Ka whakatairangahia e te elastomer e ahu mai ana i te silicone thermoplastic vulcanizate hihiri a Si-TPV te hangarau pahuka EVA

whakaahuahia:

Ko te Ethylene vinyl acetate (EVA) he copolymer maha-whakamahinga i hangaia mā te whakaranu i ngā monomers ethylene me te vinyl acetate. Ko te ōwehenga o te ihirangi vinyl acetate (VA) i roto i te EVA ka rerekē mai i te 2% ki te 60%, ka taea te whakarite i ōna āhuatanga. Ko te EVA me te ihirangi VA iti iho, tata ki te 3 wt%, e whakamahia whānuitia ana hei whakarerekē i te polyethylene, ko ngā hanganga he ihirangi VA teitei ake, mai i te 5 ki te 50 wt%, ka kitea ngā tono i roto i te hanga kiriata whakaitiiti, te takai kai, me ngā hu, me ētahi atu.

Ko te elastomer Si-TPV hihiri vulcanizate thermoplastic silicone-based he whakarerekētanga pahuka EVA auaha, ngāwari te horoi. Ka taea te whakamahi hei whakarerekētanga pahuka EVA mō ngā nohoanga, Ka taea te whakamahi hei whakarerekētanga pahuka EVA mō ngā nohoanga, pahuka EVA whakarerekētanga mō ngā taputapu tiaki, pahuka EVA whakarerekētanga mō ngā taonga tākaro hanga, pahuka EVA whakarerekētanga mō ngā pare waewae, ā, ka taea hoki e ia te whakapai ake i te hangarau o ngā hu oma pahuka Eva. He painga ōna ki te whakaiti i te whakahekenga wera o te pahuka EVA, te whakapai ake i te ātete me te ātete ki te pakū, te whakapai ake i te whakarerekētanga o te rauemi i te pēhanga, me te whakatairanga i ngā kōhao mirumiru kia ōrite me te matotoru.

Ngā Painga Matua

01

Whakapai ake i te ngāwari o ngā rauemi pahuka EVA

Ki te whakaritea ki te paura paparua, ki te kaihoko ārai-pakura rānei, he pai ake te ngāwari o te Si-TPV.
02

Whakapai ake i te mātotorutanga o te tae o ngā rauemi pahuka EVA

Tērā pea ka taunekeneke ētahi rōpū i runga i te Si-TPV me ngā chromophores tae, ka whakarei ake i te mākū o te tae.
03

Whakaitihia te whakahekenga wera o ngā rauemi pahuka EVA

Mā te ngāwari o te Si-TPV ka tukuna te ahotea o roto o te rauemi pahuka EVA.
04

Whakapai ake i te ātete ki te kakahu me te kore e memeha o ngā rauemi pahuka EVA

Ka taea e Si-TPV te whai wāhi ki te tauhohenga o te kaihoko honohono-whiti, e whakanui ana i te kiato honohono-whiti.
05

Te whakapūtanga rerekē

Ka horapa ōrite te Si-TPV i roto i te rauemi pahuka EVA, ka taea te āwhina i te hanganga pūtau.
06

Whakaitihia te rerekētanga kōpeketanga o ngā rauemi pahuka EVA

He pai te ātete o Si-TPV ki te pāmahana teitei me te pāmahana iti, ā, ka taea e ia te whakapai ake i te rerekētanga o te pēhanga pāmahana teitei me te pāmahana iti o ngā rauemi pahuka EVA pakeke ake.

Te Pūmautanga Te Whakapūmautanga

He hangarau matatau kāore he whakarewa, kāore he kirihou, kāore he hinu whakangawari, ā, kāore he kakara.
Te tiaki taiao me te āheinga ki te hangarua.
E wātea ana i roto i ngā whakatakotoranga e tutuki ana i ngā ture.

