1. Te Tūponotanga Wahangu i tō Papa Mahi
"I maremare ahau mō ngā wiki i muri i te tapahi i ngā papa kaunta karāhe," te mahara o Miguel Hernandez, he kaimahi kōhatu me te 22 tau o te wheako. "I whakakitea mai e taku tākuta he hihi-X - he koha iti kei runga i ōku pukahukahu katoa."
Ehara i te mea onge te kōrero mō Miguel.Puehu silica tioata– ka tukuna i te wā e tapahi ana, e huri ana, e keri ana rānei i te kōhatu tuku iho – kua whakarōpūtia e te WHO heiPūmua mate pukupuku rōpū 1He mea whakapouri ngā tatauranga:
•2.3 miriona+ Ngā kaimahi o Amerika e pāngia ana i ia tau (OSHA)
•600+ ngā kēhi silicosis houtātaritanga ā-tau (CDC)
•Wā whakaroaKa puta ngā tohu i muri i te 10-30 tau o te pānga
Te paradoxHe mea nui te kohatu tūturu mō tōna pakari, engari ko tōna tukatuka ka mōrearea ki te hunga e hanga ana i ō tātou wāhi.
2. Te Pakaritanga: Te Pūtaiao kei Muri i te 0 Kohatu Hiraka
He rerekē ki ngā momo "iti-hirika" (he maha ngā wā kei roto ko te 5-30% te hihika), he pono0 Kōhatu Hirakae whakamahi ana i te hangarau geopolymer:
Te Hanganga
| Hipanga | Kohatu Tuku Iho | 0 Kōhatu Hiraka |
| Te kimi rauemi | Karati/kuata i kerihia | Ngā putunga kohuke kore-silica kua tohua (hei tauira, nepheline syenite) |
| Te here | Ngā hononga tioata taiao | Sima geopolymer + nano-whakapakari |
| Tūponotanga | Ka tukuna te silica i te wā e tapahia ana | Kore rawa he silica e taea te manawa |
Auahatanga Matua: Ka whakakapia te tūranga hanganga o te silica e ngā muka alumina nano-rahi, ā, ka tutuki i ēnei:
•Kaha Pehi: 18,500 psi (ki te whakataurite ki te 15,000 psi o te karāhe)
•Te Pūmautanga o te WeraĀtete ki te pakaru i te -30°C ki te 150°C
•Te mimiti wai: <0.1% (pai rawa atu mō ngā wāhi mākū)
3. Te Wāhi e Hiranga ake ai te Kohatu Hiraka Kore – Ngā Kaupapa Tuturu
Take A: Te Whakahoutanga o te Hōhipera Tamariki (Seattle)
"Kāore i taea e mātou te tūpono ki te puehu i te taha o te pūnaha whakapūmau hau i te ICU. E 0 ngā pereti silica i tapahia i te papaanga mā te whakamahi i ngā kani mākū noa – kāore i hiahiatia he tēneti aukati."
– Kaiārahi Kaupapa, Liora Chen
Ngā Hua:
•22% te tere ake o te tāutangavs. te kōhatu tuku iho
•$14,500 kua penapenahiamō ngā utu tātari hau
Take B: Papa o te Taunga Rererangi e Tino Waka ana (Whānuitanga o te Taunga Rererangi o Tōkyō)
I muri i ngā marama 18 o te nui o ngā tueke:
| Rauemi | Te Whakamaunga o te Mata (mm) | Ātete ki te paru |
| Karāniti | 0.8 | He tae hinu ngawari |
| 0 Kōhatu Hiraka | 0.2 | Kore rawa e uru (ngā pore kua hiritia) |
4. Te Whakakore i ngā Pūrākau e 3
Pūrākau 1"Ko te tikanga o te kore-silica he ngoikore."
Te pono: Ka hangaia e te nano-whakapakaringā matihiko tioata e hono ana(kua whakamātauria i roto i te taiwhanga mō te tutuki i ngā whakaritenga mō te rohe rū whenua 4).
