Nano Silica Powder no ka Epoxy Coating E hoʻohana i ka SiO2 Nanoparticle

ʻO ka wehewehe pōkole:

Nano Silica Powder no ka Epoxy Coating Hoʻohana hiki ke hoʻokō i nā waiwai o ka anti-corrosion, hoʻonui, hoʻomaikaʻi i ka permeability a me ka hoʻopili ʻana o ka uhi.Loaʻa i ka SiO2 Nanoparticle ka nui liʻiliʻi a me ka hana maikaʻi loa ma nā ʻano he nui.Loaʻa ka hydrophilic a me ka hydrophobic silicon dioxide nano pauka no nā kumu like ʻole.

wehewehe:

1. No kona liʻiliʻi liʻiliʻi, hiki iā SiO2 nanopowder ke hoʻopiha pono i nā micro-cracks a me nā pores i hana ʻia e ka shrinkage kūloko i ka wā o ka hoʻōla ʻana o ka resin epoxy, e hoʻemi i ke ala diffusion o nā media corrosive, a hoʻonui i ka hana pale a me ka pale o ka uhi;

2. No kona paʻakikī kiʻekiʻe, hoʻonui ka silica nanoparticle i ka paʻakikī o ka resin epoxy, a laila e hoʻonui ai i nā waiwai mechanical.
Eia kekahi, hiki i ka hoʻohui ʻana i ka nui kūpono o nā ʻāpana nano silicon oxide hiki ke hoʻonui i ka ikaika paʻa o ka epoxy coating a hoʻonui i ke ola lawelawe o ka uhi.

ʻO ka Nano silica kahi mea non-metallic inorganic me ka wela maikaʻi a me ke kūpaʻa ʻana.ʻO kona mokuʻāina molekala he ʻano pūnaewele ʻekolu-dimensional me [SiO4] tetrahedron ma ke ʻano he kumu kumu.I waena o lākou, pili pono ka oxygen a me ka silicon atoms e nā covalent bonds, a ikaika ka hale, no laila he mau waiwai kemika paʻa, maikaʻi ka wela a me ka pale ʻana i ka wā, etc.

Hoʻokani nui ʻo Nano silicon dioxide i ka hana o ka anti-corrosion filler i ka epoxy coating.Ma ka lima hoʻokahi, hiki i ka nano SiO2 ke hoʻopiha pono i nā micro-cracks a me nā pores i hana ʻia i ke kaʻina hana hoʻōla o ka resin epoxy, a hoʻomaikaʻi i ke kūpaʻa ʻana;ma ka ʻaoʻao ʻē aʻe, hiki i nā hui hana o ka nano silica a me ka epoxy resin ke hoʻokumu i nā wahi pili kino / kemika ma o ka adsorption a i ʻole ka pane ʻana, a hoʻokomo i nā paʻa Si-O-Si a me Si-O-C i loko o ke kaulahao mole e hana i ʻekolu. -ka hoʻolālā pūnaewele dimensional e hoʻomaikaʻi i ka pili ʻana o ka uhi.Eia kekahi, hiki i ka paʻakikī kiʻekiʻe o ka nano SiO2 ke hoʻoikaika nui i ka pale ʻana o ka uhi, a laila e hoʻolōʻihi i ke ola lawelawe o ka uhi.
