O p\u00f3 de quartzo ultrafino \u00e9 um enchimento inorg\u00e2nico neutro de alta qualidade. Possui forte resist\u00eancia a \u00e1cidos, propriedades f\u00edsicas e qu\u00edmicas est\u00e1veis, boa transmit\u00e2ncia de luz, alta diel\u00e9trica, alta resist\u00eancia \u00e0 umidade, resist\u00eancia \u00e0 radia\u00e7\u00e3o, excelente resist\u00eancia a altas temperaturas e altas propriedades de TI, como pureza, baixo teor de \u00edons, baixa expans\u00e3o e baixo estresse. . \u00c9 amplamente utilizado em pl\u00e1sticos, revestimentos, tintas, borracha, cer\u00e2mica, tintas, materiais catal\u00edticos e de filtragem de g\u00e1s e outros campos.<\/p>\n\n\n\n

Entre eles, a ind\u00fastria de alta tecnologia tem requisitos muito rigorosos quanto \u00e0 pureza, tamanho e distribui\u00e7\u00e3o do tamanho das part\u00edculas do p\u00f3 de quartzo ultrafino. Em rela\u00e7\u00e3o \u00e0 tecnologia de britagem atual, o equipamento de britagem ultrafino dispon\u00edvel para minerais de quartzo natural inclui moinhos de bolas, moinhos de agita\u00e7\u00e3o, moinhos de fluxo de ar, moinhos vibrat\u00f3rios e v\u00e1rios classificadores.<\/p>\n\n\n\n

Pr\u00e9-tratamento de quartzo (calcina\u00e7\u00e3o + t\u00eampera em \u00e1gua)<\/h2>\n\n\n\n

A dureza do quartzo \u00e9 7. Se outros minerais forem triturados diretamente, o consumo de energia ser\u00e1 alto e a efici\u00eancia ser\u00e1 baixa. Portanto, a britagem t\u00e9rmica pode ser realizada primeiro, ou seja, o m\u00e9todo de t\u00eampera com \u00e1gua de calcina\u00e7\u00e3o.<\/p>\n\n\n\n

Primeiro, o quartzo \u00e9 calcinado a alta temperatura (900 ~ 1150 \u2103) e depois resfriado com \u00e1gua, fazendo com que o quartzo sofra r\u00e1pida \u201cexpans\u00e3o t\u00e9rmica\u201d e \u201ccontra\u00e7\u00e3o a frio\u201d, resultando em um grande n\u00famero de microfissuras em sua superf\u00edcie e dentro do bloco, reduzindo assim sua resist\u00eancia. , melhore a efici\u00eancia de britagem.<\/p>\n\n\n\n

Quando a \u00e1gua est\u00e1 se extinguindo, \u00e9 melhor n\u00e3o usar piscina porque, quando ela esfria, muitas bolhas de vapor d'\u00e1gua se formar\u00e3o na superf\u00edcie do quartzo. Comparado com a \u00e1gua l\u00edquida, n\u00e3o \u00e9 f\u00e1cil conduzir calor; n\u00e3o \u00e9 f\u00e1cil formar um efeito de \u201cresfriamento r\u00e1pido\u201d.<\/p>\n\n\n\n

Prepara\u00e7\u00e3o de p\u00f3 de quartzo ultrafino por moinho de bolas<\/h2>\n\n\n\n

O moinho de bolas + classificador<\/a> a linha de produ\u00e7\u00e3o completa \u00e9 mais adequada para o processamento de britagem ultrafina de quartzo. Possui as caracter\u00edsticas de alta brancura do produto, boa forma e brilho, indicadores de qualidade est\u00e1veis e forte controlabilidade da distribui\u00e7\u00e3o do tamanho das part\u00edculas.<\/p>\n\n\n\n

No entanto, desde moinhos de bolas<\/a> e os classificadores t\u00eam fun\u00e7\u00f5es e focos diferentes e geralmente s\u00e3o produzidos por duas empresas, muitas vezes h\u00e1 diferen\u00e7as em conceitos como sa\u00edda, portanto a correspond\u00eancia dos dois deve ser considerada ao selecionar e projetar equipamentos. Se a aplica\u00e7\u00e3o n\u00e3o for razo\u00e1vel, causar\u00e1 restri\u00e7\u00f5es funcionais, alto consumo de energia e baixa efici\u00eancia. A coopera\u00e7\u00e3o adequada pode aproveitar ao m\u00e1ximo as respectivas vantagens, complementando todo o sistema, alcan\u00e7ando o dobro do resultado com metade do esfor\u00e7o e sendo muito eficiente.<\/p>\n\n\n\n

