I-2-Nitropropane (i-Dimethylnitromethane)

Amakhemikhalini-atures

I-2-Nitropropane eyaziwa nangokuthi i-dimethylnitromethane noma i-isonitropropane iwuketshezi olungenambala, olunamafutha olunephunga elimnandi nelithambile. Luyavutha futhi luyancibilika emanzini. Luphinde luncibilike ezinyibilikisini eziningi eziphilayo okuhlanganisa ne-chloroform. Umhwamuko walo ungakha ingxube eqhumayo nomoya. Isetshenziswa njenge-cosolvent kupende ukuthuthukisa ukumanzisa kwe-pigment, izakhiwo zokugeleza, kanye nokucutshungulwa kwe-electrostatic; futhi kunciphisa isikhathi sokomisa upende.

Izicelo

I-2-Nitropropane isetshenziswa kakhulu njengesithako samakhemikhali nezinto zokumboza eziphilayo; ngama-resin e-vinyl, upende we-epoxy, i-nitrocellulose, kanye nerabha ene-chlorine; ekunyatheliseni uyinki, izinamathiseli, kanye nokunyathelisa njengoyinki we-flexographic; ukulungiswa ngezimpawu zethrafikhi emigwaqweni nasemigwaqweni emikhulu; ukwakhiwa kwemikhumbi; kanye nokugcinwa okuvamile. Iphinde isetshenziswe ngokulinganiselwe njengesithako sokususa upende ne-varnish. I-2-Nitropropane isetshenziswa futhi njengesithako ezimbonini zokucubungula ukudla ukuze kuhlukaniswe uwoyela wemifino ogcwele kancane.

Isikhathi sokuphelelwa yisikhathi

Ngokusho kokuhlangenwe nakho kwethu, umkhiqizo ungagcinwa izinsuku ezingu-12.izinyanga kusukela osukwini lokulethwa uma zigcinwe ezitsheni ezivalwe kahle, zivikelwe ekukhanyeni nasekushiseni futhi zigcinwe emazingeni okushisa aphakathi kuka-5 -30°C
