Ukusetshenziswa kodayi kwenza izimpilo zabantu zibe nemibala egqamile.

Kusukela ezingutsheni ezisemzimbeni, isikhwama sesikole esingemuva, njengesikhafu sokuhlobisa, ithayi, esivame ukusetshenziswa ezindwangu ezilukiwe, izindwangu ezilukiwe kanye nemikhiqizo yefayibha, sizidaya ngemibala ebomvu, ephuzi, onsomi kanye neluhlaza okwesibhakabhaka.
Empeleni, njengenhlanganisela yezinto eziphilayo, udayi, esimweni sawo sama-molecule noma esihlakazekile, unikeza ezinye izinto umbala ogqamile noqinile.

Empeleni, amadayi ahlakazekile awuhlobo lwamadayi angewona ama-ionic anokuncibilika kwamanzi okuphansi.

Isakhiwo sayo sama-molecule silula, ukuncibilika kwayo kuphansi, ukuze ikwazi ukusabalala kahle esixazululweni, ngaphezu kokuyigaya ibe ngaphansi kwama-micron amabili, kudingeka futhi kufakwe ama-dispersant amaningi, ukuze ikwazi ukusabalala esixazululweni kancane kancane. Ngakho-ke, lolu hlobo lwedayi lwaziwa kabanzi ngokuthi “idayi yokuhlakaza”.

Ingahlukaniswa cishe ibe yi-orenji ehlakazekile, ephuzi ehlakazekile, eluhlaza okwesibhakabhaka ehlakazekile, ebomvu ehlakazekile njalo njalo, imibala eminingana ngokuhambisana nezilinganiso ezahlukene, ingathola nemibala eminingi. Uma kuqhathaniswa neminye imibala, amadayi ahlakazekile yiwona asetshenziswa kakhulu futhi angomunye wamadayi abaluleke kakhulu.

Ngenxa yokusetshenziswa kabanzi kwamadayi asakazekile, ukuguquguquka kwentengo yezinto zokusetshenziswa kanye nemikhiqizo yayo kuthinta nokulungiswa okusheshayo kwentengo yamasheya ezinkampani ezifanele ezisohlwini.

NgoMashi 21, 2019, kwenzeka ukuqhuma e-xiangshui Chenjiagang Tianjiayi Chemical Factory eYancheng. IKomidi Eliphakathi le-CPC kanye noMkhandlu Kahulumeni banikeze ukubaluleka okukhulu kulokhu kuqhuma. Isifundazwe saseJiangsu kanye neminyango efanele benza konke okusemandleni abo ukusindisa nokusindisa abantu abavela kuzo zonke izigaba zokuphila bathandazela i-Xiangshui.

Ngemva kokuqhuma, amapaki ezimboni zamakhemikhali ezweni lonke aqala imisebenzi yokuhlola ukuphepha esimweni esiphuthumayo. IShaoxing Shangyu, idolobha elikhulu lokukhiqiza udayi, nayo iqale ukuhlolwa kokuphepha esifundeni sonke, okuzokhuthaza amabhizinisi amakhemikhali ezweni lonke ukuthi ashaye i-alamu futhi kumele asebenze ngokuphepha.

Imikhiqizo eyinhloko yesitshalo samakhemikhali ihlanganisa amadayi ahlakazekile kanye namanye amadayi asabelayo, amadayi aqondile aphakathi - i-m-phenylenediamine.

Ngemva kokuqhuma, amabhizinisi ahlukahlukene odayi abasabalalisa kanye nabakhiqizi abaphakathi baye bayeka ukwamukela ama-oda, okuholele ngqo ekushodeni kokunikezwa kwe-m-phenylenediamine, okuzokhuphula intengo yemikhiqizo yodayi abasabalalisa engezansi.

Intengo yemakethe ye-m-phenylenediamine isiphindwe kabili kusukela ngoMashi 24, futhi inhlanganisela yokuntuleka kwamasheya kanye nokwehla kwamandla okukhiqiza kuzonyusa amanani edayi asakazekile.
Futhi izinkampani ezimbalwa zasekhaya ezibhalwe ohlwini lwedayi ehlukanisiwe zabelana ngamanani akhuphukile futhi ehlile, akunzima ukukuqonda. Kodwa ukuguquguquka kwamadayi ehlukanisiwe akuyona into eyenzeka ngokungahleliwe eminyakeni yamuva nje, futhi abantu bebelokhu beqaphela ukuguquguquka kwentengo yesitoko sayo.

➤ Ngokombono wokuncintisana emakethe, imakethe yedayi ehlakazekile iye yakha kancane kancane isimo sokuncintisana emakethe ye-oligopoly, kuyilapho isidingo samadayi ahlakazekile sizinzile. Ukwanda kokuhlushwa kwemakethe yedayi ehlakazekile kuzothinta ukunikezwa kwemakethe kanye nesidingo, kuthuthukise amandla okuxoxisana kwabathengisi, bese kukhuthaza ukwenyuka kwentengo yemakethe yedayi ehlakazekile.

Ngo-2018, ukusebenza kwezinkampani ezisohlwini ezinedayi ezisabalele kwakungcono, futhi ngo-2019, uma ukusebenza kuqhubeka nokukhula, ukwenyuka kwentengo yomkhiqizo kuyisilinganiso esiqondile nesisebenza kahle kakhulu.

Ngakolunye uhlangothi, ngenxa yokuvikelwa kwemvelo kuqala, lokhu kuzoholela nasekusabalaleni kwemikhiqizo, amanani odayi azoqhubeka nokusebenza kahle. Akuzona nje izindleko zokuphathwa kokuvikelwa kwemvelo ezikhuphukayo, njengokulungiswa njalo komkhawulo wokukhiqiza okuzothinta ukunikezwa kwemakethe yodayi osabalalayo.

Nakuba amanye amabhizinisi odayi asakazekile ake amisa ukukhiqizwa azoqhubeka kancane kancane nokukhiqizwa, kuvame kakhulu ukuthi umkhiqizo wangempela wamabhizinisi okukhiqiza ube mncane kakhulu kunalowo wangaphambi kokuba ukukhiqizwa kumiswe.

Impi enzima yokulwa nokungcola izophoqa izimboni eziningi ezinamandla amakhulu ukuba ziqede, kanti imboni yodayi isenendlela ende okufanele iyihambe.
