ʻO ke kiʻekiʻe kiʻekiʻe Hot Dipped Prepainted Galvanized Color Zinc Coated PPGI PPGL Prepainted Steel Coil

♦ PPGI coil substrate classification

1.Hot dip galvanized substrate
ʻO ka huahana i loaʻa ma ka hoʻopili ʻana i ka mea hoʻoheheʻe kūlohelohe ma luna o ka ʻili kila wela wela ka ʻāpana kala i uhi ʻia.Ma waho aʻe o ka hopena pale o ka zinc, ʻo ka uhi kūlohelohe ma luna o ka ʻili o ka ʻili wela wela i hoʻopaʻa ʻia i ke kala i hoʻopaʻa ʻia i ke ʻano o ka insulation a me ka pale ʻana, ka pale ʻana i ka pala, a ʻoi aku ka lōʻihi o ke ola o ka lawelawe ma mua o ka wela wela. pepa galvanized.He 180g/m2 ka maʻiʻo zinc o ka substrate galvanized hot-dip (ʻaoʻao pālua), a ʻo 275g/m2 ka nui galvanized o ka substrate galvanized hot-dip no ke kūkulu ʻana i waho.

2.Hot-dip Al-Zn substrate
Hoʻohana ʻia ka ʻili hao hao wela (55% Al-Zn) ma ke ʻano he pani pani hou, a ʻo ka ʻike o ka aluminika a me ka zinc he 150g/㎡ (ʻaoʻao pālua).He 2-5 mau manawa ka pale ʻana i ka corrosion o ka pepa wela wela.ʻO ka hoʻohana mau ʻana a i ʻole ka hoʻohana ʻana i nā mahana a hiki i 490°C ʻaʻole ia e hoʻoheheʻe ʻia a hoʻohua ʻia ka unahi.ʻO ka hiki ke hoʻohālikelike i ka wela a me ka māmā he 2 mau manawa ma mua o ke kila galvanized wela, a ʻoi aku ka nui o ka reflectivity ma mua o 0.75, ʻo ia kahi mea hale kūpono no ka mālama ʻana i ka ikehu.

3.Electro-galvanized substrate
Hoʻohana ʻia ka pepa electro-galvanized ma ke ʻano he substrate, a ʻo ka huahana i loaʻa ma ka uhi ʻana i ka pena organik a me ka bakena ʻo ia ka pepa i uhi ʻia i ka kala electro-galvanized.Ma muli o ka lahilahi o ka papa zinc o ka pepa electro-galvanized, ʻo ka zinc content o ka pepa electro-galvanized he 20/20g/m2, no laila ʻaʻole kūpono kēia huahana no ka hoʻohana.E hana i nā pā, nā hale, a me nā mea ʻē aʻe ma waho.Akā ma muli o kona hiʻohiʻona nani a me ka hana hoʻoponopono maikaʻi loa, hiki ke hoʻohana nui ʻia i nā mea pono hale, nā leo, nā lako kila, nā mea hoʻonaninani, etc.

♦ PPGI/PPGL coil substrate hiʻohiʻona

Pāpaʻi galvanized wela:

Hoʻokomo ʻia ka pā kila lahilahi i loko o kahi ʻauʻau zinc i hoʻoheheʻe ʻia e hana i kahi papa zinc e pili i ka ʻili.Loaʻa i kēia pā galvanized ka hoʻopili maikaʻi a me ka weldability o ka uhi.

Pāpaʻa Al-Zn wela:

Hoʻopili ʻia ka huahana me 55% AL-Zn, he hana anti-corrosion maikaʻi loa, a ʻoi aku kona ola lawelawe ma mua o ʻehā mau manawa o ke kila galvanized maʻamau.He mea pani ia o ka pepa galvanized.

Electro-galvanized substrate: 

ʻOi aku ka lahilahi o ka uhi ʻana, a ʻaʻole maikaʻi kona pale ʻana i ka corrosion e like me ka substrate galvanized hot-dip.

♦ PPGI coil huahana hiʻona

(1) He lōʻihi kona lōʻihi, a ʻoi aku ka lōʻihi o kona pale ʻana i ka corrosion ma mua o ke kila galvanized;

(2) He maikaʻi kona pale ʻana i ka wela a ʻoi aku ka liʻiliʻi o ka discoloration ma ke kiʻekiʻe wela ma mua o ke kila galvanized;

(3) Loaʻa iā ia ka reflectivity thermal maikaʻi;

(4) Loaʻa iā ia ka hana hana a me ka hoʻoulu ʻana i ka hana e like me ka galvanized steel sheet;

(5) He hana kuʻihao maikaʻi.

(6) Loaʻa iā ia kahi lakio kumu kūʻai maikaʻi, hana paʻa a me ke kumukūʻai hoʻokūkū loa.No laila, inā paha i hoʻohana nui ʻia nā mea hoʻolālā, nā ʻenekinia a i ʻole nā ​​​​mea hana i nā hale ʻoihana, nā hale kila a me nā hale kīwila, e like me nā puka hale kaʻa, nā ʻauwai a me nā hale.

♦ Ppgi coil palapala noi

He māmā, nani a loaʻa nā ʻano anti-corrosion maikaʻi nā coils Ppgi, a hiki ke hana pololei ʻia.Hoʻokaʻawale ʻia nā kala i ke keʻokeʻo hina, ʻulaʻula moana a me ka ʻulaʻula.Hoʻohana nui ʻia lākou i ka hoʻolaha ʻana, ke kūkulu ʻana, nā mea pono hale, nā mea uila, nā lako a me ka halihali.ʻOihana.
