Ngā Take me ngā Otinga Noa i roto i te Sintering Ouma Niho

Ko te whakahaere i tētahi taiwhanga niho he mea nui te mahi a tō oumu whakahinuhinu. Ina hē te mahi—te rerekētanga o te tae, te mura kāore i oti, ngā pakaru, te poke—ehara i te mea ko ngā rauemi anake ka pau. Ka pau hoki te wā, te ingoa pai, me te whakawhirinaki o te manawanui.

Ko te wero, he ahua matapōkere te nuinga o ngā raruraru sintering. Ka mura pai tetahi puranga. Kāore tetahi e mura. Engari he māmā ake te pono: ko te nuinga o ngā raruraru e ahu mai ana i tētahi huinga iti o ngā pūtake ka taea te whakahaere ina mārama koe ki a rātou.

Ka whakamāramahia e tēnei aratohu ngā raruraru e ono e kitea ana i roto i ngā taiwhanga niho nui, ngā take e puta ai, me pēhea te whakaoti i aua raruraru. Ahakoa kei te rapu raruraru koe i tētahi raruraru o nāianei, kei te rapu rānei koe ki te ārai i ngā raruraru i mua i te tīmatanga, mā te mārama ki ēnei kaupapa matua ka āwhina i a koe ki te whakatutuki i ngā hua e rite ana, e matapaetia ana.

Ngā Raru Matua e Ono o te Sintering—Me pēhea te Whakatika

1. Te Hurihanga Tae

Te āhua: Ka puta mai ngā whakahoutanga i te oumu me ngā atarangi hē—pōuri rawa, mārama rawa, rerekē rānei ngā tae o raro (whero, kōwhai, hina).

Te take: Ngā tae kua pau te wā, te roa o te rumaki he, te rerekētanga o te pāmahana whakamahana (ahakoa he mea nui te 20°C), te rerekētanga o te tauira tae, te rerekētanga o te puranga rauemi mata, te tikanga whakahaere kāore i te paerewa.

2. Te Whakakānga Kore-oti (Te Whakakānga-kore)

Te āhua: He pai te āhua o ngā whakahoutanga engari kāore i te kaha te hanganga. Ka ngawari te pakaru, ka piko i te wā kāore e tika ana, ā, ka rahua te whakamātautau kaha.

He aha i tupu ai: He iti iho te pāmahana tuturu o te oumu i te mea e whakaatuhia ana, he kore pumau te pūnaha hiko e hua ai ngā rerekētanga o te ngaohiko, he kore rānei i tino pai te whakarite o ngā pihi whakakā mō tō tauira oumu me te momo paura.

3. Ngā Kapiti me ngā Whatiwhati

Te āhua: Ka puta mai ngā kapiti angiangi (i ētahi wā ka kitea noa i raro i te whakanui) e whiti ana mai i ngā pūwāhi ahotea. Ka ngoikore haere te whakaora i te roanga o te wā.

He aha i tupu ai: Kāore i te rawaka te wā maroke i muri i te paninga, he tere te huringa o te pāmahana i te wā e whakamatao ana, he nui rawa te huri i waenga i ngā huringa tahu, he ngoikore te hoahoa matua/ātete, he maha rawa rānei ngā huringa tahu e whakahokia ana.

4. Te Parahanga o te Mata

Te āhua: Ka puta he ira mā, he paru kōwhai/parauri, he tae kakariki rānei ki te mata whakaora—kāore ēnei e memeha nā te mea kua piri ki te mata.

Te take e tupu ai: Te pānga o muri i te paru ki ngā mata kua poke, te marere o ngā poro zirconia mai i ngā taputapu mira, te puehu/toenga o te rūma oumu, ngā wāhanga whakamahana oumu kua pirau rānei (ngā tokotoko SiMo, SiC rānei).

