Toughening wothandizira amatanthauza chinthu chomwe chingawonjezere kusinthasintha kwa filimu yomatira.Ena thermosetting utomoni zomatira, monga epoxy utomoni, phenolic utomoni ndi unsaturated polyester utomoni zomatira pambuyo kuchiritsa, otsika elongation, fragility kwambiri, pamene malo omangirira pansi mphamvu yakunja ndi yosavuta kusweka, ndi kukula mofulumira, kuchititsa ang'onoang'ono, kukana kutopa, akhoza. osagwiritsidwa ntchito ngati mgwirizano wamagulu.Choncho, m'pofunika kuchepetsa brittleness, kuonjezera kulimba ndi kupititsa patsogolo mphamvu yobereka.Zinthu zomwe zimatha kuchepetsa brittleness ndikuwonjezera kulimba popanda kukhudza zinthu zina zazikulu zomatira ndizothandizira toughening.Itha kugawidwa mu mphira toughening agent ndi thermoplastic elastomer toughening agent.
Chiyambi cha malonda ndi mawonekedwe ake
(1) Mpira toughening wothandizila mtundu wa toughening wothandizira mitundu makamaka monga madzi polysulfide mphira, madzi akiliriki mphira, madzi polybutadiene mphira, nitrile mphira, ethylene propylene mphira ndi styrene butadiene mphira, etc.
(2) thermoplastic elastomer Thermoplastic elastomer ndi mtundu wa zinthu zopangira zomwe zimasonyeza kusungunuka kwa mphira kutentha kwa firiji ndipo kumatha kupangidwa ndi pulasitiki pa kutentha kwakukulu.Chifukwa chake, polima wamtunduwu ali ndi mawonekedwe a mphira ndi thermoplastic, atha kugwiritsidwa ntchito ngati chowongolera chazinthu zophatikizika, ndipo angagwiritsidwe ntchito ngati matrix azinthu zophatikizika.Mtundu wa zinthu makamaka zikuphatikizapo polyurethane, styrene, polyolefin, poliyesitala, interregular 1, 2-polybutadiene ndi polyamides ndi zinthu zina, panopa monga toughening wothandizila wa zipangizo gulu ntchito kwambiri styrene ndi polyolefin.
(3) Zida zina zolimbitsa thupi Zina zolimbitsa thupi zomwe zimayenera kuphatikiziridwa ndi ma polyamide ochepera a molekyulu olemera kwambiri ndi ma cell ang'onoang'ono osagwira ntchito zolimbitsa thupi, monga phthalate esters.Katundu wosagwira ntchito amathanso kutchedwa plasticizer, yemwe satenga nawo gawo pakuchiritsa kwa utomoni.
ntchito
The toughening wothandizira ndi oyenera zomatira, mphira, zokutira ndi zinthu zina.Ndi mtundu wothandizira wothandizira womwe ungachepetse kuwonongeka kwa zinthu zophatikizika ndikuwongolera kukana kwazinthu zophatikizika.Iwo akhoza kugawidwa mu yogwira toughening wothandizila ndi anafooka toughening wothandizira.Active toughening wothandizila amatanthauza unyolo wa maselo omwe ali ndi magulu omwe amagwira ntchito omwe amatha kuchitapo kanthu ndi utomoni wa masanjidwewo, omwe amatha kupanga maukonde, kuwonjezera gawo la unyolo wosinthika, motero amawongolera kukana kwazinthu zophatikizika.Inactive toughening agent ndi mtundu wa chinthu cholimbitsa chomwe chimasungunuka ndi matrix resin koma sichitenga nawo gawo pakuchita mankhwala.
phukusi ndi transport
B. Izi zitha kugwiritsidwa ntchito,, 25KG, BAERRLS.
C. Sungani chosindikizidwa mu malo ozizira, owuma ndi mpweya wokwanira m'nyumba.Zotengera ziyenera kutsekedwa mwamphamvu mukatha kugwiritsa ntchito chilichonse musanagwiritse ntchito.
D. Mankhwalawa ayenera kusindikizidwa bwino panthawi yoyendetsa kuti ateteze chinyezi, alkali wamphamvu ndi asidi, mvula ndi zonyansa zina kuti zisasakanike.
