Abstract

The invention relates to a method for processing PS product, wherein it comprises that: preparing it in mould at 80Deg. C for 5-8min; increasing temperature at full load to 90-110Deg. C for 2. 5-3min, until the PS is softened and shaped; the thermal insulation is 0.1-0.2h. The invention can avoid deformation and crinkle condition, not thicken the bend part to improve quality.

Description

The PS container production process

Technical field:

Technical solution of the present invention relates to PS goods processing technique field.

Background technology:

In the prior art, the PS container, particularly PS sanitary equipment that utilize dull and stereotyped PS (polystyrene) to make are generally middle-size and small-size utensil, and as medium and small sanitary equipment such as washbowl, commode basins, the said goods degree of depth is lower, and bending curvature is less.Processing technology is cut flow process, is cut out quality inspection flow process, mould and the sanction cut PS and cut the shove charge flow process of PS, heat up and heat shaping flow process, insulation and surface treatment flow process and form by the sanction of the making flow process of mould, dull and stereotyped PS.Because product depth is lower, bending curvature is less, disposable the finishing of intensification heating shaping flow process of process.The technical problem that above-mentioned production technology exists is that it can not solve PS container production technical problem large-area, high depth.

Summary of the invention:

Technical problem to be solved by this invention is to design a kind of large tracts of land high depth PS container production process.The technical scheme of technical solution problem of the present invention is that it mainly comprises: the sanction of the making flow process of mould, dull and stereotyped PS cuts flow process, cut out that quality inspection flow process, mould and the sanction cut PS are cut the shove charge flow process of PS, the heating shaping flow process that heats up, be incubated flow process, surface treatment flow process; In the making flow process of mould, its mould is made of nonmetal heat-insulating material; Cut in the shove charge flow process of PS workpiece in mould and sanction, mould and sanction are cut and are evenly placed talcum powder between the PS workpiece; Its intensification heating shaping flow process comprises preheating flow process and intensification shaping flow process; The preheat temperature of preheating flow process is 80 ℃, and be 5-8 minute preheating time; The intensification of intensification shaping flow process is to heat up at full capacity, and the institute's intensification degree that heats up at full capacity is 90-110 ℃, and intensification shaping flow process required time is 2.5-3 minute, until the softening shaping of PS; The insulation required time of its insulation flow process workpiece is 0.1-0.2 hour.

Adopt above-mentioned basic technical scheme, it has prevented that effectively the PS workpiece from easily deforming and wrinkling under high depth container processing conditions, and the bending part of head product has guaranteed the quality of product not because of the big attenuation of curvature; Can eliminate the internal stress that PS occurs effectively in process, guarantee the plasticity and the intensity of finished product.

According to above-mentioned basic technical scheme, the optimum temperature rise temperature that heats up is 100 ℃ at full capacity, can prevent effectively that like this PS from producing bubble in softening forming process, improve the qualification rate of product.

According to technique scheme, mould is preferably pottery with nonmetal heat-insulating material.

Owing to adopt technique scheme, the present invention has realized that the degree of depth is not less than 300 millimeters, surface area and is shaped at the PS container more than 1 square metre and makes, solved effectively in PS container processing technology, explosion, distortion and wrinkling technical problem take place in large tracts of land PS workpiece, high depth container forming process easily, eliminate the internal stress that exists in the process, guaranteed the deep processing behind the forming technology and the security of use.

The specific embodiment:

PS bathtub production technology, the sanction that it mainly comprises the making flow process of mould, dull and stereotyped PS cut flow process, cut out that quality inspection flow process, mould and the sanction of cutting PS are cut shove charge flow process, preheating flow process, the intensification shaping flow process of PS, are incubated flow process, the flow process of coming out of the stove, the demoulding and surface treatment flow process.Adopt this technology, the process equipment of use is 10 kilowatts high temperature PS hot melting furnace and a holding furnace.In the making flow process of mould, its mould is made of nonmetal heat-insulating material, and mould is preferably pottery with nonmetal heat-insulating material, and it is measure-alike that the upper surface outer rim of mould and required processing bathtub launch.Cut in the flow process in the sanction of dull and stereotyped PS, dull and stereotyped PS should cut out by the size that required processing bathtub launches and cut, and cuts PS through sanction and need prevent that the workpiece of breakage from going into stove through strict check.Cut in the shove charge flow process of PS workpiece in mould and sanction, mould and sanction are cut between the PS workpiece should evenly place talcum powder, and mould cuts the level that the placement of PS in high temperature PS hot melting furnace should keep the PS workpiece with sanction.The preheat temperature of preheating flow process is 80 ℃, and be 5-8 minute preheating time; The intensification of intensification shaping flow process is to heat up at full capacity, and the institute's intensification degree that heats up at full capacity is 90-110 ℃, and intensification shaping flow process required time is 2.5-3 minute, until the softening shaping of PS; The insulation required time of its insulation flow process workpiece is 0.1-0.2 hour.Under talcous acting in conjunction between the gravity of PS workpiece and PS workpiece and mould, softening PS is along die forming.
