I nā makahiki i hala iho nei, ua lilo nā pā kila kila 304 i mea kaulana loa. Ke hoʻohālikelike ʻia me 304 mau pā kila kila, ʻoi aku ka nāwaliwali o ka pale ʻana o ka 201 stainless steel. ʻAʻole ia e ʻōlelo ʻia e hoʻohana ʻia i loko o ka ʻāina kaiapuni pinepine a me ke anuanu a i ʻole ka ʻāina ʻo Pearl River Delta. Hoʻohana nui ʻia i nā wahi haʻahaʻa haʻahaʻa a me nā wahi maloʻo. No ka ʻoihana hoʻolālā a me ka ʻoihana hoʻonaninani me nā koina haʻahaʻa a me ka maikaʻi, ʻo 304 stainless steel plate he kūpaʻa maikaʻi i ka corrosion a hiki ke hoʻohana pinepine ʻia i nā panalāʻau haʻahaʻa a i ʻole nā ​​kahakai hikina hikina, e like me Guangdong, Fujian, Zhejiang a me nā kūlanakauhale kahakai ʻē aʻe. Ma muli paha o ka ʻokoʻa o ka pale ʻana i ka corrosion, ʻoi aku ka haʻahaʻa o ke kumu kūʻai o 201 ma mua o ka 304 mau pā kila kila, no laila e hoʻohālike kekahi mau mea kūʻai hewa e hoʻohana pono i nā loopholes he 304 mau papa kila kila a kūʻai aku iā lākou i waho o ka honua e loaʻa ai ka waiwai nui. ʻO ia ʻano palaka e lawe mai i nā pilikia palekana i nā mea kūʻai aku.

Pehea e hoʻoponopono ai i nā papa kila kila 201 a me 304 me ka ʻole o nā hōʻailona anti-hoʻopunipuni? Hāʻawi ʻia kēia mau ʻano ʻekolu e aʻo iā ʻoe e ʻike maʻalahi i nā pā kila stainless 201 a me 304:

1.ʻO ka ʻili o 201 a me 304 mau papa kila kila ma lalo o ka honua. No laila, i ka wā e hoʻokolokolo 'ia e kanaka maka a me ka lima hoopa: 304 kuhiliʻole kila pā i ka maikai glossiness a me ka alohilohi, a me ka lima hoʻopā aku mea laumania, oiai 201 kuhiliʻole kila pāʻeleʻele aʻaʻohe olinolino, a me ka hoʻopā mea 'oʻoleʻa a uneven. Manaʻo. Eia hou, hoʻomaʻemaʻe i kou mau lima me ka wai a hoʻopā i nā mea kila kila ʻelua. Ma hope o ka hoʻopā ʻana, ʻoi aku ka maʻalahi o ka holoi ʻana i nā manamana lima paʻa wai ma ka papa 304, akā ʻaʻole maʻalahi ka 201 e holoi.
2.E hoʻohana i ka mea wili e hoʻokomo i ka huila wili a wili mālie a poni i nā papa ʻelua a i ʻole nā ​​papa. I ka wā e wili ai, ʻoi aku ka lōʻihi, ʻoi aku ka mānoanoa, a ʻoi aku ka lōʻihi o nā kukuna o ka mea 304, ʻoi aku ka pōkole, ʻoi aku ka lahilahi a me ka liʻiliʻi. I ka wā e wili ai, pono e māmā ka ikaika, a ʻo nā ʻano ʻelua o ka ikaika wili e like me ka maʻalahi, i maʻalahi ke ʻike.
3.E hoʻopili i ka paʻi paʻi ʻia ʻana i ʻelua ʻano papa kila kuhili ʻole. Ma hope o 2 mau minuke, e nānā i ka loli o ke kala o ke kila kila ma ka ʻāpana i hamo. He pōʻeleʻele ka waihoʻoluʻu no 201, a ʻo ke kala keʻokeʻo a hoʻololi ʻole ʻia no 304 pā kila kila.
