He aha te mea puehu auaha?

rauemi auaha āhuatanga e te kaha o whai hua mahi aunoa. Ki te to ratou paru awhina tango, atawhai patua hua papa ma ki waikura, me te peita. Te mahi huānga, i roto i te meka, he reira granules auaha, e taea whai āhua rerekē me te rahi. Ko tētahi momo o taua granules he puehu auaha, e taea e takenga wheketere kia te hua o hangaruatanga ururua me te t ranei. D.

ngā mōhiohio whānui e pā ana te puehu auaha

kia whai puehu āhuatanga rerekē, me te take, engari i roto i te nuinga o te wā ko te hua houhou o te tukatuka hua whakarewa me te rakau tenei. Tikanga, te paura auaha tukua te i roto i te tukanga o te raveraa i te huri, me te oro ngā mahi. Ka taea te hanga puehu me te tukatuka o papa whare, a i roto i ngā pukapuka nui i roto i te whakatinanatanga o ngā mahi i roto i te tauine ahumahi. I roto i te wā e rua i hanga maitai te puehu auaha rite ki te hua o te whakangaromanga o te rauemi maimoatanga matua. Te nuinga o enei ururua waiho nga wira huri i te mahi mīhini i runga i te mata ūnga ki te kia tukinotia. A, no te kore te mea tonu tenei puehu whakarewa - te tikanga ngā tito e hoki ngā matūriki auaha o te kamaka.

hanganga rauemi

abrasives tukatuka nuinga e whai wāhi ki ngā hua o te maitai ferrous. i taea e te reira i te wahi e heke mai mō te taputapu mīhini, AUTOMOBILES me wāhanga, me te rauemi hanga. Ko te pūtake o tetahi hanganga hanga he rino puehu - o te tikanga o te 30%. Ko te rōrahi tuarua ko te nuinga o te ihirangi o te konumohe ōkai - alumina, ahakoa e taea hoki rerekē tona kounga. Ko te huānga Pākēha tuarua puehu auaha ngā ūkuikui, te ateneke, nika, konupora, chromium me te rite. D. Tei nui i runga pehea te mata mahi mahi e te puehu auaha. Composition ranunga tohaina maha ngā āhuatanga o te tauine, te waikura, me coatings peita tawhito. Mau, ki te aro taua accretions technique maha whakamahia tango auaha.

Ngā momo o te puehu auaha

hāngai Whakarōpū i runga i te maha o te mau parau tumu o te wehenga o te matūriki auaha. I roto i te mau rave'a e rave rahi e ti'aturi i runga i te tukatuka rauemi tono ratou. Hei tauira, ki te te taputapu huri ki te pupuha i te puka o te porowhita, ka taea te huaina te puehu hua silicon. mahi ano e te whakamahi o sandblasting mihini, i i whakamahia tuatahitia mongamonga purapura auaha. Ka taea e ratou rerekē i roto i te rahi me te āhua, engari tonu te raruraru te taua - te tango o coatings mata faufaa ranei te whakarite i te whakapati o te workpiece. Ko te tukatuka whakamutunga o te hua i roto i tenei take e waiho te whakarewa puehu auaha, engari i roto i te puka fakakehei. He mea nui ki te mōhio e, pērā pūhui silicon, taea te whakamahi taua puehu i roto i ngā mahi o muri, a ka kua whakamahia rite te paura whakarewa mo huri.

