Dhismaha dhismaha ama dib-u-habaynta baaxadda weyn, waxaa la isticmaali karaa guddiyo midab leh, haddaba waa maxay guddi midab leh? Sababta ugu weyn ee guddiyada midabka leh loogu isticmaalo nolosheenna waa in guddiyada midabka leh ay leeyihiin iska caabin wanaagsan oo daxal ah, si fudud loo farsamayn karo loona hagaajin karo, waana ka fudud yihiin agabka kale. Sidaa darteed, guddiyada midabka leh ayaa loo isticmaali doonaa dhismaha. Haddaba maxaad ka taqaanaa kala-soocidda looxyada midabka leh? Kuwa soo socda ayaa ku soo bandhigi doona:
1. Saxan bir ah oo midab leh oo loogu talagalay substrate-ka qabow-la duubay
Saxanka midabka leh ee uu soo saaro substrate-ka qabow-rogmada leh wuxuu leeyahay muuqaal siman oo qurux badan, wuxuuna leeyahay waxqabadka habaynta ee saxan qabow-rogmada leh; laakiin xoqitaan kasta oo yar oo ku yaal dahaarka dusha sare wuxuu hawada u soo bandhigi doonaa substrate-ka qabow-rogmada leh, si birta si dhakhso ah loogu soo bandhigo miridhku cas ayaa sameysma. Sidaa darteed, alaabadan waxaa loo isticmaali karaa oo keliya cabbirrada go'doominta ku meel gaarka ah iyo agabka gudaha ee aan u baahnayn.
2. Xaashi bir ah oo lagu dahaadhay midab galvanized oo kulul oo lagu dhex qasay
Badeecada laga helo dahaarka rinjiga dabiiciga ah ee ku yaal xaashida birta lagu dahaadhay ee kulul-maquufinta waa xaashida midabka lagu dahaadhay ee kulul-maquufinta. Marka laga soo tago saameynta ilaalinta ee zinc, xaashida midabka lagu dahaadhay ee kulul-maquufinta ayaa sidoo kale leh dahaar dabiici ah oo dusha sare ah si loo dahaadho loona ilaaliyo loona ilaaliyo miridhku, cimrigeeduna waa ka dheer yahay xaashida galvanized ee kulul-maquufinta. Tirada zinc ee substrate-ka galvanized ee kulul-maquufinta guud ahaan waa 180g/m2 (laba-dhinac), iyo tirada ugu badan ee zinc ee substrate-ka galvanized ee kulul-maquufinta ee dibadda dhismaha waa 275g/m2.
3. Xaashi midab leh oo aluminium-zinc ah oo kulul lagu dahaadhay
Sida waafaqsan shuruudaha, xaashiyaha birta ah ee aluminium-zinc-ku-maroojisan ayaa sidoo kale loo isticmaali karaa substrate midab leh (55% AI-Zn iyo 5% AI-Zn). ...
4. Xaashi midab leh oo koronto-galvanized ah
Xaashida elektaroonigga ah ee la galiyey waxaa loo isticmaalaa sidii substrate, badeecada laga helo dahaarka rinjiga dabiiciga ah iyo dubista waa xaashi midab leh oo elektaroonik ah. Maadaama lakabka zinc ee xaashida elektaroonik ah uu khafiif yahay, maaddada zinc badanaa waa 20/20g/m2, sidaa darteed badeecadani kuma habboona in la isticmaalo. Samee derbiyada, saqafyada, iwm. bannaanka. Laakiin sababtoo ah muuqaalkeeda quruxda badan iyo waxqabadka farsamaynta ee aadka u wanaagsan, waxaa inta badan loo isticmaali karaa qalabka guriga, maqalka, alaabta guriga ee birta ah, qurxinta gudaha, iwm.
