Cov Khoom Siv Hnab Cov Khoom Siv Rau Cov Khoom Siv Kom Plymmetic

Cov thawv ua kom zoo nkauj yog qhov tseem ceeb ntawm kev ntim khoom kom zoo nkauj, pabcuam rau kev tiv thaiv thiab kho kom zoo nkauj. Cov Khoom Siv Rau Cov Khoom Pleev Hniav suav nrog:

1. Polyethylene (PE)

Polyethylene yog ib qho ntawm feem ntau dav siv plastics hauv kev lag luam niaj hnub. Nws tus nqi ntau lawm thiab tshuaj lom neeg lub cev thiab tshuaj lom neeg, tshwj xeeb heev rau cov roj qaub thiab UV hluav taws xob, ua rau nws cov khoom nrov rau cov khoom siv kom pleev xim.

2. Polypropylene (PP)

Polypropylene yog ib lub thermoplastic nrog lub cev zoo, qauv qauv, corrosion tsis kam, thiab ua cov khoom. Nws yog dav siv hauv ntim yas, tshwj xeeb yog hauv kev tsim cov khoom siv kom hniav zoo nkauj. Piv rau polyethylene, polypropylene muaj qhov zoo dua siab dua- kub ua thiab yog tsawg dua rau kev deformation.

3. Polyesters

Cov no suav nrog tsiaj (polyethylene terephthalate) thiab cwj mem (polyethylene terepthalate {}} naphtalene diol). Cov thawv kom hniav ua los ntawm cov ntaub ntawv no muaj cov khoom siv lub cev siv hluav taws xob thiab tshuaj lom neeg, thiab zoo hloov pauv rau cua sov, acid, thiab alkali corrosion.

4. Polystyrene (PS)

PS yog ib qho kev lag luam, insulating, thiab nplaim - retardant yas, kuj tseem siv hauv kev ntim kom zoo nkauj. Thaum feem ntau pob tshab, ps kuj los hauv ntau cov xim thiab qib qib. Nws yog ib qho yooj yim rau cov txheej txheem thiab pwm, thiab cov pheej yig.
