Dependendo do tamanho das part\u00edculas do min\u00e9rio e de sua distribui\u00e7\u00e3o na polpa, classificamos a polpa em tr\u00eas tipos: homog\u00eanea, quase homog\u00eanea e n\u00e3o homog\u00eanea. A pasta homog\u00eanea refere-se a uma suspens\u00e3o de part\u00edculas s\u00f3lidas uniformemente dispersas em um \u00fanico fluido, normalmente com part\u00edculas menores que 0,25 mm, que podem se misturar bem com \u00e1gua e aderir \u00e0s leis de din\u00e2mica de fluidos. Para part\u00edculas maiores que 0,25 mm, no fluxo horizontal, a gravidade provoca maior concentra\u00e7\u00e3o de part\u00edculas no fundo do tubo, o que pode levar \u00e0 sedimenta\u00e7\u00e3o.

Quando o tamanho da part\u00edcula \u00e9 inferior a 0,05 mm, o desgaste na tubula\u00e7\u00e3o \u00e9 m\u00ednimo. No entanto, \u00e0 medida que o tamanho das part\u00edculas aumenta entre 0,05 mm e 0,5 mm, o desgaste na tubula\u00e7\u00e3o tamb\u00e9m aumenta. Para part\u00edculas maiores que 0,5 mm, o desgaste na tubula\u00e7\u00e3o torna-se significativo. Da mesma forma, quando a concentra\u00e7\u00e3o de part\u00edculas na lama \u00e9 inferior a 1%, a probabilidade de as part\u00edculas colidirem com a parede do tubo \u00e9 muito baixa, resultando em desgaste m\u00ednimo. Mas \u00e0 medida que a concentra\u00e7\u00e3o de part\u00edculas aumenta, o desgaste do tubo tamb\u00e9m aumenta. Maior dureza do min\u00e9rio leva a um desgaste mais r\u00e1pido das conex\u00f5es dos tubos. Al\u00e9m disso, se o min\u00e9rio tiver alta densidade, ele assenta rapidamente, dificultando a manuten\u00e7\u00e3o de uma suspens\u00e3o uniforme e agravando o desgaste na parte inferior do mineroduto.<\/li>\n\n\n\n<li><strong>Desgaste Corrosivo: <\/strong>As conex\u00f5es para tubos podem sofrer corros\u00e3o eletroqu\u00edmica e corros\u00e3o.

A presen\u00e7a de sulfetos como pirita e marcassita na lama transportada pode acelerar a corros\u00e3o dos tubos. Em tubula\u00e7\u00f5es longas com declives acentuados, mudan\u00e7as abruptas na altura da tubula\u00e7\u00e3o podem criar v\u00e1cuo localizado e press\u00e3o positiva quando a lama sobe e desce, causando danos por corros\u00e3o nas conex\u00f5es da tubula\u00e7\u00e3o.<\/li>\n<\/ol>\n<\/div><\/div>\n\n\n<style>.kadence-column1399_34098e-c4 > .kt-inside-inner-col,.kadence-column1399_34098e-c4 > .kt-inside-inner-col:before{border-top-left-radius:0px;border-top-right-radius:0px;border-bottom-right-radius:0px;border-bottom-left-radius:0px;}.kadence-column1399_34098e-c4 > .kt-inside-inner-col{column-gap:var(--global-kb-gap-sm, 1rem);}.kadence-column1399_34098e-c4 > .kt-inside-inner-col{flex-direction:column;}.kadence-column1399_34098e-c4 > .kt-inside-inner-col > .aligncenter{width:100%;}.kadence-column1399_34098e-c4 > .kt-inside-inner-col:before{opacity:0.3;}.kadence-column1399_34098e-c4{position:relative;}@media all and (max-width: 1024px){.kadence-column1399_34098e-c4 > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}@media all and (max-width: 767px){.kadence-column1399_34098e-c4 > .kt-inside-inner-col{flex-direction:column;justify-content:center;}}<\/style>\n<div class=\"wp-block-kadence-column kadence-column1399_34098e-c4\"><div class=\"kt-inside-inner-col\"><style>.wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a, .wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a[data-kb-block=\"kb-adv-heading1399_cb6d79-9a\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a[data-kb-block=\"kb-adv-heading1399_cb6d79-9a\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading1399_cb6d79-9a[data-kb-block=\"kb-adv-heading1399_cb6d79-9a\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<h3 class=\"kt-adv-heading1399_cb6d79-9a wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading1399_cb6d79-9a\">M\u00e9todos para aliviar o desgaste do tubo:<\/h3>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c, .wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c[data-kb-block=\"kb-adv-heading1399_e426e0-7c\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c[data-kb-block=\"kb-adv-heading1399_e426e0-7c\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading1399_e426e0-7c[data-kb-block=\"kb-adv-heading1399_e426e0-7c\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<p class=\"kt-adv-heading1399_e426e0-7c wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading1399_e426e0-7c\">Depois de analisar as principais causas do desgaste das conex\u00f5es de tubos, quais s\u00e3o algumas maneiras eficazes de mitigar esse problema? Com base na experi\u00eancia pr\u00e1tica, a DEF Rubber compilou alguns m\u00e9todos. Claro, estamos abertos a suas sugest\u00f5es e ansiosos para discutir mais:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Use materiais avan\u00e7ados resistentes ao