Teste de Dureza de Arranhões
Scratch Hardness Tester LINEARTESTER 249 Smart
O testador de dureza de arranhões optimizado LINEARTESTER 249 Smart destina-se, para além da sua finalidade original de aplicação, ou seja, a estabelecer a capacidade de uma superfície resistir a danos por arranhões, também para vários outros testes: Testes de escrição/riscadura; testes de abrasão por abrasão de ciclo; testes de Crockmeter; testes MEK; testes que determinam a resistência contra solventes em geral ou teste de limpeza, respectivamente.
O LINEARTESTER 249 Smart é um dispositivo de mesa que é operado através de um visor LCD capacitivo. A unidade electromotriz assegura um movimento uniforme de avanço da lâmina. A ferramenta de teste é baixada e levantada automaticamente quando são efectuados testes de raspagem/escritura. Estão disponíveis várias ferramentas de teste diferentes (ver tabela na descrição técnica abaixo). As ferramentas marcadas com (*) são feitas de Carboneto de Tungsténio, adicionalmente cobertas com uma camada extremamente dura. Devido ao aspecto "dourado" desta camada, quaisquer peças desgastadas são visualmente muito fáceis de reconhecer porque o Material de Carboneto de Tungsténio sob a camada "dourada" tem uma cor distintamente diferente. Com o conjunto adaptador universal opcional disponível (ver última página da descrição técnica), até mesmo várias inserções de ferramentas específicas do utilizador podem.
Princípio do Teste: O painel de teste é fixado a uma corrediça móvel por meio de calhas de fixação. Acima desta corrediça e fixada sobre dois pilares metálicos é um leito de feixe recíproco, com movimento livre e com a ferramenta de teste adequada, bem como um peso. A força de raspagem necessária na gama de (0,5 a 20)N é definida movendo o peso ao longo da viga recíproca, fazendo uso de uma escala de ajuste (um peso de carga adicional de (1 a 40)N está opcionalmente disponível). A máquina de ensaio está equipada com um dispositivo de braço de carga ajustável em altura de 4 posições com altura padrão de cerca de 10 mm (+20/+40/+60 mm). Para utilizar o ajuste vertical, é também necessário um conjunto de peças de fixação de amostras (Despacho n.º 21010232). O funcionamento (ajustes) é efectuado através de um visor LCD capacitivo. Para iniciar um teste de raspagem, a ferramenta de teste é baixada sobre a amostra quando se avança para o início imediato do processo de raspagem. O painel de teste pode ser deslocado lateralmente para que uma série de arranhões possa ser efectuada lado a lado com diferentes configurações de força. Devido a uma régua integrada na placa de deslizamento, uma distância uniforme entre os riscos pode ser alcançada muito facilmente. Ao testar os revestimentos isolantes em substratos condutores, um reconhecimento eléctrico do riscamento transversal oferece uma segurança adicional para a regulação da força de arranhadura. Para testes de abrasão, testes de crockmeter, MEK ou testes de limpeza, o movimento de teste é realizado com a ferramenta baixada sobre a amostra, em ciclos pré-definidos de e para. Para isso, a placa guia tem de ser removida da placa deslizante. As velocidades de ensaio são livremente ajustáveis. O LINEARTESTER Smart está equipado com com comprimentos de curso variáveis.
