Nekuvandudzwa kwetekinoroji nyowani, kugadzirwa kwenaironi 6 kwapinda muzvinhanho zvemahombe epamusoro-nyowani matekinoroji.Zvinoenderana nekushandiswa kwakasiyana, iyo polymerization process yenylon 6 inogona kukamurwa kuita zvinotevera.
1. Nzira mbiri dzepolymerization
Iyi nzira inoumbwa nenzira mbiri dzepolymerization, dzinoti pre-polymerization uye post-polymerization nzira, iyo inowanzoshandiswa mukugadzirwa kweindasitiri tambo jira rine yakakwira viscosity.Idzi nzira mbiri dzepolymerization dzakakamurwa kuita pre-polymerization pressurization uye post-polymerization decompression.Muchigadzirwa chekugadzira, kudzvanywa kana decompression kurapwa kunoitwa zvinoenderana nekuenzaniswa kwepolymerization nguva, munhu mune chigadzirwa uye yakaderera-poly vhoriyamu.Kazhinji, iyo post-polymerization decompression nzira iri nani, asi inoda mari yakawanda, uye mutengo wepamusoro, uchiteverwa nekumanikidza kwakanyanya uye kudzvanywa kwakajairika maererano nemutengo.Zvisinei, mari yekushanda kweiyi nzira yakaderera.Mune pre-polymerization kudzvanywa uye post-polymerization decompression nzira dzekugadzira, panguva yekudzvanya nhanho, zvinongedzo zvekugadzira zvinosanganiswa uye zvese zvinoiswa mureactor, uye ipapo mvura-inovhura mhete yekuita uye chikamu polymerization reaction inoitwa. pane imwe tembiricha.Iyo nzira ndeye endothermic reaction.Kupisa kunowanikwa pachikamu chepamusoro chepolymer chubhu.Munguva yekumanikidza, iyo polima inogara mupolymer chubhu kwenguva yakati yozopinda mupolymerizer, umo viscosity yepolymer inogadzirwa inosvika 1.7.
2. Kuenderera mberi kwepolymerization nzira pakumanikidzwa kwakajairika
Iyi nzira inoshandiswa kugadzira ribhoni repamba renaironi 6. Zvimiro: Yakakura inoenderera mberi polymerization inotorwa nekudziya kunosvika 260 ℃ uye nguva yepolymerization kwemaawa makumi maviri.Iyo yakasara oligomer muchikamu inowanikwa apo mvura inopisa inopesana nezvino.DCS kugovera sisitimu yekudzora uye ammonia gasi kuomeswa kwemhepo inogamuchirwa zvakare.Iyo nzira yekudzoreredza monomer inotora tekinoroji yekuenderera mberi kwehutatu-effect evaporation uye kuisa pfungwa uye discontinuous distillation uye kusungirirwa kwemvura yakabviswa.Mabhenefiti eiyo nzira: Yakanakisa kuenderera kwekuita kwekugadzira, yakakwira kuburitsa, yakakwirira chigadzirwa mhando, nzvimbo diki inogarwa mukugadzira maitiro.Iyo nzira ndeye yakajairika tekinoroji mukugadzirwa kweribhoni repamba razvino.
3. Inopindirana mhando autoclave polymerization nzira
Inoshandiswa zvakanyanya mukugadzirwa kwediki-batch engineering mapurasitiki.Chiyero chekugadzira ndeye 10 kusvika ku12t / d;Kubuda kweimwe autoclave ndeye 2t/batch.Kazhinji, kumanikidzwa mukugadzirwa kwe 0.7 kusvika 0.8mpa, uye viscosity inogona kusvika 4.0, uye 3.8 panguva yakajairika.Imhaka yekuti kana iyo viscosity yakanyanya kukwira, inobuda ichave yakaderera.Inogona kushandiswa kubudisa pa 6 kana pa 66. Nzira yacho ine nzira yekugadzira iri nyore, iyo iri nyore kuchinja marudzi uye inoshanduka pakugadzirwa.
