Thaum "Dej" dhau los ua siab heev -Cov Khoom Raw Precision
Nyob rau hauv lub neej txhua hnub, dej yog lub hauv paus ntawm lub neej; tab sis nyob rau hauv lub realm ntawm kev txiav -ntug tshuab, nws yog deb tshaj qhov ntawd -nws yog ib qho tseem ceeb raw khoom uas yog engineered precisely thiab tswj.Los ntawm cov chips uas tsav lub ntiaj teb digital, mus rau cov chaw muag tshuaj uas tiv thaiv tib neeg kev noj qab haus huv, mus rau hluav taws xob uas teeb pom kev hauv tsev suav tsis txheeb, lawv cov ntsiab lus thiab cov kev xav tau rau "dej ntshiab" yog lub ntiaj teb sib nrug. Niaj hnub no, peb yuav delve rau hauv yuav ua li casOb npaug -Theem Rov Qab Osmosis (Ob chav-theem RO) thev naus laus zis,Raws li cov txheej txheem yooj yim thiab muaj zog, ua tau raws li cov kev xav tau ntawm cov dej zoo tshaj plaws ntawm peb qhov kev lag luam tseem ceeb.
► I. Qhov "Purity" Cornerstone ntawm Semiconductor Kev Lag Luam: Kev Ua Haujlwm ntawm Lub Ntiaj Teb Qhov Kawg Microscopic
► Qhov Kev Sib Tw: Vim li cas ib qho dej "tsis huv" tuaj yeem rhuav tshem cov nti tseem ceeb?
Nyob rau hauv lub ntiaj teb microscopic ntawmsemiconductor manufacturing, tshwj xeebwafer ntau lawm, tej minuscule impurity tuaj yeem dhau los ua "loj heev." Ions, tag nrho cov organic carbon (TOC), thiab txawm infinitesimal hais nyob rau hauv dej, yog hais tias sab laug nyob rau hauv nti circuits uas yog kaum tawm txhiab lub sij hawm thinner tshaj ib tug tib neeg cov plaub hau, yuav ua rau luv luv Circuit Court los yog kev ua hauj lwm tsis xws luag, ua rau poob nyiaj txiag loj heev. "Purity" ntawm no txhais tau hais tias nyob ze ze rau qhov theoretically ntshiab dej, nrog rau kev zam rau impurities ntsuas nyob rau hauv ib feem ntawm billion (ppb) los yog ib feem ntawm trillion (ppt).
► Txoj Kev: Yuav ua li cas lub semiconductor thim rov qab osmosis system ua haujlwm hauv kev sib koom ua ke?
Kev ua tau zoo Ultrapure Dej (UPW) system yog lub neej ntawm cov khoom siv hluav taws xob, thiab Ob chav -theem RO system yog lub plawv ntawm lub neej no. Nws feem ntau ua haujlwm raws li hauv qab no: thawj -theem RO system ua qhov kev ua kom huv ntawm cov dej nyoos, tshem tawm feem ntau ntawm ions thiab impurities; Tom qab ntawd, cov permeate los ntawm thawj theem ua hauj lwm raws li cov dej pub rau lub thib ob -theem RO rau txawm tob purification. Qhov kev tsim tandem no zoo heev txhim kho cov ntsev tsis kam lees thiab qhov zoo ntawm cov khoom dej.
Txawm li cas los xij, RO units ib leeg tsis txaus los ua kom tau raws li qhov xav tau kawg. Ib qho ua tiav UPW system RO kev daws teeb meem suav nrogkev sib xyaw ua ke ntawm ob chav -theem RO nrog cov thev naus laus zis xws li Electrodeionization (EDI), ultraviolet (UV) sterilization, degasification membranes, thiab polishing kawg.Qhov Ob -theem RO muab qhov ruaj khov, siab siab- dej pub rau cov EDI tom ntej, ua rau lawv "polish" cov dej zoo dua, tshem tawm cov kab ions, thiab thaum kawg tso cai rau cov khoom siv dej tsis tu ncua mus txog qhov kev txwv ntawm 18.2 MΩ·cm. Cov txheej txheem kev sib cuam tshuam no ua kom ntseeg tau tias txhua qhov dej xa mus rau cov kab ntau lawm yog qhov tsis huv.
► II. Biopharmaceuticals '" Dej rau lub neej ": Cov qauv nruj rau kev nyab xeeb thiab ua raws
► Qhov Kev Sib Tw: Hauv kev tshawb fawb txog lub neej, dej ntshiab txhais li cas?
Hauvkev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv kev npaj ntawmDej rau Txhaj Tshuaj (WFI), qhov purity ntawm dej yog ncaj qha cuam tshuam rau cov neeg mob kev nyab xeeb. Cov teeb meem tseem ceeb ntawm no, dua li tshem tawm cov pa impurities, pw hauv kev tswj hwm nruj ntawm cov khoom tsim kev puas tsuaj rau tib neeg lub cev, xws li cov kab mob thiab cov pyrogens (endotoxins). Lub kaw lus dej yuav tsum nruj me ntsis ua raws li Kev Tswj Xyuas Kev Tswj Xyuas Zoo (GMP), thiab txhua qhov kev sib txawv me me tuaj yeem ua rau cov khoom paug thiab kev tswj xyuas tsis raug.
