Ke lintho life tse hlokahalang bakeng sa li-roller tsa Photovoltaic Welding Strip Rolling Mill

      Leloala le roalang la Photovoltaic Welding Strip Rolling Mill ke karolo ea mantlha e sebetsang, e hokahanang ka kotloloho le ho pepeta terata ea koporo (thepa e tala). E hloka ho finyella litlhoko tsa matla a phahameng, ho hanyetsa ho apara ho phahameng, botsitso bo phahameng ba mahlakoreng, le boreleli ba holim'a metsi ka nako e le 'ngoe ho netefatsa boholo bo nepahetseng (ho mamellana ha botenya hangata ≤± 0.002mm) le boleng ba holim'a photovoltaic welding strip. Khetho ea thepa e lokela ho ipapisa le litlhoko tse latelang tsa mantlha:

1,Litlhoko tsa mantlha (boemo ba ts'ebetso)

      Ho thata ka ho fetelletseng le ho se sebetse ha leloala ho hloka extrusion ea nako e telele ea terata ea koporo (bothata ba koporo bo ka ba HB30-50), 'me bokaholimo bo tloaetse ho roala ka lebaka la likhohlano le extrusion. Haeba boima bo sa lekana, bo tla etsa hore leloala le pota-potiloeng le be concave 'me ho nepahala ha dimensional ho fokotsehe, ho ama ka ho toba ho lumellana ha sekhahla sa tjheseletsa. Ka hona, thepa ea rolara e hloka ho ba le boima ba bokaholimo ba ≥ HRC60 (Bothata ba Rockwell), mme substrate e hloka ho ba le ts'ehetso e lekaneng ea ho tiea ho qoba ho robeha ho thata le ho robeha.

      Excellent dimensional stability (low the thermal expansion coefficient): Nakong ea ts'ebetso ea ho roala, mocheso oa sebaka o hlahisoa ke ho ferekana pakeng tsa leloala le roalang le thepa ea koporo. Haeba coefficient ea katoloso ea mocheso oa thepa e phahame haholo, e tla etsa hore boholo ba leloala le feto-fetohe le mocheso, e leng se etsang hore ho be le ho kheloha botenya ba lesela la weld. Ka hona, thepa e hloka ho ba le coefficient e tlaase ea ho atolosa mocheso (hangata e hlokahalang ho ba ≤ 12 × 10 ⁻⁶/℃, ka har'a 20-100 ℃) ho netefatsa botsitso ba dimensional nakong ea nako e telele.

      Boreleli bo phahameng ka ho fetesisa le ho batalla ha likhoele tsa ho tjheseletsa ha photovoltaic ho hloka litlhoko tse tiileng tsa boleng ba bokaholimo (ha ho na mengoapo, li-indentation, kapa matheba a oxidation), 'me boreleli ba bokaholimo ba leloala le rala ka kotloloho boemo ba bokaholimo ba lesela la welding. Ka hona, lintho tse bonahalang tsa leloala rolling e lokela ho ba ho le bonolo ho bentsa ho ea seipone boemo boreleli (Ra ≤ 0.02 μ m), 'me ha hoa lokela ho ba le likoli tse kang pores kapa inclusions ka hare ho lintho tse bonahalang ho qoba liphoso holim'a ka mor'a ho bentsa.

      Nakong ea ts'ebetso ea leloala le nang le mokhathala o motle le ho hanyetsa tšusumetso, leloala le bilikang le hloka ho mamella meroalo e fapaneng ea li-cyclic (compression, friction), e ka lebisang habonolo mapheong a mokhathala ha e sebelisoa nako e telele; Ho sa le joalo, ho feto-fetoha ha lebelo la terata ho ka baka litlamorao tsa hang-hang. Ka hona, thepa e hloka ho ba le matla a ho khathala ka bobeli (matla a mokhathala a kobehang ≥ 800MPa) le tekanyo e itseng ea ho tiea ho qoba ho phatloha kapa ho robeha ha leloala tlas'a mojaro oa nako e telele.

      Corrosion le oxidation resistance: Tikoloho e bilikang e ka kopana le mouoane oa metsi le ho lata matheba a oli moeeng, 'me mohala o latelang oa tjheseletsa o hloka ho hloekisoa pele ho kolobisoa ka thini. Haeba thepa ea rolara e le bonolo ho oxidation kapa corrosion, e tla etsa hore ho thehoe lera la oxide holim'a metsi, le silafatse bokaholimo ba lesela la welding. Ka hona, thepa e hloka ho ba le khanyetso e ntle ea kutu ea sepakapaka ka mocheso oa kamore le ho senyeha ho honyenyane ha tšilafalo ea oli, ho qoba oxidation ea bokaholimo le ho ebola.

2,Litlhoko tse thusang (litekanyo tsa ho sebetsa le tsa tlhokomelo)

      Machinability: Thepa e lokela ho ba bonolo ho etsa ho sila ka mokhoa o nepahetseng (ho netefatsa hore mamello e pota-potileng ea holim'a rolara ke ≤ 0.001mm) le polishing, ho qoba ho eketseha ha litšenyehelo ka lebaka la bothata bo phahameng ba ho sebetsa;

      Thermal conductivity: Tse ling tse lebelo le phahameng mabili li hloka tsamaiso ea ho pholisa le lisebelisoa tse nang le conductivity e itseng ea mocheso (joaloka hard alloy thermal conductivity ≥ 80W/(m · K)) ho thusa ho qhala ka nako e nepahetseng ea mocheso o tsitsitseng le ho netefatsa botsitso ba dimensional.
