Dab tsi yog qhov zoo ntawm cenospheres hauv kev lag luam txheej?

Cenospheresyog ib yam khoom muab rho tawm los ntawmya tshauv . Nws muaj ntau yam khoom xws li qhov loj me me, qhov loj ntawm qhov chaw, thiab cov hluav taws xob zoo heev. Nws yog dav siv nyob rau hauv ntau yam teb. Dab tsi yog qhov zoo ntawm daim ntawv thov hauv kev lag luam txheej?

A- Qhov zoo ntawm cenospheres hauv kev lag luam txheej

1. Tus nqi ntawm cov resin yog me me. Vim hais tias ntawm qhov me me ntawm thaj tsam ntawm ib lub kheej kheej hauv ib qho duab, cov hlaws yuav tsum muaj cov resin tsawg dua. Particle packing kuj zoo dua. Qhov dav particle loj faib ntawm cenospheres ua rau me me microspheres sau cov voids ntawm cov microspheres loj.

2. Txhim khu kev ua kua. Tsis zoo li cov khoom tsis sib xws, cenospheres yob yooj yim ntawm ib leeg, txhim kho fluidity. Qhov no ua rau qis dua viscosity thiab zoo ntws zog rau cov tshuab siv cenospheres. Tsis tas li ntawd, sprayability yog txhim kho.
ua
3. High hardness thiab lub zog.Cenospheresyog cov muaj zog, tawv microspheres uas txhim khu lub hardness, txhuam tsis kam thiab abrasion tsis kam ntawm coatings.
ua
4. Zoo thermal rwb thaiv tsev nyhuv. Vim lub hollow spherical qauv ntawm cenospheres, nws muaj zoo thermal rwb thaiv tsev nyhuv thaum sau nyob rau hauv coatings.
ua
5. tuaj yeem tswj tau qhov gloss. Raws li ib tug muab tub lim, cenospheres tuaj yeem txo gloss, thiab txawm tias nyob rau hauv cov ntaub ntawv ntawm cov kev xav tau ntau ntxiv, lawv tuaj yeem tshem tawm qhov nce ntxiv hauv cov viscosity uas cov neeg sawv cev matting feem ntau ua rau, thiab lawv kuj raug nqi qis.
ua
6. Cov khoom xyaw tshwj xeeb inert. Cenospheres yog tsim los ntawm cov khoom xyaw inert, ua rau muaj kev ua haujlwm zoo heev, huab cua tsis kam, tiv thaiv corrosion thiab tshuaj lom neeg.
ua
7. Ntxiv kev pab them nqi. Cenospheres yog hollow spheres uas qeeb thiab tawg lub teeb thiab yog opaque, uas nyob rau hauv lem tsub kom lub zais zog ntawm cov xim.
ua
8. Kev tawg. Cenospheres yog dispersed zoo li cov pob zeb hauv av. Vim lawv cov phab ntsa tuab thiab siab compressive zog, cenospheres tuaj yeem tiv taus kev ua haujlwm ntawm txhua hom mixers, extruders thiab molding tshuab.
ua
9. Tsis muaj crystalline silicon muaj kuab paug. Tsis zoo li lwm cov fillers, cov ntsiab lus ntawm crystalline silicon nyob rau hauv cenospheres yog qis dua qib uas tsis muaj kev phom sij. Cenospheres tsis suav hais tias muaj kev phom sij thiab tsis tas yuav muaj cov cim ceeb toom tshwj xeeb.

Qhov thib ob, cov khoom tseem ceeb txheej siv los ntawm cenospheres
ua
B. Thermal rwb thaiv tsev txheej
ua
Txij li thaum qhov kub tsis kam ntawm cenospheres yog siab li 1500 degrees thiab thermal conductivity yog me me, nws tuaj yeem muab ntxiv rau cov txheej txheej ua cov khoom siv thermal rwb thaiv tsev, uas tuaj yeem ua rau cov thermal rwb thaiv tsev zoo ntawm txheej. Siv cenospheres ua cov khoom siv tseem ceeb, cov ntsiab lus tsis tshua muaj siab kub-resistant thermal rwb thaiv tsev tshuaj tsuag txheej yog npaj, uas muaj cov yam ntxwv ntawm lub teeb yuag thiab tswj tau shrinkage tom qab hlawv. Qee cov kws tshawb nrhiav pom tias qhov sib ntxiv ntawm cenospheres rau txheej txheej tau txhim kho cov thermal rwb thaiv tsev ntawm txheej. Thaum cov koob tshuaj yog 9%, cov nyhuv thermal rwb thaiv tsev yog qhov zoo tagnrho.

2. nplaim retardanthluav taws kub retardanttxheej
ua
Cenospheres muaj kub refractory siab thiab muaj cov yam ntxwv ntawm tsis-combustibility, tsis-deformation thiab pa luam yeeb-dawb nyob rau hauv siab kub. Lawv yog cov hluav taws-resistant thiab nplaim-retardant inorganic non-metallic cov ntaub ntawv thiab yog zoo muab tub lim rau zus tau tej cov hluav taws-retardant thiab nplaim-retardant txheej. Ntxiv txog 60 qhov chaw ntawm cov xim sib xyaw nrog ntau tshaj 10 yam khoom siv raw, cov khoom muaj adhesion zoo heev, cov nplaim hluav taws xob zoo thiab cov nyhuv suab nrov zoo kawg nkaus, thiab muaj qhov ua tau zoo heev thiab kub tsis kam.
ua
3. Muaj anti-corrosion txheej
ua
Cenospheres kuj tau ua tiav cov txiaj ntsig zoo hauv kev tiv thaiv corrosion thiab tiv thaiv xeb. Nws tuaj yeem ntxiv 6 ~ 10 cov ntsiab lus ntawm cenospheres los npaj cov qauv hlau uas tsis muaj kev nthuav dav los tiv thaiv corrosion txheej, uas yog siv los tiv thaiv corrosion ntawm steel qauv hauv kev tsim kho ntawm qhov project. Cov txheej muaj qhov zoo corrosion kuj thiab kub tsis kam, thiab siv rau hauv cov khoom siv tshuaj. Tsis yooj yim rau poob, lub neej ua haujlwm ntev

4. Waterproof txheej
ua
Cov dej nqus dej ntawm cov cenospheres yog tsawg, li 5%, thiab cov tee dej yog cov dej lwg zoo li ntawm cov cenospheres, qhia tau hais tias cov cenospheres muaj cov dej tsis zoo thiab tuaj yeem siv los ua cov khoom siv dej tsis zoo. Lub polymer cement-based waterproof txheej yog tsim los ntawm kev siv cov hlaws ntab ntab thiab montmorillonite, ntxiv cenospheres, txhim kho cov dej ntws ntawm cov cement slurry thiab txo cov nqi tsim khoom. 15% cenospheres tau ntxiv rau hauv kev tsim khoom, thiab cov khoom lag luam muaj cov dej tsis zoo.
ua
5. Lwm cov txheej txheem
ua
Siv cenospheres ua muab tub lim, ntxiv rau cov txheej txheem saum toj no, cov hmoov qhuav ua rau cov thermal rwb thaiv tsev txheej nrog cov thermal conductivity tsawg, muaj kev cuam tshuam siab, hnav tsis kam, nplaim hluav taws kub thiab huab cua tsis kam kuj tuaj yeem tsim. Nws muaj anti-corrosion thiab acid thiab alkali tsis kam. Thaum cov txheej txheej nyias nyias, nws yog flammable thiab muaj kev ua haujlwm zoo los tiv thaiv xob laim.
