Epoxy nebwe: chinokosha kushandisa sectors zvose

Epoxy Resin - fuma ane mukuru kuramba acids, zvigadziko uye halogens. Chinhu chakaita zvokugadzirwa oligomer. Inogona kushandiswa micheto yekapepa katsva aka chero zvinhu. In nemvura hurumende iri pachena epoxy nebwe, iro rine yeyero-Orange ruvara, uye pashure kuomesa zvinova mashava uye kushanda njodzi utano. Zvisinei, kushandiswa kwayo apo pangava zvinogona kuonana zvokufembedzwa, Sol-leachable hacho hazviiti. In nemvura mamiriro zviri chepfu chaizvo, saka kushandiswa kwayo zvinoda kuomerera mitemo.

Chokwadi, nokuti Bonding ndiro kana zvimwe zvinhu kuti apinde kuonana nezvokudya kana mvura yokunwa, hazvigoni kushandiswa chinangwa ichi pane zvimwe zvinhu. Zvisinei, nokuda ehupfumi dzavo epoxy nebwe chinhu chinokosha zvikuru pane yakafara chaizvo zvakawanda maindasitiri. Paine maviri chikuru mashoko: sechinhu namira uye impregnation. Uchibatsirwa rayo kuchengetedza pamusoro ngura nekongiri, simbi, gadzira anoumba, guruu siyana, kunyange zvinokosha kwazvo chikamu mune zvinenge mapazi ose engineering. Epoxy nebwe Washington City Offices vari kutanga zvokuvakisa kugadzirwa girazi faibha, iro zvinowanzoshandiswa kuvaka, boat- uye mhepo indasitiri. Uyewo, kutanga inoshandiswa zadza zvemagetsi uye kunyange magadzirirwo.

Epoxy nebwe rinoshandiswa tandem aine hardener. Apo kupisa kurapwa nezvisingabvumwi mumhuri ezvinhu, vari kushandiswa panzvimbo mumawekishopu duku chando fuma. Uye nokuti zvinhu zvinokosha, zvakagadzirirwa kushanda panguva yakakwirira kunofambira mberi uye guru mitoro mu kungatikanganisa runyararo - hot kurapa nevamiririri. Muchiitiko chino, mumwe denser afoot fastening polymer mamorekuru. Uyezve, pane chimwe epoxy nebwe hardeners, zvakagadzirirwa uchikumbira ezvinhu mukuru mwando, munyu mvura.

Kushanda hwake, zvinofanira kunzwisiswa kuti mukomboni wayo hardener ane exothermic maitiro, uye mukuru uremu polymer kunonyanya kupisa kunotangira. Panyaya iyi zvinokosha kusarudza zvakarurama nhamba nevasori, uye kuti Nenyaya Iyi pamwe nechinangwa kushandiswa, somugumisiro, vanofanira kuwana yunifomu (hapana matema) hwakasimba. Uyezve, zvakaitwa nebwe hardener riri kusingarapiki, uye zvadaro thermoset kusiyana thermoplastic havagoni uchanyauka kana kuiparadza kuti rework mugumisiro. Rakajairika oornag zvokuvakisa okurapa epoxy zvinhu zvava kunzi Pepa, DETA, TETA, TEPA uye №1 (hexamethylene diamine zvazvichanyungudutswa ethyl doro). Nokuti kuti kwakajairika maviri-chikamu remubatanidzwa - a nani kusimba chinhu, ayo elasticity ichiwedzerwa nokuwedzera mumwe zvinoriumba. chaikosha uyu anonzi "kwechirwere modifier", zvingaita kuva zvakasiyana makemikari anoumba uye, zvichienderana ichi, vane mamwe maitiro. mishonga vechokwadi vakaona zvinhu kuti anokwanisa kuita zvose somunhu hardener, uye mwoyo modifier.
