Mica Ua Ntawv Thov Xim thiab Txheej Kev Lag Luam

(1) Qhov Teeb Meem Siv

Hauv cov xim ua yeeb yaj kiab, flaky muab tub lim yuav tsim cov kev sib txig sib luag, yog li muaj kev tiv thaiv kev nkag mus ntawm cov dej thiab lwm yam tshuaj tiv thaiv, thiab yog tias siv cov mica zoo hmoov (lub taub-tuab piv tau tsawg kawg 50 zaug, nyiam 70 zaug), qhov no hom kev ncua sijhawm yuav nquag txuas ntxiv 3 zaug. Raws li mica muab tub lim yog ntau pheej yig dua li cov roj tshwj xeeb, nws muaj cov txuj ci siab heev thiab kev lag luam muaj txiaj ntsig.

Hauv kev luv luv, kev siv cov tshuaj mica zoo hmoov yog qhov tseem ceeb rau kev txhim kho kom zoo dua qub thiab ua haujlwm ntawm kev tiv thaiv kev txhim kho thiab kev tiv thaiv sab nrauv phab ntsa. Thaum lub sijhawm txheej txheem, ua ntej cov xim zaj duab xis yog ua kom muaj zog, mica chips yuav pw hauv qab qhov nro thiab tom qab ntawd cia li tsim cov kab sib txuas rau ib leeg thiab mus rau saum npoo ntawm cov xim zaj duab xis. Qhov kev qhia ntawm hom kev sib txuam no yog txoj cai txiav txim siab ntawm cov tshuaj tiv thaiv corrosive 'nkag mus rau cov xim zaj duab xis, yog li ua si nws txoj hauv kev cuam tshuam rau cov feem ntau. Qhov teeb meem yog tias cov qauv mica flaky yuav tsum yog zoo meej, raws li txawv teb chaws cov tuam txhab kev lag luam teeb tsa tus qauv uas qhov taub-thickness piv yuav tsum tsawg kawg 50 zaug, nyiam dua ntau dua 70 npaug, txwv tsis pub cov txiaj ntsig yuav tsis tsim nyog, vim tias daim nyias nyias yog, qhov loj dua qhov muaj qhov thaiv qhov loj dua nrog cov ntsuas qhov ntim ntawm qhov muab tub lim, ntawm qhov tsis sib xws, yog tias lub nti yog tuab heev, ces nws tsis tuaj yeem tsim ntau cov khaubncaws sab nraud povtseg. Yog vim li cas thiaj muab cov granule muab ntxaws tsis ua txoj haujlwm no. Tsis tas li, perforation thiab avulsion ntawm lub mica nti yuav cuam tshuam loj heev no lub luag haujlwm thaiv teeb meem (tshuaj tiv thaiv xau tuaj yeem yooj yim xau hauv). Qhov thinner lub mica nti yog, qhov loj dua qhov chaw teeb meem nrog chav tsev ntim ntawm qhov muab tub lim. Cov txiaj ntsig zoo dua yuav ua tiav nrog lub cev loj me me (nyias kuj tsis zoo ib txwm).

(2) Txhim Kho Cov Khoom Uas Lub Cev thiab Khoom Sib Txheeb ntawm Zaj Duab Xis

Kev siv ntub av mica hmoov av tuaj yeem txhim kho cov khoom siv lub cev thiab lub zog ntawm cov xim tha xim. Tus yuam sij yog cov yam ntxwv morphological ntawm cov muab tub lim, uas yog, lub taub-thickness piv ntawm flaky muab tub lim thiab ntev-txoj kab uas hla ntawm fibrous muab tub lim. Granular muab tub lim ua zoo li cov xuab zeb thiab pob zeb hauv cov pob zeb ua kom pob zeb txhawm rau txhim kho cov hlau.

(3) Txhim kho Cov Khoom Uas Los Tiv Thaiv Los Ntawm Zaj Duab Xis

Lub hardness ntawm resin nws tus kheej yog txwv, thiab kev siv ntawm ntau hom muab tub lim tsis siab (piv txwv li, talcum hmoov). Ntawm qhov tsis sib xws, mica, ib qho ntawm cov khoom siv ntawm granite, yog qhov zoo heev ntawm nws qhov nyuaj thiab lub zog lub zog. Yog li ntawd, ntxiv mica ua cov muab tub lim, los tiv thaiv kev hnav ua haujlwm ntawm cov tsho tiv thaiv tuaj yeem txhim kho zoo. Tias yog vim li cas mica hmoov yog dua li siv rau hauv cov xim pleev xim rau tsheb, txoj kev pleev xim, kev siv tshuaj tiv thaiv kev tiv thaiv kev txhim kho thiab txheej phab ntsa.

