1. Melting point concept 1000 a ni.
Melting Point chu thil pakhat thiltihtheihna a ni. Physical principle-ah chuan, melting point chu solid pakhatin a dinhmun a solid state (melting) atanga liquid state-a a inthlakna temperature a ni a, a tlangpuiin TM.-in a sawi thin, a tam zawkah chuan thil pakhata melting point chu freezing point. a ni a, chu chu thil pahnih a ni a, chu chuan melting point pakhat chu a nghawng lian tak a ni{3} one the pressure on the pressure is the melting the melt “ A tlangpuiin atmosphere pakhatah chuan. a pahnihna chu material impurity a ni. Melting point of impurity chu a tlahniam ang. Rubber additives melting point chu products te thianghlimna hriat nan hman a ni.
2. Melting point hmuhchhuah dan thliar hranna .
Melting point chu melting℃ang zelin: initial melting point, middle melting point, final melting point. initial melting point-ah then theih a ni: capillary tube chhunga sample chu liquefied mai a nih laiin temperature Final melting point: Capillary tube-a sample a liquefied vek chuan temperature; Middle melting point: A tir lama melting leh a tawp ber melting inkarah hian, a tlangpuiin capillary chhunga sample chu transparent shape-a melt a nih laiin temperature a kawk a, capillary-a lut turin mitin hmuh theih a ni.
2.1 Melting point detection hi instrument principle angin capillary method leh non-capillary method ah then a ni.
Melting point detection hi manual, semi-automatic leh automatic melting point detection-ah a then theih a, chu chu automation℃a zirin a ni thei.
