TF-PU501 P iyo N ku salaysan ololka ee xumbo PU adag
Hordhac
TF-PU501 waa badeeco ololka celisa oo si gaar ah loogu sameeyay xumbo adag oo PU ah.Budada cawlkeedu waa halogen-free iyo bir-la'aan, oo leh qiime dhexdhexaad ah PH, iska caabin biyaha, saamaynta qiiqa wanaagsan, iyo waxtarka dib u dhigista ololka sare.
Haddii macaamiishu aysan haysan wax shuruud ah oo ku saabsan cabbirka qaybaha iyo midabada, TF-pu501 waxay aad ugu habboon tahay Pu-pu501 adag, oo siinaya xal aad u fiican oo dab-damis ah oo loogu talagalay alaabta PU ee si ballaaran loo isticmaalo nolosheena.Bulshada casriga ah, isticmaalka baahsan ee qalabka PU wuxuu noqday lagama maarmaan dhinacyo kala duwan.Haddi ay ahaan lahayd alaabta guriga, dhismaha, gaadiidka ama warshadaha hawada, shuruudaha ilaalinta dabka ayaa loo baahan yahay.
Tilmaamid
| Tilmaamid | TF-PU501 |
| Muuqashada | budada cawl |
| P2O5nuxurka (w/w) | ≥41% |
| N ka kooban (w/w) | ≥6.5% |
| Qiimaha pH (10% ganaax biyo ah, oo ah 25ºC) | 6.5-7.5 |
| Qoyaanka (w/w) | ≤0.5% |
Astaamaha
1. Budada cawl, way balaadhataa marka la kululeeyo, si hufan u xakamaysa qiiqa.
2. Biyo iska caabin heer sare ah, ma fududa in la soo dajiyo, hufnaanta dabci sare.
3. Ayoonnada birta ah ee aan halogen-ka lahayn oo aan midnaba culusayn.Qiimaha pH waa dhexdhexaad, badbaado leh oo deggan inta lagu jiro wax soo saarka iyo isticmaalka, ku habboonaanta wanaagsan, maaha in laga falceliyo ololka kale iyo kaaliyeyaasha.
Codsiga
TF-PU501 waxa loo isticmaali karaa oo keliya daawaynta ololka ama waxa loo isticmaali karaa TEP oo loogu talagalay xumbo poliurethane adag.Marka kaliya lagu daro 9%, waxay gaari kartaa codsiga OI ee UL94 V-0 .Marka keligiis lagu daro 15%, waxay gaari kartaa kala soocida B1 ee gubashada habdhaqanka qalabka dhismaha GB / T 8624-2012.
Intaa waxaa dheer, cufnaanta qiiqa xumbo waa in ka yar 100.
