Lub sijhawm dhau mus sai heev! Tam sim no yog lub caij ntuj no lawm thiab ntau tus neeg siv khoom tsis ntev los no hu rau peb txog yuav ua li cas kom cov tshuaj tiv thaiv khov thiab yuav ua li cas thaum lub tshuab cua txias laser tsis siv ntev hauv lub caij ntuj no. Tab sis ua ntej, cia peb paub txog cov kev paub yooj yim txog cov tshuaj tiv thaiv khov.
Cov tshuaj tiv thaiv kev khov, raws li nws lub npe qhia, tuaj yeem tiv thaiv cov dej hauv lub voj voog kom tsis txhob khov kom cov kav dej sab hauv yuav tsis nthuav dav thiab tawg vim yog dej khov. Muaj ntau hom thiab ntau hom tshuaj tiv thaiv kev khov hauv khw, uas yog qhov zoo nkauj heev. Yog li ntawd, ntau tus neeg siv khoom tsis paub yuav xaiv dab tsi lossis yuav ua li cas kom cov tshuaj tiv thaiv kev khov tsis yaj. Qee tus neeg siv khoom txawm xaiv qee cov tshuaj tiv thaiv kev khov uas tsis haum rau peb lub tshuab dej txias.
Peb lub tshuab dej txias muaj qee yam kev cai ua haujlwm ntawm cov khoom siv tiv thaiv kev khov. Hom tsis raug lossis siv cov khoom siv tiv thaiv kev khov tsis raug yuav ua rau cov kav dej sab hauv puas tsuaj. Cov kev cai ua haujlwm rau cov khoom siv tiv thaiv kev khov yog raws li nram no:
1. Kev ua haujlwm tshuaj ruaj khov;
2. Kev ua haujlwm zoo tiv thaiv kev khov;
3. Qhov viscosity qis qis uas tsis tshua muaj qhov kub thiab txias;
4. Tiv thaiv kev xeb thiab xeb;
5. Tsis muaj o lossis xeb ntawm lub raj roj hmab kaw
Nyob hauv tsev thiab txawv teb chaws, feem ntau siv cov tshuaj tiv thaiv kev khov dej uas muaj ethylene glycol lossis propylene glycol. Cov tshuaj tiv thaiv kev khov no siv tau tom qab diluted raws li qhov sib piv.
Hais txog cov tshuaj tiv thaiv khov uas yog hom concentrated, siv tsis tau ncaj qha. Yuav tsum tau dilute nrog dej mos kom txog thaum nws muaj concentration raws li qhov kub thiab txias xav tau. Tam sim no peb yuav qhia txog ob hom tshuaj tiv thaiv khov uas siv ntau.
Daim ntawv qhia txog Ethylene glycol
Los ntawm daim ntawv saum toj no, peb tuaj yeem pom tias qhov chaw khov ntawm ethylene glycol anti-freezer yuav hloov pauv raws li nws qhov kev hloov pauv. Thaum qhov ntim concentration qis dua 56%, qhov chaw khov yuav qis dua thaum qhov concentration nce ntxiv. Txawm li cas los xij, thaum qhov ntim concentration siab dua 56%, qhov chaw khov yuav siab dua thaum qhov concentration nce ntxiv. Thaum qhov ntim concentration ncav cuag 100%, qhov chaw khov ncav cuag -13 degree C. Yog vim li cas cov tshuaj concentrated anti-freezer tsis tuaj yeem ntxiv rau hauv lub tshuab txias ncaj qha.
PS Rau qee hom laser sources, lawv yuav muaj qee yam kev cai rau cov tshuaj tiv thaiv freezer. Yog li ntawd, nws raug pom zoo kom sab laj nrog lub chaw tsim khoom laser ua ntej ntxiv.
Daim ntawv qhia txog propylene glycol
Raws li rau propylene glycol, qhov concentration ntawm qhov ntim - qhov khov ntawm qhov sib piv zoo ib yam li ethylene glycol.
1. Qhov qis dua qhov concentration zoo dua
Feem ntau ntawm cov tshuaj tiv thaiv kev khov yog xeb. Cov tshuaj tiv thaiv kev khov uas muaj ntau dua 30% uas muaj ethylene glycol yuav ua rau qee hom laser ua haujlwm tsis zoo thiab muaj kev pheej hmoo rau lub tshuab foob dej ntawm lub twj tso kua mis stainless hlau. Yog li ntawd, thaum ua tau raws li qhov yuav tsum tau ua kom tsis txhob khov, qhov concentration qis dua qhov zoo dua.
2. Lub sijhawm luv dua siv qhov zoo dua
Tom qab siv tau ib lub sijhawm, cov tshuaj tiv thaiv kev khov yuav lwj. Thiab cov tshuaj tiv thaiv kev khov uas lwj lawm yuav xeb dua thiab muaj viscosity ntau dua. Yog li ntawd, nws raug pom zoo kom hloov cov tshuaj tiv thaiv kev khov tsis tu ncua thiab qhov kev pom zoo hloov zaus yuav yog ib xyoos ib zaug. Thaum lub caij ntuj sov, peb siv dej huv. Thaum lub caij ntuj no, peb hloov cov tshuaj tiv thaiv kev khov tshiab.
3. Tsis txhob sib xyaw ntau hom tshuaj tiv thaiv kev khov
Nws raug pom zoo kom siv tib hom thiab tib hom tshuaj tiv thaiv kev khov. Qhov ntawd yog vim tias txawm tias ntau hom tshuaj tiv thaiv kev khov muaj cov khoom xyaw zoo ib yam, lawv cov khoom ntxiv yuav txawv. Kev sib xyaw ntawm ntau hom tshuaj tiv thaiv kev khov yuav ua rau muaj kev tsis haum tshuaj, ua rau muaj npuas lossis kev sib xyaw.