► Kev daws: Kev tsim qauv huv huv lub tswv yim ntawm kev rov qab osmosis kws tshuaj
Daim ntawv thov ntawm Ob -theem RO hauv kev lag luam kws tshuaj ua raws li kev tsim lub tswv yim tsim qhov sib txawv ntawm qhov hauv cov khoom siv hluav taws xob, nrog rau kev ua kom muaj kev nyab xeeb ntau dua. A GMP-raws li WFI cov txheej txheem tsim khoom muaj "sterility" thiab "kev yooj yim ntawm kev siv tau zoo" kos rau hauv nws cov DNA txij thaum pib ntawm nws qhov tsim.
Ua ntej,lub kaw lus feem ntau yog tsim los ntawm qib siab - qib huv huv stainless hlau,nrog rau tag nrho cov kav dej thiab cov kev sib txuas tshwj xeeb tau kho kom zoo nkauj sab hauv thiab tsis muaj ob txhais ceg tuag, tiv thaiv kev muaj peev xwm ntawm microbial kev loj hlob thiab tsim biofilm. Qhov thib ob, Qhov Ob -theem RO membranes lawv tus kheej muaj peev xwm tsis lees paub lub cev zoo rau cov khoom loj xws li cov kab mob, kab mob, thiab pyrogens. Ob -theem series filtration mechanism tsim ib qho yuav luag insurmountable barrier. Tsis tas li ntawd, lub kaw lus tseem koom ua ke hauv online dej kub tshuaj tua kab mob lossis kev ua haujlwm pasteurization, tso cai rau lub sijhawm ua kom tsis muaj menyuam ntawm tag nrho cov kab ke. Qhov no ua kom muaj kev huv tsis tu ncua ntawm tag nrho cov kev kho dej thiab kev faib cov voj voog, pab cov tuam txhab muag tshuaj ntseeg siab rau kev soj ntsuam nruj tshaj plaws.
► BAB III. Lub "Power Lifeline" ntawm Kev Lag Luam Hluav Taws Xob: Ua kom ruaj khov ua haujlwm ntawm lub zog lub plawv
► Qhov Kev Sib Tw: Vim li cas boilers thiaj li "tshwj xeeb" txog dej zoo?
Hauv thermal lossis nuclear fais fab nroj tsuag, siab -siab boilers yog "lub plawv" uas tsav lub chav turbines rau lub zog tsim. Yoglub boiler feedwatermuaj cov ntsev ntau dhau, tshwj xeeb tshaj yog hardness thiab silica, lawv yuav sai sai tsim cov nplai nyob rau hauv qhov kub thiab txias, ua rau muaj kev cuam tshuam loj heev rau kev hloov hluav taws xob thiab ua rau muaj kev nyab xeeb. Ib yam li ntawd, corrosive ions hauv dej, xws li chloride ions, tuaj yeem ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob kim kim. Yog li ntawd, boiler feedwater yuav tsum yog cov dej ntshiab heev demineralized.
► Kev daws: Kev sib koom ua ke golden ntawm kev rov qab osmosis rau boiler pub dej thiab EDI
Yuav kom ua tau raws li qhov xav tau ntawm kev lag luam hluav taws xob, cov txheej txheem dej demineralized cog feem ntau siv txoj hauv kev uasua ke Ob npaug -theem RO nrog EDI. Qhov kev sib xyaw ua ke no tau qhuas tias yog "kev koom tes kub" rau kev ua haujlwm ruaj khov ntawm boilers. Ob chav -theem RO system, raws li lub hauv paus tseem ceeb rau ua ntej -demineralization, tshem tawm cov ntsev feem ntau yaj thiab silica, uas yog qhov tsis zoo rau boilers.
Tom qab raug kho los ntawm Ob -theem RO, cov dej ntsev cov ntsiab lus twb tsawg heev, tsim kom muaj qhov chaw ua haujlwm zoo tshaj plaws rau EDI modules tom ntej. EDI tom qab ntawd coj mus ua kom tiav txoj haujlwm sib sib zog nqus demineralization kawg, ua kom muaj - dej demineralized zoo. Cov txheej txheem no tsis yog tsuas yog xa cov dej zoo thiab ruaj khov, tab sis kuj txo qis lossis txawm tias tag nrho tshem tawm cov teeb meem ib puag ncig thiab kev nyab xeeb kev nyab xeeb cuam tshuam nrog cov kua qaub thiab alkali rov tsim dua tshiab uas yuav tsum tau ua hauv cov txheej txheem kev sib pauv ion tsoos. Nws zoo txuas ntxiv cov tshuaj ntxuav lub voj voog ntawm lub boiler, txhim kho lub zog tsim hluav taws xob, thiab muab kev lav zoo rau kev ruaj khov ntawm lub zog.

Los ntawm qhov kawg purity yuav tsum tau rau kev tsim microchips, mus rau lub meej sterility rau kev npaj injectables, mus rau lub ruaj khov kev cia siab rau tsav tsheb fais fab units,Muab ob npaug rau-theem RO thev naus laus zis ua kom pom nws qhov kev hloov pauv tau zoo thiab tus nqi tseem ceeb. Nws tsis yog ib qho ntawm cov khoom siv tab sis lub platform thev naus laus zis uas tuaj yeem raug teeb tsa raws li cov kev xav tau ntawm cov kev lag luam sib txawv, ua pov thawj tias nyob rau hauv niaj hnub high - thev naus laus zis sectors, kev tswj xyuas kom zoo ntawm cov dej yog lub zog tseem ceeb ntawm kev txhim kho thev naus laus zis thiab ua kom muaj kev ruaj ntseg ntau lawm.
