Cov Khoom Siv Yas Tshaj Nrog Kev Lag Luam Laser Vuam Technology

Cov hauv qab no yog cov kev tsom xam yas ntawm cov khoom siv yas tau tshaj nrog cov thev naus laus zis, sib txuas cov ntaub ntawv tshawb fawb ntau ntxiv:

Kuv {.} Kev faib tawm thiab cov yam ntxwv ntawm cov ntaub ntawv tsim nyog **

{{01. thermoplastic polymer evrix

- Polypropylene (PP)

Kev nkag mus rau Vuam Vuam tuaj yeem ua tiav los ntawm kev puas tsuaj loj, yog tias tsis muaj kev puas tsuaj rau kev nqus cov qauv zoo nkauj (xws li siv lub zog ua kom zoo dua li 1 hli

- Polycarbonate (PC)

Nws muaj siab transporency, kev cuam tshuam tsis kam thiab thermal ruaj khov los ntawm cov khoom siv fiber ntau dua tshiab, tshwj xeeb yog xav tau kho qhov muag tau kho qhov muag theej,

- Polyamide (PA6 / PA12)
Carbon Fiber txhawb cov tshuaj polyamide (xws li hygroscococide pab txo qhov tsis taus pa hluav taws xob}

2.} Engineering Plastics Thiab Composites
- Polyphenylene sulfide (PPS)
Semi-Crystalline Thermoplastic, Kub tiv taus ntawm cov khoom lag luam roj ntsha tau txais Laser Cov Lus Qhia Thaum Tshav Kub Kub {}}
- ** POLYHETHETKE (PEEK) **
Kev nthuav tawm zoo tshaj plaws (343 degree) thiab kev kawm tshav dav hlau tau ua kom tsis txhob muaj thermal txwv kev lag luam {}}

 

Thib ob, qhov tseem ceeb technical tsis rau cov khoom xaiv
{{0 {}} qhov kev nqus tau zoo
- Lub zog ntawm co₂ laser (wavelength 10.}}}}} paab cov pawg (xws li PP), graphene graphene (xws li cov khoom siv kub (xws li pob tshab kub).
- ob-sab mesoporous polymer / graphene heterostructures thiab zoo rau kev ua kom zoo linision vuam ntawm micrro li {}}

2. Kev coj cwj pwm thiab crystallinity
- lub suab nrov-recrystallization ntawm semi-crystalline cov ntaub ntawv (waverength)
- amorphous cov ntaub ntawv (xws li pc) tsis muaj lub ntsiab yaj yaj yaj, yog li lub qhov rai vuam yuav tsum tau tswj hwm los ntawm cov iav hloov ntsuas kub (tg) kom tiv thaiv cov khoom ua rau.

{{0 {{}} kev cuam tshuam ntawm kev txhawb nqa cov fibers
- Laser Vuam ntawm Carbon Fiber txhawb cov khoom sib xyaw (CFRP) yuav tsum muaj kev cuam tshuam nrog kev cuam tshuam fiber ntau thiab kev cuam tshuam nrog kev cuam tshuam fiber ntau thiab kev cuam tshuam nrog lub zog nqus {}

Iii {. txheej txheem txhim kho kom zoo
1. laser parameter tswj
- wavelength tuning (xws li lub tunable bol
- Lub zog hluav taws xob ceev thiab ntsuas qhov nrawm xav tau kom sib phim ntawm cov khoom siv hluav taws xob ntawm cov khoom los tiv thaiv kev kub ntxhov (xws li PA6).

{{0 {}}} ** Tsim kev tsim qauv thiab cov thev naus laus zis tshuab
- kev siv ntawm pob tshab cua pob tshab (xws li Quartz iav) tuaj yeem nrawm nrawm nrawm nrawm, uas yog tsim nyog rau vuam nyias txheej ntawm cov ntaub ntawv .
- preheating lossis tom qab kev kho mob (xws li cua sov infrared) tuaj yeem txhim kho cov int interrayer muaj zog, tshwj xeeb tshaj yog rau cov fiber ntau cov ntsiab lus composites.

1.} tus mob zoo
- lub teeb ci ntsa iab: Laser-welded Pa6- cms in dua kev txhaj tshuaj molding {}}
- Hloov cov khoom siv hluav taws xob: Polyester-SpandEX cov ntaub ua tiav kev ua haujlwm siab (4ω / cm) los ntawm Laser Kev Ntsuas Cov Khoom Siv Nyiaj Ncaj Ncees, Tsim nyog rau Smart Troftors.

2. badlenecks
- Cov ntaub ntawv hais tau zoo (xws li txhuas hmoov puv thawm) yuav tsum muaj kev txhim kho ntawm kev tiv thaiv kev tiv thaiv tshuab {}}
- Qhov sib txawv hauv kev nthuav dav ci coefficient ntawm dissimilar polymers nyob rau hauv ntau-khoom siv vuam tuaj yeem yooj yim coj los cuam tshuam rau kev cuam tshuam rau kev cuam tshuam rau kev cuam tshuam rau interfacial.

 

Lub ntsiab
Kev xaiv cov ntaub ntawv rau co₂ laser vuam siv thev naus laus zis thiab siv cov khoom siv hluav taws xob hloov kho tshiab los nthuav cov khoom lag luam tshiab; ② Txhim kho cov vuam qhov tsis sib xws ua ke nrog tshuab kev kawm; ③ Tshawb nrhiav lub peev xwm rau kev coj ua ntawm cov khoom microstructure los ntawm cyclic lub tswv yim {}}
