Ukusukela ngoMeyi ka-2026, imakethi yehlabathi ye-diatomite powder ecociweyo enobunyulu obuphezulu ibona ukukhula okuzinzileyo, okuqhutywa yimfuno ekhulayo ngokukhawuleza yezixhobo zokucoca ezisebenza ngendlela yendalo, ezinekhabhoni ephantsi kunye ne-eco-friendly kulawulo lokusingqongileyo, ekulungisweni kokutya, kumacandelo okwakha nakwizolimo. Idatha yamva nje yeshishini ibonisa ukubaUkwanda kwe-7.1% unyaka nonyakakumthamo wemarike yehlabathi kwikota yokuqala ka-2026, kunye noqikelelo olubonisa ukuba ubungakanani bemarike iyonke buza kudlulaI-1.9 yezigidigidi zeerandi ngo-2031, ekhuthazwa kukuqiniswa kwemigangatho yokukhupha ukungcola kwendalo kwihlabathi liphela kunye nokungena ngokukhawuleza kwezixhobo zokwakha ezilungele indalo.

▲Unyango lwaManzi kunye noLawulo lokusingqongileyo

Icandelo lokunyanga amanzi kunye nolawulo lokusingqongileyo lihlala liyi-imakethi enkulu yabasebenzisi bokugqibela, ebangela ngaphezulu kwama-42% emfuno iyonke yehlabathi, apho umgubo we-diatomite ocutshungulwayo uxatyiswa kakhulu ngenxa yesakhiwo sawo esikhethekileyo seembobo ezincinci, amandla awo okufaka amanzi amdaka aqinileyo, ukungangeni kakuhle kweekhemikhali kunye nendawo enkulu yomphezulu. Isetyenziswa kakhulu njengendawo yokucoca eyintloko kunyango lwesinyithi esinzima semizi-mveliso, ukucoca amanzi okusela kunye nokuhluzwa kwegesi yenkunkuma yemizi-mveliso, enokufunxa ngokufanelekileyo izinto eziqinileyo ezixhonyiweyo, ii-ion zesinyithi esinzima eziseleyo kunye neemolekyuli zevumba elingaqhelekanga, ngelixa igcina ukusebenza kakuhle kokucoca phantsi kweemeko zobushushu obuphezulu kunye nokubola. Imfuno ekhulayo yonyango lwamanzi acocekileyo eMntla Melika, kwiManyano yaseYurophu nakwiMpuma Asia ikhawulezise kakhulu ukungena kwemarike, ngakumbi kwiiprojekthi zokuphucula amdaka kamasipala kunye nezibonelelo zonyango lwenkunkuma eyingozi kwimizi-mveliso.

◆Ukulungiswa kokutya neziselo

Kwishishini lokucubungula ukutya neziselo, umgubo we-diatomite ococekileyo kakhulu usetyenziswa kakhulu kwi-ukuhluzwa kwebhiya, ukucaciswa kwejusi yeziqhamo kunye nokususwa kombala kwioyile etyiwayongenxa yokwakheka kwayo kwendalo okungenatyhefu, ukungena kakuhle kwamanzi kwaye akukho kuphazamiseka kwincasa yemveliso. Ulwakhiwo lwayo olunemingxuma lunokuthintela ngokufanelekileyo ukungcola okuxhonyiweyo kunye neentsalela zemvubelo, ngelixa lugcina incasa yokuqala kunye nezithako zesondlo zeemveliso, ezihambelana ngokupheleleyoImigangatho yokhuseleko lokutya ye-FDA kunye ne-GB 2760, kwaye iqatshelwa njengoncedo lokuhluza lwendalo olukhuselekileyo nolusebenzayo lishishini lokucubungula ukutya kwihlabathi liphela.

■Isakhiwo Esiluhlaza kunye nezixhobo ezisebenzayo

Kwicandelo lezinto zokwakha eziluhlaza nezisebenzayo, isikali sokusetyenziswa kwe-modified diatomite powder sikhula ngokukhawuleza. Abaphuhlisi bezinto zokwakha abaninzi bayidibanisa neengubo zokususa i-formaldehyde zangaphakathi, izixhobo zodonga zokuhombisa udaka lwe-diatom kunye neepaneli zokucoca umoya ngenxa yokufunxa kwayo okuqhubekekayo kwendalo kunye nokukwazi kwayo ukubola kwiikhompawundi ze-organic eziguquguqukayo zangaphakathi (ii-VOC), ukufuma kwangaphakathi okuhlengahlengiswayo kunye nokungalali komlilo wendalo.

