Description
Изобретение относитс к медицинской иромышленности , а именно к производству готоijbix лекарственных средств.The invention relates to the medical industry, namely to the production of medicinal drugs.
Известен олособ изготовлени изделий нз термочувствительных лейкомасс, наносимых на нодложку Многократно, настример п тью сло мн, с сушкой каждого сло .A known method of manufacturing products for heat-sensitive leukomass applied to the substrate Multiple, adjust the five layers, with the drying of each layer.
Однако известный способ трудоемок и не обеспечивает высокого качества издели .However, the known method is laborious and does not provide high quality products.
С целью интенсификации ироцесса изготовлени н повышени качества издели лейкомассу на подложку нанос т однократно слоем необходимой толщины, а сушку провод т ступени ато-комбинированИым энергоподводом, причем первую ступень сушки осушествл ют в течение 4-6 мш-i потоком воздуха при 38-42°С со скоростью 0,4-0,8 м/сек. а последующую сушку -раднацпониым ио.дводом тепла на второй ступени в течение 8-12 миг1. при температуре леикомассы 50--55°С и на третьей стуненн в течение 8--12 мни при 67--70°С.In order to intensify the process of making and improving the quality of the product, the leukomass on the substrate is applied once with a layer of the required thickness, and the steps are dried by an atom-combined power supply, the first drying step being carried out with air flow at 38-42 ° With a speed of 0.4-0.8 m / s. and the subsequent drying is given in the second stage for 8-12 mig1. at a temperature of 50–55 ° C leicomass and at a third temperature for 8–12 minutes at 67–70 ° C.
Способ осуществл ют путем применени ксмбшшрованной тер-морадиационно-конвектив}1ой сушкн в «есколько этапов. На нерво:1 этапе лента со свеженанесенной перцовой массой сохнет етри принудительной конвенции, т. е. обдуваетс со скоростью 0,4-0,8 м/сек в течение 4-б мин. подогретым воздухом с температурой 38-42°С. На втором этапе копвективпую сушку замеп ют терморадиационной при температуре материала 50-55°С и продолжительности 3Tai:ia 8-12 мин. Закаичпваетс сушка па третьем этапе, который вл етс так же термораднациопным, нрн ге мнературе материала 67--70°С в течение 8-12 мин. После этого сухой пластырь охлаждаетс при пормальных услови . до комнатной температуры. На втором и третьем этапах воздух подаетс в зоиы сушки перцового пластыр лишь в количествах, пеобходимых дл удалени растворител . Сушка по такой технолопп- нродолжаетс 25 мин, а сухой пласты 1ь н-меет удовлетворительный товариый вид. высокую клейкость и выдерживает необходимое врем в услови х искусственного старени .The method is carried out by applying a termed convective-convective} 1st dry in several stages. On the nerve: Stage 1, the tape with a freshly applied pepper mass dries into a forced convention, i.e. it is blown at a speed of 0.4-0.8 m / s for 4-b min. heated air with a temperature of 38-42 ° C. At the second stage, the QR drying is cemented by thermoradiation at a material temperature of 50-55 ° C and a duration of 3Tai: ia 8-12 min. Drying is carried out at the third stage, which is also thermo-irradiation, the liquidity of the material is 67--70 ° C for 8-12 minutes. After that, the dry plaster is cooled under false conditions. to room temperature. In the second and third stages, air is supplied to the pepper drying pads only in quantities needed to remove the solvent. Drying over such a tempered lasts for 25 minutes, and the dry seams of the lid have a satisfactory comrade look. high stickiness and maintains the required time in conditions of artificial aging.
