Imitha yeoli ye-infrared sisixhobo esisetyenziselwa ngokukodwa ukulinganisa umxholo weoli emanzini. Isebenzisa umgaqo we-infrared spectroscopy ukuhlalutya ngokobungakanani ioli emanzini. Ineenzuzo zokukhawuleza, ezichanekileyo kunye nezilungeleyo, kwaye zisetyenziswa ngokubanzi esweni lomgangatho wamanzi, ukukhuselwa kwendalo kunye nezinye iindawo.
I-oyile ngumxube wezinto ezahlukeneyo. Ngokutsho kwe-polarity yamacandelo ayo, inokwahlulwa ibe ngamacandelo amabini: i-petroleum kunye ne-oyile yezilwanyana kunye nemifuno. Isilwanyana se-polar kunye ne-oyile yemifuno inokubhengezwa ngezinto ezifana ne-magnesium silicate okanye i-silica gel.
Izinto ze-petroleum zenziwa ikakhulu ziikhompawundi ze-hydrocarbon ezifana ne-alkanes, i-cycloalkanes, ii-hydrocarbons ezinuka kamnandi, kunye ne-alkenes. Umxholo we-hydrocarbon ubalelwa kwi-96% ukuya kwi-99% yetotali. Ukongezelela kwiihydrocarbons, izinto zepetroleum zikwanazo neoksijini encinane, initrogen, nesalfure. Iimveliso zeHydrocarbon zezinye izinto.
Ioyile yezilwanyana kunye nemifuno ibandakanya ioyile yezilwanyana kunye neoyile yemifuno. Ioyile yezilwanyana ziioyile ezithathwe kwizilwanyana. Zinokwahlulwa ngokubanzi zibe yioyile yezilwanyana ezisemhlabeni kunye neoyile yezilwanyana zaselwandle. Ioyile zemifuno ziioyile ezifumaneka kwiziqhamo, kwimbewu, nakwintsholongwane zezityalo. Amacandelo aphambili e-oyile yemifuno yi-linear ephezulu ye-fatty acids kunye ne-triglycerides.
Imithombo yongcoliseko lweoyile
1. Izinto ezingcolisa ioyile kokusingqongileyo ubukhulu becala ziphuma kumanzi amdaka emizi-mveliso nakwilindle lasekhaya.
2. Amashishini angundoqo akhupha izinto ezingcolisa i-petroleum ikakhulu ngamashishini afana nokutsalwa kwe-oyile ekrwada, ukusetyenzwa, ukuthuthwa kunye nokusetyenziswa kwee-oyile ezisulungekisiweyo ezahlukeneyo.
3. Ioyile yezilwanyana kunye nemifuno iphuma ikakhulu kugutyulo lwasekhaya kunye nogutyulo lweshishini lokutya. Ukongeza, imizi-mveliso efana nesepha, ipeyinti, i-inki, irabha, ukuthambisa ulusu, amalaphu, izinto zokuthambisa kunye namayeza nawo akhupha ioyile yezilwanyana nemifuno.
Iingozi zokusingqongileyo ze-oyile ① Ubungozi kwiipropati zamanzi; ② Ukonakaliswa komhlaba okusingqongileyo; ③ Ukwenzakala kwezokuloba; ④ Ukwenzakala kwizityalo zasemanzini; ⑤ Ukwenzakala kwizilwanyana zasemanzini; ⑥ Ukwenzakala emzimbeni womntu
1. Umgaqo wemitha yeoli ye-infrared
Umtshina we-oyile ye-infrared luhlobo lwesixhobo esisetyenziswa ngokubanzi kwiinkqubo zokubeka iliso kokusingqongileyo, ishishini lepetrochemical, ihydrology kunye nokugcinwa kwamanzi, iinkampani zamanzi, amaziko okucoca ugutyulo, izityalo zamandla ashushu, iinkampani zentsimbi, uphando lwezenzululwazi kunye nokufundisa eyunivesithi, ukubeka iliso kubume bezolimo, ukujongwa kwendawo kaloliwe. , ukwenziwa kweemoto, iZixhobo zaselwandle zokubeka iliso kokusingqongileyo, ukubeka iliso kokusingqongileyo kwezithuthi, uphando lwezenzululwazi ngokusingqongileyo kunye namanye amagumbi ovavanyo kunye neelebhu.
Ngokukodwa, imitha yeoli ye-infrared ilayita isampuli yamanzi kumthombo wokukhanya kwe-infrared. Iimolekyuli zeoyile kwisampulu yamanzi ziya kutsala inxalenye yokukhanya kwe-infrared. Isiqulatho seoli singabalwa ngokulinganisa ukukhanya okufunxayo. Ngenxa yokuba izinto ezahlukeneyo zifunxa ukukhanya kubude obuhlukeneyo kunye nokuqina, iintlobo ezahlukeneyo zeoyile zinokulinganiswa ngokukhetha izihluzi ezithile kunye nezixhobo zokubona.
Umgaqo wayo wokusebenza usekelwe kumgangatho we-HJ637-2018. Okokuqala, i-tetrachlorethylene isetyenziselwa ukukhupha izinto zeoli emanzini, kwaye i-extract iyonke ilinganiswa. Emva koko i-extract idsorbed nge-magnesium silicate. Emva kokuba izinto ze-polar ezifana nezilwanyana kunye neoli yemifuno zisusiwe, ioli iyalinganiswa. ububele. I-extract epheleleyo kunye nomxholo we-petroleum unqunywe ngamanani amaza e-2930cm-1 (i-vibration yokwelula i-CH bond kwiqela le-CH2), i-2960cm-1 (i-vibration eyolulayo ye-CH bond kwiqela le-CH3) kunye ne-3030cm-1 (i-hydrocarbons enamakha). I-absorbection kwi-A2930, A2960 kunye ne-A3030 kwi-vibration eyolulayo ye-CH bond) ibalwe. Umxholo wezilwanyana kunye neoli yemifuno ibalwa njengomahluko phakathi kwesicatshulwa esipheleleyo kunye nomxholo wepetroleum. Phakathi kwabo, amaqela amathathu, i-2930cm-1 (CH3), i-2960cm-1 (CH2), kunye ne-3030cm-1 (i-hydrocarboni enuka kamnandi), ezona zixhobo ziphambili ze-petroleum mineral oils. "Nayiphi na i-compound" ekubunjweni kwayo "inokudityaniswa" kula maqela mathathu. Ngoko ke, kunokubonwa ukuba ukuzimisela komxholo wepetroleum kufuna kuphela inani lamaqela amathathu angentla.
Ukusetyenziswa kwansuku zonke kwee-oil detectors ze-infrared zibandakanya kodwa azikhawulelwanga kwiimeko ezilandelayo: Inokulinganisa umxholo we-petroleum, njenge-oyile yamaminerali, i-oyile ye-injini eyahlukeneyo, i-oyile ye-mechanical, i-lubricating oils, i-synthetic oils kunye ne-additives ezahlukeneyo eziqulethwe okanye zongeza; ngaxeshanye Umxholo onxulumeneyo we-hydrocarbons ezifana ne-alkanes, i-cycloalkanes kunye nee-hydrocarbons ezinevumba elimnandi nazo zinokulinganiswa ukuqonda umxholo we-oyile emanzini. Ukongeza, i-infrared oil detectors ingasetyenziselwa ukulinganisa i-hydrocarbons kwizinto eziphilayo, ezifana ne-organic matter eveliswa ngokuqhekezwa kwe-petroleum hydrocarbons, i-fuel ezahlukeneyo, kunye neemveliso eziphakathi kwinkqubo yokuvelisa izinto eziphilayo.
