Enamel

enamel,ma ke ʻano he mea hoʻonaninani papa lōʻihi a me nā mea pale, hoʻohana nui ʻia i ka hana ʻoihana a me ke ola o kēlā me kēia lā.ʻAʻole ia he nani a lōʻihi hoʻi, akā he kūpaʻa kemika maikaʻi a me ke kūpaʻa corrosion.Mai ka hiʻohiʻona o ka hana ʻenehana, ʻo ke kaʻina hana o ka enamel kahi kaʻina hana paʻakikī e hoʻohui i ka ʻepekema waiwai, ka ʻenekinia kemika, a me ka ʻenehana hana maikaʻi, e pili ana i ke koho ʻana i nā mea maka, ka hoʻomākaukau ʻana, ka uhi ʻana, a me ke kī ʻana.

1. Ka wehewehe a me ka haku mele ʻana o ka enamel

ʻO ka enamel kahi mea i hana ʻia e ka hoʻoheheʻe ʻana i nā mea aniani inorganic ma luna o kahi matrix metala a hoʻopaʻa ʻia i nā wela kiʻekiʻe.ʻO nā mea nui e pili ana i ka glaze (silicate, borate, etc.), colorants, fluxes, a me nā mea hoʻoikaika.I waena o lākou, ʻo glaze ke kumu no ka hoʻokumu ʻana i ka papa enamel, ka mea e hoʻoholo ai i nā waiwai kino a me nā kemika o ka enamel;Hoʻohana ʻia nā kala e hoʻohui i nā kala;Kōkua ʻo Flux i ka holo ʻana o ka glaze i ka wā o ke kaʻina hana, e hōʻoia i ka ʻili o ka glaze maʻemaʻe;Hoʻonui nā mea hoʻonui i ka ikaika mechanical a me ka pili o ka uhi.

2. Hoʻomākaukau i nā mea maka

ʻO ka hana mua i ka hana enamel ke koho a me ka hoʻomaʻamaʻa mua ʻana i nā mea maka.Hana ʻia ka substrate metala i ka hao, ke kila, ka aluminika, a me nā mea ʻē aʻe, a pono e koho ʻia nā mea kūpono a me ka mānoanoa e like me nā koi noi.ʻO ka hoʻomākaukau ʻana o ka glaze e hoʻohui i nā ʻano mea maka i ka like, e wili iā lākou i kahi ʻano o ka maikaʻi, e hōʻoia i ka like a me ka maikaʻi o ka uhi hope.I kēia manawa, koi ʻia ka hoʻāʻo ʻana i nā mea maka e hōʻoia i ka ʻole o nā haumia, i ʻole e hoʻopilikia i ka maikaʻi a me ka hana o ka papa enamel.

3. Ka lapaʻau ʻili

Ma mua o ka uhi ʻana, pono e hoʻomaʻemaʻe ʻia ka substrate metala a mālama ʻia ka ʻili e wehe i ka momona, ka ʻili oxide, a me nā mea haumia ʻē aʻe.ʻO nā ʻano hana maʻamau ka degreasing, ka holoi ʻana i ka waika, ka phosphating, a me nā mea ʻē aʻe.

4. Kaʻina hana enameling

Hiki ke hoʻokaʻawale ʻia ke kaʻina hana uhi i ʻelua mau ʻano: ke ʻano maloʻo a me ke ʻano pulu.ʻO nā ʻano hana maloʻo ka mea nui i ka hoʻopuʻi ʻana i ka pauka electrostatic a me ka uhi ʻana o ka moena i hoʻoheheʻe ʻia, i kūpono no ka hana automate nui, hiki ke hoʻopaʻa pono i ka mānoanoa o ka uhi ʻana, a me ke aloha kaiapuni.ʻO ke ʻano pulu ʻo ia ka uhi ʻōwili, ka uhi ʻana, a me ka uhi ʻana i ka pulupulu, ʻoi aku ka maikaʻi no nā ʻano paʻakikī a me nā hana liʻiliʻi liʻiliʻi, akā pili i ka pollution kaiapuni a me nā pilikia uhi ʻole.

5. Ke ahi

Pono e puhi ʻia ka huahana i uhi ʻia i ka wela kiʻekiʻe, ʻo ia kahi hana nui i ka hana ʻana i kahi papa enamel kiʻekiʻe.ʻO ka mahana ahi ma waena o 800 ° C a me 900 ° C, ma muli o ke ʻano glaze a me ke ʻano substrate.I ke kaʻina hana kī, heheʻe ka glaze a uhi pono i ka ʻili metala.Ma hope o ka hoʻoluʻu ʻana, hana ia i kahi papa enamel paʻakikī a maʻalahi.Pono nō hoʻi kēia kaʻina hana i ka mālama pono ʻana i ka nui o ka wela, ka manawa insulation, a me ka wikiwiki o ka hoʻomaha ʻana e pale ai i ka hiki ʻana mai o nā hemahema e like me nā māwae a me nā ʻōpū.

6. Nānā maikaʻi a me ka hana hope

Ma hope o ke kī ʻana, pono nā huahana enamel e nānā i ka maikaʻi o ka nānā ʻana, me ka nānā ʻana i nā hiʻohiʻona, ka hoʻāʻo ʻana i ka corrosion resistance, ka hoʻāʻo ʻana i ka ikaika mechanical, a me nā mea ʻē aʻe.Eia kekahi, ma muli o ka hoʻohana ʻana o ka huahana, pono paha nā hana hou aʻe e like me ka hui ʻana a me ka hoʻopili ʻana.

7. kahua noi

Ua hoʻohana nui ʻia ʻo enamel ma nā ʻano he nui ma muli o kāna hana maikaʻi loa.I loko o ka ʻoihana mea hana hale, e like me nā umu, nā mīkini holoi, nā mea hoʻomehana wai, a me nā mea ʻē aʻe, ʻaʻole ʻoluʻolu wale ka enamel liner a maʻalahi hoʻi e hoʻomaʻemaʻe, akā kūʻē i nā wela kiʻekiʻe a me ka corrosion.I loko o ka hale hoʻonaninani, hoʻohana mau ʻia nā papa kila enamel no nā paia o waho, nā tunnels, nā kahua kaʻaahi, a me nā mea ʻē aʻe ma muli o ko lākou mau kala momona a me ke kūpaʻa ikaika o ka wā.Eia kekahi, hoʻohana nui nā lāʻau lapaʻau, nā mea kemika a me nā māla ʻē aʻe i nā huahana enamel, e hoʻohana pono ana i kā lākou kūpaʻa kemika maikaʻi a me nā ʻano disinfection maʻalahi.

Ka hopena

ʻO ka holoʻokoʻa, ʻo ka hana ʻana i ka ʻoihana enamel kahi hana paʻakikī e hoʻohui i nā ʻenehana kuʻuna me ka ʻenehana hou.ʻO kāna mau huahana i hoʻopau ʻia ʻaʻole wale e hōʻike i ka hui maikaʻi loa o ka aesthetics a me ka pono, akā e hōʻike pū ana hoʻi i ka holomua o ka ʻepekema waiwai a me ka ʻenehana hana.Me ka hoʻomau mau ʻana o ka ʻenehana, ke neʻe nei nā huahana enamel i kahi ala ʻoi aku ka maikaʻi o ke kaiapuni, kūpono, a me ka multifunctional, e hoʻokō mau ana i nā pono o nā kahua like ʻole.

ʻO nā nīnau no ka Casting, Forging a i ʻole nā ​​ʻāpana mīkini, e ʻoluʻolu e kelepona iā mākou i kēlā me kēia manawa.
