I-Metal Powder Water Atomizer Yee-Alloys ZeCopper zeSilivere zeSilivere zeSilivere zeSilivere

Kusekho iziphene ezininzi ekuqondeni itekhnoloji yokuprinta ye-3D kuzo zonke iinkalo zoshishino lwaseTshayina. Xa sijonga imeko yophuhliso lokwenyani, ukuza kuthi ga ngoku ukuprinta kwe-3D ayikafikeleli kwimveliso evuthiweyo, ukusuka kwizixhobo ukuya kwiimveliso ukuya kwiinkonzo ezisekwinqanaba "lethoyi eliphambili". Nangona kunjalo, ukusuka kurhulumente ukuya kumashishini aseTshayina, amathuba ophuhliso lwetekhnoloji yokuprinta ye-3D ayaziwa ngokubanzi, kwaye urhulumente kunye noluntu ngokubanzi banikela ingqalelo kwimpembelelo yetekhnoloji yezixhobo zokuprinta ze-3D kwixesha elizayo kwimveliso ekhoyo, uqoqosho, kunye nemodeli zokuvelisa zelizwe lam.

Ngokwedatha yophando, okwangoku, imfuno yelizwe lam yetekhnoloji yokuprinta ye-3D ayigxininiswanga kwizixhobo, kodwa ibonakala kwiindidi ezahlukeneyo zezinto ezisetyenziswayo zokuprinta ze-3D kunye nemfuno yeenkonzo zokucubungula ii-arhente. Abathengi bemizi-mveliso ngabona baphambili ekuthengeni izixhobo zokuprinta ze-3D kwilizwe lam. Izixhobo abazithengayo zisetyenziswa kakhulu kwiinqwelomoya, kwiinqwelomoya, kwiimveliso ze-elektroniki, kwezothutho, kuyilo, kubuchule benkcubeko nakwamanye amashishini. Okwangoku, amandla afakiweyo eeprinta ze-3D kumashishini aseTshayina amalunga nama-500, kwaye izinga lokukhula ngonyaka limalunga nama-60%. Nangona kunjalo, ubungakanani bemarike yangoku bumalunga ne-100 yezigidi zeeyuan ngonyaka. Imfuno enokubakho ye-R&D kunye nophuhliso lwezixhobo zokuprinta ze-3D ifikelele phantse kwi-1 yeebhiliyoni zeeyuan ngonyaka. Ngokuthandwa kunye nenkqubela phambili yetekhnoloji yezixhobo, isikali siya kukhula ngokukhawuleza. Kwangaxeshanye, iinkonzo zokucubungula eziphathisiweyo ezinxulumene nokuprinta kwe-3D zithandwa kakhulu, kwaye iiarhente ezininzi zokuprinta ze-3D Inkampani yezixhobo ikhulile kakhulu kwinkqubo yokusila i-laser kunye nokusetyenziswa kwezixhobo, kwaye inokubonelela ngeenkonzo zokucubungula zangaphandle. Ekubeni ixabiso lesixhobo esinye ngokubanzi lingaphezulu kwe-5 yezigidi zeeyuan, ukwamkelwa kwemarike akuphezulu, kodwa inkonzo yokucubungula i-arhente ithandwa kakhulu.

Uninzi lwezixhobo ezisetyenziswa kwizixhobo zokucola isinyithi ze-3D printing metal atomization zelizwe lam zibonelelwa ngokuthe ngqo ngabavelisi be-prototyping abakhawulezayo, kwaye ukunikezelwa kwezinto eziqhelekileyo akukaqaliswa, nto leyo ebangela iindleko eziphezulu kakhulu zezinto. Kwangaxeshanye, akukho phando malunga nokulungiswa komgubo olunikezelwe kushicilelo lwe-3D eTshayina, kwaye kukho iimfuno ezingqongqo malunga nokusasazwa kobukhulu bamasuntswana kunye nomxholo weoksijini. Ezinye iiyunithi zisebenzisa umgubo we-spray oqhelekileyo endaweni yoko, ongenakusetyenziswa kakhulu.

