Izinselelo Zokuklama Izisetshenziswa Zedivayisi Yezokwelapha

Abahlinzeki bempahla banamuhla banenselelo yokwenza izinto ezihlangabezana nezidingo zenkundla yezokwelapha ethuthukayo.Embonini ethuthukayo, amapulasitiki asetshenziswa emishinini yezokwelapha kufanele akwazi ukumelana nokushisa, izinto zokuhlanza, nezibulala-magciwane, kanye nokuguga azokuthola nsuku zonke.Abakhiqizi bemishini yoqobo (ama-OEMs) kufanele bacabangele amapulasitiki angenayo i-halogen, futhi iminikelo e-opaque kufanele ibe nzima, ivale amalangabi, futhi itholakale ngemibala eminingi.Nakuba zonke lezi zimfanelo kufanele zicatshangelwe, kuyadingeka futhi ukugcina ukuphepha kwesiguli kuseqophelweni eliphezulu.

Challenges

Ukudlulela esibhedlela
Amapulasitiki akudala ayeklanyelwe ukumelana nokushisa asheshe athola indawo emhlabeni wezokwelapha, lapho futhi kunesidingo sokuthi amadivaysi aqine futhi athembeke.Njengoba amapulasitiki amaningi engena endaweni yesibhedlela, kwavela imfuneko entsha yamapulasitiki ezokwelapha: ukumelana namakhemikhali.Lezi zinto bezisetshenziswa emishinini eyenzelwe ukuphatha izidakamizwa ezinokhahlo, njengalezo ezisetshenziswa ekwelashweni kwe-oncology.Amadivayisi ayedinga ukumelana namakhemikhali ukuze kugcinwe ukuqina kanye nobuqotho besakhiwo ngaso sonke isikhathi lapho umuthi usetshenziswa.

Izwe Elinzima Lokubulala Amagciwane
Esinye isimo sokungazweli ngamakhemikhali size ngendlela yezibulala-magciwane ezinamandla ezisetshenziselwa ukulwa nezifo ezitholwa esibhedlela (i-HAIs).Amakhemikhali aqinile kulawa ma-disinfectants angenza amapulasitiki athile abe buthaka ngokuhamba kwesikhathi, awashiye engaphephile futhi engafanele umhlaba wezokwelapha.Ukuthola izinto ezimelana namakhemikhali kube umsebenzi okhulayo onzima kuma-OEM, njengoba izibhedlela zibhekana nemithethonqubo eyengeziwe yokuqeda ama-HAI.Izisebenzi zezokwelapha nazo zibulala amagciwane emishinini ngokuvamile ukuze ilungele ukusetshenziswa, okulimaza kakhulu ukuqina kwemishini yezokwelapha.Lokhu angeke kunganakwa;ukuphepha kwesiguli kubaluleke kakhulu futhi imishini ehlanzekile iyisidingo, ngakho-ke amapulasitiki asetshenziswa ezindaweni zezokwelapha kufanele akwazi ukumelana nokubulawa amagciwane njalo.

Njengoba izibulala-magciwane ziba namandla futhi zisetshenziswa kaningi, isidingo sokuthuthukisa ukumelana namakhemikhali ezintweni ezisetshenziselwa ukuthuthukisa imishini yezokwelapha siyaqhubeka sikhula.Ngeshwa, akuzona zonke izinto ezikwazi ukumelana namakhemikhali okwanele, kodwa zidayiswa njengokungathi zikhona.Lokhu kuholela ekucacisweni kwezinto ezibonakalayo okuholela ekuqineni okungekuhle kanye nokuthembeka kudivayisi yokugcina.

Ngaphezu kwalokho, abaklami bemishini badinga ukuhlolisisa kangcono idatha yokumelana namakhemikhali abethulwa yona.Ukuhlolwa kokucwiliswa kwesikhathi esilinganiselwe akubonisi ngokunembile ukuvala inzalo okuvamile okwenziwa ngenkathi kusevini.Ngakho-ke, kubalulekile ukuthi abahlinzeki bezinto ezibonakalayo bahlale begxile kukho konke okubalulekile kwedivayisi lapho benza into engamelana nezibulala-magciwane.

I-Halogenated Materials in Recycling
Esikhathini lapho abathengi bekhathazeke ngokuthi yini engena emikhiqizweni yabo-futhi iziguli zasesibhedlela ziya ngokuya ziqaphela amapulasitiki asetshenziswa phakathi nezinqubo zezokwelapha-ama-OEM adinga ukucabangela ukuthi yiziphi izinto zabo ezenziwe.Isibonelo esisodwa yi-bisphenol A (BPA).Njengoba kunemakethe yamapulasitiki angenayo i-BPA embonini yezokwelapha, kunesidingo esikhulayo samapulasitiki angenawo ama-halogenated.

Ama-halogen afana ne-bromine, i-fluorine, ne-chlorine asebenza kakhulu futhi angaholela emiphumeleni emibi yemvelo.Lapho izinto zezokwelapha ezenziwe ngezinto zepulasitiki eziqukethe lezi zakhi zingagaywa kabusha noma zilahlwe ngendlela efanele, kunengozi yokuthi ama-halogen akhishelwe endaweni ezungezile futhi ahlangane nezinye izinto.Kunokukhathazeka ngokuthi izinto zepulasitiki ezine-halogenated zizokhipha amagesi abolayo kanye anobuthi emlilweni.Lezi zakhi kufanele zigwenywe kumapulasitiki ezokwelapha, ukunciphisa ingozi yomlilo kanye nemiphumela emibi yemvelo.

Uthingo Lwezinto
Esikhathini esedlule, amapulasitiki angenayo i-BPA ayecace kakhulu, futhi udayi wawumane wengezwe ukuze uthayiphe umsebenzi lapho ufaka uphawu noma ufaka umbala njengoba iceliwe yi-OEM.Manje, kunesidingo esandayo samapulasitiki akhanyayo, njengalawo aklanyelwe ukufaka izintambo zikagesi.Abahlinzeki bezinto ezibonakalayo abasebenza ngamakesi ezindlu ngocingo kudingeka baqinisekise ukuthi abanqamuki ilangabi, ukuze bavikele imililo kagesi uma kunezintambo ezingalungile.

Kwelinye inothi, ama-OEM adala lawa madivayisi anezinketho zombala ezihlukile ezingabelwa amabhrendi athile noma ngezinjongo zobuhle.Ngenxa yalokhu, abahlinzeki bezinto ezibonakalayo kudingeka baqinisekise ukuthi benza izinto ezingasetshenziswa ukuthuthukisa izinsiza zezokwelapha ngemibala eqondile efunwa amabhrendi, kuyilapho kucutshungulwa ingxenye eshiwo ngaphambili yokunqanda ilangabi, kanye nokumelana namakhemikhali nokubulala inzalo.

Abahlinzeki bezinto ezibonakalayo banokuningi okufanele bakukhumbule lapho benza umnikelo omusha ozomelana nezibulala-magciwane ezinokhahlo nezindlela zokuvala inzalo.Badinga ukuhlinzeka ngezinto ezizohlangabezana nezindinganiso ze-OEM, kungakhathaliseki ukuthi ngamakhemikhali angeziwe noma angangezwanga, noma umbala wedivayisi.Nakuba lezi kuyizici ezibalulekile okufanele zicatshangelwe, ngaphezu kwakho konke, abahlinzeki bempahla kufanele benze ukukhetha okuzogcina iziguli zasesibhedlela ziphephile.
