Изобретение относитс к способам изготовлени изделий из пресс-порошков, например искусственного мрамора.This invention relates to methods for making press-powder products, such as artificial marble.
Известен способ изготовлени искусственного мрамора путем последовательного нагрева и охлаждени пресс-материала, наход щегос в пресс-форме под прессом под посто нном давлением.A known method of making artificial marble is by successively heating and cooling a press material that is in a mold under a press under constant pressure.
Однако этот способ не позвол ет достичь высокой производительности, т. к. весь технологический цикл термической обработки прессматериала проходит при сомкнутом прессе.However, this method does not allow to achieve high productivity, since the entire technological cycle of heat treatment of the press material takes place with a closed press.
Целью изобретени вл етс сокращение технологического цикла.The aim of the invention is to reduce the production cycle.
Это достигаетс тем, что форму нагревают до температуры ниже температуры преконденсации , фиксируют ее под прессом, прессуют изделие и окончательно отверждают вне пресса при температуре выще температуры полимеризации смолы.This is achieved by heating the mold to a temperature below the precondensation temperature, fixing it under a press, pressing the product and finally curing it outside the press at a temperature higher than the polymerization temperature of the resin.
Способ изготовлени изделий заключаетс в следующем.The method of manufacture is as follows.
На посту загрузки засыпают пресс-формы исходным материалом и закрывают их пуансонами . Далее собранные пресс-формы пода2At the loading station, the molds are filled with the starting material and covered with punches. Next, the assembled mold pod2
ютс в камеру предварительного нагрева, где их нагревают до температуры ниже температуры преконденсации. Нагретые пресс-формы поступают Б пресс, где производ т прессование материала и смыкание пресс-форм любым известным устройством. Далее сомкнутые пресс-формы подают в камеру, где происходит отверждение путем нагрева при температуре выше температуры полимеризации смолы. Поеле этого форму помещают в камеру охлаждени .into the preheating chamber where they are heated to a temperature below the precondensation temperature. The heated molds are fed to a b press, where the material is pressed and the mold is closed using any known device. Next, the closed molds are fed into the chamber, where curing takes place by heating at a temperature above the polymerization temperature of the resin. After this form is placed in a cooling chamber.
Предмет изобретени Subject invention
Способ изготовлени изделий из пресс-порощков , заключающийс в прессовании в предварительно нагретой форме пресс-порошка, последующей выдержке и охлаждении изделий , отличающийс тем, что, с целью сокращени технологического цикла, форму нагревают до температуры ниже темнературы преконденсации, фиксируют ее под прессом, прессуют изделие и окончательно отверждают вне пресса при температуре выше температуры полимеризации смолы.A method of manufacturing articles from press powders, which consists in pressing a powder powder in a preheated form, followed by exposure and cooling of products, characterized in that, in order to shorten the technological cycle, the mold is heated to a temperature below the precondensation temperaturura, fixed the product is finally cured outside the press at a temperature above the polymerization temperature of the resin.
