Kwagura urunigi ni ubwoko bwibintu bishobora kwagura urunigi kandi byongera
uburemere bwa molekulari mugukora hamwe nitsinda ryimikorere kumurongo wa polymer.
Mubisanzwe bikoreshwa mugutezimbere imiterere yubukanishi nuburyo bwo gutunganya
polyurethane, polyester, nylon nibindi bicuruzwa.
Epoxy yagura urunigi niyagura urunigi rurimo glycidyl methacrylate (GMA).
Ubusanzwe ikoreshwa rya epoxy urunigi rurimo styrene-glycidyl methacrylate, ifite
ituze ryiza ryumuriro kandi irashobora gukorerwa impeta ifungura imiti hamwe na PA6, aho
kuvanga umubiri neza.Irashobora kandi gukoreshwa mumyanda PET itunganya nibindi bintu.Uwiteka
imikorere ya epoxy urunigi rwagutse muri nylon yahinduwe niyi ikurikira:
1. Ingaruka kuburemere bwa molekuline hamwe nubwiza bwimbere
Epoxy urunigi rwagutse rushobora kwitwara hamwe nitsinda rya nyuma rya amino hamwe na carboxyl ya nyuma ya
PA6, hanyuma utezimbere uburemere bwa molekuline ya PA6.Ariko, gelation irashobora kubaho mugihe
kwagura urunigi reaction, birakenewe rero kugenzura ibihe bikwiye, cyane cyane
ubushyuhe n'umuvuduko wa screw, kugirango wirinde guhuza kwambuka.
Ubwiza bwimbere bwa PA6 bwiyongereye vuba hamwe no kwiyongera kwurunigi
umuguzi.Iyo ibikubiye mu kwagura urunigi byiyongereye kugeza ku gice runaka ,.
imbere imbere ya PA6 yagabanutseho gato.Ni ukubera ko itsinda ryanyuma rya PA6 rishobora
reba vuba hamwe na epoxy groupe mu kwagura urunigi kubera polarite na hydrogen
inkwano.Iyo ingano yo kwagura urunigi iringaniye, igipimo cyurunigi rurerure
molekile muri sisitemu iriyongera kandi ubwiza bwiyongera bikwiranye;
Ariko, nkareaction irakomeza, iherezo ryitsinda rya PA6 riragabanuka, no kugongana
ibishoboka kuriiherezo ryurunigi rwa molekile iragabanuka cyane kubera ingaruka za
gukwirakwiza ubushyuhen'uburebure bw'urunigi rwa molekile, hiyongereyeho, kwagura urunigi cyane
bishobora kuganisha kuri ageli nkeya muri sisitemu, biganisha ku kugabanuka kwaguka
gukora nezana PA6 ubwiza bwimbere.
2. Ingaruka kumiterere yubukanishi
Ubwinshi bwa molekile ya PA6 yariyongereye nyuma yo kwagura urunigi hamwe na epoxy
kwaguka, Gukomera kwibikoresho birashobora kunozwa neza mugabanuka
kristu n'ubunini bw'ingano. Mubyongeyeho, hamwe no kwiyongera k'uburebure bw'urunigi rwa molekile,
guhuzagurika hagati y'iminyururu biriyongera, kandi urunigi rwa molekile biragoye kunyerera.Muri
ubu buryo, imbaraga zingaruka zirashobora gukoreshwa muguhindura imiterere ya molekile
urunigi iyo byatewe nisi yo hanze.Ariko iyo igice kinini cyurunigi rwagutse
irenze igipimo runaka, ibintu byose byubukanishi biragabanuka./n
3. Ingaruka kumiterere ya rheologiya
Umuvuduko wo gutemba (MFR) wagabanutse cyane hamwe no kwiyongera kwa epoxy urunigi,
byerekana ko kwagura urunigi rwa epoxy na PA6 byagize ingaruka nziza yo kwagura urunigi.
Hamwe no kwiyongera kwinshi kwagura urunigi, torque ya equilibrium yiyongereye mbere
hanyuma bikagabanuka, kubera uburemere bwa molekuline ya PA6 nyuma yo kwagura urunigi
yariyongereye, ibizunguruka mu ruhererekane rwa molekile byariyongereye, kandi ibishishwa bya elegitoronike nabyo
yiyongereye, bityo torque ya equilibrium yariyongereye.
Hamwe nigihe cyigihe, pellet ya PA6 yoroshye, yegeranye kandi ishonga buhoro buhoro ,.
kurwanya rotor byagabanutse, kandi torque nayo yagabanutse.
