Yuav ua li cas nkag siab txog cov iav particle loj kuaj
Mar 21, 2026
Yog tias koj tau ua haujlwm hauv iav tsim, koj paub tias txhua yam pib nrog cov khoom siv. Thiab ib qho ntawm cov kev kuaj xyuas zoo tshaj plaws yog qhov ntsuas particle loj.
Kuv tau pom ntau qhov tsis xws luag rov qab mus rau qhov tsis sib xws ntawm cov khoom siv raw khoom ntau dua li yuav luag txhua yam. Cia kuv rhuav tshem qhov koj yuav tsum paub tiag tiag.
1. Ob qhov kev xeem sib txawv, tsis txhob sib xyaw ua ke
Thaum tib neeg hais tias "iav particle loj kuaj," lawv feem ntau tham txog ib qho ntawm ob yam:
Raw khoom particle loj - cov xuab zeb, dej qab zib tshauv, thiab limestone mus rau hauv lub cub tawg. Yog tias cov no tsis sib xws, koj cov yaj yuav tsis zoo ib yam.
Tempered iav fragmentation - tawg tempered iav ntawm lub hom phiaj kom pom tias nws tawg mus rau hauv cov pob zeb me me -zoo li daim (yuav tsum muaj kev nyab xeeb).
Ob qhov kev xeem sib txawv kiag li. Paub qhov twg koj tab tom cuam tshuam.
2. Raw Khoom: Sieve Test
Rau cov khoom siv raw, mus- rau tus qauv hauv Asmeskas yog ASTM C429.
Nws ua haujlwm li cas: nqa ib qho qauv, khiav nws los ntawm ib pawg ntawm sieves, co nws, thiab ntsuas qhov seem ntawm txhua tus. Uas muab koj particle loj faib.
Qhov tseem ceeb:
Coarse → unmelted nplej nyob rau hauv lub khob kawg
Zoo heev → hmoov av nyob txhua qhov chaw, tsis sib haum xeeb
Yooj yim li ntawd.
3. Tempered iav: Kev Xeem Fragmentation
Rau cov iav tempered, cov lus nug yog: nws puas tawg zoo?
Raws li ASTM C1048 lossis EN 12150, koj ntaus lub khob nrog rauj me me (kwv yees li 75g) thiab suav cov seem hauv 50mm x 50mm square.
Txoj cai: tag nrho tempered iav xav tau yam tsawg kawg 40 fragments nyob rau hauv cheeb tsam ntawd. Tsawg dua qhov txhais tau tias nws tsis zoo tempered.
Yog tias koj tab tom cuam tshuam nrog kev nyab xeeb glazing, qhov kev sim no tseem ceeb.
4. Laser Diffraction: Txoj Kev Niaj Hnub No
Sieve tsom xam ua haujlwm thiab nws pheej yig. Tab sis rau super- cov hmoov zoo lossis tau txais txiaj ntsig sai dua, cov chaw sim siv laser diffraction.
Tua ib lub laser los ntawm cov qauv, ntsuas seb lub teeb tawg li cas, thiab lub khoos phis tawj tawm mus rau tag nrho cov particle loj faib hauv feeb. Cov cuab yeej zoo li FRITSCH ANALYSETTE 22 NeXT tuaj yeem ntsuas los ntawm 0.01 microns txog 3800 microns.
Upside: ceev thiab automated. Downside: nqi ntau tshaj ib pawg ntawm sieves.
5. Yuav nug cov neeg muab khoom li cas
Yog tias qhov loj me me tseem ceeb rau koj daim ntawv thov, ntawm no yog qhov kuv xav nug:
"Koj siv tus qauv dab tsi?" ASTM C429 Cov Lus Qhia JC/T 650? Yog lawv tsis tuaj yeem qhia koj, tus chij liab.
"Kuv puas tuaj yeem pom cov ntaub ntawv faib tawm?" Ib feem pua dua dhau tsis qhia koj ntau. Qhov nkhaus qhia koj txhua yam.
