Hmoov txheej kab teeb meem MDF hmoov txheej
Hmoov txheej kab tau ua pov thawj tias yog qhov tseem ceeb tshaj plaws hauv kev tau txais MDF zoo hmoov txheej. Hmoov tsis zoo rau cov tuam txhab me me hlau nto hmoov txheej, nws tsis tuaj yeem tau txais cov khoom zoo MDF hmoov txheej hauv cov hlau qub hmoov txheej kab.
Qhov tseem ceeb tshaj plaws ntawm cov hmoov txheej kab yog qhov cub technology qhov cub xim melting. Nyob rau hauv rooj plaub ntawm thermal curing hmoov chemical curing. Qhov uas yuav tsum nco ntsoov yog qhov tsawg thermal conductivity ntawm MDF. Yog li ntawd, lub qhov cub yuav tsum tau tsim kom lawv qhov kub thiab txias tuaj yeem faib tau sib npaug; txwv tsis pub, cov cua sov yuav tsis raug faib thoob plaws lub substrate nto zoo li txhuas. Txawm li cas los xij, thaum cua sov ntawm MDF, qhov sib txawv ntawm qhov kub thiab txias yuav tsum tau ua kom ntseeg tau
Peb tsuas yog coj kom zoo dua ntawm qhov no vim qhov qis thermal conductivity ntawm MDF. Raws li tau hais ua ntej, cov hmoov melts thiab solidifies ntawm qhov tsim nyog kub. Qhov ntsuas kub no ntau dua li MDF tuaj yeem ua tau. Txawm li cas los xij, thaum cov hmoov yog rhuab los ntawm infrared rays, cov hmoov thiab cov board nto sai ncav cuag qhov kub ntawm melting thiab solidification. Vim lub thermal conductivity qeeb ntawm lub rooj tsavxwm, qhov nruab nrab kub ntawm lub rooj tsavxwm tseem tsis tshua muaj, qis dua qhov kub ntawm qhov uas tag nrho cov hmoov yog melted thiab solidified. Yog li ntawd, thermal stress nyob rau hauv lub MDF board yog minimized yam tsis muaj kev puas tsuaj
Peb tuaj yeem pom tias ob lub qhov cub tau qhia saum toj no yog thermal curing thiab UV curing melt curing, uas tsis haum rau MDF hmoov txheej. Cov pa hluav taws xob tag nrho cov hmoov thermal curing thiab MDF cua sov yuav siv sij hawm ntev kom ncav cuag 150-160 degrees vim qhov tsis tshua muaj thermal conductivity ntawm MDF. Yog li ntawd, cov hmoov tsis tau kho tag nrho thiab MDF tau puas lawm. Lwm qhov kev kho UV, kom deb li deb thiaj li ua tiav qhov kev faib tawm ntawm UV siv thiab koob tshuaj, tib lub sijhawm ntawm kev kho ntawm qhov sib txawv. xim, sib txawv hmoov txheej thickness. Yog li ntawd, UV curing tseem tsis tau ntse siv cov piv txwv ntawm MDF hmoov txheej. Txawm li cas los xij, UV curing yog siv rau MDF hmoov txheej ntawm cov hmoov pob tshab raws li cov txheej txheem kho qhov muag (tsis tau piav qhia hauv qhov piv txwv no).
Ib daim ntawv thov ua tiav rau melting thiab kho ntawm MDF hmoov txheej yog qhov cub infrared. Qhov kev sib tw yog muab cov IR sib xws rau MDF nto, nrog rau cov npoo. Hmoov zoo, niaj hnub infrared qhov cub muaj qhov siab ntawm cov hluav taws xob tsis zoo. Daim duab 6 yog daim ntawv qhia qhov ntsuas kub ntawm qhov chaw ntsuas los ntawm sab sauv, nruab nrab thiab qis kub sensors ntawm lub qhov cub infrared MDF. Qhov kub ntawm qhov chaw ntawm MDF sib txawv me ntsis, thiab qhov kub thiab txias yog tsawg dua 15 ° F
Ib qho zoo tsim IR curing qhov cub qhia qhov kub thiab txias hloov qis dua 15 ° F los ntawm sab saum toj mus rau hauv qab ntawm MDF substrate
Yuav kom tau txais cov hmoov txheej zoo, qhov ntsuas kub ntawm qhov cub yuav tsum tau ntsuas ua ntej pib cov hmoov txheej. Ntsuas thiab saib xyuas tsis yog ntawm qhov chaw saum npoo, tab sis kuj nyob ib puag ncig MDF nto, nrog rau nws cov npoo. Qhov cub kub yuav tsum tau kho kom tsis txhob muaj qhov sib txawv ntawm qhov kub ntawm qhov chaw siab tshaj qhov txwv, xws li tsawg dua 15 ° F. Daim duab 7 yog ob qhov kev faib tawm kub hauv vaj huam sib luag a thiab b. Daim duab 7a yog lub qhov cub txias infrared; lub sensor yog tsau ntawm ntau qhov chaw ntawm MDF nto, nrog rau cov npoo. Peb tuaj yeem pom tias qhov kub thiab txias ntawm MDF nto yog sib xws.
Pom tseeb, MDF qhov cub nrog qhov kub thiab txias ntawm qhov chaw hloov pauv ntau dua 75 ° F yuav tsis ua tiav cov hmoov txheej txheej. Qee qhov xwm txheej, txawm tias qhov ntsuas kub tsis sib xws tsis tuaj yeem ua tiav vim qhov kev ua haujlwm tsis zoo hauv qhov cub. Hauv lwm qhov xwm txheej, qhov cub tsim tau zoo yog teem rau ntawm qhov kub thiab txias. Cov xwm txheej no ua rau lub fact tias cov hmoov txheej yuav tsum tsis txhob siv nyob rau hauv ntau lawm thiab nyob rau hauv ntau rooj plaub ua rau tsis ua hauj lwm ntawm MDF hmoov txheej.
Ntawm qhov muab cov substrate loj (suav nrog cov npoo), yaj - qhov kub siab tshaj plaws ntawm qhov cub curing, kev sib tham zoo, thiab cov kev cai nruj ua ntej txiav txim siab nrog cov chaw tsim khoom. Thaum lub qhov cub tau teeb tsa, kev teeb tsa ntawm cov kab ntau lawm yuav tsum tau ua kom zoo dua los ntawm kev ntsuas qhov ntsuas kub thiab ntsuas qhov ntsuas kub tsis tu ncua thaum lub sijhawm tsim khoom. Qhov no yuav xyuas kom meej tias qhov zoo ntawm cov hmoov txheej yog nyob rau hauv specification.
