Ngā Hanganga Ārai Ahi o te Polypropylene (PP) UL94 V0 me te V2

Ngā Hanganga Ārai Ahi o te Polypropylene (PP) UL94 V0 me te V2

He pūhui kirihou wera te polypropylene (PP), engari nā tōna ngāwari ki te mura ka whakawhāiti i tōna whakamahinga i roto i ētahi mara. Hei whakatutuki i ngā whakaritenga rerekē mō te ātete mura (pēnei i ngā taumata UL94 V0 me V2), ka taea te whakauru i ngā ātete mura hei whakarei ake i te ātete mura o te PP. Kei raro nei he whakataki taipitopito ki ngā whakatakotoranga PP ātete mura mō ngā taumata UL94 V0 me V2, tae atu ki te kōwhiringa ātete mura, te hoahoa whakatakotoranga, ngā tikanga tukatuka, me te whakamātautau mahi.

1. Whakataki ki ngā Whakatauranga Ārai Mura UL94

Ko te UL94 he paerewa mura i whakawhanakehia e Underwriters Laboratories (UL) hei aromatawai i te ātete mura o ngā rauemi kirihou. Ko ngā whakatauranga ātete mura noa ko:

• V0Ko te taumata ātete mura teitei rawa atu, me tineia e ngā tauira i roto i te 10 hēkona i roto i te whakamātautau tahu poutū me te kore e mura te miro me te maturuturu.
• V2He iti ake te ātete mura, e āhei ai ngā tauira ki te tineia i roto i te 30 hēkona i roto i te whakamātautau tahunga poutū, me te tuku hoki i ngā maturuturunga ka mura ai te miro.

2. Te Hanganga PP Ārai-Mumura V0

Ko te V0 ātete-mura PP e hiahia ana ki te ātete mura tino pai, ko te tikanga ka tutuki mā te whakauru i ngā ātete mura tino whai hua me te arotau i te whakatakotoranga.

2.1 Kōwhiringa Ārai Mura

• Ngā Ārai Mura i WhakapūkaratiaPērā i te decabromodiphenyl ether (DBDPO) me te tetrabromobisphenol A (TBBPA), he tino whai hua engari kāore pea i te tino pai ki te taiao.
• Ngā Ārai Mura e Hangai Ana ki te PhosphorusPērā i te ammonium polyphosphate (APP) me te whūkawa whero, he pai ake mō te taiao, he whai hua ake hoki.
• Ngā Ārai Mura Intumescent (IFR)Kei roto ko te pūtake waikawa, te pūtake waro, me te pūtake hau, e whakarato ana i te ātete mura e pai ana ki te taiao, ā, he pai hoki.
• Te konupūmā hauwaiora (Mg(OH)₂) te konumohe hauwaiora rānei (Al(OH)₃)He ārai mura kore-waro e pai ana ki te taiao, engari me nui te kawenga e hiahiatia ana.

2.2 Te Hanganga Noa

• Resin PP: 100phr (mā te taumaha, pērā anō i raro nei).
• Kare Te mura o te mura (IFR): 20–30 hēkona
• Konupora Waikawa: 10–20 whārangi
• Kaihoko Ārai-Tārere: 0.5–1 phr (hei tauira, polytetrafluoroethylene, PTFE).
• hinu whakahinuhinu: 0.5–1 phr (hei tauira, te konutea stearate).
• Ārai mate: 0.2–0.5 phr.

2.3 Ngā Tikanga Tukatuka

• WhakaranuWhakaranua kia ōrite te kapia PP, ngā mea ārai mura, me ētahi atu tāpiringa ki roto i te mīhini whakaranu tere-teitei.
• Te Whakaputa me te Whakapūtanga PelletisingWhakamahia he mīhini whakaputa wiri takirua i te 180–220°C hei whakaputa pirepire.
• Te Whakarewa WerohangaWhakawaihia ngā pirepire hei tauira whakamātautau mā te whakamahi i te mīhini whakarewa werohanga.

2.4 Whakamātautau Mahi

• Whakamātautau Tahu Poutū UL94Me tutuki i ngā tauira ngā whakaritenga V0 (ka tineia aunoa i roto i te 10 hēkona, kāore e mura te miro i te maturuturunga iho).
• Whakamātautau Āhuatanga MīhiniAromatawai i te kaha kume, te kaha pānga, me ētahi atu, kia mōhio ai kei te tutuki te mahi a te rauemi i ngā whakaritenga tono.

3. Hoahoa Hanganga PP Ārai-Mumura V2

He iti ake ngā whakaritenga ātete mura o te PP ātete-mura V2, ā, ka taea te whakatutuki mā te uta ātete-mura taurite.

