一.Lub hauv paus ntsiab lus thiab txoj kev ntawm antifreeze
Cov kua dej muaj "kwv yees". Thaum qhov kub ntawm cov kua qis dua qhov khov no, nws yuav ua kom muaj zog, thiab qhov ntim ntawm cov dej deionized thiab cov dej distilled yuav nce ntxiv thaum lub sij hawm solidification txheej txheem, uas yuav ua rau cov dej-txias tubing thiab sealing txuas, ces ua kev puas tsuaj.
Txhawm rau kom tsis txhob muaj kev puas tsuaj ntawm lub raj laser, lub taub hau tso zis, thiab cov dej txias uas tshwm sim los ntawm kev ua kom muaj zog ntawm cov kua txias, muaj 3 qhov kev tiv thaiv hauv qab no:
1.Raws li qhov xwm txheej yuav tsis muaj hluav taws xob hauv zos, lub tshuab dej txias yuav tsis raug kaw thaum hmo ntuj. Nyob rau tib lub sijhawm, hauv kev xav txog kev txuag hluav taws xob, thov kho qhov kub thiab txias ntawm cov dej kub ib txwm mus rau 5-10 Celsius degrees kom ntseeg tau tias cov coolant nyob rau hauv lub circulating lub xeev thiab qhov kub tsis qis tshaj qhov khov. .
2.Thaum cov khoom siv tsis siv lub sijhawm ntev, tso cov dej txias hauv lub laser thiab cov dej txias, thiab tom qab ntawd siv cov cua compressed kom ntws cov dej txias hauv cov dej txias thiab lub laser.Thiab tib lub sijhawm, dej. nyob rau hauv lub twj tso kua mis dej thiab lub lim dej txias yuav tsum tau drained.
3.Ntxiv ib qho kev faib ua feem ntawm cov tshuaj tiv thaiv kab mob rau lub chiller: thaum siv ib puag ncig feem ntau siv hluav taws xob los yog tsis muaj cov xwm txheej kom ntws cov dej txias txhua hnub, cov tshuaj tiv thaiv yuav tsum tau siv.
Lub hauv paus kua ntawm antifreeze feem ntau yog tsim los ntawm cawv thiab dej, uas yuav tsum tau kub boiling point thiab flash point, siab tshwj xeeb kub thiab conductivity, tsis tshua muaj kub viscosity, tsis yooj yim rau ua npuas ncauj, thiab tsis corrode hlau qhov chaw, roj hmab hoses, thiab lwm yam. Thaum xaiv los yog npaj cov tshuaj tiv thaiv kab mob, nws qhov chaw khov yuav tsum yog li 5 Celsius degrees qis dua qhov qis tshaj qhov kub ntawm qhov chaw ua haujlwm.
2.Qhov kev xaiv ntawm antifreeze
Siv cov tshuaj tiv thaiv tshwj xeeb ntawm cov khoom lag luam, tsis txhob siv ethanol hloov.
Nws raug pom zoo kom siv DowthemSR-1 cov khoom uas sawv cev los ntawm Dow Chemical lossis CLARIANT hom.
Muaj ob hom antifreeze haum rau siv nyob rau hauv laser tshuab:
1.Antifrogen N (Glycol-water type)
2.Antifrogen L (Propylene Glycol-Dej Hom)
Nco tseg:
1.Tsis muaj tshuaj tua kab mob tuaj yeem hloov cov dej deionized thiab tsis tuaj yeem siv rau lub sijhawm ntev hauv ib xyoos. Tom qab lub caij ntuj no, cov kab dej txias yuav tsum tau ntxuav nrog dej deionized lossis dej distilled, thiab siv cov dej deionized thiab cov dej distilled li cov kua dej txias yuav tsum rov pib dua.
2.Tsis txhob siv tshuaj tua kab mob ncaj qha, nws yuav tsum tau tov nrog dej distilled lossis dej deionized.
3.Thaum pib, thawj zaug tig lub chiller kom khiav li ntawm 10-20 feeb, tos kom qhov kub ntawm lub chiller nce mus rau qhov ntsuas kub kom haum rau lub laser, thiab tom qab ntawd pib tawm lub laser.

Antifreeze siv piv siv
(Qhov piv yuav tsum yog nyob ntawm qhov ntsuas qhov tsawg kawg nkaus hauv zos)
Qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus hauv cheeb tsam
6: 4 (60% antifreeze, 40% dej) -42 degree --45 degree
5: 5 (50% antifreeze, 50% dej) -32 degree --35 degree
4: 6 (40% antifreeze, 60% dej) -22 degree --25 degree
3: 7 (30% antifreeze, 70% dej) -12 degree --15 degree
2:8 (20% antifreeze, 80% dej) -02 degree --05 degree
