Zvese tembiricha uye chiedza chezuva zvinogona kukanganisa nguva yekuchengetedza yeunsaturated polyester resins.Muchokwadi, ingave isina unsaturated polyester resin kana yakajairwa resin, tembiricha yekuchengetera ndiyo yakanyanya kunaka panguva ino tembiricha yedunhu ye25 degrees Celsius.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 chifukidziro chekuputira chirongo chekuchengetedza resin haigoni kugadzirwa nemhangura kana mhangura yemhangura, uye zvakanakisisa kushandisa polyethylene, polyvinyl chloride uye mamwe mavharo esimbi.
Kazhinji kutaura, kana iri tembiricha yakakwira, zvakakwana kudzivirira zuva rakananga kudhiramu yekurongedza.Zvisinei, hupenyu hwesherufu hucharamba huchikanganiswa, nokuti mumamiriro ekunze ekupisa, nguva yegel ye resin ichapfupiswa zvikuru, uye kana resin iri yehutano husina kunaka, inotozoporeswa zvakananga mumugodhi wekutakura.
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 dzakasanganiswa nestyrene dzinofanirwa kugadziriswa semahydrocarboni anopfuta kudzivirira moto.Matura uye maworkshop anochengeta marekeni aya anofanirwa kuve nekutonga kwakasimba, uye kuita basa rakanaka rekudzivirira moto nekudzivirira moto chero nguva.
Nyaya dzekuchengetedza dzinofanirwa kutariswa panguva yekugadziriswa kweyakazara polyester resin mumusangano
1. Resin, kuporesa mumiririri uye accelerator zvose zvinhu zvinopisa, uye kuchenjerera kunofanira kubhadharwa kudzivirira moto.Mamwe ma accelerator uye resins anofanirwa kuchengetwa zvakasiyana, zvikasadaro zviri nyore kukonzera kuputika.
2. Panofanira kunge pasina kuputa uye pasina moto wakavhurika mumusangano wekugadzira.
3. Musangano wekugadzira unofanirwa kuchengetedza mhepo yakakwana.Pane nzira mbiri dzekufefetedza muwekishopu.Imwe ndeyekuchengetedza mukati memhepo kutenderera kwemukati kuitira kuti volatiles ye styrene inogona kubviswa chero nguva.Nekuda kwekuti styrene vapor yakaoma kupfuura mhepo, iyo styrene iri padyo nepasi zvakare yakakwira.Naizvozvo, zviri nani kuseta mhepo yekubuda mumusangano padyo nepasi.Imwe yacho ndeyekupedza nzvimbo yekushanda nerubatsiro rwezvishandiso nemidziyo.Semuyenzaniso, imwe feni yekupedza simba inogadzikwa kuti ibudise iyo yakakwira-concentration styrene mhute inoburitswa munzvimbo yekuvhiya, kana gasi reflue rinopera kuburikidza nepombi yekusveta yakawanda yakaiswa muwekishopu.
4. Kuti utarise zviitiko zvisingatarisirwi, musangano wekugadzira unofanirwa kunge uine mabudiro maviri.
5. Resin uye zvakasiyana-siyana zvinokurumidza zvakachengetwa mumusangano wekugadzira hazvifaniri kunge zvakanyanyisa, uye zvakanakisisa kuchengetedza zvishoma.
6. Mishonga isina kushandiswa asi yakawedzerwa ne accelerators inofanira kuendeswa kunzvimbo yakachengeteka yekuchengetedzwa kwakapararira, kuitira kudzivirira kuwanda kukuru kwekupisa kuunganidza mukuunganidza uye kukonzera kuputika nemoto.
7. Kana iyo unsaturated polyester resin ichidonha, inokonzeresa moto, uye gasi rine muchetura richaburitswa panguva iyi, izvo zvinozoisa mungozi hutano hwevanhu.Nokudaro, matanho ekukurumidzira anofanirwa kutorwa kugadzirisa.
