He Aratohu ki ngā Rīpene Intumescent

He rauemi motuhake ngā rīpene intumescent e whakamahia whānuitia ana i roto i ngā pūnaha tiaki ahi, inā koa i roto i ngā tatau me ngā matapihi, hei āwhina i te pupuri, i te whakawhāiti rānei i te horapa o te ahi. Ina pāngia e te wera, ka whānui ēnei rīpene (intumesce) hei hiri i ngā āputa, hei ārai i te haere o te paoa, te wera, me ngā mura. Anei tētahi aratohu whānui hei mārama ki ngā rīpene intumescent, ō rātou kaupapa, me te whakamahinga.

1. He aha ngā Rīpene Intumescent?

Ko ngā rīpene intumescent he mea hanga mai i te huinga o ngā matū me ngā kapia e tauhohe ana ki ngā pāmahana teitei. He maha ngā wā ka whakauruhia ki roto i ngā anga tatau, ngā anga matapihi, me ētahi atu whakatuwheratanga hei tikanga tiaki ahi kore mahi. Ina pāngia e te wera, e ngā mura rānei (i runga ake i te 200°C, 392°F rānei), ka whānui te rauemi, ka whakakī i ngā āputa me te hiri i ngā wāhi e āhei ai te ahi, te paowa rānei kia puta.

2. He pēhea te mahi a ngā rīpene Intumescent?

Ko te mahi matua o ngā rīpene intumescent he mahi hei ārai ahi mā te pupuhi ina pāngia e te wera. Ko te whānui o te rahi he maha ngā wā i te rahi taketake, ka hanga he mura matotoru e tino ātete ana ki te ahi. Mā tēnei mahi hiri ka ārai i te haere o te paoa, te wera, me ngā hau paitini, ka whakapai ake i te ātete ahi o ngā tatau, matapihi, me ētahi atu whakatuwheratanga.

Ngā mahi matua o te tukanga:

• Te Whakamārama WeraIna tae te pāmahana huri noa i te rīpene ki tētahi taumata tino nui, neke atu i te 200°C (392°F), ka tīmata te whānui o te rīpene.
• WhanuitangaKa tīmata ngā rauemi i roto i te rīpene, kei roto nei he ranunga o te karāpeti, te ammonium phosphate rānei, ki te tauhohe matū, ka whakawhanui te rīpene.
• Te Hiri i ngā ĀputaI te pupuhi o te rīpene, ka hiritia rawatia ngā taha o ngā tatau, o ngā matapihi rānei, kia kore ai e horapa te ahi, te paoa rānei mā te whakatuwheratanga.

3. Ngā Whakamahinga o ngā Rīpene Intumescent

He maha ngā whakamahinga o ngā rīpene intumescent, ā, e whakamahia ana i roto i ngā momo mahi hei whakarei ake i te ārai ahi:

• Ngā Kūaha AhiKo tētahi o ngā whakamahinga tino noa, ko te wāhi e whakanohoia ai ngā rīpene intumescent ki ngā taha o ngā tatau ahi hei hiri pūmau ina pāngia e te wera. Ka āwhina tēnei ki te ārai i te paoa me te mura kei neke haere i waenga i ngā rūma mēnā ka puta he ahi.
• MatapihiI ngā matapihi ahi, ka whakamahia ngā rīpene intumescent huri noa i te anga hei aukati i te whakawhiti wera me te paowa.
• Ngā awa whakapūhauKa whakamahia ngā rīpene hei ārai i te ahi i roto i te rūma, kia kore ai e horapa mā roto i ngā pūnaha tohanga hau.
• Ngā Katinga Ahi-WhakatauhiaE whakamahia ana hoki ēnei i roto i ngā katinga ahi-ātete, tae atu ki ngā pou ararewa, ngā taupoki, me ētahi atu urunga mā roto i ngā pakitara, i ngā tuanui rānei e ahi-ātete ana.

4. Ngā Momo Rīpene Intumescent

He maha ngā āhua o ngā rīpene intumescent i runga i te rauemi, te hoahoa, me ngā hiahia tono. Ko ngā momo noa ko:

• Ngā Rīpene MārōHe here totoka, he rīpene rānei ēnei o te rauemi intumescent māmā, ka whakaurua ki roto i ngā āputa huri noa i ngā tatau, i ngā matapihi rānei.
• Ngā Rīpene PahukaKo ētahi rīpene intumescent he mea hanga hei rauemi pahuka, ka nui ake te whakawhanui, ka hanga he hiri nui ake.
• Ngā Pakitara Kua HangaiaHe rīpene ēnei kua oti te hanga ki ngā āhua me ngā rahi motuhake mō ngā momo tatau, ngā anga rānei.

Ka taea hoki te hanga i ēnei i ngā rahi rerekē, i runga i ngā whakaritenga o te tatau, o te anga rānei me te taumata o te ārai ahi e hiahiatia ana.

5. Ngā Whakatauranga me ngā Paerewa Mahi

Ka whakamatautauria ngā rīpene intumescent ki te ahi, ā, me tutuki i ngā paerewa haumaru ahi ā-motu me te ao. Ko ētahi o ngā paerewa e whakamahia whānuitia ana ko:

• BS 476-22Ko te paerewa Piritana mō te ātete ahi o ngā wāhanga kāore e mau kawenga, pērā i ngā tatau me ngā matapihi.
• EN 1634-1He paerewa Pākehā mō te whakamātautau ātete ahi o ngā tatau me ngā huinga kati.
• NFPA 252He paerewa mai i te National Fire Protection Association (NFPA) i te US mō ngā whakamātautau ahi o ngā huihuinga tatau.
• UL 10CKo te paerewa a te Underwriters Laboratories mō ngā tatau ahi-whakatau i te Hononga o Amerika.

