Kev txhais siab ntxiv Perlite rau hauv cov txaj tsa - muag kub perlite lossis kev ua liaj ua teb perlite lossis nthuav dav perlite siv hauv vaj - Kehui

Perlite nthuav dav yog ib hom khoom siv dawb granular nrog cov qauv honeycomb sab hauv uas yog ua los ntawm perlite ore tom qab preheating thiab tam sim ntawd kub siab roasting thiab nthuav dav. Lub hauv paus ntsiab lus yog: perlite ore yog crushed los ua ore xuab zeb ntawm ib qho me me, uas yog preheated thiab roasted thiab cua sov sai (saum toj no 1000 ℃). Cov dej hauv ore yog vaporized thiab nthuav dav hauv cov mos mos vitreous ore los ua cov khoom tsis yog hlau nrog cov qauv porous thiab qhov ntim nthuav dav ntawm 10-30 zaug. Perlite yog muab faib ua peb daim ntawv raws li nws cov thev naus laus zis nthuav dav thiab siv: qhib pores, kaw pores, thiab hollow pores.

Qhov Loj ntawm Cov Khoom Me Me

1-3 hli, 3-6 hli, 4-8 hli.

Scope ntawm daim ntawv thov

Perlite nthuav dav yog cov khoom siv inorganic uas muaj ntau yam kev siv. Raws li nws cov thev naus laus zis nthuav dav thiab kev siv, nws muab faib ua peb hom: qhib qhov, kaw qhov, thiab khoob qhov. Cov khoom lag luam cuam tshuam yuav luag txhua qhov chaw. Piv txwv li:

1-Lub tshuab ua pa oxygen, cia khoom txias, kua oxygen thiab kua nitrogen thauj mus los ua cov khoom siv rwb thaiv tsev thermal.

2- Siv rau kev lim dej cawv, roj, tshuaj, khoom noj, dej phwj thiab lwm yam khoom.

3- Rau roj hmab, xim, txheej, yas, thiab lwm yam khoom sau thiab nthuav dav.

4- Rau cov neeg uas muaj kev xav tau tshwj xeeb.

5- Siv los nqus cov roj slicks.

6-Siv rau hauv kev ua liaj ua teb, kev ua teb, kev txhim kho av, kev txuag dej thiab chiv, kev cog qoob loo tsis muaj av, kev txhim kho av, tshuaj tua kab qeeb qeeb, thiab lwm yam.

7- Nws yog siv los koom tes nrog ntau yam nplaum los ua cov profiles ntawm ntau yam specifications thiab cov khoom.

8- Siv ntau dua rau kev rwb thaiv tsev ntawm cov qhov cub hluav taws thiab cov ru tsev thiab phab ntsa. Kev tsim kho: rwb thaiv tsev, cov tshuaj tiv thaiv hluav taws, cov vaj huam sib luag uas nqus suab thiab lwm yam rwb thaiv tsev, rwb thaiv tsev txias thiab cua sov, cov ntaub ntawv lim dej, cov ntaub ntawv sau slag hauv cov txheej txheem ua hlau, roj hmab thiab yas sau cov ntaub ntawv, thiab lwm yam.
