imikhiqizo

izici zamakhemikhali

I-toughening agent ibhekisela entweni engakhuphula ukuguquguquka kwefilimu enamathelayo.Okunye okunamathelayo kwe-resin ye-thermosetting, njenge-epoxy resin, i-phenolic resin kanye ne-unsaturated polyester resin adhesives ngemva kokuphulukiswa, ukuphakama okuphansi, ubuthakathaka obukhulu, lapho indawo yokubopha ngaphansi kwamandla angaphandle kulula ukuqhekeka, nokwanda okusheshayo, okuholela ekuqhekekeni, ukumelana nokukhathala, ingasetshenziswa njengesibopho sesakhiwo.Ngakho-ke, kuyadingeka ukunciphisa i-brittleness, ukwandisa ukuqina futhi uthuthukise amandla okuzala.Izinto ezinganciphisa ukuqina futhi zikhulise ukuqina ngaphandle kokuthinta ezinye izici eziyinhloko ze-adhesive i-ejenti eqinisayo.Ingahlukaniswa nge-ejenti eqinisa irabha kanye ne-ejenti eqinisayo ye-thermoplastic elastomer.

Isingeniso somkhiqizo kanye nezici

(1) I-agent ye-Rubber toughening yalolu hlobo lwezinhlobo ze-ejenti eqinisayo ikakhulukazi ihlanganisa irabha ye-polysulfide ewuketshezi, irabha ye-acrylic ewuketshezi, irabha ye-polybutadiene ewuketshezi, irabha ye-nitrile, irabha ye-ethylene propylene kanye nerabha ye-styrene butadiene, njll.
(2) I-thermoplastic elastomer I-Thermoplastic elastomer iwuhlobo lwento yokwenziwa ekhombisa ukunwebeka kwerabha kuzinga lokushisa elilingana negumbi futhi ingenziwa ipulasitiki ekushiseni okuphezulu.Ngakho-ke, lolu hlobo lwe-polymer lunezici zenjoloba kanye ne-thermoplastic, lungasetshenziswa njenge-ejenti eqinisayo yezinto ezihlanganisiwe, futhi lungasetshenziswa njengento ye-matrix yezinto ezihlanganisiwe.Lolu hlobo lwezinto ezibonakalayo luhlanganisa ikakhulukazi i-polyurethane, i-styrene, i-polyolefin, i-polyester, i-interregular 1, i-2-polybutadiene kanye ne-polyamides neminye imikhiqizo, okwamanje njenge-ejenti eqinisayo yezinto ezihlanganisiwe ezisetshenziswa kakhulu i-styrene ne-polyolefin.
(3) Amanye ama-ejenti aqinisayo Ezinye izinto eziqinisayo ezifanele izinhlanganisela ama-polyamides anesisindo esiphansi samangqamuzana nama-ejenti aqinisayo angasebenzi, njenge-phthalate esters.I-ejenti eqinisayo engasebenzi ingase futhi ibizwe ngokuthi i-plasticizer, engahlanganyeli ekuphenduleni ukuphulukiswa kwe-resin.

sebenzisa

I-ejenti eqinisayo ifanele ama-adhesives, i-raber, i-coatings neminye imikhiqizo.Kuwuhlobo lwe-ejenti eyisizayo enganciphisa ukubola kwezinto eziyinhlanganisela futhi ithuthukise ukumelana nomthelela wezinto eziyinhlanganisela.Ingahlukaniswa nge-ejenti eqinisayo esebenzayo kanye ne-ejenti eqinisayo engasebenzi.I-ejenti eqinisayo esebenzayo ibhekisela ochungechungeni lwamangqamuzana alo aqukethe amaqembu asebenzayo angasabela ngeresin ye-matrix, engakha isakhiwo senethiwekhi, ingeze ingxenye yeketango eliguquguqukayo, ngaleyo ndlela ithuthukise ukumelana komthelela wento eyinhlanganisela.I-ejenti eqinisayo engasebenzi iwuhlobo lwe-ejenti eqinisayo encibilika nge-matrix resin kodwa engabambi iqhaza ekuphenduleni kwamakhemikhali.

iphakethe kanye nezokuthutha

B. Lo mkhiqizo ungasetshenziswa,, 25KG, BAERRLS.
C. Gcina kuvaliwe endlini epholile, eyomile futhi engenamoya.Iziqukathi kufanele zivalwe ngokuqinile ngemva kokusetshenziswa ngakunye ngaphambi kokusetshenziswa.
D. Lo mkhiqizo kufanele uvalwe kahle ngesikhathi sokuthutha ukuvimbela umswakama, i-alkali enamandla ne-asidi, imvula nokunye ukungcola ekuxubeni.
