Qeexida xaashida birta ee la dubay ee kulul
Xaashida kulul ee duuban ee birta ah ee leh hannaankii kor loo qaaday ee korka. Habka kor loo qaaday waxa loo qaabayn karaa sida rombus, digir ama digir. Ma jiro hal nooc oo nashqad ah oo ku yaal xaashida birta la hubiyay, laakiin sidoo kale kakan oo ka kooban laba ama in ka badan laba nooc oo naqshad ah oo ku yaal dusha hal xaashi bir la hubiyay. Waxa kale oo lagu magacaabi karaa sida xaashida birta grid.
Halabuurka Kiimikada ee xaashida birta ah ee la dubay ee kulul
Gooshayada birta ah ee la dubay ee kulul waxaa badanaa lagu duubaa birta qaab dhismeedka kaarboonka ee caadiga ah. Qiimaha kaarboonku wuxuu gaari karaa in ka badan 0.06%,0.09% ama 0.10%,qiimaha ugu badan waa 0.22%. Qiimaha ka kooban silikon wuxuu u dhexeeyaa 0.12-0.30%, manganese qiimihiisu wuxuu u dhexeeyaa 0.25-0.65%, iyo fosfooraska iyo baaruuddu waxay caadi ahaan ka yar yihiin 0.045%.
Xashiishka birta ah ee kululaynta leh ayaa leh faa'iidooyin kala duwan, sida quruxda muuqaalka, iska caabinta iyo badbaadinta alaabta birta. Guud ahaan, si loo tijaabiyo hantida makaanikada ama tayada xaashida birta ah ee duuban ee kulul, heerka qaabaynta iyo dhererka qaabka waa in marka hore la tijaabiyaa.

Codsiga saxanka birta ah ee la dubay ee kulul
Xaashiyaha birta ah ee kulul ee duuban waxaa badanaa loo isticmaali karaa warshadaha dhismaha markabka, kuleyliyaha, baabuurta, cagaf-cagafyada, dhismaha tareenka iyo dhismaha. Faahfaahin ahaan, waxaa jira baahiyo badan oo loogu talagalay xaashida birta ah ee kulul ee duuban si loo sameeyo sagxadda, jaranjarada goobta aqoon-is-weydaarsiga, baallaha qaabka shaqada, sagxada markabka, sagxada baabuurka iyo wixii la mid ah.
Xirmada & Gaadhsiinta Saxanka Birta ee La Dulmaray ee Kulul
Alaabta loo diyaarinayo baakooyinka waxaa ka mid ah: bir dhuuban, suunka birta ceeriin ama birta xagasha geeskeeda, warqad farshaxan ama xaashi galvanized ah.
Saxanka birta ah ee kulul ee duuban waa in lagu duuduubaa warqad farshaxan ah ama xaashi galvanized ah oo dibadda ah, waana in lagu xidhaa bir cidhiidhi ah, saddex ama laba xariijimo bir ah oo cidhiidhi ah oo jihada dheer u socota, iyo saddexda ama labada kale ee kale ee leexsan. Intaa waxaa dheer, si loo hagaajiyo xaashida kulul ee duuban ee birta ah, loogana fogaado falinka cidhifka ah waa in la jebiyo, suunka birta cayriin ee loo gooyay labajibbaaran waa in la hoos geliya birta cidhiidhiga ah ee cidhifka ah. Dabcan, xaashida birta ah ee kulul ee duuban ayaa lagu xidhi karaa iyada oo aan lahayn warqad farshaxan ama galvanized. Waxay kuxirantahay baahida macmiilka.
Iyadoo la tixgalinayo gaadiidka laga soo qaadayo shiididda ilaa dekedda raritaanka, baabuurka sida caadiga ah waa la isticmaali doonaa. Iyo tirada ugu badan ee baabuur kasta waa 40 mt.
