Steel ili lapaʻau rust removal grade standard

E like me ka ʻōlelo ʻana, "ʻekolu ʻāpana pena, ʻehiku ʻāpana ʻāpana", a ʻo ka mea nui loa i ka uhi ʻana ʻo ia ka maikaʻi o ka mālama ʻana i ka ʻili o ka mea, kahi haʻawina kūpono e hōʻike ana i ka hopena o nā kumu o ka uhi ʻana i ka maikaʻi. ʻO ka mālama ʻana i ka ʻili o ka mea i helu ʻia no ka lakene o 40-50% o ka ʻoi aku.Hiki ke noʻonoʻo ʻia ke kuleana o ka mālama ʻana i ka ʻili i ka uhi.

Papa descaling: pili i ka maʻemaʻe o ka mālama ʻana i ka ʻili.

Nā Kūlana Lapaʻau ʻili kila

★ National standard GB8923-2011 wehewehe i ka descaling grade ★ 

[1] ʻO Jet a i ʻole ka pahū descaling

Hōʻike ʻia ka jet a i ʻole ka blast descaling e ka leka "Sa".ʻEhā mau māka descaling:

Sa1 Light Jet a i ʻole Blast Descaling

Me ka ʻole o ka hoʻonui ʻana, pono ʻole ka ʻili i ka momona a me ka lepo, a ʻaʻohe adhesions e like me ka ʻili oxidized maikaʻi ʻole, ka ʻōpala a me nā uhi pena.

ʻO Sa2 Hoʻopaʻa Pahū a i ʻole Hoʻopau Pahū

Me ka ʻole o ka hoʻonui ʻia, ʻaʻole ʻae ʻia ka ʻili mai ka momona ʻike ʻia a me ka lepo a me ka oxygen kokoke ʻole mai ka ʻili oxidized, ka ʻōpala, nā uhi a me nā haumia ʻē aʻe, e hoʻopili paʻa ʻia ke koena o ia mea.

Sa2.5 ʻO Jet Pahū Loa a i ʻole Hoʻohaʻahaʻa Pahū

Me ka ʻole o ka hoʻonui ʻia, ʻaʻole pono ka ʻili i ka momona ʻike ʻia, ka lepo, ka oxidation, ka ʻōpala, nā uhi a me nā haumia ʻē aʻe, a ʻo ke koena o nā mea haumia e ʻoki wale ʻia a i ʻole nā ​​​​mea ʻoniʻoni me ka māmā māmā.

Sa3 Jet a i ʻole ka hoʻoheheʻe ʻana o ke kila me ka ʻike maʻemaʻe

Me ka ʻole o ka hoʻonui ʻia ʻana, e kaʻawale ka ʻili mai ka aila ʻike ʻia, ka momona, ka lepo, ka ʻili i hoʻoheheʻe ʻia, ka ʻōpala, nā uhi a me nā haumia ʻē aʻe, a e loaʻa i ka ʻili ke kala metala like ʻole.

[2] Hoʻopau lima a me ka mea hana mana

Hōʻike ʻia ka descaling lima a me ka mea hana mana e ka leka "St".ʻElua mau papa o ka descaling:

St2 Hoʻopau lima a me ka mea hana mana

Me ka ʻole o ka hoʻonui ʻana, ʻaʻohe ʻaila i ʻike ʻia, ka momona a me ka lepo, a ʻaʻole i hoʻopili maikaʻi ʻia i ka ʻili oxidized, ka ʻōpala, nā uhi a me nā haumia ʻē aʻe.

ʻO St3 E like me St2 akā ʻoi aku ka maikaʻi, pono e loaʻa i ka ʻili ke ʻano metala o ka substrate.

【3】Hoʻomaʻemaʻe ahi

Me ka ʻole o ka hoʻonui ʻia, ʻaʻohe aila ʻike ʻia ka ʻili, ka momona, ka lepo, ka ʻili i hoʻoheheʻe ʻia, ka ʻōpala, nā ʻili a me nā haumia ʻē aʻe, a ʻo nā ʻāpana ʻē aʻe e hoʻololi wale i ka ʻili.

Papa hoʻohālikelike ma waena o kā mākou maʻamau descaling a me ka maʻamau descaling e like

'Ōlelo Aʻo: ʻOi aku ka koʻikoʻi o ka Sp6 ma SSPC ma mua o Sa2.5, ʻo Sp2 ka hoʻoheheʻe ʻana i ka pulupulu uea manual a ʻo ka Sp3 ka hoʻopau ʻana i ka mana.

ʻO nā palapala hoʻohālikelike o ka ʻili kila a me ka jet descaling grade penei:
