I-HFC (Amanzi - I-Glycol Flame Simelana ne-Hydraulic fluid)
I-HFC hydraulic fluid uhlobo lwe-flueric olumelana nelangabi olungamelana namanzi angama-30% ~ 55% (Amanzi afakwe emanzini), ama-polylene anthycol noma ama-anti, anti - ukugqwala, ukungcola kanye nezinye izithasiselo. Amanzi angenye yezakhi ze-flame retardant, futhi uketshezi lunokumelana okuhle kwelangabi, inkomba ephezulu ye-viscosity, ukuqina okuhle kanye nokwakheka kweqiniso, futhi kuyikhambi leqiniso elisobala.
Ngenxa yokuqukethwe kwamanzi okukhulu, izinga lokushisa elisetshenzisiwe alikwazi ukwedlula i-65 ° C, ngokuvamile elisetshenziswe ohlelweni olungaphezulu kwengcindezi yama-20MPA, futhi ku-magneral materal njengamaminerali, futhi kuvame ukuguquguquka. Kukhethwe ngokukhethekile i-epoxy - Izambatho ezisekelwe ezisetshenziselwa ukugqoka.
Uketshezi lwe-Ethylene Glycol unobuthi obuthile, kepha inqobo nje uma kuvinjelwa ukungena emlonyeni, ngeke kubangele ukulimala emzimbeni womuntu. Amanzi - Isixazululo se-Ethylene Glycol kufanele sibhekwe njalo nge-viscosity, okuqukethwe kwamanzi kanye nezinguquko ze-PH. Uma i-viscosity nenani le-PH lidlula inkomba ecacisiwe, amanzi kanye nezithasiselo kufanele zengezwe. Lapho kunodoti omkhulu kakhulu, uketshezi kufanele lukhishwe ngokuhlunga.
Izinzuzo ze-HFC kanye nobunzima
Ilungiselelwe ngenhlanganisela yamanzi ne-ethylene glycol njengesithako esiyisisekelo (ngokusho kohlelo oluthile lwefomula liyahlukahlukana kusuka ku-40 - u-anti - ukugqwala, kanye nezindleko eziphelele zokwakha ziphansi kunezokwenziwa u-Ester hydraulic uwoyela. Ngenxa yamanzi - uhlelo olususelwa, ukusebenza kwamalangabi, ukumelana nelangabi kanye nesakhiwo esikhethekile samakhemikhali senza amanzi - I-glycol hydraulic fluid inendawo ephansi yokuthwebula (ngokuvamile i-°
Kodwa-ke, amanzi - Imikhiqizo esekwe nayo izoba nezimpawu zemvelo njengezindaba ze-hydraulic, ikakhulukazi kulezi zinto ezilandelayo:
.
.
. Enqubweni yokusebenzisa, ngenxa yokuthambekela kwamanzi, kuyadingeka ukuphinda ugcwalise umkhiqizo kawoyela njalo, futhi inzuzo yentengo yomkhiqizo kawoyela kunzima ukwenza ukusetshenziswa kwenani.
HFDU (fatty acid ester / zokwenziwa ester hlobo Flame Retame Retacrarant Hydraulic fluid)
Uhlobo lwe-hydraulic olumelana ne-ester luhlukaniswe ngohlobo lwe-phosphate ester (HEDR) nohlobo lwamafutha acid acid ester (HFDU). Amafutha e-HFDU hydraulic asuselwa kumafutha e-Synthetic Ester angeziwe futhi ahlanganiswe nezithasiselo nge-anti - i-anti - ukugqwala kanye ne-anti -
Amafutha e-Fatty Acid Ester amelana ne-hydraulic ane-hydraulic eqinile, okuphezulu nokushisa okushisa, uhla lokushisa olubanzi, i-biodegrability kanye nempilo ende, amandla kagesi kanye nezinye izimboni ezithintana namazinga okushisa aphezulu noma ovulekile we-Flame Hydraulic Amafutha e-Fatty Acid ester ye-Hydraulic u-Hydraulic abiza ngaphezulu kwama-2 izikhathi ezibiza ngamafutha amaminerali uthayela we-hydraulic, ngakho-ke asetshenziswa kuphela kuzinhlelo zokusebenza lapho kuvela khona ilangabi kanye ne-bioderHulayomabilibility.
