Singano yosatentha ndi moto yokhomerera nsalu yosalukidwa

Chigawo chachikulu cha polyester flame retardant non-woluck nsalu ndi polyester, amene ndi polymerization mankhwala terephthalic acid kapena diethyl terephthalate ndi ethylene glycol. Makhalidwe ake ndi awa: mphamvu zambiri, kusungunuka kwabwino, kukana kutentha kwabwino, malo osalala, kukana kuvala bwino, kukana kuwala kwabwino, kukana kwa dzimbiri, komanso kusachita bwino kwa utoto. The lawi retardant limagwirira makamaka kumaphatikizapo Kuwonjezera wa retardants lawi, amene ndi mtundu wa zinthu zina zowonjezera ntchito poliyesitala mapulasitiki, nsalu, etc. Kuwonjezera pa polyvinyl kolorayidi akhoza kukwaniritsa lawi retadancy poonjezera poyatsira mfundo kapena kulepheretsa kuyaka kwake, potero kupititsa patsogolo chitetezo cha moto wa zinthu.

Gulu la zoletsa moto

Pali mitundu yambiri ya zoletsa malawi, kuphatikizapo halogenated flame retardants, organophosphorus ndi phosphorous halide flame retardants, intumescent flame retardants, ndi inorganic flame retardants. Pakali pano, brominated flame retardants amagwiritsidwa ntchito kwambiri mu halogenated flame retardants.

Kugwiritsa ntchito nsalu yotchinga moto yosawomba

Nsalu ya Yang Ran yosalukidwa imagwiritsidwa ntchito makamaka ngati sofa, mipando yofewa, matiresi, zoseweretsa, nsalu zapakhomo, zovala, ndi zina zotero.

Chiweruzo njira kwa flame retardant sanali nsalu nsalu

1. Kutulutsa kutentha sikungathe kupitirira 80 kilowatts.

2. Mphindi 10 zapitazo, kutentha kwathunthu sikuyenera kupitirira 25 MJ.

3. Kuchuluka kwa CO kutulutsidwa kuchokera ku chitsanzo kumaposa 1000 PPM kwa mphindi zoposa 5.

4. Mukawotcha nsalu zosawotcha zamoto, kuchuluka kwa utsi sikudutsa 75%.

5. Flame retardant sanali nsalu nsalu ndi woyera koyera, ndi mawonekedwe ofewa, makamaka elasticity wabwino ndi chinyezi permeability, kupangitsa kuti kwambiri kuyanjidwa ndi anthu.

6. Kugwiritsa ntchito ulusi wachilengedwe woletsa moto, palibe chodabwitsa cha madontho amadzimadzi.

7. Imakhala ndi mphamvu yozimitsa yokha ndipo imapanga wosanjikiza wandiweyani wa carbides panthawi yakuyaka. Mpweya wochepa wa carbon dioxide umatulutsa utsi wochepa chabe wapoizoni.

8. Flame retardant sanali nsalu nsalu ali khola alkalinity ndi asidi kukana, si poizoni, ndipo sapanga zochita mankhwala.

Kuyesa kwa nsalu zosalukidwa zomwe sizimawotcha moto

Nsalu zosalukidwa ndi flame retardant zimakhala ndi mphamvu yoletsa moto komanso anti droplet, zomwe zimatha kupanga ma firewall oletsa moto.

① Zomwe zili mu mayeso a US CFR1633: Mkati mwa nthawi yoyesera ya mphindi 30, kutentha kwapamwamba kwa matiresi kapena matiresi sikuyenera kupitirira 200 kilowatts (KW), ndipo mkati mwa mphindi 10 zoyamba kutulutsidwa, kutentha kwathunthu kuyenera kukhala kosakwana 15 megajoules (MJ).

Kagwiritsidwe: Amagwiritsidwa ntchito makamaka mu matiresi, mipando ya mipando, sofa, mipando, ndi nsalu zapakhomo.

② Miyezo yayikulu yoyesera ya BS5852 yaku Britain imaphatikizapo kuyesa kutayira ndudu ndi kuyerekezera machesi ndi malawi a acetylene, komanso kuwona kutalika kwa kuwonongeka. Kwenikweni, choyatsira chimagwiritsidwa ntchito kuyaka chokwera pamwamba pa nsalu kwa masekondi 20, ndipo lawilo lizimitsa mkati mwa masekondi 12 mutasiya lawi.

③ Mayeso a US 117: Mayeso a ndudu, osapitirira 80% ya gawo lotenthedwa, osapitirira mainchesi 3 a kutalika kwanthawi yayitali, osapitirira mainchesi 4 a kutalika kwakukulu koyaka, osapitilira 4 masekondi anthawi yoyaka, osapitilira 8 masekondi a nthawi yayitali yoyaka, komanso osapitirira 4% ya kutaya misa pa kuyaka kwamoto.
