Extruded profiles yog dav siv cov khoom yas tsim los ntawm kev nruam extrusion. Piv nrog rau kev txhaj tshuaj ib txwm siv- cov khoom siv molded, extruded profiles yog tus cwj pwm los ntawm qhov ntev txuas ntxiv, hloov tau yooj yim hla- cov qauv tsim thiab tsim tau zoo. Lawv feem ntau siv hauv kev tsim kho, tsheb, rooj tog zaum, hluav taws xob thiab khoom siv hauv tsev. Kev tswj xyuas qhov ntev thiab kev ua tau zoo yuav tsum tau ua tib zoo tswj cov khoom siv, qhov kub thiab txias, siab, txias thiab thauj khoom- tawm thoob plaws hauv kev tsim khoom.
Raw khoom npaj yog lub hauv paus ntawm profile extrusion. Cov neeg tsim khoom xaiv cov ntaub ntawv thermoplastic haum raws li daim ntawv thov thiab npaj cov khoom siv ntxiv raws li cov khoom xav tau. Qee cov dej noo- cov ntaub ntawv rhiab heev yuav xav tau kom qhuav ua ntej ua kom txo qis qhov cuam tshuam ntawm ya raws ntawm extrusion stability thiab nto zoo.
Cov ntaub ntawv npaj tau txav mus los ntawm batching thiab blending theem. Cov khoom xyaw sib txawv yog sib xyaw ua ke raws li kev tswj xyuas kom ua tiav cov khoom sib xws. Nyob ntawm cov khoom xav tau, cov tshuaj pleev xim, stabilizers thiab lwm yam khoom siv ntxiv kuj tuaj yeem koom ua ke. Kev npaj cov ntaub ntawv zoo ib yam pab tswj kev ua haujlwm ruaj khov thaum lub sij hawm extrusion.
Extrusion yog qhov tseem ceeb ntawm cov txheej txheem tsim khoom. Cov khoom sib tov nkag mus rau hauv extruder, qhov twg nws yog rhuab thiab plasticized ua ntej raug xa mus los ntawm cov ntsia hlau. Cov khoom siv molten raug yuam los ntawm kev tsim tshwj xeeb extrusion tuag, uas txiav txim siab tus ntoo khaub lig-sectional geometry ntawm qhov tiav profile. Tuag tsim thiab precision yog li qhov tseem ceeb thaum tsim cov profiles nrog qhov ntev lossis cov duab nyuaj.
Tom qab tawm hauv qhov tuag, qhov tshiab tsim profile undergoes txias thiab calibration. Cov dej txias, cua txias lossis lwm txoj kev tsim nyog tuaj yeem siv los txo cov khoom kub thiab ruaj khov nws cov duab. Kev tswj kom zoo ntawm cov cua txias yog qhov tseem ceeb vim tias qhov tsis sib xws lossis tsis txaus cua txias tuaj yeem ua rau deformation lossis qhov txawv txav.
Cov profile ruaj khov ces txav mus los ntawm kev thauj mus los -tawm thiab txiav cov theem. Kev tswj hwm kev thauj mus los-tawm lub kaw lus rub cov profile rau pem hauv ntej ntawm qhov nrawm nrawm, pab tswj qhov ntev sib xws raws nws qhov ntev. Raws li cov neeg siv khoom thiab cov khoom xav tau, cov ntaub ntawv txuas ntxiv tuaj yeem raug txiav rau hauv qhov ntev thiab tuaj yeem ua haujlwm ntxiv xws li drilling, xuas nrig ntaus lossis nto tiav.
Kev tshuaj xyuas zoo yog ib feem tseem ceeb ntawm cov txheej txheem tsim khoom. Kev tshuaj xyuas yuav suav nrog cov tsos, qhov ntev, tuab, dav, hla -sectional dimensions thiab cov khoom muaj feem xyuam. Hauv - kev saib xyuas thiab ua tiav- cov khoom lag luam tuaj yeem pab txheeb xyuas qhov hloov pauv lossis qhov tsis xws luag thiab txhawb kev hloov kho raws sijhawm.
Zuag qhia tag nrho, extruded profile manufacturing yog ib qho kev sib koom ua ke nrog cov khoom tsim, plasticization, tuag forming, txias, calibration thiab tswj kom zoo. Los ntawm kev tswj xyuas cov kev ua haujlwm ruaj khov thoob plaws txhua theem, cov tuam txhab tsim khoom tuaj yeem txhim kho qhov sib xws thiab kev ntseeg tau ntawm cov khoom lag luam thaum tsim cov yas profiles haum rau ntau yam kev siv.
