Ngā Otinga Ārai Mura mō ngā Kiriata Pepa PET
Ka hangaia e te kiritaki he kiriata PET mārama ātete-mumura, he matotoru mai i te 0.3 ki te 1.6 mm, mā te whakamahi i te hexaphenoxycyclotriphosphazene (HPCTP) me te whai kia whakaitihia te utu. Kei raro nei ngā whakatakotoranga kua tūtohutia me te tātari taipitopito mō ngā kiriata PET mārama ātete-mumura:
1. Tātaritanga o te Kōwhiringa Ārai Mumura
Hexaphenoxycyclotriphosphazene (HPCTP)
- Ngā Painga: Ka horapa pai ngā ārai mura e ahu mai ana i te Phosphazene i roto i te PET, ka mau tonu te māramatanga. Ko te tikanga ārai mura ko te whakakā i te mura i te āhua whakapoto me te hopu i ngā ira hau, kia pai ai mō ngā kiriata mārama.
- Inenga: E taunakitia ana kia 5%-10%. Tērā pea ka pāngia ngā āhuatanga ā-pūkaha e te nui rawa o ngā rahinga.
- Utu: He nui te utu, engari ka taea tonu te whakahaere i te utu katoa ahakoa he iti ake ngā kawenga.
Konumohe Hypophosphite
- Ngā Huakore: Ka puta pea te kohu i ngā paura kore-waro, ka pā kino ki te mārama. Tērā pea me whakamahi i te rahi matūriki tino kikokore, me whakarerekē rānei i te mata mō te whakamahinga pea.
- Te Whaihuatanga: Kāore i te tūtohutia kia whakamahia ko ia anake; ka taea te whakaranu ki te HPCTP hei whakaiti i te utu katoa (me whakamātautau te māramatanga).
2. Ngā Kōwhiringa Hanganga i Manakohia
Kōwhiringa 1: Pūnaha HPCTP Kotahi
- Te hanganga: 8%-12% HPCTP + rauemi turanga PET.
- Ngā Painga: Te māramatanga tino pai me te kaha ātete mura teitei (ka taea te whakatutuki i te UL94 VTM-2, VTM-0 rānei).
- Whakatau Tatau Utu: I te utaina 10%, ko te pikinga utu mō ia kg o te PET he tata ki te ¥10 (¥100/kg × 10%).
Kōwhiringa 2: Ranunga HPCTP + Konumohe Hypophosphite
- Te hanganga: 5% HPCTP + 5%-8% konumohe hypophosphate + rauemi turanga PET.
- Ngā Painga: Te whakaiti i te utu, mā te hypophosphate konumohe e āwhina te aukati i te mura o te hau, ka whakaiti pea i te whakamahinga o te HPCTP.
- Kia mōhio: Me whakamātauria te māramatanga (tērā pea ka puta he kohu iti i te konumohe hypophosphate).
3. Ngā Taunakitanga mō te Tukatuka me te Whakamātautau
- Tukanga Marara: Whakamahia he mīhini whakaputa tīwiri-rua hei whakarite kia ōrite te mararatanga o ngā ārai mura, kia kore ai hoki e pupū te puehu, e pā kino ki te māramatanga.
- Whakamātautau Ārai Mura: Arotakehia kia rite ki ngā paerewa UL94 VTM, ki te Oxygen Index (OI) rānei, me te aro ki te OI > 28%.
- Whakamātautau Mārama: Inehia te kohu mā te whakamahi i te mita kohu, kia mōhio kei raro i te 5% te kohu (te matotoru o te kiriata: 0.3-1.6 mm).
4. Whakataurite Utu
Ripanga Uta me te Whakanui Utu Ārai Mura
| Ārai Mura | E utaina ana | Te Pikinga Utu mō ia kg PET |
|---|---|---|
| HPCTP (takitahi) | 10% | ¥10 |
| HPCTP + Hypophosphite Konumohe | 5% + 5% | ¥6.8 [(5×100 + 5×37)/100] |
| Konumohe Hypophosphite (takitahi) | 20% | ¥7.4 (kāore i te tūtohutia) |
5. Whakamutunga
- Kōwhiringa Pai: HPCTP anake i te 8%-10%, e whakataurite ana i te māramatanga me te ātete mura.
- Kōwhiringa Rerekē: He ranunga o te HPCTP me te konumohe hypophosphate, me manatoko i te māramatanga me ngā pānga mahi tahi.
Taunakitanga: Me whakahaere tuatahi e te kiritaki ngā whakamātautau iti, me te arotahi ki te ātete mura (UL94/OI) me te whakamātautau kohu, kātahi ka arotau i te hanganga me te tukanga. Mena e hiahiatia ana he whakaiti utu anō, tūhuratia he konumohe hypophosphite kua whakarerekētia te mata, he ārai mura hou rānei kei runga i te phosphorus.
