<\/span>Aplica\u00e7\u00e3o do PSA de Silicone<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/h2>\n

Em detalhe, comparado a outros tipos de adesivos sens\u00edveis \u00e0 press\u00e3o, os adesivos sens\u00edveis \u00e0 press\u00e3o de silicone possuem as seguintes propriedades e aplica\u00e7\u00f5es.<\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>Primeiro<\/span><\/b><\/span><\/span><\/span><\/span><\/span><\/h3>\n

1. Resist\u00eancia ao desempenho em altas e baixas temperaturas (os \u00fanicos adesivos org\u00e2nicos que podem ser utilizados na ampla faixa de temperatura de -65 a 300\u00b0C)<\/span><\/span><\/span><\/span><\/span><\/p>\n

2. Boa resist\u00eancia \u00e0s intemp\u00e9ries<\/span><\/span><\/span><\/span><\/span><\/p>\n

3. Alta ades\u00e3o por arrancamento em interfaces de baixa energia superficial (Teflon, borracha de silicone)<\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

Portanto, o adesivo sens\u00edvel \u00e0 press\u00e3o de silicone pode ser utilizado como fita de alta temperatura, fita de baixa temperatura e para a ades\u00e3o de materiais de baixa energia superficial, como teclas de borracha de silicone.<\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>Segundo<\/font><\/span><\/b><\/span><\/span><\/span><\/span><\/span><\/h3>\n

1. Propriedades el\u00e9tricas excelentes<\/span><\/span><\/span><\/span><\/span><\/p>\n

5. Excelentes propriedades de nivelamento<\/span><\/span><\/span><\/span><\/span><\/p>\n

6. Res\u00edduo baixo na superf\u00edcie do objeto a ser colado<\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

<\/a>Os PSA de silicone podem, portanto, ser utilizados como pel\u00edculas protetoras para telas eletr\u00f3nicas e vidros automotivos. Esta \u00e9 atualmente a \u00e1rea mais amplamente utilizada e pesquisada de adesivos sens\u00edveis \u00e0 press\u00e3o de silicone.<\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/p>\n

<\/span>M\u00e9todo de cura do adesivo sens\u00edvel \u00e0 press\u00e3o de silicone<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/h2>\n

 <\/p>\n

De acordo com o m\u00e9todo de vulcaniza\u00e7\u00e3o, os adesivos sens\u00edveis \u00e0 press\u00e3o de silicone dividem-se principalmente em tr\u00eas tipos: tipo de vulcaniza\u00e7\u00e3o com per\u00f3xido, tipo de vulcaniza\u00e7\u00e3o por adi\u00e7\u00e3o e tipo de cura por luz UV. <\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

Al\u00e9m disso, adesivos sens\u00edveis \u00e0 press\u00e3o de silicone como cura por radia\u00e7\u00e3o de feixe de eletr\u00f5es e vulcaniza\u00e7\u00e3o \u00e0 temperatura ambiente tamb\u00e9m est\u00e3o em desenvolvimento cont\u00ednuo.<\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

<\/a>As caracter\u00edsticas respetivas do PSA de silicone com diferentes m\u00e9todos de vulcaniza\u00e7\u00e3o s\u00e3o as seguintes.<\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>1. PSA de silicone vulcanizado com per\u00f3xido de benzo\u00edla (BPO)<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/h3>\n

Tem uma temperatura de vulcaniza\u00e7\u00e3o elevada (150\u00b0C) e uma velocidade de vulcaniza\u00e7\u00e3o lenta, pelo que este tipo de adesivo sens\u00edvel \u00e0 press\u00e3o n\u00e3o \u00e9 adequado para substratos com baixa resist\u00eancia \u00e0 temperatura. <\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

<\/span>2. PSA de silicone por vulcaniza\u00e7\u00e3o por adi\u00e7\u00e3o<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/h3>\n

Caracteriza-se principalmente por baixa temperatura de vulcaniza\u00e7\u00e3o (100-130\u00b0C), velocidade de cura r\u00e1pida e nenhum subproduto durante o processo de rea\u00e7\u00e3o, podendo assim ser aplicado a substratos com baixa resist\u00eancia \u00e0 temperatura, sendo principalmente utilizado em pel\u00edculas protetoras. <\/span><\/span><\/span><\/span><\/span><\/p>\n

 <\/p>\n

However, since the addition vulcanization silicone adhesives are catalyzed by the platinum catalyst, this type of catalyst encounters organic compounds containing N, P, S and other elements and ionic compounds containing Sn, Pb, Hg, Bi, As and other metals May be \u201cpoisoned\u201d and inactivated, so avoid contact with these substances during production, transportation, and use.<\/span><\/span><\/span><\/span><\/span><\/p>\n

<\/span>3. PSA de silicone de cura por luz UV<\/span><\/span><\/b><\/span><\/span><\/span><\/span><\/h3>\n

\u00c9 um novo tipo de sistema de adesivo sens\u00edvel \u00e0 press\u00e3o. N\u00e3o cont\u00e9m ou cont\u00e9m uma quantidade muito pequena de solvente. N\u00e3o tem polui\u00e7\u00e3o, baixo consumo de energia e alta efici\u00eancia. Pode satisfazer o uso de alguns substratos que s\u00e3o muito sens\u00edveis \u00e0 temperatura. <\/span><\/span><\/span><\/span><\/span><\/p>\n

Devido ao custo elevado e tecnologia relativamente imatura, este tipo de adesivo sens\u00edvel \u00e0 press\u00e3o de silicone ainda n\u00e3o foi geralmente aceite pelo mercado, mas \u00e0 medida que a <\/a>most important trend of silicone pressure-sensitive adhesive in the future, it has attracted more and more researchers\u2019 attention.<\/span><\/span><\/span><\/span><\/span><\/p>\n

Para alguns substratos resistentes a altas temperaturas, este tipo de adesivo sens\u00edvel \u00e0 press\u00e3o de silicone pode ser utilizado, como a fita resistente a altas temperaturas baseada em <\/a>pel\u00edcula de poliimida (PI), comumente conhecida como fita de dedo de ouro, que \u00e9 um adesivo sens\u00edvel \u00e0 press\u00e3o de silicone vulcanizado uniformemente com BPO. \u00c9 produzido por revestimento no substrato resistente a altas temperaturas de pel\u00edcula de PI.<\/span><\/span><\/span><\/span><\/span><\/p>\n

O adesivo sens\u00edvel \u00e0 press\u00e3o de silicone \u00e9 composto principalmente por borracha de silicone e resina MQ. A borracha de silicone \u00e9 a subst\u00e2ncia formadora de filme do adesivo sens\u00edvel \u00e0 press\u00e3o de silicone <\/a>adhesive. It has a large molecular weight and provides high enough cohesive strength for silicone pressure-sensitive adhesive. MQ silicone resin has a spherical \u201ccore-shell structure\u201d and is the bonding component of silicone pressure-sensitive adhesives.<\/span><\/span><\/span><\/span><\/span><\/p>\n
