Te Herenga Tuturu a te Kāpia Ātete Ahi Nui i ngā Mea Katoa

 

I te ao o te hanga matatau, te hanga, me te rererangi, kua roa te rapu i tētahi piripiri whānui e taea te tu atu i ngā āhuatanga tino kino. He tino pai ngā piripiri tuku iho—epoxies, cyanoacrylates, polyurethanes—i roto i ngā mahi rerekē engari he ngoikore nui: te wera. I ngā pāmahana i waenga i te 150°C ki te 300°C, ka pirau ō rātou mekameka polymer waro, ka arahi ki te hinganga nui. Ko tēnei herenga he arai mō ngā auahatanga i roto i ngā mara e hiahia ana ki te kaha tino teitei me te ātete ahi kore e taea te whakataurite. Tomo ki te mea e kiia nei ko "Kāpia Super Fireproof," he momo piripiri matatau e kore e herea noa te tini o ngā rauemi kia mau tonu, engari e mahi ana i a ia e kata ana i te aroaro o te mura. Ka rukuhia e tēnei tuhinga te matū, te tikanga, me ngā tono hou o ēnei piripiri kore-waro me te ranu e tautuhi ana i te pumau.

Te wetewete i te "Kāpia Super Fireproof"Pūrākau: Mai i te Mea Ora ki te Mea Kore Ora"

Hei mārama ki te putanga hou, me mārama tuatahi ki te ngoikore o ngā piripiri tuku iho. Ko te kaha o te piripono i ahu mai i ngā pūmua waro mekameka roa. Ina werahia, ka pāngia ēnei mekameka e te pyrolysis—ka pakaru ki ngā ngota iti ake, ka memeha, ka mahue te waro, ka kore rawa rānei. He maha ngā wā ka tāpirihia te ātete ahi i roto i ngā pūnaha tuku iho, ka whakawhirinaki ki ngā mea aukati mura pērā i ngā hydrates, i ngā phosphates rānei e tuku ana i te wai, e hanga ana rānei i ngā waro tiaki. He rautaki whakaroa tēnei, ehara i te otinga mō te piripono pumau, pāmahana teitei.

Ka whakarērea, ka whakarerekētia rānei tēnei tauira rauropi e ngā "Pūrere Ātete Ahi Tino" pono. E rua ngā whānau matū e hangai ana ki ēnei:

• Ngā Silicates me ngā Phosphates Kore-waro:Ko te poutokomanawa o ngā piripiri pāmahana teitei tawhito. Ka hanga hononga pakari, rite ki te uku te konutai, te pāhare pākawa, me ngā silicates konumohe (karaehe wai) ina maroke, ina whakapakeketia. Kāore e mura, ka tu atu ki ngā pāmahana neke atu i te 1000°C. Heoi, he maha ngā wā he pakarukaru, ā, he ngoikore te ātete ki te wai me te ru wera.
• Ngā Pūmua Waro-Kore Waro Ranu (Ngā Hiraka me ngā Kaiwhakakī):Koinei te wāhi e puta mai ai te mahi "tino pai" o ēnei rā. Ko te matū silicone te mea nui, inā koa ko ngā Polymer-Derived Ceramics (PDCs) me ngā kapia ranu silicone-based.

Ko ngā whakatakotoranga tino matatau ko ngā ranunga silicone me ngā whakakī whakakoi. I te pāmahana rūma, ka rite rātou ki te piripiri silicone pakari, ngāwari, kaha hoki, ka taea te hono i ngā konganuku, te karāhe, ngā uku, me te maha o ngā kirihou. Ka kitea tō rātou mana makutu i te wā e pāngia ana e te ahi.

 

 

Ngā Tikanga Matū o te Herenga Tuturu, Ātete Ahi

E rua ngā wāhanga o te here pumau o te kāpia ātete ahi: te Whakaora Āhuarangi me te Whakawhitinga Whakahohe-Wera.

Wāhanga 1: Te Whakaora me te Piripiri Āhua
Ka hangaia te piripiri hei whakapiri, hei kapia wai rānei. Ka whakamaroke i te pāmahana rūma mā te tauhohenga haukū, mā te tāpiri rānei, ka hanga he elastomer silicone pakari, he matrix kapia rānei. He pakari ake te pāmahana o tēnei matrix i ngā polymer waro, me te kaha wehenga hononga Si-O tata ki te 444 kJ/mol, versus ~347 kJ/mol mō te hononga CC.

Kei roto i tēnei matihiko e toru ngā wāhanga matua:

1. Te Whatunga Pūmua Hiraka:Ka whakarato i te ngāwari tuatahi, te piri, me te hiri taiao.
2. Ngā Whakakī Whakakī:Ngā kohuke pērā i te muscovite mica, te wollastonite, te glass frits rānei. Ehara ēnei i te mea koretake; kua rite te matū mō te hurihanga.
3. Whakakaha Whakakī:Ko ngā muka silica, muka waro rānei kua whakakāhia hei whakarato i te kaha ā-ringa tuatahi, hei tūāpapa hoki mō te wāhanga uku.

