Uso della TBC"},"content":{"rendered":"<h2 class=\"wp-block-heading\">Che cos'\u00e8 la TBC?<\/h2>\n\n<!-- lc-qa-start -->\n<p><strong>Quick answer:<\/strong> A practical coating formulation choice starts with the application environment, then checks film formation, adhesion, appearance, and process stability under real production conditions.<\/p>\n<!-- lc-qa-end -->\n\n\n\n\r\n\r\n\r\n<p>La formula molecolare del TBC, C18H32O7, massa molare 360-44 g\/mol, \u00e8 un liquido incolore o giallo chiaro, miscelabile con acetone, CCl4, olio minerale, acido acetico, olio di ricino, alcool e i loro solventi; insolubile in acqua, non tossico e insapore, bassa volatilit\u00e0, resistenza al calore, alla luce e all'acqua. Il TBC ha una buona compatibilit\u00e0 con la resina vinilica, l'acetilbutirrato di cellulosa, l'acetato di cellulosa, la benzilcellulosa, l'etilcellulosa, ecc. ed \u00e8 un buon plastificante con una migliore efficienza di plastificazione. Plastificante; il TBC ha anche le caratteristiche di antibatterico senza crescita di batteri, non irritante, ignifugo e degradabile.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Metodo di preparazione della TBC<\/h2>\r\n\r\n\r\n\r\n<p>L'acido citrico e l'n-butanolo reagiscono in presenza di un catalizzatore e di un agente che trasporta l'acqua per generare il tributilcitrato; il prodotto viene ottenuto attraverso processi quali dealcolizzazione, neutralizzazione, lavaggio con acqua, stripping a vapore, decolorazione e filtropressa.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Principio della reazione TBC<\/h2>\r\n\r\n\r\n\r\n<p>Il citrato di tributile pu\u00f2 essere sintetizzato dalla reazione di esterificazione di acido citrico e n-butanolo. I catalizzatori tradizionali per l'esterificazione sono acidi forti come l'acido solforico e l'acido benzenesolfonico, che hanno un prezzo basso e un'elevata attivit\u00e0 catalitica, ma presentano molte reazioni collaterali, complicati processi di post-trattamento, grave corrosione delle apparecchiature ed emissioni di acidi di scarto che inquinano gravemente l'ambiente. Pertanto, la sintesi non catalizzata da acidi di prodotti esteri \u00e8 stata un obiettivo di ricerca a lungo termine. Esistono molti studi sull'acido eteropolico supportato da carbone attivo, sulla resina a scambio cationico e sul cloruro misto di terre rare. Tuttavia, i metodi di cui sopra hanno molte fasi di processo post-trattamento, che non sono facili da controllare, e il processo di preparazione del catalizzatore \u00e8 complicato, il che non favorisce l'applicazione e la promozione.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\">Uso TBC<\/h2>\r\n\r\n\r\n\r\n<p>Questo prodotto \u00e8 solubile nella maggior parte dei solventi organici. Ha le caratteristiche di bassa volatilit\u00e0, buona compatibilit\u00e0 con la resina ed elevata efficienza di plastificazione. Pertanto, pu\u00f2 essere utilizzato nella produzione di imballaggi alimentari e di prodotti medici e sanitari in vari paesi del mondo, oltre che di peluche per bambini, prodotti farmaceutici, prodotti medici, aromi e profumi. Produzione di cosmetici e altri settori.<\/p>\r\n\r\n\r\n\r\n<p>Il TBC pu\u00f2 conferire ai prodotti una buona resistenza al freddo, all'acqua e alla muffa. La resina, dopo essere stata plastificata con questo prodotto, presenta una buona trasparenza e prestazioni di flessione a bassa temperatura, ha una bassa volatilit\u00e0 e una bassa estraibilit\u00e0 in diversi mezzi, una buona stabilit\u00e0 termica e non cambia colore se esposta al calore. L'olio lubrificante prodotto con TBC ha buone propriet\u00e0 lubrificanti.<\/p>\r\n\r\n\r\n\r\n<p>Negli ultimi anni, i principali plastificanti spesso utilizzati nell'industria sono i plastificanti ftalati. Poich\u00e9 i plastificanti ftalati possono indurre la cancerogenesi, i Paesi stranieri ne hanno controllato rigorosamente l'uso e anche il mio Paese ha formulato leggi e regolamenti pertinenti che ne elimineranno gradualmente l'uso nei materiali di imballaggio degli alimenti, nelle apparecchiature mediche e nei giocattoli. Il citrato di tributile (TBC) \u00e8 un nuovo tipo di plastificante plastico non tossico. Ha attirato un'ampia attenzione per la sua buona compatibilit\u00e0, l'elevata efficienza di plastificazione, la non tossicit\u00e0, la non volatilit\u00e0 e la forte resistenza agli agenti atmosferici. \u00c8 diventato la prima scelta per sostituire l'o-benzene. Prodotti ecologici per la protezione ambientale del diformato.<\/p>\r\n\r\n\r\n\r\n<p>Con l'aumento della consapevolezza della popolazione nei confronti della tutela ambientale e il miglioramento delle leggi e dei regolamenti in materia, lo sviluppo e la produzione di tributilcitrato hanno ottime prospettive di sviluppo.<\/p>\r\n\r\n\r\n\r\n<h2 class=\"wp-block-heading\"><strong>Plastificanti ritardanti di fiamma della stessa serie<\/strong><\/h2>\r\n<table style=\"border-collapse: collapse;
