Nylon raj, siab -kev ua tau zoo yas raj siv dav hauv kev lag luam tsheb, tshuab, thiab tshuaj lom neeg, muaj cov txheej txheem tsim khoom uas nws qhov kev nruj thiab kev txawj ntse ncaj qha cuam tshuam cov khoom zoo thiab kev ua haujlwm. Kev tsim cov nylon raj feem ntau yog cov kauj ruam tseem ceeb xws li kev npaj cov khoom siv raw, extrusion molding, txias thiab shaping, traction txiav, thiab tshuaj xyuas thiab ntim. Txhua theem yuav tsum muaj kev tswj xyuas nruj kom ntseeg tau tias cov khoom tiav tiav raws li cov qauv.
Kev npaj cov khoom raw yog thawj kauj ruam hauv kev tsim khoom. Cov raj nylon feem ntau siv PA6 (Nylon 6) lossis PA66 (Nylon 66) ua cov khoom siv tseem ceeb, nrog cov yas, cov khoom siv hluav taws xob, lossis cov nplaim hluav taws xob ntxiv raws li daim ntawv thov. Cov khoom siv raw yuav tsum tau qhuav kom tshem tawm cov dej noo, tiv thaiv huab cua npuas lossis degradation thaum lub sij hawm extrusion thiab xyuas kom cov khoom ntws thiab ruaj khov.
Extrusion molding yog cov txheej txheem tseem ceeb. Cov khoom siv qhuav qhuav yog rhuab thiab yaj siv cov ntsia hlau extruder. Nyob rau hauv qhov kub thiab txias (feem ntau yog 240-280 degree) thiab siab, cov yaj raug thawb rau hauv qhov tuag. Kev tsim qauv tuag ncaj qha cuam tshuam qhov tseeb ntawm lub raj sab nraud, phab ntsa thickness, thiab txoj kab uas hla sab hauv; yog li ntawd, nws yuav tsum raug kho raws li cov specifications. Molten nylon tsim ib tug nruam tubular qauv nyob rau hauv lub pwm thiab ces nkag mus rau hauv ib tug txias system.
Kev ua kom txias thiab ua kom tiav yog ua tiav nrog dej los yog cua txias kom ua kom muaj zog sai sai ntawm qhov kub ntawm - kub yaj. Cov dej txias tso tsheb hlau luam yog txoj kev siv ntau tshaj plaws, siv cov txheej txheem dej kub tswj kom tsis txhob muaj kev ntxhov siab sab hauv los ntawm kev ua kom txias sai, uas tuaj yeem cuam tshuam rau cov khoom siv kho tshuab. Lub raj cua txias nylon yuav tsum muaj qhov ntev ruaj khov los tso lub hauv paus rau kev ua haujlwm tom ntej.
Nyob rau hauv lub traction thiab txiav theem, lub raj yog rub tawm ntawm qhov ceev ceev los ntawm lub tshuab traction kom paub meej ntev ntev. Lub zog traction yuav tsum sib npaug ntawm qhov ceev extrusion kom tsis txhob deformation lossis tawg. Tom qab ntawd, lub raj yog raug txiav rau qhov ntev ntawm lub tshuab txiav, yuav tsum tau ua kom du, burr - dawb txiav.
Thaum kawg, cov khoom tiav tau txais kev tshuaj xyuas nruj, suav nrog kev tshuaj xyuas qhov muag (smothness, tsis muaj npuas), ntsuas qhov ntev (sab nraud txoj kab uas hla, phab ntsa thickness kam rau ua), thiab kev ntsuas kev ua haujlwm (siab tsis kam, tsis kam tiv taus, tshuaj tiv thaiv). Cov khoom tsim nyog tau ntim thiab khaws cia kom ntseeg tau tias lawv tsis raug puas tsuaj thaum thauj.
Cov txheej txheem ntawm cov nylon tubes integrates cov ntaub ntawv science, mechanical engineering, thiab zoo tswj technology. Kev tswj xyuas kom zoo ntawm txhua kauj ruam yog qhov tseem ceeb los ua kom nws cov kev ua haujlwm siab thiab kev ua neej ntev.
