TF-PU501 P me N e hāngai ana te mura mura mo te pahuka i PU mārō
Kupu Whakataki
Ko te TF-PU501 he hua mura ahi i tino whakawhanakehia mo te pahuka i te PU.Ko tana paura hina he halogen-kore me te whakarewa taumaha-kore, me te uara PH koretake, te aukati wai, te pai o te aukati auahi, me te pai o te mura o te ahi.
Mena kaore he whakaritenga a nga kaihoko mo nga rahi me nga tae o te matūriki, he tino pai te TF-pu501 mo te Pu maaro mo te mura ahi, e whakarato ana i te otinga whakamarumaru ahi pai mo nga rauemi PU e whakamahia nuitia ana i roto i o tatou oranga.I roto i te hapori hou, ko te whakamahi whanui o nga rauemi PU kua waiho hei mea nui ki nga momo waahi.Ahakoa i roto i nga taonga, te hanga, te kawe waka, nga umanga aerospace ranei, ka hiahiatia nga whakaritenga tiaki ahi.
Whakatakotoranga
| Whakatakotoranga | TF-PU501 |
| Te ahua | paura hina |
| P2O5ihirangi (w/w) | ≥41% |
| N ihirangi (w/w) | ≥6.5% |
| Uara pH (10% te whakatārewatanga wai, i te 25ºC) | 6.5-7.5 |
| Makuku (w/w) | ≤0.5% |
Nga ahuatanga
1. Te paura hina, ka whakawhānui ina wera, he pai ki te whakakore i te auahi.
2. He pai te atete ki te wai, kaore i te ngawari ki te whakaheke, te kaha o te mura o te ahi.
3. Kore-kore me te kore he katote whakarewa taumaha.Ko te uara pH he koretake, he haumaru me te pumau i te wa e whakaputa ana me te whakamahi, he pai te hototahi, kia kaua e tauhohe ki etahi atu mura me te awhina.
Taupānga
Ka taea te whakamahi i te TF-PU501 anake i roto i te maimoatanga mura, ka whakamahia tahi ranei me TEP mo te pahuka polyurethane pakari.A, no te takitahi tāpiri 9%, ka taea e tae te reira OI tono o UL94 V-0 .Ina taapiri takitahi te 15%, ka taea e ia te whakarōpūtanga B1 mo te mahi tahu o nga rawa hanga me te GB / T 8624-2012.
He aha atu, he iti iho i te 100 te kiato auahi o te pahuka.
