Description
Известные стекла па основе SiO2, ВоОз, , СаО, MgO, ВаО, Na20 с применением в качеетве ускорителей и осветителей Li20. CaF обладают недостаточно высокой химической стойкостью, что ограничивает возможность использовани их дл изготовлени химически устойчивой лабораторной посуды и аппаратурыСтекло содержит по весу: 312Оз 72,5-73%, AlgOs 6,8-7,0%, ВгОз 3,8-4,2%, СаО 0-0,5%, ВаО 4,8-5,2%, NajO 7,8-8,2%, LbO 0-0,6%, CaFg 2,5%.Famous glass based on SiO2, BOOz, CaO, MgO, BaO, Na20 with the use of Li20 accelerators and illuminators as kachetyv. CaF possess insufficiently high chemical resistance, which limits the possibility of using them for the manufacture of chemically stable laboratory glassware and apparatus. Glass contains by weight: 312 Oz 72.5-73%, AlgOs 6.8-7.0%, VgOz 3.8-4.2 %, CaO 0-0.5%, BaO 4.8-5.2%, NajO 7.8-8.2%, LbO 0-0.6%, CaFg 2.5%.
Предлагаемое етекло содержит те же компоненты, что и известные стекла, но иное количественное содержание каждого из них обусловливает высокие физико-химические и выработочные свойства стекла.The proposed glass contains the same components as the known glass, but a different quantitative content of each of them determines the high physicochemical and working properties of the glass.
Предложенное стекло имеет коэффициент линейного расширени а 20-400° 50-60-10- 1/град, химическа устройчивость по ГОСТ 3184-46 (потери в весе в ,иг/100 см ) при кип чении в воде - 0,3, в 1 н. HaSO,}-0,1-0,4, в 2 н. NaOH-56-65, температура начала разм гчени 550-59°. При многократной обработке на стеклодувной горелке CTCK.IJO совершенно не тускнеет, а спаи не дают треш,ин. В процеесе варкп и длительной выдержки при температуре выработки стекло не кристаллизуетс .The proposed glass has a linear expansion coefficient of 20-400 ° 50-60-10-1 / hail, chemical device according to GOST 3184-46 (loss in weight, ig / 100 cm) when boiling in water - 0.3, 1 n. HaSO,} - 0.1-0.4, in 2 n. NaOH-56-65, temperature of softening onset to 550-59 °. With repeated treatment on a glass-blowing burner, CTCK.IJO does not tarnish at all, and the junctions do not give a trash, in. In the process of warp and long exposure at the temperature of production, the glass does not crystallize.
Водомерные трубки из этого стекла выдерживают перепад температур , больше 130° при нормах ГОСТ 8446-57в70-90 и ПО . Испытани этих трубок в услови х работы на паровых котлах с давлением 32 атм показали, что они эксплуатируютс значительно больше, чем трубки из стекол других составов и при этом остаютс прозрачными. Термостойкость химико-лабораторной посуды из этого стекла превышает 170 (ГОСТ 3184-46).Water-measuring tubes from this glass can withstand a temperature drop of more than 130 ° with the standards of GOST 8446-57 to 70-90 and software. Testing of these tubes under conditions of operation on steam boilers with a pressure of 32 atm showed that they are operated significantly more than tubes made from glasses of other compositions and at the same time remain transparent. Thermal stability of chemical and laboratory glassware from this glass exceeds 170 (GOST 3184-46).
