Momwe mungakulitsire kufalikira kwa zinthu zoletsa moto

Chifukwa cha kugwiritsa ntchito kwambiri zinthu za polima ndi zinthu zamagetsi zomwe zimagwiritsidwa ntchito tsiku ndi tsiku, kuchuluka kwa moto kukuchulukirachulukira, ndipo kuvulaza komwe kumabweretsa kukuopsa kwambiri. Kugwira ntchito kwa zinthu za polima zomwe zimaletsa moto kwakhala kofunika kwambiri, chifukwa chake ndi cholinga chokwaniritsa zofunikira za zinthu za pulasitiki ndi rabara zomwe zimaletsa moto, kuchepetsa kuipitsa kwa fumbi komwe kumachitika chifukwa cha zinthu zoletsa moto, masterbatch yomwe imaletsa moto idayamba, ndipo imagwira ntchito yofunika kwambiri popanga zinthu zomaliza.

Masterbatch yoletsa moto imapangidwa motsatira njira yoyenera, kudzera mu kuphatikiza kwachilengedwe kwa choletsa moto, chotsitsa mafuta ndi chonyamulira, kudzera mu kuyenga kwambiri, kusakaniza, kufanana kenako ndi extrusion granulation. Pankhaniyi, chotsitsa chimagwira ntchito yofunika kwambiri, kuwonjezera gawo lina la chotsitsa moto kungakhale bwino kwambiri kuti chilimbikitse kufalikira kwa choletsa moto, kotero kuti zikhale zosavuta kufalikira mofanana panthawiyi, kuti zisawonongeke, komanso kuti chisakanizo cha choletsa moto chikhale bwino, kuti mamolekyu oletsa moto azisewera bwino, motero kukonza bwino ntchito ya pulasitiki, zinthu za rabara, moto udzaphwanyidwa pachiyambi.

Komabe, m'machitidwe, mapulasitiki ambiri ndi zida za rabara zomwe zili ndi zida zoletsa moto sizingathe kuchita zinthu zomwe zimaletsa moto chifukwa cha kufalikira kosagwirizana kwa zinthu zomwe zimaletsa moto zomwe zili mu chipangizocho pamoto, zomwe zimapangitsa kuti pakhale moto waukulu komanso kutayika kwakukulu.

Pofuna kulimbikitsa kufalikira kwa zinthu zoletsa moto kapena masterbatch yoletsa moto mu njira yopangira zinthu, kuchepetsa kupezeka kwa zinthu zosagwirizana chifukwa cha mphamvu yoletsa moto yomwe singagwiritsidwe ntchito bwino, ndi zina zotero, ndikukweza ubwino wa zinthu zoletsa moto, SILIKE yapanga chowonjezera cha silicone chosinthidwa cha SILIMER hyperdispersant.

SILIMER ndi mtundu wa siloxane yosinthidwa yokhala ndi ma polysiloxanes, magulu a polar ndi magulu a unyolo wautali wa kaboni. Magawo a unyolo wa polysiloxane amatha kukhala ndi gawo linalake pakati pa mamolekyulu oletsa moto pansi pa makina odulira, kuletsa kusonkhana kwachiwiri kwa mamolekyulu oletsa moto; magawo a unyolo wa gulu la polar ali ndi mgwirizano ndi choletsa moto, zomwe zimagwira ntchito yolumikizana; magawo a unyolo wautali wa kaboni ali ndi mgwirizano wabwino kwambiri ndi zinthu zoyambira.

Zogulitsazi ndizoyenera ma resins wamba a thermoplastic, TPE, TPU ndi ma elastomers ena a thermoplastic, ndipo zimatha kusintha kugwirizana pakati pa utoto/ufa wodzaza/ufa wogwira ntchito ndi machitidwe a resins, ndikusunga mkhalidwe wofalikira wa ufawo kukhala wokhazikika.

Nthawi yomweyo, imathanso kuchepetsa kukhuthala kwa kusungunuka, kuchepetsa mphamvu ya extruder, kuthamanga kwa extrusion, kusintha magwiridwe antchito a zinthuzo, ndi mafuta abwino opangira, komanso nthawi yomweyo imatha kusintha bwino momwe zinthuzo zimamvekera, komanso sizikhudza mawonekedwe a makina a zinthuzo, komanso zimapangitsa kuti zinthuzo zisamayende bwino, komanso zimapangitsa kuti zinthuzo zisamayende bwino, komanso kuti zinthuzo zisamayende bwino.

Kuphatikiza apo, mndandanda wazinthuzi sizoyenera kokha pa masterbatch yoletsa moto, komanso pa masterbatch yamitundu kapena zinthu zomwe zimabalalitsidwa kale.
