Ngā Whakamahinga Maha o te Paura Alumina i roto i te Ahumahi Aunoa
Tomo ki roto i tētahi waka hou, ā, ka kitea e koepaura konumohe e mahi puku ana i ngā mahi maha, engari he onge te kitenga a ngā kaihoko. I tēnei rā, kia hiki ake te taupoki, kia kite ai tātou me pēhea te whai wāhi nui o tēnei paura mā ki te nekehanga "tinana katoa" o te motuka.
Ⅰ. Ngā "Wheua Mārō" o ngā Papa Pēki
"He ngoikore ngā paraikete? Kāore pea i te tino pakari te rauemi waku!" te tangi a tētahi tohunga hangarau i tētahi wheketere papa paraikete i a ia e whakamātautau ana i ngā paraikete. He mea whakamiharo tōna kaha: mā te tāpiri noa i te 3%-5% ki te rauemi waku ka tino whakanui ake i te pakeke o te mata o te papa paraikete. He rite ki tētahi paparanga moroiti o te pukupuku, e ārai ana i a ia kei huri, kei pakaru rānei i raro i te waku pāmahana teitei. E whakaatu ana ngā raraunga mai i Hangzhou Jikang New Materials mā te tāpiri i tēnei tāpiri ka whakapai ake i te ātete ki te kakahu o te papa paraikete mā te neke atu i te 15%, ka waiho hei taputapu penapena utu mō ngā tekesi me ngā tīmatanga me ngā tūnga maha.
He pai ake tōna pakari – te waikura waikawa me te kawakore? Kāore he raruraru! 800°C te pāmahana? Ahakoa te kaha! Ka taea te whakatau i ngā raruraru waikura me te haruru o ngā papa parai whakarewa tuku iho mā te whakamahi i te tauira uku whakarei ake i te nano-alumina.
II. "Whare Honikoma" mō te Whakamaarama i te Hau Puta
I tētahi wheketere whakarewa matū i Beijing, ka pania e ngā kaimahi he paraoa kirimi ki tētahi kaikawe uku āhua honikoma. Ko te uho o tēnei paraoa he āhua-kama. nano-alumina, me te horahanga mata o te 130-200 m²/g. Ko te tikanga o tēnei, kotahi karamu o tēnei rauemi, e horahia ana ki te haurua o te rahi o te papa poitūkohu, he rite ki te toru ngā wā o te rahi.
Ina pā te hauhautanga o ngā waka mā roto i ēnei paninga nano, ka piri pūmau te hauota waro me te hauota waikura ki ngā mata o ngā pūwero o te alumina. Kātahi ka mahi ngā whakakorikori konganuku utu nui, ka hurihia hei hau kino. I whakamahia e tētahi tohunga hangarau i Jingcheng New Materials tētahi kupu whakarite: "He rite te Alumina ki te tūāpapa o tētahi whare, e āhei ai te konupūmā me te palladium, ngā 'VIP', ki te noho pūmau me te mahi kaha ake!"
Kua whakaatuhia e ngā whakamātautau ko ngā whakakorikori e whakamahi ana i te 10-30nmkonumohe whakanui ake i te ngohe pāmahana iti mā te tata ki te 20%—arā, he tere te purenga o te hauhautanga ahakoa i ngā tīmatanga makariri, he mea nui hei whakatutuki i ngā paerewa tukunga VIb pakari o Haina.
III. "Papa Whakamatao" mō ngā Kete Pūhiko
He aha te mea e tino wehingia ana e ngā kaipupuri waka hiko hou? Te wera rawa o te pākahiko! I whakaatu tetahi miihini i Hangzhou Jiupeng New Materials i tētahi ngongo tiēre kawe wera rite ki te paraihe niho: "Kei te kite koe i taua kanapa hiriwa? 60% o taua mea he alumina porohita!" Ko te paura kawe wera alumina CY-L15S he "wāhi whakamatao" mō te pūtau pākahiko.
Ko te kawe wera o te hinu silicone tuku iho he 1.5W/mK anake, ko te hinu tiēre kua whakakiia ki te alumina ka eke ki runga ake i te 6W/mK. I whakaatuhia e ngā whakamātautau i runga i te kete pākahiko mai i CATL ko te tāpiri i te paparanga kawe wera alumina ka whakaiti i te rerekētanga pāmahana i roto i ngā pūtau pākahiko i te wā e utu tere ana mai i te 15°C ki roto i te 5°C—ko te iti o te rerekētanga pāmahana, ko te roa ake o te ora o te pākahiko.
