Siab thiab tsis kub tsis kam ntawm kub yaj nplaum zaj duab xis

Qhov kub thiab tsis kub tsis kam ntawm kub yaj nplaum zaj duab xis yog ib qho tseem ceeb ntawm kev ua tau zoo thiab muaj kev cuam tshuam loj heev los ntawm cov hauv qab no.

1. Cov tshuaj muaj pes tsawg leeg ntawm zaj duab xis nws tus kheej

Hom Polymer: Kev ua haujlwm ntawm cov nplaum nplaum nplaum ua los ntawm cov polymers sib txawv heev. Piv txwv li, polyamide (PA) kub yaj nplaum zaj duab xis muaj qhov kub thiab txias tsis kam. Qhov no yog vim hais tias cov amide bonds nyob rau hauv nws cov molecular saw ua rau lub intermolecular quab yuam muaj zog, thiab cov molecular saw kuj tseem ruaj khov nyob rau hauv high kub, thiab muaj peev xwm tiv taus kub ntawm 180-220 degree. Txawm li cas los xij, cov saw hlau molecular ntawm ethylene-vinyl acetate (EVA) kub yaj nplaum zaj duab xis yog qhov hloov tau yooj yim, thiab cov saw hlau molecular yog yooj yim rau xaub ntawm qhov kub thiab txias. Nws yuav soften thiab ua nplaum nyob ib ncig ntawm 80-100 degree . Thermoplastic polyurethane (TPU) kub yaj nplaum zaj duab xis muaj qhov kub thiab txias tsis kam. Nws cov molecules yog tsim los ntawm cov ntu tawv thiab ntu mos. Cov ntu mos muab kev hloov pauv tau zoo thiab tseem tuaj yeem tuav elasticity ntawm -20--40 degree .

Cov khoom xyaw ntxiv: Cov additives ua lub luag haujlwm tseem ceeb hauv qhov kub thiab txias tsis kam. Antioxidants tuaj yeem tiv thaiv kub yaj nplaum zaj duab xis los ntawm oxidative degradation ntawm qhov kub thiab txias. Nyob rau hauv ib puag ncig kub, antioxidants ntes cov dawb radicals, inhibit oxidation cov tshuaj tiv thaiv, thiab ncua lub neej kev pab cuam ntawm zaj duab xis. Plasticizers tuaj yeem txhim kho qhov yooj yim ntawm qhov kub thiab txias, tab sis qhov sib ntxiv ntau dhau yuav ua rau cov yeeb yaj kiab muag muag thiab ntws ntawm qhov kub thiab txias, txo qhov kub tsis kam.

2. Lub cev muaj zog ntawm zaj duab xis

Thickness: Lub thickness ntawm cov zaj duab xis muaj feem xyuam rau lub tshav kub tsis kam. Thicker films hloov cua sov kuj maj mam, uas tuaj yeem ncua cov txheej txheem softening ntawm qhov kub thiab txias. Piv txwv li, nyob rau tib qhov kub thiab txias, 1mm tuab zaj duab xis tuaj yeem tiv taus qhov kub thiab txias zoo dua li 0.1mm tuab zaj duab xis.

3. Cov yam ntxwv ntsig txog kev thov

Cov khoom siv sib khi: Qhov sib txuam ntawm cov thermal expansion coefficient ntawm cov khoom sib txuas thiab cov nplaum nplaum yog qhov tseem ceeb. Yog tias qhov thermal expansion coefficients ntawm ob qhov sib txawv heev, qhov kev ntxhov siab loj yuav raug tsim tawm ntawm qhov sib cuam tshuam thaum qhov kub hloov pauv. Piv txwv li, thaum sib txuas cov hlau thiab yas, ntawm qhov kub thiab txias, vim qhov sib txawv ntawm thermal expansion coefficients, cov nplaum zaj duab xis interface yuav ncav cuag los yog nyem, uas yuav ua rau debonding thiab cuam tshuam rau qhov kub thiab txias.

Cov txheej txheem Bonding: Cov txheej txheem kev sib khi yog qhov tsim nyog los xyuas kom meej qhov kub thiab txias tsis kam. Yog tias cov yeeb yaj kiab thiab cov khoom siv tsis sib koom ua ke thiab muaj qhov sib txawv ntawm huab cua thaum lub sij hawm sib txuas, cov huab cua nthuav dav ntawm qhov kub siab yuav ua rau cov yeeb yaj kiab sib cais ntawm cov khoom siv. Kev sib raug zoo siab tuaj yeem ua rau cov yeeb yaj kiab sau cov pores ntawm cov khoom siv, txhim khu kev sib raug zoo thiab kub ua haujlwm. Lub sijhawm cua sov tsis txaus yuav ua rau muaj kev sib txuas tsis txaus, uas ua rau muaj teeb meem thaum kub hloov pauv.
