ʻO ka papa PP pale ahi e pili ana i ka plastik PP me ka pale ahi, a hiki ke hala i ka hoʻāʻo ROHS, ʻaʻohe kēpau, chromium, mercury a me nā metala kaumaha ʻeono ʻē aʻe. ʻAʻohe ʻawaʻawa o ka Polypropylene, ʻaʻohe ʻala, ʻaʻohe ʻono waiū keʻokeʻo kiʻekiʻe, ʻo ka density he 0.90 wale nō - "0.91g /cm3, ʻo ia kekahi o nā ʻano māmā o nā plastics āpau. He paʻa loa ka papa PP pale ahi i ka wai, ʻo ka helu omo wai he 0.01% wale nō, ʻo ke kaumaha molekala ma kahi o 8 tausani 150 tausani.

Nā ʻano o ka papa PP pale ahi
ʻO ka papa PP pale ahi he mau ʻano o ka pale ʻole i ke ahi, hoʻopau ponoʻī a me ke kūpaʻa wela kiʻekiʻe. ʻO ka papa pale ahi, i ʻike ʻia hoʻi he pale ahi, pale ahi, papa plywood pale ahi e like me ka plywood, ʻoki ʻoki rotary i hana ʻia i loko o ka lāʻau a i ʻole e ʻoki ʻia i loko o nā ʻāpana liʻiliʻi o ka lāʻau kuea o ka lāʻau pale ahi me ka hoʻopili ʻana i ka glue ma hope o ʻekolu papa a i ʻole multilayer plywood, maʻamau me kahi helu ʻē o nā papa o ka lāʻau, a hana i ka papa e pili ana o ka fiber lāʻau i kuhikuhi ʻia i ka agglutination perpendicular.
1, pale lapalapa PP papa i ka palaho.
2, lapalapa pale wela PP papa hopena: ʻo kāna mea maka polypropylene pale wela PP papa i ka plastic mua.
3, pale ahi i ka ʻelemakule o ka papa PP: kūpaʻa ka maikaʻi o ka papa PP pale ahi, kūpaʻa maikaʻi i ka ʻelemakule, lepo, hiki ke kanu ʻia i lalo o ka honua, a hiki ke ʻelemakule i loko o 50 mau makahiki.
4. ʻAʻohe ʻawahia ka papa PP lapalapa lapalapa: ʻAʻohe ʻawahia ka mea maka o ka papa PP polypropylene maka, ʻaʻohe ʻawahia, ʻaʻohe ʻala, ʻaʻohe ʻinoʻino, a he olakino maikaʻi loa ia no ke kaiapuni.

Ka hoʻohana ʻana o ka papa PP flame retardant
I kēia manawa, ua hoʻohana nui ʻia ka papa PP flame retardant i ka ʻoihana kemika, hana mīkini, hana lako uila, hana kaʻa, mining, ʻenekinia kamaʻilio, kūkulu mana a me nā ʻoihana ʻē aʻe.

Papa PP pale ahi
I kēia manawa, nui nā ʻano hana e loiloi ai i ka pale ʻana i ka lapalapa, e like me ka hoʻoholo ʻana i ka helu kuhikuhi oxygen, ka hoʻāʻo ʻana i ke kuni ʻana i ka pae a i ʻole ke kū pololei, a pēlā aku. Hoʻonui ʻia ka papa pale lapalapa o nā plastics i kēlā me kēia pae mai HB, V-2, V-1 a i V-0:
1, HB: ʻo ia ka papa haʻahaʻa loa o ka pale ahi ma ke kūlana UL94. Pono ka nui o ke kuni ʻana ma lalo o 40 mm i kēlā me kēia minuke no nā laʻana he 3 a 13 mm ka mānoanoa; No nā laʻana ma lalo o 3 mm ka mānoanoa, ʻo ka nui o ke kuni ʻana ma lalo o 70 mm i kēlā me kēia minuke; A i ʻole e hele i waho ma ka hōʻailona 100mm.
2, V-2: ma hope o ʻelua mau hoʻāʻo kuni ʻana he 10 kekona ma ka hāpana, e pio ka lapalapa i loko o 60 kekona. Hiki iā ʻoe ke hāʻule i lalo ke kuni ʻana.
3, V-1: ma hope o ʻelua mau hoʻāʻo kuni ʻana he 10 kekona ma ka hāpana, e pio ka lapalapa i loko o 60 kekona. ʻAʻole hiki ke hāʻule kekahi mea puhi ahi.
4, V-0: ma hope o ʻelua mau hoʻāʻo kuni ʻana he 10 kekona ma ka hāpana, e pio ka lapalapa i loko o 30 kekona. ʻAʻole hiki ke hāʻule kekahi mea puhi ahi.
