Ngā Hua Kakahu Kore-Whatu Polyimide

I. Ngā Āhuatanga Matua o te Kakahu Kore-Whatu Polyimide: Te Kaimahi Katoa i roto i ngā Taiao Tino Kino

Mā te whakamahi i ngā painga ā-roto o te rauemi PI me ngā āhuatanga ahurei o te tukanga hydroentanglement, e toru ngā āhuatanga matua o te papanga polyimide kore-whatu e wikitoria ana i ngā herenga mahi o ngā muka waro me ngā muka kore-waro tuku iho i roto i ngā āhuatanga pāmahana teitei, ātete-mura, ātete-huarere, me te whakauru mahi:

1. Te Pūmautanga o te Pāmahana Teitei + Te Ārai i te Mura o Roto: He Ārai Haumaru mō ngā Taiao Mōrearea Teitei

He ātete wera nui atu i ngā rauemi tuku iho: Kāore i rite ki te aramid (pāmahana ratonga roa: 204°C) me te PTFE (pāmahana ratonga roa: 260°C), ka mau tonu te hanganga o te polyimide i raro i te mahi tonu i te 260°C, me te manawanui poto tae atu ki te 400°C. Kāore e pakaru te hanganga muka wai-raruraru, kāore e whakaatu i ngā tohu o te koroheketanga, te hekenga rānei i muri i te neke atu i te 1.5 tau o te whakamahinga tonu i roto i ngā tono pēnei i te tahunga para me ngā taiao pāmahana teitei whakarewa, ka hua ake he roa ake te ora ratonga i te toru ngā wā i ngā rauemi aramid.

Te ātete mura tino pai: Me te kore e hiahiatia he tāpiringa ātete mura, ka tutuki i te rauemi he taupū hāora whakawhāiti (LOI) o te 38% (he nui ake i te PTFE 28% me te aramid 29%). Kāore e mura, e rewa rānei ina pāngia e te mura, ka tineia tonutia ina tangohia te mura, ā, kāore e tukuna he hau paitini i te wā e tahuna ana. Mā tēnei ka ārai i te horapa o te mura, ka whakatika i ngā ngoikoretanga nui o ngā rauemi ātete mura tuku iho pērā i ngā whara i puta mai i te rewa me te tukunga paitini o te auahi.

2. Ātete Whānui ki te Huarere + Pūmautanga Mīhini: He Pūkahu Pakari mō ngā Āhuatanga Kino

Te ātete tino pai ki te waikura me te koroheketanga: He tino pai te ātete o te papanga ki te nuinga o ngā rauemi waikawa-pūtake (hei tauira, 10% waikawa whanariki, 15% hauwai konutai), ngā whakarewa waro, me te hihi UV, me te ngaronga kaha kume o te ≤8% i muri i te 60 rā o te rumaki. Kāore e whakaatu i te pakarukaru, te pirau rānei i raro i te pānga roa ki te UV o waho, te haumākū, me te wera, ka eke ki te roanga mahi o te 8–10 tau i roto i te mana karihi me ngā tono hangarau o waho—neke atu i te 10 ngā wā i ngā rauemi polyester tuku iho.

Ngā āhuatanga miihini tino pai: Me te matotoru o te muka o te 1.41 g/cm³ me te kaha pakaru roa o te 600 N/5×20 cm, e 20 ngā wā te kaha o te papanga polypropylene i te taumaha kotahi. I muri i te hononga wai, ka eke te ātete haehae ki te ≥50 N, me te pupuri i te kaha makuku 100%. Ka hinga tēnei i te pakarukaru pāmahana iti o ngā muka basalt me ​​te kore e ranea te kaha miihini o te PTFE, e pai ai mō ngā tono taumaha me te ahotea hihiri.

3. Hototahi Mahi + Tukatuka Ngāwari: He Pūtake Whānui mō te Whakaritenga

Mā te whakamahi i te hydroentanglement ka tiakina te mahi a te rauemi: Mā te tukanga spunlace pēhanga teitei ka āta honoa te muka, me te kore e pā kino ki te wero ngira. He ngohengohe te hua (pakeke ≤50 Shore A) me te pai o te here, e taea ai te tapahi tika, te tuitui, me te hanga wera. Mā tēnei ka whakatauhia ngā wero tukatuka o ngā ngira PI tuku iho, he pakari, he pakarukaru hoki, me te whakarato i te mata maeneene, kore-pūwero, he pai mō te whakaurunga wāhanga tika.

Te kaha nui mō te mahi: Mā te whakarerekētanga mata, mā ngā tikanga whakakotahi rānei, ka taea te whakawhiwhi i te papanga ki ngā mahi matatau maha. Hei tauira, i muri i te maimoatanga kawakore me te utaina ki ngā matūriki nano Fe₃O₄ me Ag, ka tutuki i a ia te whai huatanga tiaki hikohiko teitei (77 dB) me te whakaata tino iti (≤-10 dB). Ina honoa ki ngā muka nano, ka whakaatuhia e ia ngā āhuatanga tātari pāmahana teitei me te huakita, e tutuki ana i ngā whakaritenga rerekē i roto i te huna hōia me ngā tono hauora teitei.

