ʻO ke alakaʻi koho ʻana i ka wai puhi no ka hana ʻoi loa o ka mīkini noe 

ʻAʻole kikoʻī ke koho ʻana i ka wai uwahi kūpono - ʻo ia ka ʻokoʻa ma waena o ka ʻāʻī a me ka nozzle paʻa a me nā nozzles paʻa, ka hoʻopuka ʻole ʻana, a i ʻole ka pani ʻana i ka mīkini. Ua ʻike mua mākou iā ia: kahi mīkini noe kiʻekiʻe e hana hewa ana i ke kauwela haʻahaʻa o Shanghai-a hiki i ka wā i hoʻololi ai ka poʻe holo moku i kahi wai haʻahaʻa haʻahaʻa, ʻaʻole i hoʻāʻo ʻia. I loko o 90 mau minuke, ua hāʻule ka huahana e 60%. Ua hewa ke kumu wela. Ua ʻōhumu ka hui hanana. ʻAʻole i hoʻokaʻawale ʻia kēlā hanana. I loko o nā makahiki ʻelima i hala iho nei, hōʻike kā mākou mau loiloi kākoʻo ʻenehana i nā pilikia pili i ka wai no 73% o ka hana ʻana o ka mīkini noe ma ka pūnaewele i ka wā o ka punawai-a-fog i hoʻohui ʻia.

No ke aha e pili pono ai ke koho ʻana i ka wai uahi i ka manawa o ka mīkini noe

ʻAʻole hoʻomehana wale nā mīkini noe i ka wai - hoʻoheheʻe lākou me ka wela i kahi hui i hana ʻia. ʻO ka mea lawe kumu (maʻa mau propylene glycol, triethylene glycol, a i ʻole glycerin), ka pae maʻemaʻe, ka nui o nā ʻāpana ma hope o ka atomization, a me ke kūpaʻa wela ma 280-320°C e hoʻoholo i ka hana. Hoʻāʻo mākou i kēlā me kēia pūʻulu a mākou e hoʻohana ai i loko o ka hale-ʻaʻole me nā spectrometers lab wale nō, akā ma lalo o ka ukana maoli: hoʻomau i nā pōʻai he 45 mau minuke ma 95% kaʻina hana, nā mahana ambient mai 5°C a 38°C, a me ka haʻahaʻa a hiki i 90% RH.

ʻO nā wai maʻemaʻe haʻahaʻa e waiho i ke koena e hōʻiliʻili i loko o ka mea hoʻololi wela. ʻAʻole ma hope o nā pule—ma hope o ʻekolu a ʻelima mau hōʻike piha. Hoʻopili kēlā kūkulu ʻana i ka mea hoʻomehana, e koi ana i ka wela o ka ʻili. Ka hopena? ʻO ka hoʻohaʻahaʻa wela o ka wai i koe, ka ʻeleʻele ʻeleʻele, ka ʻala ʻala, a me ka hiki ʻole i ka wā o ka hoʻololi ʻoki ʻoki wela. Ua hōʻike aku kekahi mea kūʻai aku e hoʻololi ʻelua i ka poloka wela o kā lākou mīkini noe i loko o ʻewalu mahina—a hiki i ka wā i hoʻopaʻa ʻia ai kā lākou mea hoʻolako wai a loaʻa iā 12.7% ka nui o ka wai (ʻo ka nui o ka ʻoihana he 0.5%).

Hāʻawi nā wai kiʻekiʻe i ka viscosity hiki ke wānana i ka mahana hana. He lahilahi loa? ʻO ka overspray, pōkole ka manawa kau, haʻahaʻa haʻahaʻa. Mānoanoa loa? Hoʻohuhi piha ʻole, “mahu” keʻokeʻo ma kahi o ka noe maoli, kulu nozzle. Ana mākou i ka viscosity ma 30°C a me 60°C—ʻaʻole wale ka mahana o ka lumi—no ka mea, hiki i nā mīkini noe ke hiki i ke kaulike wela ma waena o ka pōʻai.

ʻEkolu Kūkākūkā Non-Negotiable no ka hoʻohana ʻoihana

E haʻalele i nā koi kūʻai. E noʻonoʻo i kēia mau ana i hōʻoia ʻia:

• Maʻemaʻe ≥99.8% — Hōʻoia ʻia e ka hoʻāʻo ʻana o GC-MS, ʻaʻole wale nā pepa SDS. ʻO ka wai, ethanol, a i ʻole ka methanol methanol e hoʻolalelale i ka ʻinoʻino i loko o nā ʻāpana kila kila.
• Ke kiko uila ≥110°C - He mea koʻikoʻi no nā wahi i loko me nā mākaʻi ahi. ʻO nā wai ma lalo o 105°C i hoʻāla i nā huaʻōlelo i loko o ʻelua mau loiloi hale kiʻiʻoniʻoni Beijing i ka makahiki i hala.
• Koe kaumaha ≤0.003g no 100ml ma hope o 30-min 300°C bake - Ana ʻia i loko o kā mākou lab ma ka pūnaewele. ʻOi aku ka maikaʻi o kēia ma mua o ka hōʻailona "koena haʻahaʻa".

Hōʻole mākou i nā wai me nā mea pena, nā mea ʻala, a i ʻole surfactants. Hoʻohaʻahaʻa ka wai ma lalo o ka UV a me ka wela—e waiho ana i ke kiʻi melemele ma luna o nā lens a me nā mea hana. ʻO nā mea ʻala e uhi i ke kinoea akā ʻaʻole e hoʻōki. ʻO nā surfactants e hoʻemi ikaika i ka ʻili o ka ʻili, e hāʻule ana ka noe ma mua o ka hiki ʻana i ka pae o ka lehulehu.

