Ngā Pātai Auau (FAQ) – Takirere Porowhita Cryogenic (-196°C)
P: He aha te rerekētanga i waenga i te takirere porowhita cryogenic me te takirere porowhita paerewa?
A: He maha ngā āhuatanga matua o ngā takirere porowhita cryogenic kāore i kitea i roto i ngā takirere paerewa: he taupoki roa me te pereti maturuturu hei tiaki i ngā hiri kakau; he maimoatanga cryogenic hohonu o ngā wāhanga katoa; he rauemi nohoanga motuhake (PCTFE, PEEK) mō ngā pāmahana iti; he iti te tākai tukunga rerenga; me te whakamātautau mahi cryogenic whakahau i runga i te BS 6364.
Q: He aha te pāmahana ratonga iti rawa mō āu takirere porowhita cryogenic?
A: Ko ā mātou takirere porowhita cryogenic paerewa he mea whakatau mō te ratonga -196°C e ai ki te BS 6364. Mō te ratonga hauwai wai (-253°C) me te ratonga herium wai (-269°C), ka tukuna e mātou he hoahoa motuhake.
P: He aha te maimoatanga cryogenic hōhonu, ā, he aha i hiahiatia ai?
A: Ko te maimoatanga hohonu o te cryogenic he tukanga whakamatao i ngā wāhanga takirere ki te -196°C mō te iti rawa 8 hāora. Ka hurihia e tēnei te austenite e puritia ana, ka whakaiti i te ahotea toenga, ā, ka whakarite i te pumau o ngā āhuatanga i te pāmahana ratonga.
Q: He aha ngā rauemi nohoanga e taunaki ana koe mō te mahi i te pāmahana -196°C?
A: Mō te ratonga -196°C, ka tūtohu mātou i te PCTFE hei rauemi nohoanga matua. Ka mau tonu te PCTFE i ōna āhuatanga miihini, ā, ka whakarato i te hiri pai rawa atu i ngā pāmahana cryogenic.

Ngā Wero Hangarau me ngā Otinga:
1. Te whakahaere rere tika i te -196°C mō te parakore o te huaKo ngā whakaritenga parakore o te hua ASU (99.999% mō te taumata hikohiko) e hiahia ana kia tika te whakahaere rere. I tukuna mai e Womic ngā takirere porowhita me ngā nohoanga PCTFE me ngā kōpae mata mārō Stellite mō ngā āhuatanga whakatītaha pumau. I paahitia e ngā takirere 120 katoa te whakamātautau cryogenic me te kore turuturu.
2. Maimoatanga cryogenic hohonu mō ngā tinana CF3M whakarewaKo ngā tinana CF3M i whakarewahia he mea ngāwari ki te pupuri i te austenite. I whakahaerehia e Womic te maimoatanga cryogenic hohonu e toru-huringa (te rumaki ki te -196°C, 12 hāora ia huringa). I te tirotiro anō i ngā āhuatanga, kāore he hapa i whakaūtia.
3. He iti te tākai tukunga rerenga mō te ratonga hāoraMe tino horoi te ratonga hāora, ā, me iti hoki te tākai i ngā tukunga rere. I tukuna e Womic te tākai ISO 15848-1 Akomanga A me ngā hinu whakahinuhinu hototahi ki te hāora.
4. Tirotiro a te rōpū tuatoru e BVMe whai wāhi te kiritaki ki ngā whakamātautau a te Bureau Veritas. I tukuna e BV ngā tiwhikete i roto i ngā rā 10.
Hua:Kua oti te whakawhanui i te ASU te whakatū. Kua neke atu i te 18 marama te mahi a ngā takirere porowhita cryogenic 120 i te -196°C, kāore he aituā tiaki.