II. Ngā Āpure Whakamahinga Matua o te Kakahu Kore-Whatu Polyimide: Ngā Otinga Kāore e Taea te Whakakapi mō ngā Horopaki Tino Pai

I runga i ngā āhuatanga o runga ake nei, kua noho te papanga kore-whatu polyimide hei rauemi nui i roto i te tātari pāmahana-tiketike, te tiaki motuhake, te hikohiko/hōia, me ngā mara hauora matatau, e whakatutuki ana i ngā tono mōrearea nui, tono nui, me te roa o te ora:

1. Te Tātari Mahana-Teitei me te Tiaki Taiao: Te Otinga Whakapaipai Matua mō ngā Mate Kino

Tātari hau paipa pāmahana-tiketike: Whakamahia ai i roto i ngā putea tātari mō ngā tipu tahu para me ngā tātari tango puehu i roto i ngā tipu hiko waro, ka hopukina e te papanga te puehu pai me ngā matūriki waikura i te 300°C, me te tika o te tātari o te 0.5 μm. Ko tōna LOI teitei (38%) ka ārai i ngā mōrearea tahunga i puta mai i te pāhare pāporo me te konutai i roto i te pungarehu rere, e tuku ana i te roanga ratonga neke atu i te rua o te roanga o te ora o ngā rauemi tātari PPS.

Tātari pāmahana teitei ā-ahumahi: Kei roto i ngā whakamahinga ko ngā kakahu tātari mō ngā tukunga o te teihana whakaranu uku me ngā putea tātari mō te tātari whakarewa pāmahana teitei i roto i ngā tipu matū. Ka ātete te papanga ki ngā pāmahana 260°C me te waikura whakarewa waro, kāore e mimiti i ngā wāhanga tātari, ka whakarite kia parakore te hua, ā, he pai ake te mahi ārai-aukati, ka whakaiti i te ātete tātari mā te 30% ki te whakataurite ki ngā tātari muka karāhe tuku iho.

2. Te Tiakitanga me te Haumaru Motuhake: He Arai Ora i roto i ngā Āhuatanga Mōrearea Nui

Taputapu tiaki whaiaro: Hei arai mō ngā kākahu ātete ahi whakarewa me te papanga mō ngā kākahu whakamahana a ngā kaipatu ahi, ka mau tonu te hanganga o te rauemi i te 260°C, me te kawe wera o te 0.03 W/(m·K) anake, e ārai pai ana i te irahiko pāmahana teitei. Ko tōna kakano ngawari, manawa hoki he nui ake te whakamarie i ngā rauemi huruhuru toka tuku iho, he mea tino pai mō ngā mahi pāmahana teitei i roto i te whakarewa me te tinei ahi.

Ngā hua tiaki ohorere: Kei roto i ngā tono ko te papanga tēneti ātete ahi hōia me ngā ārai ātete mura mō ngā wāhi morearea nui. Ko te rauemi ātete mura me te huarere kāore e pirau i raro i te haumākū o waho, te wera, te kaha rānei o te hihi UV, ā, he ārai pumau tonu. Nā tōna rahi piko kia tere te whakatakoto i roto i ngā āhuatanga ohorere, he pai mō te huna i ngā hōia me te urupare ki ngā aituā matū.

3. Ngā Mahi Hikohiko me te Hoia: Te Matua Mahi o ngā Taputapu Tino Pai

Ngā rauemi ārai hikohiko: E whakamahia ana i roto i ngā papanga huna radar me te whakakī ārai-whakararuraru mō ngā taputapu hiko, ka tutuki i te papanga te mimiti ngaru hikohiko pai puta noa i te awhe whānui 8.2–40 GHz i muri i te utaina o ngā matūriki aukume me te whakakikorua hiriwa kore-hiko, me te whai huatanga o te ārai tae atu ki te 77 dB. Ka mau tonu te mahi pumau i te 250°C, ka tiaki i ngā taputapu hōia mai i te whakararuraru hikohiko me te whakahohe i te huna infrared.

Ngā wāhanga ārai pāmahana teitei: Kei roto i ngā whakamahinga ko ngā arai ārai mō ngā miihini rererangi me te kakahu whakakī mō ngā wāhanga hiko kounga teitei. Me te kaha hiko-kore ≥25 kV/mm i te 260°C, ā, kāore he hekenga o te mahi ārai, ka ātete te papanga ki te waikura e ngā hinu me ngā wahie, ka ārai i ngā ara iahiko poto i roto i ngā wāhanga hiko, ā, ka tutuki i ngā hiahia o ngā ahumahi rererangi me ngā ahumahi motuka kounga teitei.

4. Ngā Kakahu Hauora me ngā Kakahu Tino Pai: Te Whakapūmau i te Haumaru me te Ma

Ngā hua tiaki hauora: Ka whakamahia i roto i ngā kākahu pokanga ka taea te whakahoro i te pāmahana teitei me ngā papa takai whakahoro, he tino hototahi te rauemi ki te koiora (kāore e pāwera, kāore e whakapataritari) ā, ka tu atu ki te 134°C te whakahoro mamaoa me te kore e maringi te muka, e tutuki ana i ngā paerewa whakahoro GMP. Ka whakarite i te haumaru mahi i roto i ngā āhuatanga hauora matatau pēnei i te whakawhitinga okana me te pokanga iti rawa te whakaekenga.

Ngā kakahu whai hua: Kei roto i ngā tono ko ngā hūtu ātete-mura mō ngā reihi me ngā kākahu tiaki mō te umanga karihi. Ko te papanga ātete-mura tuturu, he manawa-ā-ringa, he whakamarie hoki, kāore e puta he riri o te kiri i te wā e mau ana mō te wā roa. Ka ātete hoki ki te irahiko me te waikura matū, ka tiaki i ngā kaimahi mai i ngā wera me te pānga irahiko i roto i ngā wāhi motuhake pēnei i ngā hākinakina motuka me te tiaki hiko karihi.