HFDU Okubi Nama-Advantages
I-HFDU Hydraulic Amafutha inezinkomba eziphakeme ze-viscosity, ukuze isheke kahle, i-viscosity ngeke iguquke kakhulu lapho kuncipha ukushisa, futhi izici ze-viscosity zincono kancane, futhi ukuguqulwa kwezinto ezibonakalayo kunconywa kakhulu yingcindezi yokuqinisekisa ukuthi ingaphezulu lokushayisana.
Kodwa-ke, lapho kufakwa uwoyela we-HFDU hydraulic uwoyela, kuzokwenzeka ukusabela kwama-hydrolysis lapho kuhlangana namanzi, okuzokhulisa i-acid, kanye nokuhambisana kwe-HFDU Hydraulic uwoyela nge-zinc - Ezinye izinhlobo zokwakheka kwe-Flame retardant fordraulic fluids zenzelwe izinhlelo ezithile. I-anhydrous polyther flame retardant i-hydraulic fluids inempilo yenkonzo ende futhi inobungane kakhulu, i-silicone fluids isetshenziswa kwezinye izimo ezibucayi, kepha lezi ezinye izinhlobo zokwehla kwe-hydraulic fluids zibiza kakhulu.
Ngenxa yezinzuzo zemvelo zamafutha e-Synthetic Ester Base Fails, anikela ngezinzuzo ezibalulekile njengezindaba zokuthambisa ngaphezulu kwamanzi -

Umehluko phakathi kwe-HFC ne-HFDU
Ngenkathi womabili uketshezi lwe-HFC neHFDU Hydraulic lunganciphisa ubungozi bomlilo, ngcono ukuphepha okusebenzayo, futhi uthuthukise ukusebenza kwemvelo, kunomehluko omkhulu. Ngamazinga wokutholwa kwemakethe wama-50 - ama-55%, i-HFC ingamanzi - uketshezi olususelwa olungasetshenziswa kuzo zonke izimboni lapho kunengozi enkulu yomlilo. Ngokuphambene, i-HFDU iyi-fluid ye-anhydrost eyenzelwe ukubuyisela u-anti - Gqoka uwoyela wamaminerali - Kususelwa ku-hydraulic fluids ngentengo yokutholwa kwemakethe ye-20 - 25%. (Umthombo: URonald Knecht waseVoker Hearton)
Ngenkathi indima ebalulekile yalezi fluids ezimbili ukuvikela ukulahleka kwezimali okubangelwa umlilo kanye nokuphumula kwesicelo, ukukhethwa kwawo okuzokwamukela ngokuningi kuncike kwizidingo ezithile zohlelo lokusebenza. Isibonelo, kuzinhlelo zokusebenza nabasebenzi, njengokudla okufa, ukumelana nomlilo okungaguquki kwama-HFC kuvame ukuthandwa. Ngenkathi kusetshenziswa izicelo ezingafakwanga njengezinto ezivuthayo, ukuthembeka kohlelo okuthuthukisiwe okunikezwe yiHfdus kuvame ukushayela isinqumo - Ukwenza.
Ngenkathi kukhona igumbi lokuguqula langempela - Izicelo zomhlaba ezivela ku-HFC ziye ku-HFDU, inqubo iyabiza futhi idinga ukugcwala okubanzi nokuhlolwa okubanzi. Ngakho-ke, kubalulekile ukuqonda kusukela ekuqaleni lapho i-hydraulic fluid yenza umqondo omuhle kakhulu ngokuphepha kokuphepha, izindleko kanye nemvelo ukubheka izinzuzo ezihambisana nokukhiqizwa okwengeziwe, isikhathi esehlisiwe kanye nokuphepha komsebenzi othuthukisiwe kanye nokuphepha komsebenzi okuthuthukisiwe.
Izicelo zamanzi we-HFC - I-Glycol hydraulic fluid
I-HFC (Amanzi - I-Glycol) ingenye yezinto ezisetshenziswa kakhulu i-hydractional hydraulic fluids futhi zithandwa ngezindleko zazo - ukusebenza kanye nokuhlanganiswa kokumelana nomlilo okuhle kakhulu ngezakhiwo ezinhle. Ama-HFC asetshenziswa kabanzi e-weblemaking, efa ngokuxoshwa, ukucindezela kwakha, kanye nomkhakha wezimoto, bese uqhubeka nokukhetha okujwayelekile embonini.
