Dhalada si weyn ayaa loo isticmaalaa nolol maalmeedkeena.Waxa jira noocyo badan oo galaas ah, sidamuraayad aad u khafiif ah, galaaska aadka u dhuuban waxa loola jeedaa galaaska saxan ee dhumucdiisu ka hooseyso 2.0mm.Marka la barbardhigo muraayadda caadiga ah, shuruudaha habka wax soo saarka ee muraayadda khafiifka ah ayaa aad u sarreeya, sidaas darteed wax soo saarku aad ayuu u adag yahay.Aan wax ka baranno.
Muraayadaha khafiifka ah ee aadka u khafiifka ah iyo maalin kasta waxay badanaa arkaan dhalada, waa walxo adag oo metastable amorphous leh oo leh qaab aan caadi ahayn, isotropy, ma jirto meel dhalaalaysa, asymptotic iyo dib loo rogi karo, guud ahaan leh noocyo kala duwan oo macdano ah (sida quartz ciid, borax, boric acid, iwm.) sida alaabta ceeriin ee ugu muhiimsan, marka lagu daro qadar yar oo ah alaabta ceeriin ee caawimada ah oo la sameeyay.Qaybaheeda ugu muhiimsan waa silica iyo oksaydhyada kale, waa cusbada silicate double.Farqiga u dhexeeya dhalooyinka aadka u dhuuban iyo galaaska caadiga ah waa farqiga u dhexeeya dhumucda.Waxaa guud ahaan la rumeysan yahay in dhumucda dhaladu ay ka yar tahay 3.0mm.
Faa'iidooyinka muraayadda aadka u dhuuban:
1, marka loo eego galaaska caadiga ah, galaaska aadka u khafiifka ah ayaa ka hufan, ka nadiifsan, dhalaalaya oo qurux badan in la isticmaalo
2, sababtoo ah muraayadda khafiifka ah, si ka sii fiican waxqabadka gudbinta iftiinka, si fiican u dabacsanaanta, miisaanku waa la dhimi doonaa, taas oo ah faa'iidada ugu muhiimsan ee muraayadda khafiifka ah.
3, oogada muraayadda aadka u khafiifka ah ayaa aad u fidsan, waxaa jira wax badan oo ka mid ah muraayadaha sawirka, muraayadda, muraayadda qurxinta sare, iftiinka iyo wixii la mid ah ayaa sidoo kale isticmaalaya alaabta muraayadaha khafiifka ah.
4, galaaska aadka u khafiifka ah ayaa aad u xasaasi ah, waxaa loo isticmaali karaa shaashadda gacanta oogada, kombiyuutarada kiniiniga, alaabta elektarooniga ah iyo noocyo kala duwan oo qalab sax ah, hawlgalku waa mid degdeg ah oo ku habboon, dabacsanaan badan.
Codsiga:
Muraayada aadka u khafiifka ah waa mid ka mid ah alaabta ceeriin ee ugu muhiimsan ee farsamaynta qoto dheer.Inta badan waxaa loo isticmaalaa dusha gacanta, oogada qalabka caafimaadka, muraayadda la isku qurxiyo, nalka, loo isticmaalo sacadda oogada, muraayadda sawirka, samaynta muraayadda, iwm.
