Ke koi nui nei ka mākeke a me ka loaʻa kālā kiʻekiʻe i ka ulu wikiwiki ʻana o ka ʻoihana liʻiliʻi hale liʻiliʻi, ua hana nā laina hana i loko o ka kuke laiki, ka mea kuke induction, ka pā palai uila, ka lauoho lauoho a me ka ipu uila, ua lilo nā mea pono hale liʻiliʻi i mea e pono ai nā ʻohana o kēia lā.ʻO ka hapa nui o nā mea hana hale liʻiliʻi e hana ana i ke kaiapuni kiʻekiʻe, i mea e pale maikaʻi ai i kāna mau ʻāpana hana like ʻole, hoʻopuka pū ka uhi i ka hana kumu o ka wela kiʻekiʻe a me ka pale ʻana.I ka manawa like ʻoi aku ka maikaʻi o ka hoʻonaninani a me nā hana ʻē aʻe e hiki ke hoʻokō maikaʻi i ka noi mākeke.
Hoʻokahi, ka uhi silicone
ʻO ka uhi silikoni kekahi o nā mea uhi mua loa a hoʻohana nui ʻia i ka wela wela no nā mea pono hale liʻiliʻi ma Kina.ʻO ka uhi silikoni ka mea nui i haku ʻia me ka resin silicone ma ke ʻano he mea nui, hōʻike ka resin silicone i kahi ʻōnaehana paʻakikī paʻakikī, nā waiwai paʻa paʻa, ke kūpaʻa wela kiʻekiʻe.ʻO ka mahana hana o nā mea liʻiliʻi liʻiliʻi liʻiliʻi ma lalo o 300 ℃, a ʻo ke kiʻekiʻe kiʻekiʻe o ka pale ʻana o ka silicone coating hiki ke piʻi i 300 ℃.Mai ka hiʻohiʻona o ka hoʻokō ʻana i ka mahana, ʻo ka silicone coating he mea kūpono loa i ka uhi wela kiʻekiʻe no nā mea pono hale liʻiliʻi.
I mea e hoʻokō ai i nā pono o kahi liʻiliʻi liʻiliʻi hale hana wela ma luna o 300 ℃, nā mea hana pena i ka hoʻololi ʻana i ka hoʻololi ʻana o ka silicon coating, ʻo ke kumu kumu o ka hoʻololi ʻana ʻo ka hōʻemi ʻana i nā mea ʻaʻole kiʻekiʻe e like me ka hydroxyl content, hoʻonui i ka Si - O - ʻO nā kī a me ka hapa o nā ʻāpana inorganic kūʻokoʻa kiʻekiʻe, i hui pū ʻia me ka ʻenehana hoʻoili waiwai composite hou, Ua hoʻomaikaʻi maikaʻi ʻia ke kūpaʻa wela kiʻekiʻe o ka uhi silicone, a hiki i 600 ℃.
ʻAʻole maikaʻi ka pale ʻana o ka silicone coating wale nō, akā he ikaika ka adhesion, kiʻekiʻe ka paʻakikī o ka uhi ʻana, ka hana maʻalahi a me ke kumu kūʻai haʻahaʻa.ʻO kēia mau mea maikaʻi e hoʻomālamalama i ka uhi silicone i loko o ka mākeke mīkini hale liʻiliʻi a makemake ʻia e nā ʻoihana liʻiliʻi hale.Akā ʻike ʻia nā hemahema o ka uhi silicone, ka mea nui ma nā ʻano aʻe:
(1) ʻano hoʻihoʻi hope.Hoʻoikaika ʻia ka uhi i hoʻomākaukau ʻia e ka uhi silicone i ka molecular thermal motion i ka wela kiʻekiʻe, a e palupalu ke ʻano.I ka hoʻopili ʻana me nā mea ʻoi, ʻoi aku ka maikaʻi o ka uhi silicone i hoʻopili ʻia i ka ʻili o nā mea hale liʻiliʻi i nā ʻōpala a me nā pōʻino ʻē aʻe i ke ʻano o ka uhi.
(2) Pilikia palekana.Aia kekahi mau mea ʻawaʻawa i loko o ka uhi silicone, e laha mālie ʻia mai loko a i ka ʻili ma o ka infiltration, ʻoi aku ka hoʻopili pololei ʻana me ka meaʻai, aia paha nā pōʻino palekana meaʻai;
(3) Kūleʻa wela kiʻekiʻe loa.Me ka hoʻomaikaʻi hou ʻana i ka mahana o ka hoʻohana ʻana o kekahi mau mea hana hale, hiki i ka mahana hana o nā mea hale liʻiliʻi a hiki i 600 ℃, pehea e hoʻomaikaʻi hou ai i ka hoʻohana ʻana o ka uhi silicone ua lilo i pilikia koʻikoʻi e hoʻoponopono ʻia.I kēia manawa, ke alakaʻi nei kahi helu liʻiliʻi o nā mea hana uhi silicone nui me ka ikaika r&d i ka noiʻi kūpono a ua holomua kekahi, akā aia kahi ala lōʻihi e hele ai mai ka hoʻohana pono ʻana.
