Kupukuta kwa Tungsten Carbide Products

Vacuum sintering zikutanthauza kuti ufa, ufa compacts, kapena mitundu ina ya zipangizo zimatenthedwa pa kutentha koyenera m'malo opanda mpweya kuti zigwirizane ndi particles kupyolera mu kusamuka kwa atomiki. Sintering ndi kupanga porous ufa compacts kuti aloyi ndi zinthu zina ndi katundu.

Cemented carbide vacuum sintering ndi njira yopangira sintering pansi pa 101325Pa. Sintering pansi pa vacuum zikhalidwe zimachepetsa kwambiri cholepheretsa mpweya adsorbed pa ufa pamwamba ndi mpweya mu chatsekedwa pores pa kachulukidwe. Sintering imapindulitsa pakufalikira komanso kachulukidwe ndipo imatha kupewa zomwe zimachitika pakati pa chitsulo ndi zinthu zina mumlengalenga panthawi ya sintering. Kupititsa patsogolo luso lonyowa la gawo lamadzimadzi lomangira ndi gawo lolimba lachitsulo, koma vacuum sintering iyenera kulabadira kupewa kutayika kwa evapolt kwa cobalt.

Cemented carbide vacuum sintering nthawi zambiri imatha kugawidwa m'magawo anayi. Pali siteji yochotsera plasticizer, pre-sintering stage, high-temperature sintering stage, ndi siteji yozizira.

Ubwino wa vacuum sintering wa simenti carbide ndi:

1. Kuchepetsa kuipitsidwa kwa zinthu zomwe zimachitika chifukwa cha mpweya woipa wa chilengedwe. Mwachitsanzo, ndizovuta kwambiri kufikira mame osakwana 40 ℃ pamadzi a haidrojeni opangidwa ndi electrolysis, koma sikovuta kupeza digiri ya vacuum yotere;

2. Vacuum ndiye mpweya wabwino kwambiri wa inert. Pamene mipweya ina yobwezeretsa ndi inert siiyenera, kapena pazinthu zomwe zimakhala zosavuta kuwononga ndi carburization, vacuum sintering ingagwiritsidwe ntchito;

3. Vacuum imatha kusintha mphamvu yonyowa ya sintering yamadzimadzi, yomwe imapindulitsa kufota ndikuwongolera kapangidwe ka simenti ya carbide;

4. Vacuum imathandiza kuchotsa zonyansa kapena ma oxides monga Si, Al, Mg, ndi kuyeretsa zipangizo;

5. Vacuum ndi opindulitsa kuchepetsa adsorbed mpweya (otsalira mpweya pores ndi zochita mpweya mankhwala) ndipo ali ndi zotsatira zoonekeratu pa kulimbikitsa shrinkage mu siteji yotsatira ya sintering.

Kuchokera kuzinthu zachuma, ngakhale kuti zida zopangira vacuum sintering zimakhala ndi ndalama zambiri komanso zotsika mtengo pa ng'anjo, mphamvu yogwiritsira ntchito mphamvu imakhala yochepa, choncho mtengo wosungirako mpweya ndi wotsika kwambiri kuposa mtengo wa chilengedwe chokonzekera. Mu madzi gawo sintering pansi vakuyumu, ndi volatilization imfa ya binder zitsulo ndi nkhani yofunika, amene osati kusintha ndi kumakhudza chomaliza zikuchokera ndi kapangidwe ka aloyi, komanso kumalepheretsa sintering ndondomeko palokha.

Kupanga simenti ya carbide ndi njira yovuta. ZZBETTER amatenga tsatanetsatane kupanga mozama, mosamalitsa amazilamulira khalidwe simenti mankhwala carbide, ndipo amapereka njira zothetsera mavuto ntchito.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena KUTITUMIZIRA MAIL pansi pa tsambali.
