He aha nā mea e pono ai no nā wili o ka Photovoltaic Welding Strip Rolling Mill

      ʻO ka wili wili o Photovoltaic Welding Strip Rolling Mill ka mea hana koʻikoʻi, e hoʻopili pololei a ʻomi i ka uea keleawe (raw material). Pono ia e hoʻokō i nā koi o ka ikaika kiʻekiʻe, ke kūpaʻa lole kiʻekiʻe, ke kūpaʻa kiʻekiʻe kiʻekiʻe, a me ka maʻemaʻe o ka ʻili i ka manawa like e hōʻoia i ka nui pololei (ʻo ka mānoanoa tolerance maʻamau ≤± 0.002mm) a me ka maikaʻi o ka ili o ka photovoltaic welding strip. Pono ke koho ʻana i nā mea pono e pili ana i nā koi kumu:

1 、Koi waiwai kumu (ka nui hana)

      ʻO ka paʻakikī kiʻekiʻe loa a me ke kūpaʻa ʻana o ka wili wili e koi ai i ka extrusion lōʻihi o ka uea keleawe (ʻo ka paʻakikī keleawe e pili ana iā HB30-50), a ua maʻalahi ka ʻili ma muli o ka friction a extrusion. Inā ʻaʻole lawa ka paʻakikī, e hoʻohaʻahaʻa ʻia ka ʻili o ka wili wili a me ka emi ʻana o ka pololei o ke ana, e pili pono ana i ka like ʻole o ka mānoanoa welding strip. No laila, pono ka ʻili o ka ʻili o ka ʻili o ≥ HRC60 (Rockwell hardness), a ʻo ka substrate e loaʻa i ke kākoʻo paʻakikī e pale aku i ka haʻihaʻi paʻakikī.

      ʻOi aku ka maikaʻi o ka paʻa ʻana (koefficient hoʻonui wela haʻahaʻa): I ka wā o ka ʻōwili ʻana, hoʻokumu ʻia ka wela kūloko e ka paio ma waena o ka wili wili a me ka mea keleawe. Inā kiʻekiʻe loa ka pānaehana hoʻonui wela o ka mea, e hoʻololi i ka nui o ka wili wili me ka wela, e hopena i ka ʻae ʻana i ka mānoanoa o ka weld strip. No laila, pono e loaʻa i ka mea haʻahaʻa haʻahaʻa linear thermal expansion coefficient (ʻo ka mea maʻamau he ≤ 12 × 10 ⁻⁶ / ℃, ma ka laulā o 20-100 ℃) e hōʻoia i ka paʻa o ka dimensional i ka wā lōʻihi.

      ʻO ka maʻalahi o ka ʻili kiʻekiʻe a me ka palahalaha o nā paʻi kuʻi kiʻi kiʻi kiʻi e koi ai i nā koi koʻikoʻi o ka ʻili (ʻaʻole ʻae ʻia nā ʻōpala, nā indentations, a i ʻole nā ​​​​wahi oxidation), a ʻo ka maʻalahi o ka wili wili e hoʻoholo pololei i ke ʻano o ka ʻili o ka ʻili. No laila, pono e maʻalahi nā mea o ka wili wili i ka laumania o ke aniani kiʻekiʻe (Ra ≤ 0.02 μm), a ʻaʻohe hemahema e like me nā pores a i ʻole ke komo ʻana i loko o ka mea e pale ai i nā hemahema o ka ʻili ma hope o ka polishing.

      I ka wā o ka hana ʻana o ka wili wili me ka luhi maikaʻi a me ke kūʻē ʻana i ka hopena, pono ka wili ʻōwili e kū i nā ukana cyclic variable (hoʻopiʻi, friction), hiki ke alakaʻi maʻalahi i nā māwae luhi inā hoʻohana ʻia no ka manawa lōʻihi; I kēia manawa, hiki i ka loli ʻana o ka wikiwiki o ka hoʻomoe ʻana i ka uwea ke hopena i nā ukana hopena koke. No laila, pono e loaʻa i ka mea waiwai ka ikaika luhi kiʻekiʻe (ke kulou ʻana i ka ikaika luhi ≥ 800MPa) a me kahi pae o ka paʻakikī e pale aku ai i ka haki ʻana a i ʻole ka haki ʻana o ka wili wili ma lalo o ka ukana lōʻihi.

      ʻO ka pale ʻana a me ka pale ʻana: Hiki ke hoʻopili ʻia ke kaiapuni ʻōwili me ka mahu wai a ʻike i nā ʻaila ʻaila i ka lewa, a pono e hoʻomaʻemaʻe ʻia ke kaula kuʻi ma hope ma mua o ka hoʻopaʻa ʻia ʻana. Inā maʻalahi ka mea wili i ka oxidation a i ʻole ka corrosion, e hoʻokumu ʻia kahi papa oxide ma luna o ka ʻili, e hoʻohaumia i ka ʻili o ke kaula kuʻi. No laila, pono e loaʻa i ka mea waiwai ke kū'ē maikaʻi i ka corrosion o ka lewa ma ka wela o ka lumi a me ka corrosion pollution ʻaila liʻiliʻi, e pale aku i ka oxidation a me ka peeling.

2 、Nā koi kōkua (nā ana hoʻoponopono a mālama ʻia)

      Hiki i ka mīkini: Pono ka mea maʻalahi e hana i ka wili pololei (e hōʻoia i ka hoʻomanawanui ʻana o ka ʻili o ka ʻili he ≤ 0.001mm) a me ka polishing, e pale ana i ka piʻi ʻana o ke kumukūʻai ma muli o ka paʻakikī o ka hoʻoili ʻana;

      ʻO ka hoʻoili wela: ʻO kekahi mau mīkini wili kiʻekiʻe e koi aku i nā ʻōnaehana hoʻomaha a me nā mea me kekahi mau conductivity wela (e like me ka paʻa paʻa paʻa thermal conductivity ≥ 80W/(m · K)) e hoʻomaʻamaʻa i ka hoʻohemo ʻana o ka wela frictional a hōʻoia hou i ke kūpaʻa dimensional.
