Nws cov tub ntxhais yog nyob rau hauv precisely compounding ob los yog ntau tshaj polymer melts nrog cov khoom sib txawv (xws li ib tug siab - lub zog reinforcement txheej, corrosion- resistant sab hauv thiab txheej txheej, los yog ib tug siab -txheej txheej nruab nrab) nyob rau hauv ib tug molten lub xeev siv ib tug txheej ntawm cov cuab yeej, thiab extruding lawv nyob rau hauv ib kauj ruam mus ua hauj lwm cov yeeb nkab.
Txhawm rau ua kom tiav lub hom phiaj no, cov ntsiab lus tseem ceeb ntawm cov txheej txheem yog sib cuam tshuam:
Ua ntej thiab foremost, cov khoom tsim thiab kev xaiv tsim lub hauv paus pob zeb. Nws yog ib qho tseem ceeb rau kev tshawb fawb txog kev ua haujlwm ntawm txhua txheej (xws li, corrosion resistance rau lub puab txheej, siab bearing rau nruab nrab txheej, thiab hnav tsis kam rau txheej txheej), thiab daws qhov teeb meem ntawm interfacial compatibility ntawm cov khoom sib txawv nrog kev pab ntawm additives xws li compatibilizers. Qhov no yog lub hauv paus tshuaj rau kev ua kom cov kav dej tsis txhob delaminate thaum lub sijhawm ua haujlwm ntev -.
Thib ob, precision co-extrusion cov cuab yeej yog cov khoom siv tseem ceeb rau kev paub txog lub tswv yim no, qhov tseem ceeb ntawm qhov uas muaj nyob rau hauv kev nruab nrog ntau yam ntawm nws tus kheej tswj extruders thiab multi- txheej co-extrusion tuag lub taub hau hailed li "lub siab" ntawm lub system. Tus khiav tsim nyob rau hauv lub taub hau tuag yuav tsum xyuas kom meej tias cov polymer melts ntawm txhua txheej converge kom raug ntawm predetermined txoj hauj lwm nrog uniform siab, txaus tus nqi thiab kub. Advanced tuag hau kuj tau nruab nrog kev ywj pheej nruab nrab hloov ua haujlwm kom zoo - kho qhov sib txawv thiab phab ntsa tuab ntawm cov kav dej hauv lub sijhawm.
Thib peb, kev tswj xyuas meej ntawm cov txheej txheem tsim khoom yog tus yuam sij rau kev txhais cov thev naus laus zis no rau hauv siab - cov khoom zoo. Qhov no yuav tsum muaj kev sib koom tes ua kom zoo dua qub thiab kev tswj xyuas ruaj khov ntawm qhov kub ntawm txhua qhov extruder (kom tiv thaiv kom tsis txhob degradation ntawm tshav kub- cov ntaub ntawv rhiab), ntsia hlau tig ceev (kom meej meej tswj lub ntim extrusion thiab piv ntawm txhua txheej), yaj siab, nrog rau lub tshuab nqus tsev sizing thiab staged txias txheej txheem. Kev hloov pauv hauv ib qho kev ntsuas yuav ua rau muaj kev cuam tshuam ntawm kev sib tshuam thiab cov phab ntsa tsis sib xws.
Thaum kawg, niaj hnub tshuaj xyuas hauv online thiab automation systems yog ib qho tseem ceeb txhais tau tias kom muaj kev ruaj ntseg thiab sib xws. Los ntawm kev sib koom ua ke ntawm ultrasonic thickness ntsuas, laser txheej txoj kab uas hla xyuas thiab kaw- lub voj kev tawm tswv yim, tiag- lub sijhawm saib xyuas thiab kev hloov kho tsis siv neeg cov qauv tuaj yeem ua tiav, txo tib neeg kev ua yuam kev thiab yog li ua tau zoo ua ntau- txheej cov kav dej sib xyaw nrog cov qauv tsis tu ncua thiab kev ua haujlwm zoo heev.