āhuatanga o

Ko te tawhā me ngā āhuatanga o te puehu i hanga takoto e nga tikanga o ngā mahi, me te rauemi e whakamahia ana. Hei tauira, i roto i te mīhini-hanga hua hinonga mīhini e rapua e mutunga nui-pū o ngā mata ki te hōputu āhuahanga e hiahiatia ana. I roto i tenei tukatuka i waenganui i nga rārangi me te hua hurihia i hanga te krupnofraktsionnaya puehu nei āhuatanga e taea rerekē i 5 ki te 10 microns. Ko te tikanga e taea e te i te whakaetonga o te tauine rawa o te tikanga o te 20% i roto i te taimaha. Ko te toharite o taua paheke hinonga puehu ko e pā ana ki 200 g ia 1 ton o awhiowhio whakarewa tukinotia. Ki te te ato'a whakamahia me scarfing, taea tino whakanui i te rōrahi o te ururua auaha. A, no te raveraa i ngā mahi mira i roto i ngā pukapuka o iti puehu auaha i hanga e te pūāhua hautanga iti. He matūriki puehu pērā i roto i ona microns diameter 0.5-1.5. Otiia e kore e whakaaro e te wehenga o te matūriki pai he haumaru atu mea nui. Tuatahi, he hautanga nui o te tangohanga puehu whakahaere mahi. Tuarua, mai i te wāhi hauora o te tirohanga, he mōrearea ki te pūnaha romahā te puehu pai. Na ko reira e tika ana ki te tātari i roto i te taipitopito te pātai o te aha he mea e tika ana ki te mahi ki te tohanga noa o te ururua auaha i roto i te tukatuka.

He mōrearea te puehu auaha?

Te kore te puehu tango whakatupuranga pūnaha pai o te puehu whakarewa te taniwha, ka arahi ki te whakahörapatanga o te rangi o te wāhi mahi. I roto i taua tikanga maha whakawhanake mahi mate fitters. kia ngā taua ma'i pneumoconiosis, puehu Bronchitis, huangō, a na i runga i. ai D. kia te whanaketanga o te mate te putanga o te ritenga pūkahukahu auau me matūriki auaha i te tukatuka taputapu, workpieces me ngā āhuatanga o te hanganga. Na reira, ko te mea nui ki te tīmatanga whakarite i te pūnaha e ka whakarite tango tōtika o te puehu auaha tika i roto i te taiao mahi. Tei runga i te rahi me te e whakaritea tikanga whakahaere o enei pūnaha rite ki te mau parau tumu rerekē. kia waiho te paerewa tenei kaihoroi ahumahi mārua, hono ki te mīhini huri, me te ventilation ahumahi.

tikanga tango

āhuatanga auaha iti tukatuka mā te whakamahi i huri mihini rauemi te nuinga kohia te ka tukua i roto i ngā tāngata whai motuhake. E mea nui ki te whakaaro e pā ana ki ngā huarahi ki te ke fakafou te kaupapa o te puehu. I roto i te nuinga o te wā, faatiti'aifarohia te raruraru e rererangi, wettable i te wai. pupuhi Water arai te puehu ki te raupo, rite rawa ki te tātari. Next ano i hake wai ma atu nga wahi o te whakatau puehu. Hoki te kakama nui e taea whakarato i tētahi pūnaha ventilation hongere awakeri e ka ārai me te haapurararaa matapōkere o matūriki iti. I roto i te hanga o piki te whakamahi i te kaihoroi mārua kua whakahuatia ki te puehu auaha, e i te wa o te tohatoha o matūriki ngotea mai ratou i roto i te ipu motuhake, te ārai titaritari ana. More pai pūnaha ki te aro abrasion koraha whai wāhi hoki te whakamahi o te rere o te hau. Hei tauira, i roto i te rerenga waihanga kia whakahaeretia ejector, tāuta nei i roto i te pokapū o te tinana whakawehe.

mutunga

Waihanga o matūriki auaha ko te āhuatanga momotu, e kore anake i roto i te tukanga o te huri, me te oro. Ahakoa he angamaheni "mīhini" tapahi o te whakarewa whai wāhi ki te hanganga o taua āhuatanga. Ehara i te mea i nga wa katoa e taea ana ki te whakarato i te pūnaha i roto i nei kia nekehia atu aunoa i te puehu auaha. Tautautefito i roto i te taiao kāinga, ka hoko i te ngā mahi hanga tetahi-wā rawa hoki tenei te mārua taua koretake. I roto i te wā, pērā i te mea e tika ana ki te tuatahi o te katoa whakaaro tiaki romahā whaiaro. Ki te whakaaro ki te tiaki o te papa ruma, ka waiho i te reira e kore i roto i te wahi i mua i te mahi ki te taupoki ana ratou ki te konumohe. A ko reira obligatory ki te whakarite ventilation - i te iti rawa i roto i te matapihi ki te huarahi.