Ngokungeziwe kwizakhiwo zayo ezithembekile eziphikisanayo, ezinye izizathu zokukhetha i-HFC zifaka ukuvunywa kwe-OEM kanye nezindleko ezifana namafutha amaminerali. Ngokungafani ne-HFdus, ama-HFC angaxutshwa namanzi enqubo, okubalulekile ngenxa yezizathu zezemvelo.
Kepha esimweni sezinhlelo zokusebenza ze-HFC, ukulungiswa okuqhubekayo kubalulekile, futhi isampula ejwayelekile nokuhlaziywa kungavimbela ukulimala kwengxenye ebizayo. Uma kugcinwa kahle, izinhlelo zohlelo lokusebenza lwe-HFC zingasebenza ngokuthembekile kakhulu. Ukunganaki ukulungiswa kungaholela ekushayweni okungahlelwanga, ngakho-ke isikhathi sokuphumula kufanele sihlelelwe ngokucophelela ukunciphisa ukuphazamiseka nemali elahlekile. Ngohlelo lokulungiswa olusebenzayo endaweni, izinzuzo ze-HFC ngokuya nge-Long - Izindleko zethemu - Ukusebenza kahle nokuphepha kucacile. Ngenkathi izakhiwo zokumelana nomlilo zama-HFC ziyancomeka, amanzi - Uketshezi olususelwa ku-Fluid lungaholela empilweni yezakhi emfushane ngenxa yokugqwala kanye nokuvunyelwa uma ukulungiswa kunganakwa.
Ukusetshenziswa kwe-HFdu Fatty Acid Ester yohlobo lwe-hydraulic fluids
Naphezu kwentengo yayo ephezulu, i-HFDUS ngokuvamile yamukelwa njengenye indlela yokuphikisa ehlelekile kumafutha amaminerali ezinhlobonhlobo ze-hydraulic ngezidingo ezikhethekile zemvelo ngaphandle kokuyekethisa ukusebenza nohlelo lwe-hydraulic.
I-HFDUS ibiza amahlandla amabili kuya kathathu njengama-mineral uiwoyela, futhi ngenkathi izindleko zokuqala zingaba ngaphezulu, ukusetshenziswa kwamandla kungancishiswa ngokunciphisa izindleko eziphelele ngenxa yokunciphisa isikhathi sokugcina kanye nokuthambisa okuthuthukile. Ngaphezu kwalokho, i-HFdus inempilo yenkonzo ende futhi ingasebenza ezingcindezini zokusebenza okuphezulu, ngaleyo ndlela ithuthukise ukuthembeka kohlelo.
Ukumelana nomlilo kwe-HFdus kuhlangana namazinga aphesheya anjenge-Factory Mutual futhi kufanelekile ukuthola izicelo lapho kunengozi yomlilo, njll., Futhi lapho ukuthembeka kohlelo kubalulekile, kuvame ukukhetha okungcono. Njengoba i-HFdus ayinangqondo ngamanzi, ayihlanganisi namanzi amdaka, kepha lokhu kungaholela ekufunweni okuphezulu kwe-oxygen chedgen (cod) neminye imiphumela yemvelo neyokulawula. Lapho unesisindo sezinzuzo ezihambisana namanzi - Mahhala namanzi - izixazululo ezisuselwa ku-based, kufanele kubhekwe umbono ophelele.
Sekukonke, ama-HFCs ne-HFUS anezinzuzo zawo, ama-HFC abiza kancane kepha angenisa ezinye izinselelo ngokuya ngomthelela wesondlo kanye nomthelela wezemvelo, ngenkathi i-HFdus inikela kangcono kakhulu - Lapho ukhetha uketshezi olungalungile lwe-hydraulic, izinqumo zidinga ukwenziwa ngokususelwa kwizidingo ezithile zohlelo lokusebenza, izingqinamba zesabelomali, kanye nokucatshangelwa kwemvelo.
