Weld kab yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm cov khoom yas.Piv txwv li, hauv kev lag luam tsheb, Piv txwv li, hauv kev lag luam tsheb,tsheb bumpers, Xaus Fitting, thiab lwm yam, tsis tsim nyog cov khoom yas ncaj qha ua rau lub tsheb tsis zoo thiab ua rau muaj kev phom sij rau tib neeg lub neej kev nyab xeeb.Yog li ntawd, nws yog ib qho tseem ceeb heev rau kev kawm txog cov txheej txheem tsim thiab muaj feem cuam tshuam ntawm cov kab weld thiab nrhiav txoj hauv kev los tshem tawm cov kab weld.
Muaj ob yam yooj yim ntawm cov kab weld hauv kev txhaj tshuaj molded qhov chaw: ib qho yog txias weld kab;Lwm qhov yog kub-melt weld mark.
Influencing yam ntawm weld kab thiab kev ntsuas rau kev txhim kho thiab tshem tawm
1. Kev cuam tshuam ntawm kev txhaj tshuaj molding txheej txheem tsis nyob ntawm cov kab weld
a.Cov nyhuv ntawm qhov kub thiab txias
Ua kom qhov kub thiab txias tuaj yeem ua kom cov txheej txheem so ntawm lub polymer thiab txo lub sij hawm ntawm molecular saw entanglement, uas yog ntau conducive rau tag nrho fusion, diffusion thiab entanglement ntawm cov molecules nyob rau hauv pem hauv ntej kawg ntawm cov khoom, thiaj li mus txhim kho lub zog ntawm qhov weld kab cheeb tsam.Qhov kub yaj muaj qhov loj tshaj qhov cuam tshuam ntawm weld kab zog ntawmABS yas qhov chaw.
b.Cov nyhuv ntawm kev txhaj tshuaj siab thiab tuav lub siab
Kev txhaj tshuaj siab yog qhov tseem ceeb hauv cov yas yaj sau thiab molding.Nws lub luag haujlwm yog kom kov yeej qhov kev tiv thaiv ntawm cov yas yaj ntws hauv lub thoob, lub taub hau, lub qhov rooj thiab cov kab noj hniav, muab cov puv puv nrawm rau cov yas yaj, thiab cog cov yaj kom zoo ntawm cov khoom txhaj tshuaj molded.
c.Cov nyhuv ntawm kev txhaj tshuaj nrawm thiab lub sijhawm txhaj tshuaj
Kev txhaj tshuaj nrawm dua thiab txo lub sijhawm txhaj tshuaj yuav txo qis lub sijhawm ntws ua ntej yaj hauv pem hauv ntej, txo cov cua sov poob, ntxiv dag zog rau shear tshav kub tiam, txo cov yaj viscosity thiab nce fluidity, thiaj li txhim kho lub zog ntawm vuam kab. .
2. Kev cuam tshuam ntawm kev tuag tsim ntawm cov kab weld
a.Tsim qhov rooj qhov system
Qhov ntau ntawm cov rooj vag, ntau qhov sib txuas yuav raug tsim.Yog hais tias cov yaj nyob rau hauv pem hauv ntej ntawm cov khoom ntws los ntawm txhua lub rooj vag tsis tuaj yeem fused zoo, cov cim vuam yuav ua rau hnyav dua thiab qhov zoo ntawm cov khoom yas yuav raug cuam tshuam loj heev.
b.Tsim kom muaj qhov tso pa tawm thiab txias txias kom zoo
Cov roj seem uas tsim los ntawm cov pa tsis zoo yog compressed hauv pwm kab noj hniav thaum lub sij hawm txhaj tshuaj, uas yuav tsis tsuas hlawv cov khoom, tab sis kuj ua rau cov tsos ntawm fusion cim.
c.Tsim kev tswj qhov kub thiab txias
Qhov qis pwm kub, qhov tsis zoo rau tag nrho fusion ntawm yaj.
d.Kev tsim ntawm nto roughness ntawm kab noj hniav thiab core
Qhov saum npoo roughness ntawm kab noj hniav thiab cov tub ntxhais tseem yuav cuam tshuam rau cov dej ntws nrawm ntawm cov yas yaj.
e.Txhim kho cov qauv tuag nyob rau hauv lwm yam
Cov qauv siv hluav taws xob muaj feem xyuam rau cov qauv pwm uas tuaj yeem tshem tawm cov tsos fusion cim ntawm cov khoom ntxeem tau txhaj tshuaj molded.Txoj kev tshwj xeeb yog tias thaum cov khoom tsuas yog txhaj tshuaj thiab ntim rau hauv pwm kab noj hniav, cov khoom muag muag hauv cov pwm kab noj hniav yog txiav los ntawm kev siv cov tub ntxhais ntxig kom tau cov khoom qhov.
3. Kev cuam tshuam ntawm kev sib txuas ntawm lub valve koob lub rooj vag tshuab ntawm cov kab vuam
Nyob rau hauv lub siab automated huab hwm coj ntau lawm txheej txheem ntawm cov khoom, yuav luag tag nrho cov loj txhaj molding qhov chaw txais yuav kub khiav system.Rau cov khoom yas no, ntau lub rooj vag kua nplaum pub tuaj yeem ua kom tiav cov kab noj hniav thiab txhim kho kev ua haujlwm, tab sis nws yuav ua rau cov khoom lag luam ntws tawm, uas ua rau muaj qhov tshwm sim ntawm cov kab txuas.Los ntawm qhib lub rooj vag valve koob nyob rau hauv ib ntus, cov yaj ntws tuaj yeem fused rau ob qho kawg ntawm kab noj hniav nyob rau hauv lem, thiaj li yuav daws tau qhov teeb meem ntawm weld mark.
4. Lwm txoj hauv kev los txhim kho lub zog ntawm vuam kab
a.Ob chav laub pwm filling txoj kev
b.Kev vibration pab txhaj tshuaj molding
