Waa maxay hababka Polymerization ee Naylon 6?

Horumarinta tignoolajiyada cusub, wax soo saarka naylon 6 ayaa soo galay darajooyinka tignoolajiyada cusub ee cusub ee waaweyn.Marka loo eego isticmaalka kala duwan, habka polymerization ee naylon 6 waxaa loo qaybin karaa kuwan soo socda.

1. Habka polymerization-ka ee laba-heer

Habkani wuxuu ka kooban yahay laba hab oo polymerization, kuwaas oo pre-polymerization iyo hababka post-polymerization, kaas oo inta badan loo isticmaalo in wax soo saarka ee dharka xadhig warshadaha leh viscosity sare.Labada hab ee polymerization waxay u qaybsan yihiin cadaadis-ka-hortagga-polymerization-ka iyo dib-u-dhigista-polymerization-ka.Habka wax-soo-saarka, cadaadiska cadaadiska ama daweynta depression waxaa lagu fuliyaa iyadoo loo eegayo isbarbardhigga wakhtiga polymerization, shakhsi ahaaneed ee alaabta iyo mugga poly-hooseeya.Guud ahaan, habka dib-u-dejinta polymerization-ka ayaa ka fiican, laakiin waxay u baahan tahay maalgashi badan, iyo kharash badan, oo ay ku xigto cadaadis sare iyo cadaadiska caadiga ah ee kharashka.Si kastaba ha ahaatee, kharashka hawlgalka ee habkani waa mid hooseeya.Cadaadiska pre-polymerization iyo hababka wax-soo-saarka ka-hortagga-polymerization-ka, inta lagu jiro marxaladda cadaadiska, maaddooyinka wax-soo-saarka ayaa la isku daraa ka dibna dhammaantood waxaa lagu dhejiyaa reactor, ka dibna falcelinta giraanta-furitaanka biyaha iyo fal-celinta polymerization qayb ayaa la sameeyaa. heerkul gaar ah.Nidaamku waa falcelin endothermic ah.Kuleylku wuxuu ku yaalaa qaybta sare ee tuubada polymer.Inta lagu jiro habka cadaadiska, polymer-ku wuxuu ku sii jirayaa tuubada polymerka in muddo ah ka dibna wuxuu galaa polymerizer, halkaas oo viscosity ee polymer-ka la soo saaro uu gaari doono ilaa 1.7.

2. Habka polymerization joogto ah ee cadaadiska caadiga ah

Habkan waxaa loo isticmaalaa wax soo saarka ee ribbon gudaha ee naylon 6. Features: polymerization weyn oo joogto ah waxaa lagu ansixiyay heerkulka ilaa 260 ℃ iyo waqti polymerization ah 20 saacadood.Oligomer-ka soo haray ee qaybta waxaa la helaa marka biyaha kulul ay ka soo horjeedaan hadda.Habka qaybinta DCS iyo hawo engejinta gaaska ammonia sidoo kale waa la qaatay.Habka soo kabashada monomer wuxuu qaataa teknoolojiyadda uumi-saamaynta joogtada ah ee saddex-saamaynta iyo fiirsashada iyo kala-baxa joojinta iyo xoojinta biyaha la soo saaray.Faa'iidooyinka habka: Wax-qabadka joogtada ah ee wax-soo-saarka, wax-soo-saarka sare, tayada sare ee tayada, aagga yar ee ku-meel-gaadhka ah ee habka wax-soo-saarka.Habka ayaa ah tignoolajiyada caadiga ah ee wax soo saarka gudaha ee hadda jira.

3. Habka polymerization autoclave nooca kala go'a

Waxaa si weyn loogu isticmaalaa soo saarista balaastikada yar-yar ee injineernimada.Miisaanka wax soo saarku waa 10 ilaa 12t/d;Wax soo saarka hal autoclave waa 2t/dufcaddii.Guud ahaan, cadaadiska habka wax soo saarka waa 0.7 ilaa 0.8mpa, iyo viscosity wuxuu gaari karaa 4.0, iyo 3.8 waqti caadi ah.Taasi waa sababta oo ah haddii viscosity-gu aad u sarreeyo, wax soo saarku wuxuu ahaan doonaa mid hooseeya.Waxaa loo isticmaali karaa si loo soo saaro pa 6 ama pa 66. Habka ayaa habka wax soo saarka fudud, taas oo ay fududahay in la beddelo noocyo iyo dabacsanaan wax soo saarka.
