ʻOkoʻa ma waena opaipu galvanized mua ʻiaa mePaipu kila Galvanized Hot-DIP
1. ʻOkoʻa i ke kaʻina hana: Hoʻopili ʻia ka paipu galvanized wela ma ka hoʻokomo ʻana i ka paipu kila i loko o ka zinc heheʻe, ʻoiaipaipu galvanized mua ʻiaua uhi like ʻia me ka zinc ma luna o ka ʻili o ke kila kila ma o ke kaʻina hana electroplating.
2. Nā ʻokoʻa kūkulu: ʻO ka paipu galvanized wela-dip he huahana tubular, ʻoiai ʻo ka paipu kila pre-galvanized he huahana ʻoki me ka laulā nui a me ka mānoanoa liʻiliʻi.
3. Nā noi like ʻole: Hoʻohana nui ʻia nā paipu galvanized wela no ka lawe ʻana i nā wai a me nā kinoea, e like me nā paipu hoʻolako wai, nā paipu aila, a pēlā aku, ʻoiai ʻo nā paipu kila pre-galvanized e hoʻohana nui ʻia no ka hana ʻana i nā huahana metala like ʻole, e like me nā ʻāpana kaʻa, nā pūpū mīkini home a pēlā aku.
4. ʻOkoʻa ka hana anti-corrosion: ʻoi aku ka maikaʻi o ka hana anti-corrosion o ka paipu galvanized wela ma muli o ka papa galvanized mānoanoa, ʻoiai ʻo ka galvanized steel strip he hana anti-corrosion haʻahaʻa ma muli o ka papa galvanized lahilahi.
5. Nā kumukūʻai like ʻole: he paʻakikī a he pipiʻi ke kaʻina hana o ka paipu galvanized wela, ʻoiai he maʻalahi a he haʻahaʻa ke kumukūʻai o ke kaʻina hana o ka paipu kila galvanized.
Nānā ʻana i ka maikaʻi o nā paipu kila galvanized pre-galvanized a me ka hot-dip galvanized
1. Nānā ʻana i ke ʻano
Hoʻopau ʻili: ʻO ka nānā ʻana i ke ʻano o ka paipu kila e pili nui ana i ka palahalaha a laumania o ka ʻili o ka paipu kila, me ka ʻike ʻole ʻia o ka slag zinc, ka puʻupuʻu zinc, ke kau ʻana o ke kahe a i ʻole nā hemahema ʻē aʻe o ka ʻili. Pono ka ʻili paipu kila galvanized maikaʻi e laumania, ʻaʻohe pehu, ʻaʻohe māwae, ʻaʻohe puʻupuʻu zinc a i ʻole ke kau ʻana o ke kahe zinc a me nā hemahema ʻē aʻe.
Waihoʻoluʻu a me ke ʻano like: E nānā inā like a kūlike ke kala o ka paipu kila, a inā he ʻano like ʻole ka hoʻolaha ʻana o ka papa zinc, ʻoiai ma nā humuhumu a i ʻole nā wahi i hoʻopaʻa ʻia. ʻO ka paipu kila galvanized wela-dip maʻamau e ʻike ʻia he keʻokeʻo kālā a keʻokeʻo paha, ʻoiai ʻoi aku ka māmā o ke kala o ka paipu kila pre-galvanized.
2. Ke ana ʻana o ka mānoanoa o ka zinc
Ana Mānoanoa: Ana ʻia ka mānoanoa o ka papa zinc me ka hoʻohana ʻana i kahi ana mānoanoa i uhi ʻia (e laʻa me ke au magnetic a i ʻole ke au eddy). He mea nui kēia e hoʻoholo ai inā kūlike ka uhi zinc me nā koi maʻamau. ʻO ka paipu kila galvanized hoʻoluʻu wela he papa zinc mānoanoa, ma waena o 60-120 microns, a ʻo ka paipu kila galvanized mua he papa zinc lahilahi, ma waena o 15-30 microns.
ʻAno kaumaha (laʻana): Kaumaha ʻia nā laʻana e like me ke kūlana a ua helu ʻia ke kaumaha o ka papa zinc no kēlā me kēia ʻāpana e hoʻoholo ai i ka mānoanoa o ka papa zinc. Hoʻoholo pinepine ʻia kēia ma ke ana ʻana i ke kaumaha o ka paipu ma hope o ka pickling.
Nā koi maʻamau: No ka laʻana, ʻo GB/T 13912, ASTM A123 a me nā kūlana ʻē aʻe he mau koi maopopo no ka mānoanoa o ka papa zinc, a ʻokoʻa paha nā koi mānoanoa o ka papa zinc no nā paipu kila no nā noi like ʻole.
3. ʻO ke ʻano like o ka papa galvanized
ʻO ke ʻano o ka papa galvanized kiʻekiʻe he ʻano like, ʻaʻohe leakage a ʻaʻohe hōʻino post plating.
ʻAʻohe ʻulaʻula i loaʻa ma hope o ka hoʻāʻo ʻana me ka wai keleawe sulfate, e hōʻike ana ʻaʻohe leakage a i ʻole ka hōʻino post-plating.
ʻO kēia ke kūlana maʻamau no nā mea hoʻopili galvanized kiʻekiʻe e hōʻoia i ka hana maikaʻi loa a me ke ʻano.
4. Hoʻopili ikaika o ka papa galvanized
ʻO ke kāpili ʻana o ka papa galvanized he mea nui ia e hōʻike ana i ke ʻano o ka paipu kila galvanized, e hōʻike ana i ke kiʻekiʻe o ka paʻa o ka hui ʻana ma waena o ka papa galvanized a me ka paipu kila.
E hana ka paipu kila i kahi papa hui o ka zinc a me ka hao me ka hopena galvanizing ma hope o ka hopena o ka ʻauʻau luʻu ʻana, a hiki ke hoʻonui ʻia ka hoʻopili ʻana o ka papa zinc e ke kaʻina hana galvanizing ʻepekema a pololei.
Inā ʻaʻole e wehe maʻalahi ka papa zinc ke kī ʻia me ka mallet laholio, hōʻike ia i ka hoʻopili maikaʻi ʻana.
