Phunzirani pa zovala za nsalu za ozimitsa moto aramid opanga mapepala

Pofuna kuthana ndi mavuto omwe alipo mu kafukufuku wa nsalu zoletsa moto komanso zotsutsana ndi malo amodzi, njira yosakanikirana ndi ulusi wapamwamba kwambiri ndi ulusi wotsekemera wamoto ndi organic conductive fibers inayikidwa patsogolo, kuti apange nsalu zonse za thonje lawi lamoto ndi zomveka bwino. katundu wa flame retardant ndi anti-static properties, mphamvu yapamwamba kuvala kukana ndi kumva zofewa. Monga ife tonse tikudziwa, nsalu CHIKWANGWANI monga zinthu polima ali kutchinjiriza mkulu, buku kukana ake enieni ndi 10 12 ~ 10 16 Ω · masentimita, apamwamba kwambiri kuposa 10 8 ~ 10 9 Ω·cm odana malo amodzi mlingo, kotero nsalu yake ndi yosavuta. kuti apange kuchuluka kwa magetsi osasunthika omwe amagwiritsidwa ntchito. M'malo oyaka komanso kuphulika, mphamvu ya electrostatic discharge ngati gwero loyatsira nthawi zambiri imayambitsa ngozi zoyaka ndi kuphulika. Kumbali inayi, ulusi wambiri wa nsalu ndi zinthu zomwe zimatha kuyaka kapena kuyaka, ndipo malire ake a oxygen index nthawi zambiri amakhala pakati pa 17 ndi 25, otsika kwambiri kuposa mtengo wozimitsa wokha wa 27 mumlengalenga. Nsaluyo ikakumana ndi magwero osiyanasiyana oyatsira, kuphatikiza ma electrostatic discharge sparks, imayaka mwachangu ndikuyambitsa moto. Choncho thonje lamoto retardant odana malo amodzi nsalu ndi chitetezo cha anthu. Malinga ndi kafukufuku ndi kafukufuku, m'zaka zaposachedwa, pakupanga mafakitale ndi moyo wapagulu,wopanga mapepala a aramidngozi zomwe zimadza chifukwa cha kuyaka kwa nsalu, makamaka nsalu za zovala ndi electrostatic discharge, ndiyeno kupyolera mu kutentha kwa zovala zomwe zakhala zikuchulukirachulukira, zomwe zimayika miyoyo ya anthu pangozi ndikupangitsa kuti chuma cha boma chiwonongeke kwambiri. M'magawo ambiri azachuma cha dziko (monga zakuthambo, ndege, zida, makampani opanga mankhwala, migodi) ndi malo ambiri (monga malo osungira mafuta, gasi kapena gasi, chipinda chochitira opaleshoni m'chipatala, galimoto, ndege) komanso zozimitsa moto, zankhondo. ndi madera ena ofunikira, chifukwa cha momwe zinthu zogwirira ntchito zimapangidwira komanso momwe chilengedwe chimakhalira, ndizosavuta kuyambitsa moto pogwiritsa ntchito ma electrostatic discharge sparks kapena nsalu zina. Choncho, pofuna kuonetsetsa chitetezo chaumwini cha ogwira ntchito oyenerera, zovala zotetezera zomwe zimagwiritsidwa ntchito m'madipatimenti ndi malo omwe ali pamwambawa ziyenera kukhala ndi ntchito ziwiri za zovala zotetezera moto komanso zovala zoteteza anti-static, osati ntchito imodzi yotetezera. Choncho, chitukuko cha flame retardant nsalu odana malo amodzi n'kofunika kwambiri.wopanga mapepala a aramid

CVC lawi retardant nsalu amapangidwa ndi Proban ammonia fumigating ndondomeko twill nsalu okhazikika kutsirizitsa, makulidwe a 0.5 mm, gram kulemera 320 g/m2. Njira ya Proban ndiyotchinjiriza nsalu za thonje zosapsa ndi moto ndi THPC(4-hydroxymethyl chloride) zoletsa moto kudzera mu kuviika, kuyanika, kufukiza kwa ammonia, okosijeni, kutsuka, kuyanika ndi njira zina. Izi zimadziwika kuti ndi njira yomwe ili ndi zotsatira zabwino zoletsa moto, kutsika pang'ono kwa mphamvu ya nsalu komanso kukopa pang'ono pamanja. Kapangidwe kake koletsa malawi ndi njira yochepetsera malawi pamachitidwe amoto, ndiko kuti, pansi pa kutentha kwakukulu komwe kumapangidwa ndi kuyaka kwa THPC flame retardant, mbali imodzi, phosphoric acid imatulutsidwa ngati chotchinga mpweya, kwinakwake. dzanja, asidi phosphoric amachitira ndi mapadi mu nsalu thonje, kupanga CHIKWANGWANI catalyzed, wopanda madzi ndi carbonized, ndi gulu polyphosphic asidi ndi ogwirizana kwambiri.wopanga mapepala a aramid

Mwabwinobwino, imatha kuchepetsa kupanga gasi woyaka ndikukwaniritsa cholinga chochepetsa mphamvu yamoto. 2.2 PVC filimu zakuthupi PVC filimu zakuthupi ndi woonda filimu zinthu ndi buluu wodaya wothandizila anawonjezera, makulidwe ndi 0.14mm, ali ndi ntchito zabwino lawi retardant. Kachitidwe kake koletsa moto ndi chiphunzitso cha gasi wosayaka. Kutentha kwa PVC

HCl imalumikizana ndi ma chain free radicals (H · ndi OH ·) mulawi lamoto, zomwe zimapangitsa kuti ma free radicals omwe amagwira ntchito kwambiri asinthe kukhala maatomu a Cl osagwira ntchito, ndipo ma atomu a Cl amachotsa maatomu a H kuchokera mumafuta a polima (RH) kupanga HCl, motero. kuletsa kukula kwa moto. The mineralization

Phunzirani ma equation ndi awa: h. + HC – H2 + Cl · OH · + HX – H2O + Cl, RH + X, –, HCl + R, 2.3 kwa filimu ya PE yochuluka kwambiri, filimu ya PE.
