Umhlinzeki we-Sebacic Acid — I-Plasticizer kanye ne-Nylon Grade

Kuyini i-Sebacic Acid?

I-Sebacic Acid (i-decanedioic acid, i-C₁₀H₁₈O₄) iyi-dicarboxylic acid ene-C10 carbon chain, ekhiqizwa ngokuhweba kusuka ku-castor oil ngokuhlanganiswa kwe-alkali ye-ricinoleic acid. Ubude bayo be-chain obude uma buqhathaniswa ne-adipic acid bunikeza ukuguquguquka okuhle kakhulu emazingeni okushisa aphansi, okwenza i-sebacic acid ibe yi-dicarboxylate ekhethwayo yokukhiqizwa kwe-plasticizer yesimo sezulu esibandayo kanye ne-lubricant ester. Iphinde isetshenziswe njenge-monomer etholakala ku-bio ekwakhiweni kwe-polyamide kanye ne-polyester.

I-Dioctyl Sebacate (DOS) Plasticizer

Ukusetshenziswa okuyinhloko kwe-sebacic acid ezimbonini kusekukhiqizweni kwe-dioctyl sebacate (DOS, noma i-bis(2-ethylhexyl) sebacate), i-plasticizer eguquguqukayo ebandayo ye-PVC. I-DOS inikeza ukuguquguquka okuhle kakhulu kokushisa okuphansi (kuze kufike ku-−60 °C) futhi iyathandwa ekufakweni kwentambo kanye nekhebula ezindaweni ezibandayo, ukuhlobisa kwangaphakathi kwezimoto, kanye nokupakisha okuguquguqukayo okumele kuhlale kuthambile emazingeni okushisa aphansi. Ukuvunyelwa kwayo kokuxhumana kokudla (FDA, EU) kwandisa ukusetshenziswa kwayo ezicelweni zokupakisha eziguquguqukayo.

Ama-polyamides e-Nylon-6,10 kanye ne-Bio-Based

I-Sebacic acid isabela ne-hexamethylenediamine (HMDA) ukuze yakhe i-nylon-6,10, i-polyamide esekelwe kwi-semi-bio enokumuncwa komswakama okuphansi kune-nylon-6,6 kanye nokumelana okuhle kwamakhemikhali. Futhi iyi-monomer kwi-nylon-6,10 esekelwe kwi-bio ekhiqizwa kusuka ku-castor oil, esetshenziswa kumapulasitiki obunjiniyela, ama-monofilaments, kanye nemicu yebhulashi. I-Sebacic acid isetshenziswa futhi njenge-comonomer kuma-polyester akhethekile kanye nama-polyurethanes adinga ukuguquguquka okuthuthukisiwe kanye nokuzinza kwe-hydrolytic.

Ama-Esters Okugcoba kanye Nokunye Ukusetshenziswa

Ama-ester e-Sebacate ngale kwe-DOS — kufaka phakathi i-diisodecyl sebacate kanye namanye ama-ester e-alcohol e-C8-C13 — asetshenziswa njengezinto zokwenziwa zokugcoba, ikakhulukazi kumafutha e-turbine endiza kanye noketshezi lwe-hydraulic olushisa kakhulu. I-Sebacic acid isetshenziswa futhi ekwakhiweni kwe-corrosion inhibitor kanye nanjenge-cross-linker kwezinye izinhlelo zokunamathela.
