Te Hanga Tohutoro mō ngā Kirihou PVC Ārai-Mumura V-0

Te Hanga Tohutoro mō ngā Kirihou PVC Ārai-Mumura V-0

Hei whakatutuki i te whakatauranga ātete mura V-0 (e ai ki ngā paerewa UL-94) i roto i ngā kirihou PVC thermoplastic, ko te konumohe hypophosphite me te waikawa boric ngā mea e rua e whakamahia whānuitia ana hei ārai mura. Me arotau ngā taumata tāpiri i runga i te hanganga motuhake, ngā tikanga tukatuka, me ngā whakaritenga mahi. Kei raro nei ētahi taunakitanga me ngā awhe tohutoro:

1. Taumata Tāpiri o te Hypophosphite Konumohe

He ārai mura whai hua te hypophosphite konumohe, he mea hanga ki te phosphorus, he mea tika mō ngā rauemi PVC. Ka ārai i te mura mā te hanga i tētahi paparanga phosphate tiaki me te tuku i te hau waikawa phosphoric.

• Taumata tāpiri kua tūtohutia: 15–25 ngā wā(ngā wāhanga mō ia rau wāhanga o te kapia)
• Mō te PVC paerewa, me tāpiri atu20 phrKo te tikanga, ka eke te konumohe hypophosphite ki te whakatauranga ātete mura V-0.
• Mō te ātete mura nui ake, ka taea te whakanui ake i te horopeta, engari me whai whakaaro ki te pānga ki ngā āhuatanga miihini.
• Ngā Whakatūpato:
• Mā te nui rawa o te konumohe hypophosphate ka whakaiti i te mahi tukatuka (hei tauira, he ngoikore te rere o te wai).
• E taunakihia ana kia whakakotahitia me ētahi atu aukati mura (hei tauira, te waikawa boric, te konumohe hauwaiwai) kia pai ai te mahi tahi.

2. Te Taumata Tāpiri o te Waikawa Boric

He iti te utu o te waikawa boric hei ārai mura, ā, ko tana mahi matua ko te pirau i roto i ngā wera me te hanganga o tētahi paparanga tiaki rite ki te karāhe.

• Taumata tāpiri kua tūtohutia: 5–15 ngā wā
• Ko te waikawa boric te tikanga e whakamahia ana hei ārai mura tuarua, ā, ko te nui rawa o te waikawa ka kino pea ki ngā āhuatanga miihini me te tukatuka.
• I roto i te PVC, te tāpiri huri noa10 haoraKa taea e te waikawa boric te mahi tahi me te konumohe hypophosphate hei whakarei ake i te ātete mura.
• Ngā Whakatūpato:
• He waimeha te waikawa boric, nō reira me karo te mimiti o te makuku i te wā e penapena ana, e whakahaeretia ana hoki.
• He iti noa iho tōna pānga ātete-mura ina whakamahia takitahi; i te nuinga o te wā ka honoa ki ētahi atu ātete-mura (hei tauira, te konumohe hypophosphite, te konumohe hauwaiwai).

3. Te Hanganga Tahi o te Hypophosphite Konumohe me te Waikawa Boric

Hei whakatutuki i te whakatauranga V-0, ka taea te whakakotahi i te konumohe hypophosphate me te waikawa boric mō ngā pānga mahi tahi. Kei raro nei tētahi whakatakotoranga tohutoro:

• Konumohe hypophosphate: 15–20 ngā haora
• Waikawa Pōrika: 5–10 ngā wā
• Ētahi atu tāpiringa:
• Kaiwhakaahua (hei tauira, DOP): Kia rite ki te hiahia (ka whakarerekētia i runga i ngā whakaritenga pakeke PVC)
• Kaiwhakaū:2–5 ngā wā(hei tauira, ngā tote mata, ngā mea whakaū konupūmā-konutea)
• Hinu Whakahinuhinu:0.5–1 phr(hei tauira, te waikawa stearic)

Tauira Whakatakotoranga:

• Kapia PVC:100 ōrau
• Konumohe hypophosphate:18 tau te pakeke
• Konutea borate:8 haora
• Kaiwhakaahua Kirihou (DOP):40 ōrau
• Kaiwhakaū:3 ngā tāngata
• Hinu Whakahinuhinu:0.8 phr

4. Te Whakamātautau me te Arotau

I roto i ngā mahi whaihua, e taunakihia ana ngā mahi e whai ake nei mō te whakamātautau me te arotau:

1. Te whakatakotoranga whakamātautau:Whakaritea he whakamātautau tauine iti i runga i ngā awhe tohutoro.
2. Whakamātautau UL-94:Whakahaerehia ngā whakamātautau mura poutū hei aromatawai i te kaha o te ātete ki te mura.
3. Whakamātautau mahi:Aromatawai i ngā āhuatanga ā-pūkaha (hei tauira, te kaha kume, te kaha pānga) me te mahi tukatuka (hei tauira, te rere o te wai, te pumau o te wera).
4. Arotautanga:Whakatikatikahia ngā taumata tāpiri o te konumohe hypophosphite me te waikawa boric, tāpirihia rānei ētahi atu mea ārai mura (hei tauira, te konumohe hydroxide, te antimony trioxide) hei whakapai ake i te mahi.

5. Ngā Whakaaro Matua

• Te pāmahana tukatuka:He tino teitei ngā pāmahana pirau o te konumohe hypophosphate me te waikawa boric; kia kaua e neke ake ngā pāmahana tukatuka i ēnei rohe hei karo i te pirau.
• Te mararatanga:Me whakarite kia ōrite te horapa o ngā ārai mura ki roto i te PVC hei ārai i ngā raruraru kukū ā-rohe.
• Pānga ki te taiao:He ārai mura e pai ana mō te taiao te konumohe hypophosphite me te waikawa boric, engari me manatoko te hototahitanga ki ētahi atu tāpiringa.

6. Whakamutunga

Hei whakatutuki i te whakatauranga ātete mura V-0 i roto i ngā kirihou kirihou PVC, ko ngā taumata tāpiri kua tūtohutia ko15–25 phr mō te hypophosphate konumoheme5–15 phr mō te waikawa boricMā te whakamahi tahi o ēnei ārai mura ka taea te whakapai ake i te mahi. I roto i te mahi, he mea nui te arotau i runga i ngā whakatakotoranga me ngā whakaritenga mahi motuhake, ā, me whakahaere te whakamātautau UL-94 hei manatoko i te whakatauranga ārai mura.
