Wararka

Si aad si buuxda uga faa'iidaysato badeecada, waa in qofku marka hore si fiican u fahmayaa, duubabka midabaysana ma aha mid ka reeban. Marka xigta, aan is baro duubabka midabka leh ee dahaarka leh.
Marka hore, waxaan u baahanahay inaan ogaano waxa looxa dahaarka ah midabka?

Xarigga birta midabka leh ee dahaarka leh iyadoo la isticmaalayo xariijin bir ah oo kulul sida substrate-ku maaha oo kaliya inuu leeyahay lakabka zinc ee ilaalinta, laakiin sidoo kale wuxuu leeyahay daahan organic on lakabka zinc si loogu daboolo iyo ilaalinta, ka hortagga birta birta inay daxaloobaan. Nolosheeda adeeg waxay ku saabsan tahay 1.5 jeer ka dheer ta xariijimaha birta galvanized. Marka labaad, waxaan u baahanahay inaan marka hore fahamno ujeedooyinka duubabka midabka leh? Duubabka dahaarka leh ee midabkoodu waa khafiif, qurux ahaan, waxayna leeyihiin iska caabin daxalka oo wanaagsan. Waxa kale oo si toos ah loo farsamayn karaa waxaana guud ahaan lagu heli karaa hadhka cad cawlan, buluug badeed, iyo casaan leben ah. Inta badan waxaa loo isticmaalaa xayaysiiska, dhismaha, qalabka guriga, alaabta guriga, iyo warshadaha gaadiidka.
Dahaarka loo isticmaalo duubabka midabada leh waa in ay doortaan resins ku habboon iyadoo loo eegayo jawiga isticmaalka ee kala duwan, sida polyester silicon modified polyester, polyvinyl chloride sol, chloride polyvinylidene, iwm. Isticmaalayaasha waxay dooran karaan si waafaqsan isticmaalkooda. Marka xigta, waxaad u baahan tahay inaad ogaato qaabka daahan:
V nooca qaab dhismeedka daahan
2/1: Marso laba jeer dusha sare, mar dusha hoose, oo dub laba jeer.
2/1M: Marso laba jeer dusha sare iyo kuwa hoose, oo dub hal mar.
2/2: Marso laba jeer dusha sare iyo kuwa hoose, oo dub laba jeer.
Isticmaalka qaababka kala duwan ee daahan:
2/1: Iska caabbinta daxalka iyo iska caabbinta xoqan ee rinjiga dhabarka ee hal lakab ayaa liidata, laakiin waxay leedahay adhesion wanaagsan waxaana inta badan loo isticmaalaa sanduuqyada sandwich;
2/1M: Rinjiga dhabarku wuxuu leeyahay iska caabin daxaleed oo wanaagsan, iska caabin xoqan, iyo qaabaynta qaabaynta, oo leh dhejis wanaagsan, oo ku habboon muraayadaha hal-lakab ah ee profiled iyo sanduuqyada sandwich.
2/2: Rinjiga dhabarka ee laba-lakabka ah wuxuu leeyahay iska caabin daxaleed oo wanaagsan, iska caabin xoqan, iyo qaabaynta farsamaynta, waxaana inta badan loo isticmaalaa muraayadaha muuqaalka leh ee hal lakab ah. Si kastaba ha ahaatee, ku dhegganaantiisa ayaa liidata oo kuma haboona saanwijka.

Waa maxay kala-soocida substrates-ka midabka leh?
Qulqulka kulul ee substrate galvanized
Alaabada la helay iyadoo lagu dabaqayo daahan organic ah xaashida birta galvanized-kuleelka waa xaashi midab leh oo kulul. Midabka dahaarka leh ee kulul ma leh oo kaliya saamaynta ilaalinta zinc, laakiin daahan organic ee dusha sare ayaa sidoo kale door ka ciyaara ilaalinta dahaarka iyo ka hortagga miridhku, oo leh nolol adeeg ka dheer xaashida galvanized kulul. Macnaha Zinc ee ku jira substrate-ku-kulul-kulul guud ahaan waa 180g/m2 (laba-geesood), iyo maadada zinc sare ee substrate-ka galvanized-ka-kulul ee isticmaalka dibadda ee dhismayaasha waa 275g/m2.
Kuleylka kulul ee aluminiumka zinc substrate
Saxan bir ah oo kulul oo aluminium zinc ah (55% Al Zn) ayaa loo isticmaalaa sidii substrate-ka cusub ee dahaarka leh, badiyaa ka kooban zinc aluminium ah oo ah 150g/㎡ (laba dhinac). Iska caabinta xaashida zinc ee kuleylka leh ee aluminiumku waa 2-5 jeer ka mid ah xaashida galvanized-kuleelka ah. Isticmaalka joogtada ah ama joogtada ah ee heerkulka ilaa 490 ℃ ma keenayso oksaydhyo daran ama samaynta miisaan oksaydh ah. Awoodda lagu muujinayo kulaylka iyo iftiinka ayaa labanlaab ka ah saxan bir ah oo kulul, iyo milicsi ka weyn 0.75 waa qalab dhisme oo ku habboon kaydinta tamarta.
Substrate galvanized koronto
Alaabta lagu helay iyadoo la isticmaalayo xaashi galvanized koronto ah sida substrate-ka oo lagu dubay daahan organic waa xaashi midab leh oo galvanized koronto ah. Sababtoo ah lakabka zinc dhuuban ee xaashida galvanized electroplated, content zinc inta badan waa 20 / 20g / m2, sidaas darteed alaabtani kuma haboona isticmaalka dibadda ee samaynta derbiyada, saqafka, iwm. Laakiin ay sabab u tahay muuqaalka quruxda badan iyo waxqabadka farsamaynta, Inta badan waxaa loo isticmaali karaa qalabka guriga, hababka maqalka, alaabta guriga ee birta ah, qurxinta gudaha, iwm. Markaad tan maqasho, miyaad wax aqoon ah u leedahay duubabka midabada leh? Haddii aad danaynayso, kaalay oo nala tasho!
