Koj puas paub txog CLEANROOM?

Yug ntawm chav huv

Kev tshwm sim thiab kev loj hlob ntawm tag nrho cov thev naus laus zis yog vim kev xav tau ntau lawm. Cleanroom technology yog tsis muaj kev zam. Thaum Ntiaj Teb Tsov Rog II, Tebchaws Meskas tau tsim cov huab cua-floating gyroscopes rau aircraft navigation. Vim qhov tsis ruaj tsis khov, txhua 10 gyroscopes yuav tsum tau rov ua dua qhov nruab nrab ntawm 120 zaug. Thaum Tsov Rog Kaus Lim Kauslim thaum xyoo 1950, Tebchaws Meskas tau hloov ntau dua ib lab cov khoom siv hluav taws xob hauv 160,000 cov khoom siv hluav taws xob sib txuas lus. Radars ua tsis tau 84% ntawm lub sijhawm thiab submarine sonars ua tsis tau 48% ntawm lub sijhawm. Yog vim li cas yog qhov kev ntseeg ntawm cov khoom siv hluav taws xob thiab cov khoom siv tsis zoo thiab qhov tsis zoo. Cov tub rog thiab cov neeg tsim khoom tau tshawb xyuas cov laj thawj thiab thaum kawg txiav txim siab los ntawm ntau yam uas nws muaj feem xyuam rau qhov chaw tsim khoom tsis huv. Txawm hais tias ntau yam kev ntsuas nruj tau raug coj los kaw lub rooj cob qhia ntau lawm thaum lub sijhawm ntawd, qhov cuam tshuam tsawg heev. Yog li qhov no yog qhov yug ntawm chav huv!

Kev tsim kho chav huv

Thawj theem

Nws tsis yog txog thaum xyoo 1950s uas HEPA (High Efficiency Particulate Air Filter) tau tsim los ntawm US Atomic Energy Commission hauv xyoo 1951 los daws cov teeb meem ntawm kev ntes cov plua plav hluav taws xob uas tsim kev puas tsuaj rau tib neeg lub cev tau siv rau huab cua pom ntawm lub ntau lawm rhiav, thiab niaj hnub cleanroom tau yug tiag tiag.

Qhov thib ob theem

Nyob rau xyoo 1961, Willis Whitfield, tus kws tshawb fawb laus ntawm Sandia National Laboratories hauv Tebchaws Meskas, tau tshaj tawm cov txheej txheem ua haujlwm ntawm huab cua huv, uas yog hu ua laminar flow, tam sim no hu ua unidirectional flow, thiab siv nws rau qhov tseeb engineering. Txij thaum ntawd los, cov chav huv huv tau mus txog qhov tsis tau muaj dua qhov kev huv huv dua.

Qhov thib peb theem

Nyob rau hauv tib lub xyoo, US Air Force tsim thiab muab lub ntiaj teb no tus thawj chav huv chav standard TO-00-25--203 Air Force Directive "Tsim thiab ua hauj lwm yam ntxwv Standards rau Cleanroom thiab huv si.BLub hauv paus no, Tsoom Fwv Teb Chaws Standard FED-STD-209, uas faib chav huv huv rau hauv peb theem, tau tshaj tawm thaum Lub Kaum Ob Hlis 1963. Txog tam sim no, tus qauv ntawm kev ua tiav chav huv huv tau tsim.

Peb qhov kev nce qib tseem ceeb saum toj no feem ntau tau qhuas tias yog peb qhov tseem ceeb hauv keeb kwm ntawm kev tsim kho chav huv niaj hnub.

Nyob rau hauv nruab nrab-1960s, chav huv huv tau tshwm sim hauv ntau qhov chaw lag luam hauv Tebchaws Meskas. Nws tsis yog tsuas yog siv rau hauv kev lag luam tub rog, tab sis kuj txhawb nqa hauv electronics, optics, micro bearings, micro motors, photosensitive films, ultrapure chemical reagents thiab lwm yam kev lag luam sectors, uas tau ua lub luag haujlwm tseem ceeb hauv kev txhawb txoj kev loj hlob ntawm science thiab technology thiab kev lag luam. lub sijhawm ntawd. Vim li no, cov hauv qab no yog cov lus qhia ntxaws ntxaws hauv tsev thiab txawv teb chaws.

Kev sib piv kev loj hlob

Txawv teb chaws

Thaum ntxov xyoo 1950, US Atomic Energy Commission tau qhia txog qhov ua tau zoo ntawm cov huab cua lim (HEPA) hauv xyoo 1950 los daws cov teeb meem ntawm kev ntes cov plua plav hluav taws xob uas tsim kev puas tsuaj rau tib neeg lub cev, dhau los ua thawj qhov tseem ceeb hauv keeb kwm ntawm kev tsim kho tshuab huv. .

