PECOAT® PVC ʻO ka uhi e hui me ka Flame Retardant UL94 V0

ʻO ka hoʻāʻo ʻana o ka UL94 V0 maʻamau

Wahi a ka hōʻike hoʻāʻo i hoʻopuka ʻia e ka hui hoʻāʻo mana honua SGS, PECOAT® PVC ka penaʻana ua hoʻokō i ka maʻamau pae UL94 V0 i ka hoʻāʻo hoʻokō ʻana i ka lapalapa ahi.

ʻO kēia ho'āʻo i kālele ʻia ma ka 50W (20mm) kūpaʻa puhi ahi o ka uhi, i hana ʻia e like me ka maʻamau o UL 94-2023 Rev.2-2024 Māhele 8. ʻO nā hōʻike hoʻāʻo he mau pepa A me nā kikoʻī o 125mm × 13.0mm × 5.3mm. Ua hana ʻia ka hoʻāʻo ma lalo o ʻelua mau kūlana, ʻo ia hoʻi ka "as-received state" (i hoʻokomo ʻia i loko o kahi kaiapuni me ka mahana o 23±2 ℃ a me kahi haʻahaʻa pili o 50±5% no 48h) a me "ma hope o ke kūlana ʻelemakule" (ʻelemakule ma kahi kaiapuni o 70±2 ℃ no 168h, a laila waiho ʻia i loko o kahi desiccator ma 23h±2 ℃). ʻElima mau laʻana i hoʻāʻo ʻia ma lalo o kēlā me kēia kūlana.

Mai nā hopena ho'āʻo, ma lalo o nā kūlana ʻelua, ʻo ka manawa hope o nā laʻana a pau ma hope o ka hoʻohana ʻana o ka lapalapa mua a me ka lua he ≤10s, a ʻo ka huina o ka manawa afterflame a me ka manawa afterglow ma hope o ka hoʻohana ʻana ʻelua o ke ahi he ≤30s. Eia kekahi, ʻaʻohe laʻana i puhi ʻia a hiki i ka mea hoʻopili, a ʻaʻohe hihia o ke ahi a i ʻole nā droplets e puhi ana i ka pulupulu. Ma waena o lākou, ʻo ka nui o ka manawa afterflame o nā hōʻailona ʻelima ma lalo o ka "ʻāina i loaʻa" ʻo 8.9s, a ma lalo o ka "ma hope o ke kūlana ʻelemakule" he 12.4s, ʻoi aku ka haʻahaʻa ma mua o nā ≤50s i koi ʻia e ka pae pae V0. Ma muli o ka ʻikepili piha, ua helu ʻia ka hana ʻana o ke ahi kūpaʻa o ka uhi ma ke ʻano he pae V0.

ʻO ka pae UL94 V0 kekahi o nā kūlana kiʻekiʻe no ka pale ʻana o ka lapalapa o nā plastics. PECOAT® PVC uhi plastisol ʻO ka hōʻea ʻana i kēia pae e hōʻike ana i kāna mau waiwai pale ahi maikaʻi loa a hāʻawi i nā hōʻoia palekana hilinaʻi no nā hiʻohiʻona noi kūpono.

ʻO ka wehewehe kikoʻī o UL94 V0 Flame Retardant Standard

He maʻamau ka UL94 no ka hoʻāʻo ʻana i ka flammability o nā mea plastik i hoʻokumu ʻia e Underwriters Laboratories (UL). Ma waena o lākou, ʻo ka pae V0 kekahi o nā māka ahi ahi kiʻekiʻe i kēia maʻamau, nona nā koi koʻikoʻi i ka hana ʻana o ka lapalapa ahi o nā mea.

Wahi a ka UL 94-2023 Rev.2-2024 Section 8 maʻamau a me nā mea pili i ʻōlelo ʻia ma ka hōʻike hōʻike, ʻo nā pae hoʻoholo kikoʻī no ka pae UL94 V0 penei:

• ʻO ka manawa ma hope o ke ahi (t1 a me t2) o kēlā me kēia mea hoʻāʻo ma hope o ka hoʻohana mua ʻana a me ka lua o ka lapalapa ʻana he ≤ 10s.​
• ʻO ka nui o ka manawa ma hope o ke ahi (hui o t1 a me t2) o 5 mau mea ho'āʻo i loko o kekahi hui kūlana he ≤ 50s.​
• He ≤ 2s ka huina o ka manawa ho'ā a me ka manawa ho'ā (t3 + t30) o kēlā me kēia mea ho'āʻo ma hope o ka hoʻohana ʻana i ke ahi.
• ʻAʻole ʻae ʻia kahi mea hoʻāʻo e puhi a hiki i ka mea hoʻopili
• ʻAʻole ʻae ʻia nā ʻāpana ahi a i ʻole nā ​​droplets e puhi i ka hōʻailona pulupulu ma lalo.​

ʻO kēia mau maʻamau e ana piha i ka hiki ke pale ʻana i ke ahi o nā mea mai nā ʻano like ʻole e like me ka manawa afterflame, ka manawa afterglow, ka wela wela a me ka hopena o nā mea wela. Hiki i nā mea i hiki i ka pae V0 ke pio koke i ka wā e hālāwai ai me kahi lapalapa hāmama, me ka haʻahaʻa haʻahaʻa o ka laha ʻana o ke ahi, hiki ke hōʻemi maikaʻi i nā pōʻino ahi a loaʻa i ka waiwai noi nui ma nā kula me nā koi kiʻekiʻe no ka hana pale ahi.
