Peb feem ntau siv nylon pas nrig PA6 cov khoom siv crystalline thermoplastic, cov khoom siv nylon yooj yim nqus dej, muaj cov pab pawg hydrophilic (acylamino).　

Nyob rau hauv cov ntaub ntawv ntawm crystalline polymers, lub txias ceev heev thaum lub sij hawm extrusion txheej txheem tiv thaiv cov khoom los ntawm ib txwm crystallizing thiab teeb, uas ua rau muaj zog nyob rau hauv cov kev ntxhov siab nyob rau hauv cov khoom.Nyob rau hauv cov ntaub ntawv ntawm nylon rods uas tsis tau "tempered", cov macromolecules tseem zoo li txav mus rau hauv ib txwm oriented, crystalline yam tom qab teeb tsa, uas ua rau muaj kev ntxhov siab ntxiv hauv cov khoom.Yog li ntawd, qhov brittleness ntawm nylon qhov chaw uas tsis muaj cov txheej txheem boiling yog siab heev, thiab nws yog ib qho yooj yim mus poob los yog tawg thaum nws raug rau sab nraud quab yuam.　

Yog li, yuav ua li cas yog tias peb cia cov nylon macromolecules uas twb tau tsim lawm ib txwm muaj kev taw qhia thiab crystallize kom tshem tawm cov kev ntxhov siab sab hauv kom ntau li ntau tau?Qhov ntawd yog qhov peb hu ua boiling, thiab cov txheej txheem boiling yeej zoo ib yam li peb cov hlau "tempering" txheej txheem.Uas yog cia cov nylon qhov chaw nyob rau hauv ib tug tej yam dej kub, thiaj li hais tias nws sab hauv macromolecules zoo li tej yam ntuj tso orientation thiab ua kom tiav qhov sib npaug ntawm sab hauv crystallization thiab decrystallization, thiaj li mus tshem tawm nws cov kev ntxhov siab.Qhov kev ua tau zoo nyob rau sab nraud yog: qhov tawv ntawm cov nylon feem ntau txhim kho, thiab cov brittleness yog qhov yooj yim tshem tawm.　

　　Yog vim li cas boil nws nrog dej?Qhov ntawd yog vim tias nylon muaj cov pab pawg hydrophilic - acylamino pawg, uas ua rau nylon nqus dej yooj yim, tab sis tom qab nylon absorbs qee cov dej, nws pab nws sab hauv macromolecule orientation thiab crystallization txav.

　　Qhov kub thiab lub sij hawm zoo dua rau cov nylon bushings thiab nylon qhov chaw: 90-100℃, 2-8 hnub.Hauv qab 90 degrees, cov nyhuv tsis zoo, thiab ntau dua 8 teev, yuav tsis muaj txiaj ntsig zoo dua.Hais txog kev ua haujlwm ntawm tus nqi, cov txheej txheem saum toj no zoo dua.Huafu Nylon tsim cov tawv tawv dub MC nylon bushings nrog 5-15% molybdenum disulfide, 3% toughening tus neeg sawv cev, MC casting hom "Huafu" nylon ua cov khoom siv hauv paus, ntxiv txhua yam kev hloov pauv hauv cov txheej txheem tshuaj tiv thaiv, ua rau nws hnav-tiv taus. , corrosion-resistant, laus-resistant, nws tus kheej-lubricating, vibration-absorbing thiab suab nrov-absorbing.Nws muaj superior hnav tsis kam, cuam tshuam tsis kam, tsis yooj yim rau tuav lub ncej, fusion, tsis txhob ua mob rau cov ntawv xov xwm, lub voj voog ntev lubrication, ntxiv iav fiber ntau hlaws, graphite thiab lwm yam khoom siv tshuaj ua kom nws lub cev muaj zog dua hnav-tiv taus, kev pabcuam ntev dua. lub neej, feem ntau ntawm cov cuab yeej siv tshuab cog los ua kev txhawb nqa kev siv cov txiaj ntsig zoo.Peb zoo siab txais tos cov neeg los ntawm txhua qhov chaw tuaj xyuas peb lub tuam txhab thiab nug!
