He rauemi tino nui te piripiri pakitara ārai mō ngā kaupapa hanga, ā, e whakamahia ana i roto i te hanganga pakitara ārai o te whare katoa, e taea te kī ko te "painga kore e kitea". He kaha teitei te piripiri pakitara ārai, he ātete ki te kiri, he ātete ki te pānga, he ngāwari te tukanga hanga, ā, he whānuitia te whakamahinga i roto i te hanganga me te tāutanga, te whakapaipai, te hiri, te hononga hanganga me ētahi atu mara. Ko te ahunga whanaketanga o te hoahoanga hou ko te hoahoa (te paerewa, te miihini hanga, te hanga i mua i ngā wāhanga me te taumaha mama, te kaha teitei me ngā rauemi hanga maha-mahi). Ā, he whānuitia te whakamahinga o te piripiri kaupapa pakitara ārai, ka tere ake te tukanga o ēnei e whā, ā, i roto i te whakapai ake i te tere hanga, te whakapaipai i te whare, te whakapai ake i te kounga o te hanganga, te penapena wā me te kaha, te whakaiti i te parahanga me te maha atu o ngā āhuatanga he mea nui, nō reira kua riro te piripiri pakitara ārai hei tētahi o ngā rauemi hanga matū nui. He aha ngā raruraru noa e pā ana ki te hanganga o te piripiri hangarau pakitara ārai he mahi nui? Me pēhea tā tātou whakatau i a rātou?
1. I roto i tēhea āhuatanga e hiahiatia ana he taunakitanga a te tohunga mō te piripiri hanganga kaha teitei?
I roto i te pakitara arai karāhe me te hoahoa hiri silicone hanganga tino matatau, me whakamahi ngā kaupapa pakitara arai i te hiri silicone hanganga tino-teitei waitohu Junbond hei whakapai ake i te uara f1 (uara hoahoa kaha hiri silicone hanganga i raro i te kawenga hau, rū whenua rānei), te uara f2 (uara hoahoa kaha hiri silicone hanganga i raro i te kawenga pumau), te uara δ (te kaha kawe nekehanga hiri silicone hanganga, hei whakaoti rapanga i te tukanga hoahoa. Ko te whānui, te matotoru rānei o te hoahoa hiri silicone hanganga i kitea he nui ake i te uara whakatakotoranga. Ko te whaihua o tēnei hoahoa tino matatau, ko te hiahia mō te aronga ki te kaupapa kei roto i te tari whare me te hanga tāone-tuawhenua ki te tono, ki te tari whare me te hanga tāone-tuawhenua ki te whakarite wā ki te whakatū i tētahi rōpū tohunga, hei manatoko tohunga.
2. He aha ngā pānga o te rumakina roa o te piripiri hanganga me te piripiri ātete-huarere? Kia pēhea te roa o te pānga ki te mahi o te rumakina?
Ko ngā piripiri hanganga me ngā piripiri ā-huarere he hiri silicone (nā te hanganga ngota o ngā hiri silicone anō, ka roa te wā e rumakina ana ki te wai, ka pakaru ētahi hononga matū, ka kore e piri. I roto i te paerewa GB16776 "hiri hanganga silicone hanga", me whakamātautau te piri hanganga silicone kia ora, me rumakina mō ngā rā 14, kia pai tonu te piri. I roto i te paerewa Amerika ASTM 1184, me whakamātautau te hiri hanganga ki te wai UV mō ngā hāora 5000, ka taea e te piripiri hanganga waitohu junbond te paahi i te whakamātautau me te kore raruraru. Heoi, i runga i te hoahoa o ngā momo whakatakotoranga o ngā piripiri silicone, tera pea ka rumakina ki te wai mō ngā marama maha ki ngā tau maha, ka pā ki te mahi. I roto i ngā take hangarau tūturu, kāore te hiri silicone e pai mō te rumakina roa ki te taiao, pērā i ngā ika moana me ētahi atu hononga i raro i te wai.
3. Ka taea e te piripiri hanganga o te karāhe te mahi hiri ā-wai?
Ka taea e te piripiri hanganga o te karāhe te mahi i tētahi mahi hiri ā-wai. Heoi, kāore e taea e te hoahoa o te pakitara ārai te whakatutuki i ngā whakaritenga hiri ā-wai, me whakawhirinaki rānei ki te hiri ā-huarere o waho hei whakatutuki i ngā whakaritenga hiri, ā, ka pāngia hoki te piri hanganga mō te wā roa ki te wai tōna hononga, ka whakaiti i te haumaru o te pakitara ārai. Mena ka whakamahia te piripiri hanganga hei hiri ā-huarere, tērā pea kāore e taea e tōna kaha neke te whakatutuki i ngā whakaritenga o te nekehanga hononga pakitara ārai, kāore te roa o te hiri i te pai ki te hiri ā-huarere motuhake.
