300/200 type test sieve for laboratory use, national standard analysis sieve, also known as 300 test sieve or 200 test sieve, experimental inspection sieve, standard analysis sieve, national standard test sieve, laboratory vibrating sieve, laboratory vibrating sieve, numerical control test sieve, digital display Test sieve, powder inspection sieve and standard sieve are standard analysis sieves integrating powder classification and liquid filtration; suitable for laboratories, quality inspection rooms for effective analysis of particle size structure of particles and powders, liquid solids content and Test and analysis of the amount of debris. It has the characteristics of low noise, high efficiency and high precision. The new recommended power generator is used to generate multiple high-frequency vibrations, and the samples are filtered efficiently; the standard sieve body ensures the high precision of sample analysis; the electronic delay device can set the same screening time of the same material according to the need to ensure the analysis of the sample The uniformity of data reduces the inspection error to a lower level, so that effective judgments can be made on product quality.

测定型芯砂在常温下的抗剪、弯、压、拉的强度


SFZ型数显铸造型材料发气量测试仪是铸造仪器,型砂仪器,型砂检测仪器,测量型《芯》砂试样受热后,在规定时间内所发生的气体毫升数量,即发气量,可用每克试样发生气体毫升数来表示。主要检测铸造型砂,粘土砂,树脂砂,覆膜砂等材料的发气量。

发气性是指型《芯》砂试样受热后,在规定时间内所发生的气体毫升数量,称发气量,可用每克试样发生气体毫升数来表示。发气性的另外一个含义是发气速度,以式样的发气量与时间的关系曲线来表示。造型材料和型(芯)砂的发气性会影响铸件产生气孔或形成夹砂,因此铸造产生中应注意对造型材料发气性的控制,近年来随着化学粘结剂在铸造业中广泛应用,希望在特定的温度条件下,测出气体的体积和发气速度更显重要。

我们参阅了美国铸造师协会(AFS)*的发气性测定仪,它是既符合通用标准又在理论上和实际操作上适合我国标准的发气性测定仪,而且结构简单合理,操作方便,且又能作为灼减量的测定,受到广大铸造工作者的欢迎。主要检测铸造型砂,粘土砂,树脂砂,覆膜砂等材料的发气量。

双盘红外线烘干器 利用红外线灯泡所产生的幅射热能,使被烘烤物中水分迅速蒸发,达到间接测定被测物料含水量的目的。主要用于铸造用原砂. 型砂及其混合料的快速水份测定。它具有无级调温. 烘干速度快.易操作. 可同时烘烤两个试样等优点