Mā ēnei paerewa e whakatau te roa o te wā e taea ai e te tatau, e te matapihi rānei te tu atu ki te ahi i mua i tōna pakaru. Ko te kaha o te hiri piripono ki te hanga i tētahi hiri piripono he mea nui ki te whakapiki i tēnei whakatauranga ahi.

6. Te Tāutanga o ngā Rīpene Intumescent

He mea nui te tāutanga tika o ngā rīpene intumescent mō tōna whai huatanga. Ki te kore e tāuta tika, ka ngoikore te ātete ahi o ngā tatau me ngā matapihi.

Ngā whakaaro matua mō te tāutanga:

• Ngā Tapa o te KūahaKo ngā rīpene intumescent ka whakamahia i te nuinga o te wā ki ngā taha o ngā tatau ahi, ki te wāhi e tūtaki ai ki te anga o te tatau. Ka taea te whakauru ki roto i ngā awaawa, ka whakamahia rānei ki te anga o te tatau.
• Ngā Anga MatapihiMō ngā matapihi, ka whakatakotoria ngā rīpene ki te taha o te anga, inā koa i ngā taha e tūtaki ai te karāhe ki te anga.
• Te Rahi TikaMe tika te rahi o ngā rīpene intumescent mō te āputa, te anga rānei e tika ana kia hiritia. Mēnā he nui rawa ngā āputa, ka raru pea te kaha o te rīpene ki te whānui me te hiri i te wāhi.
• Kapinga TuturuKia tino kapi katoa te taha o te whakatuwheratanga ki te rīpene intumescent, kia kore ai he āputa e taea ai e te paoa, e te mura rānei te puta.

7. Te Tiaki me te Tirotiro

Me tirotirohia ngā rīpene intumescent i ia wā, i ia wā, kia mōhio ai kāore i pakaru, i te memeha rānei. Kotahi noa te wā ka puta ai te kaha whakawhanui o ēnei rīpene, nō reira, ki te pakaru, ki te wera nui rānei, e kore e mahi tika i roto i tētahi ahi ā muri ake nei.

Ngā tohutohu tiaki matua:

• Ngā Tirotiro TirohangaTirohia mēnā he ngatata, he haehae, he āputa rānei kei roto i ngā rīpene.
• Whakamātautau mō te Mahi TikaMena kāore te tatau, te matapihi rānei e hiri tika ana, me whakakapi pea ngā rīpene intumescent.
• Whakakapia ngā Rauemi Kua Pau: I roto i te wā, ka ngaro pea te whai huatanga o ngā rīpene intumescent. Me whakakapi tonu kia rite ki ngā taunakitanga a te kaihanga.

8. Ngā Painga o ngā Rīpene Intumescent

He maha ngā painga o ngā rīpene intumescent mō te haumaru ahi, tae atu ki:

• Te Ātete Ahi Whakapai AkeKa tino whakarei ake i te ātete ahi o ngā tatau, matapihi me ētahi atu whakatuwheratanga.
• Tāutanga MāmāHe ngāwari te tāuta i ngā rīpene intumescent maha, ā, ka taea te whakauru anō ki ngā tatau me ngā matapihi o nāianei.
• Te Pupuri AuahiHaunga te tiaki i te wera me te mura, ka āwhina ēnei rīpene ki te pupuri i te paoa, he rite tonu te morearea ki te ahi.
• Whai hua te utuHe huarahi utu-pai ēnei hei whakapai ake i te parenga ahi i roto i ngā whare, me te kore e nui ngā huringa hanganga.

9. Ngā Here

Ahakoa he tino whai hua ngā rīpene intumescent i roto i ngā āhuatanga ahi maha, he iti noa iho ō rātou ngoikoretanga:

• Whakamahinga KotahiKotahi noa te mahi a ngā rīpene ina wera. I muri i te ahi, me whakakapi.
• Kāore e tika ana mō ngā whakatuwheratanga katoaHe mea whakamahi noa ēnei mō ngā pūaha iti pēnei i ngā tatau me ngā matapihi, engari kāore pea e pai mō ngā pūaha nui ake, mō ngā wāhi rānei e hiahiatia ana he ārai ahi kaha ake.
• He iti noa iho nā te hoahoaKo te whai huatanga o te rīpene intumescent e whakawhirinaki ana ki te tāutanga tika me te hototahi ki ngā rauemi e karapoti ana.

Whakamutunga

He tikanga māmā engari he tino whai hua ngā rīpene whakapūmau hei whakarei ake i te haumaru ahi i roto i ngā whare. Ina tāuta tika, ka whakarato i tētahi ārai nui ki te paoa, te wera, me te horapa o te ahi, ā, ka āwhina ki te tiaki i ngā kainoho me te whakaiti i te kino o ngā rawa i te wā o te ahi. He mea nui te tirotiro me te tiaki auau kia pai ai te mahi ina hiahiatia.

Mena kei te mahi koe i te haumaru ahi, i te hanga whare rānei, he mea nui kia whiriwhiria te momo rīpene intumescent tika mō tō tono, kia tutuki ai hoki ngā paerewa e tika ana mō tō rohe, mō tō ahumahi rānei.
