Cov txheej txheem los tiv thaiv Plastisol Ignition thiab Blistering los ntawm Optimal Rhaub Txheej
Bubbling, nto scorching, thiab cov voids sab hauv yog cov tsis xws luag nyob rau hauv plastisol txhaj moulding, uas ua rau cov txiaj ntsig tseem ceeb rau cov tuam txhab tsim khoom. Feem ntau ntawm cov kws tshaj lij hais txog cov teeb meem no rau cov khoom paug hauv cov khoom siv raw lossis tsis txaus txhaj tshuaj tshaj tawm, thaum tsis quav ntsej txog qhov teeb meem tseem ceeb ntawm kev tsim hluav taws xob tsis zoo. Lub hauv paus tseem ceeb uas ua rau muaj kev puas tsuaj rau cov cua sov hauv plastisol yog qhov kub thiab txias hauv cheeb tsam tsis sib xws, uas tuaj yeem hais tau zoo nrog kev xaiv kom raug thiab kev npaj ntawm cov txheej txheem cartridge rhaub.
Power density alignment is the fundamental principle to eradicate plastisol combustion issues. Cartridge rhaub ua haujlwm rau kev txhaj tshuaj plastisol yuav tsum ua raws li cov qauv kev lag luam ntawm 5-7 W / cm². Lub zog ceev tshaj 7 W / cm² ua rau muaj kev kub ntxhov hauv cheeb tsam. Qhov ntsuas kub tam sim ntawd ua los ntawm lub tshuab hluav taws xob ntau dhau ntawm lub tshuab hluav taws xob ntau dhau qhov kev txwv thermal breakdown ntawm plastisol, ua rau cov khoom siv carbonization, deg xim, thiab cov cim hlawv me me ntawm cov khoom kawg. Xws li qhov tsis zoo yog irreparable thiab ua rau cov khoom pov tseg.
Kev ua kom cua sov tsis txaus vim qhov tsawg - cov khoom siv cua sov muaj peev xwm yog qhov laj thawj tseem ceeb rau plastisol bubbling. Thaum lub hwj chim ceev ntawm lub tshuab cua kub hauv qab 5 W / cm², qhov kub ntawm cov pwm nce zuj zus thiab ua tsis tau raws li qhov kub thiab txias tam sim ntawd. Cov dej noo thiab cov khoom tsis zoo nyob hauv plastisol tseem tsis tau kho thiab tsis tuaj yeem tshem tawm tag nrho thaum lub sij hawm molding txheej txheem, uas ua rau tsim cov npuas npuas thiab pitted nto thaum txias ntawm cov khoom. Cov khoom nthuav tawm bubbling imperfections muaj qhov txo qis ntawm cov qauv kev ncaj ncees thiab subpar nto zoo, yog li tsis ua raws li cov txheej txheem kev lag luam.
Prudent installation kev sib koom ua ke txhim kho kev ua haujlwm ntawm lub tshuab rhaub dej kub thiab txo cov molding imperfections. Qhov tsis haum ntawm lub tshuab rhaub cartridge thiab cov pwm apertures tsim cov cua voids uas cuam tshuam cov thermal conduction. Txawm hais tias muaj qhov sib npaug ntawm qhov sib npaug ntawm 5-7 W / cm², qhov kub tsis tu ncua yuav ua rau ob qho tib si hauv cheeb tsam overheating thiab thaj chaw ntawm cov cua sov tsis txaus. Qhov kev sib raug zoo ntawm qhov kev sib raug zoo tau lees paub kev sib raug zoo ntawm lub tshuab cua sov thiab cov pwm hlau, ua kom yooj yim hloov pauv sai thiab zoo sib xws thoob plaws hauv tag nrho cov pwm kab noj hniav.
Kev tswj xyuas qhov kub thiab txias cuam tshuam nrog lub tshuab hluav taws xob cartridge kom paub meej qhov kev saib xyuas thermal. Cov txheej txheem kub tswj tau zoo dua tsim nyog rau plastisol molding piv rau kev ua haujlwm kub siab mus tas li -. Preheating ntawm qhov kub tsis tshua muaj tshem tawm cov khoom siv sab hauv thiab cov khoom tsis sib haum xeeb, qhov nruab nrab- qhov kub thiab txias ua kom sov ua tiav homogenous gelation. Qhov tso zis thermal zoo ib yam ntawm lub tshuab tso cua sov tso cai lav seamless hloov ntawm cov cua sov theem, tiv thaiv qhov kub hloov pauv sai uas tuaj yeem ua rau cov khoom puas tsuaj.
Eradicating flaws xws li hlawv thiab bubbling nyob rau hauv plastisol nyob ntawm tus txheej txheem cua sov txheej txheem es tsis txhob ntawm cov txheej txheem txuas ntxiv teeb meem. Lub 5-7 W / cm² cartridge rhaub yog qhov tsim thiab txhim khu kev qha cua sov rau cov ntawv thov kev txhaj tshuaj plastisol. Ntau yam khoom configurations thiab pwm tsim yuav tsum tailored cua sov parameter dlhos thiab layout lub koom haum. Cov kev daws teeb meem cua sov tuaj yeem daws qhov teeb meem ntawm cov thermal-txog molding imperfections thiab txhim kho tag nrho cov kev ua tau zoo.
