Muaj ntau qhov sib txawv ntawm kev ua tau zoo ntawm qhov qis melting PET thiab PET zoo tib yam:
1. Melting point:
- Tsawg melting point PET: Lub melting point yog qis dua, feem ntau ncav cuag qhov kub ntawm 100-200 degree, piv txwv li, lub melting point ntawm ib co melting point PET yog 110-120 degree .
- Ordinary PET: Lub melting point yog feem ntau ntawm 250-255 degree .
2. Kev ua tau zoo:
- Tsawg melting point PET: Nws tuaj yeem yaj ntawm qhov kub thiab txias, thiab lub zog yuav tsum tau ua thaum ua haujlwm tsawg, uas tuaj yeem txo cov nqi tsim khoom. Nws muaj fluidity zoo dua ntawm qhov kub thiab txias, uas yog qhov zoo rau kev ua thiab molding, xws li yooj yim rau kev khiav lag luam hauv kev txhaj tshuaj molding, extrusion thiab lwm yam txheej txheem.
- Ordinary PET: Kev ua haujlwm kub yog qhov siab, thiab cov khoom siv thiab cov txheej txheem yuav tsum siab, thiab lub zog noj thaum ua haujlwm kuj tseem siab.
3. Mechanical zog:
- Tsawg melting point PET: Tom qab hloov kho, nws lub zog thiab lub zog yuav txawv nyob ntawm qhov kev hloov kho tshwj xeeb thiab txheej txheem. Qee qhov qis melting point PET yuav muaj qhov hloov tau zoo dua thaum tuav lub zog.
- Ordinary PET: Nws muaj lub zog siab thiab rigidity, lub zog tensile ntawm zaj duab xis yog piv rau cov ntawv txhuas txhuas, thiab nws muaj qhov zoo folding tsis kam, tab sis nws lub zog tsim kua muag thiab kev cuam tshuam tsis zoo.
4. Crystallization kev ua tau zoo:
- Tsawg melting point PET: Kev hloov pauv hauv cov qauv molecular yuav cuam tshuam rau nws cov crystallization kev ua tau zoo, crystallinity kuj yuav qis, lossis crystallization ceev yuav hloov.
- Ordinary PET: Cov qauv molecular yog symmetrical, muaj qee yam crystallization orientation peev xwm, thiab crystallinity kuj siab.
5. Hluav taws xob rwb thaiv tsev:
- Tsawg melting point PET: Nws tswj cov hluav taws xob zoo ntawm cov ntaub ntawv PET. Cov yam ntxwv no ua rau nws muaj qhov zoo ntawm daim ntawv thov hauv cov khoom siv hluav taws xob thiab tuaj yeem siv rau kev ntim khoom hluav taws xob, hloov hluav taws xob Circuit Court boards, thiab lwm yam.
- Ordinary PET: Nws kuj muaj cov hluav taws xob rwb thaiv tsev zoo heev, tab sis qee zaus qhov hluav taws xob rwb thaiv tsev kev ua tau zoo tshwj xeeb yog siab, qis melting point PET yuav muaj qhov zoo dua vim nws qhov kev ua haujlwm tshwj xeeb.
6. Compatibility nrog lwm yam ntaub ntawv:
- Tsawg melting point PET: tuaj yeem sib xyaw nrog PET zoo tib yam lossis lwm yam khoom siv sib txawv thiab txoj hauv kev kom ua tiav qhov kev xav tau thiab cov txiaj ntsig, thiab tuaj yeem ua ke nrog ntau yam khoom siv.
- Ordinary PET: Kev sib raug zoo nrog lwm cov ntaub ntawv yog qhov tsis zoo, thiab ntau cov txheej txheem kev kho mob thiab cov tshuaj ntxiv yuav tsum tau txhim kho.
compatibility thaum sib tov.
7. Daim ntawv thov teb:
- Tsawg melting point PET: Haum rau qee lub sijhawm uas ua rau qhov kub thiab txias ua haujlwm, xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob hloov pauv, lub hnub ci hlwb thiab lwm yam haujlwm; nyob rau hauv kev tsim fiber ntau, nws tuaj yeem siv los tsim cov khoom kub-kua fibers rau kev tsim cov ntaub ntawv tsis-woven, cov ntaub ntawv sib xyaw, thiab lwm yam, txhawm rau txhim kho kev sib raug zoo thiab ruaj khov ntawm cov ntaub ntawv, thiab tseem tuaj yeem siv rau hauv thaj chaw ntawm filaments thiab staple fibers los tsim ntau yam textiles, haum rau ntau yam lag luam xws li filaments, staple fibers, non-woven fabrics thiab khau ntaub.
- Ordinary PET: Feem ntau yog siv rau hauv ntim ntim, textile kev lag luam thiab engineering yas, xws li lub raj mis haus, zaj duab xis, hnab ntim khoom noj thiab textile fibers, thiab lwm yam, thiab tseem tuaj yeem siv los tsim cov khoom siv hluav taws xob, tsheb qhov chaw, khoom siv tshuab, thiab lwm yam. .