(4) Rwb thaiv tsev

Mica, nrog tus nqi hluav taws xob tsis tshua muaj siab (1012-15 ohm · cm), yog nyob rau hauv nws tus kheej cov khoom siv rwb thaiv tsev zoo tshaj plaws thiab nws yog qhov siv cov tshuab hluav taws xob los siv nws los txhim kho cov rwb thaiv tsev ntawm cov xim zaj duab xis. Dab tsi txaus siab yog tias thaum ua haujlwm nrog cov khoom siv sib xyaw ntawm cov organic silicon resin thiab organic silicon thiab boric resin, lawv yuav hloov mus rau ib hom ntawm cov khoom siv ceramic nrog cov zoo lub zog thiab insulating cov cuab yeej ib zaug ntsib qhov kub. Yog li no, xaim xov thiab xaim ua los ntawm cov hom insulating no tseem tuaj yeem tuav nws cov thawj cov khoom siv rwb thaiv tsev txawm tias tom qab hluav taws, uas yog qhov tseem ceeb heev rau cov av mines, tunnels, cov tsev tshwj xeeb thiab chaw, thiab lwm yam.

(5) Anti-Flaming

Mica hmoov yog ib hom muaj txiaj ntsig zoo heev rau hluav taws kub thiab nws tuaj yeem siv los ua cov nplaim hluavtaws thiab cov nplaim hluavtaws xim yog tias siv nrog cov organic halogen nplaim hluav taws.

(6) Anti-UV thiab Infrared Rays

Mica ua tau zoo heev hauv kev tiv thaiv kev tiv thaiv ultraviolet thiab duab ci ci, thiab lwm yam Yog li ntxiv cov av ntub mica hmoov rau hauv cov xim pleev xim sab nraud tuaj yeem txhim kho zaj duab xis los tiv thaiv ultraviolet kev ua haujlwm thiab qeeb nws kev laus. Los ntawm nws cov kev ua tau zoo ntawm kev tiv thaiv kev ua duab ci, mica yog siv hauv kev ua kom muaj cua sov thiab cov khoom siv tiv thaiv cua sov (xws li cov xim pleev xim).

(7) Txo Ntxo

Ncua kev kawm ntawm cov av ntub mica zoo heev. Cov tawv nyias thiab pob me me tuaj yeem muab ncua cia hauv qhov nruab nrab yam uas tsis muaj kev lim hiam. Yog li no, thaum siv mica hmoov ua cov muab tub lim hloov chaw uas yuav yooj yim zuj zus, qhov ruaj ntseg ntawm txheej cia yuav nce siab.

(8) Kev Ris Tshav Kub thiab Kev Tshav Kub Kub

Mica muaj lub peev xwm zoo ntawm radiating infrared rays. Piv txwv li, thaum ua haujlwm nrog hlau oxide, thiab lwm yam, nws tuaj yeem tsim cov teebmeem hluav taws xob thermal zoo heev. Cov qauv ua piv txwv feem ntau yog nws daim ntawv thov hauv cov chaw ua npuas av tiv thaiv (txo qhov kub ntawm lub hnub ci sab los ntawm kaum tawm degrees). Ntau cov xim pleev xim rau cov cua sov thiab cov chaw ua haujlwm siab-txhua qhov yuav tsum tau siv cov xim tshwj xeeb uas muaj cov tshuaj mica, vim tias cov tshuaj pleev xim tseem tuaj yeem ua haujlwm nyob hauv qhov kub txias heev, xws li 1000 ℃ lossis zoo li ntawd. Thaum lub sijhawm ntawd cov hlau yuav ua liab-kub, tab sis cov xim muaj hlau tseem tsis raug mob.

(9) Cov Ntsiab Lus Gloss

Mica muaj zoo pearlescent gloss, yog li, thaum siv loj-loj thiab daim nyias-daim ntawv mica khoom, cov khoom siv, xws li cov xim pleev xim thiab xim pleev xim, tuaj yeem ua kom zoo nkauj, ci lossis ua kom pom tseeb. Ntawm qhov tsis sib xws, super-nplua mica hmoov tuaj yeem ua kom rov ua tau thiab rov qab ua kom pom sab hauv cov ntaub ntawv, yog li tsim cov nyhuv delustering.

(10) Suab thiab Kev co Damping Teeb Meem

Mica tuaj yeem hloov pauv ntau yam ntawm lub cev qauv ntawm cov khoom siv nrog rau daim ntawv lossis hloov nws cov viscoelasticity. Cov ntaub ntawv zoo li no muaj peev xwm nqus tau lub zog kev co thiab ua rau lub zog poob siab thiab suab. Ntxiv mus, kev poob siab thiab cov suab nrov yuav tsim rov qab ua kom pom tseeb ntawm mica chips, uas tseem ua rau lub zog tsis muaj zog. Yog li no, ntub dej mica hauv av kuj tseem siv los npaj cov khoom kom nrov thiab kev co.
