Izinkomishi zepulasitiki ziyisitsha esilahlwayo esisetshenziswa kakhulu esingabonwa ngezikhathi ezihlukahlukene. Nakuba kulula ukuzisebenzisa izinkomishi zepulasitiki, ikhwalithi yazo iyisihloko esithinteka kakhulu. Ukuqinisekisa izinga lezinkomishi zepulasitiki, sidinga ukuqhuba aukuhlola okuphelele. Nazi ezinye izethulo zezinto zokuhlola izinga lezinkomishi zepulasitiki.
1, Izidingo zezinzwa
Izidingo zezinzwa ziyisinyathelo sokuqala sokuhlolwa kwekhwalithi yezinkomishi zepulasitiki. Izidingo zezinzwa zifaka ukushelela, ukufana kombala, ukucaca kokuphrinta, ukuma kwenkomishi, nokuvala indawo yangaphandle yenkomishi. Nakuba lezi zici zingase zibonakale zilula, empeleni zibaluleke kakhulu. Isibonelo, ukushelela kwendawo yangaphandle yendebe kungathinta ubunzima bayo bokuhlanza kanye nekhwalithi yokubukeka, kuyilapho ukubekwa uphawu kwendebe kuthinta ukusebenza kwayo ngesikhathi sokusetshenziswa.
2, Ivolumu yokuthutha isiyonke
Isamba senani lokufuduka libhekisela enanini lamakhemikhali emikhiqizweni yepulasitiki angase athuthele ekudleni lapho ethintana nawo. Leli nani lokufuduka liyinkomba ebalulekile yokuhlola ikhwalithi yezinkomishi zepulasitiki. Uma umthamo wokufuduka mkhulu kakhulu, ungaba nomthelela empilweni yomuntu. Ngakho-ke, ekuhlolweni kwekhwalithi yezinkomishi zepulasitiki, inani eliphelele lokufuduka liyinto ebaluleke kakhulu yokuhlola.
3, ukusetshenziswa kwe-potassium permanganate
Ukusetshenziswa kwe-potassium permanganate kusho inani lokusabela phakathi kwenkomishi yepulasitiki ne-potassium permanganate ngaphansi kwezimo ezithile. Le nkomba ingabonisa ukuthi kungenzeka ukubola kwezinto eziphilayo ezinkomishini zepulasitiki. Uma ukusetshenziswa kwe-potassium permanganate kuphezulu kakhulu, kusho ukuthi ukusebenza kwenhlanzeko kwezinkomishi zepulasitiki kubi, okungase kuthinte ikhwalithi nokuhlanzeka kokudla.
4. Izinsimbi ezinzima
Izinsimbi ezisindayo zibhekisela ezintweni zensimbi ezinokuminyana okukhulu kuno-4.5g/cm3. Ekuhlolweni kwekhwalithi yezinkomishi zepulasitiki, izinsimbi ezinzima zidinga ukuhlolwa ukuze kuqinisekiswe ukuthi azinawo umthelela empilweni yomuntu. Uma insimbi esindayo ezinkomishini zepulasitiki iphezulu kakhulu, ingase imuncwe umzimba womuntu, kube yingozi empilweni.
5,Ukuhlolwa kwe-Decolorization
Ukuhlolwa kwe-decolorization kuyindlela yokuhlola ukuzinza kombala wezinkomishi zepulasitiki ngaphansi kwezimo ezihlukene. Lokhu kuhlola kuhilela ukuveza inkomishi ezimeni ezihlukahlukene nokubheka izinguquko zayo zombala. Uma umbala wenkomishi ushintsha kakhulu, kusho ukuthi ukuqina kombala wayo akukuhle, okungase kuphazamise ubuhle bendebe.
6,Ezinye izinto zokuhlola
Ngaphezu kwalezi zinto zokuhlola ezingenhla, kukhona nezinye izinto zokuhlola, njengengqikithi ethile yokufuduka kwamapulasitiki e-phthalic, inani elithile lokufuduka kwe-caprolactam, inani elithile lokufuduka le-polyethylene, inani elithile lokufuduka kwe-terephthalic acid, ingqikithi ethile yokufuduka. isamba sokufuduka kwe-ethylene glycol, kanye nengqikithi ethile yokufuduka kwe-antimony. Lezi zinto zokuhlola zingasisiza ukuthi sithole ukuqonda okuphelele kwezinto zamakhemikhali ezinkomishini zepulasitiki, ngaleyo ndlela kuvikelwe kangcono impilo yabantu nokuphepha kwemvelo.
Izinkomishi zepulasitiki seziyinketho ethandwayo kubantu abaningi, ikakhulukazi abafundi nabasebenzi basehhovisi, ngenxa yokukhanya kwabo nokuqina. Kodwa-ke, ukukhetha inkomishi yepulasitiki efanelekile nakho kudinga amakhono. Nazi ezinye izindlela zokukhetha izinkomishi zepulasitiki ukuze zisetshenziswe:
Material: Impahla yenkomishi yepulasitiki ibaluleke kakhulu. Akunconywa ukukhetha izinkomishi zepulasitiki ezenziwe ngezinto ze-PC ngoba zijwayele ukukhulula i-bisphenol A, eyingozi empilweni. Izinkomishi zepulasitiki ezenziwe ngezinto ezifana ne-Tritan, PP, PCT, njll.
Ukuqina: Ukuqina kwezinkomishi zepulasitiki kungazwakala ngesandla. Uma inkomishi yepulasitiki izwakala ithambile futhi ukushuba akwanele, ungawukhethi. Izinkomishi zepulasitiki ezingcono zenziwe ngezinto eziwugqinsi, ezizwakala zijiyile uma zimpintshwa ngesandla.
Iphunga: Ngaphambi kokuthenga inkomishi yepulasitiki, ungakwazi ukuhogela iphunga lenkomishi yepulasitiki kuqala. Uma inkomishi yepulasitiki inephunga elimnandi, ungayithengi.
Ukubukeka: Lapho ukhetha indebe yepulasitiki, kubalulekile ukunaka ukubukeka kwayo. Okokuqala, hlola umbala wenkomishi yepulasitiki. Ungathengi izinkomishi zepulasitiki ezinemibala egqamile. Okwesibili, bheka ukuthi akukho yini ukungcola enkomishini yepulasitiki. Okwesithathu, hlola ukuthi inkomishi yepulasitiki ibushelelezi yini.
Umkhiqizo: Uma uthenga izinkomishi zepulasitiki, kungcono ukhethe abakhiqizi abanegama elihle lomkhiqizo wekhwalithi eqinisekisiwe.
Okokugcina, ngithanda ukukhumbuza wonke umuntu ukuthi kungakhathaliseki ukuthi hlobo luni lwenkomishi yepulasitiki abayikhethayo, badinga ukunaka indlela yokusetshenziswa ukuze bagweme izinkinga zempilo ezibangelwa ukusetshenziswa okungalungile. Isibonelo, ungakugcini ukudla okune-asidi noma okunamafutha isikhathi eside.
