He aha ke ʻano o ka hoʻomaʻamaʻa ʻana o ka pā 3d bending?

He aha ke ʻano lapaʻau maikaʻi no ka ʻili o ka3d piko pa? ʻO ka pīpī ʻana i ka plastic kahi ʻano hana lapaʻau maʻamau no nā pā hale kūʻai. ʻO ka pīpī ʻana i ka plastic, ka pollution ʻole i ke kaiapuni, non-toxic i ke kaiapuni, non-toxic i ke kino o ke kanaka, ʻoi aku ka maikaʻi o ka hiʻohiʻona o ka uhi ʻana, ka ikaika adhesion, ka ikaika mechanical kiʻekiʻe, ka manawa hoʻōla pōkole, ke kiʻekiʻe kiʻekiʻe a me ka uhi ʻana i ka lole, maʻalahi ke kūkulu ʻana, nā koi ʻenehana no nā limahana.
Hiki ke hoʻokaʻawale ʻia ka plastic impregnated i ʻelua mau mea maka, ka wai a me ka pauka. ʻOi aku ka nui o ka mānoanoa o ka uhi ʻana ma mua o ke kaʻina hana hoʻoheheʻe, a maikaʻi ke kūpaʻa corrosion. Hoʻohana pinepine ʻia no ka mālama ʻana i ka pā o waho o ka lumi.

ʻO ka galvanizing wela kahi ala maikaʻi o ka pale ʻana i ka ʻino metala. ʻO ia ka hoʻoheheʻe ʻana i ka hopena zinc i hoʻoheheʻe ʻia o ka ʻāpana kila ma hope o ka wehe ʻana i ka ʻōpala ma kahi o 500 degere Celsius, no laila aia ke ʻano kila a me ka papa zinc ma ka ʻili, no laila ke kumu o ka anti-corrosion. Loaʻa i ka Hot-dip galvanizing nā mea maikaʻi o ka uhi zinc mānoanoa, lōʻihi ka paʻakai paʻakai a me ka ikaika o ka corrosion. Hoʻohana nui ʻia ia i ka pale ʻana i ka corrosion o nā mea hana ʻoihana, e like me ka mālama ʻana o nā alahaka uwea, nā hale kiaʻi mana, a me nā alahaka kila. ʻOi aku ka kiʻekiʻe o ka pale ʻana o ka galvanizing wela ma mua o ka galvanizing anu.
Ua kapa ʻia ʻo Cold galvanizing. Hoʻohana ia i nā lako electrolysis e wehe i ka ʻaila, pickling, a laila hoʻokomo i loko o ka wai paʻakai zinc, a hoʻohui i ka electrode maikaʻi ʻole o nā mea hana electrolysis. Hoʻokomo ʻia ka pā zinc ma kekahi ʻaoʻao o ka paipu a pili i ka cathode o ka mea electrolysis. ʻO ka neʻe ʻana o kēia manawa mai ka electrode maikaʻi a i ka electrode maikaʻi ʻole e pohō i luna a i lalo i ka paipu. Hoʻokomo ʻia kahi papa o ka zinc, hoʻomaʻamaʻa ʻia ka paipu anu a hoʻopaʻa ʻia.
3d piko paʻO ke ʻano o ka hoʻomaʻamaʻa ʻana i ka ili ʻO kēia ʻano ka hoʻomaʻemaʻe alkaline, ka holoi wai maʻemaʻe, ka holoi ʻana i ka waikawa, ka holoi wai wela, ka cathode degreasing, kemika degreasing, ka hoʻoulu ʻana i ka wai a me nā kaʻina hana like ʻole.
