1. Ingozi Engathethiyo Kwindawo Yakho Yomsebenzi
“Ndakhohlela iiveki emva kokusika iikhawuntara zegranite,” ukhumbula uMiguel Hernandez, umzobi wamatye onamava eminyaka engama-22. “Ugqirha wam wandibonisa ii-X-ray – amanxeba amancinci emiphungeni yam yonke.”
Ibali likaMiguel aliqhelekanga.Uthuli lwe-silica oluyikristale– ekhutshwa xa kusikwa, kugaywa, okanye kugrunjwa amatye emveli – ihlelwa yi-WHO njengeI-carcinogen yeqela loku-1Izibalo ziyaxhalabisa:
•Izigidi ezi-2.3+ Abasebenzi baseMelika bayachaphazeleka minyaka le (OSHA)
•Amatyala amatsha e-silicosis angaphezu kwama-600uxilongwa minyaka le (CDC)
•Ixesha lokulibazisekaIimpawu ziyavela emva kweminyaka eli-10-30 yokubonakaliswa
I-paradox: Ilitye lendalo lixatyiswa ngenxa yokuqina, kodwa ukulisebenzisa kwalo kusongela kanye abantu abakha iindawo zethu.
2. Ukuphumelela: Isayensi Engasemva kwe-0 Silica Stone
Ngokungafaniyo nezinye iindlela "ezine-silica ephantsi" (ezihlala ziqulathe i-silica eyi-5-30%), yinyani0 Ilitye leSilicaisebenzisa iteknoloji ye-geopolymer:
Indlela Eyenziwe Ngayo
| Inyathelo | Ilitye Lendabuko | 0 Ilitye leSilica |
| Ukukhangela | I-granite/i-quartzite eqingqiweyo | Iidiphozithi zeeminerali ezikhethiweyo ezingenasilica (umz., i-nepheline syenite) |
| Ukubopha | Iibhondi zekristale zendalo | Isamente ye-geopolymer + ukuqinisa i-nano |
| Ingozi | I-silica ikhutshwa ngexesha lokusikwa | I-silica engenakuphefumula |
Utshintsho Oluphambili: Iifayibha ze-alumina ezinobukhulu obuncinci zithatha indawo yendima yesakhiwo se-silica, zifezekisa:
•Amandla oxinzelelo: 18,500 psi (xa kuthelekiswa ne-15,000 psi yegranite)
•Uzinzo lobushushu: Iyamelana nokutsha kwe--30°C ukuya kwi-150°C
•Ukufunxwa kwamanzi: <0.1% (ilungele iindawo ezimanzi)
3. Apho iZero Silica Stone iphumelela khona – Iiprojekthi zokwenyani
Ityala A: Ukuhlaziywa kweSibhedlele saBantwana (eSeattle)
"Besingenakubeka uthuli emngciphekweni kufutshane nomoya womoya we-ICU. Ii-silica slabs ezi-0 zisikiwe kwindawo ngeesarha ezimanzi ezisisiseko - akukho mfuneko yeetente zokuthintela."
– Inkokeli yeProjekthi, uLiora Chen
Iziphumo:
•Ufakelo olukhawulezileyo nge-22%ngokuchasene nelitye lemveli
•I-$14,500 igciniwekwiindleko zokucoca umoya
Ityala B: Umgangatho weSikhululo seenqwelo-moya ohamba ngezithuthi ezininzi (Ukwandiswa kweSitishi saseTokyo)
Emva kweenyanga ezili-18 zemithwalo emininzi:
| Izinto eziphathekayo | Ukunxiba okungaphezulu (mm) | Ukumelana namabala |
| Igranite | 0.8 | Umbala weoyile ophakathi |
| 0 Ilitye leSilica | 0.2 | Akukho ukungena (iimbobo ezivaliweyo) |
4. Ukuhlaziya iintsomi ezi-3
Intsomi 1: “Ukungabi nasilica kuthetha ubuthathaka.”
Inyaniso: Ukuqinisa i-nano kudalaiimatrices zekristale ezidibeneyo(ivavanywe elebhu ukuze ifumane ukuthotyelwa kwe-seismic zone 4).
