Me pēhea te whakaiti i te matotoru o te paoa mō te piripiri epoxy mā te whakamahi i te aukati mura AHP me te MCA?

Mā te tāpiri o te konumohe hypophosphite me te MCA ki te piri epoxy ka nui ake te tukunga paowa. He mea taea te whakamahi i te konutea borate hei whakaiti i te matotoru me te tukunga paowa, engari me arotau te hanganga o nāianei mō te ōwehenga.

1. Te Tikanga Whakaiti Auahi o te Konutea Pōrata

He mea whai hua te konutea borate hei pehi paowa, hei āwhina hoki i te mura. Ko ōna tikanga ko:

• Whakatairanga Hanga WaruKa hanga he paparanga waro matotoru i te wā e tahuna ana, ka wehea te hāora me te wera, ka whakaiti hoki i te tukunga hau mura.
• Te aukati i te paowa: Ka whakatere i ngā tauhohenga hononga-whiti hei whakaiti i te whakaputanga o ngā matūriki paowa, ka whakaiti i te mātotoru paowa (he tino whai hua mō ngā pūmua pēnei i te epoxy).
• Pānga WhakakotahiKa whakarei ake i te ātete mura ina whakakotahihia ki ngā ātete mura e hangai ana ki te ūkuikui (hei tauira, te konumohe hypophosphite) me te hauota (hei tauira, te MCA).

2. Ngā Rongoā Whakaiti Auahi Rerekē, Tāpiri rānei

Hei whakapai ake i te pehi paowa, whakaarohia ēnei otinga mahi tahi e whai ake nei:

• Ngā Matū Molybdenum(hei tauira, te konutea molybdate, te molybdenum trioxide): He pai ake i te konutea borate engari he utu nui ake; e taunakihia ana kia whakaranua ki te konutea borate (hei tauira, te konutea borate: te konutea molybdate = 2:1).
• Konumohe/Makenehiuma HauwaioraMe nui te uta (20-40 phr), ka pā pea tēnei ki ngā āhuatanga ā-pūkaha o te epoxy—kia āta whakatikatika.

3. Ngā Whakarerekētanga Hanganga i Manakohia

Ki te whakaaro ko te whakatakotoranga taketake kokonumohe hypophosphate + MCA, anei ngā tohutohu arotau (i runga i te kapia epoxy 100 wāhanga):

Kōwhiringa 1: Tāpiri Tika o te Konutea Pōrata

• Te hypophosphate konumohe: Whakaitihia mai i te 20-30 phr ki15-25 haora
• MCA: Whakaitihia mai i te 10-15 phr ki8-12 haora
• Konutea borate: Tāpirihia5-15 haora(tīmata te whakamātautau i te 10 phr)
• Te tapeke o te ihirangi ārai muraPuritia ki30-40 haora(āraia te nui rawa o te tāpiringa kia kore ai e pā kino ki te mahi a te piri).

Kōwhiringa 2: Te Hononga Konutea Borate + Konutea Molybdate

• Konumohe hypophosphate:15-20 haora
• MCA:5-10 haora
• Konutea borate:8-12 haora
• Konutea molibdate:4-6 ngā tāngata
• Te tapeke o te ihirangi ārai mura:30-35 haora.

4. Ngā Inenga Whakamana Matua

• Ātete ki te mura: UL-94 tahunga poutū, whakamātautau LOI (whāinga: V-0, LOI rānei >30%).
• Te Matotoru o te AuahiWhakamahia he taputapu whakamātautau kiato paowa (hei tauira, te rūma paowa NBS) hei whakatairite i te whakahekenga o te Whakatauranga Kiato Auahi (SDR).
• Ngā Āhuatanga MīhiniKia tino tutuki te kaha kume me te kaha piri i ngā whakaritenga i muri i te whakamaroke.
• Te āheinga tukatuka: Whakaūtia te mararatanga ōrite o ngā ārai mura, me te kore e pā ki te matotoru, ki te wā whakapakeke rānei.

5. Ngā Whakaaroaro

• Te Mana Whakahaere Rahi MatūrikiKōwhiria te konutea borate rahi-nano (hei tauira, te rahi o te matūriki <1 μm) hei whakapai ake i te mararatanga.
• Whakarerekētanga MataWhakamaoritia te konutea borate ki tētahi kaihoko hononga silane hei whakarei ake i te hototahitanga ki te kapia epoxy.
• Te Whakatutukitanga o ngā TureMe whakarite kia tutuki i ngā aukati mura kua tīpakohia te RoHS, REACH, me ētahi atu ture.

6. Tauira Whakatakotoranga (Tohutoro)

7. Whakarāpopototanga

• He kōwhiringa whai hua te konutea borate hei whakaiti i te tukunga paowa. E taunaki ana kia tāpirihia10-15 haorame te whakaiti pārekareka i te ihirangi konumohe hypophosphite/MCA.
• Hei pehi atu i te paowa, whakaranua ki ngā matū molybdenum (hei tauira,4-6 ngā tāngata).
• Me whakamana te whakamātautau hei whakataurite i te ātete mura, te pehi paowa, me ngā āhuatanga hangarau.
