Nō hea te rapa silicone horopeta?

 

Hei mārama ki ngā momo huarahi maha e taea ai te whakamahi i te rapa silicone, he mea nui kia mōhio ki ōna takenga mai. I roto i tēnei tuhinga, ka tirohia e tātou te pūtake mai o te silicone kia mārama ake ai ki ōna āhuatanga.

 

Te mārama ki ngā momo rapa rerekē

Hei mārama ki te tikanga o te silicone, me mōhio koe ki ngā momo rapa rerekē e wātea ana. I tōna āhua parakore, ko te rapa tūturu e mōhiotia whānuitia ana ko te rapa, ā, i ahu mai i te rākau rapa. I kitea tuatahitia ēnei rākau i Amerika ki te Tonga, ā, ko te whakamahinga o te rapa mai i roto i a rātou i ahu mai i te ahurea Olmec (ko te tikanga o Olmec ko te "Iwi Rapa"!).

Nō reira, ko ngā mea katoa kāore i hangaia mai i tēnei rapa maori, he mea hanga e te tangata, ā, e mōhiotia ana ko te rapa hangai.

Ko te matū hou i hangaia mā te whakaranu i ngā momo rauemi ka kiia he pūmua hangai. Mena he āhuatanga pīngore te pūmua, ka tohua he elastomer.

 

He aha te mea i hangaia ai te silicone?

E kiia ana te silicone he elastomer hangai nā te mea he polymer e whakaatu ana i te viscoelasticity – arā, e whakaatu ana i te matotoru me te ngāwari. E kiia ana ēnei āhuatanga ngāwari e te iwi he rapa.

He mea hanga te silicone i te waro, te hauwai, te hāora me te silicon. Kia mōhio koe he rerekē te tuhi o te kai kei roto i te silicone. Ko te silicon te kai i ahu mai i te silicon i ahu mai i te onepu. He uaua te tukanga hanga silicon, ā, he maha ngā wāhanga e uru ana. Nā tēnei tukanga uaua ka nui ake te utu o te rapa silicone ki te rapa maori.

Ko te tukanga hanga silicone ko te tango i te silicon mai i te silica ka tukuna mā roto i ngā warowaihā. Kātahi ka konatunatua ki ētahi atu matū hei hanga silicone.

 

Me pēhea te hanga o te rapa silicone?

He huinga te rapa silicone o tētahi tuara Si-O kore-waro, me ngā rōpū mahi waro e piri ana. Mā te here silicon-hāora ka ātete te silicone ki ngā pāmahana teitei me te ngāwari ki ngā whānuitanga o ngā pāmahana.

Ka konatunatua te pūmua silicone ki ngā whakakī whakakaha me ngā āwhina tukatuka hei hanga i tētahi kapia mārō, ka taea te hono atu i muri i te pāmahana teitei mā te whakamahi i ngā peroxide, i te whakamaroke polyaddition rānei. Kia honoa, ka huri te silicone hei rauemi totoka, elastomeric.

I Silicone Engineering, ka whakamaroketia ā mātou rauemi silicone katoa mā te whakamahi i te wera e whakarōpū ana i ā mātou hua silicone hei HTV silicone, hei High Temperature Vulcanised rānei. Ka whakauruhia, ka whakaranua, ka hangaia hoki ā mātou momo silicone katoa i tō mātou whare 55,000-sq. ft. i Blackburn, Lancashire. Ko te tikanga tēnei kei a mātou te whai i ngā paerewa teitei o te whakahaere kounga puta noa. Neke atu i te 2000 tāne o te rapa silicone e tukatukahia ana e mātou i ia tau, e āhei ai mātou ki te whakataetae nui i te mākete silicone.

 

He aha ngā painga o te whakamahi i te rapa silicone?

Nā te tukanga whakaputa me te hanganga rauemi o te rapa silicone, he tino ngāwari, ā, koinei te take e rongonui ai mō ngā whakamahinga maha. Ka taea e ia te tu atu i ngā piki me ngā heke o te pāmahana mai i te -60°C ki te 300°C.

He tino ātete hoki ki te taiao mai i te Ozone, te UV me ngā ahotea huarere whānui, he mea tino pai mō te hiri o waho me te tiaki i ngā wāhanga hiko pēnei i te rama me ngā ārai. He rauemi mama, he maha hoki ngā whakamahinga o te hautai silicone, he mea tino pai mō te whakaiti i ngā wiri, te whakaū i ngā hononga me te whakaiti i te haruru i roto i ngā tono kawe tangata – he mea rongonui mō te whakamahi i roto i ngā taiao pēnei i ngā tereina me ngā waka rererangi, kei reira te whakamahinga o te rapa silicone e āwhina ana i te whakamarie o te kiritaki.

He tirohanga poto noa iho tēnei mō ngā takenga mai o te rapa silicone. Heoi, e mārama ana mātou i JWT Rubber ki te hiranga o te mārama ki ngā mea katoa e pā ana ki te hua e hokona ana e koe. Mena kei te hiahia koe ki te mōhio atu ki te mahi a te rapa silicone i roto i tō umanga, whakapā mai ki a mātou i tēnei rā.
