CS-B Galvanized Rolled Steel Coil

ʻO ka pepa Galvanized e pili ana i ka pā kila i uhi ʻia me kahi papa zinc. ʻO ka Galvanizing kahi ʻano hana antirust maikaʻi a hoʻohana pinepine ʻia. Ma kahi o ka hapalua o ka hana zinc o ka honua i hoʻohana ʻia i kēia hana.
ʻO ka pepa kila Galvanized ka mea e pale ai i ka corrosion ma ka ʻili o ka pā kila a hoʻolōʻihi i kona ola lawelawe. Hoʻopili ʻia kahi papa o ka zinc metala ma ka ʻili o ka pā kila, i kapa ʻia ʻo galvanized steel plate.

Ua hele ka Galvanized Steel Coils i ke kaʻina hana kemika e mālama iā lākou mai ka ʻinoʻino. Ua uhi ʻia ke kila i nā ʻāpana zinc no ka mea ʻaʻole e hoʻouka ka ʻōpala i kēia metala pale. ʻO ke ʻano nui o ka hana ʻana i ke kila e pale aku i ka ʻinoʻino, ʻo ia ka hoʻohui ʻana me kekahi metala ʻē aʻe, ʻo ka zinc. , e like me ka pena, no ka mea, ʻaʻole ia e ʻaʻahu wale i ke kila; lilo maoli ia i ʻāpana o ia mea.

ʻO ka galvanization wela ke ʻano o ka galvanization. ʻO ia ke kaʻina hana o ka uhi ʻana i ka hao a me ke kila me ka zinc, e hui pū me ka ʻili o ka metala kumu i ka wā e hoʻokomo ai i ka metala i loko o kahi ʻauʻau o ka zinc hehee ma kahi o 840 ° F( 449°C). Ke hōʻike ʻia i ka lewa, hana ka zinc maʻemaʻe (Zn) me ka oxygen (O2) e hana i ka zinc oxide (ZnO), kahi e hana hou ai me ka carbon dioxide (CO2) e hana i ka zinc carbonate (ZnCO3), a maʻamau. ʻeleʻele ʻeleʻele, mea ikaika kūpono e pale ai i ke kila ma lalo mai ka ʻino hou aʻe i nā manawa he nui. Hoʻohana nui ʻia ke kila Galvanized i nā noi kahi e pono ai ke pale ʻana i ka corrosion me ka ʻole o ke kumu kūʻai o ke kila kila, a ua manaʻo ʻia ʻoi aku ka maikaʻi o ke kumukūʻai a me ke ola-pōkole. Hiki ke ʻike ʻia e ke ʻano crystallization ma ka ʻili (i kapa pinepine ʻia he "spangle").
