I te mea e kaha haere ana ngā ture taiao me te mōhiotanga haumaru o ngā kaihoko, kua noho te hangarau polypropylene ātete-mutunga kore-halogen hei whiringa nui mō te whakataurite i te mahi a ngā rauemi me te haumaru me te tiaki taiao. Ka puta he hau paitini me te waikura i ngā ātete-mutunga kore-halogen tuku iho i te wā e tahuna ana, ko ngā ātete-mutunga V0 kore-halogen, me ō rātou āhuatanga hoa-taiao me ō rātou kaha ātete-mutunga whai hua, kei te whai wāhi nui ki ngā momo ahumahi.
01 Hangarau matua: Te mātāpono mahi me te momo ārai mura V0 kore-halogen
Ko te hangarau matua o ngā mea ārai mura V0 kore-halogen kei roto i tā rātou tikanga ārai mura intumescent ahurei. Ina pāngia e ngā pāmahana teitei, ka hangaia e ēnei mea ārai mura he paparanga pahuka waro ōrite, matotoru hoki ki runga i te mata o te rauemi. Ka ārai pai tēnei paparanga pahuka i te wera me te hāora, ā, ka aukati i te whakaputanga paowa, ā, ka eke ki te whakatauranga ārai mura V-0.
Ko ngā aukati mura hauota-intumescent te pūnaha tino noate whakamahi i te whākawa me te hauota hei mea matuaātete murangā huānga, mā te tāpiri i te 24%-26% ki te polypropylene e ranea hei whakatutuki i te paerewa UL94 V-0 mō te tauira 1.6mm. Ko tēnei momo ārai mura e tohuhia ana e te iti o te paoa, te iti o te paitini, me te atawhai ki te taiao, e tutuki ana i te aratohu taiao a te EU RoHS me ngā ture ā-rohe e tika ana.
02 Ngā wāhi tono: Mai i ngā taputapu hiko me ngā taputapu hiko ki ngā wāhanga motuka
Kua whānuitia te whakamahinga o ngā rauemi PP ātete-ahi V0 kore-halogen i roto i ngā ahumahi maha, tae atu ki:
I roto i te rāngai hikohiko me ngā taputapu hiko, e whakamahia whānuitia ana ēnei ārai mura mō ngā tono ārai mura i roto i ngā whare taputapu me ngā wāhanga rerekē, pērā i ngā whare oumu raihi, ngā whare ipu hiko, ngā whare tohatoha wai, me ngā panera pouaka whakamātao me te mīhini horoi.
I roto i te umanga motuka, e whakamahia ana ngā aukati mura V0 kore-halogen i roto i ngā wāhanga pūnaha hauhautanga motuka, ngā papatohu pokapū, me ētahi atu wāhanga.
I roto i te rāngai rauemi hanga whare, e whakamahia ana te PP ātete-mura kore-halogen i roto i ngā hua pēnei i ngā pepa me ngā papa.
03 Ngā Wāhi Mamae: Te Hototahi, Te Pūmautanga Wera, me ngā Wero Tukatuka
Ahakoa ngā painga maha o te PP ātete-mumura V0 kore-halogen, kei te mau tonu ētahi wero hangarau i roto i ngā tono mahi:
Ko te hototahi ngoikore te take matuaTe tangote haukini polyphosphate (APP)hei tauira, he mea e whakamahia whānuitia ana te aukati mura kore-halogen, ko tōna kaha polarity ka hua ake he hototahitanga ngoikore ki te polypropylene kore-polar, ka pā ngāwari ki ngā āhuatanga hangarau o te rauemi ina tāpirihia i roto i ngā rahinga nui.
Ko te kore e ranea te pumau o te wera he wero nui anō hokiHe pūhui paura mā te APP, he iti te ātete ki te wera. I raro i ngā āhuatanga tukatuka pāmahana teitei, ka pāngia e te pyrolysis, ka pirau hei matū pēnei i te ammonium phosphate, te waikawa metaphosphoric, te haukini, me te mamaoa wai. Ko ēnei hua pirau, pēnei i te waikawa metaphosphoric, e toe ana i roto i te kapia, ka pupū ake pea i te wā e hangaia ana, ka piri ki te pakitara pokepoke, ki te tīwiri rānei, ka pā kino ki te āhua o te hua me te whai huatanga o te whakaputa.
He take nui anō hoki te mimiti me te hekenga o te makukuHe kaha te wai o te APP, ka mimiti ngāwari i te makuku mai i te hau, ka heke ki te mata o te rauemi, ka ngaro. Ehara i te mea ka pā noa tēnei ki te roa o te mau o ngā āhuatanga ārai mura engari ka arahi pea ki ngā hapa o te mata o te hua.
Tāpiri nui rawaHe raruraru noa anō hoki tēnei e pā ana ki te PP ātete-mumura kore-halogen. Ki te whakatauritea ki ngā ātete-mumura tuku iho o te halogen, ko ngā pūnaha kore-halogen me nui ake te tāpiri hei whakatutuki i te paerewa V-0, e whakawero ana i ngā āhuatanga ā-pūkaha o te rauemi me te whakahaere utu.
04 Ngā Otinga me ngā Aronga Whakawhanake ā-Mārama
I te aro atu ki ngā wero hangarau o ngā tono PP ātete-mumura V0 kore-halogen, kua whakawhanakehia e te umanga ētahi otinga whai hua:
-He huarahi whai hua te maimoatanga mata me te arotau i te whakatakotoranga hei whakapai ake i te hototahitanga.
-He mea nui anō hoki te arotau i te whakahaere tukanga.
-Ko te whakawhanake i ngā pūnaha ātete mura hou te otinga matua.
