1. Kev Phom Sij Uas Tsis Muaj Suab Nrov Ntawm Koj Qhov Chaw Ua Haujlwm
"Kuv hnoos tau ntau lub lis piam tom qab txiav cov granite countertops," Miguel Hernandez, tus kws txiav pob zeb uas muaj 22 xyoo kev paub dhau los, hais. "Kuv tus kws kho mob tau qhia kuv cov duab X-ray - cov qhov txhab me me thoob plaws kuv lub ntsws."
Zaj dab neeg ntawm Miguel tsis yog ib qho tsis tshua muaj.Cov hmoov av crystalline silica- tso tawm thaum txiav, sib tsoo, lossis khawb pob zeb ib txwm muaj - yog WHO cais ua ib qhoPawg 1 carcinogenCov ntaub ntawv no ua rau kuv xav tsis thoob:
•2.3 lab+ Cov neeg ua haujlwm Asmeskas raug kev txom nyem txhua xyoo (OSHA)
•Muaj ntau tshaj 600 tus neeg mob silicosis tshiabkuaj mob txhua xyoo (CDC)
•Lub sijhawm qeebCov tsos mob tshwm sim tom qab 10-30 xyoo ntawm kev raug tshuaj
Qhov kev xav tsis thoobPob zeb ntuj muaj nqis rau qhov ruaj khov, tab sis nws cov txheej txheem ua rau muaj kev hem thawj rau cov neeg uas tsim peb qhov chaw.
2. Kev Tshawb Fawb Tshiab: Kev Tshawb Fawb Tom Qab Pob Zeb Silica 0
Tsis zoo li lwm txoj hauv kev "low-silica" (feem ntau muaj 5-30% silica), muaj tseeb0 Pob Zeb Silicasiv cov thev naus laus zis geopolymer:
Yuav Ua Li Cas
| Kauj Ruam | Pob Zeb Ib Txwm | 0 Pob Zeb Silica |
| Kev yuav khoom | Granite / Quartzite uas tau khawb av | Cov chaw muaj cov pob zeb tsis muaj silica (piv txwv li, nepheline syenite) |
| Kev khi | Cov pob zeb crystalline ntuj | Geopolymer cement + nano-reinforcement |
| Kev phom sij | Silica tawm thaum lub sijhawm txiav | Tsis muaj silica uas ua pa tau |
Kev Tsim Kho Tshiab Tseem Ceeb: Cov fibers alumina me me uas muaj nano hloov silica lub luag haujlwm ntawm cov qauv, ua tiav:
•Lub zog compressive: 18,500 psi (piv rau granite 15,000 psi)
•Kev Ruaj Ntseg ThermalTiv taus kev tawg ntawm -30 ° C txog 150 ° C
•Kev Nqus Dej: <0.1% (zoo tagnrho rau thaj chaw ntub dej)
3. Qhov twg Zero Silica Pob Zeb Ua Tau Zoo Dua - Cov Haujlwm Tiag Tiag
Rooj Plaub A: Kev Kho Dua Tsev Kho Mob Menyuam Yaus (Seattle)
"Peb tsis tuaj yeem pheej hmoo hmoov av ze ntawm qhov cua ntawm ICU. 0 Cov pob zeb silica tau txiav rau ntawm qhov chaw nrog cov tshuab txiav ntub yooj yim - tsis tas yuav muaj cov tsev pheeb suab kaw."
– Tus Thawj Coj Haujlwm, Liora Chen
Cov txiaj ntsig:
•Kev teeb tsa sai dua 22%piv rau pob zeb ib txwm muaj
•$14,500 txuag tauntawm cov nqi lim cua
Rooj Plaub B: Pem Teb Tshav Dav Hlau Muaj Neeg Tuaj Ntau (Kev Nthuav Dav ntawm Chaw Nres Nkoj Tokyo)
Tom qab 18 lub hlis ntawm kev thauj khoom ntau heev:
| Khoom siv | Kev Hnav Nto (hli) | Kev Tiv Thaiv Xim |
| Pob zeb granite | 0.8 | Xim roj nruab nrab |
| 0 Pob Zeb Silica | 0.2 | Tsis muaj qhov nkag mus (qhov pores kaw) |
4. Kev Tshawb Pom 3 Yam Dab Neeg
Dab Neeg 1"Tsis muaj Silica txhais tau tias tsis muaj zog."
Qhov tseeb: Nano-reinforcement tsimcov crystal matrix sib txuas(kuaj hauv chaw kuaj mob kom ua raws li thaj tsam av qeeg 4).
Dab Neeg 2"Nws zoo li dag."
