Sebacic Acid (CAS # 111-20-6)
Kugwiritsa ntchito
Amagwiritsidwa ntchito ngati zopangira sebacate plasticizer ndi nayiloni akamaumba utomoni, ndipo angagwiritsidwe ntchito ngati zopangira kwa kutentha kugonjetsedwa mafuta mafuta. Ma ester ake akuluakulu ndi methyl ester, isopropyl Ester, butyl ester, octyl Ester, nonyl ester ndi benzyl ester, esters omwe amagwiritsidwa ntchito kwambiri ndi dibutyl sebacate ndi sebacic acid dioctyl mbewu.
Decyl Diester plasticizer itha kugwiritsidwa ntchito kwambiri mu polyvinyl kolorayidi, utomoni wa alkyd, utomoni wa poliyesitala ndi utomoni wowuma wa polyamide, chifukwa cha kawopsedwe kakang'ono komanso kukana kutentha kwambiri, nthawi zambiri amagwiritsidwa ntchito pazamankhwala apadera. Utoto woumba nayiloni wopangidwa kuchokera ku sebacic acid umakhala wolimba kwambiri komanso umayamwa pang'ono chinyezi, komanso umatha kusinthidwa kukhala zinthu zambiri zapadera. Sebacic acid ndi zopangira zofewetsa mphira, ma surfactants, zokutira ndi zonunkhira.

kusungunuka pang'ono kusungunuka m'madzi, kusungunuka mu mowa ndi ether.
Chitetezo
Sebacic acid kwenikweni alibe poizoni, koma cresol yomwe imagwiritsidwa ntchito popanga ndi poizoni ndipo iyenera kutetezedwa ku chiphe (onani cresol). Zida zopangira ziyenera kutsekedwa. Ogwira ntchito ayenera kuvala masks ndi magolovesi.
Kuyika & Kusunga
Olongedza m'matumba olokedwa kapena hemp okhala ndi matumba apulasitiki, thumba lililonse limalemera 25kg, 40kg, 50kg kapena 500kg. Kusunga pamalo ozizira ndi mpweya wokwanira, moto ndi chinyezi. Osasakaniza ndi madzi acid ndi alkali. Malinga ndi makonzedwe a yoyaka yosungirako ndi mayendedwe.
Mawu Oyamba
Kuyambitsa Sebacic Acid - kristalo yosunthika, yoyera yoyera yomwe yakula kwambiri m'zaka zapitazi, chifukwa cha ntchito zake zosiyanasiyana m'mafakitale ambiri. Sebacic acid ndi dicarboxylic acid yokhala ndi formula ya mankhwala HOOC(CH2)8COOH ndipo imasungunuka m'madzi, mowa, ndi ether. organic acid imeneyi imapezeka kuchokera ku mbewu zamafuta a castor, ndipo ndi imodzi mwazinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito pamakampani opanga mankhwala.
Sebacic asidi zimagwiritsa ntchito ngati zopangira kwa sebacate plasticizer ndi nayiloni akamaumba utomoni. Izi ndichifukwa chakutha kwake kukulitsa kukhazikika komanso kusinthasintha kwa ma polima osiyanasiyana popanda kusokoneza magwiridwe antchito kapena kukhazikika kwawo. Imawonjezera kukana kutentha kwambiri, mabala, ndi ma punctures komanso imathandizira kulimba komanso kulimba kwa zida za nayiloni. Zotsatira zake, zakhala zikuvomerezedwa kwambiri m'makampani apulasitiki.
Sebacic acid imagwiritsidwanso ntchito kwambiri popanga mafuta opaka mafuta osamva kutentha kwambiri. Chifukwa chogwirizana ndi malo otentha kwambiri, imakhala ngati maziko abwino kwambiri opangira mafuta m'mafakitale amagalimoto ndi ndege. Chikhalidwe chake chokhazikika cha thermally chimalola kulolerana kwambiri ndi ntchito zotentha kwambiri zokhala ndi mikangano yochepetsedwa ndi kuvala ndikuwonetsetsa kudalirika ndi ntchito.
Mbali ina yomwe sebacic acid imagwiritsiridwa ntchito ndi kupanga zomatira ndi mankhwala apadera. Amagwiritsidwa ntchito kwambiri pomatira chifukwa cha kunyowetsa kwake komanso kulowerera kwake. Sebacic acid imagwiritsidwa ntchito popanga zomatira zapamwamba kwambiri chifukwa zimatha kukonza zomatira zomatira.
Sebacic acid imagwiritsidwanso ntchito ngati corrosion inhibitor pochiza madzi ndi kupanga mafuta. Kuchita bwino kwake popewa dzimbiri ndi okosijeni kumapangitsa kuti ikhale yabwino kwa mapaipi ndi zida zina zomwe zimagwiritsidwa ntchito ponyamula ndi kukonza mafuta ndi gasi.
Chifukwa cha mawonekedwe ake oyera a kristalo, sebacic acid imatha kudziwika mosavuta kuchokera kumankhwala ena. Izi zimapangitsa kuti zikhale zokopa chidwi chamakampani opanga mankhwala ngati chothandizira. Itha kugwiritsidwa ntchito ngati chosungunulira, chomangira komanso chopaka mafuta popanga mitundu yosiyanasiyana ya mlingo monga mapiritsi, makapisozi, ndi ma suppositories.
Pomaliza, kusinthasintha kwa sebacic acid ndikugwiritsa ntchito mosiyanasiyana kumapangitsa kuti ikhale chinthu chokongola kwambiri kuti chigwiritsidwe ntchito m'mafakitale ambiri kuyambira pamagalimoto ndi ndege mpaka kupanga mankhwala ndi mankhwala. Kukhazikika kwake pansi pazovuta kwambiri kumapangitsa kuti ikhale yofunikira kwambiri m'mafakitale angapo kuphatikiza pulasitiki, mafuta, gasi, ndi mankhwala amadzi, pomwe kuthekera kwake kopititsa patsogolo magwiridwe antchito a ma polima kukuwonetsa mtengo wake. Ponseponse, sebacic acid ndiyofunikira kwambiri pakupanga zinthu zingapo zomwe zakhala zofunikira pamoyo wamakono.
