Muindasitiri yehuni,mapanga etungsten carbideZvishandiso zvinoshandiswa pazvishandiso zvakakosha chaizvo, nekuomarara kukuru, kupinza, uye kugara kwenguva refu, chii chinoita kuti ive banga riri nani? Ehe, zvinhu zvacho ndizvo zvichave chikonzero chikuru, pano, tinotsanangura kubva pazvinhu zvakakosha zvemashizha etungsten caribide, kuti ndikuzivisei chikonzero.
Zvinhu zvikuru zvekushandisa pakugadzira matanda eCarbide zvinosanganisira chikamu chakaoma (carbides dzakasimba zvakanyanya) uye chikamu chekubatanidza (simbi inobatanidza), chinowedzerwa nezvimwe zvinhu kuti zviite kuti zvinhu zvishande zvakanaka. Magadzirirwo chaiwo uye mabasa acho ndeaya anotevera:
I. Zvinhu Zvikuru Zvisina Kugadzirwa
1. Chikamu Chakaoma (85%–97%)
Tungsten Carbide (Chigadziko cheKufukidza):
- Basa Guru: Rinopa kuomarara kwakanyanya (HRA 89–94) uye kuramba kupfeka. Rinoumba 70%–97% yechikamu chakaoma.
- Mhedzisiro yeSaizi yeZviyo:
Tsanga Dzakakora (3–5μm): Kusimba kwakanyanya (Transverse Rupture Strength ≥2.2 GPa), yakakodzera kushandiswa pakugadzira matanda akaomarara (semuenzaniso, kucheka miti yakaoma).
Fine Grain (0.5–1μm): Kuomarara kwakawedzera (HRA 93.5), kuramba kupfeka ↑30% (zvinosarudzwa pakushandisa maturusi ekupedzisa).
Titanium Carbide (TiC) / Tantalum Carbide (TaC):
- Basa: TiC inowedzera kuomarara kwetsvuku (kuramba kusvika 1000°C); TaC inonatsa chimiro chezviyo uye inodzivirira kupisa kutsemuka (semuenzaniso, pakugadzirisa matanda ehuni akaputirwa nelaminate).
- Huwandu hwekuwedzera: 5%–10% (TiC), 3%–5% (TaC). Huwandu hwakawandisa hunoderedza kuomarara.
2. Chikamu chekubatana (3%–15%)
Cobalt (Komunisheni):
- Basa Guru: Rinowedzera kusimba. Kuwedzera kwehuwandu hweCo kunowedzera kuramba kwechinhu (Transverse Rupture Strength inosvika 2.2 GPa pa15% Co).
- Muganho: Zviri mukati >12% zvinoderedza kusakara (kuomarara kunoderera kusvika ~HRA 89).
Nickel (Ni):
- Basa: Inotsiva Co kuderedza mutengo, inopa ngura iri nani (yakakodzera huni dzine hunyoro >15%).
- Kushanda: Kusimba kwechinhu ichi kunosvika 80% yezvakaenzana neCo-based, kuomarara kwechinhu ichi HRA 89.5 (sarudzo yemuchina unodhura).
II. Hukama Pakati Pekuumbwa Kwezvinhu Nekushanda Kwezvishandiso
Kushanda (kuomarara, kuomarara, kuramba kupfeka) kwezvishandiso zvekugadzira matanda zve carbide kunotsanangurwa zvakananga ne WC/Co ratio, mhando dzekuwedzera, uye saizi yetsanga. Hukama hwakakosha hwekugadzirwa-kushanda uye data rekuyedza rinotsigira zvakapfupikiswa pazasi:
| Chirongwa chekuumbwa | Kuoma (HRA) | Simba reKuputika kweTransverse (MPa) | Chiratidzo Chekuramba Kupfeka (Hwaro hwekutanga = 100) | Mamiriro Anoshanda |
| WC 94% + Co 6% | 92.5 | 1,500 | 100 | Kupedzisa (MDF/Bhodhi reZvidimbu) |
| WC 88% + Co 12% | 89 | 2,200 | 75 | Kukwesha (Huni Dzakaoma/Huni Dzakakora) |
| WC 85% + Co 10% + TaC 5% | 91.2 | 1,800 | 110 | Kucheka Nekukurumidza (Matanda Akacheneswa) |
| WC 90% + Ni 10% | 89.5 | 1,700 | 80 | Matanda ane hunyoro >15% (Anodzivirira ngura) |
Sezvakakurukurwa muzvinyorwa zvakapfuura, kuwedzera kwemitengo yezvinhu zvekushandisa zvecarbide muna 2025 kunokonzerwa nekusawirirana kwekudiwa kwezvinhu, kuronga zviwanikwa, makwikwi epasi rose, uye kuvandudzwa kwemaindasitiri. Kudzikira kwemitengo kwakanyanya hakugoneke munguva pfupi. Inzwa wakasununguka kubata.Chengdu Huaxin Carbide yemibvunzo yemitengo uye mhinduro dzezvishandiso zvecarbide kumaindasitiri akasiyana-siyana.
Nezve Huaxin: Tungsten Carbide Cemented Slitting Mapanga Mugadziri
CHENGDU HUAXIN CEMENTED CARBIDE CO., LTD inyanzvi mupi wezvigadzirwa zve tungsten carbide, zvakaita semapanga ekugadzira matanda e carbide, mapanga e carbide denderedzwa ekuchekerera matanda efodya nefodya, mapanga akatenderera ekuchekerera makadhibhodhi ane corugat, mapanga e razor ane maburi matatu/mashizha ane maburi ekurongedza, tepi, kucheka firimu rakatetepa, mapanga ekucheka fiber eindasitiri yemachira nezvimwewo.

Ehe, taura nesu, mapanga emuindasitiri anowanikwa mumhando dzakasiyana-siyana, kusanganisira mapanga epamusoro, mapanga edenderedzwa epasi, mapanga ane serrated / tooth, mapanga anoboora akatenderera, mapanga akatwasuka, mapanga eguillotine, mapanga akapinza, mapanga erectangular razor, uye mapanga etrapezoidal.
Kuti tikubatsire kuwana banga rakanakisisa, Huaxin Cement Carbide inogona kukupa mienzaniso yakawanda yemashizha ekuyedza mukugadzirwa. Pakucheka nekushandura zvinhu zvinochinjika senge purasitiki, foil, vinyl, bepa, nezvimwewo, tinopa mapanga ekushandura anosanganisira mapanga ane mitsetse uye mapanga erazor ane mitsetse mitatu. Titumirei mubvunzo kana muchifarira mapanga emuchina, uye tichakupai chipo. Sampuli dzemapanga akagadzirwa nemaoko hadzipo asi munogamuchirwa kuodha huwandu hushoma hweodha.
Kune nzira dzakawanda dzinowedzera nguva yekubika mapanga nemapadza ako emuchina uye mapanga aripo. Tibatei kuti muzive kuti kurongedza kwakakodzera mapanga emuchina, mamiriro ekuchengetera, hunyoro uye tembiricha yemhepo, uye mamwe machira ekudzivirira mapanga enyu uye kuchengetedza kushanda kwawo pakucheka.
