Khadka dahaarka budada ayaa arrimaha dahaarka budada MDF ah

Khadka dahaarka budada ah ayaa la xaqiijiyay inuu yahay qodobka ugu muhiimsan ee helitaanka MDF tayo sare leh dahaarka budada. Nasiib darro shirkadaha yaryar ee budada ah ee birta ah, suurtogal maaha in la helo tayada sare ee budada MDF ee khadadka dahaarka budada ah ee duugga ah.

Qaybta ugu muhiimsan ee xariiqda daahan budada ah waa tignoolajiyada foornada oo dhalaalaysa rinjiga. Haddii ay dhacdo kuleyl ku daaweynaysa budada daaweynta kiimikada. Waxyaabaha ay tahay in maskaxda lagu hayo waa dhaqdhaqaaqa kulaylka hooseeya ee MDF. Sidaa darteed, foornooyinka waxay u baahan yihiin in la qaabeeyo si heerkulkooda loo qaybiyo si siman; Haddii kale, kulaylka looma qaybin doono dusha sare ee substrate sida aluminium. Si kastaba ha noqotee, marka lagu kululeeyo MDF, waa in la hubiyaa qaybinta heerkulbeeg isku mid ah

Waxaan tan ka faa'iidaysanay sababtoo ah kulaylka hooseeya ee MDF. Sida hore loo soo sheegay, budada ayaa dhalaali oo ku adkeysata heerkulka ku habboon. Heerkulkani wuu ka badan yahay inta ay MDF xamili karto. Si kastaba ha ahaatee, marka budada lagu kululeeyo fallaadhaha infrared, budada iyo dusha sare ee looxa ayaa si dhakhso ah u gaadha heerkulka dhalaalka iyo adkeynta. Iyada oo ay ugu wacan tahay kulaylka kuleylka hooseeya ee looxa, heerkulka dhexe ee guddiga ayaa weli ah mid hooseeya, aad uga hooseeya heerkulka budada oo dhan lagu dhalaalay oo la adkeeyey. Sidaa darteed, diiqada kulaylka ee guddiga MDF waa la yareeyaa iyada oo aan waxyeello loo geysan

Waxaan arki karnaa in labada foornood ee kor lagu soo bandhigay ay yihiin daaweyn kuleyl ah iyo daawaynta UV, kuwaas oo aan ku habboonayn daaha budada MDF. Daawaynta kulaylka budada ah ee caadiga ah iyo kuleylinta MDF waxay qaadataa waqti dheer si ay u gaaraan 150-160 darajo sababtoo ah kulaylka hooseeya ee MDF. Natiijo ahaan, budada si buuxda looma daweyn oo MDF ayaa waxyeelo gaartay. Daawooyinka kale ee UV, ilaa hadda si loo gaaro qaybinta isku midka ah ee xoogga UV iyo qiyaasta, isla mar ahaantaana heerka daaweynta kala duwan midabo, dhumucda daahan budo kala duwan. Sidaa darteed, daaweynta UV wali si guul leh uma isticmaalin tusaale ahaan daaha budada MDF. Si kastaba ha noqotee, daawaynta UV waxaa loo isticmaalaa daahan budada MDF ee lakabyada indhaha ku salaysan budada hufan (ma faahfaahinin tusaalahan).

Codsiga guusha leh ee dhalaalidda iyo daawaynta daaha budada MDF waa foornada infrared. Caqabadda ayaa ah in la bixiyo soo-gaadhista IR labis ah oogada MDF, oo ay ku jiraan geesaha. Nasiib wanaag, foornooyinka casriga ah ee infrared waxay leeyihiin heer sare oo shucaac isku mid ah. Jaantuska 6 waa khariidad qaybinta heerkulka dusha sare oo lagu cabbiro dareemayaasha heerkulka sare, dhexe iyo hoose ee foornada infrared MDF. Heerkul qaybinta dusha MDF aad ayey u kala duwan tahay, heerkulku waa ka yar yahay 15°F
Foornada daweynta IR si wanaagsan loo qaabeeyey oo muujinaysa heerkulka isbeddelka ka hooseeya 15 ° F kor ilaa hoos ee substrate-ka MDF

Si loo helo daahan budo ah oo wanaagsan, qaybinta heerkulka foornada waa in la cabbiraa ka hor inta aan la bilaabin daahan budada ah. Cabbir oo la soco maaha oo kaliya goobta dusha sare, laakiin sidoo kale agagaarka dusha MDF, oo ay ku jiraan geesaheeda. Heerkulka foornada waa in la hagaajiyaa si looga fogaado kala duwanaanshaha heerkulka u dhexeeya meelaha xad dhaafka ah, sida in ka yar 15°F. Jaantuska 7 waa labada qaybood ee heerkulbeegyada a iyo b. Jaantuska 7a waa qaboojiyaha si fiican foornada infrared; dareemaha ayaa lagu hagaajiyaa meelo kala duwan oo ku yaala dusha MDF, oo ay ku jiraan geesaha. Waxaan arki karnaa in qaybinta heerkulka dusha sare ee MDF uu yahay mid isku mid ah.

Sida cad, foornooyinka MDF ee leh heerkulka dusha sare ee isbeddelaya in ka badan 75 ° F ma gaari doonaan waxqabadka daahan budada isku midka ah. Xaaladaha qaarkood, xitaa qaybinta heerkulka isku midka ah lama gaari karo sababtoo ah cilladaha farsamada ee foornada. Xaaladaha kale, foornooyinka si fiican loo qaabeeyey ayaa lagu dhejiyaa heerkulka saxda ah. Xaaladahani waxay keenayaan xaqiiqda ah in budada budada ah aan loo isticmaalin wax soo saarka iyo xaalado badan oo keena fashilka budada MDF.

Cabbirka substrate-ka ee la bixiyay (ay ku jiraan geesaha), dhalaali - heerkulka ugu badan ee foornada lagu daweynayo, dood wanaagsan, iyo sharciyo adag ka hor intaanad wax go'aan ah la gaarin soo saaraha. Marka foornada la rakibo, dejinta khadka wax-soo-saarka waa in lagu hagaajiyaa iyada oo loo marayo cabbirka astaanta heerkulka iyo kormeerka heerkulka joogtada ah inta lagu jiro wax soo saarka. Tani waxay hubin doontaa in tayada daahan budada ah ay ku jirto qeexid.
