ʻO ka papa PP pale ahi e pili ana i ka plastik PP me ka lapalapa ahi, a hiki ke hele i ka hoʻāʻo ROHS, ʻaʻohe alakaʻi, chromium, mercury a me nā metala kaumaha ʻeono.ʻO ka polypropylene he mea ʻawaʻawa ʻole, ʻaʻala ʻole, ʻono waiu keʻokeʻo keʻokeʻo polimer kristal kiʻekiʻe, ʻo 0.90 wale nō -” 0.91g /cm3, ʻo ia kekahi o nā ʻano māmā o nā plastics āpau.Paʻa loa ka papa PP flame retardant i ka wai, ʻo 0.01% wale nō ka wai absorption, ke kaumaha mole ma kahi o 8 tausani 150 tausani.

Nā hiʻohiʻona o ka papa PP pale ahi
Loaʻa i ka papa flame retardant PP nā hiʻohiʻona o ka non-flammable, hoʻopau iā ia iho a me ke kūpaʻa wela kiʻekiʻe.ʻO ka pā pale ahi, ʻike ʻia hoʻi ʻo ka lapalapa ahi, ka lapalapa ahi, ka papa ʻaina ahi e like me ka plywood, hana ʻia ka ʻoki ʻoki ʻana i lāʻau a i ʻole ma ka lāʻau pahu pahu i ʻoki ʻia i loko o nā ʻāpana liʻiliʻi o ka lāʻau ʻāpana o ka lāʻau hoʻopaʻa ʻia i ke ahi me ka hoʻopili hou ʻana. ma hope o ekolu papa a multilayer plywood, maʻamau me ka helu 'ē aʻe o nā papa lāʻau, a hana i ka papa pili o ka lāʻau fiber kuhikuhi perpendicular agglutination.
1, pale ʻana i ka ʻino o ka papa PP pale ahi.
2, pale ʻana i ka hopena o ka papa PP i ka lapalapa ahi: ʻo ka papa PP pale ahi i kāna mea maka polypropylene i ka hopena hopena i ka plastik mua.
3, ka pale ʻana o ka papa PP pale ahi: ʻo ka paʻa ʻana o ka maikaʻi o ka papa papa PP, ke kūpaʻa ʻelemakule maikaʻi, hiki ke kanu ʻia ma lalo o ka lepo, 50 mau makahiki o ka ʻelemakule.
4 ke ola kino o ka papa PP paa i ka lapalapa ahi: ka papa polipropylene me ka ono ole, ka mea ole, ka ala ole, ka ino ole, ke ola kaiapuni.

Ka hoʻohana ʻana i ka papa PP pale ahi
I kēia manawa, ua hoʻohana nui ʻia ka papa PP pale ahi i ka ʻoihana kemika, ka hana mīkini, ka hana uila, ka hana kaʻa, ka mining, ka ʻenekini kamaʻilio, ka hana mana a me nā ʻano ʻē aʻe.

ʻO ka papa ʻauamo ʻana i ka lapalapa o ka papa PP
I kēia manawa, nui nā ʻano e loiloi ai i ka hiki ʻana o ka lapalapa, e like me ka hoʻoholo ʻana i ka oxygen index determination, horizontal a vertical combustion test, etc. Ke piʻi aʻe nei ka pae ahi o nā plastics i kēlā me kēia pae mai HB, V-2, V-1 a i V-0 :
1, HB: ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ma UL94 maʻamau.Pono i ka lihi kuni ma lalo o 40 mm i kēlā me kēia minuke no nā laʻana 3 a 13 mm mānoanoa;No nā laʻana ma lalo o 3 mm mānoanoa, ʻoi aku ka nui o ka puhi ahi 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 10-kekona hoʻāʻo ʻana ma ka hāpana, e pio ka lapalapa i loko o 60 kekona.Hiki iā ʻoe ke hāʻule i ka puhi ahi.
3, V-1: ma hope o ʻelua 10-kekona hoʻāʻo ʻana ma ka hāpana, e pio ka lapalapa i loko o 60 kekona.ʻAʻole hiki ke hāʻule nā ​​mea puhi ahi.
4, V-0: ma hope o ʻelua 10-kekona hoʻāʻo ʻana ma ka hāpana, e pio ka lapalapa i loko o 30 kekona.ʻAʻole hiki ke hāʻule nā ​​mea puhi ahi.
