Embodiment:

The technological process of production;

Design → moulding → fill a prescription → mix and stir → molding → moulding → curing → die sinking → repairing → maintenance → decorate → check → pack → dispatch from the factory

(1) animal litterbin formulation parameter: (ceramic proportion)

Magnesium oxide 38%, magnesium chloride 18%, wood powder 21%, glass fibre 11%, lime carbonate 4%, numb suede 8%, clear water is so that raw material can be pressed into block getting final product.(the important position of putting forth effort can be laid afterburning muscle in inside, as bamboo and wood bar etc.).

(2) mixing and stirring of raw material:

Magnesium chloride is fully dissolved with clear water, and concentration is that mother-in-law's magnesium table 18-22 degree is (according to the height of temperature; With the height of raw materials of magnesium oxide content, adjust mother-in-law's magnesium density, the temperature high density is low, and it is high that the temperature lower concentration is wanted, and contains volume low-concentration and want high, and content high-concentration is low.Content of magnesia requires between 85-97, and content of magnesia can progressively descend with inventory time length, so determines the practical formulation ratio after will measuring content by stages, otherwise, influence product structure intensity, can add perlite in the lightweight prescription, can infiltrate sand in the heavy prescription; Again with magnesium oxide, wood powder, calcium carbonate dry and even, put into the magnesium chloride solution that has prepared then and mix and stir into saccharification soft plasticable material, again fiber is sneaked into to mix thoroughly in moldable and can adorn mould production, obtain the product of any surface finish as need, can be earlier reconcile into fines and cover with paint, lacquer, colour wash, etc. on product surface (being mould intracavity wall) and get final product with a small amount of thin wood powder and magnesium oxide.Raw material mix and stir available stirrer, also available manual operations.

(3) magnesite molding method

Make mud extraction carving product mould by product design, mark parting line according to the die sinking orientation again, be cut into 40 * 70 millimeters rectangular horizontal being inserted on the parting line, and press the 200-300 mm distance and insert branch mould spiral shell cramp with 0.5 mm thick polyester film; Then the fines for preparing is covered with paint, lacquer, colour wash, etc. in the matrix piecemeal of mud carving product thickness 2-3 millimeter.(note compacting, particularly divide mould spiral shell button to do the jail with the fiber material, the lightweight round log stamen that available screw is same thick in the spiral shell buttonhole inserts, and after three hours wooden stamen is rotated once, in order to avoid wooden stamen clings.But) after three days just die sinking repair, speed is closed up model then, locks firm spiral shell with screw and buckles, and sets level.In order to avoid modification, maintenance, is used resene varnish and is coated with 2-3 time, so that the bright and clean durable easy demoulding of model after the refine polishing to absolutely dry under 30-38 degree temperature again.

(4) moulding and maintenance

To produce mould (4) unclamps, evenly be coated with one deck mold oil at the mould inwall, again model is buckled (3) lock jail, be inverted in after making model lock into integral body in the sandpit (2) of (1), with sand model is filled out surely, the fines that will mix and stir (5) adheres on model (4) inwall again, thickness 2-3 millimeter, the fiber material (5) that will mix and stir is again done pie in blocks and is adhered to the mould inwall from bottom to up successively, complete thick 10-20 millimeter.The material loading whole process requires to finish in about 1 hour, puts into latex pressure cuffs (6) then, with inflation, irritates mode such as sand (7) sand pocket (8) water filling and pressurizes in cover, and what force the saccharification formula moldablely is close to the closely knit moulding of die wall.Solidify die sinking in 4-6 hour down through 30-38 degree temperature and take out product, extremely absolutely dry in the maintenance of 30-40 degree temperature again, can decorate.(note: the high fast drying of temperature, temperature is low dry slow, and the too high contraction of temperature is yielding soon; Temperature is too low, does not do also yielding for a long time; Not absolutely dry product can not be decorated, and can not discharge reduction intensity for a long time and modification in case decorate back moisture content)

(5) simulated decorative technology

Maintenance exsiccant sculpture products transfers lime carbonate to scrape the end with resin paint, and it is bright and clean to polish; spray water-repellancy light color resin paint again; carry out the simulated decorative of various material outward appearances after waiting to do and handle, go up transparent resin varnish again 2-3 time after doing, big part product inwall is coated with the waterproof paint protection.Concrete skill and technique is:

1. imitative wood is decorated: colored drawing wood grain on product, or imitative redwood engraving look paint, or paste woodgrained paper, or make other woodenware paint product outward appearance, use the resinous varnish cover then, to ensure that product color is lasting, bright and clean attractive in appearance.