Uphuhliso kunye nokuveliswa kwezinto ezisebenziseka lula yeyona nto iphambili ekuphuhliseni ubuchwepheshe. Ukusombulula iingxaki zokusebenza kunye neendleko zezinto kuya kukhuthaza ngcono uphuhliso lwetekhnoloji yokushicilela ngokukhawuleza eTshayina. Okwangoku, uninzi lwezinto ezisetyenziswa kubuchwepheshe bokushicilela ngokukhawuleza be-3D kwilizwe lam kufuneka zingeniswe zivela kwamanye amazwe, okanye abavelisi bezixhobo batyale amandla amaninzi kunye nemali ukuziphuhlisa, ezibiza kakhulu, nto leyo ebangela ukunyuka kweendleko zemveliso, ngelixa izinto zasekhaya ezisetyenziswa kulo matshini zinamandla aphantsi kunye nokuchaneka. . Ukubekwa kwezixhobo zokushicilela ze-3D kwindawo ethile kubalulekile.

Iipowder ze-alloy ze-titanium kunye ne-titanium okanye iipowder ze-superalloy ezisekwe kwi-nickel kunye ne-cobalt ezinomxholo ophantsi we-oksijini, ubungakanani be-particle encinci kunye ne-sphericity ephezulu ziyafuneka. Ubungakanani be-particle ye-powder buyi-mesh eyi-500 ikakhulu, umxholo we-oksijini kufuneka ube ngaphantsi kwe-0.1%, kwaye ubungakanani be-particle buyafana Okwangoku, i-powder ye-alloy ephezulu kunye nezixhobo zokwenza izinto zisaxhomekeke kakhulu ekungenisweni kwamanye amazwe. Kumazwe angaphandle, izinto ezikrwada kunye nezixhobo zihlala zihlanganiswa kwaye zithengiswa ukuze kufumaneke inzuzo eninzi. Ukuthatha i-powder esekwe kwi-nickel njengomzekelo, ixabiso lezinto ezikrwada limalunga ne-200 yuan/kg, ixabiso leemveliso zasekhaya ngokubanzi liyi-300-400 yuan/kg, kwaye ixabiso le-powder engeniswayo lidla ngokuba ngaphezulu kwe-800 yuan/kg.

Umzekelo, impembelelo kunye nokuguquguquka kokwakheka kwepowder, ukufakwa kunye neempawu zomzimba kwitekhnoloji enxulumene nezixhobo zokugaya ipowder ze-atomization zesinyithi ze-3D. Ke ngoko, ngenxa yeemfuno zokusetyenziswa komxholo ophantsi weoksijini kunye nomgubo omncinci we-particle, kusafuneka kwenziwe umsebenzi wophando ofana noyilo lokwakheka kwepowder ye-titanium kunye ne-titanium alloy, iteknoloji yokugaya ipowder ye-atomization yegesi yomgubo omncinci we-particle, kunye nempembelelo yeempawu zepowder ekusebenzeni kwemveliso. Ngenxa yokuthintelwa kwetekhnoloji yokugaya eTshayina, kunzima ukulungiselela ipowder ecoliweyo okwangoku, isivuno sepowder siphantsi, kwaye umxholo weoksijini kunye nokunye ukungcola kuphezulu. Ngexesha lenkqubo yokusebenzisa, imeko yokunyibilika kwepowder ithambekele ekungalinganini, okubangela umxholo ophezulu we-oxide inclusions kunye neemveliso ezixineneyo kwimveliso. Iingxaki eziphambili zepowders ze-alloy zasekhaya zikwimeko yomgangatho wemveliso kunye nokuzinza kwebhetshi, kubandakanya: ① ​​ukuzinza kwezixhobo zepowder (inani lezinto ezifakiweyo, ukufana kwezixhobo); ② Uzinzo lomzimba wepowder (ukusasazwa kobungakanani be-particle, i-formology yepowder, ukugeleza, umlinganiselo okhululekileyo, njl.njl.); ③ ingxaki yesivuno (isivuno esiphantsi somgubo kwicandelo elincinci lobukhulu bamasuntswana), njl.
