Azobisisoptonittonitrile: Zvivakwa, Zvikumbiro uye Nyevero dzekuchengetedza

Nguva pfupi yadarika, Azebisisohptonitrile yakambouya zvakare muziso reruzhinji. Ichi chinhu chemakemikari, nezita reChirungu 2,2--azobis- (2,4-dimethylvaleronitrile), anoonekwa semachena makristasi, nenzvimbo yekunyungudika kubva makumi mana kusvika makumi manomwe kusvika makumi manomwe kusvika makumi manomwe Iyo inguva-inosemesa inomira ine simba rekushandisa ye122 kj / mol. Inonyungudika mune organic sol sol, solanol, toluene uye acetone, asi kusakwana mumvura. Tembiricha yechidhori pagumi-maawa hafu-hupenyu ndeye 51 ℃ (muToluene).

Azobisisoptonittonitnitrile inonyanya kushandiswa mu bulk polmerization, kumiswa polmerization uye mhinduro polymerization, uye inoshandiswa zvakanyanya mukugadzira maindasitiri uye kutsvakwa kwesainzi. Sezvo kuora kwawo kuri kungoita kwekutanga-kurongeka kwekuita, kugadzira chete rudzi rwemhando yemahara pasina maitiro, iyo yakagadzikana muzvisikwa uye zvakanakira kuchengetedza uye kufambisa. Nekudaro, zvinofanirwa kucherechedzwa kuti panguva yekufambisa, inoda kuti irambe uye inodzivirirwa kubva mukukakavara zvakanyanya uye kuhukura, zvimwe zvinogona kukonzera kuputika.

Achiyeuka mangwanani-ngwanani kwaJuly 22, 2011, murairidzi weDeCK anofamba achibva kuWeihai, Shandong to changsha, Hunan paBeijing-Zhuhai Expressway yakangoerekana yabata moto. Moto wacho wacho waityisa zvekuti wakapisa mudzidzisi wepazasi. Dambudziko iri rakati rinoda kufuma 41 uye vakakuvara vanhu 6, vane munhu mumwe munhu akakuvara zvakanyanya. Mushure mekuferefeta, chikonzero chetsaona ndechekutakura zvisiri pamutemo uye zvekufambisa zvezvikamu zvinopisa zvechigadzirwa Acabisisohehptonitrile pane tsaona yemotokari. Aya makemikari ane ngozi akangoerekana aputika uye akapiswa pasi pezviito zvezvinhu zvakaita sekusungwa, kupokana uye kusunungurwa kubva kuinjini, zvichitungamira kune ino chiitiko chinoshungurudza. Pashure pacho, vanhu vane mutungamiriri vakakodzera vakasungwa uye vakasungwa nematsotsi zvinoenderana nemutemo. MunaDecember 2013, vanhu vakapindirana vevanhu veXinyang, Henan Province Mutongo wetsaona iyi, vatongerwe vane mutongo wezvemhosva kuti vape mhosva yeruzhinji nzira uye netsaona huru dzakaipa.

Chiitiko ichi chakaridza ruzha rwekuchengetedza kwekufambisa uye kushandiswa kweAzobisisohistsonitrile. Mabhizinesi akakodzera uye vashandi vanofanirwa kutevedzera zvakanyatsonaka nemirairo yakakodzera kana ichienda kuti kufambisa uye mamiriro ekuchengetedza anosangana nezvinodiwa, uye dzivisa kudzokorora kwenhamo dzakafanana. Panguva imwecheteyo, veruzhinji vanofanirawo kuwedzera kunzwisisa kwavo kwemakemikari ane ngozi uye kusimudza ruzivo rwavo rwekuchengetedza.
