Kub yaj nplaum nplaumyog homyas nplaum, nws lub cev lub cev tuaj yeem hloov pauv nrog qhov hloov pauv ntawm qhov kub thiab txias, tab sis nws cov khoom siv tshuaj yuav tsis hloov, yog li kub yaj nplaum nplaum muaj kev ua haujlwm zoo ib puag ncig.Kub yaj nplaum nws tus kheej yog cov khoom, uas yog nyiam los ntawm qhov zoo ntawm kev ntim khoom yooj yim, kev thauj mus los, kev cia khoom, cov txheej txheem tsim khoom yooj yim, tus nqi ntxiv, kev sib koom ua ke siab zog thiab ceev ceev.
Peb cov tsos ntawm kub yaj nplaum nplaum feem ntau yog dawb, thiab qee qhov yog pob tshab.Yog li dab tsi peb yuav tsum ua kom kub yaj nplaum nplaum nplaum thiab dawb?Subang pom zoo kom ntxiv cov dej me me thaum lub sijhawm tsim khoom.Kub yaj nplaum nplaum fluorescent whitening tus neeg sawv cev.
Ethylene thiab vinyl acetate yog cov txheej txheem ntawm cov nplaum kub yaj, uas yog copolymerized nyob rau hauv qhov kub thiab txias, uas yog EVA resin.EVA resin yog lub ntsiab tseem ceeb rau kev ua cov nplaum nplaum kub, thiab qhov kev ua tau zoo ntawm cov nplaum nplaum yog txiav txim siab los ntawm kev faib ua feem thiab zoo ntawm cov resin.Txawm li cas los xij, nws tseem ceeb heev uas yuav tau xaiv EVA yaj ntiv tes.Qhov me me ntawm cov ntiv tes yaj, qhov dej tsis zoo thiab lub zog ntau dua.Qhov siab dua qhov kub ntawm melting, qhov tsis zoo ntawm cov ntub dej thiab permeability ntawm adherend.Ntawm qhov tsis sib xws, yog tias lub melting Performance index loj dhau, qhov kub ntawm cov kua nplaum melting yog tsawg, qhov fluidity yog qhov zoo, tab sis lub zog sib txuas yog txo.Kev xaiv ntawm nws cov pab pawg, nws yog qhov zoo tshaj plaws los ua kom qhov sib piv ntawm ethylene thiab vinyl acetate tsim nyog.
Ua ntej, tsim cov qauv tsim nyog nrog cov khoom sib txawv ntawm cov khoom siv raw, ntxiv cov khoom siv kub yaj nplaum nplaum rau cov tshuaj tiv thaiv lub hwj, thiab sib tov ib qho tsim nyog ntawm cov tshuaj fluorescent whitening tus neeg sawv cev rau kub yaj nplaum nrog cov khoom siv raw khoom sib npaug hauv cov txheej txheem tsim khoom, feem ntau yog ib qho. ton ntawm raw khoom Ntxiv txog 200g tuaj yeem ua tiav cov txiaj ntsig zoo heev.
Ua kom kub kom yaj nws thiab do zoo.Tom qab ntawd txias cov roj hmab melted nyob rau hauv cov tshuaj tiv thaiv kettle rau ib tug tej yam kub thiab muab tso rau hauv lub khiav extruder.Lub extrusion ceev ntawm lub extruder tuaj yeem xaiv raws li ntau hom roj hmab.
Lub extruder nyem cov nplaum kub yaj rau hauv lub tank dej los ntawm ib lub voj voog extrusion qhov ntawm lub taub hau extrusion.Cov nplaum nplaum kub yaj yog tam sim ntawd zoo li thaum nws ntsib dej txias.Cov nplaum nplaum yog ua ntej txias thiab zoo li tus los ntawm thawj lub tank dej txias.Lub tshuab traction ntawm lub tshuab ua kua nplaum nkag mus rau hauv lub tank dej txias thib ob, thiab cov qauv ua kua nplaum tau ua kom txias thiab zoo li hauv lub tank dej txias thib ob.Kev khiav ceev ntawm cov nplaum nplaum nyob rau hauv lub tank dej yog tswj los ntawm extrusion ceev ntawm lub extruder, kom lub tshuab traction Lub rub ceev yog synchronized nrog extrusion ceev ntawm lub extruder.
Kho thiab tswj kev sib raug zoo ntawm extrusion ceev, txias qhov chaw ceev thiab traction ceev, thiab ces slitting thiab packing lub txias kub yaj nplaum nplaum rau hauv cov khoom tiav.Tus nqi whiteness ntawm kub yaj nplaum tom qab ntxiv covfluorescent whitening tus neeg sawv cevyog pom tseeb txhim kho los ntawm ob peb lub ntsiab lus, thiab nws tsis yooj yim rau daj nyob rau theem tom ntej.
