Feem ntau siv cov txhuam hniav hauv kev tsim cov txhuam hniav yuav tsum yog cov nylon bristles, cov khoom tseem ceeb ntawm cov nylon bristles yog polyamide (Nylon), cov lus Askiv lub npe Polyamide (PA luv luv), yog cov ntsiab lus dav dav rau cov thermoplastic resins uas muaj cov pab pawg amide rov qab - [NHCO ]- ntawm cov saw tseem ceeb ntawm cov molecule.Nws suav nrog aliphatic PA, aliphatic-aromatic PA thiab aromatic PA, ntawm cov uas muaj ntau yam, ntau ntau lawm thiab ntau yam kev siv, thiab nws lub npe yog txiav txim los ntawm tus naj npawb ntawm carbon atoms nyob rau hauv cov hluavtaws monomer.

Lub ntsiab ntau yam ntawm nylon yog nylon 6 thiab nylon 66, uas yog cov tseem ceeb kiag li.Muaj ntau ntau yam kev hloov kho nylon, xws li cov nylon reinforced, monomer cam khwb cia nylon (MC nylon), reactive txhaj molded (RIM) nylon, aromatic nylon, pob tshab nylon, siab cuam tshuam (super tawv) nylon, electroplated nylon, hluav taws xob. conductive nylon, nplaim retardant nylon, nylon blends nrog lwm yam polymers thiab alloys, thiab lwm yam. Lawv tau dav siv los hloov cov khoom siv tsoos xws li hlau thiab ntoo, thiab ua cov ntaub ntawv ntawm txhua yam.

Nylon yog qhov tseem ceeb tshaj plaws engineering yas, nrog cov khoom ntim ntau tshaj plaws ntawm tsib sab saum toj engineering yas.Nylon muaj zog txhua yam, siab softening point, tshav kub tsis kam, tsis tshua muaj coefficient ntawm kev sib txhuam, abrasion kuj, nws tus kheej-lubricating, poob siab absorbing thiab suab dampening, roj kuj, tsis muaj zog acid kuj, alkali kuj thiab hnyav hnyav, zoo hluav taws xob rwb thaiv tsev, nws tus kheej. -extinguishing, tsis muaj tshuaj lom, tsis muaj ntxhiab, huab cua tsis zoo thiab tsis zoo dyeing.Qhov tsis zoo yog tias cov dej nqus dej yog qhov loj, uas cuam tshuam rau qhov kev ruaj ntseg thiab cov khoom hluav taws xob.Lub fiber reinforcement tuaj yeem txo cov dej nqus ntawm cov resin kom nws tuaj yeem ua haujlwm ntawm qhov kub thiab txias.Nylon muaj kev sib raug zoo heev nrog iav fibers.

Nylon 66 muaj qhov siab tshaj plaws hardness thiab rigidity, tab sis qhov phem tshaj toughness.Ntau yam nylons raug txiav txim los ntawm qhov hnyav: PA66＜PA66/6＜PA6＜PA610＜PA11＜PA12 Lub combustibility ntawm nylon yog UL94v-2 qib, cov pa index yog 24-28, qhov decomposition kub ntawm nylon yog> 299 ℃, thiab spontaneous. combustion yuav tshwm sim ntawm 449 ~ 499 ℃.Lub yaj ntws ntawm nylon yog qhov zoo, yog li phab ntsa tuab ntawm cov khoom tuaj yeem ua me me li 1 hli.
