Momwe mungasinthire kufalikira kwa zoletsa moto

Pogwiritsa ntchito kwambiri zida za polima ndi zinthu zogula pamagetsi pa moyo watsiku ndi tsiku, kuchuluka kwa moto kukuchulukiranso, ndipo kuvulaza komwe kumabweretsa kumakhala kowopsa kwambiri. Kugwira ntchito koletsa moto kwa zida za polima kwakhala kofunika kwambiri, ndicholinga chokwaniritsa zofunikira zamapulasitiki ndi mphira, kuchepetsa kuipitsidwa kwafumbi komwe kumayambitsidwa ndi zoletsa moto, masterbatch yobwezeretsa lawi idayamba, ndipo imasewera yofunika kwambiri. ndi udindo wofunikira pakuumba zinthu zomaliza.

Flame retardant masterbatch amapangidwa molingana ndi chilinganizo chololera, kudzera mu kuphatikiza kwachilengedwe kwa flame retardant, lubricant dispersant ndi chonyamulira, kudzera pakuyenga wandiweyani, kusanganikirana, kufanana ndiyeno extrusion granulation. Mu ichi, dispersant amagwira ntchito yofunika kwambiri, kuwonjezera gawo lina la dispersant zingakhale zabwino kwambiri kulimbikitsa kubalalitsidwa wa retardant lawi, kotero kuti n'zosavuta wogawana omwazika mu ndondomeko, kuteteza agglomeration wa retardant lawi, ndi bwino dispersing tingati kuti lawi retardant mamolekyulu kusewera bwino lawi retardant kwenikweni, potero kuwongolera lawi retardant dzuwa la pulasitiki, mankhwala mphira, moto adzakhala pakhosi pa siteji oyambirira.

Komabe, muzochita, mapulasitiki ambiri ndi ziwalo za mphira zomwe zili ndi zigawo zomwe zimawotcha moto sizingathe kuchita zinthu zomwe zimawotcha moto chifukwa cha kufalikira kosagwirizana kwa moto wamoto muzinthu zomwe zimayaka moto, zomwe zimabweretsa moto wokulirapo komanso kutayika kwakukulu.

Pofuna kulimbikitsa kubalalitsidwa yunifolomu wa retardants lawi kapena lawi retardant masterbatch mu ndondomeko akamaumba mankhwala, kuchepetsa kuchitika kwa kubalalikana chifukwa cha lawi retardant zotsatira sangathe efficiently exerted, etc., ndi kusintha khalidwe lamoto retardant mankhwala, SILIKE yapanga chowonjezera cha silicone SILIMER hyperdispersant.

SILIMER ndi mtundu wa tri-block copolymerized modified siloxane yopangidwa ndi ma polysiloxanes, magulu a polar ndi magulu aatali a carbon. Magawo a unyolo wa polysiloxane amatha kukhala ndi gawo lina lodzipatula pakati pa mamolekyu oyaka moto pansi pa kukameta ubweya wamakina, kuletsa kuphatikizika kwachiwiri kwa mamolekyu oletsa moto; zigawo zamagulu a polar zimakhala ndi mgwirizano wina ndi wolepheretsa moto, zomwe zimagwira ntchito yolumikizana; zigawo zazitali za carbon chain zimakhala ndi mgwirizano wabwino kwambiri ndi zinthu zoyambira.

Mndandanda wazinthuzi ndizoyenera ma resins wamba a thermoplastic, TPE, TPU ndi ma elastomer ena a thermoplastic, ndipo amatha kupititsa patsogolo kugwirizana pakati pa ma inki/filler powders/functional powders and resin systems, ndikusunga kuti kubalalitsidwa kwa ufa kukhale kokhazikika.

Pa nthawi yomweyo, akhoza kuchepetsa mamasukidwe akayendedwe a Sungunulani, kuchepetsa makokedwe a extruder, kuthamanga extrusion, kusintha ntchito processing wa zinthu, ndi mafuta processing wabwino, ndipo nthawi yomweyo akhoza bwino kusintha kumverera kwa pamwamba pa zinthu, ndi mlingo wina wa kusalala ndi sikumakhudza mawotchi katundu wa zinthu, ndi kulimbikitsa yunifolomu kubalalitsidwa kwa zigawo lawi-retardant kulimbikitsa lawi retardant zotsatira za mankhwala chomaliza kupereka sewero lonse kwa mkulu. -mayankho abwino.

Kuphatikiza apo, mndandanda wazinthuzi siwoyenera kokha kwa masterbatch yobwezeretsa moto, komanso mtundu wa masterbatch kapena zida zapamwamba zomwazikana.
