Acrylic vs urethane conformal coating - He aha ka Polyurethane Conformal Coating?

ʻO nā uhi kuʻuna hoʻohana ʻia i nā papa kaapuni i paʻi ʻia e hoʻomaikaʻi i ka hilinaʻi a me ka lōʻihi o ka mea hana. Hoʻokumu kēia mau mea polymeric i kahi kiʻiʻoniʻoni e pale ana i ka uila mai nā mea hoʻoweliweli e like me ka corrosion, ka wai, a me ka haʻahaʻa. Aia nā ʻāpana conformal like ʻole, i waena o lākou epoxy, silicone, acrylic, parylene, a me polyurethane.

ʻO ka polyurethane conformal coating he papa pale paʻakikī i kū i ka abrasion a me nā mea hoʻoheheʻe. ʻO nā hiʻohiʻona o ka polyurethane pū kekahi

• ʻO kaʻaila a me ke kūpaʻa wai
• No laila hiki ke maʻalahi i nā ʻano like ʻole
• Hoʻohāpai ka helu wela; papa F kiko'ī
• ʻO ka viscosity ka mea hiki ke hoʻokō i ka lahilahi i makemake ʻia
• Hoʻopili uila hilinaʻi; paʻa ka insulation i kahi hoʻāʻo kaʻa kaʻa

Nā pōmaikaʻi

Hoʻonui ka polyurethane i ke ola o ka mīkini ma ka hoʻonui ʻana iā lākou. E hōʻoia i hiki iā lākou ke hana me ka hilinaʻi ʻole me ka nānā ʻole i nā kūlana.

He ikaika a paʻa hoʻi kēia uhi ʻana, e kūʻē i nā mea hoʻoheheʻe organik a me ka haʻahaʻa.

ʻO ka uhi paʻakikī ke pale aku i ka ʻaʻahu mechanical a hoʻēmi pū i ka ulu ʻana o ka ʻumi ʻumi.

Nā noi 

ʻOi aku ka maikaʻi o nā uhi polyurethane no nā mea uila e kū pono ana i ka hoʻolaha kemika. He maikaʻi lākou i ka mālama ʻana i nā mea hana, nā mea hoʻololi, nā kaʻa, a me nā relay, i waena o nā mea ʻē aʻe, i hoʻokaʻawale ʻia a pale ʻia.

Ua kaulana nō hoʻi ka uhi ʻana i ka aerospace a me nā kaʻa kaʻa. ʻO kona pale wela ka mea e pale ai i nā mea uila i loko o ka paʻakai paʻakai a me nā wahi kemika.

Ma ke koho ʻana i kēia hoʻopili conformal ʻano, maopopo ʻoe e holo pono kāu huahana uila a hiki i nā wahi paʻakikī. He haʻahaʻa ka polyurethane i ka friction a me ka pale ʻana i ka abrasion i hoʻohālikelike ʻia me nā mea conformal ʻē aʻe.

ʻO ke kaʻina hana uhi 

Loaʻa ka uhi ʻana o ka polyurethane conformal i loko o kahi hoʻolālā ʻelua a i ʻole hoʻokahi hui. ʻO ka palaki ʻana, ka pulupulu ʻana, a hiki iā ʻoe ke hoʻohana i nā ʻano hoʻopaʻa no ka hoʻopili ʻana i ka papa ma kahi e pono ai. Ma hope o ka noi, waiho ʻia ke kiʻiʻoniʻoni e hoʻōla loa no ka pau ʻana o ke kaʻina hana uhi; hoʻokahi hola a ʻelua mau lā e hoʻopau ai. ʻOiai ua maʻalahi ka hoʻohana ʻana i nā ʻāpana hoʻokahi, pono lākou i nā lā ma mua o ka hoʻopiha ʻana a mākaukau no ka hoʻohana.

Hiki ke hoʻoholo ʻia ke kaʻina hana noi e nā mahana i hana ʻia ai ka hana. ʻOi aku ka wikiwiki o ka hoʻōla ʻana o ka urethane ma nā wahi i hoʻokiʻekiʻe ʻia ka mahana. Hiki ke hoʻopili ʻia ke kaʻina hana me ka hoʻohana ʻana i ka wela a me ka ʻike UV; i kekahi manawa, ʻo ka hoʻomaʻamaʻa ʻana i ka makū he mea ʻē aʻe e hoʻohui i nā polymers.

ʻO nā hemahema 

He mea kupanaha ka uhi ʻana o ka polyurethane conformal ma ke ʻano o ka pale ʻana i ka makū, abrasion, a me ka haʻalulu wela. Eia nō naʻe, loaʻa iā ia ka hemahema o kahi kaʻina hoʻōla lōʻihi. Hiki ke lōʻihi ka manawa post-cure, a hiki ke hoʻopau i ka hoʻoholo ʻana i nā waiwai āu e hauʻoli ai i ka hopena. E huli melemele nō hoʻi nā ʻaʻahu i ko lākou mau makahiki; ʻaʻole ia he mea e pili ana i ko lākou hilinaʻi ʻana, akā ʻaʻole ia he mea nani.

Panina 

He mea koʻikoʻi ke koho ʻana i ka mea conformal kūpono no ka mea e hoʻoholo i nā pae palekana āu e hāʻawi ai i nā hāmeʻa ma ka lima. E ʻike i nā mea a pau e pono ai ʻoe e pili ana i nā koho pani i loaʻa a pili iā lākou i kāu mau pono pale uila. ʻO ka hoʻomaʻamaʻa ʻana iā ʻoe iho me nā drawbacks a me nā hemahema hiki ke hoʻokomo iā ʻoe i kahi kūlana maikaʻi aʻe e mālama i ke kaʻina hana uhi. No ka hōʻemi ʻana i ka manawa o ka hana hewa ʻana i ka noi a me ka mālama ʻana i nā kaʻina hana, hiki iā ʻoe ke ʻimi i nā lawelawe conformal coating mai nā hui hilinaʻi a me nā lawelawe lawelawe. ʻOi aku ka maikaʻi ma mua o ka lawe ʻana i kahi pilikia e hiki ke hōʻino i kāu uila a me kā lākou mau mea.

No ka ʻike hou aku e pili ana i ka uhi ʻana o ka acrylic vs urethane conformal - he aha ka polyurethane conformal coating, hiki iā ʻoe ke kipa i DeepMaterial ma https://www.epoxyadhesiveglue.com/what-is-polyurethane-conformal-coating-and-what-is-the-purpose-of-it/ no ka mea,ʻike'ē aʻe.