Hiki i kekahi ke hoʻopaʻapaʻa he palekana a maʻalahi hoʻi ka wai noe "wai-wai". Eia naʻe, ʻo ka "wai-wai" wale nō ke ʻano o ka wai - ʻaʻole ʻo ka wai ka mea lawe mua. ʻO ka propylene glycol/wai hui ʻia ka mea nui i ka mākeke, akā pono nā ratios. ʻO kahi hui 70/30 PG/wai e hana pono. ʻO kahi hui 40/60 e paila ʻole, kuha, a waiho i nā waihona mineral inā hoʻohana ʻia ka wai i ka hana ʻana.

Hoʻolikelike i ka wai me kāu Mīkini—a me kou Kaiapuni

ʻAʻole like nā mīkini noe a pau. ʻO nā ʻāpana kahiko me nā wili wela nickel-chrome e ʻae i nā kikoʻī wai ākea. Ke koi nei nā ʻāpana ceramic-core hou i ka hoʻomanawanui ʻoi aku ka paʻakikī. Hoʻopaʻa mākou i kēia i kēlā me kēia lā: i ka wā i hoʻonoho ai mākou i ka Robe BMFL Beam ma ka ʻaoʻao o ka noe ma kahi hōʻike ʻo Shenyang Olympic Sports Center, pono ka ʻoki ʻana i ka noe e hoʻomaha mālie. Hāʻawi ka wai maʻamau i 12 kekona o ka ʻike. ʻO kā mākou hui maʻamau 65/35 triethylene glycol/propylene glycol i hoʻonui ʻia i 37 kekona—me ka hoʻonui ʻole ʻana i ka inu wai.

Hoʻololi ke kiʻekiʻe i nā mea a pau. Ma 1,500m ma luna o ka ʻilikai (maʻa mau ma ke komohana ʻo Kina), hāʻule nā ​​paila paila. ʻO nā wai i hoʻomākaukau ʻia no ka hoʻohana ʻana i ka ʻilikai e mahuka loa i ke ala hānai—no ka hoʻoulu ʻana a me ka piʻi ʻana o ke kaomi. Ke kūʻai nei mākou i ʻelua mau ʻano like ʻole: hoʻokahi helu ʻia no ≤500m, ʻo kekahi i hōʻoia ʻia a hiki i 2,200m.

ʻO ke kiʻekiʻe wela ke koi aku i ka hoʻololi. Ma lalo o 10°C, mānoanoa ka wai maʻamau. Hāʻule ka puka. ʻO ka hoʻomaʻamaʻa mua ʻana i ka pūnāwai kōkua - akā inā paʻa ka wai. Ua hoʻāʻo mākou i nā hōʻailona 17 ma -5°C. ʻEhā wale nō i mālama ʻia ke kahe ʻana ma kahi puka 0.3mm me ka hoʻomehana ʻole. Ua hoʻohana ʻia nā ester glycerin i hoʻololi ʻia—ʻaʻole glycerin pololei.

ʻO ke koho ʻana i ka wai uahi he hoʻoholo i nā ʻōnaehana—ʻaʻole kahi mea laina

Hoʻopili pololei ʻia ke koho ʻana i ka wai uahi i kāu papa hoʻonohonoho mālama, ka pono o ka palapala hoʻokō, a me ka hilinaʻi noʻonoʻo. ʻO ka hoʻohana ʻana i ka wai non-OEM e hoʻopau i nā palapala hōʻoia o nā mea hana wela—ʻaʻole ma muli o ka kūpaʻa ʻana o ka brand, akā no ka mea, ʻaʻole i hōʻoia ʻia ka nānā ʻana o ke koena. Mālama mākou i kēia: nā mīkini e hoʻohana ana i ka wai haʻahaʻa haʻahaʻa i hōʻoia ʻia he 18 mahina ma waena o ka hoʻomaʻemaʻe nozzle. ʻO ka poʻe e hoʻohana ana i ka wai i hōʻoia ʻole ʻia he 4.3 mahina.

ʻAʻole ʻo ke kumukūʻai wale nō ke kumu kūʻai o ka lita. He mea paʻakikī ke hoʻokaʻawale i nā laina, ka manawa haʻahaʻa i ka wā ʻahaʻaina, nā ʻāpana pani, a me ka pilikia o ka inoa i ka wā e hāʻule ai ka noe ma waena o ka hana. ʻO ka wai he $28/lita e hoʻonui i ke ola wela ma 300% e uku iā ia iho ma lalo o ʻeono mau hanana.

Ua hoʻohui ʻo Shenyang Fei Ya Water Art Landscape Engineering Co., Ltd. i nā ʻōnaehana noe i loko o nā pūnāwai he 100 aʻe mai ka makahiki 2006 mai ka Harbin Ice Festival's sub-zero plumes a i nā pale noe o Dubai Fountain. Hoʻomaka kēlā me kēia hoʻolaha me ka hōʻoia wai. Loaʻa i kēlā me kēia mea kūʻai kahi pepa kikoʻī wai-ʻaʻole kahi brochure. No ka mea, ʻaʻole lewa ka noe. He ʻenekinia pololei, hoʻokuʻu ʻia i ka ea.

Hōʻike ka Smoke Fluid Selection i nā mea a kāu poʻe e ʻike ai-a me nā mea a kāu hui e mālama ai. E koho i ka wai e hana like i ke aumoe e like me ke awakea, i ka ua a me ka wela maloʻo, e hōʻike ma hope o ka hōʻike. ʻAʻole ia ka idealism. ʻO ia ka hoʻopaʻi hana.
