LFT Yas Granule PBT Txhim Kho Cov Khoom Siv

Paub meej

LFT PBT Yas Granule yog ib qho ntawm cov ntaub ntawv tsim ua vaj tse thermoplastic muaj zog. Nws yog cov khoom siv semi-crystalline nrog kev zoo tshuaj lom neeg, lub zog kho tshuab, hluav taws xob rwb thaiv tsev thiab thermal stability. Semi-crystalline cov ntaub ntawv muaj kev nyab xeeb zoo nyob rau hauv ib puag ncig ntau ntawm ib puag ncig.
1.high cuam tshuam resisyance thiab siab toughness
2.creep retardanr thiab lub teeb yuag
3. rhiab-stability retardant.

LFT Yas Granule PBT Cov Khoom Uas Piav Ntau Lawm Cov Khoom Siv

Khoom Piav Qhia LFT PBT Yas Granule yog ib qho ntawm cov ntaub ntawv tsim ua vaj tse thermoplastic muaj zog. Nws yog cov khoom siv semi-crystalline nrog kev zoo tshuaj lom neeg, lub zog kho tshuab, hluav taws xob rwb thaiv tsev thiab thermal stability. Semi-crystalline cov ntaub ntawv muaj kev nyab xeeb zoo nyob rau hauv ib puag ncig ntau ntawm ib puag ncig.

1.high cuam tshuam resisyance thiab siab toughness

2.creep retardanr thiab lub teeb yuag

3. rhiab-stability retardant.

Cov cuab yeej hygroscopic ntawm PBT muaj zog heev. Lub zog tensile ntawm PBT tsis-txhim kho yog 50MPa, thiab hais tias ntawm lub iav ntev fiber ntau ntxiv PBT yog 170MPa.

Khoom Mob

Lub crystallization ntawm PBT yog nrawm, uas ua rau dabtsi yog khoov deformation vim tsis txias. Rau cov ntaub ntawv nrog iav additive hom, lub shrinkage nyob rau hauv cov kev taw qhia txaus tuaj yeem raug txo kom tsawg, tab sis cov shrinkage nyob rau hauv cov kev taw qhia ntsug ntawm cov kev taw qhia ntws yog qhov zoo ib yam li cov ntaub ntawv zoo tib yam. Lub shrinkage ntawm cov ntaub ntawv dav dav yog nruab nrab ntawm 1.5% ~ 2.8%, thiab cov shrinkage ntawm cov ntaub ntawv muaj 30% iav ntxiv yog nruab nrab ntawm 0.3% ~ 1.6%. Ob lub ntsiab lus npliag (225 ℃) thiab lub siab qhov kub deformation kub yog qis dua PET cov ntaub ntawv. Qhov ua kom kub dua ntawm vica yog li 170 ℃. Lub iav Trasitio kub li ntawm 22 ℃ txog 43 ℃. Vim lub siab crystallization tus nqi ntawm PBT, nws viscosity yog tsawg heev, thiab lub sijhawm lub sijhawm ntawm cov yas hloov khoom siv feem ntau yog qis.
