Nā uhi wai vs. nā uhi hoʻoheheʻe

Lawe pinepine nā uhi i ko lākou inoa mai ka mea hoʻopaʻa, a i ʻole ka resin, kahi i hana ʻia ai lākou. ʻO nā epoxies, alkyds a me nā urethanes nā hiʻohiʻona o nā resins e hāʻawi ana i kahi uhi i ko lākou inoa. Akā, ʻaʻole kēia wale nō nā ʻāpana e hana ana i kahi uhi. Ma waho aʻe o nā mea hoʻohui, hiki ke hāʻawi i kahi uhi i kekahi mau waiwai hana, a me nā pigments e hāʻawi i ke kala, loaʻa pū i nā uhi kahi mea e hoʻoheheʻe i nā mea āpau i loko o kahi wai no ka hoʻopili maʻalahi.

ʻO ka maʻamau, lawe kēia mea hoʻoheheʻe i ke ʻano o ka wai a i ʻole kekahi mea hoʻoheheʻe kemika ʻē aʻe. No laila, ʻo nā huaʻōlelo "wai-based" a me "solvent-based". ʻO ke ʻano o ka huahana kūpono no ka hana e pili ana i nā kūlana. Ma ke ʻano laulā, ʻaʻole ʻoi aku ka maikaʻi o kekahi ma mua o kekahi, akā hana like ʻole lākou i nā kūlana like ʻole. ʻO ke kūpono, e noho pū nā koho ʻelua ma ka ʻaoʻao o ka mea hana a ka loea uhi.

Nā Uhi Wai

ʻO nā pena wai e hana ana ma kahi o 80 pakeneka o nā pena hale i kūʻai ʻia i kēia lā e like me ka Paint Quality Institute, kahi hui aʻoaʻo a hoʻāʻo pena. ʻAʻohe kānalua he hapa nui kēia ma muli o kekahi o nā mea hoihoi nui o nā huahana wai, inā he pena hale o loko a i ʻole ka uhi pale kaumaha: emi nā ʻala.

I ka wā e hana ana i nā wahi paʻa a i ʻole nā ​​wahi ea ʻole, hiki i ka mahu ʻana o nā mea hoʻoheheʻe ke lilo i mea ʻoluʻolu ʻole no nā limahana a i ʻole he mea weliweli loa i ko lākou olakino. No kēia kumu, nui nā papahana e like me nā mea e pili ana i nā pahu mālama wahie a me nā kaʻa pahu kaʻaahi e hoʻohana ana i nā uhi wai. Hoʻemi pū kēia i ka nui o nā mea lapalapa e hōʻiliʻili ana i loko o kahi paʻa. ʻAʻole naʻe ia manaʻo e hōʻole ka hoʻohana ʻana i nā uhi wai i ka pono noNā hana palekana no nā wahi paʻa i ʻāpono ʻia e OSHA.

ʻO ke kūlike o ke kaiapuni kekahi kumu maʻamau no ke koho ʻana e hoʻohana i kahi uhi wai. Hoʻoheheʻe ʻia ka nui o nā mea hoʻoheheʻe i loko o nā mea i ʻike ʻia he mau hui organik volatile, a i ʻole VOC. Hoʻoponopono pinepine nā aupuni aupuni, mokuʻāina a me ke kūloko i nā VOC ma ka kaupalena ʻana i ka nui o nā ʻoihana i ʻae ʻia e hoʻokuʻu i loko o kahi manawa i hāʻawi ʻia.Hoʻokumu ka EPA i nā lula aupunino nā VOC, akā ua hoʻopaʻa hou kekahi mau mokuʻāina i nā kapu, e pono ai nā hana i hui pū ʻia e kaupalena i kā lākou hoʻokuʻu ʻana.

ʻAʻole naʻe i loaʻa i nā uhi wai ka ʻole o nā mea hoʻoheheʻe. He nui nā mea i kapa ʻia he co-solvents, nā mea hoʻoheheʻe i loaʻa i nā ʻano haʻahaʻa a manaʻo ʻia e kōkua i ka hoʻokuke ʻana i ke koena o ka wai mai loko mai o ka uhi i ka wā e maloʻo ai. Akā, ʻoiai ʻaʻohe o nā mea hoʻoheheʻe o nā uhi wai, a i ʻole ka emi ʻana o nā mea hoʻoheheʻe, he ala maikaʻi loa ia e hoʻohaʻahaʻa ai i ka hana VOC o kahi ʻoihana. No kekahi mau ʻoihana, hiki i kēia ke ʻano o ka hoʻolilo ʻana i ka liʻiliʻi ma ke aʻo ʻana i ka mālama ʻana i ke kaiapuni. A i ʻole e pale iā lākou mai ka uku ʻana i nā uku nui no ka ʻoi aku ma mua o nā kuota VOC.

Nā Uhi Hoʻoheheʻe Wai

Hana ʻia nā pena i hoʻokumu ʻia i ka solvent me nā mea hoʻoheheʻe i manaʻo ʻia e hoʻomake ma o kahi hopena kemika me ka oxygen. ʻO ka maʻamau, ʻo ka neʻe ʻana o ka ea e hoʻopuni ana i kahi uhi i hoʻokumu ʻia i ka solvent e kōkua i ka wikiwiki o ka hopena, e hōʻemi ana i nā manawa maloʻo.

Loaʻa i kēia mau uhi kekahi pono nui ma mua o nā uhi wai. ʻAʻole lākou i maʻalahi i nā kūlana kaiapuni e like me ka mahana a me ka makū i ka wā hoʻōla. Hiki i ka makū ke pale i ka wai i loko o kahi uhi wai mai ka mahu ʻana, e lilo ai lākou i mea kūpono ʻole i kekahi mau aniau.

ʻO nā uhi wai e hōʻike ana i kahi pilikia i ka pae hoʻomākaukau ʻili o kahi papahana uhi. ʻO ka wai, ʻoiai he pani hoʻohiki no nā mea hoʻoheheʻe i kekahi mau kūlana, he ʻāpana koʻikoʻi nō hoʻi ia o ke kaʻina hana palaho, ke kumu holoʻokoʻa no ka ʻoihana uhi ʻoihana ma kahi mua. Inā pili ka wai me ka substrate ma mua o ka hoʻopili ʻia ʻana o ka uhi, hiki ke hoʻomaka ka popo ʻana. I mea e hōʻoia ai ʻaʻole kēia ka hihia, pono e hana ʻia nā uhi wai i hiki ke huki ʻia ka wai āpau ma o ka ʻili ʻili ma mua o ka hiki ʻana mai o ka palaho. ʻAʻole kēia he mea e noʻonoʻo ai me nā uhi solvent.

No laila, i ka hōʻuluʻulu manaʻo, ʻoiai he koho maikaʻi paha nā uhi wai no nā hana e pili ana i nā wahi paʻa a me ka hoʻohana mau ʻana i nā uhi, ʻaʻole lākou me ka ʻole o ko lākou mau wahi nāwaliwali. ʻO nā hana ma nā kūlana hāmama a pulu, e like me nā mea i loaʻa pinepine i nā papahana uhi hou ʻana o ke kahua, hiki nō ke pōmaikaʻi mai ka uhi kūpono. Inā makemake ʻoe e kūkākūkā i ke ʻano o ka huahana i kūpono loa no kāu papahana, makemake mākou e lohe mai iā ʻoe.E hoʻokaʻaʻike aku iā mit-ivy industry Coatingsi kēia lā. A i ʻole, inā makemake ʻoe e nānā mua i kā mākou laina huahana piha, e hoʻoiho i kā mākou papa inoa huahana ma lalo nei.
