sidewall of described master tooling and the master tooling outer wall, and described workbench is provided with air flue; External vacuum system, described air flue and the mutual UNICOM of described passage;

(2), will heat the soft PVC plastic film of baking adheres on the master tooling die cavity; Periphery and vibrations workbench and the sealing of master tooling periphery with the PVC plastic film; Start vacuum system, extract the gas in PVC plastic film and the master tooling die cavity, the PVC plastic film is glued firmly inhale in the master tooling die cavity; After cooling the PVC plastic film is separated, the PVC plastic mold;

(3), the PVC plastic mold is positioned in the holder mould, holder has on the mould rest to stop the cavity of PVC plastic mold outer surface distortion, is fixed to then on the vibrations workbench; With the moulding slurry; Insert in the PVC plastic mold die cavity, put the support that can bear pressure into, open the vibrations workbench; Air dry then can the demoulding obtains the first half of goods in 3-5 days;

(4), prepare the latter half of goods with step (3) with quadrat method after, before dry and the first half of the goods that obtained accurately involutory, faying face must not have pore, combines together, the dry demoulding gets goods.

During operation, master tooling is placed on the vibrations workbench, and stamps some air-vents by certain distance; Adhere on heating Hong soft PVC plastic film to a certain degree on the die cavity on the master tooling then; Be under the prerequisite of positive confinement in vibrations workbench and master tooling, PVC plastic film, start Packing Machine, make PVC plastic film moment be stained with suction firmly in die cavity; Treat after the cooling of PVC plastic film itself and master tooling to be separated, promptly process the fabulous plastic mould of deformability.

After being placed on the corresponding plastic mould rest, the plastic mould that makes is fixed on the vibrations workbench; The slurry that will stir by certain proportioning shovels in the die cavity of plastic mould into; And put into the corresponding keel supporting rib that can bear pressure or bar-mat reinforcement for containing, and place it in again on the vibrations workbench, open electromagnetic shaker; Shake after 3-5 minute, make it be placed on the air dry of smooth place.Get final product the demoulding after 3-5 days, process the first half of product.Make the latter half of product again with same method, product the latter half will unite two into one with its first half after the vibrations of vibrations workbench are accomplished, and starts the vibrations workbench during matched moulds it is combined fully.Matched moulds is wanted accurately must not misplace.Faying face must not have pore, combine together for a full due.The demoulding can be accomplished production of products after 3-5 days.

The raw material of said slurry include white cement, portland cement, white stone, Baihe sand, brightener, Chemical Felter and albarium water; Described heating Hong soft can winning with hand hand-manipulated is advisable, and be soft more good more.Described positive confinement is meant with plastic colloidal cloth or glass glue will shake workbench and master tooling, PVC plastic film thorough seal.The thickness of said PVC plastic film is 0.4mm, and block big I is directly customized to producer according to the volume of product.Said moment, plastic uptake was advisable in the die cavity for range estimation is adsorbed on fully, was generally about one minute.Know with feeling by rule of thumb after the skilled operation.The time of the stirring of said slurry generally is no more than 10 minutes, is main to stir, and does dilution except that the proportioning of pressing albarium water, should grasp appropriateness based on the heat tender feeling condition of weather and get final product.Said vibrations are evenly general consuming time to be 5 minutes.Said demould time is generally was advisable in 5-7 days.

The invention solves guardrail because of the problem that length can be got rusty, corrodes and faded service time, the product of producing does not need japanning, polishing can make smooth surface such as jade; The built-in reinforcing bar in center is to guarantee product strength---shock resistance is counter-bending.With special plastic mould production, make the product that makes have smooth surface, strong, the easy advantage of washing, must not safeguard every year of anti-aging, white clean property.

Advantage of the present invention is:

The inventive method is simple, and is easy to operate, and the product that the method makes has the following advantages:

1, color and luster is different, and protecting look lasting, and bright and clean as beautiful, third dimension is strong, as real white marble guardrail goods;

2, wearability is strong, and resistance to soiling is good, and heat is shone the light as new still that drenches with rain;

3, quality is strong, and for containing, anti-collision and resistance to frost are good with special keel supporting rib or bar-mat reinforcement, and never distortion is durable in use, long service life.

4, human oriented design, beautiful appearance is graceful, the decorative pattern clear and smooth, moulding is graceful, has natural white marble effect, and quality is noble elegant.

5, product design combined type, the installation simple and fast.

6, do not have " three wastes " such as waste residue, waste water, waste gas in the production and discharge, free from environmental pollution.
