Toughening agent e fa'atatau i se mea e mafai ona fa'atuputeleina ai le fetuutuunai o le ata fa'apipi'i.O nisi thermosetting resin adhesives, e pei o le epoxy resin, phenolic resin ma unsaturated polyester resin adhesives ina ua uma ona faamaloloina, elongation maualalo, fragility sili atu, pe a faigofie ona ta'e le nofoaga sootaga i lalo o le malosi i fafo, ma le faalauteleina vave, e mafua ai le ta'e, tete'e vaivai, mafai. e le fa'aaogaina e fai ma fa'amauga fa'avae.O le mea lea, e tatau ona faʻaitiitia le brittleness, faʻateleina le faigata ma faʻaleleia le malosi o le tauaveina.O mea e mafai ona faʻaitiitia ai le pala ma faʻateleina le malosi e aunoa ma le afaina ai o isi mea taua o le faʻapipiʻi o le mea faʻamalosi.E mafai ona vaevaeina i le pa'u toughening agent ma thermoplastic elastomer toughening agent

Fa'atomuaga oloa ma foliga

(1) Pa'a toughening agent o lenei ituaiga o toughening agent ituaiga e aofia ai le pa'u polysulfide vai, pa'u pa'u vai, pa'u polybutadiene vai, pa'u nitrile, pa'u ethylene propylene ma pa'u styrene butadiene, ma isi.
(2) elastomer thermoplastic Thermoplastic elastomer o se ituaiga o mea gaosia e faʻaalia ai le elasticity paʻu i le vevela o le potu ma e mafai ona faʻapipiʻiina i le vevela maualuga.O le mea lea, o lenei ituaiga polymer o loʻo i ai uiga o le paʻu ma le thermoplastic, e mafai ona faʻaaogaina e fai ma sui faʻamalosi o mea tuʻufaʻatasia, ma e mafai ona faʻaaogaina e avea ma mea matrix o mea faʻapipiʻi.O lenei ituaiga o mea e masani ona aofia ai le polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene ma polyamides ma isi oloa, i le taimi nei o le sui toughening o mea tuʻufaʻatasia faʻaaogaina sili atu styrene ma polyolefin.
(3) O isi vaila'au fa'ama'a'a O isi vaila'au fa'ama'a'a e talafeagai mo fa'aputuga o polyamides e maualalo le mamafa mole mole ma vaila'au fa'amalosi e le mafai ona gaoioi, e pei ole phthalate esters.E mafai fo'i ona ta'ua se mea fa'amalosi malosi e le toaga o se palasitika, lea e le auai i le fa'amalologa o le resini.

fa'aoga

O le mea faʻamalosi e fetaui lelei mo faʻapipiʻi, paʻu, faʻapipiʻi ma isi oloa.O se ituaiga o fesoasoani fesoasoani lea e mafai ona faʻaititia le brittleness o mea tuʻufaʻatasia ma faʻaleleia le aʻafiaga o mea faʻapipiʻi.E mafai ona vaevaeina i le toughening agent ma le toughening agent.Active toughening agent e faasino i lana filifili mole o loʻo i ai vaega malosi e mafai ona tali atu i le resin matrix, lea e mafai ona fausia ai se fausaga fesoʻotaʻiga, faʻaopoopo se vaega o filifili fetuutuunai, ma faʻaleleia atili ai le aʻafiaga o le mea faʻapipiʻi.O le sui fa'amalosi fa'aletonu o se ituaiga so'o fa'amalosi lea e solu i le matrix resin ae le auai i fa'a'aga fa'ama'i.

afifi ma felauaiga

B. O lenei oloa e mafai ona faʻaaogaina,, 25KG, BAERRLS.
C. Teu fa'amaufa'ailoga i se nofoaga mālūlū, mago ma fa'alili i totonu.O koneteina e tatau ona fa'amaufa'ailoga lelei pe a uma fa'aoga ta'itasi a'o le'i fa'aogaina.
D. O lenei oloa e tatau ona faʻamaufaʻailogaina lelei i le taimi o felauaiga e puipuia ai le susu, malosi alkali ma acid, timu ma isi mea leaga mai le faʻafefiloi.
