Fakitale yotchinga moto yopangira nsalu zitatu zotsutsana ndi nsalu

Nsaluyo imakana ulusi wa pre-oxidized wokhala ndi kukana kwambiri kutentha kwapamwamba komanso aramid yokhala ndi mphamvu zapamwamba kwambiri, nkhungu yayikulu, kukana kutentha kwambiri komanso kukana kuvala, kusakanikirana molingana ndi gawo linalake. Gonjetsani kuipa kwa ulusi awiriwa. Ubwino wa ulusi wonsewo umagwiritsidwa ntchito.

Flame retardant grade: Kuvuta kwa index iyi ndi kupota kwa silika wokhala ndi okosijeni ndi aramid. Flame-retardant zinthu zovala zosawotcha moto opanga nsalu pambuyo kukhazikitsa zambiri, kasinthidwe ndi luso lasinthidwa kwambiri, kuti mlingo kupota ndi ulusi khalidwe wakhala bwino kwambiri, ndi kupota.fakitale ya pepala ya aramidmlingo unafika kuposa 80%. Pambuyo pakuyezetsa koyenera kwa bungwe lalikulu, zizindikiro za nsalu zafika pamiyezo yoyenera, zitha kupangidwa ndi kutentha kwambiri, kutsekereza kutentha, zovala zoteteza moto. Nsaluyo sikuti imakhala ndi mphamvu zabwino zokha, kukana kuvala, komanso kuletsa moto kwambiri, kukana kutentha kwambiri, kukana kutentha kwa kutentha, malingana ndi mtengo wamtengo wapatali wamtundu womwewo wa 1113, pali chiyembekezo chabwino kwambiri cha ntchito. Nsalu iyi yatsimikiziridwa ndi ogwiritsa ntchito kuti azilamulira zenizeni, m'malo a nsalu zotetezera za UV, kutentha kwapamwamba kwambiri, madontho osungunuka a kutentha, moto woyaka ndi zina zotero. Nsaluyo imakhala ndi kukana kutentha kwambiri, kutsekereza kutentha, ntchito yamoto yobwezeretsanso ntchito yamitundu yambiri ndi yabwino, mphamvu yayikulu komanso mphamvu yolamulira yokhazikika imachepa pang'ono.fakitale ya pepala ya aramid

2 Ambiri ntchito flame retardant ndi moto retardant nsalu yothandiza gulu: zosiyanasiyana lawi retardant, gulu njira ndinso zosiyanasiyana. Malinga ndi lawi retardant zinthu, zikhoza kugawidwa mu halogenated lawi retardant, phosphorous lawi retardant, asafe lawi lawi, etc. Malinga ndi ntchito lawi retardant ndi polima mu mawonekedwe, ogaŵikana kuwonjezera mtundu ndi anachita mtundu; Malinga ndi kulimba kwa nsalu yotchinga moto, imatha kugawidwa m'mitundu itatu: yomaliza yamoto wosakhazikika, yotsalira yamoto yokhazikika komanso yomaliza yoziziritsa moto. Malinga ndi mtundu wa pawiri akhoza kugawidwa mu zochita kupanga lawi retardant ndi organic lawi retardant. Zotsatirazi makamaka zimabweretsa zovala zogwirira ntchito zoyaka moto zomwe zimagawidwa ndi njira ziwiri zomaliza.

1.1 Gulu ndi kulimba kwa nsalufakitale ya pepala ya aramid

1) osakhala chokhazikika lawi retardant kumaliza wothandizila: amatchedwanso zosakhalitsa lawi retardant kumaliza wothandizira, ambiri a iwo ndi madzi sungunuka (kapena emulsion) mchere mchere. Chotsitsa chamoto chimasungunuka m'madzi, ndipo nsaluyo imatha kugwiritsidwa ntchito pambuyo poviika ndi kuumitsa. Palinso kusamba kawiri, kusamba kwachiwiri ndi ammonia kapena koloko phulusa, kotero kuti okusayidiyo imayikidwa pa nsalu. Njirayi ndi yophweka komanso yotsika mtengo, koma kumverera kwa nsalu kumakhala kovutirapo, ndipo kutentha kwamoto kumachepa kwambiri pambuyo posamba. Nthawi zambiri amagwiritsidwa ntchito povala zovala zodzitetezera.

(2) Kutsirizitsa chotchinga chamoto chokhazikika: nsalu zotchinga moto zomwe zimagwiritsidwa ntchito ndi njirayi zimatha kutsukidwa pang'onopang'ono kwa 1 ~ 10, koma osagonjetsedwa ndi kutentha kwa sopo. Njirayi imaphatikizapo njira ya urea phosphoric acid (yomwe nthawi zambiri imatchedwa njira ya Banflam), njira ya phosphate yamkodzo, ammonium phosphate - methyl acetate mix solution solution.

