Zoletsa moto ndizofunikira zowonjezera zomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana, makamaka mapulasitiki, kuti achepetse kuyaka komanso kulimbitsa chitetezo chamoto. Pamene kufunikira kwa zinthu zotetezeka kukuchulukirachulukira, chitukuko ndi kugwiritsa ntchito zoletsa moto zasintha kwambiri. Nkhaniyi ikuyang'ana mitundu yosiyanasiyana ya zoletsa moto zomwe zimagwiritsidwa ntchito kwambiri mu pulasitiki, njira zawo zogwirira ntchito, ndi zotsatira zake zachilengedwe.
Ma halogenated flame retardants ndi ena mwa omwe amagwiritsidwa ntchito kwambiri m'makampani apulasitiki. Mankhwalawa ali ndi bromine kapena klorini ndipo amathandiza kwambiri kusokoneza kuyaka. Akakumana ndi kutentha, amamasula maatomu a halogen omwe amachitira ndi ma free radicals mulawi, kuzimitsa motowo. Zitsanzo zodziwika bwino ndi tetrabromobisphenol A (TBBPA) ndi polybrominated diphenyl ethers (PBDEs). Ngakhale zili zogwira mtima, nkhawa za kulimbikira kwawo kwachilengedwe komanso zoopsa zomwe zingachitike pazaumoyo zapangitsa kuti aziwunika ndikuwongolera.
Zotsalira zamoto zochokera ku phosphorus zikutchuka chifukwa cha mphamvu zawo komanso kuchepa kwa chilengedwe poyerekeza ndi zosankha za halogenated. Mankhwalawa akhoza kugawidwa m'magulu awiri akuluakulu: zogwira ntchito ndi zowonjezera. Zowonongeka zamoto za phosphorous zimalumikizana ndi polima panthawi yopanga, pomwe mitundu yowonjezera imakhala yosakanikirana mkati mwa pulasitiki. Zitsanzo ndi triphenyl phosphate (TPP) ndi ammonium polyphosphate (APP). Amagwira ntchito polimbikitsa mapangidwe a char, omwe amakhala ngati chotchinga kutentha ndi mpweya, motero amachepetsa kuyaka.
Zotsalira zalawi la inorganic, monga aluminiyamu hydroxide ndi magnesium hydroxide, ndizopanda poizoni komanso zowononga chilengedwe. Zinthu zimenezi zimatulutsa nthunzi wamadzi ukatenthedwa, umene umaziziritsa zinthuzo ndi kuchepetsa mpweya woyaka moto. Nthawi zambiri amagwiritsidwa ntchito m'mapulogalamu omwe chitetezo chimakhala chofunikira kwambiri, monga pazida zamagetsi ndi zamagetsi. Ngakhale kuti sagwira ntchito kwambiri pa kutentha kochepa poyerekeza ndi ma halogenated kapena phosphorous-based retardants, mbiri yawo yachitetezo imawapangitsa kukhala osankhidwa bwino m'mapulogalamu ambiri.
Zoletsa zamoto zoziziritsa kukhosi ndizopadera chifukwa zimakula zikatenthedwa, ndikupanga chiwongolero choteteza chomwe chimateteza zinthu zomwe zili pansi pamoto. Mtundu uwu wa retardant lamoto nthawi zambiri umakhala ndi kuphatikiza kwa gwero la kaboni, gwero la asidi, ndi chowombera. Akatenthedwa, gwero la asidi limapangitsa gwero la kaboni kuti likhale lamoto, pamene chowombera chimapanga mpweya wowonjezera wowonjezera. Makinawa amapereka chitetezo chabwino kwambiri pamoto ndipo nthawi zambiri amagwiritsidwa ntchito popaka ndi mapulasitiki osinthika.
Ngakhale zoletsa moto zimagwira ntchito yofunika kwambiri pakulimbikitsa chitetezo chamoto, kugwiritsa ntchito kwawo kumabweretsa zovuta zachilengedwe komanso zaumoyo. Ma halogenated flame retardants ambiri adalumikizidwa ndi zotsatira zoyipa zaumoyo, kuphatikiza kusokonezeka kwa endocrine ndi zovuta zachitukuko. Zotsatira zake, mabungwe owongolera akuletsa kwambiri kugwiritsa ntchito kwawo. Mosiyana ndi zimenezi, phosphorous ndi inorganic flame retardants nthawi zambiri amaonedwa ngati njira zotetezeka, ngakhale kufufuza kosalekeza n'kofunika kuti mumvetse bwino zomwe zidzachitike kwa nthawi yaitali.
Kusankhidwa kwa zoletsa moto m'mapulasitiki kumakhudzidwa ndi zinthu zosiyanasiyana, kuphatikiza mphamvu, chitetezo, komanso kukhudzidwa kwachilengedwe. Pamene malamulo akukhwimitsa komanso kuzindikira kwa ogula kukukulirakulira, makampaniwa akuyenera kupitiliza kusunthira njira zotetezeka, zokhazikika zoletsa moto. Kumvetsetsa mitundu yosiyanasiyana ya zoletsa moto ndi momwe zimagwirira ntchito ndikofunikira kwa opanga, ogula, ndi opanga mfundo pakufuna zida zotetezeka.
Malingaliro a kampani Sichuan Taifeng New Flame Retardant Co., Ltdndi wopanga yemwe ali ndi zaka 22 wokhazikika pakupanga ammonium polyphosphate retardants lamoto, zopangira zathu zimatumizidwa kunja kwina.
Woyimilira wathu wamoto retardantMtengo wa TF-241ndi eco-ochezeka komanso zachuma, ili ndi ntchito yokhwima mu PP, PE, HEDP.
Ngati mukufuna kudziwa zambiri, chonde titumizireni.
