Shiinuhu waxa uu soo dhoofsadaa birta shaandhaysa tayada sare leh
Shiinuhu waxa uu soo dejiyaa shaandhaynta hawada tayada sare leh ee dhamaadka koofiyadaha
Daboolka shaandhada ayaa inta badan u adeega inuu xidho labada daraf ee walaxda shaandhada oo uu taageero shayga shaandhada.Waxay ku shaabadaysay qaabab kala duwan markii loo baahdo xaashida birta ah.Dabka dhamaadka waxa guud ahaan lagu shaabadeeyey jeexdin kaas oo wejiga ugu dambeeya ee walxaha shaandhada lagu dhejin karo oo dhejis lagu dhejin karo, dhinaca kalena wuxuu ku xiran yahay shaabad caag ah si uu u shaqeeyo si uu u daboolo walxaha shaandhada oo loo xiro marinka element filter.

2.Qalabka loo isticmaalo in lagu soo saaro koofiyadaha dhamaadka shaandhada waxaa ka mid ah birta galvanized, birta faraha ka-hortagga, birta aan lahayn, iyo walxo kale oo badan.Koofiyadaha dhamaadka shaandhada waxay leeyihiin qaabab kala duwan sida baahiyo kala duwan.Mid kasta oo ka mid ah saddexda qalab ayaa leh faa'iidooyin u gaar ah.
Bir galvanized waxaa lagu dahaadhay zinc oxide si looga hortago miridhku maadaama iskudarka kiimikaadku ay ku qaadato daxalka in ka badan birta.Waxa kale oo ay bedeshaa muuqaalka birta, taasoo siinaysa muuqaal qallafsan.Galvanization waxay ka dhigtaa birta mid xoog badan oo adag in la xoqdo.
Birta faraha ka-hortagga waa nooc ka mid ah saxan daahan isku dhafan ka dib daawaynta u adkaysata faraha ee dusha sare ee birta galvanized.Sababtoo ah tignoolajiyada gaarka ah, dusha sare waa siman yahay oo waa mid aan sun ahayn oo deegaan ahaan u wanaagsan.
Bir daxal laheyn waa maaddo ka hortagta daxalka hawada, uumiga, biyaha iyo aashitada, alkali, milixda, iyo warbaahinta kale ee kiimikada ah.Noocyada caadiga ah ee birta aan lahayn waxaa ka mid ah 201, 304, 316, 316L, iwm.
3. Tilmaamaha,Waxaa jira cabbirro qaybo tixraac ah, ma aha dhammaan.Ku soo dhawoow inaad nala soo xiriirto si aan u wada hadalno.
