Embonini yamakhemikhali, i-phenol, njengento ebalulekile yamakhemikhali eluhlaza, isetshenziswa kabanzi kwezemithi, amakhemikhali amahle, ama-dyestuffs neminye imikhakha. Ngokuqiniswa kokuncintisana kwezimakethe kanye nokuthuthukiswa kwezimfuneko zekhwalithi, ukukhetha abahlinzeki be-phenol abathembekile sekubaluleke kakhulu. Lesi sihloko sizokwenza ukuhlaziya okujulile kokuthi ungabakhetha kanjani abahlinzeki be-phenol abafanelekile ezicini ezimbili zamazinga ekhwalithi namakhono okuthenga, ukuze sisize abasebenza embonini yamakhemikhali ukwenza izinqumo ezinolwazi.
Izakhiwo kanye nezicelo ze-Phenol
Izakhiwo Eziyisisekelo zePhenol
I-Phenol iyikhemikhali engenambala nengenaphunga enefomula yamangqamuzana engu-C6H5OH. Kuyinto ene-asidi enenani le-pH elingaba ngu-0.6, elincibilika kalula kuzincibilikisi zemvelo kodwa ezingancibiliki emanzini. Ngenxa ye-acidity eqinile, ukunakwa okukhethekile kufanele kukhokhwe ekuvikelweni ngesikhathi sokusetshenziswa.
Izinkambu Zokusebenza Eziyinhloko ze-Phenol
Ngenxa yezakhiwo zayo zamakhemikhali eziyingqayizivele, i-phenol isetshenziswa kakhulu kwezokwelapha, izithasiselo zokudla, odayi, ekwenziweni kwepulasitiki neminye imikhakha. Emkhakheni wemithi, i-phenol ivame ukusetshenziswa ekukhiqizeni ama-anticoagulants, ama-disinfectants, njll; embonini yokudla, ingasetshenziswa njengesilondolozi kanye nombala.
Izinto Ezibalulekile Zokukhetha Abahlinzeki Be-Phenol
Iziqu Zomphakeli Nezitifiketi
Lapho ukhetha i-aumphakeli we-phenol, kuyadingeka ukunaka ukuba semthethweni kwemibhalo yabo yokufaneleka njengamalayisense ebhizinisi namalayisense okukhiqiza. Izitifiketi zokuhlolwa kwemvelo ezikhishwe iminyango efanele yokuvikela imvelo kanye nezitifiketi zekhwalithi yomkhiqizo (njenge-USP, UL, njll.) nazo ziyimibandela ebalulekile.
Amandla Okukhiqiza kanye Nezisetshenziswa
Ukuthi umthamo wokukhiqiza womphakeli nezinto zokusebenza ziyahlangabezana yini nezindinganiso zomkhakha kuthinta ngokuqondile ikhwalithi yomkhiqizo. Umphakeli onokwethenjelwa kufanele ahlonyiswe ngemishini yokukhiqiza ethuthukisiwe kanye nohlelo oluqinile lokulawula ikhwalithi.
Amarekhodi Okulethwa Omlando
Ukuhlola ulwazi olufana nemijikelezo edlule yokulethwa komphakeli kanye nempendulo yekhwalithi yomkhiqizo kungasiza ukuqonda ukuzinza kokunikezwayo kwabo. Umhlinzeki ozinzile nothembekile angaqedela ukudiliva ngesikhathi kuyilapho eqinisekisa ikhwalithi.
Ukuhlaziywa Kwezinga Lekhwalithi Ye-Phenol
Amazinga Ekhwalithi Yamazwe Ngamazwe
Izinga le-USP liyindinganiso yekhwalithi yamazwe ngamazwe eyamukelwa kabanzi ye-phenol. Icacisa izinkomba ezifana nokuqukethwe kwe-phenol nokungcola ukuze kuqinisekiswe ukuthi imikhiqizo ihlangabezana nezidingo zemakethe yamazwe ngamazwe. Isitifiketi se-UL sigxile ekuphepheni komkhiqizo nasekuvikelweni kwemvelo, futhi sisebenza ezimakethe ezinezidingo eziqinile zemvelo.
