The phenolic hydroxyl group in phenolic antioxidants can release active hydrogen to capture the \u2018key offender\u2019 free radicals in polymer degradation. Natural products such as VE, tea polyphenols, and low molecular compounds such as 2,6-di-tert-butylphenol (BHT) are phenolic antioxidants. Hindered phenolic antioxidants are a class of compounds with substituents on one or both sides of the hydroxyl group (-OH) on the benzene ring. Because the hydroxyl group is spatially hindered, the H atom is easily dislodged from the molecule with peroxyl radicals (ROO .) , alkoxyl radicals (RO.), hydroxyl radicals (.OH), etc. to combine to make them inactive, thus terminating the chain reaction of thermo-oxidative aging. Hindered phenolic antioxidants are non-polluting products and are suitable for colourless or light-coloured products. Moreover, hindered phenolic antioxidants have large molecular weight, good compatibility with polymer materials and low toxicity, so the consumption ratio of high molecular weight hindered phenolic varieties represented by <a href=\"https:\/\/changhongchemical.com\/product\/chlumiao-1010-cas-6683-19-8\/\">1010<\/a> and 1076 increases year by year, while 1010 becomes the most excellent product among polymer antioxidants with high molecular weight, good compatibility with polymer materials, excellent antioxidant effect, good safety, and the largest consumption.<br \/>\n(2) Antiossidanti a base di fosfito<br \/>\nIl ruolo principale dell'antiossidante fosfito \u00e8 quello di rimuovere gli idroperossidi; non solo la degradazione del polimero produce idroperossidi, ma anche l'antiossidante principale, per inibire l'aggiunta di idroperossidi, produce idroperossidi. Pertanto, come antiossidante ausiliario, gli antiossidanti fosfatici non sono molto efficaci se usati da soli, ma hanno un effetto significativo se usati insieme all'antiossidante principale. Il prodotto rappresentativo dell'antiossidante fosfito 168 \u00e8 la variet\u00e0 di antiossidanti prodotta e consumata a livello nazionale, seconda solo al 1010. I prodotti 626 e 618 sono utilizzati principalmente per la lavorazione ad alta temperatura di materiali polimerici o di prodotti intorno ai 300 \u2103; il ruolo dei materiali polimerici \u00e8 quello di migliorare efficacemente la resistenza all'ossidazione termica ad alta temperatura, mantenendo al contempo un buon aspetto dei prodotti polimerici.<br \/>\n(3) Antiossidanti a base di zolfo<br \/>\nGli antiossidanti a base di zolfo e fosforo sono simili al ruolo principale di rimozione degli idroperossidi, ma anche come antiossidanti ausiliari. La produzione nazionale di antiossidanti contenenti zolfo in base alla struttura molecolare pu\u00f2 essere suddivisa in antiossidanti a base di esteri di zolfo, antiossidanti a base di bisfenolo di zolfo e antiossidanti fenolici a base di etere di zolfo, in 3 variet\u00e0. La molecola dell'antiossidante tiobisfenolo contiene una struttura fenolica inibita; nei materiali polimerici presenta un'elevata resistenza all'ossigeno e al calore; di solito l'antiossidante tiobisfenolo \u00e8 suddiviso nel tipo principale di antiossidante fenolico inibito.<br \/>\n(4) Passivatore di ioni metallici<br \/>\nI passivatori di ioni metallici contengono idrazide, ossima e condensato di aldeide-ammina e altri gruppi di coordinazione, che complessano gli ioni metallici. Il prodotto pi\u00f9 rappresentativo \u00e8 il 1024, che \u00e8 un composto di tipo diidrazidico e contiene anche un gruppo funzionale fenolico combinato ostacolato, che conferisce al prodotto sia la resistenza al rame sia la resistenza all'invecchiamento da calore e ossigeno.<br \/>\n(5) Antiossidanti a base di amine aromatiche<br \/>\nGli antiossidanti amminici aromatici sono generati dalla condensazione dell'aminofenolo o dell'idrochinone con l'anilina; questo tipo di prodotto ha un colore pi\u00f9 scuro, \u00e8 un antiossidante inquinante e la maggior parte dei prodotti ha un certo grado di tossicit\u00e0, un gran numero di prodotti in gomma, altri materiali polimerici, l'uso di meno, e questo tipo di antiossidante \u00e8 anche conosciuto come antiossidante.<\/p>\n<h1><strong><b>Contattateci ora!<\/b><\/strong><\/h1>\n<h4><strong><b>Se avete bisogno di Price, inserite i vostri dati di contatto nel modulo sottostante; di solito vi contatteremo entro 24 ore.
