Classifica\u00e7\u00e3o dos revestimentos de maquin\u00e1rio de constru\u00e7\u00e3o e os requisitos de desempenho do primer, do meio e do acabamento<\/strong><\/h1>\n

O revestimento de m\u00e1quinas de constru\u00e7\u00e3o \u00e9 uma parte importante do setor de revestimento da China. O revestimento de m\u00e1quinas de constru\u00e7\u00e3o pode ser classificado em primer, revestimento m\u00e9dio e revestimento superior de acordo com a classifica\u00e7\u00e3o do revestimento. O primer \u00e9 o revestimento b\u00e1sico aplicado \u00e0 superf\u00edcie do objeto para a prepara\u00e7\u00e3o. As m\u00e1quinas de constru\u00e7\u00e3o, especialmente as de grande porte, geralmente s\u00e3o operadas ao ar livre, em contato direto com o ar, a umidade, as impurezas e suportam o vento e o sol, parte das condi\u00e7\u00f5es de trabalho da constru\u00e7\u00e3o, a ades\u00e3o do filme de revestimento e a resist\u00eancia \u00e0 corros\u00e3o dependem principalmente do primer. O revestimento intermedi\u00e1rio \u00e9 o revestimento que desempenha o papel de ponte entre o primer e o revestimento superior. Sua principal fun\u00e7\u00e3o \u00e9 preencher o substrato inferior, reparar os defeitos da camada de primer, melhorar a plenitude e o desempenho decorativo do revestimento superior, melhorar a ades\u00e3o do revestimento superior ao revestimento, aumentar a espessura de todo o revestimento e melhorar a resist\u00eancia \u00e0 \u00e1gua e o desempenho anticorrosivo de todo o objeto revestido. Para pe\u00e7as com baixos requisitos decorativos e pe\u00e7as com boa planicidade da superf\u00edcie do substrato, \u00e9 poss\u00edvel reduzir o custo dos produtos de maquin\u00e1rio de constru\u00e7\u00e3o n\u00e3o pulverizando o revestimento intermedi\u00e1rio. O revestimento intermedi\u00e1rio comumente usado \u00e9 o revestimento intermedi\u00e1rio de ep\u00f3xi e o revestimento intermedi\u00e1rio de poliuretano. O revestimento superior \u00e9 a camada mais externa dos produtos de maquin\u00e1rio de constru\u00e7\u00e3o e a apar\u00eancia do produto desempenha um papel fundamental, afetando diretamente os sentidos visuais das pessoas. Atualmente, os tipos de revestimento superior de m\u00e1quinas de constru\u00e7\u00e3o t\u00eam se diversificado.<\/p>\n

O primer \u00e9 o revestimento mais b\u00e1sico no revestimento de maquin\u00e1rio de constru\u00e7\u00e3o e \u00e9 aplicado diretamente na superf\u00edcie do a\u00e7o pr\u00e9-tratado. O primer de revestimento de maquin\u00e1rio de constru\u00e7\u00e3o comumente usado \u00e9 o primer de \u00e9ster ep\u00f3xi, o primer alqu\u00eddico, o primer ep\u00f3xi, o primer acr\u00edlico, o primer de poliuretano e o primer de eletroforese cat\u00f3dica. O primer para constru\u00e7\u00e3o de m\u00e1quinas de constru\u00e7\u00e3o deve ter as seguintes caracter\u00edsticas 1, boa ader\u00eancia ao substrato, para melhorar a ader\u00eancia do primer, muitas vezes adicione um promotor de ader\u00eancia adequado na f\u00f3rmula; 2, na constru\u00e7\u00e3o do filme deve ser formado ap\u00f3s a excelente resist\u00eancia mec\u00e2nica; 3, precisa ter uma boa combina\u00e7\u00e3o da camada superior de tinta. O primer em si tem bom desempenho de constru\u00e7\u00e3o e pode se adaptar a diferentes tipos de processos de revestimento.<\/p>\n

De acordo com os componentes do primer, h\u00e1 o primer de dois componentes e o primer de um componente. O primer de um componente \u00e9 f\u00e1cil de morder o fundo e reduzir a ader\u00eancia na constru\u00e7\u00e3o de revestimentos superiores \u00e0 base de solvente, portanto, o primer ep\u00f3xi de dois componentes se tornou o principal programa de correspond\u00eancia. O primer \u00e9 um pr\u00e9-requisito para a durabilidade e a beleza da camada superior, e o primer bom ou ruim \u00e9 um fator importante que afeta a apar\u00eancia da camada superior. Podemos escolher diferentes tipos de primers mec\u00e2nicos em tr\u00eas aspectos, como desempenho anticorrosivo, desempenho mec\u00e2nico e desempenho de constru\u00e7\u00e3o.<\/p>\n

O revestimento intermedi\u00e1rio \u00e9 o revestimento que desempenha um papel de ponte entre o primer e o revestimento superior. Sua principal fun\u00e7\u00e3o \u00e9 preencher o substrato inferior, isolar os defeitos da camada de primer, a fim de melhorar a plenitude do revestimento superior e outras propriedades decorativas, ao mesmo tempo em que melhora a ades\u00e3o do revestimento superior ao revestimento, aumenta a espessura de todo o revestimento correspondente e melhora a resist\u00eancia \u00e0 \u00e1gua e as propriedades anticorrosivas de todo o objeto revestido. Os requisitos do maquin\u00e1rio de engenharia para o revestimento intermedi\u00e1rio s\u00e3o 1, boa compatibilidade com o primer e o acabamento, forte liga\u00e7\u00e3o com os revestimentos superior e inferior; 2, a dureza do revestimento \u00e9 moderada, o solvente do acabamento n\u00e3o pode \"morder\" esse revestimento, a resist\u00eancia \u00e0 \u00e1gua e \u00e0 umidade deve ser boa, n\u00e3o causar\u00e1 bolhas no acabamento; o desempenho do lixamento deve ser bom, pode ser seco a uma temperatura alta adequada, boa secagem. A tinta de revestimento intermedi\u00e1rio comumente usada tem revestimento intermedi\u00e1rio de ep\u00f3xi e revestimento intermedi\u00e1rio de poliuretano; o revestimento intermedi\u00e1rio de poliuretano tem melhor desempenho contra intemp\u00e9ries.<\/p>\n

