Nylon tsis yaj zoo li lwm cov hluavtaws fibers; Hloov chaw, nws zoo li yaj thiab hlawv ib txhij. Nylon yog cov thermoplastic polymer, uas txhais tau hais tias nws softens thaum raug tshav kub tab sis tsis muaj qhov sib txawv melting point zoo li thermosetting yas. Thaum nylon raug nplaim taws lossis kub kub, nws thawj zaug softens thiab ces pib decompose thiab hlawv.
Nov yog qhov tshwm sim thaum nylon raug tshav kub los yog qhib nplaim taws:
- softening:Nylon pib soften thaum nws mus txog nws qhov decomposition kub, uas feem ntau yog nyob rau hauv thaj tsam ntawm 160 degree mus rau 260 degree (320 degree F txog 500 degree F), nyob ntawm seb hom nylon thiab nws qib. Thaum lub sij hawm no, cov nylon yuav pliable thiab yuav deform.
- Decomposition:Raws li qhov kub thiab txias nce ntxiv, nylon undergoes thermal decomposition. Cov txheej txheem no suav nrog kev rhuav tshem cov tshuaj lom neeg hauv cov saw hlau polymer, tso tawm ntau yam tsis muaj zog thiab tsim cov char. Cov ntaub ntawv nylon yuav qaug zog thaum lub sijhawm no.
- combustion:Yog hais tias lub tshav kub nyob twj ywm, cov volatile tebchaw tso tawm thaum lub sij hawm decomposition yuav ignite, ua rau combustion. Nylon yuav hlawv thiab tsim cov nplaim taws, nrog rau kev tso pa tawm thiab cov pa taws uas tsis zoo.
Cov txheej txheem combustion ua kom muaj cua sov, lub teeb, thiab cov yam ntxwv ntawm kev kub hnyiab. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias nylon tuaj yeem tua nws tus kheej thaum lub tshav kub raug tshem tawm, tab sis yog tias cov cua sov ua kom ruaj khov, nws tseem yuav hlawv.
Nylon tus cwj pwm thaum raug tshav kub ua rau nws tseem ceeb rau kev ceev faj thiab ua raws li cov lus qhia kev nyab xeeb thaum ua hauj lwm nrog cov ntaub ntawv nylon los yog textiles, tshwj xeeb tshaj yog nyob rau hauv lub caij ntuj sov los yog qhib nplaim taws. Kev ntsuas qhov cua kom zoo thiab kev nyab xeeb hluav taws yuav tsum tau txiav txim siab thaum siv cov khoom siv nylon lossis cov ntaub.
