ʻO Alkyd kekahi ʻano pena loaʻa i ka resin polyester a hoʻololi ʻia me nā waikawa momona, i loaʻa mai nā polyols, nā ʻakika organik, a me nā triglycerides. He ʻano pena ʻaila ʻokoʻa kona ʻano mai nā ʻano pena ʻē aʻe.
Ua like ka pena Alkyd me ka pena enamel, akā me ke ʻano ʻokoʻa a me ka manaʻo. He koho maikaʻi loa ia no ka pena ʻana i nā paia a hāʻawi i kahi hopena maikaʻi loa e maʻalahi ke wehe i ka wā e pono ai.
Na kēia alakaʻi e haʻi iā ʻoe i nā mea āpau e pono ai ʻoe e ʻike e pili ana i ka pena alkyd, mai ke ʻano o ka hoʻohana ʻana.
Ma kēia pou e uhi mākou:
Alkyd: ʻO ke kī i ka hoʻopau maikaʻi ʻana ma kou pā hale
ʻO Alkyd kahi huaʻōlelo e hōʻike ana i kahi ʻano pena i loaʻa kahi resin polyester i hoʻololi ʻia e ka hoʻohui ʻana i nā ʻakika momona a me nā mea ʻē aʻe. Loaʻa ʻia nā Alkyds mai nā polyols a me nā ʻakika organik, me nā ʻakika dicarboxylic a i ʻole carboxylic acid anhydride a me nā aila triglyceride. Hoʻohana mau ʻia ka huaʻōlelo "alkyd" i ka ʻoihana pena e wehewehe i kahi ʻano pena i hoʻopaʻa ʻia i ka ʻaila i ʻokoʻa ka hana ma mua o nā ʻano pena ʻē aʻe.
Pehea i hana ʻia ai ka pena Alkyd?
Ua like ke kaʻina hana no ka pena alkyd me nā ʻano pena ʻē aʻe. Eia nō naʻe, ʻoi aku ka nui o ka ʻaila a me ka resin i ka pena alkyd ma mua o nā ʻano pena ʻē aʻe. ʻO ka hoʻohui ʻana i kēia mau mea e hoʻoikaika i ka maʻalahi a me ka paʻa ʻana i ka huahana hope, e hopena i kahi ʻili paʻakikī ke pena ʻia ma nā paia.
He aha nā ʻano like ʻole o ka pena Alkyd?
Nui nā ʻano pena alkyd i loaʻa, ʻo kēlā me kēia me kona ʻano ponoʻī a me nā pono ponoʻī. ʻO kekahi o nā ʻano pena alkyd i ʻike pinepine ʻia:
- Pena Alkyd Enamel: He mea maikaʻi kēia ʻano pena alkyd no ka hoʻohana ʻana ma nā ʻili metala ma muli o kona paʻa paʻa a paʻa.
- ʻO ka pena alkyd hybrid: ʻO kēia ʻano pena alkyd he hui pū ʻana o ka pena alkyd a me ka pena latex, e lilo ia i mea koho maikaʻi loa no ka poʻe makemake i nā pono o nā ʻano pena ʻelua.
- ʻO ka pena alkyd i hoʻopaʻa ʻia i ka aila: Hoʻohana mau ʻia kēia ʻano pena alkyd no ka pena ʻana i nā paia o ka hale, no ka mea, hāʻawi ia i kahi hopena maikaʻi loa a maʻalahi ke wehe inā pono.
Pehea e hoʻoholo ai inā kūpono ka pena Alkyd iā ʻoe?
Inā makemake ʻoe i ka hoʻopau maikaʻi ʻana ma nā paia o kou home a makemake ʻoe e kali lōʻihi no ka maloʻo ʻana o ka pena, ʻo ka pena alkyd paha ke koho kūpono iā ʻoe. E noʻonoʻo i kēia mau mea i ka wā e hoʻoholo ai inā kūpono ka pena alkyd no kāu mau pono pena.
- Makemake ʻoe i kahi ʻili paʻakikī ma kou mau paia?
- Makemake ʻoe e pena i nā ʻili metala?
- Makemake ʻoe i kahi pena i maʻalahi e hoʻopili a hāʻawi i kahi hoʻopau kūlike?
- Makemake ʻoe e kali lōʻihi no ka maloʻo ʻana o ka pena?
- Makemake ʻoe i kahi pena maʻalahi ke wehe inā pono?
ʻIke ʻana i nā mea kupanaha o ka pena Alkyd: He alakaʻi alakaʻi no ka ʻoihana
He mau hiʻohiʻona kūʻokoʻa ka pena Alkyd mai nā ʻano pena ʻē aʻe, e like me:
- Hoʻopau maʻemaʻe: Loaʻa i ka pena Alkyd kahi hoʻopau maʻemaʻe a ʻālohilohi ʻaʻole like me nā ʻano pena ʻē aʻe.
- Ka uhi: Hiki i ka pena Alkyd ke uhi i nā ʻili i loko o hoʻokahi a ʻelua paha ʻaʻahu, e lilo ia i koho kaulana no nā mea pena kiʻi.
- Kūleʻa i ka wai a me nā mea kemika: Paʻa loa ka pena Alkyd i ka wai a me ka pōʻino kemika, kūpono ia no ka hoʻohana ʻana i nā wahi i ʻike ʻia i nā kūlana paʻakikī.
- ʻO nā puaʻa i hoʻopaʻa ʻia: Hoʻokuʻu ʻia nā puaʻa i ka pena alkyd i loko o ka resin, e hiki ai ke hoʻopaʻa ʻia ka waihoʻoluʻu maikaʻi aʻe.
