Sebacic acid haina muchetura, asi cresol inoshandiswa mukugadzira ine muchetura uye inofanirwa kuchengetedzwa kubva kune chepfu (ona cresol).Midziyo yekugadzira inofanira kuvharwa.Vashandi vanofanira kupfeka masiki uye magurovhosi.
Kurongedza & Kuchengeta
Yakaiswa mumabhegi akarukwa kana ehemp akaiswa mapurasitiki, bhegi rega rega rine huremu hwe25kg, 40kg, 50kg kana 500kg.Chengeta munzvimbo inotonhorera uye ine mhepo, moto uye mwando.Usasanganise nemvura acid uye alkali.Zvinoenderana nezvinodiwa zvekuchengetedza uye kutakura zvinopisa.
Nhanganyaya
Kuunza Sebacic Acid - iyo inochinja-chinja, chena patchy crystal iyo yakakwira mukuzivikanwa nekufamba kwemakore, nekuda kwemhando dzakasiyana dzekushandisa mumaindasitiri mazhinji.Sebacic acid idicarboxylic acid ine kemikari formula HOOC(CH2)8COOH uye inonyungudika mumvura, doro, uye ether.Iyi organic acid inowanzo wanikwa kubva kumbeu dzemafuta ecastor chirimwa, uye ndiyo imwe yeakanyanya kukosha zvigadzirwa zvinoshandiswa muindasitiri yemakemikari.
Sebacic acid inonyanya kushandiswa seyakagadzirwa sebacate plasticizer uye nylon molding resin.Izvi zvinokonzerwa nekugona kwayo kuwedzera zvakanyanya elasticity uye kuchinjika kwemapolymer akasiyana pasina kukanganisa kuita kwavo kana kugadzikana.Iyo inosimudzira kuramba kutonhora kwakanyanya, kucheka, uye punctures pamwe nekunatsiridza kusimba uye kudzvinyirira simba renylon zvinhu.Nekuda kweizvozvo, yakawana kugamuchirwa kwakakura muindasitiri yepurasitiki.
Sebacic acid inoshandiswawo zvakanyanya mukugadzirwa kwemafuta ekuzora anodzivirira kutonhora kwakanyanya.Nekuda kwekuenderana kwayo nepamusoro-tembiricha nharaunda, inoshanda seyakanakisa base yemafuta ekuzora mumaindasitiri emotokari uye aerospace.Hunhu hwayo hwekudziya hwakadzikama hunobvumira kushivirira kwakanyanya kune yakanyanya kupisa maapplication ane kuderedzwa kukweshera uye kupfeka uku uchivimbisa kuvimbika uye kuita.
Imwe nzvimbo iyo sebacic acid inowana kushandiswa kwayo mukugadzira zvinonamira uye makemikari akasarudzika.Inowanzo shandiswa mukunamira nekuda kwekunyorova kwayo uye kupinda mukati.Sebacic acid inoshandiswa kugadzira adhesives epamusoro-soro nokuti inogona kuvandudza zvinhu zvekunamatira zvekunamatira.
Sebacic acid inoshandiswawo se corrosion inhibitor mukurapa kwemvura uye kugadzirwa kwemafuta.Kushanda kwayo mukudzivirira ngura uye oxidation inoita kuti ive yakanaka kune mapaipi uye zvimwe zvinoshandiswa pakutakura uye kugadzira mafuta uye gasi rechisikigo.
Nekuda kweiyo chena patchy crystal hunhu, sebacic acid inogona kuzivikanwa nyore kubva kune mamwe makemikari.Izvi zvinoita kuti ive inoyevedza kubatanidzwa kweindasitiri yemishonga semubatsiri.Inogona kushandiswa seyakanyungudutswa, binder uye lubricant mukugadzira emhando dzakasiyana dzeyero senge mahwendefa, capsules, uye suppositories.
Mukupedzisa, kuita kwakasiyana-siyana kwesebacic acid uye kuwanda kwekushandisa kunoita kuti ive chigadzirwa chinoyevedza chekushandisa mumaindasitiri mazhinji kubva kumotokari uye aerospace kusvika pakugadzira mishonga nemakemikari.Kugadzikana kwayo pasi pemamiriro akanyanya kuita kuti ive yakakosha mumaindasitiri akati wandei anosanganisira epurasitiki, oiri, gasi, uye kurapwa kwemvura, nepo kugona kwayo kwekusimudzira mashandiro emapolymers kunoratidza kukosha kwayo.Pakazere, sebacic asidhi yakakosha kuvaka kune akati wandei zvigadzirwa zvave zvakakosha kuhupenyu hwazvino.
