I-Sebacic Acid (CAS# 111-20-6)
Isicelo
Isetshenziswa kakhulu njengempahla eluhlaza ye-sebacate plasticizer kanye ne-nylon molding resin, futhi ingasetshenziswa njengempahla eluhlaza kuwoyela wokugcoba ongamelana nokushisa okuphezulu. Imikhiqizo yayo eyinhloko ye-ester i-methyl ester, i-isopropyl Ester, i-butyl ester, i-octyl Ester, i-nonyl ester ne-benzyl ester, ama-ester asetshenziswa kakhulu yizinhlamvu ze-dibutyl sebacate ne-sebacic acid dioctyl.
I-Decyl Diester plasticizer ingasetshenziswa kabanzi ku-polyvinyl chloride, i-alkyd resin, i-polyester resin kanye ne-polyamide yokubumba i-polyamide, ngenxa yobuthi bayo obuphansi kanye nokumelana nokushisa okuphezulu, ivame ukusetshenziswa kwezinye izinjongo ezikhethekile ze-resin. I-resin yokubumba inayiloni ekhiqizwa nge-sebacic acid inokuqina okuphezulu nokumunca umswakama ophansi, futhi ingacutshungulwa ibe yimikhiqizo eminingi ekhethekile. I-Sebacic acid iphinde ibe yimpahla eluhlaza yezithambisa zenjoloba, ama-surfactants, okokumboza namaphunga.

Ukuphepha
I-Sebacic acid empeleni ayinabo ubuthi, kodwa i-cresol esetshenziswa ekukhiqizeni inobuthi futhi kufanele ivikelwe ebuthi (bona i-cresol). Imishini yokukhiqiza kufanele ivalwe. Abasebenzi kufanele bagqoke imaski namagilavu.
Ukupakisha Nokugcina
Ipakishwe ezikhwameni ezilukiwe noma ze-hemp ezifakwe izikhwama zepulasitiki, isikhwama ngasinye sinesisindo esingama-25kg, 40kg, 50kg noma 500kg. Gcina endaweni epholile nengena umoya, umlilo kanye nomswakama. Ungaxubani ne-acid ewuketshezi kanye ne-alkali. Ngokwezinhlinzeko zokugcina ezivuthayo nezokuthutha.
Isingeniso
Sethula i-Sebacic Acid - ikristalu eguquguqukayo, emhlophe ebabazekayo eye yanda ngokuduma phakathi neminyaka edlule, ngenxa yobubanzi bayo bezinhlelo zokusebenza kuzo zonke izimboni eziningi. I-Sebacic acid iyi-dicarboxylic acid enefomula yamakhemikhali engu-HOOC(CH2)8COOH futhi iyancibilika emanzini, etshwaleni, naku-ether. Le acid ephilayo ivame ukutholakala embewini kawoyela we-castor, futhi ingenye yezinto ezibalulekile ezisetshenziswa embonini yamakhemikhali.
I-Sebacic acid isetshenziswa kakhulu njengempahla eluhlaza ye-sebacate plasticizer kanye ne-nylon molding resin. Lokhu kungenxa yekhono layo lokuthuthukisa kakhulu ukunwebeka nokuguquguquka kwama-polymer ahlukahlukene ngaphandle kokuphazamisa ukusebenza noma ukuzinza kwawo. Ithuthukisa ukumelana namazinga okushisa adlulele, ukusikeka, nokubhoboza kanye nokuthuthukisa amandla aqinile nacindezelayo wezinto zenayiloni. Ngenxa yalokho, iye yamukelwa kabanzi embonini yepulasitiki.
I-Sebacic acid iphinde isetshenziswe kakhulu ekukhiqizeni amafutha okugcoba amelana nezinga lokushisa eliphezulu. Ngenxa yokuhambisana kwayo nezindawo ezisezingeni eliphezulu, isebenza njengesisekelo esihle kakhulu sezigcobo embonini yezimoto kanye ne-aerospace. Imvelo yayo eqinile ngokushisa ivumela ukubekezelelana okukhulu ekushiseni okuphezulu ngokungqubuzana okuncishisiwe nokuguga kuyilapho iqinisekisa ukwethembeka nokusebenza.
Enye indawo lapho i-sebacic acid ithola khona ukusetshenziswa iwukwenza izinto ezinamathelayo namakhemikhali akhethekile. Isetshenziswa kakhulu ezintweni ezinamathelayo ngenxa yokumanzisa kwayo okuhle nokungena kwayo. I-Sebacic acid isetshenziselwa ukukhiqiza izinto ezinamathelayo ezisebenza kahle kakhulu ngoba ingathuthukisa izakhiwo zokunamathisela ze-adhesive.
I-Sebacic acid nayo isetshenziswa njenge-corrosion inhibitor ekwelapheni kwamanzi nasekukhiqizeni uwoyela. Ukusebenza kahle kwayo ekuvimbeleni ukugqwala kanye ne-oxidation kuyenza ilungele amapayipi nezinye izinto ezisetshenziselwa ukuthutha nokucubungula uwoyela negesi yemvelo.
Ngenxa yohlamvu lwayo lwekristalu olumhlophe, i-sebacic acid ingabonakala kalula kwamanye amakhemikhali. Lokhu kwenza kube ukufakwa okukhangayo embonini yezemithi njenge-excipient. Ingasetshenziswa njenge-diluent, binder kanye ne-lubricant ekwenzeni amafomu emithamo ahlukene njengamaphilisi, amaphilisi, nama-suppositories.
Sengiphetha, ukusebenzisa izinto ezihlukahlukene kwe-sebacic acid kanye nohlu olubanzi lwezinhlelo zokusebenza kuyenza ibe umkhiqizo okhangayo kakhulu ongasetshenziswa kuzo zonke izimboni eziningi kusukela kwezezimoto kanye ne-aerospace kuye kokukhiqizwa kwemithi namakhemikhali. Ukuzinza kwayo ngaphansi kwezimo ezimbi kakhulu kuyenza ibaluleke kakhulu ezimbonini eziningi ezihlanganisa ipulasitiki, uwoyela, igesi, nokwelashwa kwamanzi, kuyilapho amandla ayo okuthuthukisa ukusebenza kwama-polymers ekhombisa ukubaluleka kwawo. Sekukonke, i-sebacic acid iyisivikelo sokwakha esibalulekile semikhiqizo eminingana eseyibalulekile empilweni yesimanje.
