Qhov sib txawv tseem ceeb ntawm perlite thiab zeolite yog tias perlite tshwm hauv xim dawb thaum zeolite tshwm hauv xim daj, xiav, lossis ntsuab xim.
Perlite yog ib qho inorganic compound uas muaj cov ntsiab lus dej siab, thiab nws yog hom amorphous volcanic iav. Zeolite, ntawm qhov tod tes, yog microporous aluminosilicate ntxhia.
YPerlite yog dab tsi?
Perlite yog ib qho inorganic compound uas muaj cov ntsiab lus dej siab thiab yog hom amorphous volcanic iav. Cov ntxhia no feem ntau tsim los ntawm hydration ntawm obsidian thiab ib txwm tshwm sim hauv ib puag ncig. Nws muaj cov cuab yeej txawv txav uas nthuav dav heev thaum cua sov rau qhov kub txaus.
Feem ntau, cov ntxhia pob zeb perlite nyiam mos nws tus kheej thaum cua sov rau qhov kub ntawm li 850 txog 900 degrees Celsius. Nyob ntawd, cov dej molecules uas tau daig hauv nws cov qauv zoo li vaporize thiab khiav tawm ntawm cov pob zeb hauv av, ua rau cov khoom nthuav dav nws tus kheej mus txog 7 mus rau 16 npaug ntawm nws qhov qub ntim. Cov khoom siv nthuav dav no tshwm hauv cov xim dawb ci ntsa iab. Qhov no yog vim qhov cuam tshuam ntawm cov npuas npuas. Thaum xav txog qhov ceev ntawm perlite, daim ntawv tsis nthuav dav muaj qhov ntom ntom ntawm li 1100 kg / m3 thiab daim ntawv nthuav dav muaj qhov ceev ntawm li 30 - 150 kg / m3.
Daim duab 01: Nthuav Perlite Mineral
Peb tuaj yeem pom tias perlite yog qhov tsis tuaj yeem txuas ntxiv hauv ntiaj teb. Tsuas muaj li ntawm 700 lab tonnes ntawm perlite hauv ntiaj teb raws li kev kwv yees. Feem ntau cov reserves yog nyob rau hauv Armenia, Greece, Qaib ntxhw, lub teb chaws USA, thiab Hungary.
Muaj ntau ntau yam kev siv thiab kev siv ntawm perlite, uas suav nrog kev tsim kho thiab tsim cov plasters, pob zeb, mortar, rwb thaiv tsev thiab qab nthab vuas, tsim cov ntaub ntawv sib xyaw, tsim ua npuas ncauj, thiab lwm yam.
YZeolite yog dab tsi?
Zeolite yog microporous aluminosilicate ntxhia. Nws yog tsuas yog pab tau raws li ib tug catalyst. Nyob rau hauv kev lag luam nplai, nws muaj txiaj ntsig zoo li adsorbent. Lub sij hawm no tau los rau hauv koob meej hauv 1756 tom qab kev tshawb fawb ntawm Swedish mineralogist Axel Fredrik Cronstedt. Nws tau soj ntsuam kev tsim cov pa ntau ntawm cov dej (uas tshwm sim hauv cov khoom siv los ntawm adsorption) thaum cua kub ceev ntawm ib qho khoom uas muaj stilbite. Raws li qhov kev soj ntsuam no, tus kws tshawb fawb no hu ua cov khoom siv zeolite, uas muaj lub ntsiab lus Greek, "zeo"="to boil", thiab "lithos"="stone".
Daim duab 02: Microporous Structure ntawm Zeolite
Nws muaj cov qauv ntxeem tau hauv zeolite, uas tuaj yeem cuam tshuam nrog ntau yam cations, suav nrog Na+, K+, Ca2+ thiab Mg2+. Cov no yog cov ions zoo uas tuaj yeem tuav tau xoob. Yog li, cov ions no tuaj yeem hloov pauv rau lwm cov ions thaum sib cuag nrog kev daws teeb meem. Cov tswv cuab hauv pob zeb hauv pawg zeolite suav nrog analcime, chabazite, clinoptilolite, stilbite, thiab lwm yam.
Thaum xav txog cov khoom ntawm zeolite, cov ntaub ntawv tshwm sim tuaj yeem ua rau cov dej hauv av alkaline. Tsis tas li ntawd, cov ntaub ntawv no tuaj yeem tau crystallized nyob rau hauv ib puag ncig tom qab depositional ntau lub sijhawm. Tsis tas li ntawd, cov qauv zeolite tsis tshua muaj tshwm sim hauv lub xeev ntshiab. Lawv feem ntau kis nrog lwm yam minerals, hlau, quartz, thiab lwm yam.
Qhov txawv ntawm Perlite thiab Zeolite yog dab tsi?
Perlite thiab zeolite yog cov khoom ntxhia uas tshwm sim ib txwm muaj. Perlite yog ib qho inorganic compound uas muaj cov ntsiab lus dej siab, thiab nws yog amorphous volcanic iav hom. Zeolite yog microporous aluminosilicate ntxhia. Qhov sib txawv tseem ceeb ntawm perlite thiab zeolite yog tias perlite tshwm hauv xim dawb thaum zeolite tshwm hauv xim daj, xiav, lossis ntsuab xim. Ntxiv mus, thaum perlite muaj cov qauv iav amorphous, zeolite muaj cov qauv microporous.
Cov infographic hauv qab no teev qhov sib txawv ntawm perlite thiab zeolite hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Perlite vs Zeolite
Perlite thiab zeolite yog cov khoom ntxhia uas tshwm sim ib txwm muaj. Qhov sib txawv tseem ceeb ntawm perlite thiab zeolite yog tias perlite tshwm xim dawb thaum zeolite tshwm hauv xim daj, xiav, lossis ntsuab xim.
