chinosimbisa
hunhu hwemakemikari
Mushonga unosimbisa zvinoreva chinhu chinogona kuwedzera kuchinjika kwefirimu rinonamira. Mamwe maglue anonamira eresin anogadzirisa thermosetting, akadai se epoxy resin, phenolic resin uye unsaturated polyester resin adhesives mushure mekuoma, kurebesa kwakaderera, kusimba kukuru, kana nzvimbo inonamira iri nyore kutsemuka, uye kuwedzera nekukurumidza, zvichikonzera kutsemuka, kuramba kuneta, hazvigone kushandiswa sekubatana kwechimiro. Saka, zvakakosha kuderedza kutsemuka, kuwedzera kusimba uye kuvandudza simba rekutakura. Chinhu chinogona kuderedza kutsemuka uye kuwedzera kusimba pasina kukanganisa zvimwe zvinhu zvikuru zveglue ndiyo mushonga unosimbisa. Inogona kukamurwa kuita musanganiswa werabha unosimbisa uye musanganiswa wethermoplastic elastomer unosimbisa.
Sumo yechigadzirwa uye maficha azvo
(1) Rudzi urwu rwemhando dzerubber toughening agents dzinosanganisira rabha re liquid polysulfide, rabha re liquid acrylic, rabha re liquid polybutadiene, rabha re nitrile, rabha re ethylene propylene uye rabha re styrene butadiene, nezvimwewo.
(2) thermoplastic elastomer Thermoplastic elastomer rudzi rwezvinhu zvakagadzirwa zvinoratidza kusimba kwerabha patembiricha yemumba uye zvinogona kugadzirwa nepurasitiki patembiricha yepamusoro. Saka, rudzi urwu rwepolymer rune hunhu hwerabha nethermoplastic, runogona kushandiswa sechinhu chinosimbisa zvinhu zvakasanganiswa, uye runogona kushandiswa sechinhu chinobatsira pakusimbisa zvinhu zvakasanganiswa. Rudzi urwu rwezvinhu runonyanya kusanganisira polyurethane, styrene, polyolefin, polyester, interregular 1, 2-polybutadiene uye polyamides nezvimwe zvigadzirwa, pari zvino sechinhu chinosimbisa zvinhu zvakasanganiswa chinoshandiswa zvakanyanya se styrene nepolyolefin.
(3) Zvimwe zvinhu zvinosimbisa. Zvimwe zvinhu zvinosimbisa zvakakodzera zvinhu zvinosanganisa zvinhu zvakaita semapolyamides ane huremu hwakaderera uye zvinhu zvinosimbisa zvine huremu hwakaderera, zvakaita semaesters ephthalate. Chinhu chinosimbisa chinogonawo kunzi plasticizer, chisingabatanidzwi mukuita kwe resin inoporesa.
shandisa
Mushonga wekusimbisa wakakodzera maglues, rabha, machira nezvimwe zvigadzirwa. Imhando yemushonga wekubatsira unogona kuderedza kuputsika kwezvinhu zvakasanganiswa uye kuvandudza kuramba kusimba kwezvinhu zvakasanganiswa. Unogona kukamurwa kuita mushonga wekusimbisa unoshanda uye mushonga wekusimbisa unoshanda. Mushonga wekusimbisa unoshanda zvinoreva cheni yayo yemamorekuru ine mapoka anoshanda anogona kuita ne matrix resin, iyo inogona kuumba chimiro che network, kuwedzera chikamu checheni inochinjika, uye nokudaro inovandudza kuramba kusimba kwezvinhu zvakasanganiswa. Mushonga wekusimbisa unoshanda imhando yemushonga wekusimbisa unoshanda unonyungudika ne matrix resin asi haubatanidzwi mumakemikari reaction.
pasuru uye kutakurwa
B. Chigadzirwa ichi chinogona kushandiswa,,25KG，BAERRLS。
C. Chengeta yakavharwa munzvimbo inotonhorera, yakaoma uye ine mhepo mukati. Midziyo inofanira kuvharwa zvakasimba mushure mekushandisa kwega kwega usati washandisa.
D. Chigadzirwa ichi chinofanira kuvharwa zvakanaka panguva yekufambisa kudzivirira hunyoro, alkali yakasimba uye acid, mvura nezvimwe tsvina kuti zvisasanganiswe.