- Hoʻohana palaki: Hiki ke hoʻopili ʻia ka pena Alkyd me kahi pulupulu, e maʻalahi ka hoʻohana ʻana no nā poʻe loea a me nā mea hoihoi DIY.
Pehea ka hoʻohālikelike ʻana o ka pena Alkyd me nā pena ʻē aʻe?
Hoʻohālikelike pinepine ʻia ka pena Alkyd me nā pena acrylic a me ka ʻaila. Eia kekahi mau ʻokoʻa nui:
- Acrylics: ʻOi aku ka maloʻo o ka pena ʻālika ma mua o nā pena alkyd a ʻoi aku ka maʻalahi o ka hoʻomaʻemaʻe ʻana me ka wai. Akā naʻe, ʻaʻole lōʻihi lākou e like me nā pena alkyd a ʻaʻole like ka pae o ka glossiness.
- ʻAila: ʻOi aku ka lōʻihi o ka maloʻo ʻana o nā pena aila ma mua o nā pena alkyd a makemake i nā mea hoʻoheheʻe no ka hoʻomaʻemaʻe. He melemele nō hoʻi lākou i ka wā. Eia nō naʻe, ʻoi aku ka maʻalahi o ka hoʻopau ʻana a ʻoi aku ka maʻalahi ma mua o nā pena alkyd.
Ka hoʻomaopopo ʻana i nā ʻano uhi like ʻole o nā Alkyds
Loaʻa i nā alkyd ʻaila lōʻihi ka nui o ka aila, ʻoi aku ma mua o 60%. Pono lākou i kahi manawa maloʻo lōʻihi akā hana i kahi hoʻopau paʻakikī a maʻalahi. Hoʻohana maʻamau ʻia lākou i loko o nā pena paʻi meaʻai a me nā uhi.
Aila Alkyds
Loaʻa i nā alkyds ʻaila ʻaila ka ʻaila mai 40% a 60%. Maʻalahi lākou e hoʻopili a hana i kahi hopena maikaʻi. Hoʻohana pinepine ʻia lākou i ka hana ʻana i nā kini uila a no ka hana maʻamau hūpono.
Nā Alkyd i hoʻololi ʻia
ʻO nā alkyd i hoʻololi ʻia he alkyds i hoʻololi ʻia me nā mea ʻē aʻe e hoʻomaikaʻi i kā lākou hana. ʻO kekahi o nā hoʻololi maʻamau e pili ana i nā phenolics, bisphenol A, a me nā monomers acrylic. Hoʻololi nā hoʻololi i ka manawa maloʻo, adhesion, kū'ē kemika, a me ka pale wela o ka uhi.
Alkyd Hybrids: ʻO ka hui maikaʻi o nā resins
ʻO Alkyd hybrids he hui pū ʻana o ka alkyd a me nā resins ʻē aʻe, e like me ka epoxy, polyester, a i ʻole nā resins wai. Hoʻokumu ʻia kēia mau hybrids e ka hui ʻana i ka alkyd me nā precursors resin epoxy unreacted ma mua o ka hoʻōla ʻana. ʻO ka hopena he uhi kūikawā e hoʻohui i nā waiwai maikaʻi loa o kēlā me kēia resin.
ʻAno Alkyd Hybrids
Aia kekahi mau ʻano o nā alkyd hybrids i loaʻa, me:
- Epoxy-alkyd hybrids: Hāʻawi kēia mau uhi i ka hoʻopili maikaʻi ʻana a me ka pale ʻana i ka corrosion, e hana maikaʻi ai lākou no ka hoʻohana ʻana ma nā ʻili metala.
- Nā polyester-alkyd hybrids: He lōʻihi loa kēia mau uhi a hāʻawi i ka paʻa ʻana o ka nani, e hana maikaʻi ia no ka hoʻohana ʻana ma nā ʻaoʻao o waho.
- ʻO nā hybrids alkyd wai: ʻO kēia mau mea uhi e pili ana i ka kaiapuni a hāʻawi i nā hoʻokuʻu haʻahaʻa VOC, e hoʻolilo iā lākou i mea kūpono no ka hoʻohana ʻana i nā wahi o loko.
- Nanocomposite alkyd hybrids: Aia i loko o kēia mau uhi nā nanoparticles e hoʻonui ai i nā waiwai o ka uhi, e like me ka pale ʻana a me ka pale UV.
Panina
No laila, ʻo ia ke ʻano o ka alkyd- he ʻano pena i hui pū ʻia me ka ʻaila, resin, a me ka wax. He mea maikaʻi ʻo Alkyd no ka pena ʻana i nā paia no ka mea hāʻawi ia i kahi hoʻopau maʻemaʻe a kūpaʻa i ka wai a me nā kemika. Hiki iā ʻoe ke hoʻohana iā ia ma luna o nā ʻili metala, e hoʻolilo iā ia i ʻano pena maʻamau. No laila, inā ʻoe e ʻimi nei i kahi paʻa paʻa a paʻa, ʻo ka pena alkyd ke ala e hele ai.
ʻO wau ʻo Joost Nusselder, ka mea nāna i hoʻokumu i ke Kauka Mea Hana, mea kūʻai maʻiʻo, a me ka makuakāne. Makemake au i ka hoʻāʻo ʻana i nā mea hana hou, a me kaʻu hui ua hana au i nā ʻatikala blog hohonu mai ka makahiki 2016 e kōkua i ka poʻe heluhelu kūpaʻa me nā mea hana a me nā ʻōlelo aʻoaʻo.
