Cov kua nplaum UV puas zoo los tsis zoo?

Cov kua nplaum uv yog dab tsi?

Lo lus "UV kua nplaum" feem ntau yog hais txog cov kua nplaum uas tsis muaj duab ntxoov ntxoo, tseem hu ua cov kua nplaum uas rhiab heev rau lub teeb lossis cov kua nplaum uas kho tau los ntawm lub teeb ultraviolet. Cov kua nplaum UV yuav tsum tau kho los ntawm kev raug lub teeb ultraviolet thiab siv tau rau kev sib txuas, pleev xim, txheej, thiab lwm yam kev siv. Lub npe luv "UV" sawv cev rau Ultraviolet Rays, uas yog cov hluav taws xob electromagnetic uas tsis pom nrog cov wavelengths xws li 110 txog 400nm. Lub hauv paus ntsiab lus tom qab kev kho cov kua nplaum UV uas tsis muaj duab ntxoov ntxoo yog kev nqus lub teeb ultraviolet los ntawm cov photoinitiators lossis photosensitizers hauv cov khoom siv, ua rau muaj cov free radicals lossis cations uas pib polymerization thiab kev sib txuas lus hauv ob peb feeb xwb.

 

Cov txheej txheem nplaum nplaum tsis muaj duab ntxoov ntxoo: cov kua nplaum tsis muaj duab ntxoov ntxoo tseem hu ua kua nplaum ultraviolet, nws yuav tsum tau ua los ntawm kev siv ultraviolet irradiation rau cov kua nplaum hauv qab lub hauv paus ntawm kev kho, uas yog, cov photosensitizer hauv cov kua nplaum tsis muaj duab ntxoov ntxoo thiab kev sib cuag nrog lub teeb ultraviolet yuav sib txuas nrog lub monomer, theoretically tsis muaj kev cuam tshuam ntawm lub teeb ultraviolet, cov kua nplaum tsis muaj duab ntxoov ntxoo yuav luag tsis kho. Qhov ceev ntawm UV kho muaj zog, lub sijhawm kho sai dua li ntawm 10-60 vib nas this. Cov kua nplaum tsis muaj duab ntxoov ntxoo yuav tsum tau ci los ntawm lub teeb kom kho, yog li cov kua nplaum tsis muaj duab ntxoov ntxoo siv rau kev sib txuas feem ntau tsuas yog sib txuas rau ob yam khoom pob tshab lossis ib qho ntawm lawv yuav tsum pob tshab, yog li lub teeb ultraviolet tuaj yeem hla dhau thiab irradiate rau ntawm cov kua nplaum.

 

Cov yam ntxwv ntawm UV kua nplaum

1. Kev tiv thaiv ib puag ncig / kev nyab xeeb

Tsis muaj VOC volatiles, tsis muaj kuab paug rau huab cua ib puag ncig; cov khoom xyaw nplaum tsis txwv lossis txwv tsis pub ua raws li cov cai ib puag ncig; tsis muaj kuab tshuaj, tsis tshua muaj hluav taws

2. Siv tau yooj yim thiab txhim kho kev ua haujlwm kom zoo dua qub

Qhov ceev kho yog ceev thiab tuaj yeem ua tiav hauv ob peb vib nas this mus rau kaum vib nas this, uas yog qhov zoo rau cov kab ntau lawm thiab txhim kho kev ua haujlwm. Tom qab kho, nws tuaj yeem kuaj xyuas thiab thauj mus los, txuag qhov chaw. Kev kho ntawm chav tsev kub txuag hluav taws xob, xws li kev tsim cov nplaum uas rhiab heev rau lub teeb 1g. Lub zog xav tau tsuas yog 1% ntawm cov nplaum dej sib xws thiab 4% ntawm cov nplaum uas muaj kuab tshuaj. Nws tuaj yeem siv rau cov ntaub ntawv uas tsis haum rau kev kho kub siab. Lub zog siv los ntawm kev kho ultraviolet tuaj yeem txuag tau 90% piv rau cov tshuaj kho thermal. Cov khoom siv kho yog yooj yim thiab tsuas yog xav tau teeb lossis siv txoj siv conveyor. Txuag qhov chaw; ib qho system, tsis tas yuav sib tov, yooj yim siv.

3. Kev Sib Haum Xeeb

Cov ntaub ntawv rhiab heev rau qhov kub thiab txias, cov kuab tshuaj thiab cov dej noo siv tau.

Tswj qhov kev kho kom qhuav, lub sijhawm tos tuaj yeem hloov kho, qib kev kho kom qhuav tuaj yeem hloov kho. Cov kua nplaum tuaj yeem siv ntau zaus rau ntau qhov kev kho kom qhuav. Lub teeb UV tuaj yeem yooj yim ntsia rau hauv cov kab ntau lawm uas twb muaj lawm yam tsis muaj kev hloov pauv loj.

4. Muaj ntau yam kev siv thiab kev sib txuas zoo

Cov kua nplaum UV muaj ntau yam kev siv thiab muaj cov teebmeem zoo heev ntawm cov yas thiab ntau yam khoom siv. Nws muaj lub zog sib txuas siab thiab tuaj yeem rhuav lub cev yas yam tsis muaj kev tshem tawm los ntawm kev sim rhuav tshem. Cov kua nplaum UV tuaj yeem tso rau hauv ob peb feeb xwb, thiab ncav cuag qhov muaj zog siab hauv ib feeb;

Tom qab kho tas, nws pob tshab tag, thiab cov khoom yuav tsis daj lossis dawb ntev. Piv nrog rau cov nplaum nplaum ib txwm muaj, nws muaj qhov zoo ntawm kev tiv thaiv ib puag ncig, tsis muaj kev dawb, yooj ywm zoo, thiab lwm yam. Nws muaj qhov kub qis, kub siab thiab av noo zoo heev.
