2021 Zoo Microspheres Cenosphere - Reflective Iav hlaws dai rau Txoj Kev Cim - Kehui

Cov hlaws iav yog ib yam khoom tshiab uas tau tsim nyob rau xyoo tas los no nrog ntau yam kev siv thiab cov khoom tshwj xeeb. Cov khoom no yog ua los ntawm cov khoom siv borosilicate raw los ntawm kev ua cov txheej txheem siab, nrog rau qhov loj me ntawm 10-250 microns thiab phab ntsa tuab ntawm 1-2 microns. Cov khoom muaj qhov zoo ntawm qhov hnyav sib dua, kev ua kom sov tsawg, lub zog siab, kev ruaj khov tshuaj zoo, thiab lwm yam. Nws qhov chaw tau kho tshwj xeeb kom muaj cov khoom lipophilic thiab hydrophobic, thiab nws yooj yim heev rau kev tawg hauv cov khoom siv organic.
Cov iav me me siv rau hauv kev tshem tawm xeb ntawm cov tshuab aerospace, kev hla zebra, cov kab tsis nres, ob kab daj thaum hmo ntuj reflections ntawm txoj kev hauv nroog, thiab cov khoom siv reflection hmo ntuj rau cov paib tsheb.

Cov khoom xyaw ntsuas
1. Cov tshuaj lom neeg muaj pes tsawg leeg:
SiO2 > 67%, CaO > 8.0% MgO > 2.5%, Na2O 0.15, lwm yam 2.0%.
2. Qhov hnyav tshwj xeeb: 2.4-2.6g / cm³.
Tsos: du, puag ncig, pob tshab iav tsis muaj impurities
Tus nqi sib npaug: ≥85% lossis ntau dua.
3. Cov khoom sib nqus yuav tsum tsis pub tshaj 0.1% ntawm qhov hnyav ntawm cov khoom.
4. Cov ntsiab lus npuas hauv cov hlaws iav yog tsawg dua 10%.
5. Tsis muaj cov khoom xyaw silicone resin.
6. Qhov ceev ntawm cov khoom: 1.5g / cm³
7. Mohs hardness: 6-7
8. Rockwell hardness: 48-52HRC

Cov hlaws iav muaj ntau yam kev siv thiab cov khoom tshwj xeeb. Lawv muaj lub cheeb me me, lub teeb yuag thiab lub zog siab. Ntxiv lawv rau hauv cov txheej txheej tuaj yeem ua rau lawv ua cov txheej txheej uas tib neeg xav tau. Kev ua tau zoo retro-reflection, rau qhov loj, lub teeb tuaj yeem ncaj qha rov qab mus rau qhov chaw teeb, yog li nws tsim cov nyhuv retro-reflection muaj zog. Kev siv cov hlaws iav reflection tau txhim kho kev nyab xeeb ntawm txoj kev zoo heev.

Cov xim uas ntxiv nrog cov hlaws iav ci ntsa iab ntawm txoj kev tsis tas yuav muaj hluav taws xob, thiab kuj tseem tuaj yeem ua tiav cov haujlwm ceeb toom ntawm cov cim qhia hmo ntuj. Yog li ntawd, cov hlaws iav ci ntsa iab ntawm txoj kev siv rau hauv cov cim qhia kev tsheb, cov chaw sab nraum zoov, cov cim qhia kev thiab lwm yam kev ceeb toom thaum hmo ntuj. Tag nrho cov cim tau txhim kho kev lees paub cov cim no thaum hmo ntuj, ua lub luag haujlwm zoo heev hauv kev coj thiab ceeb toom, thiab muab txoj kab kev nyab xeeb zoo dua rau cov neeg tsav tsheb uas tsav tsheb thaum hmo ntuj.

Qhov zoo ntawm txoj kev iav hlaws dai:

Cov khoom siv iav microbead uas ci ntsa iab raug ntxiv ncaj qha rau hauv lub tshuaj ntsiav uas muaj dej, thiab tom qab ntawd kho kom sib npaug. Yog tias tsim nyog, tuaj yeem ntxiv qee yam khoom ntxiv kom txhim kho nws qhov ruaj khov, thiab tom qab ntawd nws tuaj yeem siv ncaj qha. Ntxiv nws ncaj qha rau hauv cov slurry pob tshab, do kom sib npaug, thiab ntxiv qee yam khoom ntxiv raws li qhov xav tau tiag tiag kom ua rau nws tau txais txiaj ntsig zoo dua.

Cov iav microbeads uas cuam tshuam txoj kev tuaj yeem ntxiv ncaj qha rau hauv cov kua mem kom ua cov kua mem ci, uas tuaj yeem luam tawm lossis pleev xim rau ntawm cov ntaub lossis lwm yam khoom. Nws yooj yim heev thiab yooj yim siv thiab yooj yim rau kev tswj hwm. Nws yuav tsum tau sau tseg tias cov iav microspheres uas cuam tshuam qhov ntau ntawm cov hlaws dai ntxiv tuaj yeem ntxiv raws li qib kev cuam tshuam xav tau.

Ua ntej, tsuag lub hauv paus ci ntsa iab, thiab tom qab ntawd tos kom txog thaum lub hauv paus ci ntsa iab qhuav ua ntej tsuag cov xim pleev xim ci ntsa iab. Yog tias qhov chaw cement tau tsim, nws yuav zoo dua los tsuag ob txheej ntau zaus. Thaum tsuag, nws raug pom zoo kom siv cov kws tshaj lij. Tib lub sijhawm, thaum tsuag, sim ua ntej thaj chaw me me, xyuam xim rau cov huab cua ntawm kev tsim kho, sim tsis txhob tsim kho thaum muaj nag, kom tsis txhob ua rau cov iav me me tsis tuaj yeem ua si tag nrho.