ʻElua, ka uhi fluorocarbon
ʻO ka uhi ʻana o Fluorocarbon, ma ke ʻano he mea hou, ʻaʻole i hoʻohana ʻia no ka manawa lōʻihi ma ka home a me nā ʻāina ʻē, akā ua hopohopo nui ʻia kona kūpaʻa kiʻekiʻe kiʻekiʻe, ke kūpaʻa corrosion ikaika, hoʻomaʻemaʻe ponoʻī, adhesion ikaika a me ka super weather resistance.ʻO ka uhi ʻana o Fluorocarbon ka mea nui o ka resin fluorine, paʻa loa kona mau mea kemika, kūpaʻa maikaʻi loa i ka wela wela.Hiki ke hoʻohana mau ʻia nā mea hana hale liʻiliʻi i uhi ʻia me ka uhi fluorocarbon i ke kaiapuni o 260 ℃ me ka ʻole o ka loli, a ʻaʻole hiki ke hoʻololi ʻia ka uhi fluorocarbon i ka aila, ʻaʻole e pane me ka meaʻai, palekana maikaʻi.ʻIke ʻia nā mea maikaʻi o ka uhi fluorocarbon, akā ʻike nui ʻia nā hemahema.Hōʻike nui ʻia kona mau hemahema i kona kūpaʻa wela ponoʻī, paʻakikī a me ke kūkulu ʻana i ʻekolu mau ʻano.ʻO ka paʻakikī o ka uhi ʻana o ka fluorocarbon i ka mahana maʻamau he 2-3h wale nō, ʻo ia hoʻi, ʻo ka uhi ʻana o ka fluorocarbon i ka mahana maʻamau ʻaʻole pono i kahi koʻi, kila uea pulupulu, a i ʻole me nā manamana lima hiki ke ʻoki ʻia ka uhi fluorocarbon, e like me ka uhi fluorocarbon. hoʻohana ʻia i nā hao uila e hālāwai me nā pihi a me nā mea ʻoi ʻē aʻe e ʻike pinepine ʻia nā mea ʻino i ka uhi ʻana.Hiki ke hana paʻa nā uhi Fluorocarbon i kahi kaiapuni o 260 ℃, a e hoʻoheheʻe ʻia ke kiʻekiʻe ka mahana ma mua o kēia.ʻO ka paʻakikī haʻahaʻa o ka uhi fluorocarbon e hoʻoholo i ka paʻakikī o ka uhi fluorocarbon i ke kūkulu ʻana a me nā kūlana ʻenehana.Pehea e mālama ai i ka hoʻopili ʻana a me ka maʻalahi o ka uhi fluorocarbon i ke kaʻina hoʻopaʻa ʻana he mea nui loa.Aʻoaʻo hoʻomohala e hiki mai ana o ka uhi fluorocarbon kiʻekiʻe:
(1) E hoʻoholo i ke kūpaʻa wela kiʻekiʻe o ka solvent i kēia manawa, ka paʻakikī a me nā kūlana hana paʻakikī a me nā pilikia ʻē aʻe;
(2) pale kaiapuni ʻōmaʻomaʻo ka uhi ʻana i ka fluorocarbon ma muli o ka wai;
(3) Composite o nā nanomaterials a me nā fluorocarbon coatings e hoʻomaikaʻi i ka nui o ka uhi a me nā waiwai ʻē aʻe.
ʻEkolu, uhi pauda
Ua ʻike nui ʻia ka uhi ʻana o ka pauka ma ke ʻano he "Efficiency, deep, Ecology and Economy" ma muli o ko lākou pono ʻole o ka solvent organik, ʻaʻohe pollution, kiʻekiʻe o ka hoʻohana ʻana a me ka haʻahaʻa haʻahaʻa o ka ikehu.Hiki ke hoʻokaʻawale ʻia ka pauka pauka i nā ʻāpana thermoplastic pauka a me ka thermosetting powder coatings e like me nā mea hana kiʻiʻoniʻoni like ʻole.ʻO ka mea maʻamau ka mea hoʻohana hale liʻiliʻi ʻo ka uhi ʻana i ka pauka paʻa wela, ʻo kāna kumu nui ka hoʻohana ʻana i ka resin me ka liʻiliʻi molekala kaumaha a me ka lāʻau lapaʻau e hoʻohua ai i ka hoʻohui ʻana i ke ala e hana ai i ka uhi macromolecule reticulate i ka hana wela kiʻekiʻe.Ma ke kahua o nā mea hana hale liʻiliʻi, ʻoi aku ka nui o ka hoʻohana ʻana i ka pauka polyester, ka uhi ʻana i ka pauka acrylic, ka epoxy pauka a me ka polyurethane pauka.Ua ulu wikiwiki ka pauka i nā makahiki i hala iho nei, me nā ʻano like ʻole a ʻoi aku ka maikaʻi o ka hana.He kiʻekiʻe loa ke kumukūʻai o ka uhi pauda no nā lako hale liʻiliʻi me ke kumu kūʻai haʻahaʻa.Manaʻolana ʻia e hiki i nā mea hana uhi ke hoʻomohala i ke kumu kūʻai haʻahaʻa a me ka hana kiʻekiʻe o ka pauka i kūpono no nā mea pono hale liʻiliʻi.
Ua ʻike ʻia ka uhi hoʻōla ʻana o Ultraviolet (UV) ma ka mākeke i kēia manawa, ʻo kāna kumu nui ka hoʻohana ʻana i ke kukui ultraviolet e hoʻoulu i ka photoinitiator e hana i ka resin photosensitive unsaturated kī hui cross-linking reaction e hana i ke ʻano o ka uhi.ʻOiai he maʻalahi ke kaʻina hana o ka uV-curable coating, he kumukūʻai a ʻaʻole kūpono ke kūpaʻa wela o ka uhi, no laila ʻaʻole hiki ke hoʻohana nui ʻia i ka hana ʻana i nā mea pono hale liʻiliʻi.
