Dab tsi yog cov khoom xav tau rau cov menyuam ntawm Photovoltaic Vuam Sawb Rolling Mill

      Lub dov zeb ntawm Photovoltaic Vuam Sawb Rolling Mill yog cov tseem ceeb ua haujlwm tivthaiv, uas ncaj qha hu thiab nyem tooj liab hlau (cov khoom siv raw). Nws yuav tsum tau ua kom tau raws li qhov yuav tsum tau muaj zog, siab hnav tsis kam, siab ruaj khov, thiab nto smoothness nyob rau tib lub sij hawm kom paub meej qhov loj me me (thickness kam rau ua feem ntau ≤ ± 0.002mm) thiab nto zoo ntawm photovoltaic vuam sawb. Kev xaiv cov khoom siv yuav tsum hloov raws li cov cai hauv qab no:

1,Cov khoom siv tseem ceeb (kev ua tau zoo dimension)

      Lub hardness tsis tshua muaj siab thiab hnav tsis kam ntawm cov dov zeb yuav tsum tau siv lub sij hawm ntev extrusion ntawm tooj liab hlau (tooj liab hardness yog hais txog HB30-50), thiab nto yog nquag hnav vim kev sib txhuam thiab extrusion. Yog hais tias lub hardness yog tsis txaus, nws yuav ua rau lub dov zeb nto yuav tsum concave thiab lub dimensional raug txo, ncaj qha cuam tshuam lub uniformity ntawm vuam sawb thickness. Yog li ntawd, cov khoom siv rau cov menyuam yuav tsum muaj qhov tawv tawv ntawm ≥ HRC60 (Rockwell hardness), thiab cov substrate yuav tsum muaj kev txhawb nqa txaus kom tsis txhob muaj qhov tawv thiab tawg.

      Kev ruaj ntseg zoo heev (tsis tshua muaj thermal expansion coefficient): Thaum lub sij hawm dov txheej txheem, cov cua sov hauv zos yog tsim los ntawm kev sib txhuam ntawm cov dov zeb thiab cov khoom siv tooj liab. Yog tias cov khoom siv thermal expansion coefficient siab dhau lawm, nws yuav ua rau cov dov zeb loj tuaj yeem hloov pauv nrog qhov kub thiab txias, ua rau muaj qhov sib txawv ntawm qhov tuab ntawm cov hlua weld. Yog li, cov khoom siv yuav tsum muaj qhov qis qis qis thermal expansion coefficient (feem ntau yuav tsum yog ≤ 12 × 10 ⁻⁶ / ℃, nyob rau hauv thaj tsam ntawm 20-100 ℃) kom ntseeg tau qhov kev ruaj ntseg ntawm lub sijhawm ntev dov.

      Qhov siab heev ntawm qhov smoothness thiab flatness ntawm photovoltaic vuam strips yuav tsum tau nruj nto zoo raws li qhov yuav tsum tau (tsis muaj khawb, indentations, los yog oxidation me ntsis raug tso cai), thiab lub nto smoothness ntawm lub dov zeb ncaj qha txiav txim lub nto ntawm lub vuam sawb. Yog li ntawd, cov khoom ntawm lub tshuab dov yuav tsum yooj yim polish rau daim iav qib smoothness (Ra ≤ 0.02 μ m), thiab yuav tsum tsis txhob muaj qhov tsis xws luag xws li pores lossis inclusions hauv cov khoom kom tsis txhob muaj qhov tsis xws luag tom qab polishing.

      Thaum lub sijhawm ua haujlwm ntawm lub tshuab dov nrog kev qaug zog zoo thiab kev cuam tshuam tsis zoo, lub tshuab dov yuav tsum tiv taus cov khoom sib txawv ntawm cov khoom sib txawv (compression, kev sib txhuam), uas tuaj yeem yooj yim ua rau qaug zog tawg yog siv rau lub sijhawm ntev; Lub caij no, kev hloov pauv hauv cov xaim tso nrawm tuaj yeem ua rau muaj kev cuam tshuam sai sai. Yog li ntawd, cov khoom yuav tsum muaj ob qho tib si siab qaug zog (bending qaug zog zog ≥ 800MPa) thiab ib tug tej degree ntawm toughness kom tsis txhob tawg los yog ntug breakage ntawm dov zeb nyob rau hauv lub sij hawm ntev load.

      Corrosion thiab oxidation tsis kam: Qhov chaw dov tuaj yeem nkag mus rau hauv cov dej vapor thiab cov roj stains hauv huab cua, thiab cov hlua vuam tom ntej yuav tsum tau ntxuav ua ntej tin plating. Yog tias cov khoom siv rau cov menyuam yaus ua rau oxidation lossis corrosion, nws yuav ua rau tsim cov oxide txheej rau ntawm qhov chaw, kis kab mob ntawm qhov chaw vuam. Yog li ntawd, cov khoom siv yuav tsum muaj kev tiv thaiv zoo rau atmospheric corrosion ntawm chav tsev kub thiab me ntsis roj paug corrosion, kom tsis txhob nto oxidation thiab tev.

2,Cov kev cai pab txhawb (kev ua thiab kev saib xyuas qhov ntev)

      Machinability: Cov khoom siv yuav tsum yooj yim rau kev ua tiav kev sib tsoo (kom paub tseeb tias qhov kev sib tw ntawm cov menyuam nto yog ≤ 0.001mm) thiab polishing, zam kev nce nqi vim kev ua haujlwm siab;

      Thermal conductivity: Qee qhov kev kub ceev dov mills xav tau cov tshuab cua txias thiab cov khoom siv nrog qee yam thermal conductivity (xws li cov hlau alloy thermal conductivity ≥ 80W / (m · K)) los pab kom lub sij hawm dissipation ntawm kev sib txhuam ntawm tshav kub thiab ntxiv kom muaj kev ruaj ntseg.
