Acide Sebacic (CAS # 111-20-6)
Gusaba
Ikoreshwa cyane cyane nkibikoresho fatizo bya plasitike ya sebacate na nylon molding resin, kandi irashobora no gukoreshwa nkibikoresho fatizo byamavuta yo kwisiga yihanganira ubushyuhe bwinshi. Ibicuruzwa byingenzi bya ester ni methyl ester, isopropyl Ester, butyl ester, octyl Ester, nonyl ester na benzyl ester, est est ikunze gukoreshwa ni dibutyl sebacate hamwe na acide acide dioctyl.
Decyl Diester plasitike irashobora gukoreshwa cyane muri polyvinyl chloride, resin ya alkyd, polyester resin na polyamide molding resin, kubera uburozi bwayo buke hamwe nubushyuhe bukabije, ikoreshwa kenshi mubintu bimwe bidasanzwe. Ibinyomoro bya nylon biva muri acide ya sebacic bifite ubukana bwinshi hamwe no kwinjiza neza, kandi birashobora no gutunganywa mubicuruzwa byinshi byihariye bigamije. Acide Sebacic nayo ni ibikoresho fatizo byoroshya reberi, surfactants, ibifuniko n'impumuro nziza.

Umutekano
Acide Sebacic mubyukuri ntabwo ari uburozi, ariko cresol ikoreshwa mubikorwa ni uburozi kandi igomba kurindwa uburozi (reba cresol). Ibikoresho byo kubyaza umusaruro bigomba gufungwa. Abakoresha bagomba kwambara masike na gants.
Gupakira & Ububiko
Bipakiye mu mifuka iboshywe cyangwa ikivuguto cyometseho imifuka ya pulasitike, buri mufuka ufite uburemere bwa 25 kg, 40kg, 50kg cyangwa 500kg. Ubike ahantu hakonje kandi uhumeka, umuriro nubushuhe. Ntukavange na aside aside na alkali. Ukurikije ibiteganywa kubika no gutwara.
Intangiriro
Kumenyekanisha Acide ya Sebacic - ibintu byinshi, byera byera bya kirisiti yazamutse cyane mu myaka yashize, bitewe nuburyo butandukanye bukoreshwa mu nganda nyinshi. Acide Sebacic ni aside ya dicarboxylic hamwe na formula ya chimique HOOC (CH2) 8COOH kandi irashobora gushonga mumazi, inzoga, na ether. Iyi aside kama isanzwe iboneka mu mbuto z’uruganda rwa peteroli, kandi ni kimwe mu bikoresho by’ibanze bikoreshwa mu nganda z’imiti.
Acide Sebacic ikoreshwa cyane nkibikoresho fatizo bya plasitike ya sebacate na nylon molding resin. Ibi biterwa nubushobozi bwayo bwo kuzamura cyane ubworoherane nubworoherane bwa polymers zitandukanye bitabangamiye imikorere yabo cyangwa ituze. Yongera imbaraga zo guhangana nubushyuhe bukabije, gukata, no gutobora kimwe no kunoza imbaraga zingana no kwikuramo ibikoresho bya nylon. Kubera iyo mpamvu, imaze kwemerwa cyane mu nganda za plastiki.
Acide Sebacic nayo ikoreshwa cyane mugukora amavuta yo kwisiga yubushyuhe bwo hejuru. Bitewe nuko ihujwe nubushyuhe bwo hejuru cyane, ikora nkibanze ryiza ryamavuta munganda zitwara ibinyabiziga nindege. Imiterere yacyo ihindagurika itanga uburyo bwo kwihanganira ubushyuhe bwinshi hamwe no kugabanya ubukana no kwambara mugihe byizewe kandi bikora.
Ahandi hantu aside acide isanga ikoreshwa ni mugukora ibifatika hamwe nimiti yihariye. Bikunze gukoreshwa mubifata kubera ibyiza byo gutose no kwinjira. Acide Sebacic ikoreshwa mugukora ibintu bifatika cyane kuko ishobora kunoza imiterere yifatizo.
Acide Sebacic nayo ikoreshwa nka inhibitori ya ruswa mugutunganya amazi no kubyara amavuta. Imikorere yayo mukurinda ingese na okiside ituma biba byiza kumiyoboro nibindi bikoresho bikoreshwa mugutwara no gutunganya amavuta na gaze gasanzwe.
Bitewe nimiterere yacyo yera ya kirisiti, aside sebacic irashobora kumenyekana biturutse kumiti yindi miti. Ibi bituma ushiramo inganda zikora imiti nkibisanzwe. Irashobora gukoreshwa nkururimi, guhuza no gusiga amavuta mugukora dosiye zitandukanye nka tableti, capsules, na suppository.
Mu gusoza, aside acide ya sebacic ihindagurika hamwe nuburyo bwinshi bwo kuyikoresha bituma iba igicuruzwa cyiza cyane cyo gukoreshwa mu nganda nyinshi kuva mu binyabiziga no mu kirere kugeza mu bya farumasi n’imiti. Ihungabana ryayo mubihe bikabije bituma iba ingenzi mu nganda nyinshi zirimo plastiki, peteroli, gaze, no gutunganya amazi, mu gihe ubushobozi bwayo bwo kuzamura imikorere ya polymers bwerekana agaciro kayo. Muri rusange, acide sebacic nikintu gikomeye cyubaka kubicuruzwa byinshi byabaye ngombwa mubuzima bwa none.