Intsomi 2: “Ibonakala ngathi yinto yokwenziwa.”
Inyani: Ukulinganisa imithambo yendalo ngeukupeyinta i-oxide yeminerali– abakhi bezakhiwo bahlala beyiphambanisa nemarble yexabiso eliphezulu.
Intsomi 3: "Yeyangaphakathi kuphela."
Ubungqina: Isetyenziswa eBoston Harbor Boardwalk – imelana nokutshizwa ngetyuwa + ukuqanduselwa yiqhwa kunye nokujikeleza ngebhayisikile<0.03% ukwehla/ngonyaka.
5. Uhlalutyo lweendleko: Ixabiso lexesha elide kunexabiso lokuqala
Uhlalutyo lweprojekthi yorhwebo engama-10,000 sq.ft:
| Ixabiso leNdleko | Ilitye Lendabuko | 0 Ilitye leSilica |
| Izinto eziphathekayo | $42,000 | $48,000 |
| Ulawulo lothuli | $9,200 | $0 |
| I-PPE yabasebenzi | $3,800 | $800 (iimaski ezisisiseko) |
| I-inshurensi | $12,000 | $7,000(uvavanyo oluphantsi lweengozi) |
| Ulondolozo lweminyaka eli-10 | $28,500 | $6,000 |
| IYONKE | $95,500 | $61,800 |
"I-ROI ayisiyomali nje kuphela - iyindlela yokuziphatha. Akukho msebenzi ufanele atshintshise impilo yakhe ukuze afumane umvuzo."
– Elena Rodriguez, iSustainable Builders Alliance
6. Ukusebenzisa iZero Silica: Uluhlu lokutshekisha loMthengisi
Ukwamkelwa okungenamthungo:
1. Ukuhambelana kwezixhobo
•Isebenza ngeebhleyidi zedayimani eziqhelekileyo (akukho zixhobo zikhethekileyo)
•Ziphephe iibhithi ze-tungsten-carbide (zinokutshisa kakhulu i-matrix)
2. Iprotokholi yokuncamathelisa
•Sebenzisa iimortars ezisekelwe kwi-epoxy (ezilungele i-geopolymer)
•Icebiso Elilungileyo: Yongeza i-5% ye-silica fume ukuze ulungise ngokukhawuleza
3. Ulondolozo
•Coca ngezicoci ezingathathi cala ze-pH – izisombululo ze-asidi zonakalisa iibhondi ze-geopolymer kangangeminyaka emininzi
7. Ikamva: Ngaphaya kokuthobela imithetho
Imigaqo efana nomthetho we-OSHA ka-2016 we-silica (ukunciphisa ukuvezwa50 μg/m³) banyanzelisa ukwamkelwa. Kodwa iinkampani ezicinga ngekamva zisebenzisa0 Ilitye leSilicaye:
•Isiqinisekiso se-LEED: Ifumana Umgangatho Womoya Wangaphakathi + Iikhredithi Zobuchule
•Ukuthobela imithetho ye-B Corp: Ihambelana nemilinganiselo yokuphila kakuhle kwabasebenzi
•Umda woThengiso: Ama-74% abathengi bezorhwebo bahlawula iprimiyamu yezinto "ezingenabungozi eziqinisekisiweyo" (iNgxelo yeDatha yeDodge)
8. Inyathelo Lakho Elilandelayo
“Lo asingomveliso nje omnye – yindawo ephambili kushishino,” utshilo uGqr. Aris Thorne, isazinzulu sezinto ezisetyenziswayo eMIT. Vavanya amandla ayo:
Cela ikhithi yesampuluFumana amava ovavanyo lokumelana namabala
Fikelela kwiKhalkhuletha ye-ROI eyenziwe ngokwezifiso: Faka iinguqu zeprojekthi yakho
Bukela iDemo ekwindawo: Jonga ukusika ngaphandle kweenkqubo zokucoca umoya
Ingcinga Yokugqibela: Izakhiwo ezilungileyo azakhiwanga nje kuphela ukuze zihlale ixesha elide – zakhiwa ngentlonelo yesandla ngasinye esizibumbayo.
