Te Pānga o te Pāmahana ki te Ngāwari o ngā Papa Hiraka: He Tātaritanga me te Rangahau Whānui

I. Kupu Whakataki
Kua noho ngā papa hiku silicone hei hua noa i roto i te maha o ngā whare me ngā tari nā te mea he ngawari, he whakamarie, he pakari hoki ō rātou āhuatanga. Heoi, he pānga nui tō ngā huringa pāmahana ki te ngāwari o ngā papa hiku silicone. Mā te mārama ki ēnei pānga ka āwhina i ngā kaihoko ki te whiriwhiri me te whakamahi pai ake.ngā papa hiku silicone, engari e whakarato ana hoki i tētahi pūtake mō ngā kaihanga hei whakapai ake i te hoahoa hua. Ka matapakihia e tēnei tuhinga ngā āhuatanga o ngā rauemi silicone, te tikanga o te pānga o te pāmahana ki te ngāwari o te silicone, ngā hua rangahau whakamātautau, me ngā whakaaro tono mahi.

II. Ngā āhuatanga taketake o ngā rauemi silicone
(I) Te pumau wera o te silicone
He pūhui pūhui te silicone i hangaia mā te tauhohenga o te hauhā silicon (SiO₂) me te wai, ā, he pai te pumau o te wera. Ka taea e te silicone te pupuri i ōna āhuatanga ā-tinana me te matū i roto i te whānuitanga o te pāmahana (te nuinga o te wā -60°C ki te 250°C). Mā tēnei pumau wera ka taea e te silicone te pupuri i tōna ngāwari i roto i ngā momo taiao.
(II) Te ngāwari o te silicone
He pai te ngāwari me te ngāwari o te silicone, ā, ka taea e ia te hoki ki tōna āhua taketake ina huri te pēhanga. Mā tēnei āhuatanga ka taea e ngā papa papa silicone te tautoko pai i te wā e whakamahia ana. Heoi, ka pāngia te hanganga ngota o te silicone e ngā huringa o te pāmahana, ka pāngia hoki tōna ngāwari.

III. Te tikanga o te pānga o te pāmahana ki te ngāwari o te silicone

(I) Te pānga o te pāmahana teitei ki te ngāwari o te silicone

Ka tere ake te pakaru me te whakakotahitanga o ngā mekameka ngota silicone i te pāmahana teitei, ka heke te kaha ā-pūkaha o te rauemi. E whakaatu ana ngā whakamātautau, i te pikinga ake o te pāmahana, ka heke te modulus elastic o te silicone, ā, ka puta pea ngā kapiti ki te mata. Nā te mea ka tere ake te nekehanga wera o ngā mekameka ngota silicone i te pāmahana teitei, ka ngoikore te taunekeneke i waenga i ngā ngota, ā, ka whakaiti i te elasticity o te rauemi.

(II) Te pānga o te pāmahana iti ki te ngāwari o te silicone

Ka whakaitihia te pakari o te silicone i te pāmahana iti, ka iti ake te ngāwari o te rauemi. Nā te mea ka whakaitihia te nekenekehanga o ngā ngota silicone i te pāmahana iti, ā, ka whakarei ake i te taunekeneke i waenga i ngā ngota. I ngā pāmahana tino iti, ka taea e te silicone te tio, ka whakaitihia ake tōna pakari. Hei tauira, kua kitea e ngā rangahau i te pāmahana iti o te -55°C, ka nui ake te rerekētanga pumau o te silicone i te pēhanga, ka hua ake te pakaru o te rauemi.

(III) Te pānga o te huinga pāmahana me te haumākū ki te ngāwari o te silicone

Ina whakaarohia ngā pānga o te pāmahana me te haumākū i te wā kotahi, ko te taiao pāmahana teitei me te haumākū teitei te mea nui rawa atu ki te koroheketanga o te silicone. Ehara i te mea ka tere ake te tukanga koroheketanga wera o te silicone i tēnei taiao, engari ka whakanui ake hoki i te pānga koroheketanga wera mākū. E whakaatu ana ngā raraunga whakamātautau i raro i ngā āhuatanga pāmahana teitei me te haumākū teitei, ka taea te whakaiti i te kaha ā-pūkaha o te silicone i roto i te wā poto.

