Polyphenylene sulfide PPS feem ntau yog tsim los ntawm txhaj, extrusion, nias, txau, thiab cov zoo li. PPS rau kev txhaj tshuaj molding feem ntau muaj kev ntsuas pib ntawm 10-100 g / min, thiab feem ntau tau qhab nia nrog ntxiv fiber ntau ntxiv los yog kev hloov puv tswb. Lub tshuab txhaj tshuaj yuav tsum siv feem ntau siv lub hau ntswj hom tshuaj, uas yuav tsum tau muaj cua sov ntawm 350 ° C thiab ib qho kev txhaj tshuaj ntawm 150 MPa. Lub nozzle yuav tsum yog qhov locking tiv thaiv kom txhob muaj qhov tseeb. Cov pwm yuav tsum tau muab rhaub, thiab cov khoom txhaj tshuaj ntawm cov pwm tsis tshua muaj pwm tsis tshua muaj crystallinity, thiab xav tau kev pab tom qab kho kom nce tau qhov kev ua tau zoo ntawm qhov khoom. High crystallinity khoom yog tau ntawm cov pwm kub.
Feem ntau yog siv cov txheej txheem kev txhaj tshuaj yog: thawv txias 300-340 ° C, txhaj tshuaj 70-140 MPa, pwm kub 120-200 ° C, tuav lub sijhawm 30-120 s, molding shrinkage 0.2% mus 0.8%. PPS compression molding yuav tsum tau ua ntej ci ci cov hmoov av (qhov pib ntawm qhov siab tshaj 200) ntawm 250 ° C rau 2 h, tom qab ntawd sib tov nrog tus muab tub lim, ces ntxiv rau pwm thiab khaws cia ntawm 370 ° C rau 30-40min. Tom qab noj, nws tau muab tso rau ntawm ib qho txias txias thiab siab-molded, thiab lub siab yog txog 10 MPa, thiab nws tau cia txias rau 150 ° C, thiab ces demolded. Cov khoom yog ces tom qab kho ntawm 200-250 ° C, thiab lub sij hawm kho lub sij hawm nyob ntawm lub thickness ntawm cov khoom.
Txau ntawm PPS yog tsuas yog raws li electrostatic hmoov txheej. Ua ntej txau, cov hlau ua haujlwm yuav tsum tau degreased, xuab zeb blasted thiab sib liam kho kom zoo rau kev ua tiav ntawm qhov workpiece thiab PPS. Tom qab ntawd ua ntej cua sov ua haujlwm ntawm 370-400 ° C rau 10-20min, muab tshuaj tsuag PPS mus rau saum npoo ntawm cov khoom ua haujlwm nrog rab phom. Txhua lub tshuaj tsuag yuav tsum tsis txhob tuab heev, thiab rov ua haujlwm 3-4 zaug. Tom qab qib siab thiab muab khoom tiav, nws yuav ua kom ncaj. Glossy txheej, tag nrho cov tuab ntawm txheej yuav tsum tsis pub tshaj 0.5 hli.
