Melemo le bofokoli ba poleiti ea tšepe e entsoeng ka aluminium-zinc

Litšepe tse chesang tsa dip dip li 'nile tsa sebelisoa haholo kahong, lisebelisoa tsa lapeng le liindasteri tse ling tse kholo ho tloha ha li hlaha. Ka lebaka la ho atolosoa ho tsoelang pele ha sebaka sa tšebeliso, sebopeho le thepa e fapaneng ea lihlahisoa ho poleiti ea tšepe li tsoela pele ho ntlafatsoa, ​​​​'me sephetho sa aluminium-zinc plated plated plated se phahametse poleiti ea tšepe e chesang-dip libakeng tse ling. Aluminium-zinc plated steel plated
Al-Zn composite aluminium-zinc plated plated plated e fumanoa ka ho qoelisoa hot-dip ka poleiti ea tšepe e kentsoeng ka serame e nang le matla a fapaneng le litlhaloso tsa botenya e le thepa ea motheo. Ho roala ho na le 55% aluminium, 43.5% zinki, 1.5% silicon le likarolo tse ling tsa mohlala.
Ts'ebetsong ea tlhahiso le ts'ebetsong, ts'ebetso ea aluminium-zinc plating e phahametse ea hot-dip galvanizing, haholo-holo likarolong tse latelang.
Ts'ebetso ea ts'ebetso
Ts'ebetso ea aluminium-zinc plated plated plated e tšoana le ea hot-dip galvanizing, e ka fihlelang ka botlalo litlhoko tsa ts'ebetso ea ho roala, ho hatakela, ho kobeha le mefuta e meng.
Khanyetso ea kutu
Teko e etsoa tlas'a motheo oa lakane ea tšepe e chesang-dip galvanized le aluminium-zinki e koahetsoeng ka tšepe e nang le botenya bo tšoanang, ho roala le ho phekola holim'a metsi. Aluminium-zinc plating e na le khanyetso e ntle ea kutu ho feta galvanizing e chesang, 'me bophelo ba eona ba ts'ebeletso ke makhetlo a 2-6 ho feta a poleiti e tloaelehileng ea galvanized.
Tshebetso ea ho bonahatsa leseli
Bokhoni ba zinki ea aluminized ho bonahatsa mocheso le khanya e habeli ea poleiti ea tšepe e entsoeng ka masenke, 'me ponahalo e kholo ho feta 0.70, e molemo ho feta 0.65 e boletsoeng ke EPA Enerav Star.
Ho hanyetsa mocheso
Lihlahisoa tse tloaelehileng tsa sekontiri se chesang hangata li sebelisoa ka mocheso o sa feteng 230 ℃, 'me li tla fetola' mala ho 250 ℃, ha poleiti ea aluminium-zinc e ka sebelisoa nako e telele ho 315 ℃ ntle le ho fetola 'mala. Kamora lihora tse 120 ho 300 ℃, phetoho ea 'mala oa poleiti ea tšepe e entsoeng ka aluminium-zinki e tšoaroang ke phihlello e thibelang mocheso e Baosteel e tlase haholo ho feta ea poleiti ea aluminium le poleiti e entsoeng ka aluminium.
thepa ea mochini
Thepa ea mochini ea aluminium-zinc plated steel plated e bonts'oa haholo ka matla a tlhahiso, matla a thata le bolelele. Letlapa le tloaelehileng la galvanized DC51D la 150g/m2 le na le matla a tlhahiso a 140-300mpa, matla a 200-330 le bolelele ba 13-25. Nomoro ea lebitso DC51D+AZ
Matla a lihlahisoa a aluminized zinki plated tšepe sheet le 150g/m2 aluminized zinki pakeng tsa 230-400mpa, tensile matla a pakeng tsa 230-550, le elongation seporo pakeng tsa 15-45.
Hobane aluminium-zinki e koahetsoeng ke tšepe ea alloy e phahameng haholo, e na le melemo e mengata le mefokolo e meng.
1. Ts'ebetso ea welding
Ka lebaka la ho eketseha ha thepa ea mechine, sekhahla sa ho roala bokaholimo ba substrate bo botle, 'me litaba tsa manganese li batla li le holimo, kahoo zinki ea aluminized e ke ke ea kolobisoa tlas'a maemo a tloaelehileng a tjheseletsa,' me e ka kopanngoa feela ke li-rivets le lihlopha tse ling. Mabapi le ho tjheseletsa, poleiti ea tšepe e chesang-dip e sebetsa hantle, 'me ha ho na bothata ba ho cheselletsa.
2. Ho tšoaneleha ha konkreite ea mocheso o mongobo
Sebopeho sa ho roala aluminium-zinki se na le aluminium, e atisang ho itšoara ka lik'hemik'hale ha e kopana ka ho toba le konkreite e nang le asiti e metsi. Ka hona, ha e tšoanelehe haholo ho etsa mapolanka a fatše.
