Waa maxayBiley xaashi ah oo bir ah?
Sanadkii 1902, injineer Jarmal ah oo la yiraahdo Larsen ayaa marka hore soo saaray nooc ka mid ah xaashida xaashida bilihiisa oo qaab u dhexeeya qaabka u eg iyo qufulka labada dhinacba, kaas oo si guul leh loogu dabaqay injineernimada, oo loo yaqaan "Larsen xaashida xaashidaMagiciisu ka dib. Maalmadii, Larsen Steles Steles oo dhan ayaa loo adeegsaday oo si ballaaran loogu adeegsaday Taageerada Aasaaska, Childring Coffrafkams, ilaalinta daadadka iyo mashaariicda kale.
The lensen bir bir ah waa heer caalami ah oo caalami ah, oo ah nooca xaashida xaashida ee Lassen bilidka ee la soo saaray dalal kala duwan ayaa lagu qasi karaa isla mashruuca. Heerka wax soo saarka ee xaashida xaashida birta ee Larnen Steel ayaa ka dhigay qodobo cad iyo shuruudo ku saabsan cabirka qaybta, qaabka qufulka, astaamaha farsamada, iyo heerarka kormeerka ee maaddada, iyo badeecadaha lagu soo bandhigo warshadda. Sidaa darteed, xaashida xaashida bilihii ee LarSen Steel waxay leedahay hubinta tayada wanaagsan iyo guryaha farsamada, waxaana si isdaba joog ah loogu isticmaali karaa sida wax lagu wareejiyo, kaas oo leh faa iidooyin aan la beddeli karin oo lagu hubinayo tayada dhismaha iyo yareynta qiimaha mashruuca.
Noocyada LarSen Stel xaashida birta
Sida laga soo xigtay ballac qaybo kala duwan, dherer iyo dhumuc, dhumucyo bir ah ayaa loo qaybin karaa tusaalayaal kala duwan, iyo ballaca wax ku oolka ah ee hal xaashida xaashida ugu badan ee loo yaqaan 'pures' inta badan waxay leeyihiin seddex sharradood, oo ah 400mm, 500mm iyo 600mm.
Dhererka xaashida xaashida Tensental ee Tensentada waa la dhisan karaa oo la soo saari karaa iyadoo loo eegayo baahida loo qabo mashruuca, ama loo gooyn karo gogosha gaagaaban ama lagu gilgi karo godad dheer ka dib iibsashada. Markii aysan suurtagal ahayn in la qaado xaashida xaashida dhaadheer ee saldhiga sare ee goobta dhismaha sababtuna tahay xaddidaadda baabuurta iyo wadooyinka, waxaa loo qaadi karaa isla goobta dhismaha ka dibna waa la dheereeyaa oo la dheereeyaa.
Shayga xaashiyaha bilihii ee LarSen
Marka loo eego awooda dhalidda ee maaddada, shahaadada shayga ee xaashida xaashida birta ee Larnen Stels waa Q255P, Q390p, Q455p, iyo kuwa u dhigaya heerka Jabaan.SY295, SY390, iwm. Fasalada kala duwan ee agabyada, marka lagu daro waxyaalaha kiimikaadkooda, sidoo kale waa la shaaciyaa oo la dheereyn karaa. Darajooyinka kala duwan ee agabyada marka lagu daro halabuurka kiimikaad ee kala duwan, cabiraada farsamada ayaa sidoo kale ka duwan.
