Boron carbide, oo loo yaqaan dheeman madow, formula B4C, sida caadiga ah budada madow. Waa mid ka mid ah saddexda shay ee ugu adag ee la yaqaan. (labada kale waa dheeman, boron nitride cubic), oo loo isticmaalo hubka, dharka aan xabadu karin iyo codsiyada warshadaha badan ee baabuurta taangiyada. Adaggeeda Mohs waa 9.3.
-Darsiga kiimikada lidka ku ah;
-qalabka u adkaysta;
Waxaa loo isticmaalaa in lagu shiido laba-weji ee LED iyo khafiifinta iyo polishing of safayr ku salaysan taarikada fidinta LED, warshadaha difaaca qaranka, warshadaha refractories warshadaha nuclear iyo qalabka kale ee dhoobada injineernimada, alxanka alaabta iwm.
Adeeg aan bixin karno
1) Qandaraaska rasmiga ah waa la saxiixi karaa
2) Heshiis qarsoodi ah waa la saxiixi karaa
3) Todoba maalmood oo dammaanad celin ah
Muhiimad badan: waxaan ku siin karnaa ma aha oo kaliya badeecada, laakiin adeegga xalka tignoolajiyada!
Waxaan nahay soo saaraha, warshadeena waxay ku taal Shandong, laakiin sidoo kale waxaan ku siin karnaa hal adeeg iibsi joogsi ah!
T/T (kala iibsiga telex), Western Union, MoneyGram, BTC(bitcoin), iwm.
≤25kg: saddex maalmood oo shaqo gudahood ka dib markii lacagta la helay. ＞25kg: hal todobaad
La heli karo, waxaan ku siin karnaa muunado yar yar oo bilaash ah ujeedada qiimeynta tayada!
1kg halkii bac fpr muunado, 25kg ama 50kg halkii durbaan, ama sida aad u baahan tahay.
Ku kaydi weelka si adag u xiran meel engegan, qabow oo si fiican u hawo leh.
