Flame retardant non-woluck nsalu ndi mtundu wa nsalu zosalukidwa zokhala ndi zinthu zoletsa moto, zomwe zimagwiritsidwa ntchito kwambiri m'magawo monga zomangamanga, magalimoto, ndege, ndi zombo. Chifukwa cha zinthu zake zabwino kwambiri zoziziritsira moto, nsalu zotchingira moto zomwe siziwombedwa zimatha kuletsa kufalikira ndi kufalikira kwa moto, potero zimatsimikizira chitetezo cha miyoyo ya anthu ndi katundu.

Kukana moto kwa nsalu zopanda nsalu

Nsalu zopanda nsalu ndi mtundu watsopano wa zinthu zachilengedwe zomwe zimagwiritsidwa ntchito kwambiri pakuyika, zachipatala, zanyumba ndi zina chifukwa cha mawonekedwe ake apadera. Choyamba, ziyenera kumveka bwino kuti nsalu zosalukidwa sizifanana ndi nsalu, chifukwa zida zonsezi zimakhala ndi mapangidwe osiyanasiyana komanso njira zopangira. Kukaniza kwa moto kwa nsalu zopanda nsalu kumakhudzidwa ndi zinthu zosiyanasiyana, monga kuchuluka kwa ma polymerization a zinthu, chithandizo chapamwamba, makulidwe, etc. Kutentha kwa nsalu zopanda nsalu kumadaliranso mphamvu za ulusi wawo ndi zomatira. Nthawi zambiri, ulusi wabwino komanso ulusi wochepa wosungunuka zimatha kuyaka, pomwe ulusi wowoneka bwino komanso ulusi wosungunuka kwambiri ndizovuta kuyatsa. Kutentha kwa zomatira kumagwirizana ndi kapangidwe kake ka mankhwala ndi chinyezi.

Chifukwa chiyani ntchitoNsalu zosalukidwa zosagwira motomu mipando yofewa ndi zofunda

Moto wa nyumba zophatikizika ndi mipando, matiresi, ndi zofunda ndizo zomwe zimayambitsa kufa kwa moto, kuvulala, ndi kuwonongeka kwa katundu ku United States, ndipo zitha kuyambitsidwa ndi zinthu zofukizira, moto woyaka, kapena zoyatsira zina. Njira yosalekeza imaphatikizapo kuumitsa zinthu zomwe ogula amazimitsa okha, kuwongolera kukana kwawo moto pogwiritsa ntchito zida ndi zida.
Nthawi zambiri amatchulidwa kuti "zokongoletsa" monga: 1) mipando yofewa, 2) matiresi ndi zofunda, ndi 3) zofunda (zofunda), kuphatikizapo mapilo, mabulangete, matiresi, ndi zinthu zina zofananira Muzinthu izi, m'pofunika kugwiritsa ntchito nsalu zosagwira moto zomwe sizingawombedwe zomwe zimakwaniritsa zofunikira za makasitomala.

Njira yochizira yoletsa moto pansalu yopanda nsalu

Pofuna kukonza kukana kwa moto kwa nsalu zopanda nsalu, zimatha kuthandizidwa ndi moto woletsa moto. Zomwe zimagwiritsidwa ntchito pamoto zimaphatikizapo aluminium phosphate, flame retardant fibers, etc. Zomwe zimawotcha moto zimatha kuwonjezera kukana kwa moto kwa nsalu zopanda nsalu, kuchepetsa kapena kulepheretsa kupanga mpweya woipa ndi magwero a kuyaka panthawi yoyaka.

Miyezo yoyesera yansalu zosawomba zamoto zoletsa moto

Flame retardant yosalukidwa nsalu imatanthawuza zinthu zomwe zingachepetse kapena kulepheretsa kupitiriza ndi kufalikira kwa magwero amoto pamlingo wina. Njira zoyezetsa zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi ndi UL94, ASTM D6413, NFPA 701, GB 20286, ndi zina zotero. UL94 ndi njira yowunika yoletsa moto ku United States, yomwe njira yake yoyesera imayang'ana kwambiri momwe zinthu zimagwirira ntchito molunjika, VO2, VB, magawo anayi a VB, V1.

ASTM D6413 ndi njira yoyezera kuyaka kwa compression yomwe imagwiritsidwa ntchito powunika momwe nsalu zimagwirira ntchito zikayatsidwa poyimirira. NFPA 701 ndi mulingo woletsa moto wamoto woperekedwa ndi National Fire Protection Association ku United States, womwe umafotokozera zofunikira pakugwira ntchito kwapang'onopang'ono pakukongoletsa mkati mwa malo ndi zida za mipando. GB 20286 ndiye mulingo wa "Classification and Specification for Flame Retardant Materials" woperekedwa ndi National Standards Committee of China, womwe umayang'anira kwambiri momwe zinthu zimagwirira ntchito pomanga ndi zovala.

Zochitika zogwiritsira ntchito ndi njira zodzitetezeraNsalu yosawombedwa yosagwira moto

Nsalu zosalukidwa ndi flame retardant zimagwiritsidwa ntchito kwambiri m'magawo monga chitetezo chamoto, zomangira, zamkati zamagalimoto, ndege, zotchingira mafakitale, zamagetsi zamagetsi, ndi zina zambiri, ndipo zimakhala ndi ntchito yabwino yokana moto. Kuwongolera kwa kapangidwe kake ndi kapangidwe kazinthu kumakhudza kwambiri magwiridwe ake oletsa moto, ndipo kuyenera kusankhidwa ndikugwiritsidwa ntchito molingana ndi zochitika zosiyanasiyana.
Pakadali pano, mukamagwiritsa ntchito nsalu yotchinga moto yosawomba, njira zotsatirazi ziyenera kutsatiridwa:

1. Khalani owuma. Pewani chinyezi ndi chinyezi kuti zisakhudze kuchedwa kwamoto.

2. Samalirani kapewedwe ka tizilombo posunga. Mankhwala oletsa tizilombo sayenera kugwiritsidwa ntchito mwachindunji pansalu zosalukidwa.

3. Pewani kugundana ndi zinthu zakuthwa kapena zakuthwa mukamagwiritsa ntchito kuti zisawonongeke.

4. Sangagwiritsidwe ntchito m'malo otentha kwambiri.

5. Mukamagwiritsa ntchito nsalu yotchinga moto yosawomba, onetsetsani kuti mukutsatira buku lazamankhwala kapena buku lachitetezo.

Mapeto

Mwachidule, monga chinthu chokhala ndi moto wotsutsa kwambiri, kutsata miyezo yoyesera ndi njira zodzitetezera pamoto wosawotcha nsalu zopanda nsalu ndizofunika kwambiri kuti zitsimikizidwe kuti zikugwira ntchito. Panthawi imodzimodziyo, ndikofunikira kupanga zisankho zoyenera ndikugwiritsa ntchito pazochitika zinazake.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
