Cov teeb meem thiab kev daws teeb meem hauv cov txheej txheem tsim khoom ntawm PVC ua npuas ncauj ntawv # PVCfoamed sheetextrusion

Cov teeb meem thiab cov kev daws teeb meem hauv cov txheej txheem tsim khoom ntawm PVC ua npuas ncauj ntawv#PVC ua npuas ncauj daim ntawv extrusion

1. Lubricant sib npaug

1. Kev plam sab nraud tsis txaus. Qhov kub hauv thaj tsam 5 ntawm lub tshuab extruder nyuaj rau tswj thiab yooj yim rau cua sov, ua rau qhov kub siab ntawm lub hauv paus sib sau ua ke. Teeb meem xws li cov npuas loj, cov npuas dej, thiab daj hauv nruab nrab ntawm lub rooj tsavxwm. Qhov chaw ntawm lub rooj tsavxwm kuj tsis du. Kev plam sab nraud ntau dhau. Cov dej nag yuav dhau los ua qhov hnyav, uas yuav pom tseeb hauv cov qauv hauv pwm thiab cov dej nag ntawm qhov chaw ntawm lub phaj. Nws kuj tseem yuav tshwm sim ua qee qhov xwm txheej txav mus los tsis sib xws ntawm qhov chaw ntawm lub phaj.
2. Qhov tsis txaus ntawm sab hauv txhais tau tias nws nyuaj rau tswj qhov tuab ntawm lub rooj tsavxwm, uas yog qhov pom tseeb tias lub rooj tsavxwm tuab hauv nruab nrab thiab nyias ntawm ob sab; ntau dhau sab hauv plam yog qhov ua rau kub siab hauv lub hauv paus sib sau ua ke.

2. Pawg thawj coj saib xyuas

1. Qhov chaw ntawm lub rooj tsavxwm tig daj: qhov kub ntawm extrusion siab dhau lossis qhov ruaj khov ntawm lub stabilizer tsis txaus. Kev daws teeb meem yog txo qhov kub ntawm kev ua. Yog tias tsis muaj kev txhim kho, koj tuaj yeem kho cov mis thiab nce qhov ntau ntawm cov stabilizer thiab cov roj nplua nyeem kom haum. Koj tuaj yeem hloov nws ib qho los ntawm ib qho, uas yooj yim. Nrhiav qhov teeb meem sai sai thiab daws nws sai li sai tau.
2. Daj nyob nruab nrab ntawm lub phaj: Qhov laj thawj tseem ceeb yog cuam tshuam nrog qhov kub siab ntawm thaj chaw lub thoob thiab qhov kub ntawm pwm, nrog rau qhov ntau ntawm cov roj nplua nyeem, uas kuj cuam tshuam nrog tus neeg sawv cev ua npuas dawb. Txheej txheem los ntawm kev kho qhov kub ntawm cov txheej txheem lossis kho qhov sib piv ntxiv ntawm cov npuas dawb.
3. Rooj tsavxwm khoov: Qhov laj thawj tseem ceeb yog cov khoom ntws tsis sib xws lossis txias tsis txaus. Cov yam ua rau cov khoom ntws tsis sib xws feem ntau suav nrog kev hloov pauv loj ntawm traction lossis tsis sib xws sab hauv thiab sab nraud lubrication hauv cov mis. Cov yam ntxwv ntawm lub tshuab yooj yim tshem tawm. Kev hloov kho mis feem ntau xav tau lubrication sab nraud ntau li ntau tau. Kev kho cov roj nplua nyeem sab hauv qab lub hauv paus ntawm cov roj tsawg dua yuav muaj txiaj ntsig zoo thiab ua kom txias sib xws. Thaum lub sijhawm tsim khoom, qhov kub ntawm dej hauv lub pwm feem ntau tswj tau ntawm 30-40 ° C, thiab qhov kub ntawm dej hauv lub rooj teeb tsa feem ntau tswj tau ntawm 15-20 ° C, uas yog qhov ntau zoo tshaj plaws.
4. Lub rooj tsavxwm tuab tsis sib npaug: Cov khoom tawm tsis sib npaug. Koj tuaj yeem kho qhov siab ntawm daim di ncauj tuag. Yog tias qhov ntws nrawm dhau, koj tuaj yeem kho tus pas nrig thaiv ntws thiab cov mis. Feem ntau, yog tias muaj ntau lubrication sab hauv, nruab nrab yuav tuab dua, thiab yog tias muaj ntau lubrication sab nraud, cov khoom yuav ntws sai dua ntawm ob sab.
5. Kev hloov pauv ntawm cov phaj tuab, cov qauv, thiab lwm yam uas yuav tshwm sim thaum lub sijhawm hloov pauv: Qhov laj thawj tseem ceeb yog tias cov khoom siv raw sib xyaw hloov pauv. Tom qab sib tov hauv qhov hloov pauv dhau los, yuav muaj lub sijhawm ntev ntawm kev sib tov tom qab qhov hloov pauv tom ntej, thiab lub lauj kaub sib tov kub yuav txias zoo. , thawj lub lauj kaub ntawm kev sib tov yog pre-plasticized zoo, uas txawv ntawm qhov sib tov dhau los. Thaum lwm yam mob tseem tsis tau hloov pauv, nws yooj yim ua rau muaj kev hloov pauv. Qhov no tuaj yeem daws tau los ntawm kev kho qhov traction thiab kev ua haujlwm kub lossis los ntawm kev ua kom cov khoom sib tov sib xyaw.

3. Cov hlwb ua npuas dej hla ntu

1. Cov laj thawj rau qhov tshwm sim ntawm cov hlwb lossis cov npuas dej hauv seem hla tuaj yeem yog vim ib qho, uas yog lub zog yaj tsis txaus. Cov laj thawj rau lub zog yaj tsis txaus yog: thawj, tus neeg sawv cev ua npuas ntau dhau lossis tus tswj kev ua npuas tsis txaus lossis qhov sib piv tsis sib xws ntawm ob qho. , lossis cov teeb meem zoo ntawm tus tswj kev ua npuas. Qhov thib ob yog kev ua kom yas tsis zoo, qhov kub ua haujlwm qis lossis lubrication ntau dhau.
2. Muaj ob yam ua rau muaj kev ua npuas lossis ua npuas hauv seem ntawm daim ntawv yas ua npuas: ib qho yog tias lub zog hauv zos ntawm cov yaj nws tus kheej qis dhau, thiab kev ua npuas yog tsim los ntawm sab nraud mus rau hauv; qhov thib ob yog tias lub siab nyob ib puag ncig cov yaj me dhau, thiab kev ua npuas tshwm sim hauv zos. Cov cell nthuav dav, lawv lub zog tsis muaj zog, thiab cov cell tawg yog tsim los ntawm sab hauv mus rau sab nraud. Hauv kev xyaum tsim khoom, tsis muaj qhov sib txawv pom tseeb ntawm ob qho teebmeem, thiab lawv tuaj yeem nyob ua ke tib lub sijhawm. Feem ntau ntawm cov qhov tawg yog tshwm sim los ntawm kev txo qis ntawm lub zog yaj tom qab kev nthuav dav tsis sib xws ntawm cov cell hauv zos.
