1,Izinyathelo ezibalulekile zokukhetha
1. Thola indlela yokushisa
Ukushisa kwesigaba samanzi: Kufanelekile kumasistimu avaliwe anamazinga okushisa ≤ 300 ℃, ukunakwa kufanele kukhokhwe emthelela we-viscosity ku-fluidity.
-Ukushisa kwesigaba segesi: kulungele izinhlelo ezivaliwe ku-280-385 ℃, ngokusebenza kahle kokudlulisa ukushisa kodwa kudinga ukuzinza okuphezulu kokushisa.
2. Setha izinga lokushisa
-Izinga lokushisa eliphezulu lokusebenza: Kufanele libe ngu-10-20 ℃ ngaphansi kwenani elivamile lamafutha okudlulisa ukushisa (njenge-320 ℃ inani legama, ukusetshenziswa kwangempela ≤ 300 ℃) ukuze kugwenywe ukupheka noma i-oxidation.
-Izinga lokushisa elincane lokusebenza: I-viscosity kufanele iqinisekiswe ukuthi ingu-≤ 10mm ²/s (uma ukulandelela ukushisa kudingekile ebusika ukuze kuvinjelwe ukuqina).
3. Ukufanisa uhlobo lwesistimu
-Isistimu evaliwe: Ukuphepha okuphezulu, okufanelekile ukusebenza okuqhubekayo, uwoyela wokudlulisa ukushisa owenziwe onconywayo (njengengxube ye-diphenyl ether).
-Isistimu evulekile: Kuyadingeka ukukhetha amafutha amaminerali anezakhiwo ezinamandla ze-antioxidant (ezifana ne-L-QB300) futhi unciphise umjikelezo wokubuyisela.
2,Ukukhethwa kohlobo lwamafutha okudlulisa ukushisa
Uhlobo lwamaminerali lunentengo ephansi kanye nokuzinza okujwayelekile okushisayo, kukhawulelwe ekusetshenzisweni kwesigaba soketshezi ≤ 300 ℃ LQB300 LQC320
Uhlobo lokwenziwa lunokuqina okushisayo okuqinile (kufika ku-400 ℃) futhi lufanele isigaba segesi kanye nezimo zokushisa okuphezulu. Ilungele futhi ingxube ye-biphenyl ether engu-240 ℃ no-400 ℃ nezinhlobo ze-alkyl biphenyl.
3,Imingcele yokusebenza engukhiye
1. Ukuzinza kokushisa: Inani le-asidi ≤ 0.5mgKOH/g kanye nekhabhoni esele ≤ 1.0% yimingcele yokuphepha, futhi ukushintshwa kuyadingeka uma kudlula izindinganiso.
2. Ukuphepha kwe-oxidation: Iphoyinti elikhanyayo ngu-≥ 200 ℃, futhi indawo yokubilisa yokuqala ingaphezulu kwezinga lokushisa eliphezulu lokusebenza.
3. Ubungane bemvelo: Okuhamba phambili kufanele kunikezwe amafutha angenabuthi futhi abolayo okwenziwa okudlulisa ukushisa okwenziwa (njengohlobo lwe-diphenyl ether).
4,Izinyathelo zokuphepha zokukhetha
1. Gwema ukungezwani:
- Amafutha amaminerali angeke asetshenziswe ezinhlelweni zesigaba segesi, ngaphandle kwalokho athambekele ekungeneni kwe-oxidation nokuvuza.
-Amasistimu avaliwe avimbela ukusetshenziswa kwephuzu eliphansi lokubilisa kanye namafutha aguquguqukayo.
2. Ibhrendi nesitifiketi:
-Khetha imikhiqizo eqinisekisiwe ngokwezinga le-GB23971-2009 futhi ubuke imibiko yokuhlola evela eceleni.
-Beka kuqala amabhrendi anikezela ngesevisi yangemuva kokuthengisa, njengeGreat Wall Thermal Oil kanye neTongfu Chemical.
5,Iziphakamiso zesondlo
-Ukuhlola okuvamile: Inani le-asidi ne-carbon eyinsalela ihlolwa njalo ngemva kwezinyanga eziyisithupha, futhi izinguquko ze-viscosity zihlolwa minyaka yonke.
-Ukuvalwa kwesistimu: Amasistimu avaliwe adinga ukuvikelwa kwe-nitrogen, kuyilapho amasistimu avulekile adinga imijikelezo yokuhlanza emifushane.
Uma ufuna ukwazi okwengeziwe ngomkhiqizo wethu, sicelaXhumana nathi!