Ko te mahere whānui a Tianma New Materials e whakaū ana i te pikinga o te tono: kua tīmatahia he kaupapa hei whakaputa i te 5,000 tana o te paura alumina kawe-wera nui i ia tau, e aro ana ki te mākete whakamatao mō ngā pūnaha hiko-toru o ngā waka pūngao hou.
IV. "Tangata Whakakaha" Mama
"Ko te whakaiti i te taumaha me te kore e whakaiti i te kaha" te mea nui ki te whakamama i ngā waka. I roto i te rūma tauira o Shanghai Gaoquan Chemical, ka whakauruhia he paura iti alumina α-phase 80-160 ine ki roto i te kapia epoxy: "Mā te tāpiri ka taea te whakaiti i te matotoru o te pakitara o te whāriki parepare mā te 0.5mm, me te whakanui ake i tōna kaha!"
He rite te kaupapa ki te raima whakapakari:ngā matūriki aluminaka hangaia he "angaanga moroiti" i roto i te kirihou. E whakaatu ana ngā raraunga mai i tētahi kaihanga waka mā te tāpiri i te 30% alumina ki te rauemi polyamide i roto i te taupoki miihini ka piki ake te pāmahana whakarerekētanga wera mai i te 160°C ki te 290°C—he mea whakaora ora mō ngā wāhanga e tata ana ki te turbocharger.
He pai ake te utu: he rite te utu o te muka waro whakakaha ki te koura, engari ko te hautoru noa iho te utu mō ngā mea whakahiato alumina.
V. Pūhiko Mura "Pūkahu Ātete"
Wetewetehia te mono mura o te miihini, ā, ka kite koe i te kanapa kanapa o te paura iti alumina pāmahana-tiketike i runga i te ārai uku. E whakaatu ana tētahi pūrongo whakamātautau mai i te Shanghai Gaoquan Chemical Industry ka taea e te tinana uku, he mea tito mai i te 96% o te alumina α-phase, te tu atu i ngā pahūtanga ohorere i te 1700°C.
"I whakamahia e mātou ngā uku noa i mua, ā, ka pakaru, ka turuturu i muri i te 80,000 kiromita." I pupuri te miihini matua o tētahi wheketere mura i tētahi mea hou kua whakawhanakehiauku konumohe tinana, ā, ka mea, "Inaianei, i muri i te 150,000 kiromita, ahakoa ka wera ngā irahiko, ka noho tonu te uku!" Nā te āhua "pakari" o te alumina tēnei—kāore e ngokingoki i ngā pāmahana tiketike, ā, he iti te tauwehenga whānui wera, ka waiho hei turanga pakari i roto i te "Maunga Mura" o te rango.
VI. He "Tohu Hou" mō te Papa Pakanga o te Ao
Kei te haere tonu te auahatanga o te alumina. Kua waiho kētia te tohu o te alumina kua whakarerekētia ki te whenua onge i roto i te taiwhanga: ka whakapai ake ngā papa parai e whakauru ana i ngā iti o te yttrium oxide i te ātete ki te kakahu mā te 10%, ā, ka roa ake te roa o te ora o ngā paninga whakakorikori kua whakareihia ki te cerium oxide mā te 30%.
Ko ngā tono hou ake kei roto i te taraiwa atamai—ko ngā karāhe radar mirimita-ngaru e hiahia ana ki ngā rauemi e tuku ana i te ngaru me te whakamarara wera. Kei te whakamātautau tētahi kamupene Hangzhou i tētahi rauemi hiato alumina/silicone: kei te pumau tonu tōna pūmau dielectric i te 3.2, ā, e rima ngā wā e kawe ana tōna wera i te kirihou tuku iho, e āhei ai te radar ki te "kite" tika i te rori ahakoa te pāmahana o te 120°C.
Mai i ngā waka hinu tuku iho ki ngā waka hiko atamai, ko te mekameka uara opaura konumohekei te whānui haere tonu. Kāore pea e puta i roto i ngā pukapuka waka, engari ina pupuri tātou i te urungi, ka tiakina pukutia ia parai haumaru, ia tuku hiko whai hua, me ia manawa ma e tēnei paura mā, e huna ana i te tirohanga.
Ā, i te putanga mai o ngā papa pakanga hou pērā i ngā papa whakamahana pākahiko totoka me ngā pereti aratohu puranga pūtau wahie hauwai, kei te whānui haere tonu te ara o te alumina ki te noho hei "toa huna".
