Nailoni me te Polyester: Ngā Rerekētanga, me pēhea te wehewehe i waenganui i a rāua?

1. Te Hanganga:

Nairona (Polyamide):He pūmua hangai te nairona, e mōhiotia ana mō tōna pakari me tōna kaha. I ahu mai i ngā matū hinu, ā, nō te whānau polyamide. Ko ngā monomer e whakamahia ana i roto i tōna hanga ko ngā diamine me ngā waikawa dicarboxylic.

Polyester (Polyethylene Terephthalate):Ko te polyester tētahi atu pūhui hangai, he mea nui mō tōna ngāwari ki te whakamahi me te ātete ki te totoro me te whakaiti. Nō te whānau polyester, ā, he mea hanga mai i te ranunga o te waikawa terephthalic me te ethylene glycol.

2. Ngā Āhuatanga:

Nairona:E mōhiotia ana ngā muka nairona mō tō rātou kaha whakaharahara, te ātete ki te pakū, me te ngāwari. He pai hoki te ātete ki ngā matū. He maeneene, he ngawari, he tere te maroke o ngā papanga nairona. He maha ngā wā ka whakamahia mō ngā mahi e hiahia ana kia roa te mau, pērā i ngā kākahu hākinakina, ngā taputapu o waho, me ngā taura.

Polyester:He mea nui ngā muka polyester mō tō rātou ātete pai ki ngā kita, te roa, me te ātete ki te harore me te mimiti. He pai te āhua o ēnei muka, ā, he ngāwari te tiaki. Ahakoa kāore ngā papanga polyester i te ngohengohe, i te ngāwari rānei pērā i te nairona, he tino ātete ki ngā āhuatanga taiao pērā i te rā me te makuku. He mea noa te polyester hei whakamahi i roto i ngā kākahu, i ngā taonga whare, me ngā mahi ahumahi.

3. Me pēhea te wehewehe:

Tirohia te Tapanga:Ko te huarahi māmā ki te tautuhi mēnā he nairona, he polyester rānei te papanga, ko te tirotiro i te tapanga. He maha ngā hua kakahu he tapanga e whakaatu ana i ngā rauemi i whakamahia mō te hanganga.

Te Kakano me te Āhua:He ngawari ake, he ngāwari ake hoki ngā papanga nairona ki te whakatauritea ki te polyester. He maeneene ake te kakano o te nairona, ā, tera pea he pahekeheke ake te pā atu. I tetahi atu taha, he mārō ake, he ngoikore ake hoki ngā papanga polyester.

Whakamātautau tahunga:Mā te whakahaere whakamātautau wera ka āwhina i te wehewehe i waenga i te nairona me te polyester, engari me tūpato. Tapahia he wahi iti o te papanga ka pupuri ki te tweezers. Whakakāhia te papanga ki te mura. Ka mimiti te nairona i te mura, ā, ka waiho he toenga mārō, rite ki te pirepire e mōhiotia ana ko te pungarehu. Ka rewa te polyester, ka maturuturu, ka hanga he pirepire mārō, rite ki te kirihou.
