Hoʻohālikelike ʻenehana: ʻO ke ahi-Retardant vs Standard plastic poly sheeting roll

I loko o ka ʻenehana hoʻopaʻa ʻana a me nā noi kūkulu, koho i nā mea kūpono ʻōwili pepa poli plastik he mea koʻikoʻi no ka paʻa o ke kūkulu ʻana a me ka palekana o ka pae. ʻOiai ʻo nā ʻano like ʻelua e lilo i mau pale makū maikaʻi, ʻokoʻa loa kā lākou molecular additives a me ka hana ma lalo o ke kaumaha wela. Ke loiloi nei kēia loiloi i ka ʻepekema waiwai a me nā kūlana hoʻoponopono e hoʻokaʻawale i kēia mau ʻāpana kiʻiʻoniʻoni ʻelua.

Mechanisms Molecular Composition and Flame Retardancy Mechanisms

• 1. Polyethylene base resin : He kūlana ʻōwili pepa poli plastik hana 'ia mai ka Low-Density Polyethylene (LDPE) a i 'ole Linear Low-Density Polyethylene (LLDPE) pellets me ka 'ole o nā mea ho'ohui kūikawā.
• 2. Halogenated vs Phosphorus mea hoʻohui : He aha ka mea e pale ai i ke ahi pili i ka hoʻokomo ʻana i nā mea hoʻopaʻa ahi kemika i ka wā o ke kaʻina extrusion. Ke hana nei kēia mau mea hoʻohui i ka māhele kinoea e kinai i nā radical manuahi a i ʻole i ka pae paʻa e hana i kahi papa char pale.
• 3. Hana maʻamau vs FR Grade drip : I ka wā e puhi ai, hoʻoheheʻe ka polyethylene maʻamau i ka polymer hoʻoheheʻe ʻia, hiki ke hoʻolaha i ke ahi. Hoʻolālā ʻia nā kiʻiʻoniʻoni FR i hoʻopaʻa ʻia e hoʻopau iā ia iho i loko o kekona kekona o ka wehe ʻana i ke kumu ahi.

Hoʻokō hoʻoponopono a me nā kūlana palekana ahi

ʻO ka hoʻokō ʻana i nā code hale kūloko e kuhikuhi pinepine i ka pono o nā kiʻiʻoniʻoni kūikawā. Hoʻohālikelike mākou i nā koi hōʻoia no nā māka polyethylene like ʻole ma lalo.

• 1. ʻO ka NFPA 701 ka hoʻokō ʻana no ka pepa poli : ʻO kēia ka hoʻāʻo ʻana i ka flammability vertical maʻamau i ka ʻoihana. A ʻōwili pepa poli pale ahi Pono e hoʻohana i kēia no ka hoʻohana ʻana i nā wahi ākea, nā halemai, a i ʻole ke kūkulu hale kiʻekiʻe.
• 2. ʻO ka ASTM E84 Nā ʻano ahi ahi : Ke ana keia hoao i ka Flame Spread Index (FSI) a me ka Smoke Developed Index (SDI). Hoʻopau pinepine nā kiʻiʻoniʻoni maʻamau i kēia mau ana, ʻoiai nā kiʻiʻoniʻoni FR e loaʻa i nā helu papa A.
• 3. LPS 1207 pono palapala : Ma ka mākeke UK, pono nā kiʻiʻoniʻoni i hoʻohana ʻia no ka pale kūloko i ka wā o ka hoʻoponopono hou ʻana i kēia "Loss Prevention Standard" e hoʻokō i nā kauoha inikua.

