Ubuhlalu bengilazi obugcwele
Ubuhlalu bengilazi obugcwele buwuhlobo olusha lwezinto ezisetshenziswa kabanzi kanye nezakhiwo ezikhethekile ezakhiwe eminyakeni yamuva.Umkhiqizo wenziwe ngezinto zokusetshenziswa ze-borosilicate ngokusebenzisa ukucutshungulwa kobuchwepheshe obuphezulu, nosayizi wezinhlayiyana ezifanayo zobuhlalu obuncane bezingilazi.Ukwakheka kwamakhemikhali: SiO2 > 67%, Cao > 8.0%, MgO > 2.5%, Na2O < 14%, Al2O3 0.5-2.0, Fe2O3 > 0.15 kanye nokunye okungu-2.0%;Amandla adonsela phansi aqondile: 2.4-2.6 g / cm3;Ukubukeka: ingilazi ebushelelezi, eyindilinga, esobala ngaphandle kokungcola;Isilinganiso sokujikeleza: ≥ 85%;Izinhlayiya zikazibuthe akufanele zidlule u-0.1% wesisindo somkhiqizo;Okuqukethwe kwamabhamuza ebuhlalu bezingilazi kungaphansi kuka-10%;Ayiqukethe noma yiziphi izingxenye ze-silicone.