3.1 Kōwhiringa Ārai Mura

• Ngā Ārai Mura i WhakapūkaratiaPērā i te DBDPO, i te TBBPA rānei, he iti noa ngā rahinga e hiahiatia ana hei whakatutuki i te V2.
• Ngā Ārai Mura e Hangai Ana ki te PhosphorusPērā i te whūkawa whero, i ngā phosphate rānei, e tuku ana i ngā otinga hoa-taiao.
• Te konupūmā hauwaiora (Mg(OH)₂) te konumohe hauwaiora rānei (Al(OH)₃)He pai mō te taiao engari me nui ake ngā kawenga.

3.2 Te Hanganga Noa

• Resin PP: 100 whārangi
• Ārai Mura Pūmua: 5–10 whārangi
• Te Trioxide Antimony (Sb₂O₃): 2–3phr (hei kaiwhakakotahi).
• Kaihoko Ārai-Tārere: 0.5–1 phr (hei tauira, PTFE).
• hinu whakahinuhinu: 0.5–1 phr (hei tauira, te konutea stearate).
• Ārai mate: 0.2–0.5 phr.

3.3 Ngā Tikanga Tukatuka

• Pērā i te tukatuka taumata-V0 (whakaranu, whakaputa, whakahāngai werohanga).

3.4 Whakamātautau Mahi

• Whakamātautau Tahu Poutū UL94Me tutuki ngā tauira i ngā whakaritenga V2 (ka tineia anō i roto i te 30 hēkona, ka whakaaetia te maturuturu).
• Whakamātautau Āhuatanga MīhiniMe whakarite kia tutuki i te mahi a ngā rauemi ngā hiahia o te tono.

4. Te Whakataurite i waenga i ngā Hanganga V0 me V2

4.1 Te Utaina Ārai Mura

• Ko te V0 e hiahia ana ki ngā kawenga teitei ake (hei tauira, 20–30phr IFR, 10–20phr Mg(OH)₂ rānei).
• Ko te V2 e hiahia ana ki ngā uta iti ake (hei tauira, ngā aukati mura brominated 5–10phr).

4.2 Te Whai Hua o te Ārai i te Mura

• He tino pai te ātete mura o te V0 mō ngā whakaritenga tino pakari.

4.3 Ngā Āhuatanga Mīhini

• Tērā pea ka pā nui ngā whakatakotoranga V0 ki ngā āhuatanga ā-pūkaha (hei tauira, te kaha pānga, te kaha kume) nā te nui ake o te ihirangi tāpiri.
• He iti ake te pānga o ngā whakatakotoranga V2 ki te mahi ā-mīhini.

4.4 Pānga ki te Taiao

• He maha ngā wā ka whakamahia e ngā hanganga V0 ngā aukati mura e pai ana mō te taiao (hei tauira, IFR, Mg(OH)₂).
• Tērā pea ka whakamahia e ngā whakatakotoranga V2 ngā aukati mura brominated, he iti ake te pai mō te taiao.

5. Ngā Taunakitanga mō te Arotautanga o te Hanganga

5.1 Te Mahi Tahi Ārai Mura

• Mā te whakakotahi i ngā momo aukati mura rerekē (hei tauira, IFR + Mg(OH)₂, brominated + Sb₂O₃) ka taea te whakanui ake i te aukati mura me te whakaiti i te kawenga.

5.2 Te Whakarerekētanga o te Mata

• Mā te whakarerekē i ngā ārai mura kore-waro (hei tauira, Mg(OH)₂, Al(OH)₃) ka pai ake te hototahitanga ki te PP, ka whakarei ake i ngā āhuatanga hangarau.

5.3 Te Arotautanga Tukatuka

• Mā te whakahaere i ngā tawhā whakaputa/werohanga (pāmahana, pēhanga, tere tīwiri) ka whakarite kia rite te mararatanga, ā, ka ārai hoki i te pirau.

6. Whakamutunga

Ko te hoahoa o ngā whakatakotoranga PP ātete-mutunga V0 me V2, e whakawhirinaki ana ki ngā whakaritenga ātete mura motuhake me ngā horopaki tono.

• Ngā whakatakotoranga V0i te nuinga o te wā ka whakamahia ngā aukati mura tino whai hua (hei tauira, IFR, Mg(OH)₂) me te mahi tahi kua arotauhia kia tutuki ai ngā paerewa pakari.
• Ngā whakatakotoranga V2ka taea te whakaiti i te ātete mura me te iti o ngā tāpiringa (hei tauira, ngā ātete mura brominated).

I ngā mahi tūturu, me whakataurite ngā āhuatanga pēnei i te ātete mura, te mahi ā-pūkaha, te pānga ki te taiao, me te utu kia pai ai te hanga me ngā tikanga tukatuka.
