Soo bandhigida polyamid pa6
Polyamide, oo loo yaqaan polyamide pa gaaban, ayaa badanaa loo yaqaannaa naylon.Waa nooc ka mid ah balaastiigga heerkulbeegga crystalline ee lagu sameeyay polymerization of amines binary iyo diacid ama lactam.Waxaa jira noocyo badan oo PA ah, marka loo eego tirada atamka kaarboon ee monomer ku lug leh falcelinta polymerization, iyo noocyo kala duwan oo PA oo leh bandhigyo kala duwan ayaa la samayn karaa, sida PA6, PA66, PA612, PA1010, PA11, PA12, PA46 , PA9, PA1212, iwm. PA6 iyo PA66 ayaa inta badan la isticmaalaa, oo xisaabiya 90% wadarta wax soo saarka.
Tilmaamaha guud ee polyamid pa6
Polyamid pa6 waxay leedahay polarity, taas oo aan sun ahayn, aan dhadhamin oo fudud in la midabeeyo; Nooca crystalline (50 ilaa 60%), caano cad oo iftiin leh ama granule jaalle ah; dareerayaasha Newtonian (dareeraha Newtonian waxay tixraacaan dareeraha halkaasoo walaacu u dhigmayo heerka cadaadiska); Cufnaanta: 1.02 ilaa 1.20g/cm³; nuugista biyaha sare, falcelinta hydrolysis waxay ku dhici doontaa 230 darajo Celsius; nuugista biyaha PA46> PA6> PA66> PA1010> PA11> PA12> PA1212; Heerarka yaraanta weyn ee wax-soo-saarka.PP, PE> PA> PS, ABS.Hantida xannibaad dhexdhexaad ah iyo xannibaad xooggan oo xagga hawada ah.
Qalabka farsamada ee polyamid pa6
Qalabka farsamada ee polyamid pa6 guud ahaan waxay la xiriiraan crystallinity: Mar kasta oo crystallinity-ku sarreeyo, xoogga sare iyo adkeynta adag.Marka la eego xoogga, PC> PA66> PA6> POM> ABS.Xoojinta ayaa si weyn u saameeya hygroscopicity, heerkulka sarreeya, heerka sare ee hygroscopicity, hoos u dhigista xoogga jilicsan iyo sifooyinka kale.
Saamaynta adkaanta waxaa si weyn u saameeya waxqabadka hygroscopic.Kordhinta heerkulka, nuugista biyuhu way korodhaa, adkaantana way korodhaa.(Sida caadiga ah, adkaanta waa liidata marka ay jirto xaalad qalalan iyo heerkul hooseeya, waxayna u badan tahay in ay leedahay dildilaac ku yimaada alaabada birta ah iyo jabka jajaban ee 0 ℃.
Polyamid pa6 waxay leedahay dufan isku-duubni oo wanaagsan iyo iska caabin wanaagsan.
Iska caabin heer sare ah oo saliid ah, tusaale ahaan.batrool
Xoogga daalku aad buu u sarreeyaa, guud ahaan 20% ilaa 30% xoogga jilicsanaanta.Xoogga daalka ee PA6 iyo PA66 waxay gaari karaan ilaa 22MPa, ka labaad oo kaliya POM (35MPa) oo ka sarreeya PC (10-14MPa).Tixda marka la eego xoogga daalka: POM> PBT, PET> PA66> PA6> PC> PSF> PP.
Qalafsanaanta sare, PA66: 108 ilaa 120HRR;PA6120HRR.
Iska caabbinta gurguurta liidata: Way ka fiican tahay PP iyo PE, oo ka sii xun ABS iyo POM.
Iska caabbinta dildilaaca walaaca liidata: daawaynta huurka ama humidaynta waa in la sameeyaa ka dib markii la habeeyo alaabta.