Paʻa kino a me ka hana ʻana i ka ʻauke ʻea

• 1. ʻO ka ikaika tensile a me ke kū'ēʻana i ka puncture : ʻOiai ka hoʻohui ʻana o nā mea pale ahi, ʻo ka ikaika tensile o 6 mil poly sheeting Pono e noho ma luna o 1700 psi no ka ASTM D882 e hōʻoiaʻiʻo ʻaʻole ia e haehae ma lalo o ka makani a i ʻole ka hele wāwae.
• 2. ʻO ka māhu (Perm Rating) : Pehea ka ʻokoʻa o ka pale mahu mai ka uhi ahi ? Ma keʻano loea, hiki iā lākou ke like. Hāʻawi nā mea ʻelua i ka helu perm ma lalo o 0.1 no ka ASTM E96, ʻoiai ʻo nā kiʻiʻoniʻoni FR ka mea ma mua i nā wahi "hana wela".
• 3. Ke kū'ē i ka hoʻohaʻahaʻa UV : No ke aha he mea koʻikoʻi ka pale ʻana o UV no ka pale poly plastic ma muli o ka photo-oxidation o ka polyethylene. No ka mālama ʻana i waho, ua hoʻohui ʻia nā mea hoʻopaʻa māmā ʻeleʻele a i ʻole nā ​​mea hoʻopaʻa kukui amine (HALS) e hoʻonui i ke ola o ka ʻōwili ma mua o 6 mahina.

Nā Koho Koho Kūikawā no ka noi

• 1. Kokoke wahi encapsulation pono : Oiai a ʻōwili pepa poli poli kaumaha kaumaha (10 mil a 20 mil) ka mea maʻamau no ka mālama ʻana i ka wai, nā code kūkulu hale ma kekahi mau ʻāina i kēia manawa e koi i nā kiʻi ʻoniʻoni FR-rate inā hoʻohana ʻia ka wahi no nā plenums mechanical.
• 2. Nā ʻāpana hoʻohaʻahaʻa a me ka hoʻopaʻa ʻana : Ma ke alakai a i ole asbestos abatement, ka ʻO ka ʻōwili pepa poli maʻamau maʻamau vs ka pale ahi Hoʻoholo ʻia ka hoʻopaʻapaʻa e nā lula palekana; Pono ke kiʻiʻoniʻoni FR e pale i nā ahi uila i loko o nā pā paʻi ʻino.
• 3. ʻO nā ʻāpana lepo no ka manawa : No ka hoʻomalu ʻana i ka lepo no ka wā pōkole ma nā wahi hiki ʻole ke puhi ʻia, ʻoi aku ka nui o ke kiʻi ʻoniʻoni 4 mil a i ʻole 6 mil maʻamau a ʻoi aku ka maikaʻi.

FAQ ʻenehana

1. Ua pau anei ka poli pale pale ahi?
Hoʻokomo ʻia nā mea hoʻohui ahi i loko o ka polimer matrix a ʻaʻole "holoi," akā hiki ke hoʻohaʻahaʻa ka paʻa holoʻokoʻa o ka ʻōwili i ka manawa inā e ʻike ʻia i ka wela nui a i ʻole ka radiation UV.

2. Hiki iaʻu ke hoʻohana i ka poly sheeting maʻamau no nā ʻāpana "hana wela"?
ʻAʻole. ʻO ka polyethylene maʻamau kahi huahana i hoʻokumu ʻia i ka ʻaila e hana i wahie i ke ahi. ʻO nā kiʻiʻoniʻoni i hōʻoia ʻia NFPA 701 wale nō e pono ke hoʻohana ʻia ma kahi o ka wili a i ʻole ka wili ʻana.

3. He aha ka mānoanoa mil maʻamau no nā ʻōwili papa hana?
Hoʻohana ka hapa nui o nā noi ʻoihana i 6 mil, 10 mil, a i ʻole 20 mil mānoanoa ma muli o ke kūpaʻa ʻana o ka puncture a me ka lōʻihi o ka papahana.

4. ʻAʻole wai wai ka pale ahi-retardant?
ʻAe, paʻa ia i nā waiwai hydrophobic like me ka polyethylene maʻamau, e lilo ia i mea pale maikaʻi loa a me ka mahu.

5. Pehea e hiki ai iaʻu ke hoʻomaopopo i ka pepa helu FR ma kahi kahua hana?
Paʻi maʻamau ʻia nā ʻōwili FR i hōʻoia ʻia me ka NFPA 701 a i ʻole ASTM E84 hōʻoia ma luna o ke kiʻiʻoniʻoni no ka nānā ʻana.
