A cor do corindo em placas \u00e9 branca. Em muitos casos, a qualidade do corindo em placas pode ser conhecida apenas pela observa\u00e7\u00e3o da cor do corindo em placas. No entanto, muitos clientes verificam que, por vezes, \u00e9 inevit\u00e1vel que o corindo tabular<\/a> aparecer\u00e3o part\u00edculas pretas ou azuis. Ent\u00e3o, qual \u00e9 a raz\u00e3o do corindo negro?
\nCorindo tabular<\/a> \u00e9 um abrasivo artificial de alta dureza, que tem bons efeitos econ\u00f3micos quando utilizado para abras\u00e3o pesada. O corindo tabular tem uma estrutura microcristalina de \u03b1-Al2O3, alta tenacidade, pode suportar grande press\u00e3o de moagem sem quebrar, e pode cortar camadas de metal mais grossas.<\/p>\n

1. O tempo de fundi\u00e7\u00e3o n\u00e3o \u00e9 suficiente, podendo tamb\u00e9m considerar-se que o processo de fundi\u00e7\u00e3o \u00e9 imaturo, o que resulta na baixa pureza do pr\u00f3prio corindo tabular e no elevado teor de impurezas, podendo a cor apresentar pequenos pontos negros;
\n2. As impurezas negras, tais como as impurezas transportadas pelo corpo, n\u00e3o s\u00e3o limpas ou s\u00e3o deliberadamente misturadas e esfregadas, o que pode fazer com que o corindo tabular apresente pontos negros.
\n3. Ferrugem de ferro. O pr\u00f3prio corindo em forma de placa cont\u00e9m \u00f3xido de ferro, que pode ser removido para efeitos de limpeza. Durante o processo de produ\u00e7\u00e3o, a cor do corindo em forma de placa pode ser impura devido \u00e0 mistura acidental de ferrugem causada por ferrugem mec\u00e2nica;
\nA cor pura e impura do corindo lajeado \u00e9 um dos padr\u00f5es de inspe\u00e7\u00e3o para a qualidade do corindo lajeado, e a qualidade do corindo lajeado n\u00e3o est\u00e1 \u00e0 altura do padr\u00e3o, o que tamb\u00e9m tem uma grande influ\u00eancia sobre a fun\u00e7\u00e3o do corindo lajeado, como dureza e for\u00e7a de moagem. .

The color of the slab corundum is white. In many cases, the quality of the slab corundum can be known only by observing the color of the slab corundum.
