Polyethylene yas yog polyethylene ua cov khoom tseem ceeb

Cov khoom tseem ceeb ntawm polyethylene yas yog polyethylene. Nws cov khoom siv raw ethylene feem ntau yog los ntawm cov roj av tawg thiab tawg, uas yog cov khoom siv petrochemical.

polyethylene (PE) yog ib qho ntawm tsib qhov tseem ceeb hluavtaws cob, thiab nws yog ntau yam nrog lub peev xwm loj tshaj plaws thiab qhov loj tshaj plaws ntshuam ntim ntawm cov hluavtaws cob hauv kuv lub tebchaws. Polyethylene feem ntau muab faib ua peb pawg: linear low-density polyethylene (LLDPE), low-density polyethylene (LDPE), thiab high-density polyethylene (HDPE).

Daim ntawv thov

Yas qhwv, hnab tshos-style hnab yas, hnab yas khoom noj khoom haus, me nyuam lub raj mis, pails, lub raj mis dej, thiab lwm yam.

Yam ntxwv

PE yog qhov muag muag thiab muaj qhov zoo nkauj zoo nkauj rau qhov kov. Piv nrog rau tib cov yas, nws yog qhov sib dua ntawm qhov hnyav thiab muaj qee qhov kev pom tseeb. Thaum nws kub hnyiab, nplaim taws yog xiav.

Toxicity

Non-toxic thiab harmless rau tib neeg lub cev.

Cov khoom siv rau polyethylene yas

Corrosion kuj, zoo heev hluav taws xob rwb thaiv tsev (tshwj xeeb tshaj yog high-frequency rwb thaiv tsev), muaj peev xwm yuav chlorinated, irradiated thiab hloov kho, thiab yuav tsum tau ntxiv nrog iav fibers. High-density polyethylene muaj lub siab melting point, rigidity, hardness thiab lub zog, thiab tsis tshua muaj dej nqus. Cov khoom hluav taws xob zoo thiab hluav taws xob tiv thaiv; low-density polyethylene muaj zoo softness, elongation, cuam tshuam lub zog thiab permeability; ultra-high molecular hnyav polyethylene muaj qhov cuam tshuam lub zog, qaug zog thiab hnav tsis kam. High-density polyethylene yog tsim rau Nws tuaj yeem siv los ua cov khoom tiv thaiv corrosion thiab insulating qhov chaw; low-density polyethylene yog tsim los ua cov yeeb yaj kiab, thiab lwm yam .; ultra-high molecular hnyav polyethylene yog tsim rau kev poob siab absorbing, hnav-resistant thiab kis tau tus mob qhov chaw.