IV. Rangahau whakamātautau me te tātari
(I) Ngā tikanga whakamātautau
Hei ako i te pānga o te pāmahana ki te ngāwari o te silicone, i hangaia e ngā kairangahau he raupapa whakamātautau. Ko ngā rauemi whakamātautau i whakamahia he hua silicone arumoni, ā, i whakatauirahia te taiao whakamahinga tūturu mā te whakahaere i ngā āhuatanga whakamātautau. Ko ngā tawhā motuhake koia ēnei:
Awhe pāmahana: mai i te pāmahana rūma ki te 150°C
Awhe haumākū: mai i te 10% ki te 90% te haumākū whanaunga
Te wā pakeketanga: mai i te 1 rā ki te 365 rā
(II) Ngā hua o te whakamātautau
E whakaatu ana ngā hua o te whakamātautau he pānga nui tō te pāmahana teitei me te pāmahana iti ki te ngāwari o te silicone. I ngā pāmahana teitei, ka heke te kaha o te silicone, ā, ka puta pea ngā kapiti ki te mata. I ngā pāmahana iti, ka heke te pakari o te silicone, ā, ka pakarukaru te rauemi. Hei tāpiri, ka tere ake te tukanga koroheketanga o te silicone i ngā taiao pāmahana teitei me te haumākū teitei, ā, ka whakaitihia anō tōna ngāwari.
(III) Ngā whakatau whakamātautau
He mea nui te pānga o te pāmahana ki te ngāwari o te silicone. Ka whakaitihia e ngā pāmahana teitei te āhua ngāwari o te silicone, ā, ka whakaitihia e ngā pāmahana iti tōna pakari. I raro i ngā āhuatanga pāmahana tino kino, ka heke pea ngā āhuatanga ngāwari o te silicone, ka pā ki tōna roanga mahi.

V. Ngā whakaaro whaihua mō te whakamahinga
(I) Kōwhiria te rauemi silicone tika
Mō ngā papa papa silicone e hiahiatia ana kia whakamahia i ngā taiao pāmahana teitei, me whiriwhiri ngā rauemi silicone he nui ake te ātete ki te wera. Mō ngā hua silicone e whakamahia ana i ngā taiao pāmahana iti, me whiriwhiri ngā rauemi silicone he pai ake te mahi pāmahana iti.
(II) Te tirotiro me te tiaki i ia wā
Tirohia tonutia mēnā kua pakaru, kua hē rānei te mata o te papa o te papa silicone, ā, whakakapia ngā hua tawhito i te wā tika. Mēnā ka whakamahia i roto i ngā taiao pāmahana teitei me te haumākū teitei, me mahi ngā mahi tiaki tika, pērā i te paninga ātete-makuku.
(III) Te whakamahinga whaitake
Kaua e whakamahi i ngā papa silicone mō te wā roa i raro i ngā āhuatanga pāmahana tino kino. Hei tauira, i roto i te taiao pāmahana teitei, me whakaiti te wā e whakaatuhia ai te papa silicone. I roto i te taiao pāmahana iti, me whakarite kia hoki te papa silicone ki te pāmahana rūma i mua i te whakamahinga.

VI. Whakamutunga
He pānga nui tō te pāmahana ki te ngāwari o ngā papa hiku silicone. Ka whakaitihia e te pāmahana teitei te kaha o te silicone, ā, ka whakaitihia e te pāmahana iti tōna manawanui. I raro i ngā āhuatanga pāmahana tino kino, ka heke pea ngā āhuatanga ngāwari o te silicone, ka pā ki tōna roanga mahi. Mā te whiriwhiri i te rauemi silicone tika, te tirotiro me te tiaki auau, me te whakamahi tika, ka taea te whakaroa ake i te roanga mahi o te papa hiku silicone kia mau tonu ai tōna mahi i raro i ngā āhuatanga pāmahana rerekē.