5. Te Whakatōtōtanga Kore Taurite

Te āhua: He rerekē ngā mātotoru o ngā rohe rerekē o te puranga kotahi. He tino pai ngā whakaora o waenganui; he iti ake te kaha o ngā taha (tērā rānei).

Te take: Kāore i te ōrite te tohatoha matūriki/whakaora i roto i te oumu, te koretake o te tohanga hau i roto i te rūma, te hoahoa oumu rānei me ngā wāhi wera me ngā rohe matao.

6. Te Hurihanga me te Taurite Kino

Te āhua: Whai muri i te whakahinuhinu, kua rerekē te āhua o te whakaora, ā, kāore e uru ki te niho kua whakaritea. Kua he ngā taha, kua piko paku rānei te karauna katoa.

Te take: He ngoikore, he kore rānei e tautokona te hoahoa matua/ārai, he tino teitei rawa te pāmahana o te whakamahana, he hē rānei te tūnga whakaora i runga i te paepae oumu i te wā e tahuna ana.

He aha te Hiranga o ēnei Raru

He pānga whakarara tō ia o ēnei take:

·   Ko te rerekētanga o te tae ka arahi ki te kore e makona o te manawanui me te hanga hou.

·   Ka puta ngā ngoikoretanga haumanu ohorere (ngā maramara, ngā whati i roto i te waha) mēnā kāore i te tino wera.

·   Ka horapa ngā kapiti i roto i te wā, ā, ka mutu, ka kore e taea te whakaora.

·   Me hanga anō te poke o te mata, ā, ka kino hoki te āhua.

·   Mā te kore taurite o te sintering ka puta he rerekētanga o te puranga me ngā hua ka kore e taea te matapae.

·   Ka hua ake te whakarerekētanga o te āhua kāore e pai te taunga, ngā raruraru nohoanga, me ngā hanga anō.

Ko te aho matua? Ka taea te ārai i ēnei mea katoa mā te mārama, te aroturuki, me te whakahaere tukanga.

Te Whakamahi i te Tino Pai mai i tō Tukanga Sintering

Ko ngā taiwhanga e tutuki ana i te ōritetanga sintering teitei rawa atu he rite tonu ki ētahi mahi noa:

·   Ine me te tuhi: Aroturuki i te pāmahana o te oumu, ngā wā tahunga, me ngā hua puranga.

·   Whakapūmautia ngā tikanga: Whakamahia ngā SOP tuhituhi mō ia taahiraa.

·   Tiakina wawetia: Whakakapia ngā wāhanga o te oumu, horoia ngā rūma, whakahoutia ngā otinga paru.

·   Whakamātauria i mua i te whakahaerenga katoa: Whakahaerehia ngā whakamātautau tauira hei manatoko i tō tukanga.

·   Arotakehia ia toru marama: Tātarihia ō raraunga pana me te tautuhi wawe i ngā au.

Mā ēnei tikanga ka hurihia te mahi sintering hei tukanga e taea te matapae, e taea te whakahaere.

Tā mātou Otinga

Mena kei te pāngia koe e tētahi o ēnei wero whakawera, ko te pūtake o te take he whakahaere oumu, he pumau pāmahana, he rite tonu rānei ki te tukanga. He mea hanga motuhake te oumu whakawera Globaldentex Q7 hei whakatika i ēnei take.

Kei roto i te Q7 te mana whakahaere pāmahana tino tika (±2°C), te sintering tino tere (60 meneti tae atu ki te arawhata me te whakamatao), ngā huānga whakamahana SiC kawemai pumau me te kore poke, me te whakatikatika pāmahana aunoa mō te tere whakamaroke, whakamahana, me te whakamatao ōrite. Kāore he huringa horoi e hiahiatia ana—ka tahuna tonu me te kore e heke te kounga.

Mena kei te hiahia koe ki te ako atu mō te whakapai ake a te Q7 i tō tukanga sintering, he pātai rānei āu mō tētahi o ngā take kua kapi i konei, tēnā whakapā mai.
