1. Impembelelo yomgubo wezinto ezikrwada
Eyona nto ibalulekileyo kwi-alumina wear-resistant accurate ceramics yi-high-purity alumina powder. Ukusebenza kwayo kunye nomxholo wayo kunempembelelo enkulu kwi-alumina wear-resistant accurate ceramics. I-ceramic powder ngokuqinisekileyo iya kungenisa ukungcola ngexesha lenkqubo yokulungiselela, kwaye ukungcola kwezinto eziphilayo kuya kutshiswa ngexesha lenkqubo yokusila, kwenze ii-pores ezingaqhelekanga ngexesha lenkqubo yokuxinana; ukungcola okungaphiliyo kuya kusabela kwi-ceramic powder kubushushu obuphezulu okanye kwi-matrix Ukwenziwa kwee-microcracks. Ezi ngcola zinempembelelo ebalulekileyo ekuxinweni kwe-alumina ceramics. Ubungakanani be-particle ye-powder yezinto ezikrwada bunempembelelo enkulu ekusebenzeni kwemveliso. Kuphela xa izinto ezikrwada zilungile ngokwaneleyo, imveliso yokugqibela esintered inokwenza isakhiwo se-microcrystalline, esenza ukuba sibe nokumelana okuhle nokuguguleka. Ke ngoko, ii-alumina powders ezicocekileyo nezicoliweyo ziyimfuneko ebalulekileyo yokulungiselela ii-alumina ceramics ezinganyangekiyo.
2. Impembelelo yendlela yokubumba
Indlela yokuvelisa kunye nenani elikhulu lezifundo zibonise ukuba iiseramikhi ze-alumina ezinemibhobho ephantsi, ezinoxinano oluphezulu zineempawu ezintle zesakhiwo. Uxinano oluphezulu luthetha ukuba iinkozo zekristale emzimbeni weseramikhi zilungelelaniswe ngokusondeleyo, kwaye akulula ukuphuhlisa indawo yokuphumelela etshabalalisayo xa ziphantsi kwemithwalo yangaphandle yokusingqongileyo okanye izinto ezirhabaxa.
Ukuze kufunyanwe indlela yokubumba umzimba we-ceramic enoxinano oluphezulu kubalulekile. Ii-ceramics ezingagugiyo ze-Alumina ngokubanzi zinokwenziwa ngokucinezela okomileyo, ukucinezela oku-isostatic, ukuphosa i-hot die kunye nezinye iindlela. Iindlela ezahlukeneyo zokunyibilikisa zineempawu ezahlukeneyo kwaye zinempembelelo eyahlukileyo kwiimpawu zokunyibilikisa kunye nesakhiwo se-microstructure ye-alumina ceramics.
Iimveliso ezineemilo ezahlukeneyo zihlala zicutshungulwa nge-grouting okanye i-hot-press casting, kwaye iimveliso ezineemilo ezilula zenziwa ngokucinezela okomileyo.
3. Isiphumo sokusila
Ukusila yinqanaba elibalulekileyo ekulungiseleleni izinto zeseramikhi, kwaye umoya wokusila unempembelelo enkulu ekulungiseleleni izinto zeseramikhi. Ubushushu obuphezulu kakhulu bokutshisa okanye ixesha elide kakhulu lokugcinwa kuya kukhuthaza ukukhula kweekristale, okwenza izinto ezintle eziluhlaza zikhule zibe ziinkozo ezirhabaxa kubushushu obuphezulu, kwaye umxholo wesigaba solwelo uya kwanda. Oku akunciphisi nje kuphela amandla, kodwa kunciphisa nokumelana nokuguguleka. Kakade ke, ukuba ubushushu buphantsi kakhulu, umzimba osila awuyi kuba mkhulu, kwaye ukumelana nokuguguleka kwemveliso akuyi kuba kuhle.
Ukushisa isitofu esinombane ogqwesileyo kunokulawula ngokuchanekileyo inkqubo yokufudumeza, yokubamba kunye nokupholisa, edlala indima ebalulekileyo ekuphuculeni ukumelana nokuguguleka kweeseramikhi, kodwa iindleko zokutshiswa kunye nokusetyenziswa kwezinto ezinganyangekiyo kwi-oven yombane kuphezulu kunezo zemigodi yamalahle.
4. Isikhawulezisi sokutsha
Ukucoca ngokufanelekileyo kunceda ekunciphiseni ubushushu ngexesha lokucoca, kuphucule ulwakhiwo lwe-microstructure yeeseramikhi, kwaye kuphucule iimpawu zoomatshini, ngaloo ndlela kuphucule ngempumelelo ukumelana nokuguguleka kweeseramikhi ezimelana nokuguguleka ze-alumina.
Umenzi we-CHEMSHUN CERAMIC unika ingqalelo engqongqo kwiiithayile zokunxiba ze-alumina ceramicumgangatho wemveliso. Wamkelekile kwimibuzo.
