Zinthu zoletsa moto ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito mu zipangizo zosiyanasiyana, makamaka mapulasitiki, kuti zichepetse kuyaka komanso kulimbitsa chitetezo cha moto. Pamene kufunikira kwa zinthu zotetezeka kukuchulukirachulukira, kupanga ndi kugwiritsa ntchito zinthu zoletsa moto kwasintha kwambiri. Nkhaniyi ikufotokoza mitundu yosiyanasiyana ya zinthu zoletsa moto zomwe zimagwiritsidwa ntchito kwambiri mu mapulasitiki, njira zawo zogwirira ntchito, komanso momwe zimakhudzira chilengedwe.
Zinthu zoletsa moto zomwe zili ndi halogenated ndi zina mwa zinthu zomwe zimagwiritsidwa ntchito kwambiri mumakampani opanga mapulasitiki. Mankhwalawa ali ndi bromine kapena chlorine ndipo amagwira ntchito bwino poletsa kuyaka. Akayikidwa pamoto, amatulutsa maatomu a halogen omwe amachitapo kanthu ndi ma free radicals omwe ali mumoto, zomwe zimathandiza kuzimitsa motowo. Zitsanzo zodziwika bwino ndi monga tetrabromobisphenol A (TBBPA) ndi polybrominated diphenyl ethers (PBDEs). Ngakhale kuti ndi othandiza, nkhawa zokhudzana ndi kupirira kwawo kwachilengedwe komanso zoopsa zomwe zingachitike pa thanzi zapangitsa kuti pakhale kufufuza ndi malamulo ambiri.
Zinthu zoletsa moto zochokera ku phosphorous zikutchuka chifukwa cha kugwira ntchito kwawo bwino komanso kuchepa kwa mphamvu zachilengedwe poyerekeza ndi zinthu zopangidwa ndi halogenated. Mankhwalawa akhoza kugawidwa m'magulu awiri akuluakulu: reactive ndi adjuvant. Zinthu zoletsa moto za phosphorous zomwe zimagwira ntchito zimalumikizana ndi polymer panthawi yopanga, pomwe mitundu yowonjezera imakhalabe yosakanikirana mkati mwa pulasitiki. Zitsanzo zikuphatikizapo triphenyl phosphate (TPP) ndi ammonium polyphosphate (APP). Zimagwira ntchito polimbikitsa kupanga kwa char, komwe kumagwira ntchito ngati chotchinga kutentha ndi mpweya, motero kuchepetsa kuyaka.
Zinthu zoletsa moto zosapangidwa ndi organic, monga aluminiyamu hydroxide ndi magnesium hydroxide, ndi zinthu zina zopanda poizoni komanso zosawononga chilengedwe. Zinthuzi zimatulutsa nthunzi ya madzi zikatenthedwa, zomwe zimaziziritsa zinthuzo ndikuchepetsa mpweya woyaka. Nthawi zambiri zimagwiritsidwa ntchito m'malo omwe chitetezo chili chofunika kwambiri, monga m'zida zamagetsi ndi zamagetsi. Ngakhale sizigwira ntchito bwino pa kutentha kochepa poyerekeza ndi zinthu zoletsa moto zokhala ndi halogenated kapena phosphorous, chitetezo chawo chimawapangitsa kukhala chisankho chabwino kwambiri m'malo ambiri.
Zinthu zoletsa moto zomwe zimalowa m'thupi zimakhala zapadera chifukwa zimakula zikamatenthedwa, zomwe zimapangitsa kuti zinthu zomwe zili pansi pake zisatenthedwe. Mtundu uwu wa zinthu zoletsa moto nthawi zambiri umakhala ndi kuphatikiza kwa gwero la kaboni, gwero la asidi, ndi chinthu chopukutira. Zikatenthedwa, gwero la asidi limayambitsa gwero la kaboni kuti lipange char, pomwe chinthu chopukutira chimapanga thovu la mpweya lomwe limakulitsa gawo la char. Njirayi imapereka chitetezo chabwino kwambiri pamoto ndipo nthawi zambiri imagwiritsidwa ntchito popanga zokutira ndi mapulasitiki osinthasintha.
Ngakhale kuti zinthu zoletsa moto zimathandiza kwambiri pakulimbitsa chitetezo cha moto, kugwiritsa ntchito kwake kumabweretsa mavuto aakulu pa chilengedwe ndi thanzi. Zinthu zambiri zoletsa moto zokhala ndi halogenated zakhala zikugwirizanitsidwa ndi zotsatirapo zoipa pa thanzi, kuphatikizapo kusokonezeka kwa endocrine ndi mavuto a chitukuko. Chifukwa chake, mabungwe olamulira akuchepetsa kugwiritsa ntchito zinthuzi. Mosiyana ndi zimenezi, zinthu zoletsa moto zopangidwa ndi phosphorous ndi zinthu zina zosapangidwa ndi organic nthawi zambiri zimaonedwa kuti ndi njira zina zotetezeka, ngakhale kuti kafukufuku wopitilira ndi wofunikira kuti timvetse bwino zotsatira zake kwa nthawi yayitali.
Kusankha zinthu zoletsa moto mu pulasitiki kumakhudzidwa ndi zinthu zosiyanasiyana, kuphatikizapo kugwira ntchito bwino, chitetezo, komanso momwe chilengedwe chimakhudzira. Pamene malamulo akuchulukirachulukira komanso chidziwitso cha ogula chikukula, makampaniwa akuyembekezeka kupitiriza kusinthira ku njira zotetezeka komanso zokhazikika zoletsa moto. Kumvetsetsa mitundu yosiyanasiyana ya zinthu zoletsa moto ndi njira zake ndikofunikira kwa opanga, ogula, ndi opanga mfundo pofunafuna zinthu zotetezeka.
Sichuan Taifeng New Flame Retardant Co., Ltdndi wopanga yemwe ali ndi zaka 22 zakuchitikira popanga zinthu zoletsa moto za ammonium polyphosphate, ndipo zinthu zathu zodzitamandira zimatumizidwa kunja kwambiri.
Woyimira wathu woletsa motoTF-241Ndi yochezeka komanso yotsika mtengo, imagwiritsidwa ntchito bwino mu PP, PE, ndi HEDP.
Ngati mukufuna kudziwa zambiri, chonde titumizireni uthenga.