Pūrākau 2"He āhua hangai te āhua."
Te ao tūturu: E whai ana i te whakaputanga o ngā uaua māori mātauira waikura kohuke– he maha ngā kaihoahoa e whakaaro pohehe ana he māpere kounga teitei tēnei.
Pūrākau 3"Mō ngā whakapaipai o roto anake."
Taunakitanga: Whakamahia ki te Ara Papa o te Whanga o Boston – e tu atu ana i te rehu tote + te huringa huka-rewa me<0.03% te hekenga/tau.
5. Tātari Utu: Uara Wā Roa ki te Utu Tīmatanga
Wehenga mō tētahi kaupapa arumoni 10,000 putu tapawha te rahi:
| Tauwehenga Utu | Kohatu Tuku Iho | 0 Kōhatu Hiraka |
| Rauemi | $42,000 | $48,000 |
| Whakahaere Puehu | $9,200 | $0 |
| Ngā taputapu tiaki tinana mō ngā kaimahi | $3,800 | $800 (ngā kopare taketake) |
| Inihua | $12,000 | $7,000(whakatauranga mōrearea iti iho) |
| Te Tiaki 10-Tau | $28,500 | $6,000 |
| KATOA | $95,500 | $61,800 |
"Ehara i te mea ko te pūtea anake te take o te ROI – engari he tikanga matatika. Kaua tetahi kaimahi e whakawhiti i te hauora mō te utu."
– Elena Rodriguez, Te Rōpū Kaihanga Tauwhiro
6. Te Whakatinana i te Kore Silica: He Rārangi Arowhai a te Kaimahi
Mō te whakatinanatanga maeneene:
1. Hototahitanga o ngā Utauta
•Ka mahi tahi me ngā mata taimana paerewa (kāore he taputapu motuhake)
•Āraihia ngā wahi tungsten-carbide (tērā pea ka wera rawa te anga)
2. Tikanga Piripiri
•Whakamahia he moata epoxy (he pai mō te geopolymer)
•Tohutohu Tohunga: Tāpirihia he 5% kohu silica mō ngā tautuhinga tere-whakaora
3. Te Tiaki
•Horoia ki ngā kaihoroi pH-kore – ka pakaru ngā hononga geopolymer i roto i ngā tekau tau ka pakaru ngā otinga waikawa
7. Te Anamata: Kei tua atu i te Whakatutukitanga
Ngā ture pēnei i te ture silica a OSHA i te tau 2016 (e whakawhāiti ana i te pānga ki50 µg/m³) i akiaki i te whakatinanatanga. Engari e whakamahi ana ngā umanga whakaaro whakamua0 Kōhatu Hirakamō:
•Tiwhikete LEED: Whiwhi whiwhinga Kounga Hau o Roto + Auahatanga
•Te Whakatutukitanga o te B Corp: E hangai ana ki ngā inenga oranga o ngā kaimahi
•Te taha hokohoko: 74% o ngā kiritaki arumoni e utu ana i te piremi mō ngā rauemi "kua manatokohia kāore he tūponotanga" (Pūrongo Raraunga Dodge)
8. Tō Hipanga e Whai Ake Nei
"Ehara tēnei i te mea he hua noa iho – he pūwāhi matua tēnei mō te umanga," te kī a Tākuta Aris Thorne, he kaipūtaiao rauemi i MIT. Whakamātauria tōna pūmanawa:
Tonoa he Kete TauiraWhakamātauria te ātete ki te paru
Tātaitai ROI Ritenga UrungaWhakauruhia ō taurangi kaupapa
Mātakihia te Whakaaturanga i te PaeTirohia te tapahi me te kore he pūnaha korehau
Whakaaro WhakamutungaKāore ngā hanganga pai rawa i hangaia kia roa noa – engari he mea hanga me te whakaute ki ia ringa e hanga ana i a rātou.
