He aha ka ʻokoʻa ma waena o ka Polyurethane a me ka Epoxy Resin?

1. ʻO ka maʻamau a me ka ʻokoʻa ma waena o ka Polyurethane a me ka Epoxy Resin:

ʻO ka hui like:

1) ʻO ka polyurethane a me ka resin epoxy he ʻelua mau mea, a ʻo nā mea hana a me nā ʻano hana like ʻole;

2) Loaʻa i nā mea ʻelua ke kūpaʻa tensile maikaʻi, ʻaʻohe haki, ʻaʻohe hāʻule a me nā waiwai ʻē aʻe;

3) Loaʻa iā lāua nā waiwai o ka corrosion resistance i ka waikawa ikaika, ka alkali, ka paʻakai a me nā mea aila like ʻole;

4) Loaʻa iā lāua ʻelua nā waiwai o ka lepo lepo, wai ʻole, ka pale ʻana i ka ʻili o ka ʻili, ke kūpaʻa koʻikoʻi koʻikoʻi, ka pale ʻana i ka hopena a pēlā aku;

Ka ʻokoʻa:

1) ʻO ka Polyurethane (PU) he polyphenylene diisocyanate a me ka polyether polyol.Hoʻopili ʻia a hoʻōla ʻia ma ke alo o ka catalyst triethylene diamine e hana i ka polymer kiʻekiʻe.Hoʻohālikelike ʻia me ka resin epoxy, ʻoi aku ka ʻona.

Loaʻa i ka Polyurethane nā hiʻohiʻona o ka adhesion maikaʻi, ka insulation a me ka pale ʻana i ka wā.Hiki ke hoʻololi ʻia ka paʻakikī ma ka hoʻoponopono ʻana i ka ʻike o ka diisocyanate a me ka polyether polyol, a hiki ke hoʻohana ʻia i loko o ka paʻi ʻana o nā mea uila a me nā lako uila.

2) Epoxy resin ka mea maʻamau i ka bisphenol A epoxy resin, curing agent (amine or acid anhydride), auxiliary agent, filler, etc. He lōʻihi kona manawa ho'ōla ma ka lumi wela a hiki ke ho'ōlaʻia e ka wela.Ma hope o ka mālama ʻana, loaʻa iā ia ka ikaika paʻa kiʻekiʻe a me ka paʻakikī.ʻO ka mea maʻamau, ʻano nui a hiki ke hoʻomālamalama ʻia e hoʻopili i nā modula uila a me nā diodes.

ʻOi aku ka maikaʻi o ka polyurethane i ke kū kūʻē ʻana i ka wā, ʻaʻole māha i nā mahana kiʻekiʻe a haʻahaʻa, a ʻoi aku ka pipiʻi.

2. ka hoʻohana ʻana i ka polyurethane a me ka epoxy resin:

1) Polyurethane resin:

ʻO ka polyurethane resin he mea polymer me ka ikaika kiʻekiʻe, ke kū'ē i ka waimaka, ka pale lole a me nāʻano'ē aʻe;

Hoʻohana ʻia e like mewiliwili,nā kāʻei lawe, hoses, ʻāpana kaʻa,kapu kamaa, ka ʻili synthetic, nā uwea a me nā uwea a me nā mea hana kino kino, etc.;

No ka hana ʻana i nā huahana plastik, ʻaʻahu i nā huahana synthetic synthetic, nā fibers synthetic, nā huahana foam paʻa a maʻalahi, nā adhesives a me nā uhi, etc.;

Hoʻohana ʻia ia no ka hoʻopau ʻana i ka ʻili o nā mea lāʻau like ʻole, nā mea kemika, nā lako kelepona a me nā mea kani a me nā ʻano o ka halihali.

2)Epoxy resin: hiki ke hoʻohana ʻia i nā uhi, nā mea hoʻopili, nā mea hoʻohui, etc.

ʻO ka epoxy resin coating kahi ʻano o ka papahele kiʻekiʻe, ʻaʻahu-kū a me ka nani, nona nā mea maikaʻi o ka seamless, ʻano paʻa paʻa, ke kūpaʻa kino maikaʻi, anti-corrosion, lepo-hōʻoia, mālama kūpono a me ka uku mālama haʻahaʻa.

Hiki ke hoʻolālā ʻia nā ʻano hoʻolālā like ʻole e like me nā koi o ka mea kūʻai aku, e like me ka uhi ʻana i ka lahilahi, 1-5mm mānoanoa iho-leveling papahele, anti-skid a paʻa i ka papahele, mortar floor, anti-static, anti-corrosion floor, etc.

He kūpono nā huahana no nā wahi like ʻole, e like me nā hale hana, nā lumi kamepiula, nā hale kūʻai, nā hale hana, nā papa, nā lumi hana, nā papa hana, etc.

3. ʻO ka topcoat mua i kūpono no ka hoʻohana ʻana i waho, aʻo ka mea hope e kūpono no ka hoʻohana ʻana i loko;

ʻO ka nāwaliwali nui a i ʻole ka pōʻino o ka mea hope, ʻo ia ka makaʻu i ka radiation ultraviolet ikaika, a huli ia i ka melemele ma lalo o ka radiation ultraviolet ikaika, ʻo ia hoʻi, mae, akā ʻaʻole ia e decompose a ʻaʻole e pili i ka hoʻohana ʻana;

Eia nō naʻe, ʻoi aku ka maikaʻi o ka mea mua i ka pale ʻana i ke aniau ma mua o ka hope, ʻoi aku ka lōʻihi o ka manawa melemele o ka mua ma mua o ka hope, no laila hoʻohana pinepine ʻia ka mea mua no nā koi kūkulu waho.
