Iimpawu zeCenospheres Hollow Microspheres

IiCenospheres (IziMathiriyeli zeMineral Ezandisiweyo ezineAlumina kunye neSilica) yimveliso ephuma kwimizi-mveliso yamandla okutshisa amalahle kwaye ilula, ingaphakathi, ingqukuva enomgongxo ezaliswe ngumoya okanye igesi engasebenziyo. umbala we-Cenosphere uyahluka ukusuka kungwevu ukuya phantse kumhlophe kwaye ukuxinana kwawo malunga ne-0.4 - 0.8 g / cm3 (0.014 - 0.029 lb./cu in), ebonelela nge-buoyancy.
Iicenospheres zisetyenziswa njengesizalisi esilula kwikhonkrithi kunye neeplastiki. Izangqa zixutywe neresin ukwenza amagwebu enziwe lula asetyenziswa njengemathiriyeli engundoqo yeepaneli zesandwich, iibhloko zezixhobo, kunye negwebu le-buoyancy. Zisetyenziselwa ukwenza iithayile ezichasene nobushushu kunye neengubo ze-ceramic ezine-conductivity ephantsi ye-thermal. I-Metal-coated cenospheres yongezwa kwiipeyinti ezikhuselayo ze-EMI.

Iimpawu zeCenospheres(ekwabizwa ngegamaIMikrosphere eHollow):

1. I-fluidity elungileyo: I-microbeads engenanto i-microspheres ejikelezayo evulekileyo kunye ne-particle diameter ye-0.2µm-400µm, kunye nesantya se-spherical yi-≥95%, eyandisa ukumanzi kwezinto ezizaliswe kwaye yenza ukuba izinto ezizalisweyo zilungele ukulungiswa.
2. Ubuninzi obuphantsi: ii-microspheres ezingenanto zinemveliso ye-0. 4g / cm3 -0. 8g/cm3. Xa kuthelekiswa nezixhobo ezininzi zeminerali yomhlaba, i-microspheres engenanto i-30% -85% ilula ngobunzima.
3. Iqondo eliPhezulu lokuZaliswa: Imicrospheres eHollow ithatha indawo yomphezulu encinci ukuba izaliswe. Ngenxa yokwakheka kwayo, i-viscosity iyancipha kakhulu.
4. Amandla aphezulu: ii-microspheres ezingenanto ziyakwazi ukumelana ne-4000 kg / cm ngenxa yegobolondo eliqinileyo.
Amandla oxinzelelo ukusuka kwi-3 ukuya kwi-7000 kg / cm3.
5. I-Shrinkage ephantsi: Ubuhlalu be-Cavity yenye yezinto ezimbalwa kwintsimi yokuzalisa ezinokufikelela kwi-shrinkage ephantsi. Isantya sokucutheka kwenani elikhulu lee-microspheres ezingenanto ezigcweleyo.
6.Ukufakwa kobushushukunye nokugquma isandi: Indawo enomgongxo yenza ukuba i-microspheres evulekileyo ibe ne-conductivity ephantsi ye-thermal kwaye ingasetyenziselwa ukugquma ubushushu kunye nezixhobo zokugquma isandi.
7. Ukuzinza okuqinileyo: ii-microspheres ezingenanto zingongezwa kwi-solvents, iikhemikhali eziphilayo, amanzi, i-acids okanye iziseko ngaphandle kokutshintsha iikhemikhali zazo.
8. Ukumelana nokushisa okuphezulu: Ekubeni indawo yokunyibilika ye-microspheres engenanto iphezulu njenge-1450 ° C, inokuhlala izinzile kumaqondo aphezulu ngaphezu kwe-1000 ° C.
9. Ukugquma kombane: Sebenzisa izitshixo zombane ezahlukeneyo, iipaneli zesixhobo, kunye nezinto zokupakisha zombane ukuphucula ukugquma.
10. Ixabiso eliphantsi: Ixabiso le-microspheres engenanto yi-50% -200% ngaphantsi kwe-microspheres eyenziweyo.