Aratohu pahuka EVA

Ko ngā āhuatanga o te raupapa Si-TPV 2250 he ngāwari ki te kiri mō te wā roa, he ātete pai ki ngā paru, kāore he mea whakangawari me te mea whakapūmau i tāpirihia, ā, kāore he ua i muri i te whakamahinga mō te wā roa, he mea tino pai te whakamahi mō te whakarite rauemi pahuka EVA tino māmā, tino ngāwari, ā-taiao hoki.

Auahatanga i roto i ngā rauemi EVA Foam (4)

I muri i te tāpiri i te Si-TPV 2250-75A, ka paku heke te mātotoru o te pūtau mirumiru o te pahuka EVA, ka matotoru te pakitara mirumiru, ā, ka marara te Si-TPV i roto i te pakitara mirumiru, ka taratara te pakitara mirumiru.

Mā te whakauru i ngā whakarerekētanga Si-TPV ki roto i ō tukanga hangahanga, ka taea e ngā pakihi te whakaputa i ngā rauemi pahuka EVA kua whakarei ake i te ātete, te roa, me te whakamarie, e tutuki ai ngā tono maha, tae atu ki ngā kapu hū, ngā hua horoi, ngā taonga hākinakina mō te whakangahau, ngā whāriki papa/yoga, me te maha atu.

He rerekē ki tōna hoa haurua-kiriata, te polyethylene, ko te whakaurunga o ngā monomer VA ka whakararu i te hanganga o ngā tioata i roto i te mekameka polymer, ka heke te kiriata. I te pikinga ake o te ihirangi VA, ka memeha haere te EVA, ka puta he huringa ki ōna āhuatanga ā-tinana me ā-mīhini. Ahakoa ka piki ake ngā tawhā pēnei i te roa i te wā whati, te pāmahana whakawhiti karāhe, me te mātotoru me te pikinga ake o te ihirangi VA, ka heke iho ētahi atu tawhā pēnei i te kaha kume, te modulus, te pakeke, me te pāmahana rewa. Heoi, ahakoa tōna ngāwari ake, tera pea ka whakaatu te EVA i ngā ngoikoretanga o te kaha haehae, te ātete kakahu, me te huinga pēhanga, inā koa i roto i ngā tono e hiahia ana kia pakari.

Hei whakakore i ēnei herenga, he maha ngā wā ka whakaranua te EVA ki ngā rapa, ki ngā elastomer thermoplastic rānei (TPE), hei whakapai ake i te kaha kume, te ātete haehae, te ātete ki te pakū, me te manawanui matū ki te whakataurite ki te EVA parakore. Mā te whakaranu i te EVA ki ngā TPE pēnei i te polyurethane thermoplastic (TPU) me ngā elastomer polyolefin (POE) ka whakarei ake i ngā āhuatanga viscoelastic me te whakahaere i te tukatuka me te hangarua. Hei tāpiri, ko te putanga mai o ngā copolymers poraka olefin (OBC) ka tukuna he āhuatanga elastomeric me te ātete pāmahana teitei. Ko te hanganga ahurei o te OBC, kei roto ko ngā wāhanga mārō ka taea te tioata me ngā wāhanga ngohengohe kore-āhua, ka taea te mahi pai ake i roto i ngā tono maha, me ngā āhuatanga huinga kōpeketanga e rite ana ki te TPU me te TPV.
Heoi, ko te SILIKE Si-TPV dynamic vulcanizate thermoplastic elastomer e ahu mai ana i te silicone he mea hou rawa atu. Ki te whakatauritea ki ngā mea pēnei i te OBC me te POE, ko ngā mea matua o te Si-TPV ko: ● Te whakapai ake i te ngāwari o ngā rauemi pahuka EVA ● Te whakapai ake i te mātotoru o te tae o ngā rauemi pahuka EVA ● Te whakaiti i te whakahekenga wera o ngā rauemi pahuka EVA ● Te whakapai ake i te ātete ki te mau o ngā rauemi pahuka EVA ● Ka taea e te Si-TPV te whakapai ake i te rerekētanga o te pēhanga pāmahana teitei me te iti o ngā rauemi pahuka EVA pakeke ake.
