Tsis ntev dhau los, cov khoom siv tshiab tuaj yeem pom ntawm kev lag luam hauv tsev ntawm cov khoom ntim - polyethylene ua npuas ncauj. Nws muaj cov yam ntxwv ua tau zoo uas tau tso cai rau nws los ua cov khoom ntim nrov heev. Nws tau txais txiaj ntsig los ntawm ob tus kws tshaj lij kev tsim kho thiab cov neeg nyiam ua haujlwm zoo tib yam.

Nws zoo li cas?

Polyethylene ntawm pab pawg no zoo kawg nkaus nrog nws txoj haujlwm ua lub cushioning thiab ntim khoom. Feem ntau, cov haujlwm zoo li no yuav tsum muaj nyob rau hauv cov xwm txheej uas tsim cov khoom thauj khoom. Foamed polyethylene muab kev tiv thaiv ntxiv rau cov khoom thauj los ntawm cov av, ya raws thiab kev puas tsuaj. Npuas qhwv feem ntau siv nrog nws txhawm rau txhawm rau tiv thaiv thaum nws xav tau tiag tiag.

Ntawm cov khoom thiab nws ntau yam

Kom tau txais cov khoom xws li foamed polyethylene, polymerization yog npaj rau cov ethylene zoo tib yam. Raws li qhov tshwm sim ntawm qhov notxheej txheem, cov khoom ib feem crystallizes. Nws yog ua tsaug rau qhov tau txais cov qauv zoo li no uas cov khoom khaws cia cov dej noo txawm nyob ntawm 130 degrees, thiab tseem ua tau zoo dua tiv thaiv ib puag ncig cuam tshuam.

Cov khoom siv los ntawm lub cev muaj zog

Lub cev sib txuas thiab tshuaj sib txuas sib txuas - hauv lub cev no, foamed polyethylene tau nthuav tawm hauv khw niaj hnub no. Yog tias peb tab tom tham txog kev ntim khoom, tom qab ntawd nrog qhov tshwm sim siab nws yuav yog lub cev crosslinked polyethylene. Lub thickness ntau ntawm no ntau yam yuav txawv ntawm tsib feem kaum mus rau nees nkaum millimeters. Txawm hais tias kev hloov pauv hauv qhov ntom ntom tseem me me. Kom txhua tus neeg siv khoom tuaj yeem dhau los ua tus tswv ntawm cov ntim khoom zoo uas ua tau raws li cov kev cai tshwj xeeb ntawm ib tus neeg.

Hais txog tus yam ntxwv

Muaj ntau tus yam ntxwv uas ua rau polyethylene ua npuas ncauj thiaj li nrov. Tus nqi ntawm cov khoom yuav ncaj qha nyob ntawm qhov zoo. Yog li, yam ntxwv:

  • tsis-allergenic, ib puag ncig tus phooj ywg;
  • durability thiab durability;
  • tsis nkag siab rau qhov kub thiab txias hloov;
  • qis abrasive;
  • cushioning zoo heev;
  • resistance rau deformation;
  • qis thermal conductivity;
  • dej resistant;
  • yoog tau, khov kho thiab elasticity.

Nqaij thiab kab tsis ua mob rau cov khoom zoo li no. fungus, pwm thiabKev raug tshuaj lom neeg kuj tsis txaus ntshai. Lub kaw cellular qauv yog ib qho tseem ceeb ntawm cov khoom siv xws li polyethylene ua npuas ncauj. Lub thickness ntawm cov khoom siv tau xyaum tsis cuam tshuam rau nws lub peev xwm zoo heev los ua ib qho zoo insulator thiab muaj peev xwm ua kom noo noo thiab chav tawm, txawm tias nyob rau hauv ntau qhov ntau. Yog hais tias thaum lub sij hawm thauj khoom cov khoom khib nyiab tau rau ntawm qhov chaw los yog qhov chaw nyob ze, ces nws yog foamed polyethylene uas yuav coj cov tshuaj no ntawm nws tus kheej. Yog li ntawd, cov khoom nws tus kheej yuav tsis raug rau cov neeg kho tshuab puas.
