Monga wopanga ndi zaka zopitilira 20 za kafukufuku ndi chitukuko, kupanga ndi kugulitsa magulu akuluakulu amakono aamuna ndi aakazi. Amass ili ndi mitundu yopitilira 100 yazinthu zolumikizidwa, zomwe zimagwiritsidwa ntchito kwambiri pama drones, zida zoyendera, zida zosungira mphamvu, magalimoto amagetsi ndi mafakitale ena.
Zogulitsa zonse zomwe zimayambitsidwa ndi Amass ndizodzipangira zokha komanso zopangidwira, pambuyo pa mayesero ambiri pamsika, khalidwe labwino kwambiri, ntchito yokhazikika, ndipo mankhwala ayesedwa ndi kupopera mchere, pulagi ndi kukoka mphamvu, retardant flame ndi zina zotero! Mu izi, kuwongolera moto ndikofunikira kwambiri, poyang'anizana ndi zochitika zoyaka modzidzimutsa ndi zinthu zina zamagalimoto amagetsi, muyezo watsopano wadziko umanena momveka bwino kuti.cholumikizira mphamvuayenera kukhala ndi ntchito yoletsa moto. Monga katswiri wa zolumikizira zamkati za lithiamu, Amass amakutengerani kuti mumvetsetse kutsekereza kwa mbali zapulasitiki:
Chidule cha Flame Retardant
Flame retardant imatanthawuza kuti pansi pa miyeso yodziwika bwino, chitsanzocho chimatenthedwa, ndipo gwero lamoto litachotsedwa, lawi lamoto limafalikira pa chitsanzocho liri mkati mwa malire ochepa komanso zozimitsa zokha, ndiko kuti, ili ndi mphamvu. kuteteza kapena kuchedwetsa kuchitika kapena kufalikira kwa lawi lamoto.
Mu terminal, retardancy yamoto imatheka powonjezera zinthu zoletsa moto. Flame retardant giredi kuchokera pamwamba mpaka otsika V0, V1, V2 ndi zina zotero. AmassCholumikizira magetsi cha DCZigawo zapulasitiki zogwiritsa ntchito pulasitiki ya PA66, zinthuzo zimagwirizana bwino ndi UL94, V0 retardant flame.
Zida zoteteza moto ndi zida zodzitetezera zomwe zingateteze kuyaka ndipo sizosavuta kuziwotcha zokha, komanso zinthu zomwe zimawotcha moto zimakhala organic ndi inorganic, halogen ndi non-halogen. Organic ndi bromine mndandanda, nayitrogeni mndandanda ndi wofiira phosphorous ndi mankhwala akuimiridwa ndi ena retardants lawi, inorganic ndi makamaka antimony trioxide, magnesium hydroxide, aluminium hydroxide, pakachitsulo ndi machitidwe ena lawi retardant.
Kawirikawiri, organic flame retardants ali ndi ubale wabwino, ndipo bromine retardants amoto amakhala ndi mwayi wochuluka mu organic flame retardants.
Zomwe zimayambira pakuyaka ndi zoyaka, zoyaka komanso zoyatsira. Amakhulupirira kuti kuyaka kwa mapulasitiki kumadutsa njira zitatu monga kulowetsa kutentha - kuwonongeka kwa kutentha - kuyatsa.
Flame retardant mechanism
Kawirikawiri, njira yochepetsera lawi ndikuwonjezera gawo lina lazoletsa moto ku pulasitiki, kuti chiwerengero cha okosijeni chiwonjezeke, motero kumapangitsa kuti moto usawonongeke. Nthawi zambiri, mapulasitiki okhala ndi zoletsa moto akayaka, zoletsa moto zimachita m'njira zambiri m'malo osiyanasiyana. Kwa zipangizo zosiyanasiyana, zotsatira za zoletsa moto zingakhalenso zosiyana.
Njira yochitira zinthu zoletsa moto ndizovuta. Koma cholinga chake nthawi zonse ndikuchotsa kuzungulira kwa kuyaka ndi njira zakuthupi ndi zamankhwala. Zotsatira za ma retardants a flame pa kuyaka zimawonekera m'mbali izi:
1, yomwe ili mu gawo lofupikitsidwa la kuwonongeka kwamoto wamoto, kuti kutentha kwachibale mu gawo lokhazikika kuti muchepetse kukwera kwa kutentha kwapang'onopang'ono kwa pulasitiki, kugwiritsa ntchito kuwonongeka kwamoto komwe kumapangidwa ndi gasification wa gasi wosayaka. kuchepetsa kutentha.
2, retardant yoyaka moto imawonongeka ndi kutentha, kutulutsa chowotcha chamoto chomwe chimagwira -OH (hydroxyl) kwambiri pakuwotcha, kotero kuti njira yoyaka moto molingana ndi mawonekedwe a unyolo waulere imathetsa machitidwe a unyolo.
3, pansi pa kutentha, kutentha kwa moto kumawonekera kusintha kwa gawo la endothermic, kuteteza kuwonjezeka kwa kutentha mu gawo lokhazikika, kotero kuti kuyaka kumachepetsedwa mpaka kuyima.
4, yambitsani kuwonongeka kwa matenthedwe a gawo lopindika, kupanga zinthu zolimba (zophika) kapena wosanjikiza wa thovu, kulepheretsa kutentha. Izi zimapangitsa kuti kutentha kwa gawo la condensed kukhale kochepa, zomwe zimapangitsa kuti mapangidwe achepetseke ngati gawo la gasi lomwe limakhalapo (zowonongeka za mpweya woyaka).
Mwachidule, zotsatira za zoletsa moto zimatha kuchepetsa kwambiri liwiro la kuyaka, kapena kupangitsa kuti kuyambitsako kukhale kovuta, kuti akwaniritse cholinga choletsa ndi kuchepetsa ngozi yamoto.
Tanthauzo lobwezeretsa lamoto
Kugwira ntchito moyenera kwa magetsi kumapangitsa kutentha, ndipo pulagi ya DC butt imatha kuloledwa mkati mwa kutentha komwe kwatchulidwa, koma kupitilira kutentha kwapamwamba kungayambitse ngozi yamoto. Kukhalapo kwa zinthu zoletsa moto pamotohigh-current butt plugzitha kupewa kuchitika kwa moto pamlingo wina, kuchepetsa index yowopsa, kusunga magwiridwe antchito adongosolo, ndikuteteza chitetezo cha moyo ndi katundu.
