Description

Известен способ производства H3fleviHfl из термореактивных пластмасс 3 самозапирающихс  пресс-формах с применением конвейера дл  их передвижени .A known method for the production of H3fleviHfl from thermosetting plastics 3 self-locking molds with the use of a conveyor for their movement.

Предлагаетс  поточный беспрессовый способ производства изделий из полиметилметакрилата, заключающийс  в том, что издели  в специальных пресс-формах с зажимными устройствами поступают в нагревательную туннельную печь. После придани  пластмассе в зкотекучего состо ни  пресс-форма по конвейеру поступает з холодильную камеру дл  охлаждени .An in-line bespresso method for the production of polymethyl methacrylate products is proposed, which consists in that the products in special molds with clamping devices enter the heating tunnel kiln. After the plastic is molded, the mold is conveyed by conveyor from the cooling chamber for cooling.

Новым в предложенном способе  вл етс  разогрев и последующее отверждение полимермономерной смеси в специальных пресс-формах в туннельной печи и охладительной камере, что позвол ет механизировать процесс и значительно сократить производственные площади, так как уменьшитс  количество необходимых дл  нагрева и охлаждени  прессов.New in the proposed method is heating and subsequent curing of the polymer mixture in special molds in the tunnel kiln and cooling chamber, which allows to mechanize the process and significantly reduce the production area, as the number of presses required for heating and cooling will be reduced.

Применение предлагаемого способа позвол ет организовать замкнутую непрерывную поточную линию производства изделий из палиметилметакрилата .The application of the proposed method allows to organize a closed continuous production line for the production of products from palimethylmethacrylate.

На чертеже представлена технологическа  схема беспрессового способа произзодства изделий из полиметилметакрилата,The drawing is a process diagram of a bespressovy method for the production of polymethylmethacrylate products,

Полимермономерна  смесь, состо ща  из 60-70% порошкообразного полиметилметакрилата и 30-40% метилметакри.лата (мономера), приготовленна  известным методом, загружаетс  в пресс-офрму специальной конструкции с зажимным приспособлением, обеспечивающи.м выжимание из пресс-формы избытка пластмассы, что гарантирует получение одинаковой толщины. Запирание пресс-форм производитс  на прессе /.A polymeric monomer mixture consisting of 60-70% powdered polymethyl methacrylate and 30-40% methyl methacrylate (monomer) prepared by a known method is loaded into a press-press of a special design with a clamping fixture, which squeezes excess plastic from the mold, which guarantees getting the same thickness. Locking molds produced on the press.

Заполненна  пластмассой пресс-форма по непрерывно действующему конвейеру 2 поступает в туннельную нагреза1-ельную печь ,A plastic-filled mold through a continuously operating conveyor 2 enters a tunnel heating furnace 1,

где нагреваетс  дд гемпературы 130-150°, в течение 4-5 мин. После придани  пластмассе в зкотекучего состо ни  и заполнени  ею всей формующей полости, пр|сс-форма по конвейеру поступает в холодильную камеру .е охлаждаетс  до комнатной температуры.where the hectare temperature 130-150 ° is heated for 4-5 minutes. After giving the plastic into a flowing state and filling the entire forming cavity with it, the mold is conveyed to the refrigerating chamber via a conveyor, it is cooled to room temperature.

Разборка пр,есс-формы производитс  после ее выхода из холодильной камеры в прйс1гособлении или пневматическим прессом 5.Disassembling the pr-molds is carried out after it leaves the refrigerating chamber in the position or with a pneumatic press 5.

После разборки и извлечени  издели  пресс-форму очищают сжатым воздухом и в случае надобности (один раз в дес ть запрессовок смазывают парафином.After disassembling and removing the product, the mold is cleaned with compressed air and, if necessary, (once every ten pressings, smear with paraffin.

А - участок подготовки прессмассы и запирани  прессформ.And - a site of preparation of a pressmass and lock molds.

Б - участок съема готовых изделий.B - site removal of finished products.

Предмет изобретени Subject invention

Способ получени  изделий из полиметилметакрилата в самозапирающейс  пресс-форме, отличающийс  тем, что, с целью механизации процесса и создани  непрерывности производства, самозапирающиес  пресс-формы с полиметилметакрилатом последовательно нагревают до температуры плавлени  последцйго в туннельной печи и отверждают в холодильной камере.A method of producing polymethyl methacrylate products in a self-closing mold, characterized in that, in order to mechanize the process and create production continuity, self-locking polymethyl methacrylate molds are subsequently heated to the melting temperature of the last in a tunnel kiln and cured in a cooling chamber.
