Kodi Kuphulika Kopanda Dustless Kulibe Fumbi?

Monga njira yatsopano komanso yowongoleredwa yophulitsa abrasive, kuphulika kopanda fumbi kumapindulitsa kwambiri. Zimatengedwa kuti ndizofala kwambiri pokonzekera pamwamba pa njira yoyeretsera komanso yosamalira chilengedwe.

Pali zabwino zambiri za kuphulika kopanda fumbi, chimodzi mwazinthu zazikulu zomwe zimaganiziridwa ndikuti sikutulutsa fumbi. Komabe, tapa palibe chinthu chonga "chopanda fumbi" kapena "chopanda fumbi" kuphulika pamakampani okonzekera pamwamba. Zida zonse zophulitsa abrasive zomwe zimagwira ntchito bwino zimatulutsa fumbi.

Ndiye, mwina mukuganiza kuti chifukwa chiyani kumatchedwa kuphulika kopanda fumbi ngati si fumbi la ziro?

Kodi fumbi limachitika bwanji?

Kadulidwe ka abrasive media ikasweka, imasweka kukhala tinthu tating'ono. Zing'onozing'ono zazing'ono particles amalephera kugwa pansi chifukwa chosowa misa pamaso pa mpweya chipwirikiti opangidwa pa abrasive kuphulika.

Ndi kuphulika konyowa, abrasive imakutidwapamadzi. Tinthu tating'onoting'ono tikamaphwanyidwa, timadontho tating'ono tating'ono tomwe timakhalaatsekeredwandi madzi ndi mphamvu yokoka zimawakokera pansi, ngakhale mpweya chipwirikiti.

Komabe, tinthu tating'onoting'ono tating'onoting'ono, kotero kuti ngakhale titakulungidwa m'madzi, sizitenga misa yokwanira kuthana ndi mphamvu ya chipwirikiti cha mpweya, ndipo ikukhala.zandegemumlengalenga. Kuphatikiza apo, sizinthu zonse zazing'ono zomwe zimakutidwa m'madzi. Tinthu tating'onoting'ono timene timatulutsa kuchokera mkati mowuma wa tinthu tambirimbiri sitingakhale wothira nkomwe. Ichi ndichifukwa chake palibe kuphulika konyowa komwe kungathe kuthetsa fumbi.

Kodi tiyenera kuyang'ana chiyani?

Kuphulika konyowa kumagwiritsa ntchito madzi kuti agwire tinthu tating'onoting'ono tisanalowe mumlengalenga, koma sizingagwire zonse. Komabe, zomwe zimajambula zimapangitsa kuti njirayi ikhale imodzi yomwe ma blasters ambiri amakonda kuposa njira zachikhalidwe.

Mabotolo ophulitsa amagwiritsa ntchito zoteteza kupuma kuti asatuluke fumbi, zitsulo zolemera, ndi zinthu zina zovulaza m'mapapu awo. Chodetsa nkhawa kwambiri ndi fumbi la silica, lomwe limayambitsa silicosis.Silicosis imayamba chifukwa cha kupuma mu tinthu tating'ono tosaoneka (silica) topangidwa ndi sandblasting. Silika ndi gawo lamchenga, miyala, ndi miyala ina yamchere. Tizilombozi timawononga mapapu anu pakapita nthawi zomwe zingakulepheretseni kupuma.

Wophulika yemwe amagwira ntchito molakwika kuti njira yake sikupanga fumbi angaganize momveka kuti chitetezo cha kupuma sikofunikira.

Kumvetsetsa kuti kuphulika konyowa kumapangabe tinthu toyipa izi ndikofunikira pa thanzi lanu.

Ubwino wa kuphulitsa konyowa ndi chiyani?

Ngati kutetezedwa koyenera kuchitidwa, phindu la kuphulika konyowa kwamadzi kumakhala kochuluka. Choyamba, chitetezo chanu chimakhala chomasuka komanso chopepuka. Chovala chamoto chomwe chiyenera kuvala kuti chiphulike chonyowa chimaphatikizapo kuteteza maso, chitetezo chakumva, ndi chopumira.

Kumbali ina, suti zowuma zowuma zimaphatikizapo suti yophulika, magolovesi, chisoti / hood, ndi chitetezo cha makutu.

Phindu linanso ndilakuti kusungirako zida zophulitsa zonyowa ndizocheperako poyerekeza ndi kuphulika kwachikhalidwe. M'malo mowonetsetsa kuti malo omwe akuphulika ali ndi zonse, phula losavuta lokhazikitsidwa kuti liyeretsedwe mosavuta ndizomwe mungafune.

Kuphulika kotereku kumagwiritsanso ntchito zoulutsira mawu zocheperako poyerekeza ndi kuphulika kowuma komanso kutsika kwamadzi kuyerekeza ndi kuphulika kwa slurry, kukupulumutsani ndalama pakapita nthawi.

Ndi kuphulika konyowa kwa abrasive, madziwa amathandizanso kuti zitsulo zazitsulo zikhale zozizira pamene akuphulika. Izi ndizofunikira makamaka pakuphulitsa zitsulo zocheperako.

Kodi tiyenera kuyang'ana pa kuphulika konyowa kwa abrasive?

Kuphulika konyowa kungagwiritsidwe ntchito m'njira zosiyanasiyana: kuyambira kukonzanso zakale mpaka kukonzanso pamwamba. Zimapangitsanso kuchepa kwa ndalama zogwirira ntchito komanso kuvala kwa zida poyerekeza ndi mitundu ina ya kuphulika.

Ngakhale sichingathetseretu fumbi, ikadali chisankho chabwino ngati mukufuna malo abwino ophulika ophulika ndipo mumakonda njira yoyesedwa nthawi.
