Litaba - "E akaretsang" Poleiting ea Tšepe ea Khabone

Poleiti ea tšepe ea khabone ke e 'ngoe ea lihlopha tsa motheo tsa thepa ea tšepe. E thehiloe holim'a tšepe, e nang le khabone e pakeng tsa 0.0218%-2.11% (tekanyetso ea indasteri), 'me ha e na kapa ha e na karolo e nyane ea likarolo tsa ho kopanya. Ho ea ka tekanyo ea khabone, e ka aroloa ka:
Tšepe e tlaase ea khabone(C≤0.25%): ho tiea ho hotle, ho bonolo ho ho sebetsana, Q235 ke ea sehlopha sena;
Tšepe ea khabone e mahareng(0.25%
Tšepe e phahameng ea khabone(C>0.6%): ho thatafala ho hoholo haholo le ho robeha ha bonolo ho hoholo.

Tšepe ea k'habone ea Q235: tlhaloso le liparamente tsa mantlha (tekanyetso ea GB/T 700-2006)

Thepa ea mechini:
Matla a tlhahiso: ≥235MPa (botenya ≤16mm)
Matla a ho thapolla: 375-500MPa
Ho lelefatsa: ≥26% (botenya ≤16mm)

Boitsebiso le Tshebetso

Boitsebiso:Lisebelisoa tse tloaelehileng li kenyelletsaGR.B, X42, X46, X52, X56, X60, X65, X70, jj.

Litšobotsi tsa Tshebetso
Matla a Phahameng: E khona ho mamella khatello e phahameng e hlahisoang ke maro a kang oli le khase ea tlhaho nakong ea lipalangoang.
Matla a Phahameng: Ha ho bonolo ho robeha ha ho e-na le tšusumetso ea kantle kapa liphetoho tsa jeoloji, ho netefatsa ts'ebetso e sireletsehileng ea phaephe.
Khanyetso e Ntle ea Ts'enyeho: Ho ya ka ditikoloho le mecha e fapaneng ya tshebediso, ho kgetha thepa e nepahetseng le mekgwa ya kalafo ya bokahodimo ho ka hanela ho bola ka katleho le ho eketsa bophelo ba tshebeletso ya phaephe.

Litšobotsi tsa "mohlabani ea nang le mahlakore a tšeletseng" oa Q235

Tshebetso e Hloahloa ea Ts'ebetso
Ho tjheseletsa: Ha ho hlokahale ho futhumatsa esale pele, ho loketse ho tjheseletsa arc, ho tjheseletsa ka khase le ditshebetso tse ding (tse kang ho tjheseletsa sebopeho sa tshepe ya kaho);
Ho ba le Sebopeho se Batang: E ka kobeha le ho hatakeloa habonolo (mohlala: khetla ea lebokose la kabo, mothapo oa moea o kenang);
Ho sebetsa ha mechine: Tshebetso e tsitsitseng tlasa ho seha ka lebelo le tlase (tshebetso ya dikarolo tsa mochini).
Tekanyo e Felletseng ea Mekaniki

Matla khahlanong le ho tiea: Matla a tlhahiso ea 235MPa a ela hloko ho hanyetsa mojaro le tšusumetso (ha ho bapisoa le 195MPa ea Q195);
Phekolo ea Bokaholimo e Ikamahanya le Maemo: Ho bonolo ho penta ka galvanize le ho fafatsa pente (joalo ka li-guardrails, li-keel tsa tšepe tse bobebe).
Bokgoni bo Ikhethang ba Moruo
Litšenyehelo li ka tlase ho 15%-20% ho feta tsa tšepe e matla e nang le motswako o tlase (joalo ka Q345), e loketseng ts'ebeliso e kholo.
Tekanyo e Phahameng ea Maemo
Botenya bo tloaelehileng: 3-50mm (setoko se lekaneng, se fokotsa potoloho ea ho iketsetsa);
Maemo a ho kenya tshebetsong: GB/T 700 (ya lapeng), ASTM A36 (e lekanang le ya matjhaba).

Reka le ho Sebelisa "Tataiso ea ho Qoba"

Tlhahlobo ea Boleng:
Ponahalo: ha ho na mapetso, maqeba, menahano (tekanyetso ea sebopeho sa poleiti ea GB/T 709);
Tiisetso: Hlahloba sebopeho, thepa ea mechini le tlaleho ea ho lemoha liphoso (ho hlokahala ho lemoha liphoso tsa UT bakeng sa likarolo tsa bohlokoa tsa sebopeho).
Leano la ho thibela ho bola:
Ka tlung: pente e thibelang mafome (joalo ka pente e khubelu ea loto) + topcoat;
Kantle: hot-ina galvanizing (ho koahela ≥85μm) kapa ho fafatsa ka fluorocarbon.
Tlhokomeliso ea ho tjheseletsa:
Khetho ea thupa ea ho tjheseletsa: Letoto la E43 (joalo ka J422);
Poleiti e tšesaane(≤6mm): ha ho hlokahale ho futhumatsa esale pele, poleiti e teteaneng (>20mm): futhumatsa esale pele 100-150℃ ho thibela mapetso.
