PS phab ntsa vaj huam sib luag yog dab tsi?

Cov khoom siv PS yog polystyrene.

Polystyrene yog ib hom thermoplastic uas muaj cov khoom rwb thaiv tsev zoo heev thiab ua tau zoo. Nws yog ib hom khoom siv polymer tshiab uas tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis ua rau ib puag ncig puas tsuaj. Cov hauv qab no yog hais txog polystyrene.

1、 Cov Lus Txhais Tseem Ceeb

Polystyrene yog ib qho polymer uas tsim los ntawm kev sib xyaw ua ke ntawm styrene monomers. Nws muaj kev pom tseeb thiab kev cuam tshuam, yog li nws siv dav hauv kev tsim ntau yam thawv, cov ntaub ntawv ntim khoom, thiab cov ntaub ntawv tiv thaiv. Tsis tas li ntawd, PS cov ntaub ntawv kuj muaj kev ruaj khov tshuaj zoo thiab tuaj yeem tiv taus kev yaig ntawm ntau yam tshuaj lom neeg.

2, Cov Ntawv Thov

Vim nws cov khoom siv lub cev thiab tshuaj zoo heev, polystyrene muaj ntau yam kev siv hauv ntau qhov chaw. Piv txwv li, hauv kev tsim vaj tsev, nws yog siv los ua ntau yam kav dej, phab ntsa vaj huam sib luag, thiab cov ntaub ntawv rwb thaiv tsev phab ntsa sab nraud. Hauv kev ntim khoom, vim nws muaj peev xwm ua tau zoo heev thiab tiv taus kev cuam tshuam, nws yog siv dav hauv kev tsim cov thawv ntim khoom thiab cov khoom ntim sab hauv. Tsis tas li ntawd, cov ntaub ntawv PS yog siv dav hauv cov chaw xws li cov khoom siv hluav taws xob, cov khoom ua si, thiab kev tsim khoom siv tsheb.

3, Cov yam ntxwv thiab qhov zoo

Polystyrene muaj cov yam ntxwv tseem ceeb hauv qab no:

1. Muaj kev pom tseeb thiab pom kev zoo.

2. Yooj yim rau kev ua thiab tsim khoom, muaj peev xwm ua tau raws li qhov xav tau ntawm ntau yam duab sib txawv.

3. Muaj zog tiv taus kev cuam tshuam, muaj peev xwm tiv taus qee qhov kev nyuaj siab thiab kev cuam tshuam.

4. Kev ruaj khov tshuaj zoo, muaj peev xwm tiv taus kev yaig ntawm ntau yam tshuaj lom neeg.

5. Tus nqi qis dua, nrog rau kev siv nyiaj zoo.

Hauv kev xaus lus, cov khoom siv PS yog ib qho thermoplastic tseem ceeb nrog ntau yam kev siv hauv ntau qhov chaw. Vim nws qhov kev ua tau zoo heev thiab tus nqi qis, polystyrene tuav txoj haujlwm tseem ceeb hauv kev ua lag luam.
