Sebacic acid ha e le hantle ha e na chefo, empa cresol e sebelisoang tlhahisong e chefo 'me e lokela ho sireletsoa ho chefo (bona cresol).Lisebelisoa tsa tlhahiso li lokela ho koaloa.Basebetsi ba lokela ho roala limaske le liatlana.
Ho paka & Polokelo
E phuthetsoe ka mekotleng e lohiloeng kapa ea hemp e kentsoeng ka mekotla ea polasetiki, mokotla o mong le o mong o na le boima ba 25kg, 40kg, 50kg kapa 500kg.Boloka sebakeng se phodileng le se nang le moya, mollo le mongobo.U se ke ua kopanya le asiti ea metsi le alkali.Ho ea ka litokisetso tsa polokelo le lipalangoang tse tukang.
Selelekela
E hlahisa Sebacic Acid - kristale e feto-fetohang, e tšoeu e patchy e ntseng e tuma haholo ho theosa le lilemo, ka lebaka la mefuta e fapaneng ea ts'ebeliso ea eona ho indasteri e mengata.Sebacic acid ke dicarboxylic acid e nang le foromo ea lik'hemik'hale HOOC(CH2)8COOH' me e qhibiliha metsing, joala le ether.Asiti ena ea tlhaho hangata e fumanoa peōng ea semela sa oli ea castor, 'me ke e' ngoe ea lisebelisoa tsa bohlokoahali tse sebelisoang indastering ea lik'hemik'hale.
Sebacic acid e sebelisoa haholo-holo e le thepa e tala bakeng sa polasetiki ea sebacate le resin ea ho bopa nylon.Sena se bakoa ke bokhoni ba eona ba ho ntlafatsa haholo elasticity le ho feto-fetoha ha li-polymer tse fapaneng ntle le ho senya ts'ebetso ea tsona kapa botsitso.E matlafatsa ho hanyetsa mocheso o feteletseng, ho khaola, le ho phunyeha hammoho le ho ntlafatsa matla a ho tiea le a khatello ea thepa ea nylon.Ka lebaka leo, e fumane kamohelo e pharaletseng indastering ea polasetiki.
Sebacic acid e boetse e sebelisoa haholo tlhahisong ea oli e hanyetsanang le mocheso o phahameng.Ka lebaka la ho tsamaellana le maemo a mocheso o phahameng, e sebetsa e le setsi se setle sa mafura indastering ea likoloi le ea lifofane.Sebopeho sa eona se tsitsitseng ka mocheso se lumella ho mamellana ho hoholo ha mocheso o phahameng ka ho fokotsa likhohlano le ho roala ha ho ntse ho netefatsa ho tšepahala le ho sebetsa.
Sebaka se seng seo asiti ea sebacic e sebelisoang ho eona ke ha ho etsoa likhomaretsi le lik'hemik'hale tse khethehileng.E sebelisoa hangata ho li-adhesives ka lebaka la botle ba eona ba ho kolobisa le ho phunyeletsa.Sebacic acid e sebelisoa ho hlahisa li-adhesives tse sebetsang hantle hobane e ka ntlafatsa thepa ea ho khomarela ea sekhomaretsi.
Sebacic acid e boetse e sebelisoa e le corrosion inhibitor kalafo ea metsi le tlhahiso ea oli.Ho sebetsa ha eona ho thibela mafome le oxidation ho etsa hore e be e loketseng liphaephe le lisebelisoa tse ling tse sebelisetsoang ho tsamaisa le ho lokisa oli le khase ea tlhaho.
Ka lebaka la sebopeho sa eona se tšoeu sa kristale, sebacic acid e ka tsejoa habonolo ho tsoa lik'hemik'hale tse ling.Sena se etsa hore e be karolo e khahlang bakeng sa indasteri ea meriana joalo ka mothusi.E ka sebelisoa e le sehlaseli, se tlamang le setlolo ha ho etsoa mefuta e fapaneng ea litekanyetso tse kang matlapa, li-capsules le li-suppositories.
Qetellong, ho tenyetseha ha sebacic acid le mefuta e mengata ea ts'ebeliso e etsa hore e be sehlahisoa se khahlehang haholo bakeng sa tšebeliso ea liindasteri tse ngata ho tloha ho tsa likoloi le tsa sefofane ho ea ho tlhahiso ea meriana le ea lik'hemik'hale.Ho tsitsa ha eona tlas'a maemo a feteletseng ho etsa hore e be ea bohlokoa haholo liindastering tse 'maloa ho kenyeletsa polasetiki, oli, khase le phekolo ea metsi, ha bokhoni ba eona ba ho ntlafatsa ts'ebetso ea li-polymers bo bontša bohlokoa ba eona.Ka kakaretso, sebacic acid ke moaho oa bohlokoa bakeng sa lihlahisoa tse ngata tse seng li le bohlokoa bophelong ba sejoale-joale.
