Lub sij hawm yoov! Nws’s twb caij ntuj no thiab ntau tus neeg muas zaub tsis ntev los no hu rau peb txog yuav ua li cas dilute lub anti-freezer thiab yuav ua li cas thaum lub laser dej chiller tsis siv rau lub caij ntuj no ntev. Tab sis ua ntej, cia’s tau paub txog kev paub txog kev tiv thaiv lub freezer.
Lub hom phiaj ntawm anti-freezer
Anti-freezer, raws li nws lub npe qhia, tuaj yeem tiv thaiv cov dej hauv lub voj voog ncig los ntawm kev khov kom cov kav dej sab hauv yuav tsis nthuav thiab tawg vim cov dej khov. Muaj ntau ntau yam sib txawv thiab txawv qauv ntawm anti-freezers nyob rau hauv kev ua lag luam, uas yog heev dazzling. Yog li ntawd, ntau tus neeg siv khoom tsis ua’t paub xaiv dab tsi los yog yuav ua li cas rau dilute anti-freezers. Qee cov neeg siv khoom txawm xaiv qee qhov kev tiv thaiv lub freezers uas tsis haum rau peb cov dej chiller.
Kev ua tau zoo yuav tsum tau ua los tiv thaiv lub freezer hauv lub chiller
Peb cov dej chiller muaj qee yam kev ua tau zoo ntawm cov khoom siv los tiv thaiv lub freezer. Hom tsis raug lossis siv tsis tsim nyog los tiv thaiv lub freezer yuav ua rau kev puas tsuaj ntawm cov kav dej sab hauv. Cov kev ua tau zoo ntawm kev tiv thaiv lub freezer yog raws li nram no:
1.Stable tshuaj ua haujlwm;
2.Kev ua haujlwm zoo los tiv thaiv khov;
3.Relatively tsawg-kub viscosity;
4.Anti-corrosion thiab xeb tiv thaiv;
5.Tsis muaj qhov o lossis xeb ntawm lub raj roj hmab kaw
Hauv tsev thiab txawv teb chaws, dej raws li lub freezers uas muaj ethylene glycol lossis propylene glycol feem ntau yog siv. Cov hom tshuaj tiv thaiv no tuaj yeem siv tau tom qab diluted raws li qee qhov kev faib ua feem.
Raws li rau leej niam cov tshuaj ntawm anti-freezer uas yog hom concentrated tsis tuaj yeem siv ncaj qha. Nws yuav tsum tau diluted nrog softened dej rau tej yam concentration raws li qhov kub thiab txias yuav tsum tau. Tam sim no peb tab tom yuav ua kom paub ob qho ntawm feem ntau siv los tiv thaiv lub freezers.
Ethylene glycol concentration daim ntawv
Los ntawm daim ntawv saum toj no, peb tuaj yeem pom tias qhov chaw khov ntawm ethylene glycol anti-freezer yuav hloov raws li nws cov concentration hloov. Thaum lub ntim concentration qis dua 56%, qhov chaw khov yuav qis dua thaum cov concentration nce. Txawm li cas los xij, thaum lub ntim concentration siab dua 56%, qhov chaw khov yuav dhau los ua siab dua thaum cov concentration nce. Thaum lub ntim concentration nce mus txog 100%, lub khov taw tes mus txog -13 degree C. Yog vim li cas vim li cas thiaj li concentrated hom anti-freezer tsis tuaj yeem muab ntxiv rau hauv lub chiller ncaj qha.
P.S. Rau qee yam ntawm cov khoom siv laser, lawv yuav muaj qee qhov yuav tsum tau ua rau cov khoom tiv thaiv lub freezer. Yog li ntawd, nws yog pom zoo kom sab laj nrog lub laser qhov chaw tsim tshuaj paus ua ntej ntxiv.
Propylene glycol concentration daim ntawv
Raws li rau cov propylene glycol, qhov ntim concentration - khov taw tes sib txheeb zoo ib yam li ethylene glycol.
3 lub hauv paus ntsiab lus ntawm kev siv tshuaj tiv thaiv lub freezer
1.Qhov qis dua qhov concentration zoo dua
Feem ntau ntawm cov anti-freezer yog corrosive. Anti-freezer nrog ntau dua 30% uas muaj ethylene glycol yuav ua rau txo qis kev ua haujlwm ntawm qee yam ntawm cov khoom siv laser thiab tshaj tawm qhov muaj feem cuam tshuam rau stainless hlau dej twj tso kua mis lub cev muaj zog tshuab foob. Yog li ntawd, thaum ua tau raws li qhov xav tau los tiv thaiv kev ua haujlwm khov, qhov qis qis dua qhov zoo dua.
2.Qhov siv sijhawm luv dua qhov zoo dua
Tom qab siv rau qee lub sijhawm, kev tiv thaiv lub freezer zoo li yuav deteriorate. Thiab lub deteriorated anti-freezer yog ntau corrosive nrog ntau dua viscosity. Yog li ntawd, nws yog pom zoo kom hloov tawm lub anti-freezer ib ntus thiab lub tswv yim hloov zaus yuav yog ib xyoos ib zaug. Thaum lub caij ntuj sov, peb siv dej huv. Thaum lub caij ntuj no, peb hloov tawm qhov tshiab los tiv thaiv lub freezer.
3.Tsis txhob sib tov ntau hom kev tiv thaiv lub freezers
Nws raug nquahu kom siv tib hom thiab tib hom tshuaj tiv thaiv lub freezer. Tias yog vim hais tias txawm ntau hom kev tiv thaiv lub freezer muaj tib cov khoom xyaw, lawv cov additives yuav txawv. Kev sib xyaw ntawm ntau hom kev tiv thaiv lub freezers tuaj yeem ua rau cov tshuaj tiv thaiv kab mob, ua rau npuas lossis xaim.
