Fidiyaha silsilada waa nooc ka mid ah shay balaadhin kara silsiladda molecular oo kordhin karta
Miisaanka molecular adiga oo ka falcelinaya kooxda shaqaynaysa ee silsiladda polymer-ka ee toosan.
Caadi ahaan loo isticmaalo si loo hagaajiyo sifooyinka farsamada iyo sifooyinka
polyurethane, polyester, naylon iyo alaabooyin kale.
Fidiyaha silsiladda Epoxy waa silsilad fidiye ka kooban glycidyl methacrylate (GMA) .
Fidiyeyaasha silsiladda epoxy ee sida caadiga ah loo isticmaalo waxaa ka mid ah styrene-glycidyl methacrylate, kaas oo leh
xasilloonida kulaylka wanaagsan waxayna mari kartaa falcelinta kiimikaad ee furitaanka giraanta ee PA6, halkii ay ka ahaan lahayd
isku dhafka jirka saafiga ah.Waxa kale oo loo isticmaali karaa qashinka dib-u-warshadaynta PET iyo dhinacyo kale.The
Shaqada fidiyeyaasha silsiladda epoxy ee naylon la beddelay waa sida soo socota:
1. Saamaynta miisaanka molecular iyo viscosity gudaha
Fidiyeyaasha silsiladda Epoxy waxay la falcelin karaan kooxda amino-da ee dhamaadka ah iyo kooxda dhamaadka karboxyl ee
PA6, ka dibna wanaaji miisaanka molecular ee PA6.Si kastaba ha ahaatee, gelation waxaa laga yaabaa inay dhacdo inta lagu jiro
falcelinta silsiladda fidinta, markaa waa lagama maarmaan in la xakameeyo xaaladaha ku habboon, gaar ahaan
heerkulka iyo xawaaraha isbiirtada, si looga hortago isku-tallaabta ee soo-baxa falcelinta.
Viscosity-ga gudaha ee PA6 ayaa si degdeg ah u kordhay iyadoo korodhka qaddarka silsiladda
fidiyaha.Marka waxa ku jira silsilad fidiyaha ay korodhay oo gaadhay jajab tiro gaar ah,
viscosity gudaha ee PA6 wax yar ayaa hoos u dhacay.Tani waa sababta oo ah kooxda terminal ee PA6 ayaa awood u leh
si degdeg ah uga falceli kooxda epoxy-ga ee silsiladda fidiyaha ah sababtuna tahay polarity iyo hydrogen
bond.Marka qadarka fidiyaha silsiladuhu dhexdhexaad yahay, saamiga silsiladda dheer
molecules ee nidaamka ayaa kor u kaca, viscosity-kuna wuu kordhaa si waafaqsan;
Si kastaba ha ahaatee, sidafalcelintu way socotaa, waxa kooxda dhamaadka ah ee PA6 hoos u dhacaysa, iyo isku dhaca
ixtimaalka atdhammaadka silsiladda kelli si weyn ayaa loo dhimay iyadoo ay ugu wacan tahay saameynta
fidinta kulaylkaiyo dhererka silsiladda molecular, marka lagu daro, silsilad aad u badan
waxay keeni kartaa aqadar yar oo jel ah oo ku jira nidaamka, taas oo keenta hoos u dhac ku yimaada silsiladda
hufnaaniyo PA6 viscosity gudaha.
2. Saamaynta guryaha farsamada
Tirada molecular-ka qaraabada ah ee PA6 waa la kordhiyey ka dib markii silsilad la kordhiyey oo leh silsilad epoxy
fidiyaha, Adkaynta walxaha si wax ku ool ah ayaa loo wanaajin karaa iyadoo la dhimayo
crystallinity iyo xajmiga hadhuudhka. Intaa waxaa dheer, iyadoo la kordhinayo dhererka silsiladda kelli,
Isku-xidhka u dhexeeya silsiladaha ayaa kordha, silsiladda molecular way adag tahay inay simbiriirixato.Gudaha
habkan, tamarta saameynta waxaa lagu nuugi karaa iyadoo la bedelayo qaabeynta molecular
silsiladda marka ay saamayso dunida dibaddu.Laakiin marka jajabka tirada badan ee silsilad extender
dhaafo qayb go'an, dhammaan sifooyinka farsamada waa la dhimay./n
3. Saamaynta guryaha rheological
Heerka qulqulka dhalaalka (MFR) ayaa si weyn hoos ugu dhacay kororka silsiladda epoxy-ga,
taas oo muujinaysa in fidiyaha silsiladda epoxy-ga iyo PA6 ay lahaayeen falcelin fidineed silsilad wax ku ool ah.
Kordhinta tirada silsiladaha fidiyaha, qulqulka dheellitirka ayaa kordhay markii hore
ka dibna hoos u dhacay, sababtoo ah miisaanka molecular qaraabo ee PA6 ka dib kordhin silsilad
kordhay, isku-xidhka silsiladda molecular ayaa kordhay, iyo viscosity dhalaalay sidoo kale
kor u kacay, sidaas awgeed qulqulka dheellitirka ayaa kordhay.
Iyadoo wakhtigu socdo, pellet-ka PA6 wuu jilicsanaa, waa la isku duubay oo si tartiib tartiib ah u dhalaalay,
iska caabinta rotor-ka ayaa hoos u dhacay, iyo qulqulka ayaa sidoo kale hoos u dhacay.
