Kenmerken van verschillende veel voorkomende rubbercompoundprocessen

Het mengen van rubber is het gelijkmatig dispergeren van verschillende verbindingen in rubber met behulp van de mechanische kracht van de rubbervervaardigingsmachine, om zo een meerfasig colloïdaal dispersiesysteem te vormen met rubber als medium of een mengsel van rubber en enkele compatibele componenten (matchingagent, andere polymeren) als medium, en incompatibele matchingagentia (zoals poedervulstoffen, zinkoxide, pigmenten, enz.) als gedispergeerde fase. proces. De specifieke technische vereisten van het mengproces zijn: uniforme verspreiding van het mengmiddel, zodat de beste dispersie van het mengmiddel, vooral het versterkende mengmiddel zoals roet, wordt bereikt om consistente prestaties van het rubber te garanderen. Het resulterende rubber wordt 'compounding rubber' genoemd en de kwaliteit ervan heeft een belangrijke invloed op de verdere verwerking en productkwaliteit.

Hoe de temperatuurbestendigheid van rubber te verbeteren

Oplossingen

14-04-2023

Weerstand tegen veroudering door hete lucht of hitteveroudering wordt steeds belangrijker, vooral in automobieltoepassingen waar rubberen onderdelen meestal worden gebruikt in overdekte ruimtes met hoge omgevingstemperaturen. Autofabrikanten voelen een toenemende druk om zich in te zetten voor een langere levensduur van hun rubberen onderdelen. De eigenschappen van anaërobe veroudering door hitte en de eigenschappen van veroudering door hitte en lucht zijn verschillend. Het rubber heeft een betere hittebestendigheid, maar is mogelijk nog steeds niet bestand tegen zuurstofaanvallen.

Hoe u de kosten van het compounderen van rubber kunt verlagen

Oplossingen

14-04-2023

In de zeer competitieve wereld van de rubberindustrie zijn de kosten van compounding van cruciaal belang voor het economische succes van een product. Het is mogelijk een samenstellingsformulering te ontwikkelen die qua prestatie aan de behoeften van de klant voldoet, maar die door de klant wordt afgewezen omdat deze te duur is. Bovendien worden rubberproducten over het algemeen verkocht per volume in plaats van per gewicht (gevormde producten hebben over het algemeen afmetingen). Daarom is het zinvol om de 'kosten per volume' te vergelijken in plaats van de 'kosten per gewicht' van het rubber.