Amazinga Ekhwalithi Kazwelonke
Ngokwezindinganiso zemboni yamakhemikhali yaseShayina, i-phenol kufanele ihambisane namazinga e-GB/T, okuhlanganisa nezimfuneko zokubukeka nezinkomba zekhwalithi. Ukucaciswa okufanelekile kufanele kulandelwe ngokuqinile ngesikhathi senqubo yokukhiqiza ukuze kuqinisekiswe ukuthi ikhwalithi yomkhiqizo ihlangabezana namazinga.
I-Phenol Procurement Skills
Ukusungula Uhlelo Olujwayelekile Lokuhlinzeka Ngempahla
Enqubweni yokuthengwa kwempahla, izingxoxo nabahlinzeki kufanele zenziwe ukuze kusungulwe uhlelo lokuhlola izinga elisezingeni. Cacisa izinto zokuhlola, amazinga okuhlola, ukuvama kokuhlolwa, njll., ukuze kuqinisekiswe ukungaguquguquki komkhiqizo. Sungula uhlelo lokuphathwa kwempahla ukuze ugweme ukulahlekelwa okubangelwa ukushintshashintsha kwekhwalithi.
Ukuhlela Okuphusile Kwezinhlelo Zokuthenga
Dala izinhlelo zokuthenga eziphusile ezisuselwe ezidingweni zokukhiqiza kanye nesimo sokusungula ukuze ugweme ukuma kokukhiqiza ngenxa yokuphazamiseka kochungechunge lokuhlinzeka. Gcina inani elifanele lesitoko sokuphepha ukuze ubhekane nezimo eziphuthumayo.
Ukuhlolwa Kwekhwalithi Okuvamile
Ngesikhathi senqubo yokuthengwa kwempahla, abahlinzeki kufanele kudingeke ukuthi bahlole ikhwalithi njalo futhi banikeze imibiko yokuhlola. Ngokuhlaziya idatha, thola izinkinga zekhwalithi ngesikhathi ukuze ugweme ukusetshenziswa kwemikhiqizo engafanelekile.
Ukucatshangelwa Kokuvikelwa Kwemvelo kanye Nokuthuthukiswa Okuqhubekayo
Izinto eziyingozi zingase zikhiqizwe ngesikhathi sokukhiqizwa kwe-phenol. Ngakho-ke, abahlinzeki kufanele bahambisane nemithetho yokuvikela imvelo ukuze banciphise ukungcoliswa kwenqubo yokukhiqiza. Ukukhetha abahlinzeki abanobungani bemvelo akukwazi nje ukuvikela imvelo kodwa futhi kunciphise izindleko zokusebenza.
Isiphetho
Ukukhetha abahlinzeki be-phenol kuyinqubo enezinhlangothi eziningi edinga ukunakwa kwezinkomba zezingxenyekazi zekhompuyutha ezifana neziqu zomphakeli, umthamo wokukhiqiza, namarekhodi omlando, kanye nezinkomba ezithambile ezifana namazinga ekhwalithi yomkhiqizo nemibiko yokuhlola. Ngokusungula uhlelo lokuphatha ikhwalithi olujwayelekile, ukuhlela ngokunengqondo inqubo yokuthengwa kwempahla, kanye nokwenza ukuhlolwa kwekhwalithi okuvamile, kungenzeka ukuqinisekisa ukuthi imikhiqizo ethengiwe ye-phenol ihlangabezana nezidingo zekhwalithi kuyilapho ihambisana nemvelo futhi iphephile. Abasebenzi embonini yamakhemikhali kufanele banamathisele ukubaluleka okukhulu ezindabeni zekhwalithi ekukhethweni kwabahlinzeki bempahla futhi benze izinqumo ezifanele kakhulu zokuthengwa kwempahla ngokusebenzisa izindlela zobungcweti nezesayensi.
