Khoom cua nyom yog ua ntau thiab nrov dua. Xijpeem hauv cov chaw pej xeem lossis hauv cov tsev ntiav, lawv tshwm sim hauv cov neeg' s lub zeem muag ntau zaus. Txawm li cas los xij, koj puas paub yuav ua li cas xaiv cov nyom hluavtaws tsis haum thaum ntsib nrog ntau yam ntawm cov khoom cua dag? Tam sim no peb cov khoom siv dag ntawm cov nyom, uas yog nylon, polyethylene (PE), thiab polypropylene (PP).

Nylon

Nylon yog ib tug qub tub rog ntawm cov nyom nyom. Nws yog thawj cov khoom siv los siv rau kev nyom. Nws muaj nws cov laj thawj zoo. Nylon tau siv los tsim cov kaus poom hauv ntiaj teb Tsov Rog Zaum Ob vim tias nws yog cov khoom siv khov kho. Hais txog kev siv nws ua hluavtaws nyom, nws siv tau vim tias nws tuaj yeem tiv taus kev hnav thiab tsim kua muag ntawm thaj chaw muaj ntau dua, xws li chaw ua si lossis thaj chaw tsiaj. Nws tuaj yeem hais tias nylon yog qhov zoo tshaj plaws nyom nyom dag cov nyom tsuav nws tus nqi yuav qis dua.
Ntau lub tuam txhab xaiv nylon vim tias cov nyom ziab sawv siab dua thiab muaj kev ncaj ncees dua li lwm hom nyom dag, tib lub sij hawm khaws zoo siab xav taug kev. Txawm hais tias tom qab raug huab cua hnyav thiab hnyav hnyav, nylon nyom hniav yuav ua rau lawv lub cev qub. Lawv kuj tseem tuaj yeem nqus cov kua dej tau yooj yim, uas ua rau qhov zoo tshaj plaws hauv thaj chaw ntawm tus kheej.

Polypropylene (PP)

Cov nyom dag ua los ntawm cov khoom siv no yog qhov tsis tshua kim tshaj plaws ntawm cov nyom hluavtaws. Tab sis ntawm qhov tsis sib xws, nws tsis tuaj yeem tiv taus ntau qhov kev puas tsuaj thiab muaj lub ntsiab lus melting. Tsis zoo li nylon, PP tsis nqus dej yooj yim thiab yuav hnav zoo dua li sai dua. Txawm hais tias cov khoom siv no muaj qhov tsis txaus, nws yog qhov tseem tsis yog qhov kev xaiv tsis zoo rau cov neeg ntawm cov peev nyiaj qis dua thiab rau cov neeg uas tsuas yog saib rau nruab nws rau hauv cov chaw me me, xws li tso ntsuab, lossis lwm qhov chaw muaj cov haujlwm tsawg.

Polyethylene (PE)

Koj tuaj yeem pom cov khoom siv no hauv cov khoom lag luam yas xws li cov fwj tshuaj ntxuav tes lossis hnab muag khoom noj qee zaum. Raws li qhov tau siv los ua hom nyom dag, PE pom muaj nyob hauv kev ua kis las, zoo li cov ntawd rau kev ncaws pob thiab ncaws pob. Nws yog qhov tseeb tiag tiag ntawm peb cov ntaub ntawv no, uas ua rau nws muaj qhov xav tau ntawm ntau tus neeg uas mus rau kev zoo nkauj ntawm cov nyom zoo, huv nyom. Ntawm txhua txoj xov siv nyob rau ntau hom hluavtaws hluavtaws, PE yog qhov zoo ib yam thiab pom zoo li qhov tiag.

Rau ib tus neeg ntawm cov peev nyiaj qis dua, uas tab tom nrhiav kom muaj cov nyom me me coj los siv rau hauv qhov chaw uas muaj kev ua haujlwm tsawg, polypropylene yuav yog qhov kev xaiv zoo. Ib tus neeg uas txaus siab siv nyiaj ntau dua rau cov nyom tab sis xis nyiam yuav nyiam tshaj plaws nrog nylon. Polyethylene yuav zoo tagnrho rau ib tus neeg tab tom nrhiav txhim kho nyom nyom hauv cov chaw ua haujlwm siab, zoo li cov chaw ncaws pob.
