Add hot mounting material is a thermoplastic, thermosetting material, having a higher glass transition temperature of 130 °. Hot mosaic materials (HM) series, for domestic and foreign various models, specifications mounted machine. Use edge-preserving thermal mosaic materials HM3, you will not take place for your sample edge down side to worry. Main Features 1, hard and brittle texture; 2, when heated at 130 ℃ when softened texture like glass when cold solid; 3, experimental operation is simple, just a small amount of mosaic materials metallographic sample and placed in metallurgical heat mosaic machine, heated to 130-160 ℃ ideal metallographic sample can be made; 4, grinding performance, to ensure the authenticity of the sample specimens, specimens easy to do in-depth scientific analysis; 5, good chemical stability, resistance to generally sour, salty, salt, mineral oil and lower alcohol. Technical parameters 1, ingredients: the case of amorphous polymers; 2, temperature change parameters: thermal deformation temperature 70-90 ℃, long-term use in the range of 60-80 ℃; brittle temperature -30 ℃, melting temperature processing 130-160 ℃, decomposition temperature of 330 ℃; 3, physical and mechanical properties: the relative density of 1.05-1.09 & Water Absorption 0.05% mold shrinkage 0.4-0.7% & 88-92% transmittance refractive index of 1.59-1.60% & lines & expansion coefficient of thermal conductivity of 0.13 & 0.13 a variety of mosaic materials characteristics are as follows: Heat mosaic materials: HM1 black rubbed daily fast sample preparation using conductive samples rubbed black HM2 HM3 speed in black-and sample edge-preserving edges tightly requirement does not fall side of the sample rubbed slow red gap HM4 samples, etc., rubbed speeds rubbed speeds HM5 transparent for inspection site, scale, layer depth, which are required sample fast HM6 white transparent rubbed daily use wore off speed of sample preparation Fast HM7 transparent mosaic materials soluble samples can be removed quickly from the mosaic removed for non-destructive recovery samples and samples of soluble, transparent
