Rompe o gargalo do processo! A combinação de ouro de silicone de adição de um componente e vulcanizador de platina com um componente

▶ Traditional addition-type liquid rubber and addition-type compound rubber are generally AB two-component, in which the A component generally contains base rubber and platinum catalyst, and the B component contains base rubber, hydrogen silicone oil crosslinking agent and inhibitor and other additives. During use, it is necessary to accurately measure according to the ratio (mostly 1:1, but also 10:1 or other ratios), and the AB components must be evenly mixed in static mixers, blenders, open mills and other mixing equipment before use. This not only increases the equipment investment cost, but also increases the process cost, labor cost, and storage cost, which brings some inconvenience to the end-user's batch industrial production. And generally, after the AB components are evenly mixed, the room temperature storage time is curto . Geralmente, depois de ser colocado por algumas horas a uma semana, a fluidez será gradualmente perdida e até a borracha morta perderá seu valor de uso .

▶ For some special purposes (such as CIPG/FIPG, food grade, medical grade, clothing printing, glass fiber coating, etc.), adding liquid glue and compound glue into a single component ready-to-use type can reduce the user's mismatch in the production process, ensure product quality, and improve the production efficiency of end users, prolong the operation time, thereby greatly improving the technical added value of the cola .

▶ O principal método de moldagem de vulcanização principal para o composto de borracha de silicone foi a vulcanização de peróxido, como o uso de di-2- tetra-vulcanizer para silicone extrudado e diaberdons de proteção e de proteção do meio do ambiente e do.}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}. tornou -se o mainstream do desenvolvimento de produtos e tecnologia .

Comparado com o sistema de peróxido tradicional, os produtos de silicone com platina têm as seguintes características: sem subprodutos durante o processo de cura, sem odor, alta transparência, alta resistência amarelada, mais fácil de passar alimentos e testes de grau médico, ° de cura »» {de maneira fáceis de usar ° C, »» »» »» de ° de cura »» »» »{de maneira fáceis de usar ° C,« da tecnologia de cura de platina e o declínio gradual nos custos de platina, as vantagens da cura de platina sobre a cura de peróxido estão se tornando cada vez mais óbvias, e os agentes de cura de platina estão gradualmente se tornando o mainstream no mercado .

Traditional platinum vulcanizers are generally divided into two components, A and B, where A is the platinum component and B is the hydrogen-containing component. During use, customers need to first add component B and mix evenly on the open mill, and then add component A and mix evenly. The first batch of materials needs to be mixed twice, which has high labor intensity and low production eficiência .

Through the adjustment of formula and process, the platinum component and the hydrogen-containing and inhibitor components are organically combined to produce a single-component platinum vulcanizer. Compared with the two-component product, the single-component product has a higher content of effective ingredients, resulting in a small total addition amount, low cost, easy use and high production efficiency. In some products and applications, the O custo abrangente do vulcanizador de platina de componente único é ainda menor que o do vulcanizador peróxido .

Therefore, in recent years, single-component platinum vulcanizers have been increasingly used, and the added value of the product is higher than that of traditional peroxide vulcanizers and two-component platinum vulcanizers. However, the disadvantage is that the storage time is still not long enough and the formula is relatively complicated.

▶ The traditional method is to add hydrogen silicone oil, inhibitor and platinum catalyst to the base rubber and mix them, but the disadvantage of this is that the operation time is short and the rubber is prone to dead. The usual technical idea is to increase the dosage of inhibitors, or to use special new inhibitors with long room temperature operation time, but this will bring about the problem of too slow vulcanization speed, so you tem que adicionar mais catalisador de platina ao mesmo tempo, mas isso trará o problema de alto custo, e o tempo de armazenamento à temperatura ambiente ainda não é satisfatório e geralmente precisa ser armazenado em um freezer .}