Ka tutuki te piri mā te whakakotahitanga o te raka ā-ringa ki ngā mata moroiti me te piri matū mā roto i ngā kaihoko hononga silane. Ko ēnei kaihoko, me ngā rōpū alkoxy e herea ana ki ngā mata kore-waro (ngā waikura whakarewa, te karāhe) me ngā rōpū waro e whakauru ana ki roto i te hanganga silicone, ka hanga i ngā piriti covalent i waenga i te papa me te piripiri.

 

Wāhanga 2: Te Tukanga Whakakī (Te Merekara Ārai Ahi)
Ina pāngia e te wera nui (>500°C), ka puta he raupapa matatau, tiaki-ā-iwi:

1. Te Whakawehenga me te Whakapūtanga:Ka tīmata te waikura o ngā wāhanga rauropi o te polymer silicone. Heoi, kaua e mimiti noa, ka waiho he āputa, engari ka waiho he silica hou (SiO₂). I te wā kotahi, ka tīmata te rere me te whakawera o ngā whakakī whakakī (hei tauira, te mika).
2. Te Hanganga Āhua Wai me te Whakakī Pore:I ngā pāmahana teitei motuhake, ka hangaia e ngā whakakī me te silica hou he āhua wai matotoru poto. Ka rere tēnei wai ki roto i ngā pūwero me ngā āputa i mahue i te polymer pirau, ka ārai i te hanganga o ngā kapiti.
3. Te Hanganga Here Uku:I te piki haere tonu o te pāmahana, i te pumau tonu rānei, ka whakamatao, ka totoka tēnei wāhanga wai hei uku mārō, piripono, ā, he mea kore-ora katoa, he uku karāhe-uku rānei. He mea hanga tēnei rauemi hou o ngā aluminosilicates, ngā silicates konupūmā, me te silica.
4. Te Haere Tonu o te Hononga:He mea nui, ka hangaia e tēnei uku kei roto, e hono tika ana ki ngā mata o te papa. Mā ngā matū honohono ka taea te whakawhiti mai i te hononga polymer-ki-papa ki te hononga uku-ki-papa. Mā ngā muka whakakaha (pēnei i ngā muka waro, ka waikura pea engari ka waiho he mahara hanganga, ngā muka uku rānei) ka pupuri i te pumau o te paparanga hononga, ka ārai i te mimiti me te pakaru.

Ehara te hua i te piripiri e noho ora te ahi; he piripiri e huri ana i te wā o te ahi mai i te pūmua ngāwari ki te whakarewa uku pakari, e mau ana i te kawenga. Ko te hononga, he mea tūturu, he wahi o te rauemi kua hanumi, ātete ahi.

 

 

Te Hanga i te Taonga "Here i tetahi Mea"

Ko te kereme "hononga i tetahi mea" e whakawhirinaki ana ki te pūtaiao mata me te whānuitanga o te hanganga. He rerekē ngā wero o ngā rauemi rerekē:

• Ngā konganuku (Rino, Konumohe, Parahi):He nui te kaha o te mata o ngā konganuku, ā, he maha ngā wā he paparanga waikura taketake tō rātou. He mea hanga ngā kaihoko hononga silane hei hanga hononga Si-O-Metara kaha. Me whakahaere hoki e te piripiri te koretake o te horapa wera; ka taea e te ngāwari o te silicones i mua i te whakakoi te whakauru i tēnei taumahatanga.
• Karaehe me nga Keraa:Ka piri tata tonu ēnei rauemi e ahu mai ana i te silica ki te hanganga silicone. Ko te wero he horoi me te whakatutuki i tētahi atanga kore hapa.
• Kirihou me te Hiato:He maha ngā kirihou hangarau (PEEK, phenolics, ētahi epoxies) ka taea te hono, inā koa mēnā ka tukatukahia ki te mata (hei tauira, te maimoatanga plasma) hei whakanui ake i te kaha o te mata. Me iti ake te modulus o te piripiri i te kirihou hei whakahaere i ngā kukū ahotea.
• Konukura me te Kōhatu:Me uru te piripiri ki roto i te hanganga moroiti porous. Ko ngā whakatakotoranga me te matotoru kua whakahaeretia me ngā silanes hydrophilic ka tutuki ai te hononga miihini hohonu me te hononga matū ki ngā mata silicate.

Ka tutuki i te "kapi nui" tēnei whānuitanga o te hangarau mā te noho hei hangarau tūāpapa. Ka whakarerekētia te pūnaha whakakoi-silicone turanga ki ngā momo kaihoko hononga silane, ngā whakarerekētanga rheology, me ngā kete whakakorikori hei hanga hua kua whakaritea mō ngā whānau papa motuhake.
