Metode de testare a impactului filmului bazate pe ASTM D1709 \u0219i ASTM D3420<\/h2>

Standardele recunoscute la nivel mondial ASTM D1709<\/strong><\/a> \u015fi ASTM D3420<\/strong><\/a> definesc cele mai comune proceduri pentru evaluarea rezisten\u021bei la impact. Acestea \u00eendrum\u0103 cum s\u0103 se selecteze condi\u021biile de testare, s\u0103 se calculeze energia de rupere \u0219i s\u0103 se determine performan\u021ba diferitelor filme.<\/p>

Ma\u0219in\u0103 de testare a impactului ASTM D1709 ASTM D3420 Prezentare general\u0103 a metodei<\/h3>

Metoda pic\u0103turii de s\u0103ge\u021bi (ASTM D1709)<\/h3>

ASTM D1709 determin\u0103 energia necesar\u0103 pentru a provoca ruperea filmului \u00een condi\u021bii controlate s\u0103geat\u0103 \u00een c\u0103dere liber\u0103<\/strong> impact. Exist\u0103 dou\u0103 configura\u021bii:<\/p>

  • Metoda A:<\/strong>
    Cap hemisferic de s\u0103geat\u0103 de 38,10 \u00b1 0,13 mm
    \u00cen\u0103l\u021bime de c\u0103dere de 0,66 m
    Gama de mas\u0103 tipic\u0103: ~50 g p\u00e2n\u0103 la ~6 kg
    Ideal pentru folii de plastic cu grosime standard<\/li>
  • Metoda B:<\/strong>
    Cap hemisferic de s\u0103geat\u0103 de 50,80 \u00b1 0,13 mm
    \u00cen\u0103l\u021bime de c\u0103dere de 1,52 m
    Intervalul de mas\u0103: ~0,3 kg p\u00e2n\u0103 la ~6 kg
    Potrivit pentru filme mai dure sau mai groase<\/li><\/ul>

    Ambele proceduri se bazeaz\u0103 pe metoda sc\u0103rii (incremental\u0103)<\/strong>, care ajusteaz\u0103 masa s\u0103ge\u021bii \u00een func\u021bie de e\u0219ecul sau reu\u0219ita unui e\u0219antion.

    Metoda impactului cu pendul (ASTM D3420)<\/h3>

    ASTM D3420 utilizeaz\u0103 un ma\u0219in\u0103 de testare a impactului cu pendul<\/strong> pentru a m\u0103sura at\u00e2t energia de ini\u021biere, c\u00e2t \u0219i cea de finalizare, oferind detalii mai detaliate cu privire la tenacitatea filmului. Aceast\u0103 metod\u0103 completeaz\u0103 ASTM D1709 \u0219i ajut\u0103 inginerii s\u0103 compare comportamentele \u00een diferite dinamici de impact.<\/p>

    Cele dou\u0103 standarde nu sunt interschimbabile. Grosimea peliculei, geometria s\u0103ge\u021bii, \u00een\u0103l\u021bimea pic\u0103turii \u0219i viteza de impact influen\u021beaz\u0103 toate rezultatele. Prin urmare, datele testelor r\u0103m\u00e2n comparabile numai atunci c\u00e2nd toate variabilele respect\u0103 acela\u0219i standard.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

    actori care influen\u021beaz\u0103 performan\u021ba filmului la testul de impact<\/h2>

    Mai multe variabile influen\u021beaz\u0103 rezultatele \u0219i trebuie s\u0103 fie controlate pentru a ob\u021bine date exacte:<\/p>

    • Uniformitatea filmului:<\/strong> Varia\u021biile de grosime, marcajele matri\u021bei, incluziunile \u0219i contaminan\u021bii afecteaz\u0103 energia de defectare.<\/li>
    • Calitatea e\u0219antionului:<\/strong> Ridurile, g\u0103urile \u0219i pliurile denatureaz\u0103 m\u0103sur\u0103torile \u0219i trebuie eliminate, cu excep\u021bia cazului \u00een care fac parte din studiu.<\/li>
    • Cerin\u021be de condi\u021bionare:<\/strong>
      - 23 \u00b1 2\u00b0C temperatur\u0103
      - 50 \u00b1 10% umiditate relativ\u0103
      Condi\u021bionarea pentru cel pu\u021bin 40 de ore se aliniaz\u0103 standardului.<\/li>
    • Fixarea specimenului:<\/strong> Alunecarea poate invalida rezultatele. Echipamentul trebuie s\u0103 ofere o str\u00e2ngere ferm\u0103 \u0219i uniform\u0103.<\/li>

    • Precizia pic\u0103turii:<\/strong> Impactul s\u0103ge\u021bii trebuie s\u0103 loveasc\u0103 \u00een mod constant centrul suprafe\u021bei fixate.<\/p><\/li><\/ul>

      De ce se bazeaz\u0103 produc\u0103torii pe testarea impactului filmului<\/h2>

      Rezultatele testelor de impact ale filmelor ajut\u0103 organiza\u021biile:<\/p>

      • Evaluarea durabilit\u0103\u021bii ambalajelor \u00een condi\u021bii reale de stres mecanic<\/li>
      • Optimizarea formul\u0103rii \u0219i a proceselor de extrudare a filmelor<\/li>
      • Compara\u021bi performan\u021ba r\u0103\u0219inii, cum ar fi LLDPE, LDPE, PP sau filmele multistrat<\/li>
      • Stabilirea specifica\u021biilor \u0219i confirmarea conformit\u0103\u021bii<\/li>

        Deoarece rezisten\u021ba la impact nu se coreleaz\u0103 liniar cu grosimea, testarea corespunz\u0103toare devine esen\u021bial\u0103 pentru o evaluare precis\u0103.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
