Iikhawuntara zamatye ezingenasilica zisusa umngcipheko wokuchatshazelwa yikristale ye-silica ngexesha lokwenziwa nokufakelwa, nto leyo eyenza ukuba zibe lukhetho olukhuselekileyo kwiindawo zangaphakathi kunye nempilo yabasebenzi. Olu hlalutyo luhlola impembelelo yempilo, ukwakheka kwezinto, kunye nokuqwalaselwa okusebenzayo kwemiphezulu yamatye eyenziwe nge-silica.
Izinto ezibalulekileyo ekufuneka ziqwalaselwe
- Ukuvezwa kwe-crystalline silica kubangela i-silicosis, umhlaza wemiphunga, kunye nesifo sezintso ngokwemigangatho yezempilo yomsebenzi ye-OSHA
- Iikhawuntara zeZero-silica ziqulathe i-0% ye-crystalline silica xa kuthelekiswa ne-30-50% kwiindawo ze-quartz zemveli
- Iindlela ezingasetyenziswayo ze-silica zifikelela kwi-90-95% yemilinganiselo yokuqina kwe-quartz yendabuko
- Imakethi yeekhawuntara zehlabathi ezingenasilica ifikelele kwi-$2.3 yeebhiliyoni ngo-2025, ikhula nge-28% ngonyaka
- ICalifornia neNew York ziqalise ukuvalwa kwelitye elenziwe nge-silica ephezulu kuzwelonke
Zithini iiCountertops zeSilica Free Stone?
Iikhawuntara zamatye ezingenasilica ziindawo ezakhiwe ngobuchule ezenziwe ngaphandle komxholo we-silica ekristale. Ilitye elenziwe ngobuchule bemveli liqulathe i-silica ekristale engama-30-50% edityaniswe ne-polymer resins. Ezinye iindlela ze-Zero-silica zithatha indawo ye-silica ngezithako zeminerali ezizezinye ezifana neglasi ephinde yasetyenziswa, i-porcelain, i-feldspar, okanye i-calcium carbonate.
Umahluko ophambili kwi-quartz yendabuko: Iindawo ezingenayo i-silica zisusa uthuli lwe-silica oluphefumulayo ngexesha lokusika, ukugaya, kunye nokusebenza kokupolisha. Lo mahluko ujongana neengxaki zempilo ezikhulayo phakathi kwabasebenzi bokuvelisa kunye nabanini bezindlu.
Inkqubo yokuvelisa ilitye elingena-silica ilandela iindlela ezifanayo zokucinezela nokunyanga njengelitye eliyilwe ngendlela yendabuko. Ukuxinana kokungcangcazela kwe-vacuum kudala iindawo ezingenamibhobho ezineempawu ezifanayo zoxinano kunye nobunzima.
Iingozi zeMpilo zoKuchaphazeleka yiCrystalline Silica
Iingozi zeMpilo emsebenzini
Uthuli lwe-silica oluyikristale lubeka iingozi ezinkulu kwimpilo xa luphefumlwa. I-International Agency for Research on Cancer (IARC) ibeka i-silica eyikristale njenge-carcinogen yeQela loku-1. Iziphumo zempilo ziquka:
- I-Silicosis: Amanxeba angapheliyo emiphungeni abangela ubunzima bokuphefumla
- Umhlaza wemiphunga: Umngcipheko okhulayo uhambelana nexesha lokuvezwa
- Isifo semiphunga esingapheliyo (i-COPD): Ukunqongophala komoya oqhubekayo
- Isifo sezintso: Iingxaki zokuzikhusela komzimba ezivela kumasuntswana esilica
IZiko loLawulo lweZifo kunye nokuThintela (i-CDC) libika ukuba iimeko ze-silicosis phakathi kwabasebenzi abenza amatye zinyuke ngama-800% phakathi kowama-2010 nowama-2023. Oku kwanda kuhambelana nokuthandwa okukhulayo kweekhawuntara zamatye ezenziwe nge-silica ephezulu.
