Description
Известно получение листового полнметнлметакрилата в металлнческих (дюралевые) формах, состо щих из дгаух листов металла, разделенных между собой прокладками и склеенных по периметру бумаго.It is known to produce sheet full-metal methacrylate in metallic (duralumin) forms consisting of two sheets of metal sheets separated by spacers and paper glued along the perimeter.
Формы после заливки их полимеризационной смесью и полимеризации разнимаютс дл отделени листов игеталла от блока полиметилметакрилата . Листы металла могут быть вновь направлены дл изготовлени форм, после предварительной замочки в ваннах с гор чей водо и удалени бумаги и приставшего к металлу полимера.After pouring them into the polymerization mixture and polymerization, the forms are separated to separate the igethall sheets from the polymethyl methacrylate unit. Sheets of metal can be re-routed to make molds, after pre-locking in the baths with hot water and removing paper and adhering to the metal polymer.
Процесс замочки и удалени nOvinMepa осуществл етс также отжигом листовметалла в электрической печи. Однако как в нервом,-так и во втором случае поверхность металла со временем портитс и выводитс из производства. После чистки листы металла нссбходилю выпр мл ть, мыть, сушить, протирать спиртом и формовать.The process of locking and removal of nOvinMepa is also carried out by annealing the sheet metal in an electric furnace. However, as in a nerve, and so in the second case, the metal surface deteriorates over time and is removed from production. After cleaning, sheets of metal should be straightened, washed, dried, cleaned with alcohol and molded.
Описываемый способ лишен указанных недостатков и отличаетс тем, что при этом примен ютс покрыти , не содержащие веществ, разлагающихс нри нагревании с выделением газов. Дл этой цели листы металла покрывают слоем желатины казе1иа, полимернзациоииой смеси или нитролака.The described method is devoid of these drawbacks and is characterized in that it uses coatings that do not contain substances that decompose when heated with evolution of gases. For this purpose, metal sheets are coated with a gelatin casein, polymer mixture or nitrolac.
П р и м ер I. Готов т водный 10--20%-иы раствор технической х елатины с добавкой до 5% глицерина. Раствор в гор чем состо нии, вручную или пульверизатором, нанос т на всю рабочую поверхность металла , после чего листы с нанесенной пленкой сушатс . Затем листы металла с высохшей пленкой формуютс , сушатс , заливаютс полимеризационной смесью и подвергаютс полимеризации. По окончании полимеризации формы разнимаютс и листы металла вновь направл ютс на формовку или, если пленка повреждена, то она вновь наноситс но вышеописанному способу.EXAMPLE I. An aqueous 10--20% solution of technical x elatin is prepared with the addition of up to 5% glycerol. The solution in hot condition, manually or by spray, is applied to the entire working surface of the metal, after which the sheets with the applied film are dried. Sheets of metal with a dried film are then molded, dried, filled with a polymerization mixture and subjected to polymerization. At the end of the polymerization, the forms are separated and the metal sheets are re-directed to the molding or, if the film is damaged, it is again applied to the above-described method.
Пример 2. То же, что и в примере первом, но дл покрыти беретс раствор казеина в водном растворе щелочи.Example 2. Same as in Example 1, but a casein solution in an aqueous alkali solution is used for coating.

Предмет изобретени Subject invention
Способ получени блочного полиметилметакрилата в металлических формах, отличающийс тем, что, с целью уменьшени адгезии полимера к металлу, поверхность последнего покрываетс слоем желатины , казеина, полимеризационной смеси или нитролака.The method of producing block polymethylmethacrylate in metal forms, characterized in that, in order to reduce the adhesion of the polymer to the metal, the surface of the latter is coated with a layer of gelatin, casein, polymerization mixture or nitroline.
