Qhuav Ice Cleaning Tshuab Keeb Kwm Kev Txhim Kho

Xyoo 1930, Tebchaws Meskas tau tsim "cov dej khov qhuav" rau kev sim kuaj.
Xyoo 1945, US Navy tau siv cov dej khov qhuav los ua qhov nruab nrab kom tshem tawm cov roj ntau.
Xyoo 1963, Reginald Lind tau txais daim ntawv pov thawj rau "tshem cov nqaij ntawm cov pob txha" los ntawm kev txau cov pa roj carbon dioxide.
Xyoo 1972, Edwin Reese tau txais daim ntawv pov thawj rau "txhaj cov dej khov qhuav qhuav kom tshem tawm cov khoom seem ntawm cov khoom."
Xyoo 1977, Calvin Fung tau txais patent rau "sandblasting nrog volatile particle media."
Thaum xyoo 1980s, Tebchaws Meskas tau siv cov ntsiab lus ntawm cov dej khov qhuav qhuav txau cov kab mob sib kis thiab qhov kub thiab txias qis los daws cov kev tu thiab tu ntawm satellite navigation systems thiab cov khoom siv hluav taws xob nuclear hauv kev ua tub rog thiab cov kev xav tau tshwj xeeb. Thaum lub sij hawm ntawd, lub tshuab dej khov muaj qhov ntxhib, qhov loj me, thiab hnyav txog 60 tons. Tsis tas li ntawd, kev tsim khoom ntawm cov dej khov qhuav qhuav yog qhov tsawg heev, lub hardness tsis siab, thiab cov lus qhia tshwj xeeb thiab qhov ntau thiab tsawg yog ib leeg, uas txwv tsis pub siv ntau.
Nyob rau xyoo 1980s, vim muaj kev txhim kho txuas ntxiv ntawm kev ua tiav thiab kev siv tshuab hluav taws xob sib xyaw ua ke, Tebchaws Asmeskas tau txhim kho loj rau cov tshuab ua dej khov qhuav thiab cov tshuab tshuaj tsuag, txo lawv qhov loj thiab qhov hnyav mus txog 2 tons. Tsis tas li ntawd, kev siv cov tshuab micro-cim sib sib zog nqus cua txias tau nce qhov kev siv CO2 los ntawm ze li ntawm 2 npaug, thiab ua rau cov dej khov qhuav qhuav ntawm qhov sib txawv hardness thiab loj, txo cov nqi, ua rau cov cuab yeej hloov pauv ntawm kev ua tub rog mus rau pej xeem thiab kev lag luam, thiab txhim kho. ceev ceev.
Nyob rau xyoo 1990, qee cov phau ntawv tshaj lij thiab cov ntawv xov xwm ntawm kev tu thiab casting hauv Suav teb tsuas yog luv luv qhia txog cov tshuab no. Thaum xyoo 1990, Tuam Tshoj tau qhia cov khoom siv dej khov qhuav qhuav thaum qhia txog cov khoom siv los ntawm txawv teb chaws. Shanghai Automobile Nonferrous Foundry, uas tau siv cov dej khov qhuav qhuav ua ntej, tau txais txiaj ntsig zoo los ntawm kev ntxuav cov dej khov qhuav, ua kom muaj txiaj ntsig zoo ntawm castings thiab txhim kho kev tsim khoom.
Lub ntiaj teb kev tsim khoom lag luam tau maj mam hloov mus rau Tuam Tshoj. kuv lub teb chaws "Txoj Cai Lij Choj Tshaj Lij Tshaj Lij Tshaj Lij Tshaj Lij" thiab lwm txoj cai tau tshaj tawm, txhawb nqa kev tsim khoom huv si, tsom mus rau kev tsim cov txheej txheem, khoom siv thiab thev naus laus zis nrog kev siv cov peev txheej siab thiab tsis tshua muaj kuab paug tsim los hloov cov txheej txheem rov qab, khoom siv thiab thev naus laus zis nrog cov khoom siv siab. , kev siv hluav taws xob thiab kev tsim muaj kuab paug. Txoj cai lij choj ntawm ib puag ncig kev ua qias tuaj kuj tseem yuav tswj hwm nruj dua rau kev lag luam emissions, xav kom cov tuam txhab ua "kev tsim khoom huv si". "Cov Txheej Txheem ntawm Tuam Tshoj Txoj Cai Tswj Kev Txuag Dej" tau tshaj tawm los ntawm National Development thiab Reform Commission thaum lub Tsib Hlis 2005 tau taw qhia meej tias "tsim cov cuab yeej tu tshuab. Txhawb nqa cov dej khov qhuav qhuav, tshuaj ntxuav, tsis nres hauv online tu thiab lwm yam thev naus laus zis". Cov no tau muab lub sijhawm zoo rau daim ntawv thov thiab kev txhawb nqa cov tshuab ntxuav dej khov qhuav hauv kuv lub tebchaws, thiab cov tshuab ntxuav dej khov qhuav yuav siv dav thiab tsim dua.
