Me pēhea te whiriwhiri i ngā rauemi tika mō te taputapu tapahi taimana

Ina tae ki te whakatutuki i te mahi tino pai i roto i te miihini, he mea nui te whiriwhiri i ngā rauemi o te taputapu tapahi taimana. Ko ngā taimana karaihe kotahi, PCD (PCD/CC rānei), me ngā taimana CVD ngā rauemi matua mō te hanga taputapu tapahi pēnei i ngā taputapu huri, ngā taputapu keri, ngā mata wiri, ngā riimere, ngā tapahi mira, ngā taputapu whakarārangi, me ngā mata kani. He mea nui te whiriwhiri i te rauemi taimana tika, ehara i te mea hei whakatutuki i ngā whakaritenga hangarau anake engari hei whakarite hoki i te oranga ōhanga me te pumau o te taiao.

He aha i whiriwhiri ai i ngā rauemi PCD me PCD/CC?

Ko te PCD me te PCD/CC ngā rauemi taimana matua i roto i te hanga hou, e mōhiotia ana mō ō rātou whakamahinga tino rerekē. Kāore ēnei rauemi e herea noa ki ngā mahi miihini tuku iho; e whakamahia whānuitia ana i roto i ngā ahumahi pēnei i te motuka, te rererangi, te tereina tere, te hinu, ngā matū, te hanga, me te mahi rakau. I roto i ngā rāngai motuka me te motopaika, he tino pai te PCD me te PCD/CC ki te miihini i ngā wāhanga kakahu-rahi, tae atu ki ngā papa piston koranu konumohe, ngā kōhao pine, ngā poraka rango, ngā pouaka miihini, me ngā carburetor. Ko te tikanga, he konumohe matrix composites kei roto i ēnei wāhanga he nui te ihirangi silicon (Si > 12%), ā, he nui ngā wero kakahu mō ngā matūriki uaua (pēnei i te SiC). Ka raru ngā taputapu carbide tuku iho ki ēnei rauemi uaua, ka poto te ora o te taputapu, ka piki ake ngā utu whakaputa.

Mahi Tino Pai me te Ngā Utauta Pcd

Mā te whakamahi i ngā taputapu PCD (PCD/CC rānei) hei miihini i te muka waro me ngā kirihou whakakaha muka karāhe (FRP) ka puta he painga whakamiharo: ka whakaitihia ngā maramara hei paura, ka noho iti te pāmahana tapahi, ā, he tekau ngā wā whakamiharo te roa o te tapahi i ngā taputapu karāhe karaehe K-class tuku iho, me ngā reiti pakaru iti iho i te hautoru o ngā taputapu karāhe. He pai hoki ngā taputapu PCD mō te miihini i ngā koranu mārō kua oti te whakakoi me ngā rauemi ātete-kakara kore-whakarewa pērā i te uku, te rapa, te karāhe, te karāhe, me ngā rakau pakari.

Ka pāngia te mahi a ngā taputapu PCD e tō rātou whakamahinga me te tukanga miihini motuhake. He mea nui te whiriwhiri i te momo me te rahi matūriki e tika ana mō ngā hua tino pai. He whānuitanga ngā taputapu a Boreas Ngā Mata Pcd, tae atu ki a LTM2200, LTM004, LTM10, me LTM90, me te rahi toharite o te kōhao he 1μm (angiangi), 4μm/10μm (waenganui), me te 25μm (mātotoru). Mā ngā rahi kōhao nui ake ka whakarei ake i te ātete ki te kakahu me te whakaroa i te roa o te ora o te taputapu, engari ka arahi pea ki te mata tapahi taratara. He maha ngā whakamahinga o ngā kōhao waenga mō te miihini whānui, ko ngā taputapu kōhao angiangi ia he kounga mata pai rawa atu nā te iti o ō rātou radius taha.

Mā Boreas, ka taea e koe te tumanako ki ngā hangarau matatau me ngā otinga kua whakaritea kia rite ki ō hiahia miihini. Ka whakapai tonu mātou i ā mātou rauemi PCD, ka whakarato i ngā rahi witi mai i te 2-30μm, kia tino whiwhi koe i ngā taputapu tino pai mō ō tono. Kōwhiria a Boreas mō te kounga me te mahi tino pai i roto i ngā taputapu tapahi taimana, ā, kia piki ake ō pūkenga miihini ki ngā taumata hou!
