1,Zofunikira pakusankha
1. Dziwani njira yotenthetsera
-Kutentha kwa gawo lamadzi: Oyenera machitidwe otsekedwa ndi kutentha ≤ 300 ℃, chidwi chiyenera kuperekedwa ku zotsatira za viscosity pa fluidity.
-Kutentha kwa gawo la gasi: koyenera kumakina otsekedwa pa 280-385 ℃, ndi kutentha kwakukulu kotengera kutentha koma kumafuna kukhazikika kwamafuta.
2. Khazikitsani kutentha
-Kutentha kwakukulu kwa ntchito: Kuyenera kukhala 10-20 ℃ kutsika kuposa mtengo wamtengo wapatali wa mafuta otumizira kutentha (monga 320 ℃ mtengo wadzina, kugwiritsa ntchito kwenikweni ≤ 300 ℃) kupewa coking kapena oxidation.
-Kutentha kwapang'onopang'ono: Kukhuthala kuyenera kutsimikiziridwa kukhala ≤ 10mm ²/s (ngati kutentha kumafunika m'nyengo yozizira kuteteza kulimba).
3. Kufananiza dongosolo mtundu
-Makina otsekedwa: Chitetezo chachikulu, choyenera kugwira ntchito mosalekeza, mafuta opangira kutentha opangira kutentha (monga diphenyl ether mix).
-Open System: Ndikofunikira kusankha mafuta amchere okhala ndi antioxidant wamphamvu (monga L-QB300) ndikufupikitsa kuzungulira kwa m'malo.
2,Kusankha mtundu wa mafuta otengera kutentha
Maminolo mtundu ali mtengo otsika ndi pafupifupi matenthedwe bata, malire ntchito madzi gawo ≤ 300 ℃ LQB300 LQC320
Mtundu wopangidwawo uli ndi kukhazikika kwamphamvu kwamafuta (mpaka 400 ℃) ndipo ndi yoyenera pagawo la mpweya komanso kutentha kwambiri. Ndiwoyeneranso kusakaniza kwa 240 ℃ ndi 400 ℃ biphenyl ether ndi mitundu ya alkyl biphenyl.
3,Zofunikira zazikulu zogwirira ntchito
1. Kukhazikika kwa kutentha: Phindu la asidi ≤ 0.5mgKOH / g ndi carbon yotsalira ≤ 1.0% ndizofunika chitetezo, ndipo m'malo mwake zimafunika ngati zikupitirira miyezo.
2. Chitetezo cha okosijeni: Malo otsegula otsegula ndi ≥ 200 ℃, ndipo malo otentha oyambilira ndi apamwamba kuposa kutentha kwakukulu kogwira ntchito.
3. Ubwenzi wa chilengedwe: Chofunika kwambiri chiyenera kuperekedwa kwa mafuta omwe sali owopsa komanso owonongeka opangidwa ndi kutentha (monga diphenyl ether type).
4,Njira zodzitetezera
1. Pewani kusamvana:
-Mineral mafuta sangathe kugwiritsidwa ntchito mu gasi-gawo machitidwe, apo ayi sachedwa makutidwe ndi okosijeni ndi kutayikira.
-Makina otsekedwa amaletsa kugwiritsa ntchito mafuta ochepa owiritsa komanso mafuta osakhazikika.
2. Chizindikiro ndi Chitsimikizo:
-Sankhani zinthu zotsimikiziridwa molingana ndi GB23971-2009 muyezo ndikuwona malipoti oyesa a chipani chachitatu.
-Ikani patsogolo ma brand omwe amapereka ntchito zogulitsa pambuyo pogulitsa, monga Great Wall Thermal Oil ndi Tongfu Chemical.
5,Malingaliro osamalira
-Kuyesa pafupipafupi: Mtengo wa asidi ndi kaboni yotsalira imayesedwa miyezi isanu ndi umodzi iliyonse, ndipo kusintha kwa viscosity kumawunikidwa chaka chilichonse.
-System kusindikiza: Makina otsekedwa amafunikira chitetezo cha nayitrogeni, pomwe makina otseguka amafunikira kuyeretsa kwakanthawi kochepa.
Ngati mukufuna kudziwa zambiri za mankhwala athu, chondeLumikizanani nafe!
