Thaum Tsov Rog Ntiaj Teb Zaum II, nylon tau dhau los ua cov khoom tseem ceeb hauv kev tsim cov poj niam cov hnab looj tes. Nws kuj tau siv rau hauv kev tsim cov log tsheb, lub rooj zaum thiab daim ntaub ballistic. Nws yog thawj zaug siv rau kev lag luam hauv xyoo 1938 hauv cov txhuam hniav nylon-bristled.
Thaum lub sijhawm txheej txheem polymerization, comonomers thiab stabilizers tau ntxiv los hloov kho cov khoom siv ntawm nylon. Nws kuj ua rau cov nylon tiv taus alkali thiab inorganic acids. Nws muaj zog tenacity ntawm 6 mus rau 8.5 gm / den.
Nylon muaj lub zog tensile siab thiab siv rau cov log tsheb. Tsis tas li ntawd, nws muaj zog elasticity. Ntxiv mus, nws muaj kev cuam tshuam zoo.
Nylon yog ib qho polymer ua los ntawm lactam thiab amino acid. Nws yog hygroscopic heev thiab muaj cov khoom siv hluav taws xob zoo heev. Nws kuj muaj peev xwm nqus tau zoo. Txawm li cas los xij, nws tseem kim heev.
Lub melting point ntawm nylon yog hais txog 215 degC. Nws viscosity txo qis nrog kub siab dua. Nws yog feem ntau extruded ntawm qhov kub thiab txias ntawm 260 degC.
Cov tswvcuab qis ntawm nylons yog nquag hydrolysis ntau dua los ntawm cov kua qaub muaj zog. Ntxiv mus, qhov hnyav molecular ntawm cov khoom poob thaum tawm tsam. Thaum lub sij hawm kub nias txheej txheem, entangled carbon fibers muaj ib tug zoo thermal bonding nyhuv.
