Kaliya waxaad u baahan tahay inaad kor u qaaddo hal lakab, waxay la kulmi kartaa caabbinta daxalka ee cajaladda alxanka

Tower waxaa loo isticmaalaa distillation, sifaynta, nuugista, distillation iyo qalab kale oo kiimiko ah, inta badan qalabka munaaradaha u baahan yihiin in ay la xiriiraan acid, alkali, cusbo, dareere organic iyo warbaahinta kale ee daxalka, sidaas darteed waxaa lagama maarmaan ah in dusha sare ee aag weyn oo lakabka u adkaysta daxalka. ee dhululubada iyo qaybaha shaabadeynta. Sida hab wax ku ool ah oo dusha sare loo maro, dusha sare ee xariijimaha ayaa si weyn loogu isticmaalaa alxanka munaaradda ee qalabka kiimikada.
Tignoolajiyada sare ee korantada dhaqameedku waa tignoolajiyada korka sare ee lakabka hoose ee laba-lakab leh oo leh lakabka kala guurka iyo lakabka daxalka u adkaysta, laakiin tignoolajiyadani waxay leedahay wareeg wax soo saar dheer iyo kharash wax soo saar oo sarreeya. Si loo xalliyo dhibaatadan, JingQunCo waxay samaysay qalab alxan ah oo hal lakab ah (GDS-309LA welding strip, GXS-ED308L electroslag flux), kaas oo gaari kara saamaynta laba lakab oo dusha sare ah oo leh dusha sare ee hal lakab, oo fududayn kara habka dusha sare ee dusha sare ee laba-lakab ilaa dusha sare ee hal lakab.

2.Muuqaalka alxanka

Qiyaasaha alxanka ee lagu taliyay

Tilmaamaha (mm)	0.5*60
Korontada (A)	850-950
Voltage(V)	26-30
WXawaaraha elding (mm/min)	150
Ldherer (mm)	35-40
Alxanka dhabta ah (mm/min)	6-10
Dhumucda fidinta qulqulka (mm/min)	A25

Dhumucdiisuna waxay ka gudubtaa alxan: qiyaastii 4.7mm

Ballaca alxanka: qiyaastii 62.5mm

Muuqaalka baska alxanka: qaabka quruxda badan, dusha alxanka waa siman yahay, kala-guurka dhabta waa siman yahay.
