30% iav fiber reinforced PA6 hloov kho
30% iav fiber reinforced PA6 hloov nti yog cov khoom siv zoo tshaj plaws rau kev ua cov cuab yeej hluav taws xob lub plhaub, cov cuab yeej siv hluav taws xob, kev tsim kho tshuab thiab qhov chaw tsheb. Nws cov khoom siv kho tshuab, qhov ruaj khov, qhov kub thiab txias ua haujlwm tau zoo dua qub, thiab lub zog qaug zog yog 2.5 npaug ntawm qhov tsis zoo, thiab cov nyhuv hloov kho yog qhov pom tseeb tshaj plaws.
Kev txhaj tshuaj molding txheej txheem ntawm 30% iav fiber reinforced PA6 chips yog roughly tib yam li hais tias tsis muaj kev txhawb zog, tab sis vim hais tias cov ntws yog phem dua li ua ntej qhov cuab lub zog, txhaj tshuaj siab thiab txhaj tshuaj ceev yuav tsum tau nce kom tsim nyog. Cov ntsiab lus ua haujlwm yog raws li nram no:
1. Lub chim kub ntawm 30% iav fiber reinforced PA6 yog ib qho yooj yim kom nce los ntawm 10-40 ℃. Lub chim kub xaiv rau kev txhaj tshuaj molding ntawm PA6 hloov cov chips muaj feem xyuam rau cov khoom ntawm cov chips lawv tus kheej, cov khoom siv thiab cov yam ntxwv ntawm cov khoom. Cov khoom siv kub dhau heev yog ib qho yooj yim ua rau cov khoom hloov xim, nkig, nyiaj hlau thiab lwm yam tsis xws luag, qhov kub tsis tshua muaj siab yog ib qho yooj yim rau harden cov khoom thiab ua rau cov pwm thiab cov ntsia hlau puas. Qhov ntsuas kub qis tshaj plaws ntawm PA6 yog 220C. Vim nws zoo fluidity, nylon ntws sai heev thaum kub tshaj nws melting point. Lub fluidity ntawm 30% iav fiber reinforced PA6 hloov chips yog qhov qis dua li cov khoom siv ntshiab thiab qib PA6 chips, thiab lub thoob qhov kub yog qhov yooj yim los ntawm 10-20 ℃.
2. 30% iav fiber reinforced PA6 ua pwm kub yog tswj ntawm 80-120C. Cov pwm kub muaj qee yam cuam tshuam rau crystallinity thiab molding shrinkage, thiab qhov kub ntawm pwm yog 80-120 ℃. Cov khoom uas muaj phab ntsa tuab yuav tsum xaiv cov pwm kub, uas muaj crystallinity siab, zoo hnav tsis kam, nce hardness thiab elastic modulus, txo dej nqus thiab nce molding shrinkage. Nyias-walled cov khoom yuav tsum xaiv cov pwm kub uas tsis muaj crystallinity, zoo toughness, siab elongation thiab txo shrinkage. Yog tias cov phab ntsa thickness ntau dua 3 hli, nws raug nquahu kom siv cov pwm tsis zoo ntawm 20 ℃ txog 40 ℃. Cov pwm kub ntawm 30% iav reinforced khoom yuav tsum siab tshaj 80 ℃.
3. Cov phab ntsa tuab ntawm 30% iav fiber ntau ntxiv PA6 cov khoom yuav tsum tsis txhob tsawg dua 0.8mm. Qhov sib piv ntev ntawm PA6 yog nyob nruab nrab ntawm 150,200. phab ntsa thickness ntawm cov khoom yuav tsum tsis txhob qis tshaj li ntawm 0.8 hli. Feem ntau, qhov kev xaiv yog nyob nruab nrab ntawm 1 ~ 3.2 hli. Lub shrinkage ntawm 30% iav fiber reinforced PA6 khoom muaj feem xyuam rau nws phab ntsa thickness. Lub thickness ntawm phab ntsa, qhov ntau dua qhov shrinkage.
4. Lub qhov tso pa tawm yuav tsum tau tswj hauv qab 0.025mm. Tus nqi ntws dhau ntawm 30% iav fiber reinforced PA6 resin yog li ntawm 0.03mm, yog li lub qhov tso tawm yuav tsum tau tswj hauv qab 0.025mm.
