Kupisa uye chiedza chezuva zvichakanganisa nguva yekuchengetedza ye unsaturated polyester resin.Muchokwadi, ingave isina unsaturated polyester resin kana mamwe marezeni, tembiricha yekuchengetera ingangoita 25 degrees Celsius munzvimbo yazvino.Pahwaro uhwu, kuderera kwekushisa, iyo yakareba nguva yechokwadi yeunsaturated polyester resin;iyo yakakwirira tembiricha, ipfupi nguva yechokwadi.
Iyo resin inoda kuiswa chisimbiso uye kuchengetwa mumudziyo wekutanga kudzivirira kurasikirwa kwemonomer volatilization uye kudonha kwetsvina yekunze.Uye chivharo chevhavha yekuchengetera resin haifanirwe kugadzirwa nemhangura kana mhangura alloy, zviri nani polyethylene, polyvinyl chloride uye mamwe simbi lids.
Kazhinji, mumamiriro ekupisa kwepamusoro, dzivirira zuva rakananga kudhiramu yekurongedza, asi nguva yekuchengetera icharamba ichikanganiswa, nekuti mukupisa kwemamiriro ekunze, nguva yegel yeresin ichapfupikiswa zvakanyanya, kana iri resin yemhando yakashata. , kunyangwe Ichasimbisa zvakananga mudhiramu rekurongedza.Nokudaro, munguva yekushisa kwepamusoro, kana mamiriro ezvinhu achibvumira, zvakanakisisa kuichengeta muimba yekuchengetera air-conditioned ine tembiricha isingaperi ye25 degrees Celsius.Kana mugadziri asina kugadzirira imba yekuchengetera mhepo, inofanirwa kutarisisa kupfupisa nguva yekuchengetedza resin.
Zvakakosha kucherechedza kuti resin yakasanganiswa nestyrene inofanira kubatwa semahydrocarboni anopisa kudzivirira moto.Panofanira kuva nekutonga kwakasimba kwematura uye zvirimwa zvinochengeta rudzi urwu rweresin, uye kudzivirira moto uye basa rekupisa rinofanira kuitwa nguva dzose.
Nyaya dzekuchengetedza dzinofanirwa kutariswa panguva yekugadziriswa kweunsaturated polyester resin mumusangano
1. Resin, kuporesa mumiririri, uye accelerator zvinhu zvose zvinopisa, saka kudzivirira moto kunofanira kubhadharwa, uye inofanira kuchengetwa zvakasiyana, kana zvisina kudaro zviri nyore kwazvo kukonzera kuputika.
2. Panofanira kunge pasina kuputa uye pasina moto wakavhurika mumusangano wekugadzira.
3. Musangano wekugadzira unofanirwa kuchengetedza mhepo yakakwana.Kune mafomu maviri eweworkshop ventilation, imwe ndeyekuchengetedza mukati memhepo kutenderera, kuitira kuti ubvise inoputika styrene chero nguva.Nekuda kwekuti styrene vapor yakaoma kupfuura mweya, iyo styrene concentration padyo nepasi zvakare yakakwira.Nokudaro, mhepo yekupedza mumusangano inonyatsogadzirirwa pedyo nevhu.Imwe yacho ndeyekushandisa maturusi nemidziyo yekupedza nzvimbo yekushanda.Semuyenzaniso, gadzira yakaparadzana exhaust feni kuti ibvise yakakwira-concentration styrene mhute kubva munzvimbo yekushanda, kana kupedza gasi reflue kuburikidza nepombi huru yekusveta yakaiswa muwekishopu.
4. Kuti utarise zviitiko zvisingatarisirwi, musangano wekugadzira unofanirwa kunge uine mabudiro maviri.
5. Iyo resin uye zvakasiyana-siyana zvinokurumidza zvakachengetwa mumusangano wekugadzira hazvifaniri kunge zvakanyanyisa, zvakanakisisa kuchengetedza zvishoma.
6. Mishonga isina kushandiswa asi yakawedzerwa ne accelerators inofanira kuendeswa kune imwe nzvimbo yakachengeteka uye yakachengetwa zvakasiyana kuti idzivirire huwandu hwakawanda hwekupisa kubva pakuunganidza uye kukonzera kuputika uye moto.
7. Kana iyo unsaturated polyester resin yadonha uye ichikonzera moto, magasi ane muchetura anoburitswa mukuita uye kuisa hutano hwevanhu mungozi.Nokudaro, matanho ekukurumidzira anofanirwa kutorwa kugadzirisa.
