Khoom thiab txhaj Moulding Technology ntawm PA

PA- polyamide, tseem hu ua nylon, yog ib lo lus dav dav rau chav kawm loj ntawm amide polymers. Cov feem ntau cov yuav tau PA6, PA66, thiab PA1010. Tsis ntev los no, nrog txoj kev loj hlob ntawm I / T kev lag luam, kev siv hom tshiab ntawm polyamide-PA46 tau nce ntau, uas yog siv los hloov LCP (kua siv lead ua kua polymer) los tsim cov ntsaws ntawm cov khoos phis tawm. Vim tias PA muaj cov khoom siv zoo hauv lub cev, ua kom nruj, cuam tshuam kev cuam tshuam, hnav tsis kam, nws tus kheej lubrication, nplaim taws rov qab, rwb thaiv tsev thiab lwm yam ntxwv, nws tau dav siv hauv kev kho tsheb, tshuab, hluav taws xob, ntsuas, tshuaj lom neeg thiab lwm yam, xws li lub zog, pulleys. , cov kabmob, cov kabmob, cov plhaw hav zoov, cov thawv ntim, txhuam, zippers thiab lwm yam. PA6, PA66, PA46 yog aliphatic polyamides, yog cov kab hluav taws xob polymers, lawv cov qauv tsim cov qauv muaj qhov muaj zog ntau hom polar amide pab pawg, yog li nws muaj qhov siab ntawm cov khoom siv crystallization. Cov khoom ntawm PA cov khoom yog nyob ntawm lawv cov crystallization morphology thiab crystallinity. Cov txheej txheem ua haujlwm muaj qhov cuam tshuam rau cov siv lead ua morphology thiab crystallinity. Kev ua cov txheej txheem sib txawv, qhov hloov kho crystallization ntawm PA cov khoom tuaj yeem ncav cuag 40%, qhov txias txias ntawm cov khoom lag luam yog qeeb, qib ntawm crystallization yog siab, thiab cov siv lead ua morphology ntawm loj dua yog tsim. Qhov nqus dej kuj tseem muaj cov ntxim rau cov crystallinity. Tsis tas li ntawd, PA yuav tsim qhov tseeb ntawm kev yoog raws vim qhov ntws thiab shear hauv cov txheej txheem machining, uas ua rau lub zog tsis sib xws ntawm cov khoom muaj zog, lub zog raws cov kev taw qhia qhov kev ua tau zoo dua qhov ntawd hauv qhov kev taw qhia tsis yog, thiab cov kev taw qhia kuj tau txais txiaj ntsig zoo rau cov txheej txheem crystallization. Qhov zoo tshaj yuav tsum raug txiav txim siab hauv qhov tuag desig n.