Kev muaj tiag: Ua raws li cov kab ntawm cov leeg nqaijcov qauv ntawm cov pob zeb oxide– cov kws kes duab vajtse feem ntau yuam kev nws rau cov pob zeb zoo tshaj plaws.
Dab Neeg 3: "Tsuas yog rau sab hauv xwb."
Pov thawjSiv rau hauv Boston Harbor Boardwalk - tiv taus cov tshuaj tsuag ntsev + kev caij tsheb kauj vab khov-thaw nrog<0.03% kev puas tsuaj/xyoo.
5. Kev Tshuaj Xyuas Tus Nqi: Tus Nqi Mus Ntev Dua Tus Nqi Pib
Kev faib tawm rau qhov project lag luam 10,000 sq.ft:
| Tus Nqi Tseem Ceeb | Pob Zeb Ib Txwm | 0 Pob Zeb Silica |
| Khoom siv | $42,000 | $48,000 |
| Kev Tswj Cov Pluag Av | $9,200 | $0 |
| Cov Khoom Siv Tiv Thaiv Tus Kheej Rau Cov Neeg Ua Haujlwm | $3,800 | $800 (cov ntaub npog qhov ncauj yooj yim) |
| Kev Pov Hwm | $12,000 | $7,000(qib kev phom sij qis dua) |
| Kev Txij Nkawm 10 Xyoo | $28,500 | $6,000 |
| TAG NRHO | $95,500 | $61,800 |
"ROI tsis yog tsuas yog nyiaj txiag xwb - nws yog kev ncaj ncees. Tsis muaj tus neeg ua haujlwm yuav tsum pauv kev noj qab haus huv rau cov nyiaj hli."
– Elena Rodriguez, Lub Koom Haum Tsim Kho Kom Ruaj Khov
6. Siv Zero Silica: Daim Ntawv Teev Npe ntawm Tus Neeg Cog Lus
Rau kev txais yuav tsis muaj teeb meem:
1. Kev Sib Txuas Lus ntawm Cov Cuab Yeej
•Ua haujlwm nrog cov hniav pob zeb diamond txheem (tsis muaj cov cuab yeej tshwj xeeb)
• Tsis txhob siv cov khoom tungsten-carbide (tej zaum yuav ua rau lub matrix kub dhau)
2. Cov txheej txheem nplaum
•Siv cov mortars uas ua los ntawm epoxy (zoo rau geopolymer)
• Lub Tswv Yim Zoo: Ntxiv 5% silica fume rau qhov chaw kho sai
3. Kev Saib Xyuas
• Ntxuav nrog cov tshuaj ntxuav pH-neutral - cov kua qaub ua rau cov geopolymer bonds puas tsuaj ntau xyoo dhau los
7. Yav Tom Ntej: Dhau Kev Ua Raws Cai
Cov kev cai lij choj zoo li OSHA txoj cai lij choj silica xyoo 2016 (txwv tsis pub raug rau50 μg/m³) thawb kom siv. Tab sis cov tuam txhab uas xav txog yav tom ntej siv0 Pob Zeb Silicarau:
•Daim Ntawv Pov Thawj LEEDTau Txais Cov Qhab Nia Zoo ntawm Huab Cua Hauv Tsev + Kev Tsim Kho Tshiab
•Kev Ua Raws Cai ntawm B Corp: Sib phim nrog cov ntsuas kev noj qab haus huv ntawm cov neeg ua haujlwm
•Kev Lag Luam Zoo74% ntawm cov neeg siv khoom lag luam them tus nqi ntxiv rau cov ntaub ntawv "tsis muaj kev phom sij" (Dodge Data Report)
8. Koj Kauj Ruam Tom Ntej
"Qhov no tsis yog lwm yam khoom xwb - nws yog lub hauv paus tseem ceeb rau kev lag luam," Dr. Aris Thorne, tus kws tshawb fawb txog cov ntaub ntawv ntawm MIT hais. Sim nws lub peev xwm:
Thov Ib Lub Khoom Siv Qauv: Kev sim tshuaj tiv thaiv stain
Nkag mus rau Kev Xam Xaj ROI Tshwj Xeeb: Sau koj cov variables project
Saib Qhov Kev Qhia Txog Hauv Tsev: Saib kev txiav yam tsis muaj lub tshuab nqus tsev
Lub Tswv Yim KawgCov qauv zoo tshaj plaws tsis yog tsuas yog tsim los kom kav ntev xwb - lawv tau tsim los nrog kev hwm rau txhua txhais tes uas ua rau lawv zoo nkauj.
