cholimba
makhalidwe a mankhwala
Chogwirizira cholimba chimatanthauza chinthu chomwe chingawonjezere kusinthasintha kwa filimu yomatira. Ma thermosetting resin glues ena, monga epoxy resin, phenolic resin ndi unsaturated polyester resin glues atatha kukonzedwa, kutalikirana pang'ono, kufooka kwakukulu, pamene malo omatira pansi pa mphamvu yakunja ndi osavuta kusweka, ndipo kukula mwachangu, zomwe zimapangitsa kuti ming'alu, kukana kutopa, sikungagwiritsidwe ntchito ngati chogwirizira chomangira. Chifukwa chake, ndikofunikira kuchepetsa kufooka, kuwonjezera kulimba ndikuwonjezera mphamvu ya bere. Zinthu zomwe zingachepetse kufooka ndikuwonjezera kulimba popanda kukhudza makhalidwe ena akuluakulu a guluu ndi chogwirizira cholimba. Chingagawidwe m'magulu awiri: chogwirizira cholimba cha rabara ndi chogwirizira cholimba cha thermoplastic elastomer.
Chiyambi cha malonda ndi zinthu zake
(1) Mitundu ya mankhwala omatira a rabara monga rabara yamadzimadzi ya polysulfide, rabara yamadzimadzi ya acrylic, rabara yamadzimadzi ya polybutadiene, rabara ya nitrile, rabara ya ethylene propylene ndi rabara ya styrene butadiene, ndi zina zotero.
(2) thermoplastic elastomer Thermoplastic elastomer ndi mtundu wa zinthu zopangidwa zomwe zimasonyeza kusinthasintha kwa rabara kutentha kwa chipinda ndipo zimatha kupangidwa pulasitiki kutentha kwambiri. Chifukwa chake, mtundu uwu wa polima uli ndi makhalidwe a rabara ndi thermoplastic, ungagwiritsidwe ntchito ngati chogwirizira chogwirizira zinthu zophatikizika, ndipo ungagwiritsidwe ntchito ngati matrix ya zinthu zophatikizika. Mtundu uwu wa zinthu umaphatikizapo makamaka polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene ndi polyamides ndi zinthu zina, pakadali pano ngati chogwirizira chogwirizira zinthu zophatikizika chimagwiritsidwa ntchito kwambiri ndi styrene ndi polyolefin.
(3) Zinthu zina zolimbitsa thupi Zinthu zina zolimbitsa thupi zoyenera kugwiritsidwa ntchito ndi ma polyamides otsika kulemera kwa mamolekyulu ndi zinthu zochepa zolimbitsa thupi zosagwira ntchito, monga ma phthalate esters. Chinthu cholimbitsa thupi chosagwira ntchito chingatchedwenso kuti plasticizer, chomwe sichichita nawo mu resin yomwe imachiritsa.
gwiritsani ntchito
Chogwirizira chogwira ntchito ndi choyenera kugwiritsa ntchito zomatira, rabara, zokutira ndi zinthu zina. Ndi mtundu wa chogwirizira chomwe chingachepetse kufooka kwa zinthu zophatikizika ndikuwonjezera kukana kwa zinthu zophatikizika. Chingagawidwe m'magulu awiri: chogwirizira chogwira ntchito komanso chogwirizira chogwira ntchito. Chogwirizira chogwira ntchito chimatanthauza unyolo wake wa mamolekyu womwe uli ndi magulu ogwira ntchito omwe amatha kuchitapo kanthu ndi utomoni wa matrix, womwe ungapange kapangidwe ka netiweki, kuwonjezera gawo la unyolo wosinthasintha, motero kumawonjezera kukana kwa zinthu zophatikizika. Chogwirizira chogwira ntchito chogwira ntchito ndi mtundu wa chogwirizira chogwira ntchito chomwe chimasungunuka ndi utomoni wa matrix koma sichichita nawo machitidwe a mankhwala.
phukusi ndi mayendedwe
B. Chogulitsachi chingagwiritsidwe ntchito,,25KG，BAERRLS。
C. Sungani yotsekedwa m'nyumba pamalo ozizira, ouma komanso opumira mpweya. Zidebe ziyenera kutsekedwa bwino mukatha kugwiritsa ntchito nthawi iliyonse musanagwiritse ntchito.
D. Chogulitsachi chiyenera kutsekedwa bwino panthawi yonyamula kuti chisasakanikirane ndi chinyezi, alkali ndi asidi wamphamvu, mvula ndi zinyalala zina.
