1,Amanyathelo angundoqo okhetho
1. Qinisekisa indlela yokufudumala
-Ukufudumeza kwesigaba samanzi: Kufanelekile kwiinkqubo ezivaliweyo kunye namaqondo okushisa ≤ 300 ℃, ingqalelo kufuneka ihlawulwe kwimpembelelo ye-viscosity kwi-fluidity.
-Ukufudumeza kwesigaba segesi: ezifanelekileyo kwiinkqubo ezivaliweyo kwi-280-385 ℃, kunye nokusebenza kakuhle kokutshintshwa kobushushu kodwa kufuna ukuzinza okuphezulu kwe-thermal.
2. Misela uluhlu lobushushu
-Iqondo eliphezulu lobushushu bokusebenza: Kufuneka libe yi-10-20 ℃ ngaphantsi kwexabiso lexabiso le-oyile yokudlulisa ubushushu (njenge-320 ℃ ixabiso eliqhelekileyo, ukusetyenziswa kwangempela ≤ 300 ℃) ukuphepha ukupheka okanye i-oxidation.
-Ubuncinci bobushushu bokusebenza: I-viscosity kufuneka iqinisekiswe ukuba ≤ 10mm ²/s (ukuba ukufunwa kobushushu kuyafuneka ebusika ukunqanda ukuqina).
3. Uhlobo lwenkqubo ehambelanayo
-Isistim evaliweyo: Ukhuseleko oluphezulu, olulungele ukusebenza ngokuqhubekayo, ioli ekhuthazwayo yokutshintshwa kobushushu bokwenziwa (njengomxube we-diphenyl ether).
-Inkqubo evulekileyo: Kuyimfuneko ukuba ukhethe ioli yamaminerali kunye nezixhobo ezinamandla ze-antioxidant (ezifana ne-L-QB300) kwaye unciphise umjikelezo wokutshintshwa.
2,Ukukhethwa kohlobo lweoli yokudlulisa ubushushu
Uhlobo lwezimbiwa lunexabiso eliphantsi kunye nozinzo oluqhelekileyo lwe-thermal, olulinganiselwe kusetyenziso lwesigaba solwelo ≤ 300 ℃ LQB300 LQC320
Uhlobo lwe-synthetic lunozinzo oluqinileyo lwe-thermal (ukuya kwi-400 ℃) kwaye lufanelekile kwisigaba segesi kunye neemeko eziphezulu zokushisa. Ikwalungele i-240 ℃ kunye ne-400 ℃ imixube ye-biphenyl ether kunye neentlobo ze-alkyl biphenyl.
3,Iiparamitha zokusebenza eziphambili
1. Ukuzinza kwe-Thermal: Ixabiso le-Acid ≤ 0.5mgKOH / g kunye nekhabhoni eseleyo ≤ I-1.0% yimiqobo yokhuseleko, kwaye ukutshintshwa kuyafuneka ukuba kudlula imigangatho.
2. Ukhuseleko lwe-oxidation: I-flash point evulekileyo yi-≥ 200 ℃, kwaye indawo yokubilisa yokuqala iphezulu kunobushushu bokusebenza.
3. Ubuhlobo bendalo: Okuphambili kufuneka kunikwe kwi-oyile yokuhambisa ubushushu bokwenziwa kwe-non-toxic kunye ne-biodegradable (njenge-diphenyl ether type).
4,Ukukhetha ukhetho
1. Kuphephe ukungaqondani:
-Ioyile yamaminerali ayinakusetyenziswa kwiinkqubo zesigaba segesi, ngaphandle koko ixhomekeke kwi-oxidation kunye nokuvuza.
-Iinkqubo ezivaliweyo zivimbela ukusetyenziswa kwendawo yokubilisa ephantsi kunye neoli eguqukayo.
2. Uphawu kunye neSiqinisekiso:
-Khetha iimveliso eziqinisekisiweyo ngokwe-GB23971-2009 standard kwaye ujonge iingxelo zovavanyo lomntu wesithathu.
-Ukubeka phambili iimpawu ezibonelela ngenkonzo emva kokuthengisa, njengeGreat Wall Thermal Oil kunye neTongfu Chemical.
5,Iingcebiso zokugcina
-Uvavanyo oluqhelekileyo: Ixabiso le-Acid kunye nekhabhoni eseleyo ivavanywa rhoqo kwiinyanga ezintandathu, kwaye utshintsho lwe-viscosity luvandlakanywa ngonyaka.
-Ukutywinwa kweSystem: Iinkqubo ezivaliweyo zifuna ukukhuselwa kwe-nitrogen, ngelixa iinkqubo ezivulekileyo zifuna imijikelo emifutshane yokucoca.
