KUPAKA UYE KUCHENGETA
• Chigadzirwa chacho chinofanira kuiswa mumudziyo wakachena, wakaoma, wakachengeteka uye wakavharwa, uremu hwemambure 220 Kg.
• Hupenyu hweSherufu: Mwedzi mitanhatu pasi pe25℃, yakachengetwa munzvimbo inotonhorera uye mutsime
nzvimbo ine mhepo.
• Chero chipi chinodikanwa chekurongedza, ndapota taura neboka redu rekutsigira
CHERECHEDZA
• Ruzivo rwese rwuri mukhathalogi ino runobva paGB/T8237-2005 bvunzo dzakajairwa, chete dzekutarisa; pamwe siyana kubva chaiyo bvunzo data.
• Mukugadzirwa kwekushandisa zvigadzirwa zve resin, nokuti kushanda kwezvigadzirwa zvevashandi kunokanganiswa nezvinhu zvakawanda, zvakakosha kuti vashandisi vazviongorore ivo pachavo vasati vasarudza uye kushandisa zvigadzirwa zve resin.
• Mafuta epolyester asina kusimba uye anofanirwa kuchengetwa ari pasi pe25°C mumumvuri unotonhorera, anotakurwa mumotokari yemufiriji kana usiku, asingapine zuva.
• Chero mamiriro asina kukodzera ekuchengetedza uye ekufambisa anokonzeresa kupfupikiswa kwehupenyu hwesherufu.
MASHOKO
• 7937 resin haina wax, accelerator uye thixotropic additives.
• 7937 resin inokodzera kurapa pane tembiricha yekamuri uye yepakati tembiricha. Kurapa tembiricha yepakati kunobatsira pakugadzirisa kugadzirwa uye kuvimbiswa kwekuita kwechigadzirwa. Yakakurudzirwa yepakati tembiricha yekurapa system: tert-butyl peroxide isooctanoate TBPO (zviri mukati ≥97%), 1% resin content; kurapa tembiricha, 80 ± 5 ℃, kurapa kwete asingasviki maawa 2.5. Inokurudzirwa coupling agent: γ-methacryloxypropyl trimethoxysilane KH-570, 2% resin content.
• 7937 resin ine yakafara applicability; inokurudzirwa kusarudza 7982 resin kana o-phenylene-neopentyl glycol 7964L resin nepamusoro pekuita zvinodiwa; inokurudzirwa kusarudza m-phenylene-neopenyl glycol 7510 nokuda kwekudzivirira kwemvura yakakwirira, kupisa kwekushisa uye kusagadzikana kwemamiriro ekunze. Resin; kana iyo midziyo ichigona kuzadzisa zvinodiwa, ndapota sarudza yakaderera-viscosity isophthalic 7520 resin, iyo ine hupfumi uye ine kuita zvirinani.
• Mukugadzirwa kwechigadzirwa, mushure mekupisa uye kuporesa, inofanira kuderedzwa zvishoma nezvishoma kusvika kune imwe nzvimbo yekushisa, kudzivisa kutonhora nokukurumidza, kudzivirira kushanduka kwechigadzirwa kana kuputika, kunyanya munguva yechando. Kuchekwa uye kupukuta kwedombo requartz mukugadzira kunofanirwa kuitwa mushure mekukwana kwekupora.
• Kutora unyoro hwekuzadza kunofanira kudziviswa. Kuwedzeredza hunyoro huchakanganisa kurapwa kwechigadzirwa uye kukonzera kuderera kwekuita.
