toughener
makemikari maitiro
Toughening agent inoreva chinhu chinogona kuwedzera kuchinjika kwefirimu rinonamira.Mamwe anonamatira epoxy resin, epoxy resin, phenolic resin uye unsaturated polyester resin adhesives mushure mekurapa, kureba kwakadzika, fragility yakakura, apo nzvimbo yekubatanidza iri pasi pesimba rekunze iri nyore kutsemuka, uye kuwedzera nekukurumidza, zvichikonzera kuputika, kuneta kuramba, kunogona. isingashandiswe sechisungo chemuumbirwo.Nokudaro, zvakakosha kuderedza brittleness, kuwedzera kuoma uye kuvandudza simba rekubereka.Izvo zvinhu zvinogona kuderedza brittleness uye kuwedzera kuomarara pasina kukanganisa mamwe makuru maficha eanonamatira ndiyo inoomesa mumiriri.Inogona kukamurwa kuita rabha toughening agent uye thermoplastic elastomer toughening agent.
Kusuma chigadzirwa uye maitiro
(1) Rubber toughening agent iyi mhando yemhando dzinoomesa mumiririri kunyanya dzinosanganisira liquid polysulfide rabha, liquid acrylic rabha, liquid polybutadiene rabha, nitrile rabha, ethylene propylene rabha uye styrene butadiene rabha, nezvimwewo.
(2) thermoplastic elastomer Thermoplastic elastomer imhando yezvigadzirwa zvekugadzira zvinotaridza elasticity yerabha patembiricha yekamuri uye inogona kuiswa mupurasitiki pakupisa kwakanyanya.Naizvozvo, rudzi urwu rwepolymer rine hunhu hwezvose rabha uye thermoplastic, inogona kushandiswa seyakaomesesa mumiriri wezvakaumbwa zvinhu, uye inogona kushandiswa sematrix zvinhu zvemusanganiswa zvinhu.Rudzi urwu rwezvinhu zvinonyanya kusanganisira polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene uye polyamides nezvimwe zvigadzirwa, parizvino seyakaomesesa mumiriri wezvinhu zvinosanganiswa zvinoshandiswa zvakanyanya styrene uye polyolefin.
3Iyo isingashande toughening agent inogonawo kunzi plasticizer, iyo isingabatanidzi mukurapa maitiro eresin.
use
Iyo toughening agent inokodzera zvinonamira, rabha, machira uye zvimwe zvigadzirwa.Iyo imhando yeanobatsira mumiriri iyo inogona kuderedza brittleness yezvinhu zvinoumbwa uye kugadzirisa kupikisa kwemaitiro ezvakasanganiswa zvinhu.Inogona kukamurwa kuita inoshanda toughening agent uye isingashande toughening agent.Active toughening agent inoreva kune yayo molecular cheni ine mapoka anoshanda anogona kuita ne matrix resin, iyo inogona kugadzira network chimiro, kuwedzera chikamu cheinochinjika cheni, uye nekudaro inovandudza kupikisa kweiyo inoumbwa zvinhu.Inactive toughening agent imhando yekuomesa mumiririri inonyungudika nematrix resin asi isingabatanidzike mukuita kwemakemikari.
pasuru uye chokufambisa
B. Ichi chigadzirwa chinogona kushandiswa,, 25KG, BAERRLS.
C. Chengetedza chakavharwa munzvimbo inotonhorera, yakaoma uye inofefetera mukati memba.Midziyo inofanira kuvharwa zvakasimba mushure mekushandiswa kwega kwega isati yashandiswa.
D. Ichi chigadzirwa chinofanira kuiswa chisimbiso zvakanaka panguva yekufambisa kudzivirira unyoro, alkali yakasimba uye asidi, mvura uye zvimwe tsvina kubva pakusanganiswa.
