iimpawu zeekhemikhali
I-arhente yokuqinisa ibhekisa kwinto enokunyusa ukuguquguquka kwefilimu yokuncamathelisa. Ezinye izincamathelisi ze-resin ezisetyenziswa kwi-thermosetting, ezifana ne-epoxy resin, i-phenolic resin kunye ne-polyester resin adhesives emva kokulungiswa, ukwandiswa okuphantsi, ubuthathaka obukhulu, xa indawo yokunamathela phantsi kwamandla angaphandle kulula ukuyiqhekeza, kwaye ukwanda ngokukhawuleza, okubangela ukuqhekeka, ukumelana nokudinwa, akunakusetyenziswa njenge-structural bonding. Ke ngoko, kuyimfuneko ukunciphisa ubuthathaka, ukwandisa ukuqina kunye nokuphucula amandla okuthwala. Izinto ezinokunciphisa ubuthathaka kunye nokwandisa ukuqina ngaphandle kokuchaphazela ezinye iimpawu eziphambili ze-adhesive yi-arhente yokuqinisa. Ingahlulwa ibe yi-arhente yokuqinisa irabha kunye ne-arhente yokuqinisa i-thermoplastic elastomer
Intshayelelo yemveliso kunye neempawu zayo
(1) I-arhente yokuqinisa irabha olu hlobo lwee-arhente zokuqinisa luquka ikakhulu irabha ye-polysulfide engamanzi, irabha ye-acrylic engamanzi, irabha ye-polybutadiene engamanzi, irabha ye-nitrile, irabha ye-ethylene propylene kunye nerabha ye-styrene butadiene, njl.
(2) i-thermoplastic elastomer I-thermoplastic elastomer luhlobo lwezinto ezenziwe ngokwenziwa ezibonisa ukuthamba kwerabha kubushushu begumbi kwaye zinokwenziwa iplastiki kubushushu obuphezulu. Ke ngoko, olu hlobo lwepolymer luneempawu zerabha kunye ne-thermoplastic, lungasetyenziswa njenge-arhente yokuqinisa izinto ezidityanisiweyo, kwaye lungasetyenziswa njengezinto ze-matrix zezinto ezidityanisiweyo. Olu hlobo lwezinto luquka ikakhulu i-polyurethane, i-styrene, i-polyolefin, i-polyester, i-interregular 1, i-2-polybutadiene kunye ne-polyamides kunye nezinye iimveliso, okwangoku njenge-arhente yokuqinisa izinto ezidityanisiweyo ezisetyenziswa ngakumbi yi-styrene kunye ne-polyolefin.
(3) Ezinye izinto zokuqinisa Ezinye izinto zokuqinisa ezifanelekileyo kwii-composites zii-polyamides ezinobunzima obuphantsi beemolekyuli kunye nee-arhente zokuqinisa ezingasebenziyo ezinobunzima obuphantsi beemolekyuli, ezifana nee-esters ze-phthalate. I-arhente yokuqinisa engasebenziyo ingabizwa ngokuba yi-plasticizer, engathathi nxaxheba kwi-resin ephilisayo.
sebenzisa
I-arhente yokuqinisa ifanelekile kwizincamathelisi, irabha, iingubo kunye nezinye iimveliso. Luhlobo lwe-arhente encedisayo enokunciphisa ubulukhuni bezinto ezidityanisiweyo kwaye iphucule ukumelana nempembelelo yezinto ezidityanisiweyo. Ingahlulwa ibe yi-arhente yokuqinisa esebenzayo kunye ne-arhente yokuqinisa engasebenziyo. I-arhente yokuqinisa esebenzayo ibhekisa kwikhonkco layo le-molecular equlathe amaqela asebenzayo anokusabela kwi-matrix resin, enokwenza isakhiwo senethiwekhi, yongeze inxalenye yekhonkco eguquguqukayo, kwaye ngaloo ndlela iphucule ukumelana nempembelelo kwezinto ezidityanisiweyo. I-arhente yokuqinisa engasebenziyo luhlobo lwe-arhente yokuqinisa enyibilikayo kwi-matrix resin kodwa ayithathi nxaxheba kwi-chemical reaction.
iphakheji kunye nothutho
B. Le mveliso ingasetyenziswa,,25KG，BAERRLS。
C. Gcina ivalwe kwindawo epholileyo, eyomileyo nengena umoya ngaphakathi. Izikhongozeli mazivalwe kakuhle emva kokusetyenziswa ngakunye ngaphambi kokusetyenziswa.
D. Le mveliso kufuneka ivalwe kakuhle ngexesha lokuthuthwa ukuze kuthintelwe ukufuma, i-alkali enamandla kunye ne-asidi, imvula kunye nezinye izinto ezingcolileyo ukuba zingaxubeki.
