Ceramic Injection Molding Cold Sintering (CS)

Mfundo ndondomeko yajekeseni wa ceramicCS luso ndi kuwonjezera pang'ono amadzimadzi njira kwa ufa ceramic kunyowetsa particles, ndi zinthu pamwamba pa ufa ndi decomposed ndi pang'ono kusungunuka mu yankho, potero kupanga madzi gawo pakati pa tinthu-tinthu mawonekedwe. Ikani ufa wonyowa mu nkhungu, tenthetsani nkhungu, ndikugwiritsanso ntchito mphamvu yaikulu nthawi yomweyo. Pambuyo posunga kukakamiza ndikusunga kwa nthawi yayitali, zinthu zaceramic zowuma zimatha kukonzekera. Panthawi imeneyi, ndi microstructure wazinthu za ceramicchimasanduka. monga chithunzi chikuwonetsa.

Ngakhale kuti pali zinthu zambiri zomwe zimakhudza ndondomeko ya CS, zipangizo zomwe zimagwiritsidwa ntchito ndi teknolojiyi ndizosavuta. , Zida za ceramic CS makamaka zimaphatikizapo makina osindikizira wamba, mbale ziwiri zotenthetsera zomwe zimayikidwa pamwamba ndi pansi pa makina osindikizira, ndi jekete yotenthetsera yoyendetsedwa ndi magetsi imathanso kukulungidwa mozungulira nkhungu kuti itenthe ufa.

Oscillating Pressure Sintering for Ceramic Injection MoldingCIM (OPS)

Matekinoloje osiyanasiyana omwe alipo akugwiritsa ntchito kuthamanga kwanthawi zonse. Kukhazikitsidwa kwa static pressure pa nthawi yandondomeko ya sinteringkumathandiza kuthetsa pores ndi kusintha kachulukidwe za ceramic, koma n'kovuta kwathunthu ionize ndi covalently kugwirizana ziwiya zadothi wapadera. Kupatulapo pores mkati mwazinthuzo kumakhalabe ndi zoletsa zina pakukonzekera kofunikira kwamphamvu kwambiri, kulimba kwambiri, kuuma kwakukulu komanso zida zodalirika kwambiri.
Zifukwa zazikulu zochepetsera HP static pressure sintering zikuwonetsedwa muzinthu zitatu izi:

• ① Asanayambe sintering komanso koyambirira kwa sintering, kupanikizika kosalekeza sikungathe kuzindikira kukonzanso kwa tinthu tating'ono ta ufa mu nkhungu kuti tipeze kachulukidwe kake;
• ② Pakati ndi mtsogolo masitepe a sintering, kutuluka kwa pulasitiki ndikuchotsa ma agglomerate akadali ochepa, ndipo n'zovuta kukwaniritsa yunifolomu kachulukidwe wa zinthu;
• ③ M'magawo omaliza a sintering, ndizovuta kuchotseratu ma pores otsalira ndikupanikizika kosalekeza.

Kuti izi zitheke, gulu lofufuza la wolembayo lidapereka lingaliro latsopano lokhazikitsa kukakamiza kwamphamvu kwa oscillating kuti m'malo mwa kupanikizika komwe kulipo kosalekeza munjira yopangira ufa, ndipo adatsogolera pakupanga ukadaulo wa OPS ndi zida padziko lapansi. Pansi pa kupanikizika kwakukulu kosalekeza, kupanikizika kwa oscillating ndi mafupipafupi osinthika ndi matalikidwe amapangidwa pamwamba kuti asandutse "mphamvu yakufa" yomwe imagwiritsidwa ntchito mu sintering yachikhalidwe kukhala "mphamvu". Chithunzi chojambula cha oscillating pressure coupling chipangizo ndi mfundo ikuwonetsedwa mu chithunzichi.

Ukadaulo watsopano wa OPS uli ndi maubwino apadera okonzekera zida zokhala ndi kachulukidwe kakang'ono (kuposa 99.9% ya kachulukidwe kamalingaliro), zolakwika zochepa, komanso mawonekedwe owoneka bwino ambewu. ndi kudalirika kumapereka njira yatsopano.
