Iko kukonzeresa kwe tungsten kutumira kunze kwekutonga kuri kuuya kuzoshanda pane tungsten indasitiri

Chikamu chapfuura, Ministry of Commerce, yakabatana neGeneral Administration of Customs, yakapa chiziviso chakabatana kuchengetedza chengetedzo yenyika nezvido apo vachizadzisa mabasa epasi rose asiri ekuparadzira. Nemvumo yeHurumende Council, matanho akasimba ekudzora kunze kwenyika akaiswa pazvinhu zvine chekuita ne tungsten, tellurium, bismuth, molybdenum, uye indium. Kunyanya, zvinhu zvinodzorwa zvine chekuita netungsten zvinosanganisira ammonium paratungstate, tungsten oxides, mamwe asina kudzora tungsten carbides, chaiwo mafomu eyakasimba tungsten (kunze kwemagranules kana hupfu), chaiyo tungsten-nickel-iron kana tungsten-nickel-mhangura alloys, uye data uye matekinoroji pasi peiyo 40 kodhi zvinhu zvinodikanwa. 1C117.c, 1C117.d). Vese vanoshanda kunze kwenyika zvinhu izvi vanofanirwa kutevedzera Mutemo weExport Control wePeople's Republic of China uye Mitemo paKudzora Kutengeswa Kwezvinhu Zviviri-Kushandisa Zvinhu, vachinyorera nekuwana maredhimisheni ekunze kubva kune vane hunyanzvi vekutengeserana veState Council. Ichi chiziviso chinotanga kushanda nekukasira uye chinovandudza Export Control Rondedzero yeDual-Use Zvinhu zvePeople's Republic of China.

Tungsten Export Controls Haisi Kurambidzwa Kwakazara
Tungsten kutumira kunze kwenyika zvinodzora hazvireve kurambidzwa kwese kunze kwenyika asi zvinosanganisira akamisikidzwa manejimendi ezvimwe zvinhu zvine chekuita ne tungsten. Vatengesi kunze kwezvinhu izvi vanofanirwa kunyorera mvumo kubva kune vane hunyanzvi hwekutengesa zviremera veState Council zvinoenderana neExport Control Law uye Regulations pamusoro peExport Control yeDual-Use Items. Kutengeswa kunze kwenyika kunobvumirwa chete pakutevedzwa uye kubvumirwa.
Inogona Impact paMusika Wepamba
Zvinoenderana nedhata kubva kuTungsten-Molybdenum Cloud Commerce Platform, kutengeswa kunze kwenyika kweammonium paratungstate (APT), tungsten trioxide, uye tungsten carbide account yechikamu chinozivikanwa chese tungsten inotengeswa kunze kwenyika:
  • APT inotengeswa kunze kwenyika muna 2023 na2024 ingangoita matani mazana masere nematatu nemazana manomwe nemakumi masere nemaviri, zvichiteerana, imwe neimwe ichiverengera 4% yezvese tungsten zvinotengeswa kunze kwenyika.
  • Tungsten trioxide inotengeswa kunze kwenyika yaive matani zviuru zviviri nemazana matanhatu muna 2023 uye 3,190 matani muna 2024, ichikwira kubva pa14% kusvika 17% yezvese zvinotengeswa kunze kwenyika.
  • Tungsten carbide inotengeswa kunze kwenyika ingangoita 4,433 matani muna 2023 uye 4,147 matani muna 2024, kuchengetedza chikamu chingangoita makumi maviri nemaviri%.
Kuitwa kwe tungsten kudzora kunze kwenyika kuchaita kuti zvinhu izvi zvitarisire zvakanyanya uye maitiro emvumo, izvo zvinogona kukanganisa mashandiro evamwe vatengesi. Nekudaro, tichipihwa chikamu chidiki chezvinhu izvi zvinodzorwa mune yakazara tungsten kutengeswa kunze kwenyika, iko kukonzeresa kwemusika wepamusha we tungsten-yekuda simba uye maitiro emitengo anotarisirwa kuve mashoma. Iyi mutemo inogonawo kukurudzira mabhizinesi kuti atarise pahunyanzvi hwekuvandudza tekinoroji uye mhando yechigadzirwa kuti asangane nemisika yemunyika neyekunze.
Mhedzisiro yemitengo paTungsten Mitengo
Strategic Kukosha kweTungsten
Tungsten's high melting point, kuoma, conductivity, uye corrosion kuramba inoita kuti ive yakakosha mumaindasitiri epasi rose. Mukugadzirwa kwesimbi, tungsten inowedzera simba, kuoma, uye kupfeka kuramba, inoshandiswa zvakanyanya mumichina nekuvaka. Mune zvemagetsi, chinhu chakakosha chezvikamu, zvakabatanidzwa dunhu rinotungamira, uye echinyakare filaments. Mumuchadenga, tungsten alloys akakosha kune injini blades uye maroketi nozzles, anotsigira nzvimbo kuongorora. Muchiuto, tungsten alloys akakosha kune pfuti-kubaya projectiles, missile zvikamu, uye nhumbi dzokurwa, zvinokanganisa zvakanangana nekudzivirira kwenyika. Kuve nechokwadi chekugadzikana kweimba tungsten kupihwa kwakakosha kune kuchengetedzwa kwenyika.
Mhedzisiro Yenguva pfupi uye Yakareba
Nenguva pfupi, zvidzoreso kunze kwenyika zvichaderedza kupihwa kweChina tungsten kumisika yepasirese, zvingangokanganisa mareti ekudiwa-kwenguva refu uye kutyaira mitengo yetungsten yepasirese ichikwira nekuda kwekuomarara kuri kuderera. Nekufamba kwenguva, zvidzoreso izvi zvinosimudzira kukwidziridzwa kwemaindasitiri, kukurudzira kudyara kweR&D, kushandiswa zvakanaka kwezviwanikwa, uye kusimudzira zvigadzirwa zvemhando yepamusoro kusimudzira simba reChina muindasitiri yetungsten.
Iko Kubata kweUS-China Tariff Hondo PANE TUNSTEN PRODUCTS
Global Tungsten Statistics
Sekureva kweUSGS, nzvimbo dzepasi rose tungsten dzakachengetwa muna 2023 dzaive matani 4.4 miriyoni, zvichikwira 15.79% gore negore, neChina ichitora 52.27% (2.3 miriyoni matani). Kugadzirwa kwe tungsten pasi rose kwaive 78,000 matani, pasi ne2.26%, neChina ichipa 80.77% (63,000 matani). MaChina echinyakare data anoratidza akasiyana tungsten kutumira kunze kwenyika, kusanganisira tungsten ores, tungstic acid, tungsten trioxide, tungsten carbides, uye akasiyana tungsten zvigadzirwa. Muna 2024, China yakatumira kunze 782.41 matani eAPT (pasi 2.53%, 4.06% yezvose zvinotengeswa kunze kwenyika), 3,189.96 matani e tungsten trioxide (kusvika 18.19%, 16.55% yezvose zvinotengeswa kunze kwenyika), uye 4,146.76 matani e4,146.76 emotokari ye6. zvese zvinotengeswa kunze kwenyika).