5. Lub rooj vag txoj kab uas hla yuav tsum tsis pub tsawg tshaj 0.5 kilott (t yog lub thickness ntawm cov yas). Nrog rau lub rooj vag submerged, qhov tsawg kawg nkaus txoj kab uas hla ntawm lub rooj vag yuav tsum yog 0.75mm.
6. Lub shrinkage ntawm 30% iav fiber reinforced PA6 khoom yuav raug txo kom tsawg li 0.3%.
Lub shrinkage ntawm PA6 cov ntaub ntawv ntshiab yog nyob nruab nrab ntawm 1% thiab 1.5%, thiab cov shrinkage yuav raug txo kom txog li 0.3% tom qab ntxiv 30% iav fiber reinforcement. Kev ua tau zoo qhia tau hais tias qhov ntau iav fiber ntau ntxiv, qhov me me ntawm molding shrinkage ntawm PA6 resin yog. Txawm li cas los xij, nrog rau qhov nce ntawm cov fiber ntau, nws tseem yuav ua rau ntog fiber ntau, tsis zoo sib xws thiab lwm yam, 30% iav fiber reinforcement nyhuv yog qhov zoo.
7. 30% iav fiber reinforced PA6 recycled cov ntaub ntawv yuav tsum tsis txhob siv ntau tshaj 3 zaug. 30% iav fiber reinforced PA6 tsis muaj cov khoom siv rov ua dua tshiab, tab sis yog tias cov neeg siv khoom siv cov ntaub ntawv siv ntau dhau, nws yooj yim ua rau cov khoom tsis muaj xim lossis poob qis hauv cov khoom siv thiab lub cev, daim ntawv thov nyiaj yuav tsum tau tswj qis dua 25%, txwv tsis pub. nws yuav ua rau muaj kev hloov pauv hauv cov txheej txheem, thiab kev kho kom qhuav yuav tsum tau ua ua ntej cov khoom siv rov ua dua thiab cov ntaub ntawv tshiab sib xyaw.
8. Tus nqi ntawm cov pwm tso tawm tus neeg sawv cev yog me me thiab sib xws. Tus neeg sawv cev tso tawm ntawm 30% iav fiber reinforced PA6 cov khoom tuaj yeem xaiv zinc stearate thiab cov roj dawb, los yog nws tuaj yeem muab sib xyaw rau hauv paste, thiab ib qho me me ntawm tus neeg tso tawm tuaj yeem txhim kho thiab tshem tawm cov teeb meem xws li npuas. Kev siv yuav tsum yog me me thiab sib xws, thiaj li tsis ua rau muaj qhov tsis xws luag ntawm cov khoom.
9. Tom qab cov khoom tawm ntawm pwm, muab tso rau hauv dej kub kom txias maj mam. Vim hais tias cov iav fiber ntau yuav taw qhia raws li cov kev taw qhia ntws hauv cov txheej txheem txhaj tshuaj molding, cov khoom siv kho tshuab thiab shrinkage yuav txhim kho nyob rau hauv kev taw qhia, uas ua rau deformation thiab warping ntawm cov khoom. Yog li ntawd, nyob rau hauv cov pwm tsim, txoj hauj lwm thiab cov duab ntawm lub rooj vag yuav tsum tsim nyog. Qhov kub ntawm cov pwm tuaj yeem raug tsa hauv cov txheej txheem, thiab cov khoom yuav tsum tau muab tso rau hauv dej kub kom txias maj mam.
10. 30% iav fiber reinforced PA6 qhov chaw siv nyob rau hauv qhov kub thiab txias ib puag ncig yuav tsum moisturized. Cov av noo tswj txoj kev ntawm boiling dej los yog poov tshuaj diacetate tov yuav siv tau. Txoj kev tswj cov av noo ntawm boiling dej tso cov khoom ntawm cov av noo ntawm 65% kom ua tiav qhov sib npaug ntawm cov dej noo. Kev kho kub ntawm poov tshuaj acetate aqueous tov (qhov piv ntawm poov tshuaj acetate rau dej yog 1.2515, boiling point 121C) yog 80-100potassium acetate tov. Lub sij hawm kho feem ntau yog nyob ntawm cov khoom phab ntsa thickness, thaum phab ntsa thickness yog li 2 teev rau 1.5 hli, txog 8 teev rau 3 hli, thiab txog 16-18 teev rau 6 hli.
