Phom paj rwb tseem hu ua nitrocellulose. Phom paj rwb yog nitrating cellulose thiab yog npaj los ntawm exposing cellulose rau nitrating sib tov. Thaum lub sij hawm nitration, hydrogen atom ntawm hydroxyl pawg hauv cellulose polymer yog hloov los ntawm nitro pawg. Yog li, rab phom paj rwb yog a polymer
YPuas yog nitrocellulose yog polymer?
Nitrocellulose muaj qhov zoo sib xws rau paj rwb (dawb thiab fibrous kev ntxhib los mos). Nws yog a nitrate cellulose ester polymer nrog β (1 → 4) bonds ntawm monomers, tsim los ntawm nitration ntawm cell…
Guncotton yog dab tsi?
Nitrocellulose (tseem hu ua cellulose nitrate, flash paper, flash paj rwb, guncotton, pyroxylin thiab flash hlua, nyob ntawm daim ntawv) yog ib qho hluav taws kub heev uas tsim los ntawm nitrating cellulose los ntawm Kev sib xyaw ntawm nitric acid thiab sulfuric acid.
Guncotton hauv chemistry yog dab tsi?
Guncotton, los yog nitrocellulose (tseem hu ua trinitrocellulose thiab cellulose nitrate) yog ib tawg me me, siv hauv foob pob hluav taws, tshuab, luam ntawv number case bases, tawv xov, thiab celluloid (a kev sib xyaw ntawm nitrocellulose thiab camphor; thawj zaug siv los tsim cov pob billiard).
YPuas nitrocellulose yog tshuaj?
nitrocellulose, tseem hu ua cellulose nitrate, kev sib xyaw ntawm nitric esters ntawm cellulose, thiab cov nplaim hluav taws kub heev uas yog cov khoom tseem ceeb ntawm cov hmoov phom niaj hnub thiab tseem ua haujlwm hauv qee cov lacquers. thiab pleev xim.
