Description

Pierwszenstwo: Opublikowano: 06.XI.1968 (P 129 920) 5.1.1972 64239 KI. 421,4/15 MKP G 01 n, 33/00 CZYTELNIA UKD Urzedu Pa±en*ww*r.Wspóltwórcy wynalazku: Slawomir Hulanicki, Bohdan Glowiak Wlasciciel patentu: Politechnika Wroclawska, Wroclaw (Polska) Przyrzad do wyznaczania kinetyki odgazowania aerozoli Przedmiotem wynalazku jest przyrzad do wyznacza¬ nia kinetyki odgazowania aerozoli.Znane przyrzady do wyznaczania kinetyki odgazowa¬ nia aerozoli dzialaja na zasadzie rejestracji zmiany cie¬ zaru badanej próbki aerozolu. W zwiazku z tym posia¬ daja skomplikowana konstrukcje, a ich obsluga jest trudna.Celem wynalazku jest skonstruowanie przyrzadu cha¬ rakteryzujacego sie nieskomplikowana budowa oraz pro¬ sta obsluga.Istotnym elementem przyrzadu wedlug wynalazku jest retorta, która ma przekrój pionowy i poziomy w ksztal¬ cie prostokata. Przestrzen, w której znajduje sie badany aerozol ma postac cienkiego plastra, co przyczynia sie do utrzymania stalej temperatury wewnatrz badanego materialu, tak w przekroju poprzecznym jak i piono¬ wym.Przyrzad sklada sie z piecyka, w sklad którego wcho¬ dzi blok ogrzewczy 1, laznia piaskowa 2 oraz retorta 3.Ponadto przyrzad posiada chlodzony odbieralnik ciek¬ lych produktów odgazowania 4, biurety pomiarowe 5 oraz urzadzenie sterowniczo-zasilajace 6. 10 15 20 W celu wykonania pomiaru ustala sie temperature pie¬ cyka na okreslona wartosc, a nastepnie do retorty 3 za¬ sypuje sie próbke badanego aerozolu i umieszcza sie ja w lazni piaskowej 2. Retorte 3 laczy sie z odbieralni¬ kiem cieklych produktów odgazowania 4, który dalej po¬ laczony jest z biuretami 5 przed pomiarem napelniony¬ mi woda. Material odgazowujac wypiera wode. Szyb¬ kosc opadania slupa wody jest funkcja szybkosci obje¬ tosciowej wydzielania sie gazów. Funkcje te nanosimy na wykres w ukladzie temperatura — objetosciowa pred¬ kosc wydzielania sie gazów. W ten sposób otrzymujemy krzywa kinetyczna termicznego odgazowania.

Therefore, they have a complicated structure, and their operation is difficult. The aim of the invention is to construct a device characterized by a simple structure and simple operation. An essential element of the device according to the invention is a retort, which has a vertical and horizontal cross-section in the shape of you rectangle. The space in which the tested aerosol is located is in the form of a thin slice, which contributes to the maintenance of a constant temperature inside the tested material, both in the cross-section and in the vertical section. The example consists of a furnace with a heating block 1, sand bath 2 and retort 3. In addition, the device has a cooled receiver for liquid degassing products 4, measuring burettes 5 and a control and supply device 6. 10 15 20 In order to perform the measurement, the temperature of the furnace is set at a specific value and then to the retort 3, the test aerosol sample is sprinkled and placed in the sand bath 2. The retorte 3 is connected to a liquid degassing product collection 4 which is further connected to the burettes 5 before measurement with the filled water. The material displaces water by degassing. The rate of descent of the water column is a function of the volumetric rate of gas evolution. These functions are plotted on the graph in the system temperature - volumetric rate of gas evolution. Thus, we obtain a kinetic curve of thermal degassing. PL
