Tsib tsib daim ntaub ntawv ntawm PBT cov ntaub ntawv

PBT yog ib qho ntawm qhov tseeb thiab ceev tshaj plaws-cog ntau hom ntawm cov khoom siv hlau hauv cov khoom lag luam. Nrog nws cov kev kawm zoo tag nrho, zoo moldability thiab kev ua tau zoo, cov khoom siv zoo heev, kev kho siab zog, kev qaug zog thiab dimensional stability, Hloov me me. Cov khoom no tsis tshua hloov pauv thaum kub kub, zoo tagnrho rau kev tsav tsheb, hluav taws xob thiab lwm yam, thiab hnub no peb to taub daim ntawv thov PBT cov ntaub ntawv.

Ua ntej, keeb kwm kev loj hlob

1942 Cov kws tshawb fawb German P.Schlack tau tsim rau PBT cob, tom qab lub Teb Chaws Asmeskas Celanese Corporation (tam sim no Ticona) rau kev tsim kho, tau teev nyob rau hauv lub npe Celanex lub npe

1970 30% iav fiber reinforced yas rau lub khw, lub npe trade X-917, tom qab hloov mus rau CELANEX

1971 Eastman lub tuam txhab tau pib siv cov iav fibre reinforced 琏 thiab cov khoom tsis-muaj zog, npe cov npe Tenite (PTMT)

1971 GE lub tuam txhab tseem tsim cov khoom zoo sib xws, tsis muaj li, ua kom pom thiab tua tus kheej ntawm peb ntau yam.

Tom qab ntawd lub ntiaj teb nto moo manufacturers German BASF, Bayer, lub tebchaws United States GE, Ticona, Nyiv Toray, Mitsubishi Tshuaj, Taiwan Shin Kong Fibers, Changchun, South Asia Plastics thiab lwm cov tuam txhab tau muab tso rau hauv cov qib ntawm cov khoom.

Thib ob, qhov kev ua tau zoo

1. Zoo:

Cov khoom siv zoo heev, tshwj xeeb tshaj yog cov rigidity thiab hardness

Zoo tshav kub kub, tshav kub distortion kub txog li 180 ℃

Kev ua kom zoo zog, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob thiab hluav taws xob

Kev ceev crystallization ceev, zoo fluidity, zoo moldability

Zoo thermal stability, hauv particular, muaj ib qis tus nqi ntawm thermal expansion thiab loj ntsws

Zoo tsis ua hauj lwm rau cov tshuaj, cov kuab tshuaj, huab cua

High dielectric zog, zoo hluav taws xob zog

Tsawg hygroscopicity, tsawg feem ntawm kev ruaj ntseg thiab dimensional stability

2. Cov tsis zoo:

Cov molecules muaj ester bonds, uas decompose nyob rau hauv qhov kev txiav txim ntawm cov acids, cov hauv paus thiab dej vapor

Khoom siv yog ntau nkag rau qhov sib txawv, muaj ib qho phenomenon nkig

Thib peb, hloov

1. Txhim khu qhov hloov kho

Hauv PBT ntxiv iav fiber, iav fiber ntau thiab PBT cov ntaub qhwv tsev zog, PBT resin nyob rau hauv ib qho nyiaj ntawm cov iav fiber ntau, tsis tsuas yog muaj peev xwm tswj tau cov tshuaj PBT tshuaj, ua haujlwm thiab lwm yam zoo, tab sis kuj muaj ntau dua Kev txhim kho nws cov khoom vaj khoom tsev, thiab kov yeej lub PBT resin qhov txawv txav.

2. Hloov kho hluav taws xob rov qab

PBT yog crystalline uas muaj ntxhiab polyester, yog tias tsis ntxiv nplaim hluav taws, qhov hluav taws kub nyhav qib siab yog UL94HB qib, tsuas yog siv cov nplaim hluav taws xob tuaj, kom ncav qib UL94V0.

Feem ntau siv cov nplaim hluav taws kub yog cov bromides, Sb2O3, phosphides thiab chlorides thiab lwm cov khoom halogen nplhaib, feem ntau yog decabromodiphenyl ether, nws yog ib tug PBT nplaim hluav taws retardants, tiam sis vim yog vim li cas, Cov teb chaws yoojyim heev Nws yog txwv thiab tag nrho ob tog saib rau lwm txoj kev tab sis yeej tsis tau muaj kev ua tau zoo tshaj kev ua kom zoo rau decabromodiphenyl ether.

3. Mixed alloy hloov

Lub hom phiaj tseem ceeb ntawm PBT tau sib tov nrog lwm cov polymers: los txhim kho lub zog ntawm lub zog, uas ua kom lub suab sib deev tshwm sim los ntawm kev sib zog thaum sib sau thiab txhim kho cov cua kub.

Muab cov plhaws los siv hauv tsev thiab txawv teb chaws los hloov nws. Tuaj hloov pauv rau PBT polymer PC, Tus tsiaj ntawv, thiab lwm yam. Cov khoom xws li no yog siv hauv tsheb, tshuab hluav taws xob, cuab yeej hluav taws xob, iav fiber ntau nyob rau hauv ntau hom, thiab nws qhov chaw siv kuj txawv.

Plaub, daim ntawv thov

1.Car

Nrog lub nrov ntawm qhov kev tsav tsheb, kev ua haujlwm ntawm cov qauv hauv kev siv automotive tseem ntau thiab ntau dua, PBT yog ib yam ntawm cov khoom siv hlau nrog nws cov khoom siv zoo heev, txhua yam muaj zog, kev qaug zog thiab kev ruaj ntseg thiab lwm qhov zoo hauv lub tsheb Daim ntawv thov tseem dav heev.
