Ngā Pūrongo - Whakatauhia ngā Wero o te Huka EVA

I ngā tau tata nei, kua kitea te kī tonu o te mākete hu o te ao, ā, kua kaha ake te whakataetae i waenga i ngā waitohu waenga ki te teitei. Nā te rerenga tonu mai o ngā ariā me ngā hangarau hou i roto i ngā hu kua akiaki i te tono nui mō ngā rauemi pahuka i roto i te umanga hanga hu. Kua noho ngā rauemi pahuka polymer mahi teitei hei tūāpapa mō ngā otinga hua waitohu maha, inā koa i roto i te rāngai hu hākinakina.

E toru ngā wāhanga matua o tētahi takirua hū hākinakina paerewa: te taha o runga, te taha waenga, me te taha o waho.

He mea nui te waenga o te waewae hei whakarato i te whakamarie, te pekepeke, me te mimiti i te kaha pānga i te wā hākinakina. Mā tēnei ka tiakina, ka whakamarie hoki, ka waiho hei wairua o ngā hū hākinakina. Ko te rauemi me te hangarau pahuka o te waenga o te waewae e wehewehe ana i ngā hangarau matua o ngā waitohu nui.

EVA—Te Rauemi Pahuka Tuatahi i Whakamahia mō ngā Hu:

Ko te ethylene-vinyl acetate copolymer (EVA) te rauemi pahuka tuatahi e whakamahia ana i roto i ngā waenga waewae. Ko te pahuka EVA parakore he 40-45% te kaha o te whakahokinga, he nui ake i ngā rauemi pēnei i te PVC me te rapa i roto i te pakari, me ngā āhuatanga pēnei i te mama me te ngāwari o te tukatuka.

I roto i te ao hu, e toru ngā momo o ngā tukanga pahuka matū a EVA: te pahuka nui papatahi tuku iho, te pahuka iti i roto i te pokepokea ai, me te pahuka honohono-wero.

I nāianei, ko te werohanga whakawhiti-hononga pahuka kua noho hei tukanga matua mō te tukatuka rauemi hu.

Ngā Wero o te Huka EVA:

Ko tētahi raruraru noa o ēnei pahuka EVA tuku iho ko tōna ngāwari iti, e pā ana ki tō rātou kaha ki te whakarato i te urunga me te tautoko tino pai, inā koa i roto i ngā mahi pēnei i ngā hū hākinakina. Ko tētahi atu wero noa ko te puta o te pēhanga me te whakahekenga wera i roto i te wā, e pā ana ki te roa o te wā. Heoi anō, i roto i ngā mahi e tino nui ana te ātete ki te paheke me te ātete ki te karawarawa, ka kore pea te pahuka EVA tuku iho e tutuki i ngā paerewa e hiahiatia ana.

Hei whakarei ake i ngā āhuatanga ā-tinana o ngā hua pahuka EVA, he maha ngā wā ka whakaurua e ngā kaihanga ngā rauemi rapa pēnei i te EPDM, te POE, ngā OBC, me te TPE pēnei i te SEBS ki ngā rauemi mata EVA. Ko te whakaurunga o te EPDM mō ngā āhuatanga rapa, te POE mō te rapa teitei, ngā OBC mō te tioata ngohengohe, te TPE mō te ngāwari, me ētahi atu, e whai ana kia tutuki ngā whāinga whakarerekētanga. Hei tauira, mā te tāpiri i ngā elastomers POE, ka taea te whakanui ake i te manawanui o ngā hua ki te 50-55%, ki runga ake rānei.

Huka EVA Auaha: Kaiwhakarerekē Si-TPV mō te Kounga Teitei me te Mahi Whakapai Ake

He huarahi rerekē a SILIKE Si-TPV i roto i te EVA, ehara i te mea ka aro noa ki ngā take mahi engari ka hangai hoki ki ngā kaupapa hoahoa taiao.
