Nuska 2H waa qalab tayo sare leh oo culeys badan leh oo si weyn loogu isticmaalo codsiyada farsamada iyo warshadaha.Laga sameeyay birta kaarboonka ee been abuurka ah, lawska waxaa loogu talagalay in uu u adkeysto culeysyada sare iyo bixinta waxqabad joogto ah xitaa meelaha ugu daran.
Iyada oo leh heerkeeda adag ee 2H ee gaarka ah, lowskani wuxuu bixiyaa xoog aan la barbar dhigi karin iyo adkeysi ka badan heerka DIN iyo tilmaamaha ISO.Tani waxay ka dhigaysaa doorasho ku habboon codsiyada hawl-culus halkaas oo badbaadada iyo isku halaynta ay muhiim u yihiin, sida dhismaha, macdanta, iyo warshadaha saliidda iyo gaasta.
Nuska 2H waxa uu leeyahay qaab laba geesood ah kaas oo sahlaya in lagu rakibo iyada oo la isticmaalayo furaha ama godka caadiga ah.La jaanqaadkeeda boolal iyo boolal-xidhka caadiga ah waxay sidoo kale ka dhigaysaa xal la taaban karo oo loogu talagalay codsiyo kala duwan.
Marka lagu daro xooggiisa gaarka ah iyo adkeysiga, lowska 2H wuxuu sidoo kale u adkaystaa daxalka iyo miridhku.Tani waxay ka dhigaysaa mid ku habboon in lagu isticmaalo degaannada qallafsan halkaas oo soo-gaadhista qoyaanka iyo kiimikooyinka ay ku badan yihiin.
Lagu soo saaray heerarka tayada ugu sarreeya, lowska 2H wuxuu maraa baaritaan adag iyo kormeer si loo hubiyo inay buuxisay ama dhaaftay shuruudaha warshadaha.Iyada oo leh waxqabadkeeda la isku halleyn karo, nolosha adeegga dheer, iyo rakibidda fudud, 2H lowska waa qayb muhiim ah oo ka mid ah codsi kasta oo culus oo warshadeed.
Haddii aad u baahan tahay inaad ku xidho qalabka culus, mishiinada, ama dhismayaasha, lowska 2H waa xalka ugu fiican ee bixiya xoog, adkeysi, iyo badbaado aan la qiyaasi karin.
