Kuteteza Kutentha kwa Microsphere ya China - Kutentha kwa Madzi Ochepa Kutengera Magalasi Opanda Madzi - Kehui

Magalasi ang'onoang'ono opanda kanthu ali ndi kulemera kopepuka, voliyumu yayikulu, kutentha kochepa, mphamvu yopondereza kwambiri, komanso kusinthasintha kwabwino. Amagwiritsidwa ntchito ngati zodzaza zinthu ndi zowunikira m'zophimba utoto, rabala, mapulasitiki osinthidwa, mapulasitiki olimbikitsidwa ndi ulusi wagalasi, miyala yopangira, putty ndi mafakitale ena; M'mafakitale amafuta ndi gasi, magwiridwe antchito a kukana kwawo kupondereza kwambiri komanso kupsinjika kochepa amatha kupanga slurry ya simenti yotsika kwambiri komanso madzi obowola otsika.
Ma microspheres agalasi opanda kanthu ndi ma galasi opanda kanthu okhala ndi kukula kochepa, komwe ndi zinthu zopanda chitsulo. Kukula kwa tinthu tating'onoting'ono ndi ma microns 28-120, ndipo kuchuluka kwake ndi 0.2-0.6 g/cm3. Ili ndi ubwino wolemera pang'ono, kutentha kochepa, kutchinjiriza mawu, kufalikira kwakukulu, kutchinjiriza magetsi bwino komanso kukhazikika kwa kutentha. Ndi chinthu chatsopano chopangidwa chopepuka chomwe chimagwiritsidwa ntchito mosiyanasiyana komanso magwiridwe antchito abwino kwambiri.
1: Mtundu wa mawonekedwe ake ndi woyera. Ungagwiritsidwe ntchito kwambiri pazinthu zilizonse zomwe zili ndi zofunikira pa mawonekedwe ndi mtundu.
2: Mphamvu yokoka yopepuka komanso kuchuluka kwakukulu. Kuchuluka kwa ma microspheres opanda kanthu agalasi ndi pafupifupi gawo limodzi mwa magawo khumi a kuchuluka kwa tinthu tachikhalidwe todzaza. Pambuyo podzaza, imatha kuchepetsa kwambiri kulemera kwa chinthucho, kusintha ndikusunga ma resin ambiri opangira, ndikuchepetsa ndalama zomwe zimagwiritsidwa ntchito.
3: Ili ndi malo osinthika mwachilengedwe (ofanana ndi lipophilic). Ma microspheres agalasi opanda kanthu ndi osavuta kunyowetsa ndi kufalitsa, ndipo amatha kudzazidwa mu ma resins ambiri a thermosetting thermoplastic, monga polyester, pp, pvc, epoxy, polyurethane, ndi zina zotero.

Magalasi ozungulira opanda kanthu amaperekedwanso ndi zokutira zoyendetsera. Zophimba zoyendetsera zowongolera zokhala ndi makulidwe abwino zimapatsa tinthu tozungulira mphamvu zabwino zoyendetsera ndi kuteteza pamene zikusunga phindu losunga kulemera logwirizana ndi zipangizo zozungulira zopanda mphamvu zambiri. Magalasi ozungulira awa ndi oyenera kugwiritsidwa ntchito m'magulu ankhondo, sayansi ya zamoyo, zipangizo zachipatala, zamagetsi, ndi mafakitale ena apadera.

Tsatanetsatane:
Mtundu: woyera
Chinyezi: ≤ 0.5%
Chiŵerengero choyandama: ≥ 92%
Kuchuluka kwa zinthu: 0.13g/cm³- 0.15g/cm³
Tinthu kukula: D90 ≤ 100 μ m
Kuchuluka kwenikweni: 0.24g/cm³- 0.27g/cm³
Mphamvu yokakamiza: 750psi

Ntchito zazikulu za ma microspheres agalasi opanda kanthu:
1. Kusintha kwa nayiloni, PP, PBT, PC, POM, PVC, ABS, PS ndi mapulasitiki ena kungathandize kusintha kusinthasintha kwa madzi, kuthetsa kukhudzana ndi ulusi wagalasi, kuthana ndi kupotoka kwa ulusi, kukonza mphamvu zoletsa moto, kuchepetsa kugwiritsa ntchito ulusi wagalasi, ndikuchepetsa ndalama zopangira.
2. Kudzaza PVC yolimba, PP, PE, kupanga ma profiles, mapaipi ndi mapepala, kungapangitse kuti zinthuzo zikhale zokhazikika bwino, kusintha kuuma ndi kutentha kosagwirizana ndi kutentha, kusintha magwiridwe antchito a mtengo wa chinthu, kusintha magwiridwe antchito opangira ndikuchepetsa ndalama.
3. Yodzazidwa ndi PVC, PE ndi zingwe zina ndi zinthu zotetezera kutentha, imatha kukweza kukana kwa kutentha kwa chinthucho, kutchinjiriza, kukana kwa asidi ndi alkali ndi zinthu zina komanso magwiridwe antchito opangira zinthu, kuwonjezera kutulutsa ndikuchepetsa ndalama.
