Ngophuhliso lwetekhnoloji entsha, ukuveliswa kwenayiloni yesi-6 kuye kwangena kumanqanaba obuchwepheshe obutsha obuphezulu.Ngokutsho kokusetyenziswa okuhlukeneyo, inkqubo ye-polymerization ye-nylon 6 inokwahlulwa ibe yilezi zilandelayo.
1. Indlela yepolymerization enamanqanaba amabini
Le ndlela iqulunqwe ngeendlela ezimbini ze-polymerization, ezizezi ze-polymerization zangaphambili kunye neendlela ze-post-polymerization, ezidla ngokusetyenziswa ekuveliseni intambo ye-industrial cord kunye ne-viscosity ephezulu.Iindlela ezimbini ze-polymerization zahlulwe kwi-pre-polymerization pressurization kunye ne-post-polymerization decompression.Kwinkqubo yokuvelisa, uxinzelelo okanye unyango lwe-decompression lwenziwa ngokuthelekisa ixesha le-polymerization, umntu ngamnye kwimveliso kunye ne-poly-poly volume.Ngokuqhelekileyo, indlela yokunciphisa i-post-polymerization ingcono, kodwa idinga utyalo-mali oluninzi, kunye neendleko eziphezulu, ezilandelwa nguxinzelelo oluphezulu kunye noxinzelelo oluqhelekileyo ngokweendleko.Nangona kunjalo, iindleko zokusebenza zale ndlela ziphantsi.Kwi-pre-polymerization yoxinzelelo kunye neendlela zokuvelisa i-post-polymerization decompression, ngexesha loxinzelelo, izithako zemveliso zixutywa kwaye emva koko zonke zifakwe kwi-reactor, kwaye emva koko ukuphendulwa kweringi yokuvula amanzi kunye ne-partial polymerization reaction yenziwa. kwiqondo lobushushu elithile.Inkqubo yi-endothermic reaction.Ubushushu bubekwe kwindawo ephezulu yetyhubhu yepolymer.Ngethuba lenkqubo yoxinzelelo, i-polymer ihlala kwi-polymer tube ixesha elithile kwaye ingena kwi-polymerizer, apho i-viscosity ye-polymer eveliswayo iya kufikelela malunga ne-1.7.
2. Indlela yepolymerization eqhubekayo kuxinzelelo oluqhelekileyo
Le ndlela isetyenziselwa ukuveliswa kweribhoni yasekhaya ye-nylon 6. Iimpawu: I-polymerization enkulu eqhubekayo yamkelwa ngobushushu obufikelela kwi-260 ℃ kunye nexesha le-polymerization kwiiyure ezingama-20.I-oligomer eseleyo kwicandelo ifunyenwe xa amanzi atshisayo ephikisana nomsinga.Ulawulo lwenkqubo yokuhanjiswa kwe-DCS kunye nokomisa umoya kwegesi ye-ammonia nazo zamkelwa.Inkqubo yokubuyisela i-monomer ithatha itekhnoloji ye-evaporation yesiphumo esithathu esiqhubekayo kunye nogxininiso kunye ne-discontinuous distillation kunye noxinzelelo lwamanzi akhutshiweyo.I-Advantages yendlela: Ukusebenza okuqhubekayo okuqhubekayo kwemveliso, imveliso ephezulu, umgangatho ophezulu wemveliso, indawo encinci ehlala kwinkqubo yokuvelisa.Indlela iteknoloji eqhelekileyo kwimveliso yeribhoni yasekhaya yangoku.
3. Indlela ye-autoclave ye-polymerization yohlobo lwethutyana
Isetyenziswa ngokubanzi kwimveliso yeeplastiki ezincinci zobunjineli.Umlinganiselo wemveliso yi-10 ukuya kwi-12t / d;Imveliso ye-autoclave enye yi-2t / ibhetshi.Ngokuqhelekileyo, uxinzelelo kwinkqubo yokuvelisa ngu-0.7 ukuya kwi-0.8mpa, kwaye i-viscosity inokufikelela kwi-4.0, kunye ne-3.8 ngexesha eliqhelekileyo.Kungenxa yokuba ukuba i-viscosity iphezulu kakhulu, imveliso iya kuba iphantsi.Ingasetyenziselwa ukuvelisa i-pa 6 okanye i-pa 66. Indlela inenkqubo yokuvelisa elula, ekulula ukutshintsha iintlobo kunye nokuguquguquka kwimveliso.
