Dimethyldineodecanoatetin Gebruik<\/strong><\/h2>\n

1. Dimethyldineodecanoatetine wordt gebruikt als een effici\u00ebnte katalysator bij de productie van polyurethaanschuim, coatings, kleefstoffen en afdichtingsmiddelen.<\/p>\n

2. Dimethyldineodecanoatetine wordt gebruikt in tweecomponentenpolyurethaan, polyester, nitroverven, inkten, uithardingskatalysatoren, enz. Het heeft een goede oxidatieweerstand.
\n3. Dimethyldineodecanoatetine wordt gebruikt bij de productie van polyurethaan kunststoffen, polyurethaan coatings, siliconenrubber katalysatoren, katalysatoren enzovoort.<\/p>\n

Het heeft de hoogste katalytische activiteit van de reeks organotinekatalysatoren, waardoor zeer korte gel- en antikleeftijden worden verkregen. De activiteit is vergelijkbaar met die van dibutyltindiacetaat (DBTDA), maar zonder de azijnzuurgeur of bijtende werking van DBTDA. Het vervangt DBTDL in veel polyurethaanschuimsystemen met de voordelen van een lage dosering en lage kosten. Het heeft een lager vriespunt dan DBTDL en een iets betere hydrolyseweerstand. Het kan worden gebruikt voor snel uithardende giet- en spuitelastomeren, kan worden gebruikt in polyurethaan- en siliconensystemen die uitharden bij kamertemperatuur en is bijzonder geschikt voor alifatische polyurethaansystemen.<\/p>\n

Polyurethaan katalysator selectie analyse<\/p>\n

Er zijn twee hoofddoelen voor het gebruik van katalysatoren:<\/p>\n

1, Om de reactie te laten verlopen in de richting die we verwachten;
\n2, om de reactiesnelheid te regelen, de reactietijd te verkorten en de productie-effici\u00ebntie te verbeteren.<\/p>\n

Bij de selectie van polyurethaanschuimkatalysatoren worden polyurethaanschuimproducten voornamelijk gesynthetiseerd uit polyether, isocyanaat, schuimmiddel, katalysator enzovoort. Het belangrijkste proces van schuimvorming wordt over het algemeen als volgt beschouwd:
\n1, door middel van fysische methoden en chemische methoden in het polyurethaan reactiesysteem om schuim te produceren, en laat het schuim uniform verspreid in het reactiesysteem, waarin de belangrijkste schuimmethode is het gebruik van water en isocyanaat productie van kooldioxide te schuimen.
\n2. Het proces van schuimvorming vereist dat de viscositeit van het reactiesysteem toeneemt om het ontsnappen van het schuim te stabiliseren.
\n3\u3001Wanneer de schuimvorming het gewenste aantal en de gewenste grootte bereikt, moet de viscositeit van het reactiesysteem blijven toenemen en zelfs een crosslinking systeem vormen om het schuim te stabiliseren en te vormen tot een product.<\/p>\n

In dit geval hebben we ten minste twee katalysatoren nodig om de reactie te reguleren, \u00e9\u00e9n katalysator is om de reactie van isocyanaat en water te bevorderen, dat wil zeggen, om de schuimreactie te bevorderen, kies meestal aminekatalysatoren; de andere katalysator is om de reactie van isocyanaat en polyether of alcohol te bevorderen, dat wil zeggen, de reactie van polyurethaan molecuulketengroei en verknoping, kies meestal metaalkatalysatoren. Daarom kiezen we in het proces van polyurethaanschuimsynthese meestal aminekatalysatoren en organometaalkatalysatoren om samen te werken om synergetische effecten te produceren om de beste resultaten te bereiken.<\/p>\n

Organometaalkatalysatoren<\/p>\n

In polyurethaanelastomeren en kleefstoffen, coatings, afdichtmiddelen, waterdichte coatings, bestratingsmaterialen en andere formuleringen worden meestal de traditionele organotin en andere organometaalkatalysatoren gebruikt, die zeer effectief zijn in het bevorderen van de reflectie van isocyanaatgroep en hydroxylgroep, maar met de eisen van milieubescherming worden milieuvriendelijke organobismut- en zinkproducten steeds vaker gebruikt.<\/p>","protected":false},"excerpt":{"rendered":"