(3) Durability lawi retardant kumaliza wothandizila: Njira mankhwala ntchito polymerization kapena condensation pa pamwamba pamwamba pa CHIKWANGWANI kupanga madzi-insoluble polima, ndi kukana kutsuka zambiri chofunika kupitirira 30 nthawi. Njira zazikuluzikulu zikuphatikizapo njira ya Ciba (CP) ndi njira ya Proban. Njira ya CP idapangidwa ndi Ciba Company, Switzerland. Njirayi ndi yosavuta kugwiritsa ntchito ndipo mphamvu yoletsa moto ndi yodabwitsa. Choyipa ndichakuti kutayika kwamphamvu kwa nsalu ndikokulirapo ndipo chikoka pakuchita kwa chovalacho ndi chachikulu. Njira ya Proban inalengedwa ndi British Aubry Wilson Co., LTD., Njirayi yomaliza nsalu, moto woyaka moto ndi wabwino, makamaka pambuyo pa chithandizo cha nsalu ndi kukonzanso mwamphamvu sikungafanane ndi njira ina iliyonse yomaliza, koma njirayi ndi yoopsa kwambiri, kuipitsidwa kwakukulu kwa chilengedwe, kotero kukwezedwa kuli kochepa.

2.2 Gulu la zoletsa moto potengera mtundu wapawiri

(1) inorganic lawi retardant: Inorganic lawi retardant ndi udindo waukulu wa kutentha mayamwidwe, mitundu waukulu ndi antibacterial deodorant nsalu aluminium hydroxide, magnesium hydroxide, wofiira phosphorous, antimony oxide, molybdenum okusayidi, ammonia molybdate, nthaka borate, nthaka okusayidi, zirconia. , zirconia, zirconia, etc., zomwe ndi aluminium hydroxide, magnesium hydroxide, red phosphorous, antimony oxide ndi zomwe zimagwiritsidwa ntchito kwambiri, makamaka aluminiyamu hydroxide, magnesium hydroxide sichitha kungoyimitsa moto, komanso imatha kusewera Kudzaza zochita. Iwo ali ndi mawonekedwe a kukhazikika kwamafuta abwino, kuchita bwino kwambiri, kuponderezana kwa utsi, kukana kudontha, kudzaza kotetezeka, kwenikweni osaipitsa chilengedwe komanso mtengo wotsika mtengo, ndi zina zambiri, ndipo akhala akugwiritsidwa ntchito kwambiri pazinthu zoletsa moto wa halogen. Koma organic lawi retardant moto retardant nsalu kukana kuchapa ndi osauka, ichi ndi chifukwa organic lawi retardant ali amphamvu polarity ndi hydrophilicity, ndipo sanali polar nsalu ngakhale ndi osauka. Pa nthawi yomweyi, kuti akwaniritse zofunikira zowonongeka ndi moto, zowonjezera zowonongeka zamoto zimawonjezedwa mochuluka, zomwe zimakhudza kwambiri makina ndi kukonza zinthu. Chifukwa chake, m'zaka zaposachedwa, kafukufuku wokhudza kuwongolera bwino kwambiri komanso kusanja kwamankhwala oletsa moto wachilengedwe walandira chidwi chosaneneka. Komanso, pofuna kuchepetsa kuchuluka kwa lawi retardant ndi chimodzimodzi lawi retardant zotsatira, ndinso kafukufuku malangizo lawi retardant m'zaka zaposachedwa kuphatikiza lawi retardant ndi kuphunzira synergistic zotsatira za lawi retardant.

(2) organic lawi retardants: organic lawi retardants anawagawa phosphorous mndandanda ndi halogen mndandanda. Zakale ndizochepa kwambiri pakugwiritsa ntchito. Ma halogenated flame retardants makamaka ndi chlorine ndi bromine. Komabe, zotsatira za chlorine flame retardants ndi zoipa kwambiri kuposa bromine lawi retardants, chifukwa si zophweka kubala chlorine gulu ufulu. Anti-khwinya ndi sanali ironing nsalu, Komanso, chifukwa dzimbiri ndi kawopsedwe wa bromide pambuyo matenthedwe kuwola ndi yaing'ono, kotero pang'ono ntchito akhoza kukwaniritsa chimodzimodzi lawi retardant kwenikweni monga kolorayidi. Chifukwa chake, ma brominated flame retardants ndiofala kwambiri. Komabe, kuchokera kumalingaliro a ntchito yonse, chifukwa cha zolephera za halogenated flame retardants, zomwe zimakhala ndi halogenated acid muzinthu zawo zowola, utsi waukulu komanso zovulaza thupi la munthu, zimasinthidwa pang'onopang'ono ndi nsalu zina zoletsa moto komanso zosawotcha moto. zowonjezera.
