Kusintha kwa calcium carbonate

Kusintha kwa calcium carbonate

Heavy calcium carbonate imatha kuonjezera kuchuluka kwa zinthu zapulasitiki, kuchepetsa ndalama, kulimbitsa kuuma ndi kuuma, kuchepetsa kuchepa kwa zinthu zapulasitiki, ndikuwongolera kukhazikika;kusintha ntchito processing wa mapulasitiki, kusintha kutentha kukana, kusintha astigmatism mapulasitiki, odana- Pa nthawi yomweyo, izo ndi zotsatira zoonekeratu pa toughening zotsatira za notched mphamvu mphamvu ndi viscous otaya pa ndondomeko kusanganikirana.

Zimango katundu

Calcium carbonate yakhala ikugwiritsidwa ntchito ngati inorganic filler mu kudzaza pulasitiki kwa zaka zambiri.M'mbuyomu, calcium carbonate inkagwiritsidwa ntchito ngati chodzaza ndi cholinga chachikulu chochepetsera ndalama, ndipo idalandira zotsatira zabwino.M'zaka zaposachedwa, pogwiritsa ntchito kwambiri kupanga komanso kafukufuku wambiri, ndizothekanso kudzaza calcium carbonate yambiri popanda kuchepetsa kwambiri kupanga.

Pambuyo podzaza ndi calcium carbonate, chifukwa cha kuuma kwakukulu kwa calcium carbonate, kuuma ndi kuuma kwa mankhwala apulasitiki kudzakhala bwino, ndipo mphamvu zamakina zidzakulitsidwa.Kulimba kwamphamvu komanso kusinthasintha kwazinthuzo kwasinthidwa, ndipo zotanuka modulus yazinthu zapulasitiki zasinthidwa kwambiri.Poyerekeza ndi FRP, mphamvu zake zolimba, mphamvu zosunthika ndi zosinthika modulus ndizofanana ndi za FRP, ndipo kutentha kwa kutentha kumakhala Koposa FRP, chinthu chokhacho chotsika kwa FRP ndi mphamvu yake yotsika, koma kuipa kumeneku kungathe. gonjetsani powonjezera ulusi wochepa wa galasi.

Kwa mapaipi, kudzaza kashiamu carbonate kumatha kusintha zizindikiro zake zingapo, monga kulimba kwamphamvu, kulimba kwa mpira wachitsulo, kulimba kwamphamvu, kutsika kwa viscous, kukana kutentha, ndi zina zambiri;koma nthawi yomweyo idzachepetsa zizindikiro zake zingapo zolimba, monga elongation pa nthawi yopuma, kusweka mofulumira, mphamvu yamphamvu ya matabwa omwe amathandizidwa, ndi zina zotero.

Kutentha kwachangu

Pambuyo powonjezera zodzaza, chifukwa cha kukhazikika kwabwino kwa matenthedwe a calcium carbonate, kuchuluka kwa matenthedwe kowonjezera ndi kutsika kwazinthuzo kumatha kuchepetsedwa chimodzimodzi, mosiyana ndi magalasi opangidwa ndi magalasi opangidwa ndi thermoplastics, omwe ali ndi mitengo yocheperako yosiyana m'magawo osiyanasiyana.Pambuyo pake, tsamba lankhondo ndi kupindika kwa mankhwalawa kumatha kuchepetsedwa, chomwe ndi chinthu chachikulu kwambiri poyerekeza ndi fiber filler, ndipo kutentha kwamafuta kumawonjezeka ndi kuchuluka kwa zodzaza.

radioactivity

Chodzazacho chimatha kuyamwa cheza, ndipo nthawi zambiri chimatha kuyamwa 30% mpaka 80% ya cheza cha ultraviolet kuteteza kukalamba kwa zinthu zapulasitiki.
