I-agent ye-toughening ibhekisela kwinto enokunyusa ukuguquguquka kwefilimu yokunamathela.Ezinye izincamathelisi ze-resin ze-thermosetting, ezifana ne-epoxy resin, i-phenolic resin kunye ne-unsaturated polyester resin adhesives emva kokunyanga, ukunyuka okuphantsi, ubuthathaka obukhulu, xa indawo yokudibanisa phantsi kwamandla angaphandle kulula ukuqhekeka, kunye nokwandiswa ngokukhawuleza, okukhokelela ekuqhekekeni, ukuxhathisa ukukhathala, ingasetyenziswa njengeqhina lolwakhiwo.Ngoko ke, kuyimfuneko ukunciphisa i-brittleness, ukwandisa ukuqina kunye nokuphucula amandla okuthwala.Izinto eziphathekayo ezinokunciphisa i-brittleness kunye nokwandisa ukuqina ngaphandle kokuchaphazela ezinye iimpawu eziphambili ze-adhesive yi-agent agent.Inokwahlulwa ibe yi-agent eqinisa irabha kunye ne-thermoplastic elastomer agent toughening.

Intshayelelo yemveliso kunye neempawu

1
(2) thermoplastic elastomer Thermoplastic elastomer luhlobo lwemathiriyeli eyenziweyo ebonisa ukunwebeka kwerabha kubushushu begumbi kwaye inokufakwa iplastiki kubushushu obuphezulu.Ke ngoko, olu hlobo lwepolymer luneempawu zazo zombini irabha kunye ne-thermoplastic, inokusetyenziswa njenge-ejenti eqinisayo yezinto ezidibeneyo, kwaye ingasetyenziswa njengesixhobo sematrix sezinto ezihlanganisiweyo.Olu hlobo lwemathiriyeli ikakhulu lubandakanya i-polyurethane, i-styrene, i-polyolefin, i-polyester, i-interregular 1, i-2-polybutadiene kunye ne-polyamides kunye nezinye iimveliso, ngoku njenge-agent enzima yezinto ezidibeneyo ezisetyenziselwa i-styrene kunye ne-polyolefin.
(3) Ezinye ii-agent eziqinisayo Ezinye ii-agent eziqinisayo ezifanelekileyo kwii-composites zi-polyamides ezinobunzima obuphantsi bemolekyuli kunye ne-molecular weight low inactive toughening agents, njenge-phthalate esters.I-ejenti yokuqina engasebenziyo nayo ingabizwa ngokuba yi-plasticizer, engathathi nxaxheba ekuphenduleni ukunyanga kwe-resin.

sebenzisa

I-ejenti yokuqina ifanelekile kwi-adhesives, i-rubber, i-coatings kunye nezinye iimveliso.Luhlobo lwe-agent encedisayo enokunciphisa ukunyanzeliswa kwezinto ezidibeneyo kunye nokuphucula ukuchasana kwempembelelo yezinto ezidibeneyo.Inokwahlulwa ibe yi-agent esebenzayo kunye ne-ejenti yokuqina engasebenziyo.I-agent esebenzayo ye-toughening ibhekisela kwikhonkco yayo ye-molecular equkethe amaqela asebenzayo anokuthi asebenze kunye ne-matrix resin, enokuthi yenze isakhiwo sothungelwano, yongeza inxalenye yekhonkco eguquguqukayo, kwaye ngaloo ndlela iphucula ukuchasana kwempembelelo yezinto ezidibeneyo.I-arhente yokuqina engasebenziyo luhlobo lwe-agent eqinisayo enyibilika nge-matrix resin kodwa ayithathi nxaxheba kwi-chemical reaction.

iphakheji kunye nezithuthi

B. Le mveliso ingasetyenziswa,, 25KG, BAERRLS.
C. Gcina uvalelwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi.Imigqomo kufuneka ivalwe ngokuqinileyo emva kokusetyenziswa ngakunye phambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthutha ukukhusela umswakama, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ekuxubeni.
