1、Nā ʻanuʻu kumu no ke koho ʻana
1. E hoʻoholo i keʻano hoʻomehana
-Ka hoʻomehana wai wai: He kūpono no nā ʻōnaehana pani me nā mahana ≤ 300 ℃, pono e uku ʻia i ka hopena o ka viscosity i ka wai.
-ʻO ka hoʻomehana ʻana o ke kinoea: kūpono no nā ʻōnaehana pani ʻia ma 280-385 ℃, me ka maikaʻi o ka hoʻoili wela kiʻekiʻe akā e koi ana i ke kūpaʻa wela kiʻekiʻe.
2. E hoʻonohonoho i ka pae wela
-Ka mahana hana kiʻekiʻe loa: Pono ʻo 10-20 ℃ haʻahaʻa ma mua o ka waiwai nominal o ka ʻaila hoʻoili wela (e like me 320 ℃ waiwai nominal, hoʻohana maoli ≤ 300 ℃) e pale i ka coking a i ʻole oxidation.
-Ka wela hana liʻiliʻi: Pono e hōʻoia ʻia ka viscosity ≤ 10mm ²/s (inā koi ʻia ka huli ʻana i ka wela i ka hoʻoilo e pale ai i ka paʻa).
3. ʻAno ʻōnaehana hoʻohālikelike
-Pūnaewele paʻa: Palekana kiʻekiʻe, kūpono no ka hana hoʻomau, ʻōlelo ʻia i ka ʻaila hoʻoili wela synthetic (e like me ka diphenyl ether mixture).
-Open system: Pono e koho i ka aila mineral me nā waiwai antioxidant ikaika (e like me L-QB300) a hoʻopōkole i ka pōʻai pani.
2、Ke koho ʻana i ke ʻano ʻaila hoʻoili wela
He haʻahaʻa ke kumu kūʻai haʻahaʻa o ke ʻano minerala a me ka paʻa wela wela, i kaupalena ʻia i ka hoʻohana ʻana i ka wai wai ≤ 300 ℃ LQB300 LQC320
Loaʻa i ke ʻano synthetic ke kūpaʻa wela ikaika (a hiki i 400 ℃) a kūpono ia no ka pae kinoea a me nā hiʻohiʻona wela kiʻekiʻe. He kūpono no ka 240 ℃ a me 400 ℃ biphenyl ether mixtures a me nā ʻano alkyl biphenyl
3、Nā palena hana koʻikoʻi
1. Thermal paʻa: Acid waiwai ≤ 0.5mgKOH / g a me ke koena kalapona ≤ 1.0% he mau paepae palekana, a pono ke pani hou ina ua oi aku i na kulana.
2. Palekana oxidation: ʻO ≥ 200 ℃ ka helu uila hāmama, a ʻoi aku ka kiʻekiʻe o ka paila mua ma mua o ka wela o ka hana.
3. Aloha kaiapuni: Pono e hāʻawi ʻia ka mea nui i nā aila hoʻoili wela synthetic non-toxic a biodegradable (e like me ke ʻano diphenyl ether).
4、Nā mālama koho
1. E pale i ka hoomaopopo ole:
-ʻAʻole hiki ke hoʻohana ʻia ka ʻaila mineral i loko o nā ʻōnaehana gas-phase, inā ʻaʻole ia e maʻalahi i ka oxidation a me ka leakage.
-Paʻa nā ʻōnaehana paʻa i ka hoʻohana ʻana i ka wahi hoʻolapalapa haʻahaʻa a me nā aila volatile.
2. Brand a me ka palapala hōʻoia:
-E koho i nā huahana i hōʻoia ʻia e like me GB23971-2009 maʻamau a nānā i nā hōʻike hoʻāʻo ʻekolu.
-E hoʻokumu i nā hōʻailona e hāʻawi i ka lawelawe ma hope o ke kūʻai aku, e like me Great Wall Thermal Oil a me Tongfu Chemical.
5、Manaʻo mālama
-Ka ho'āʻo maʻamau: Hoʻāʻo ʻia ka waiwai waikawa a me ke koena kalapona i kēlā me kēia ʻeono mahina, a loiloi ʻia nā loli viscosity i kēlā me kēia makahiki.
-System sealing: Pono nā ʻōnaehana paʻa i ka palekana nitrogen, aʻo nā ʻōnaehana wehe e koi i nā pōkole hoʻomaʻemaʻe pōkole.
Inā makemake ʻoe e ʻike hou aku e pili ana i kā mākou huahana, e ʻoluʻolukāhea iā mā˚ou!