A camada de acabamento pode deixar o maquin\u00e1rio de constru\u00e7\u00e3o com alto brilho, cores vibrantes e dar uma sensa\u00e7\u00e3o de beleza. O efeito da camada superior afeta diretamente o julgamento do cliente sobre os produtos de maquin\u00e1rio de constru\u00e7\u00e3o bons ou ruins, portanto, a apar\u00eancia da cor e do efeito \u00e9 cada vez mais importante. Os acabamentos \u00e0 base de solvente comumente usados s\u00e3o alqu\u00eddicos, acr\u00edlicos, de borracha clorada e de poliuretano. Os requisitos do acabamento de m\u00e1quinas de constru\u00e7\u00e3o se refletem principalmente no desempenho da prote\u00e7\u00e3o, no desempenho decorativo, no desempenho da constru\u00e7\u00e3o etc., respectivamente, e s\u00e3o descritos resumidamente a seguir.<\/p>\n

As m\u00e1quinas de constru\u00e7\u00e3o geralmente s\u00e3o constru\u00eddas e armazenadas ao ar livre, e as condi\u00e7\u00f5es de trabalho s\u00e3o adversas, enfrentando o vento e o sol, a polui\u00e7\u00e3o por poeira, a lama da chuva e a lavagem com \u00e1gua. Portanto, o maquin\u00e1rio de constru\u00e7\u00e3o precisa ser revestido com uma certa espessura de filme de revestimento para isolar o oxig\u00eanio, a \u00e1gua, a poeira e outras subst\u00e2ncias corrosivas na atmosfera, para proteger contra a corros\u00e3o dentro de um determinado per\u00edodo de tempo e para garantir a vida \u00fatil do equipamento. A fun\u00e7\u00e3o de prote\u00e7\u00e3o \u00e9 a fun\u00e7\u00e3o b\u00e1sica do revestimento de maquin\u00e1rio de constru\u00e7\u00e3o, que exige um revestimento com boa ader\u00eancia, resist\u00eancia ao impacto, flexibilidade e outras propriedades mec\u00e2nicas.<\/p>\n

A apar\u00eancia do revestimento \u00e9 um fator importante na competitividade dos produtos de maquin\u00e1rio de constru\u00e7\u00e3o, com maior brilho, maior plenitude, esquema de cores de revestimento agrad\u00e1vel, naturalmente mais f\u00e1cil de conquistar o mercado. Al\u00e9m disso, com o desenvolvimento do mercado, as empresas de maquin\u00e1rio de constru\u00e7\u00e3o est\u00e3o cientes da import\u00e2ncia da constru\u00e7\u00e3o da marca e da identidade visual da imagem corporativa (VI), de modo que o revestimento superior tamb\u00e9m desempenhar\u00e1 um papel importante na comunica\u00e7\u00e3o da marca. O maquin\u00e1rio de constru\u00e7\u00e3o como um todo tem uma estrutura enorme e complexa, e \u00e9 dif\u00edcil conseguir que a superf\u00edcie de revestimento de todas as pe\u00e7as tenha um efeito de alta apar\u00eancia. Por esse motivo, o setor de m\u00e1quinas de constru\u00e7\u00e3o apresentou o conceito de pe\u00e7as de revestimento, ou seja, pe\u00e7as que cobrem a parte externa da m\u00e1quina e do equipamento, incluindo tanques de combust\u00edvel, cabines, tampas de motor, tampas etc. Nessas pe\u00e7as de revestimento, o foco \u00e9 destacar a natureza decorativa do revestimento, exigindo que a pel\u00edcula de revestimento da superf\u00edcie seja lisa, uniforme, completa, de alto brilho, sem inconvenientes, e tenha um certo grau de resist\u00eancia a intemp\u00e9ries, em um determinado per\u00edodo de tempo, sua perda de luz e desbotamento estejam dentro da faixa especificada. Portanto, os absorvedores de UV e outros produtos fotoestabilizadores t\u00eam aplica\u00e7\u00f5es importantes em revestimentos de maquin\u00e1rio de constru\u00e7\u00e3o.<\/p>\n

Na sele\u00e7\u00e3o da camada superior do maquin\u00e1rio de constru\u00e7\u00e3o, \u00e9 preciso prestar aten\u00e7\u00e3o a ela e ao primer, \u00e0 tinta ou \u00e0 massa de vidraceiro, caso contr\u00e1rio, o revestimento poder\u00e1 ficar todo enrugado e morder a parte inferior, al\u00e9m de outros fen\u00f4menos ruins de suporte. O revestimento superior requer bom nivelamento, alto brilho, alto brilho e boa plenitude, mas n\u00e3o deve ser suspenso. No caso de desempenho ruim de nivelamento da camada superior, isso pode levar a desvantagens como enforcamento, casca de laranja, pouco frescor e pouco preenchimento.<\/p>\n
