Xaiv Blasting Abrasive Media

Ob qho tib si yooj yim thiab cov cuab yeej siv siab heev tsim tau siv rau hauv cov tshuab abrasive blasting. Txawm li cas los xij, ob lub kaw lus tsis tuaj yeem ua haujlwm yam tsis muaj xov xwm abrasive. Cov khoom no yog lub plawv ntawm cov txheej txheem blasting, thiab nws muaj nyob rau hauv ntau hom kev npaj rau ntau yam kev siv.

Nrog cua tshuab tshuab, cov xov xwm nkag mus rau hauv cov cua compressed los ntawm lub lauj kaub los yog thawv. Valves funnel cov khoom lag luam tawm mus rau hauv lub tshuab tawg, thiab cov txheej txheem rov ua dua tso cai rau cov xov xwm rov qab los. Centrifugal txhaj tshuaj blasting tshuab kuj muaj lub thawv tuav. Cov txheej txheem no siv cov khoom noj khoom haus xa tawm mus rau hauv lub log tig thiab mus rau qhov chaw kho mob ua ntej yuav sau thiab rov ua dua.

Cov khoom siv abrasive tuaj yeem yog ntxhia, organic, ceramic, yas, lossis hlau. Txhua lub hauv paus tshuaj ua haujlwm tshwj xeeb abrasive thiab muaj cov khoom tseem ceeb abrasive.

Muaj plaub yam khoom uas yuav tsum tau xav txog hauv kev ua haujlwm abrasive blasting:

1.     Cov duab:Media particle zoo yog qhov tseem ceeb rau qhov kawg ntawm qhov kawg. Round-shaped hais yog tsawg abrasive tshaj angular duab.

2.     Loj:Media particle loj yog ntsuas hauv "mesh." Qhov no yog kev tshuaj ntsuam xyuas los ntawm qhov ib square inch qhov twg cov xov xwm loj loj lim los ntawm ntau qhov hauv ib lub npov mesh piv rau cov khoom loj.

3.     Hardness:Cov khoom tawv tawv zoo li cov hlau txhaj tshuaj nkag mus tob rau hauv cov ntaub ntawv tshaj li cov xov xwm mos xws li cov khoom yas. Nws yog ib qho tseem ceeb uas blasting media hardness tau sib haum nrog rau saum npoo kom tsis txhob muaj kev puas tsuaj irreversible.

4.     Ceev:Ntiv cov xov xwm me me muaj ntau qhov loj ib qho loj dua li cov khoom siv sib luag. Zoo li hardness, txoj cai xov xwm ceev yog qhov tseem ceeb los ua txoj haujlwm zoo yam tsis muaj kev cuam tshuam rau qhov chaw kho mob.

Txhua qhov sib txawv ntawm cov khoom siv xov xwm abrasive muaj nws tus kheej zoo tshaj qhov zoo li, qhov loj me, hardness, thiab ntom. Kev xaiv cov khoom siv xov xwm feem ntau yog nyob ntawm qhov chaw uas tau npaj lossis kho, tsis tas yuav siv cov khoom siv abrasive. Nov yog cov ntaub ntawv xov xwm abrasive uas koj yuav pom hauv kev ua haujlwm abrasive blasting:

·         Hlau phom thiab steel grit:Hlau txhaj tshuaj yog puag ncig thaum steel grit muaj cov duab angular. Nws yog ib qho zoo heev abrasive rau nws roughness thiab siab recyclability. Rau cov hauj lwm hnyav, tsis muaj dab tsi ntaus steel abrasives.

·         Aluminium oxide:Aluminium oxide nta nws cov hardness siab thiab lub zog. Rau cov tawv tawv uas yuav tsum tau polishing zoo, aluminium oxide yog cov xov xwm zoo meej. Nws yog ib qho nyuaj, rov siv tau, thiab tus nqi qis.

·         Silicon carbide:Nws yog cov khoom siv tawv tawv tshaj plaws muaj. Cov xov xwm no los ntawm qhov ntau thiab tsawg los ntawm cov hmoov zoo mus rau coarse grit. Nws yog haum zoo hauv kev tu qhov nyuaj tshaj plaws.

·         iav hlaws:Nws yog round soda-lime iav. Piv nrog rau lwm cov ntaub ntawv, iav tsis yog hnyav li blasting xov xwm xws li hlau txhaj tshuaj los yog silicon carbide. Abrasives ntawm iav hlaws muaj kev ntxhov siab me ntsis ntawm qhov chaw los ua kom pom kev kaj thiab satin matte hom tiav.

·         Kev zoo nkauj Dub:Qhov no yog cov khoom siv coal slag. Dub Beauty yog ntxhib heev thiab haum rau hnyav xeb thiab xim tshem tawm.

·         Cov yas:Abrasives ua los ntawm cov yas sib txawv ntawm qhov loj, zoo, hardness, thiab ntom. Cov khoom siv yas muaj xws li polystyrene thiab polycarbonate. Nws yog mos abrasive zoo tagnrho rau kev kho fiberglass, pwm, los yog yas qhov chaw tu.

·         Walnut plhaub:Black walnut shells yog cov zoo heev abrasives rau cov hlau mos thiab yas nto. Walnut plhaub yog pheej yig thiab yooj yim muaj thiab ua compostable.

·         Pob kws cobs:Zoo li walnut shells, pob kws cobs yog mos organic abrasives. Lawv tau siv rau ntawm qhov chaw mos kom tshem tawm cov kab mob xws li roj, roj, thiab grime es tsis yog xeb thiab xim.
