Warshadaha sunta rasaasta-ashitada ee dalkaygu waxay leeyihiin taariikh in ka badan boqol sano. Sababo la xiriira sifooyinka agabka raqiis ah, tignoolajiyada fudud, tignoolajiyada qaan-gaadhka ah, is-dejinta hoose, iyo shuruudaha dayactirka la'aanta, waxay wali xukumi doontaa suuqa dhowrka sano ee soo socda.
Iyada oo la kordhinayo shuruudaha tayada ee birta shubka ah, isticmaalka aluminium ee deoxidation ee qaar ka mid ah shubista heerka sare ma buuxin karto shuruudaha. Sidaa darteed, isticmaalka aluminium iyo kalsiyum isku-darka deoxidation ayaa helay fiiro gaar ah.
Astaamaha ugu muhiimsan ee Zinc Alloy:
1. Qayb weyn.
2. Waxqabadka shubista wanaagsan, waxay u dhiman kartaa qaybo sax ah oo leh qaabab adag iyo darbiyo dhuuban, oo leh meelo shub ah oo siman.
Rinjiga calaamadeynta wadada waxaa sidoo kale loo yaqaan midabka calaamadaynta wadada, Sidoo kale loo yaqaan rinjiga ka-hortagga barafka. Kala saariddeeda faahfaahsan waa sida soo socota:
Xabagta gaarka ah ee rinjiga dhalaalaysa ee kulul ee wadada dhalaalaysa waa M2000A oo ay samaysay shirkadeena sanado badan oo cilmi baaris ah kadib. Waxay ka samaysan tahay rosin, polymer molecular sare, dibasic acid unsaturated, iyo polyol ka dib polycondensation iyo esterification, ku daraysa kulaylka, iftiin La sameeyey ka dib xasiliyaha. Marka la barbar dhigo rosin dhaqameedka wax laga beddelay ee calaamadaynta rinjiga,
Rinjiga calaamadaynta wadada waa rinji lagu mariyo wadada si loo calaamadiyo calaamadaha wadada. Waa calaamad badbaado iyo "luuqad" oo ku dhex jirta taraafikada waddooyinka. Haddaba waa maxay dhibaatooyinka caadiga ah ee dhismaha rinjiga kululaynta waddada dhalaalaysa? Maxaa xal ah?