Nyob rau hauv nruab nrab-1960s, chav huv huv hauv cov chaw ua haujlwm xws li cov tshuab hluav taws xob hauv Tebchaws Meskas tau tshwm sim zoo li cov nceb tom qab los nag, thiab tib lub sijhawm pib cov txheej txheem ntawm kev hloov cov tshuab ntxhua khaub ncaws rau hauv chav huv huv. Xyoo 1961, laminar flow (unidirectional flow) cleanroom tau yug los. Lub ntiaj teb thawj chav huv huv tshaj plaws-lub US Air Force Technical Regulations 203 tau tsim.

Thaum xyoo 1970s, lub hom phiaj ntawm kev tsim kho chav huv tau pib hloov mus rau kev kho mob, tshuaj, zaub mov thiab kev lag luam biochemical. Ntxiv rau Tebchaws Meskas, lwm lub tebchaws muaj kev lag luam siab heev, xws li Nyiv, Lub Tebchaws Yelemees, Tebchaws Askiv, Fabkis, Switzerland, yav dhau los Soviet Union, thiab Netherlands, kuj tau txuas ntxiv qhov tseem ceeb rau thiab siv zog tsim kev siv thev naus laus zis.

Tom qab xyoo 1980s, Tebchaws Asmeskas thiab Nyij Pooj tau ua tiav kev tsim cov lim dej ultra-high efficiency tshiab nrog cov khoom pom ntawm 0.1μm thiab kev ntes tau ntawm 99.99%. Thaum kawg, ultra-high-theem huv chav ntawm 0.1μm qib 10 thiab 0.1μm theem 1 tau tsim, uas coj kev txhim kho ntawm chav huv huv rau hauv lub sijhawm tshiab.

Hauv tsev

Los ntawm thaum ntxov 1960s mus rau lig 1970s, kaum xyoo no yog pib thiab lub hauv paus theem ntawm Tuam Tshoj tus cleanroom technology. Nws yog kwv yees li kaum xyoo tom qab lub teb chaws txawv teb chaws. Nws yog lub sijhawm tshwj xeeb thiab nyuaj heev, nrog kev lag luam tsis muaj zog thiab tsis muaj kev sib tham nrog cov tebchaws muaj zog. Raws li cov xwm txheej nyuaj, nyob ib puag ncig cov kev xav tau ntawm cov tshuab precision, cov cuab yeej aviation thiab hluav taws xob hauv kev lag luam, Tuam Tshoj cov neeg ua haujlwm huv tshuab tau pib lawv txoj kev ua lag luam.

Txij xyoo 1970s mus txog rau xyoo 1980s, lub sijhawm kaum xyoo no, Tuam Tshoj txoj kev siv thev naus laus zis tau ntsib lub hnub ci kev loj hlob. Nyob rau hauv txoj kev loj hlob ntawm Tuam Tshoj tus cleanroom technology, ntau landmark thiab tseem ceeb achievements twb yuav luag yug nyob rau hauv no theem. Cov ntsuas tau mus txog qib kev kawm ntawm txawv teb chaws hauv xyoo 1980s.

Txij li thaum xyoo 1990, Tuam Tshoj txoj kev lag luam tau tswj hwm kev ruaj ntseg thiab kev loj hlob sai, nrog kev nqis peev thoob ntiaj teb txuas ntxiv, thiab ntau pawg neeg sib txawv tau ua tiav ua tiav ntau lub chaw tsim khoom microelectronics hauv Suav teb. Yog li ntawd, cov cuab yeej siv hauv tsev thiab cov kws tshawb fawb muaj ntau lub sijhawm los ncaj qha rau cov qauv tsim qauv ntawm chav ua haujlwm siab txawv teb chaws, nkag siab txog lub ntiaj teb cov cuab yeej siv siab heev thiab cov cuab yeej siv, kev tswj hwm thiab kev saib xyuas, thiab lwm yam.

Nrog rau txoj kev loj hlob ntawm kev tshawb fawb thiab thev naus laus zis, Tuam Tshoj cov chaw ua haujlwm huv huv kuj tau tsim kho sai heev.

Raws li tib neeg txoj kev ua neej nyob txuas ntxiv txhim kho, lawv cov kev xav tau rau kev nyob ib puag ncig thiab kev ua neej zoo tau nce siab dua, thiabchav huvengineering thev naus laus zis tau maj mam siv rau hauv tsev kom huv huv. Tam sim no,Tuam Tshoj's chav huvengineering tsis yog tsuas yog siv rau cov khoom siv hluav taws xob, khoom siv hluav taws xob, tshuaj, khoom noj, kev tshawb fawb thiab lwm yam kev lag luam, tab sis kuj tseem yuav txav mus rau hauv tsev, kev lom zem rau pej xeem thiab lwm qhov chaw, cov tsev kawm ntawv, thiab lwm yam. Kev txhim kho kev tshawb fawb thiab thev naus laus zis tau maj mam nce.chav huvengineering tuam txhab uas muag rau ntau txhiab tsev neeg, thiab cov nplai ntawm domesticchav huvkev lag luam kuj tau loj hlob, thiab tib neeg tau pib maj mam txaus siab rau cov teebmeem ntawmchav huvengineering.
