Yog tias koj tab tom nrhiav cov khoom siv rau lub tsev luam ntawv, TV bezels, lossis lub kaus mom kom zoo nkauj thiab koj tau hla cov ntsiab lus PA757K lossis abs 757k, ntawm no yog cov kab hauv qab: lawv xa mus rau tib yam khoom. Nyob rau hauv Chi Mei's POLYLAC® lineup, PA-757K yog Zhenjiang- tsim tawm version ntawm legendary "757" tsev neeg- siab-gloss txhaj molding ABS. Cov lus "K" tsuas yog qhia txog Zhenjiang cog; Lub formulation yog zoo tib yam rau Taiwan-ua PA-757. Tsis txhob poob rau qhov "K" txhais tau tias qis dua; tsom es tsis txhob ntawm cov batch COA thiab xyuas cov khoom yog nkauj xwb.
Chi Mei pib nrog ABS rov qab rau xyoo 1976. Hauv POLYLAC® series, PA-7xx npog dav dav- cov hom phiaj txhaj tshuaj qib. PA-757 tau dhau los ua tus qauv kev lag luam rau kev ntsuas nruj, gloss, thiab cuam tshuam-koj yuav pom nws nyob rau hauv yuav luag txhua vintage electronics enclosure. Thaum cov nroj tsuag Zhenjiang tuaj online nyob ib ncig ntawm 2002, lawv siv tib daim ntawv qhia tab sis ntxiv "K" kom paub qhov txawv keeb kwm. Yog li, txawm tias koj pom "abs 757k," "PA757K," lossis "757K ABS" hauv online, nws txhua tus taw qhia rau qib Zhenjiang tshwj xeeb.

FAQ:
Q1: Puas yog PA757K txawv ntawm "abs 757k"?
No. PA757K yog cov kev sau ntawv; "abs 757k" yog tus lej qis. Ob leeg xa mus rau qib Zhenjiang Chimei.
Q2: Puas tuaj yeem PA-757K hloov pauv Taiwan PA-757?
Mechanically, yog. Txawm li cas los xij, yog tias koj daim ntawv cog lus tus neeg siv khoom tau hais tias "Ua hauv Taiwan CHIMEI," koj yuav tsum siv PA-757. Peb tuaj yeem muab tau raws li koj qhov kev xav tau ua raws.
Q3: Puas yog PA-757K cov zaub mov tiv tauj zoo?
Lub ntuj resin muaj keeb kwm FDA ua raws cov ntaub ntawv, tab sis txhua pawg yuav tsum tau tshaj tawm tshwj xeeb. Thaum hloov kho (ua ntej-xim), cov khoom sib xyaw yuav tsum tau rov ua dua - kuaj kev nyab xeeb zaub mov.
Q4: Vim li cas 757K pheej yig dua 747 tab sis tseem siv rau vaj tse?
PA-747 yog qib siab- cuam tshuam (ntau Butadiene), uas txo qis gloss. PA-757K optimizes gloss thiab nruj thaum tuav "zoo txaus" cuam tshuam rau vaj tse. Nws tsis yog downgrading; nws yog txoj cai.
Q5: Koj puas tseem hu nws PA-757K tom qab ua ntej xim?
Kev lag luam xyaum hu nws "757K-raws li compound." Ntawm cov lus hais, peb sau nws li "PA-757K pre-coloured compound" kom paub qhov txawv ntawm cov khoom siv nkauj xwb.
Q6: Vim li cas qee cov ntaub ntawv qhia MFR li 1.8 thiab lwm tus li 18?
Ob leeg yog lawm; lawv siv cov kev xeem sib txawv . 1.6–1.8 g/10min yog sim ntawm 200℃/5kg. 18 g/10min yog sim ntawm 220℃/10kg. Nco ntsoov xyuas cov qauv ntsuas ua ntej muab cov lej sib piv.
Vim li cas cov neeg yuav khoom nrog PA-757K
Nws tsis tshua muaj qhov pheej yig tshaj ib tuj. Nws yog hais txog Tus Nqi Tag Nrho Cov Tswv Cuab. PA-757K txuag nyiaj los ntawm kev tshem tawm cov duab kos, txo cov pwm hloov lub sij hawm vim muaj kev sib hloov qis, thiab tiv thaiv QC kev tsis sib haum xeeb los ntawm kev sib koom ua ke. Rau cov chaw tsim khoom tsim TV bezels lossis ntim cov tshuaj pleev ib ce, cov khoom siv uas tso cai rau Tus Thawj Saib Xyuas Kev Lag Luam tawm raws sijhawm thiab Tus Thawj Saib Xyuas Muag Khoom kos npe cog lus ntseeg siab muaj nqis ntau dua li txuag $ 20 / tuj ntawm cov khoom tsis raug.
