Description

Изобретение относитс  к стекольной промышленности, изготавливающей стекл нные капилл ры, например дл  фильтров , примен емых в биохимии, светотехнике , вакуумной технике и т. д. Известен способ изготовлени  капилл ров путем перет жки стекл нной трубчатой заготовки {. Однако таким способом трудно изготавливать стекл нные капилл ры различных диаметров. Наиболее близким к предлагаемому  вл етс  способ изготовлени  стекл нных капилл ров путем заполнени  стекл нной заготовки металлом, например медью, и нагрева в высокочастотном поле индуктора с последующей перет жкой 2. Однако использу  этот способ, невозможно получить полые капилл ры различных диаметров. Цель изобретени  - получение полых капилл ров различного диаметра. Дл  этого по предлагаемому способу нагрев заготовки с металлом ведут до температуры на 200-250° С выше температуры (плавлени  металла. Этот способ позвол ет получать стекл нные капилл ры длиной (до 700 м) и диаметром от долей микрона до дес тков микрон. Способ по сн етс  чертежом. Закрепленную в держателе подаюш;его устройства / стекл нную заготовку 2 с металлической навеской 3 ввод т в высокочастотное ноле индуктора 4 и нагревают металлическую навеску до температуры на 200-250° С, выше ее температуры плавлени . После того, как стекло, нагретое от металла, разм гчаетс  до пластичного состо ни , затравкой захватывают разм гченное стекло, включают подающее устройство / дл  постепенного ввода в зону индуктора стекл нной заготовки, расходуемой по мере выт гивани  стеклокапилл ра . Выт нутый капилл р пропускают через кристаллизатор 5, где:он затвердевает, и наматывают на катушку приемного устройства 6. Изобретение по сн етс  примером осуществлени . Стеклозаготовку с навеской меди помещают в подающее устройство и ввод т в высокочастотное поле индуктора, где нагревают до 1340° С (температура плавлени  меди 1083° С), после чего стекл нную заготовку перет гивают со скоростью 250 м1мин. Внутренний диаметр полученного капилл ра 5-7 мк.The invention relates to the glass industry, which manufactures glass capillaries, for example, for filters used in biochemistry, lighting, vacuum technology, etc. A known method for the manufacture of capillaries by overwrapping a glass tube stock. However, it is difficult to manufacture glass capillaries of various diameters in this way. The closest to the present invention is a method for manufacturing glass capillaries by filling glass blanks with metal, such as copper, and heating in the high-frequency field of the inductor followed by an overload 2. However, using this method, it is impossible to obtain hollow capillaries of different diameters. The purpose of the invention is to obtain hollow capillaries of various diameters. For this, according to the proposed method, heating the billet with metal is carried out to a temperature of 200-250 ° C above the temperature (metal melting. This method allows to obtain glass capillaries with a length (up to 700 m) and a diameter from fractions of microns to tens of microns. Method Fig. 2. The device is fixed in the holder, its devices / glass preform 2 with metal attachment 3 are introduced into the high-frequency zero of inductor 4 and the metal attachment is heated to a temperature of 200-250 ° C above its melting point. heated glass The metal, softened to a ductile state, seized the softened glass with a seed, turned on the feeding device (for gradually introducing into the inductor zone a glass piece consumed as the glass cap was pulled.) The drawn capillary is passed through the crystallizer 5, where: it it hardens and is wound onto the coil of the receiving device 6. The invention is illustrated by an example of implementation. The glass preparation with a copper sample is placed in a feeding device and introduced into the high-frequency field of the inductor, where it is heated to 1340 ° C (t the copper melting point is 1083 ° C), after which the glass blank is overflowed at a speed of 250 m1 min. The internal diameter of the obtained capillary is 5-7 microns.