Al\u00e9m disso, a alta dureza do quartzo causa s\u00e9rio desgaste nos equipamentos e contamina os produtos. A prote\u00e7\u00e3o resistente ao desgaste deve ser realizada no equipamento, especialmente p\u00f3 de sil\u00edcio de alta pureza de grau eletr\u00f4nico. Todas as pe\u00e7as est\u00e1ticas, como cavidades e tubos, devem ser feitas de materiais cer\u00e2micos ou org\u00e2nicos resistentes ao desgaste. Materiais, etc., para o forro. Os moinhos de bolas geralmente usam placas de revestimento de alumina ou placas de revestimento de pedra esf\u00e9rica.<\/p>\n\n\n\n

Prepara\u00e7\u00e3o de p\u00f3 de quartzo ultrafino por moinho vibrat\u00f3rio<\/h2>\n\n\n\n

O moinho vibrat\u00f3rio<\/a> tem as vantagens de baixo ru\u00eddo, estrutura compacta, tamanho pequeno, peso leve, baixo consumo de energia, alto rendimento, tamanho de part\u00edcula de moagem concentrado e nenhuma polui\u00e7\u00e3o. O p\u00f3 de sil\u00edcio ultrafino de alta pureza e grau eletr\u00f4nico produzido \u00e9 um p\u00f3 esf\u00e9rico.<\/p>\n\n\n\n

Moinhos vibrat\u00f3rios<\/a> geralmente usam alumina como revestimento, e a m\u00eddia \u00e9 principalmente bolas de alumina. A frequ\u00eancia de vibra\u00e7\u00e3o afeta diretamente a efici\u00eancia de moagem do produto, bem como a perda do equipamento e o consumo de energia. Determinar a frequ\u00eancia de vibra\u00e7\u00e3o apropriada com base na capacidade de produ\u00e7\u00e3o e na capacidade de processamento do classificador \u00e9 um fator chave para a produ\u00e7\u00e3o eficiente e control\u00e1vel de produtos com distribui\u00e7\u00e3o razo\u00e1vel de tamanho de part\u00edcula. O tamanho da part\u00edcula e a produ\u00e7\u00e3o do produto podem ser ajustados ajustando o n\u00famero de p\u00e1s do impulsor do classificador, a velocidade do impulsor, a press\u00e3o do ar e o volume de ar do ventilador de tiragem induzida e o tamanho do elutriador da grade de ar secund\u00e1ria.<\/p>\n\n\n\n

Prepara\u00e7\u00e3o de p\u00f3 de quartzo ultrafino por moinho a jato<\/h2>\n\n\n\n

A tecnologia de britagem por fluxo de ar \u00e9 uma das mais importantes tecnologias de moagem ultrafina. Guo Xiuping pode obter bons efeitos de britagem usando um leito fluidizado moinho de jato<\/a> para esmagar o quartzo. No separador de ciclone e no coletor de p\u00f3 de saco de pulso, d95 = pode ser obtido, respectivamente. Existem dois produtos: 10\u03bcm e d97=6\u03bcm. Os fatores que afetam o efeito de britagem do material incluem principalmente a corrente de classifica\u00e7\u00e3o, o tamanho das part\u00edculas de alimenta\u00e7\u00e3o e a velocidade de classifica\u00e7\u00e3o.<\/p>\n\n\n\n

Aplica\u00e7\u00e3o de auxiliares de moagem na britagem fina de p\u00f3 de pedra<\/h2>\n\n\n\n

Durante o processo de moagem fina do p\u00f3 de pedra, a adi\u00e7\u00e3o de uma quantidade adequada de auxiliar de moagem n\u00e3o s\u00f3 tem um efeito auxiliar de moagem, mas tamb\u00e9m atua como dispersante. Auxiliares de moagem comuns incluem poliacrilamida, cloreto de s\u00f3dio, silicato, trietanolamina, dodecilsulfonato de s\u00f3dio, etc.
A quantidade de auxiliar de moagem deve ser adequada. Geralmente, \u00e0 medida que a dosagem aumenta, o efeito de moagem aumenta. Ap\u00f3s atingir o valor ideal, aumentar a dosagem piorar\u00e1 o efeito de moagem.<\/p>","protected":false},"excerpt":{"rendered":"
