Esse tipo de estabilizador inclui sais de chumbo, sab\u00e3o met\u00e1lico de \u00e1cido org\u00e2nico, compostos de organoestanho, compostos de ep\u00f3xi, sais de fenol e sais de tiol met\u00e1lico. Eles podem reagir com o HCL e inibir a rea\u00e7\u00e3o do PVC com o HCL.<\/p>\n<p>2) Substitui\u00e7\u00e3o de \u00e1tomos inst\u00e1veis de cloreto de alila na mol\u00e9cula de PVC para inibir a remo\u00e7\u00e3o de PVC, como estabilizadores de organoestanho e mol\u00e9culas de PVC de \u00e1tomos de cloro inst\u00e1veis que ocorrem na liga\u00e7\u00e3o de coordena\u00e7\u00e3o, no ligante, organoestanho e \u00e1tomos de cloro inst\u00e1veis s\u00e3o substitu\u00eddos.<\/p>\n<p>3) Rea\u00e7\u00e3o de adi\u00e7\u00e3o com a estrutura do polieno, destr\u00f3i a forma\u00e7\u00e3o de um grande sistema conjugado e reduz a colora\u00e7\u00e3o. Os sais ou \u00e9steres de \u00e1cidos insaturados cont\u00eam liga\u00e7\u00f5es duplas, e as liga\u00e7\u00f5es duplas conjugadas na mol\u00e9cula de PVC sofrem uma rea\u00e7\u00e3o de adi\u00e7\u00e3o de bis-alceno, destruindo assim sua estrutura conjugada e inibindo a mudan\u00e7a de cor.<\/p>\n<p>4) Captura de radicais livres e evita a rea\u00e7\u00e3o de oxida\u00e7\u00e3o. Por exemplo, a adi\u00e7\u00e3o de estabilizador de calor fen\u00f3lico pode bloquear o HCL, devido ao fato de que os radicais de \u00e1tomo de H do fenol podem ser acoplados \u00e0 degrada\u00e7\u00e3o dos radicais macromoleculares de PVC, \u00e0 forma\u00e7\u00e3o de subst\u00e2ncias que n\u00e3o podem reagir com o O2 e t\u00eam um efeito estabilizador de calor. Esse tipo de estabilizador de calor pode ter uma ou v\u00e1rias fun\u00e7\u00f5es.<br \/>\nO estabilizador de calor de PVC ideal deve ser um material multifuncional, ou uma mistura de alguns materiais, que possa desempenhar as seguintes fun\u00e7\u00f5es: Primeiro, substituir o substituinte ativo e inst\u00e1vel; Segundo, absor\u00e7\u00e3o e neutraliza\u00e7\u00e3o do HCL liberado durante o processamento do PVC, eliminando a degrada\u00e7\u00e3o autocatal\u00edtica do HCL; Terceiro, neutraliza\u00e7\u00e3o ou passiva\u00e7\u00e3o da degrada\u00e7\u00e3o do efeito catal\u00edtico de \u00edons met\u00e1licos e outras impurezas nocivas; Quarto, por meio de uma variedade de formas de rea\u00e7\u00e3o qu\u00edmica, pode bloquear a liga\u00e7\u00e3o insaturada que continua a crescer, inibindo a degrada\u00e7\u00e3o da colora\u00e7\u00e3o; Quinto, \u00e9 melhor ter um efeito de blindagem protetora na luz ultravioleta. Normalmente, os estabilizadores de calor, de acordo com seu desempenho especial, s\u00e3o raros, com o uso de casos separados, e a maioria das variedades de p\u00f3, alguns s\u00e3o subst\u00e2ncias qu\u00edmicas muito t\u00f3xicas. Para facilitar o uso, evitar o envenenamento por poeira, reduzir as subst\u00e2ncias t\u00f3xicas ou substitu\u00ed-las por subst\u00e2ncias n\u00e3o t\u00f3xicas, nos \u00faltimos anos, muitos tipos de estabilizadores compostos foram desenvolvidos no pa\u00eds e no exterior, por exemplo, a mundialmente famosa s\u00e9rie de estabilizadores compostos German Bear, os Estados Unidos, a Alemanha, o Jap\u00e3o, a Holanda e outros pa\u00edses dos estabilizadores de organoestanho ou organoestanho composto t\u00eam um mercado consider\u00e1vel na China. Portanto, promover a aplica\u00e7\u00e3o do desenvolvimento do nosso pa\u00eds com alta efici\u00eancia, baixo custo, sem polui\u00e7\u00e3o de poeira e n\u00e3o t\u00f3xico ou com baixa toxicidade do novo estabilizador composto \u00e9 a necessidade urgente para o desenvolvimento do setor de pl\u00e1sticos da China.<\/p>","protected":false},"excerpt":{"rendered":"<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Nome qu\u00edmico: Octyl Tin Mercaptide -OTM<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">N\u00famero CAS: 26401-97-8<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">F\u00f3rmula molecular: C36H72O4S2Sn<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Peso molecular: 751,79448<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Apar\u00eancia: L\u00edquido transparente incolor a amarelo.<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Teor de estanho (%): 15.5 \u00b1 1<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Apar\u00eancia: L\u00edquido transparente incolor a amarelo<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Embalagem: tambor pl\u00e1stico de a\u00e7o de 200 kg ou tanque IBC<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Amostra: Dispon\u00edvel<\/p>","protected":false},"featured_media":6932,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[113],"product_tag":[],"class_list":{"0":"post-6909","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-organic-intermediate","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v25.3.1 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>China Manufacturer Octyl tin mercaptide-Otm cas 26401-97-8 -Longchang Chemical<\/title>\n<meta name=\"description\" content=\"PVC Heat Stabilizer\/Octyl Tin Mercaptide cas 26401-97-8 is key product of LongChang Chemical.