★Uphuhliso lweTekhnoloji kunye noPhuculo lweeMveliso

Ubuchule bobuchwepheshe buphucula rhoqo inkqubo yemveliso yemizi-mveliso. Isizukulwana esitsha seumgubo we-diatomite oguquliweyo osebenza kakuhle kakhuluIngene kwimarike, inomlinganiselo ophakathi wobukhulu beembobo ezilawulwa ngaphakathi0.1–1μm, indawo ethile yomphezulu phezu65m²/g, kunye nonyango lokuvuselela ubushushu bomphezulu, oluphucula kakhulu amandla okufunxa kunye namandla okulayisha ukungcola xa kuthelekiswa neemveliso zemveli.

○Uzinzo njengoMqhubi woKhulo oluPhambili

Uzinzo yeyona nto iphambili eqhuba ukukhula kwemarike. Ngokungafaniyo nezixhobo zokwenziwa ezixhomekeke ekuhlanganisweni kweekhemikhali ezinamandla aphezulu, i-diatomite yi-ilitye lendalo elithambileyo le-siliceous sedimentaryyenziwe kukuqokelelwa kweentsalela ze-diatom, ezifuna kuphela ukucocwa ngokomzimba, ukucocwa kobushushu obuphantsi kunye nokulungiswa kokusila, kunyeukukhutshwa kwekhabhoni okuphantsi kakhulukuyo yonke inkqubo yemveliso.

Okwangoku, kuphelileAma-77% amashishini emveliso aphambili kushishinoBasebenzise ulawulo lwemigodi eluhlaza, iteknoloji yokuvuselela ukonga amandla kunye neenkqubo zokusetyenziswa okubanzi kwe-tailings, nto leyo enciphisa kakhulu impembelelo yenkqubo yemveliso kwindalo esingqongileyo.

▶Ukuvuthwa kweCandelo loNikezelo lweHlabathi

Ukuvuthwa kwenkqubo yokubonelela ngeenkonzo kwihlabathi jikelele kuphucuke kakhulu kwiminyaka yakutshanje. Amashishini amakhulu andise ukuhlanganiswa ngokuthe nkqo ukusuka ekuhlolweni kwezimbiwa ezingavuthwanga ukuya ekucutshungulweni okunzulu kweemveliso eziguquliweyo ezigqityiweyo, kwaye bakhe amaziko okucubungula nokuhambisa kwiindawo ezifunwa kakhulu ezifanaITshayina, uMntla Melika kunye neNtshona Yurophu, nto leyo eye yanciphisa ngempumelelo umjikelo wokunikezelwa kwemveliso.

Ngenxa yoko, amashishini aphambili andisa utyalo-mali kwiiinkqubo zokuhlola ezikrelekrele nezinemigangatho, uphando nophuhliso lwetekhnoloji yokuguqula umphezulu, kunye neenkqubo zokulandelela umgangatho wedijithali, ukuzinzisa umgangatho wemveliso kunye nokunciphisa iindleko zokusebenza ezipheleleyo.

●Imbono yoMhlalutyi weShishini

Abahlalutyi beshishini babonise ukuba uphuhliso olunzulu lwentsebenziswano phakathi kwamashishini okucubungula izimbiwa, amaziko ophando lwezinto ezisingqongileyo kunye namashishini okufaka izicelo zesiphelo esisezantsi kuya kuba sisitshixo sokuvula indawo entsha yokukhula kweshishini. Iimeko zezicelo ezivelayo ziquka iinkalo ezintathu ezibalulekileyo:

Ngenxa yayoiimpawu zokhuseleko lwendalo, ukusebenza kakuhle kokufunxa kunye namathuba amaninzi okusetyenziswa, imakethi ye-diatomite powder ecociweyo enobunyulu obuphezulu iya kugcina ukukhula okuzinzileyo kwixesha elizayo, ibe yinto ebalulekileyo nengabizi kakhulu kwindalo esingqongileyo ekutshintsheni kwehlabathi ukuya kukhuseleko lwendalo olunekhabhoni ephantsi kunye nophuhliso oluzinzileyo olusempilweni.
