toughener
litšobotsi tsa lik'hemik'hale
Toughening agent e bolela ntho e ka eketsang ho feto-fetoha ha filimi ea sekhomaretsi.Likhomaretsi tse ling tsa thermosetting resin, tse kang epoxy resin, phenolic resin le unsaturated polyester resin adhesives ka mor'a ho folisa, elongation e tlaase, fragility e kholoanyane, ha sebaka sa ho tlama se ka tlas'a matla a ka ntle ho bonolo ho phunyeha, le ho atoloha ka potlako, ho fella ka ho phatloha, ho hanyetsa mokhathala. e se sebedisoe joalo ka tlamahano ya sebopeho.Ka hona, hoa hlokahala ho fokotsa brittleness, ho eketsa ho tiea le ho ntlafatsa matla a ho jara.Thepa e ka fokotsang brittleness le ho eketsa ho tiea ntle le ho ama thepa e 'ngoe e ka sehloohong ea sekhomaretsi ke moemeli oa toughening.E ka aroloa ka rabara toughening agent le thermoplastic elastomer toughening agent.
Kenyelletso ea sehlahisoa le likarolo
(1) Rabara toughening agent mofuta ona oa mofuta o toughening agent haholo-holo e kenyelletsa rabara ea metsi ea polysulfide, rabara ea metsi ea acrylic, rabara ea polybutadiene ea metsi, rabara ea nitrile, rabara ea ethylene propylene le rabara ea styrene butadiene, joalo-joalo.
(2) thermoplastic elastomer Thermoplastic elastomer ke mofuta oa thepa ea maiketsetso e bontšang elasticity ea rabara mochesong oa kamore 'me e ka etsoa polasetiki ka mocheso o phahameng.Ka hona, mofuta ona oa polymer o na le litšobotsi tsa rabara le thermoplastic, e ka sebelisoa e le ntho e thatafatsang ea thepa e kopaneng, 'me e ka sebelisoa e le thepa ea matrix ea thepa e kopaneng.Mofuta ona oa thepa haholo-holo o kenyelletsa polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene le polyamides le lihlahisoa tse ling, hona joale e le moemeli ea toughening ea lisebelisoa tse kopantsoeng tse sebelisoang ho feta styrene le polyolefin.
(3) Lintho tse ling tse toughening Lisebelisoa tse ling tse toughening tse loketseng metsoako ke polyamides ea boima ba molek'hule e tlaase le limolek'hule tse sa sebetseng tse toughening tse kang phthalate esters.Ntho e sa sebetseng ea ho toughening e ka boela ea bitsoa plasticizer, e sa kopaneleng karabelong ea ho folisa ea resin.
tshebediso
Setsi sa toughening se loketse li-adhesives, rabara, liaparo le lihlahisoa tse ling.Ke mofuta oa moemeli ea thusang o ka fokotsang brittleness ea lisebelisoa tse kopantsoeng le ho ntlafatsa ho hanyetsa ha thepa ea thepa e kopantsoeng.E ka aroloa ka agent e sebetsang ea toughening le e sa sebetseng ea toughening agent.Active toughening agent e bua ka ketane ea eona ea limolek'hule e nang le lihlopha tse sebetsang tse ka sebetsanang le resin ea matrix, e ka etsang sebopeho sa marang-rang, ea eketsa karolo ea ketane e feto-fetohang, 'me kahoo e ntlafatsa ho hanyetsa tšusumetso ea thepa e kopantsoeng.Inactive toughening agent ke mofuta oa ntho e thatafatsang e qhibilihang ka matrix resin empa e sa kenelle tšebetsong ea lik'hemik'hale.
sephutheloana le sepalangoang
B. Sehlahisoa sena se ka sebelisoa,, 25KG, BAERRLS.
C. Boloka e tiisitsoe sebakeng se phodileng, se omeletseng le se nang le moea o kenang ka tlung.Lijana li lokela ho koaloa ka thata ka mor'a tšebeliso e 'ngoe le e' ngoe pele li sebelisoa.
D. Sehlahisoa sena se lokela ho koaloa hantle nakong ea lipalangoang ho thibela mongobo, alkali e matla le acid, pula le litšila tse ling ho tsoaka.
