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.

Cov av nplaum polymer twg yog qhov zoo tshaj plaws rau sculpting?
Sculpey yog qhov kev xaiv nrov rau nws lub zog thiab cov xim zoo nkauj. Nws tau tsim los ntawm cov neeg ua yeeb yam cov tswv yim ntawm cov av nplaum zoo meej polymer. Txawm hais tias nws yuav zoo li tawv thaum xub thawj, nws yooj yim siv thiab muaj zog dua Sculpey III.
Lub polymer twg muaj kev sib txuas ntawm kev sib txuas?
Ntawm no, los ntawm cov kev xaiv muab Nylon-6, 6 yog cov polymer uas muaj kev sib txuas ntawm amide. Yog li, nylons tseem hu ua polyamides vim lawv cov yam ntxwv amide pawg hauv cov pob txha caj qaum. Amide pawg nyob rau hauv nylon molecules yog heev polar, thiab tsim hydrogen bonding ib leeg .
Yuav ua li cas cuam tshuam cov polymer sib txuas?
Lawv tuaj yeem npaj tau los ntawm kev sib xyaw ob lub monomers, uas yog tom qab (thiab feem ntau ib txhij) polymerized thiab cross-linked (Fig. 1a), lossis los ntawm dissolving ib monomer hauv lub network polymer; tus qub ces reacted los ua tus thib ob interpenetrating network (Fig.
Puas yog triglyceride yog polymer?
Fatty acids tsim ntau complex lipid polymers hu ua triglycerides, triacylglycerols lossis triacylglycerides thaum txhua qhov sib koom ua ke oxygen molecule bonds rau carbon uas yog ib feem ntawm glycerol molecule. … Triglycerides kuj muaj nyob rau hauv cov khoom noj, tshwj xeeb tshaj yog cov khoom tsiaj .
Puas yog av nplaum polymer nyuaj thaum ci?
Muaj polymer cua qhuav av nplaum uas dries ntawm chav tsev kub, tab sis nws muaj sijhawm ua haujlwm tsawg. Thiab qhov ntawd ua rau qee cov tswv yim ua tsis tau, xws li tsim cov kab uas muaj cov kab sib kis. Feem ntau cov polymer 'qhov cub av nplaum' hardens thiab kho nrog cua sov txaus rausijhawm ntev txaus .
