Usha Polish-ka ah

Sharaxaad Gaaban:

Usha Polish-ka ah waa nooc ka mid ah usha nuugista gaarka ah oo ku xiran usha nuugista iyo qalabka lagu xidho alwaaxa. Waxay ku taal xagga sare ee usha nuugista, waxay u baahan tahay inay xakamayso xoogga ugu badan, sidaas darteed dhexroorkeedu waa ka weyn yahay oo bir ka sarreeya usha nuugista, dusha sarena aad ayuu u siman yahay.

Qeexitaanka Badeecada

1. Usha Polish-ka waa nooc ka mid ah usha nuugista gaarka ah oo ku xiran usha nuugista iyo qalabka lagu xidho alwaaxa. Waxay ku taal xagga sare ee usha nuugista, waxay u baahan tahay inay xakamayso xoogga ugu badan, sidaas darteed dhexroorkeedu waa ka weyn yahay oo bir ka sarreeya usha nuugista, dusha sarena aad ayuu u siman yahay.

2. Shaqada ugu muhiimsan:

Waxaa lagu daray baakadaha sanduuqa baakadaha si loo xiro madaxa ceelka loona hortago shaacinta saliidda, gaaska, iyo biyaha.

Xidhiidhiye ku meel gaar ah oo u dhexeeya usha nuugista iyo hangar-madaxa baqalka

Tijaabada jaantuska tilmaamaha dhammaystirka.

Dhammaystir hawlgallo kala duwan oo madax ceel ah, sida garaacista bamka, nidaaminta dejinta bamka.

Fiiro gaar ah: Marka xoogga wax soo saarka ugu yar aan la cabbiri karin, waa in loo tixgeliyaa in loo farsameeyo muunad caadi ah oo lagu rakibo extensometer si loo cabbiro.
A Guud ahaan waxaa laga sameeyaa bir kaarboon tayo sare leh, taas oo gaari karta sifooyinka farsamada ee miiska b Bir molybdenum ah (laakiin aan ku xaddidnayn nooca birta ah) ayaa guud ahaan la isticmaalaa, daaweynta kulaylka ee wax ku oolka ahna waxay gaari kartaa sifooyinka farsamada ee jadwalkan