desgaste: <\/strong>Para melhorar o desgaste das conex\u00f5es de tubos e a resist\u00eancia \u00e0 corros\u00e3o, considere o uso de materiais avan\u00e7ados resistentes ao desgaste, como revestimento de borracha resistente ao desgaste, poliuretano ou pedra fundida. O revestimento de borracha resistente ao desgaste, em particular, provou ser altamente eficaz. A DEF Rubber desenvolveu revestimento de borracha resistente ao desgaste com \u00edndices de desgaste superiores a 130% e taxas de recupera\u00e7\u00e3o superiores a 80%. Ele encontra ampla aplica\u00e7\u00e3o em m\u00e1quinas de minera\u00e7\u00e3o e acess\u00f3rios para tubos, reduzindo significativamente o desgaste e prolongando a vida \u00fatil dos acess\u00f3rios. Os materiais de poliuretano s\u00e3o mais caros e oferecem menor resist\u00eancia ao desgaste em compara\u00e7\u00e3o com o revestimento de borracha resistente ao desgaste. A pedra fundida tamb\u00e9m \u00e9 um material resistente ao desgaste popular para acess\u00f3rios de tubos, normalmente usado como revestimento interno de tubos de a\u00e7o, protegendo o tubo do desgaste. No entanto, os acess\u00f3rios de pedra fundida s\u00e3o mais dif\u00edceis de construir e manter do que o revestimento de borracha resistente ao desgaste, devido ao seu peso significativo.<\/li>\n\n\n\n<li><strong>Aumentar a concentra\u00e7\u00e3o de pasta: <\/strong>Manter a concentra\u00e7\u00e3o da pasta dentro da faixa de \u201cconcentra\u00e7\u00e3o cr\u00edtica\u201d durante o transporte \u00e9 essencial. A concentra\u00e7\u00e3o cr\u00edtica \u00e9 um intervalo, e n\u00e3o um valor espec\u00edfico, pois flutua com base em fatores como volume de lama e tamanho de part\u00edcula s\u00f3lida. Na \u201cregi\u00e3o de arrasto reduzido\u201d dentro desta faixa, uma maior concentra\u00e7\u00e3o de lama reduz a taxa de fluxo cr\u00edtica. Isso ajuda a evitar que min\u00e9rio grosso, afiado e duro se acumule no fundo do tubo, reduzindo o desgaste concentrado e prolongando a vida \u00fatil da conex\u00e3o do tubo. Al\u00e9m disso, uma maior concentra\u00e7\u00e3o de chorume conserva \u00e1gua e energia.<\/li>\n\n\n\n<li><strong>Pr\u00e9-Separa\u00e7\u00e3o de Part\u00edculas de Min\u00e9rio Grosso:<\/strong> No transporte de rejeitos, uma por\u00e7\u00e3o significativa das part\u00edculas de min\u00e9rio consiste em part\u00edculas de 0,2 a 0,5 mm e algumas maiores que 0,5 mm. Estas part\u00edculas contribuem para um maior desgaste dos tubos. Para reduzir o desgaste, considere classificar a polpa antes que ela entre na tubula\u00e7\u00e3o para remover part\u00edculas maiores de min\u00e9rio, minimizando assim o desgaste.<\/li>\n\n\n\n<li><strong>Mitigar o desgaste corrosivo:<\/strong> Para reduzir o desgaste das conex\u00f5es do tubo devido \u00e0 corros\u00e3o eletroqu\u00edmica, considere tr\u00eas m\u00e9todos principais: (1) Controlar o potencial do eletrodo atrav\u00e9s de prote\u00e7\u00e3o an\u00f3dica ou cat\u00f3dica. (2) Adicionar inibidores de corros\u00e3o \u00e0 pasta. Esses inibidores podem ser inibidores an\u00f3dicos, cat\u00f3dicos ou mistos, cada um impactando diferentes aspectos da corros\u00e3o. (3) Aplica\u00e7\u00e3o de revestimentos protetores nas conex\u00f5es dos tubos. Revestimentos n\u00e3o met\u00e1licos, como tinta com chumbo vermelho e tinta de resina alqu\u00eddica, podem isolar com efic\u00e1cia elementos corrosivos.<\/li>\n\n\n\n<li><strong>Manuten\u00e7\u00e3o:<\/strong> Inspecione regularmente o desgaste das conex\u00f5es do tubo, repare quaisquer revestimentos danificados e vire ou mude periodicamente a dire\u00e7\u00e3o do tubo para garantir um desgaste uniforme nas conex\u00f5es.<\/li>\n<\/ol>\n\n\n<style>.wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77, .wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77[data-kb-block=\"kb-adv-heading1399_c665a6-77\"]{font-style:normal;}.wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77 mark.kt-highlight, .wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77[data-kb-block=\"kb-adv-heading1399_c665a6-77\"] mark.kt-highlight{font-style:normal;color:#f76a0c;-webkit-box-decoration-break:clone;box-decoration-break:clone;padding-top:0px;padding-right:0px;padding-bottom:0px;padding-left:0px;}.wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77 img.kb-inline-image, .wp-block-kadence-advancedheading.kt-adv-heading1399_c665a6-77[data-kb-block=\"kb-adv-heading1399_c665a6-77\"] img.kb-inline-image{width:150px;vertical-align:baseline;}<\/style>\n<p class=\"kt-adv-heading1399_c665a6-77 wp-block-kadence-advancedheading\" data-kb-block=\"kb-adv-heading1399_c665a6-77\">O desgaste e a corros\u00e3o das conex\u00f5es de tubos s\u00e3o quest\u00f5es complexas e a abordagem para mitig\u00e1-los pode variar de empresa para empresa.
