(54) Composition of container glass<br />

(57) The invention relates to the glass industry,<br />

namely to the glass that can be used for manu-<br />

facture of containers.<br />

Summary of the invention consists in that the<br />

composition on base of SiO 2 , Na 2 O, CaO, Al 2 O 3<br />

and colouring agents contains the following<br />

oxidic ratio, wt %:<br />

SiO 2<br />

65,00...73,40<br />

Na 2 O 10,00...14,00<br />

CaO 8,00...13,00<br />

Al O 2 3<br />

1,10...5,50<br />

MgO 0,06...1,20<br />

K 2 O 0,03...0,35<br />

SO 3<br />

0,07...0,50<br />

P O 2 5<br />

0,01...0,10<br />

Fe O 2 3<br />

2,50...3,50<br />

Cr O 2 3<br />

0,30...0,50<br />

MnO 0,10...0,70<br />

NiO 0,04...0,06.<br />

The result of the invention consists in enhanc-<br />

ing the chemical stability and improving the<br />

physical and mechanical properties of the<br />

glass, as well as of the production quality, in<br />

expanding the raw material base and the<br />

colour gamma in the glass industry.<br />

(54) Состав тарного стекла<br />

(57) Изобретение относится к стекольной про-<br />

мышленности, а именно к стеклу, которое<br />

может быть использовано для изготовле-<br />

ния тары.<br />

Сущность изобретения заключается в том,<br />

что композиция на основе SiO 2 , Na 2 O, CaO,<br />

Al 2 O 3 и красящих агентов содержит сле-<br />

дующее соотношение окислов, масс. %:<br />

SiO 2<br />

65,00...73,40<br />

Na 2 O 10,00...14,00<br />

CaO 8,00...13,00<br />

Al O 2 3<br />

1,10...5,50<br />

MgO 0,06...1,20<br />

0,30...0,50<br />

MnO 0,10...0,70<br />

NiO 0,04...0,06.<br />

Результат изобретения заключается в<br />

повышении химической стойкости и улуч-<br />

шении физико-механических свойств стек-<br />

ла, а также качества продукции, в рас-<br />

ширении сырьевой базы и цветовой гаммы<br />

в стекольной промышленности.<br />

(54) Tulpină de fungi Penicillium expansum<br />

producătoare de celulaze<br />

(57) Invenţia se referă la biotehnologie, în particu-<br />

lar la o tulpină de fungi, care poate fi utilizată în<br />

industriile microbiologică, alimentară şi<br />

farmaceutică.<br />

Se propune o tulpină de fungi Penicillium<br />

expansum producătoare de celulaze, depusă<br />

în Colecţia Naţională de Microorganisme<br />

Nepatogene a Republicii Moldova cu nr. CNMN<br />

FD 05 C. Tulpina se caracterizează prin<br />

activitate celulozolitică înaltă a complexului<br />

enzimatic ce conţine endoglucanaze, celobio-<br />

hidrolaze şi β-glucozidaze, activitatea cărora<br />

constituie 42,43; 2,07 şi 4,08 U/ml, cores-<br />

punzător.<br />
