UV Technology – Medium Pressure vs. Low Pressure. Qhov twg zoo dua?
Thaum ntsuam xyuas cov khoom siv UV, nws tuaj yeem nyuaj heev kom nkag siab qhov sib txawv ntawm cov tuam ntxhab, thev naus laus zis, thiab kev ua haujlwm ntawm lub cev. Txij li cov khoom siv UV zoo li yuav kav ntev li 15-20 xyoo, ntau tus neeg yuav khoom thiab cov kws tsim qauv qhia cov khoom siv, yuav tsis nkag siab txhua qhov sib txawv, vim nws tsis yog ib yam khoom uas yuav tsum tau rov ntsuam xyuas tas li thiab hloov.
Thaum UV cov tuam txhab xa mus rau qhov nruab nrab siab lossis cov cuab yeej siv hluav taws xob tsawg, lub sij hawm siab yog siv rau cov roj siab hauv lub teeb thiab tsis yog lub zog ua haujlwm siab hauv cov kav dej. Ob lub thev naus laus zis tuaj yeem tswj qhov kev ua haujlwm siab sib npaug.
Thaum nruab nrab siab UV thev naus laus zis tau qhia, qhov kev nce qib tseem ceeb yog lub peev xwm los tsim cov teeb uas yuav muaj qhov tso zis ntau dua rau ib lub teeb dua li cov teeb hluav taws xob tsawg. Kev lag luam nruab nrab siab UV tshuab tuaj yeem tso tawm kwv yees li 10 npaug ntawm lub zog ib lub teeb dua li cov teeb hluav taws xob qis UV. Qhov no muab cov tshuaj tua kab mob ntau dua nyob rau hauv ib lub nkoj UV, tsis tas yuav ntxiv ntau lub teeb kom ua tiav cov tshuaj tua kab mob siab, raws li qhov xav tau nrog cov tshuab qis. Yog li ntawd, kev siv tshuab siab nruab nrab siv lub teeb tsawg dua, muaj cov hneev taw me me, yuav tsum muaj kev saib xyuas tsawg dua, thiab yuav tsum tau siv tsawg dua tag nrho.
Nws tau pom ntau xyoo uas qhov nruab nrab siab UV thev naus laus zis nyiam muab qib siab dua ntawm kev ua haujlwm ntawm cov kab mob ntau dua li qhov tsis tshua muaj siab UV (txawm tias nyob rau qib sib npaug), vim yog cov zis polychromatic ntawm nruab nrab siab UV. Qhov no polychromatic tso zis tso cai rau nruab nrab siab UV kom inactivate kab mob los ntawm protein degradation thiab enzymatic tawg, ntxiv rau DNA puas. Nws tau raug pom tias qee hom kab mob (xws li adenovirus), yuav tsum tau 1.5 npaug ntawm cov koob tshuaj uas tsis tshua muaj siab UV thev naus laus zis piv rau nruab nrab siab UV, rau qib sib npaug ntawm kev tsis ua haujlwm.
Qhov teeb meem loj tshaj plaws ntawm qhov nruab nrab siab piv rau qhov tsis tshua muaj siab yog tias lub teeb tsis muaj zog thiab siv zog ntau dua txhawm rau muab cov tshuaj tua kab mob tib yam. Tsis tas li ntawd, vim tias qhov tso zis ntau tshaj ib lub teeb ntawm nruab nrab lub zog siab, lawv tuaj yeem xav tau cov txheej txheem ntxiv los ua kom cov cua sov uas tsim tawm, tshwj xeeb tshaj yog thaum lub sijhawm xoom ntws. Yog li ntawd, kev txiav txim siab seb qhov system twg zoo tshaj plaws, nyob ntawm ntau yam ntawm cov txheej txheem thiab daim ntawv thov.
