4. Arotautanga UtuTāpirihia te 10–15 phr ATH hei whakaiti i te utu, ahakoa ka piki ake te utaina whakakī katoa.

Te Tukanga Whakaranu i Manakohia

(Mō te rapa silicone tāpiri-whakaora e rua ngā wāhanga)

1. Te Maimoatanga-Mua o te Rapa Turanga:

• Utaina te rapa silicone (hei tauira, te kāpia 107, te hinu vinyl silicone) ki roto i te mīhini whakaranu aorangi, tangohia te hau i raro i te korehau mēnā e tika ana.

1. Tāpiri Ārai Mura:

• Ngā paura ārai mura (hei tauira, ATH, MH):
• Tāpirihia kia maha ngā puranga, whakaranua ki te rapa turanga (whakaranua kia tere mārire, 10–15 meneti) kia kore ai e haaputuputu.
• Whakamarokehia ki te 80–120°C mēnā he waiora.
• Ngā wai ārai mura (hei tauira, ngā phosphates):
• Whakaranua tika ki te hinu silicone, te hononga whakawhiti, me ētahi atu, i raro i te kutikuti teitei (20–30 meneti).

1. Ētahi atu Tāpiri:

• Tāpirihia ngā whakakī (hei tauira, te silica), te hononga whakawhiti (hydrosilane), te whakakorikori (platinum), me ngā aukati i ia wā.

1. Te Whakaōrite:

• Whakamahinga anō i te mararatanga mā te whakamahi i te mira hurihuri-toru, i te emulsifier kutikuti-teitei rānei (he mea nui mō ngā nano-tāpiri pēnei i te CNT).

1. Te tango hau me te tātari:

• Wetewete hau korehau (-0.095 MPa, 30 min), tātari mō ngā whakaritenga parakore teitei.

Ngā Whakaaro Matua

• Kōwhiringa Ārai Mura:
• Ko ngā aukati kore-halogen (hei tauira, ATH) me whai rahi matūriki angiangi (1–5 μm); ka kino te taumaha nui ki ngā āhuatanga ā-pūkaha.
• He pai ake te hototahitanga o ngā aukati i hangaia ki te silicone (hei tauira, ngā kapia phenyl silicone) engari he nui ake te utu.
• Whakahaere Tukanga:
• Te pāmahana ≤ 60°C (ārai i te paihana konukōkiri konukōkiri, te whakamaroke wawe rānei).
• Haumākū ≤ 50% RH (ka karo i ngā tauhohenga i waenga i te hinu hydroxyl silicone me ngā ārai mura).

Whakamutunga

• Te Hanganga PapatipuWhakaranua ngā ārai mura ki te rapa turanga kia pai ai te whai huatanga.
• Ngā Whakaritenga Pūmautanga TeiteiWhakaranua i te wā e whakaranua ana hei whakaiti i ngā mōrearea rokiroki.
• Ngā Pūnaha Ārai Mura NanoMe whakamahi te marara kutikuti-teitei hei ārai i te kohikohinga.
