Boron nitride ndi mtundu wosavuta kwambiri wa ma macrorolecular ndi zonse ziwiri za hexagonal ndi mawonekedwe a cubic.
Ndi mtundu wa chinthu chokhala ndi kutentha kwambiri, kuwononga chilengedwe, kukhazikika kwamphamvu komanso mitundu yabwino.
Kutentha kwake kwa oxidation kumatha kufika ku 1000 ° C, ndipo kumakhala ndi mafuta abwino kutentha kwambiri, chifukwa chake ndi mtundu wa kutentha kwambiri kwa mafuta odzola.

Amagwiritsidwa ntchito mafuta olimbika kwambiri, otamandidwa anti-owonjezera owonjezera, owonjezera opanga mapangidwe a ceramic.
Ogwiritsidwa ntchito mu electrolysis ndi kukana zinthu zakutentha kwambiri;
Ogwiritsidwa ntchito pochita zishango ku Arospace;
Ogwiritsidwa ntchito ngati othandizira kumasulidwa kuti azikhala achitsulo komanso mafuta ojambula a waya;
Ntchito Titha Kupereka
1) Contrated mgwirizano wovomerezeka akhoza kusankhidwa
2) Mgwirizano wachinsinsi ungasainidwe
3) Masiku asanu ndi awiri obweza ngongole
Chofunika kwambiri: Sitingangopereka malonda okha, koma njira yaukadaulo yaukadaulo!
Ndife opanga, fakitale yathu ili ku Shandong, koma titha kuperekanso munthu kuti asiye kugula kwa inu!
T / T (Tchalitchi), Western Union, Ngongole, BTC (Bitcoin), etc.
≤25kg: mkati mwa masiku atatu ogwira ntchito atalandira. > 25kg: sabata imodzi
Kupezeka, titha kupereka zitsanzo zazing'ono zaulere za cholinga chabwino!
1kg pa Thumba la FPRS zitsanzo, 25kg kapena 50kg pa ngoma pa Drum, kapena momwe mukufunira.
Sungani chidebe chomwe chatsekeka mwamphamvu pamalo owuma, ozizira komanso ozizira.
