Ce type de stabilisateur comprend les sels de plomb, les savons m\u00e9talliques acides organiques, les compos\u00e9s organostanniques, les compos\u00e9s \u00e9poxy, les sels de ph\u00e9nol et les sels de thiols m\u00e9talliques. Ils peuvent r\u00e9agir avec le HCL et inhiber la r\u00e9action du PVC avec le HCL.<\/p>\n<p>2) Remplacement des atomes de chlorure d'allyle instables dans la mol\u00e9cule de PVC pour inhiber l'\u00e9limination du PVC, tels que les stabilisateurs organostanniques et les mol\u00e9cules de PVC d'atomes de chlore instables formant une liaison de coordination, dans le ligand, l'organostannique et les atomes de chlore instables sont remplac\u00e9s.<\/p>\n<p>3) R\u00e9action d'addition avec la structure du poly\u00e8ne, destruction de la formation d'un grand syst\u00e8me conjugu\u00e9, r\u00e9duction de la coloration. Les sels ou esters d'acides insatur\u00e9s contiennent des doubles liaisons, et les doubles liaisons conjugu\u00e9es dans la mol\u00e9cule de PVC subissent une r\u00e9action d'addition avec le bis-alc\u00e8ne, d\u00e9truisant ainsi sa structure conjugu\u00e9e et emp\u00eachant le changement de couleur.<\/p>\n<p>4) Capter les radicaux libres et emp\u00eacher la r\u00e9action d'oxydation. Par exemple, l'ajout d'un stabilisateur thermique ph\u00e9nolique peut bloquer le HCL, en raison des radicaux d'atomes d'hydrog\u00e8ne donn\u00e9s par le ph\u00e9nol qui peuvent \u00eatre associ\u00e9s \u00e0 la d\u00e9gradation des radicaux macromol\u00e9culaires du PVC, \u00e0 la formation de substances qui ne peuvent pas r\u00e9agir avec l'O2 et qui ont un effet stabilisateur sur la chaleur. Ce type de stabilisateur thermique peut avoir une ou plusieurs fonctions.<br \/>\nLe stabilisateur thermique id\u00e9al pour le PVC doit \u00eatre un mat\u00e9riau multifonctionnel, ou un m\u00e9lange de certains mat\u00e9riaux, qui peut remplir les fonctions suivantes : Tout d'abord, remplacer le substitut actif, instable ; Deuxi\u00e8mement, l'absorption et la neutralisation de HCL lib\u00e9r\u00e9 pendant le traitement du PVC, l'\u00e9limination de la d\u00e9gradation autocatalytique HCL ; Troisi\u00e8mement, la neutralisation ou la passivation de la d\u00e9gradation de l'effet catalytique des ions m\u00e9talliques et d'autres impuret\u00e9s nocives ; Quatri\u00e8mement, \u00e0 travers le Quatri\u00e8mement, \u00e0 travers une vari\u00e9t\u00e9 de formes de r\u00e9action chimique peut bloquer la liaison insatur\u00e9e continue de cro\u00eetre, d'inhiber la d\u00e9gradation de la coloration ; Cinqui\u00e8mement, il est pr\u00e9f\u00e9rable d'avoir un effet de bouclier protecteur sur la lumi\u00e8re ultraviolette. Habituellement, les stabilisateurs thermiques sont rarement utilis\u00e9s en fonction de leurs performances particuli\u00e8res, et la plupart des vari\u00e9t\u00e9s de poudres, dont certaines sont des substances chimiques tr\u00e8s toxiques. Afin de faciliter l'utilisation, d'\u00e9viter l'empoisonnement par la poussi\u00e8re, de r\u00e9duire les substances toxiques ou de les remplacer par des substances non toxiques, ces derni\u00e8res ann\u00e9es, de nombreux types de stabilisateurs composites ont \u00e9t\u00e9 d\u00e9velopp\u00e9s dans le pays et \u00e0 l'\u00e9tranger, par exemple la s\u00e9rie de stabilisateurs composites allemands Bear de renomm\u00e9e mondiale, les \u00c9tats-Unis, l'Allemagne, le Japon, les Pays-Bas et d'autres pays des stabilisateurs organostanniques ou organostanniques composites, qui ont un march\u00e9 consid\u00e9rable en Chine. Par cons\u00e9quent, promouvoir l'application du d\u00e9veloppement de notre pays avec une efficacit\u00e9 \u00e9lev\u00e9e, un faible co\u00fbt, une absence de pollution par les poussi\u00e8res et une non-toxicit\u00e9 ou une faible toxicit\u00e9 du nouveau stabilisateur composite, est un besoin urgent pour le d\u00e9veloppement de l'industrie plastique de la Chine.<\/p>","protected":false},"excerpt":{"rendered":"<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Nom chimique : Mercaptide d'octyl-\u00e9tain -OTM<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Num\u00e9ro CAS : 26401-97-8<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Formule mol\u00e9culaire : C36H72O4S2Sn<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Poids mol\u00e9culaire : 751,79448<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Aspect : Liquide transparent incolore \u00e0 jaune.<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Teneur en \u00e9tain (%) : 15.5 \u00b1 1<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Aspect : Liquide transparent incolore \u00e0 jaune<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">Emballage : f\u00fbt en plastique en acier de 200 kg ou citerne IBC<\/p>\n<p style=\"margin: 0px 0px 20px; color: #4a4e57; font-family: Roboto;\">\u00c9chantillon : Disponible<\/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.
