Intshayelelo
Ukwazisa i-Sebacic Acid-ikristale eguquguqukayo, emhlophe ebhayibhile eye yanda ngokuthandwa kwiminyaka edlulileyo, enkosi kuluhlu lwayo lwezicelo kumashishini amaninzi. I-asidi ye-Sebacic yi-asidi ye-dicarboxylic kunye ne-chemical formula ye-HOOC (CH2) 8COOH kwaye iyanyibilika emanzini, e-alcohol, kunye ne-ether. Le asidi yendalo iqhele ukufunyanwa kwimbewu yesityalo se-oyile ye-castor, kwaye yenye yezona zinto zibalulekileyo ezisetyenziswa kwishishini lemichiza.
I-asidi ye-Sebacic isetyenziswa kakhulu njengemathiriyeli ekrwada ye-sebacate plasticizer kunye ne-nylon yokubumba intlaka. Oku kungenxa yokukwazi ukomeleza kakhulu ukuqina kunye nokuguquguquka kweepholima ezahlukeneyo ngaphandle kokubeka esichengeni ukusebenza kwazo okanye ukuzinza. Yongeza ukuxhathisa kumaqondo obushushu agqithisileyo, ukusikwa, kunye nokugqabhuka kunye nokuphucula amandla okuqina kunye noxinzelelo lwemathiriyeli yenayiloni. Ngenxa yoko, iye yamkelwa ngokubanzi kushishino lweplastiki.
I-asidi yeSebacic ikwasetyenziswa kakhulu ekuveliseni ioyile zokuthambisa ezinobushushu obuphezulu.

Ubume bayo obuzinzile nge-thermal ivumela ukunyamezela okukhulu kwizicelo zokushisa okuphezulu kunye nokunciphisa ukukhuhla kunye nokunxiba ngelixa uqinisekisa ukuthembeka kunye nokusebenza.
Enye indawo apho i-sebacic acid ifumana ukusetyenziswa kwayo kukwenza izinto zokuncamathelisa kunye neekhemikhali ezikhethekileyo. Idla ngokusetyenziswa kwizinto zokuncamathelisa ngenxa yokumanzisa kwayo kakuhle kunye nokungena kwayo. I-asidi ye-Sebacic isetyenziselwa ukuvelisa i-adhesives ephezulu yokusebenza kuba inokuphucula iimpawu zokubambelela kwi-adhesive.
I-asidi ye-Sebacic iphinda isetyenziswe njenge-corrosion inhibitor kunyango lwamanzi kunye nokuveliswa kweoli. Ukusebenza kwayo ekuthinteleni umhlwa kunye ne-oxidation yenza ukuba ilungele imibhobho kunye nezinye izixhobo ezisetyenziselwa ukuthutha kunye nokucubungula ioli kunye negesi yendalo.
Ngenxa yeempawu zayo ezimhlophe zekristale, i-sebacic acid inokuchongwa ngokulula kwezinye iikhemikhali. Oku kuyenza ibe yinxalenye enomtsalane kwishishini loxubo-mayeza njengoncedo. Ingasetyenziswa njenge-diluent, binder kunye ne-lubricant xa kusenziwa iifom zedosi ezahlukeneyo ezifana neetafile, iicapsules, kunye neesuppositories.
Ukuqukumbela, ukuguquguquka kwe-sebacic acid kunye noluhlu olubanzi losetyenziso kuyenza ibe yimveliso enomtsalane kakhulu ukuba isetyenziswe kuwo wonke amashishini amaninzi ukusuka kwiimoto kunye ne-aerospace ukuya kwimveliso yamayeza kunye neekhemikhali. Ukuzinza kwayo phantsi kweemeko ezinzima kuyenza ibaluleke kakhulu kumashishini amaninzi kuquka iplastiki, ioyile, igesi, kunye nonyango lwamanzi, ngelixa ukukwazi kwayo ukuphucula ukusebenza kweepolymers kubonisa ixabiso layo. Ngokubanzi, i-sebacic acid sisixhobo esibalulekileyo sokwakha inani leemveliso eziye zayimfuneko kubomi banamhlanje.
