Polypropylene Vs. PVC: Yam twg zoo dua?

1. Polypropylene vs PVC

Thaum nws los txog rau cov ntaub ntawv hloov tau, ob lub npe uas peb nquag hnov ​​yog Polypropylene (PP) thiab Polyvinyl Chloride (PVC). Ob qho khoom siv no kuj muaj ntau qhov sib xws thiab qhov sib txawv.

1.1. Polypropylene yog dab tsi?

PP yog tsim los ntawm polymerizing propylene. Cov txheej txheem no tshwm sim ntawm qhov kub thiab txias. Propylene molecules sib txuas ua ke los tsim cov saw ntev, tsim cov polypropylene. PP nthuav tawm lub zog siab, muaj kev cuam tshuam zoo heev, thiab kev kub siab, ua rau nws haum rau ntau daim ntawv thov, suav nrog ntim, khoom siv hauv tsev, khoom ua si, thiab cov khoom siv tsheb.

1.2. PVC yog dab tsi?

PVC sawv cev rau Polyvinyl Chloride, thermoplastic tsim los ntawm polymerization ntawm vinyl chloride (VCM). VCM yog cov roj uas tsim los ntawm ethylene thiab chlorine.PVCyog ib qho ntawm cov khoom siv ntau tshaj plaws hauv ntiaj teb, nrog rau kev tsim khoom txhua xyoo ntawm kwv yees li 40 lab tons.

1.3. Zoo sib xws ntawm Polypropylene vs PVC

Ob leeg Polypropylene (PP) thiab Polyvinyl Chloride (PVC) yog cov khoom siv thermoplastics thoob ntiaj teb. Ob hom yas no yog tsim los ntawm cov roj av thiab ua haujlwm hauv kev tsim khoom ntawm ntau yam khoom los ntawm kev tsim cov thermoplastic xws li kev txhaj tshuaj molding, extrusion, thiab thermoforming.

PP thiab PVC yog linear polymers, tsim los ntawm kev sib txuas monomer units ua ke los ntawm covalent bonds. Lawv yog insoluble nyob rau hauv dej thiab organic solvents.

Ob leeg PP thiab PVC muaj cov khoom siv hluav taws xob, thiab tshuaj lom neeg zoo heev, thiab tsis hnov ​​​​mob nrog cov kua qaub lossis cov hauv paus.

2. Polypropylene vs. PVC: Qhov twg zoo dua?

Polypropylene (PP) thiab PVC yog ob feem ntau siv cov ntaub ntawv thermoplastic nrog ntau daim ntawv thov. Ob leeg ntawm cov yas no tuaj nrog lawv tus kheej qhov zoo thiab qhov tsis zoo, thiab qhov twg yog qhov zoo dua nyob ntawm qhov xav tau tshwj xeeb ntawm daim ntawv thov.

2.1. PVC vs. Polypropylene hauv kev siv thiab kev ua haujlwm

Ob leegPolypropylenethiab PVC muaj cov ntawv thov sib txawv hauv ntau qhov kev lag luam. Feem ntau, PP thiab PVC tuaj yeem siv sib hloov. Cov ntawv thov siv Polypropylene suav nrog:

Ntim khoom noj thiab dej haus.

Cov khoom siv xws li cov khoom ua si thiab cov khoom siv hauv chav ua noj.

Automotive Cheebtsam zoo li lub cav npog thiab tso pa tawm, thiab lwm yam.

Daim ntawv thov siv PVC muaj xws li:

Cov kav dej thiab fittings rau kev tsim kho thiab dej systems.

Qhov rais thiab sab nrauv cladding hauv kev tsim kho kev lag luam.

Nov yog qee qhov kev siv uas tuaj yeem siv PP thiab PVC:

Hluav taws xob rwb thaiv tsev rau cov xov hlau.

Cov khoom siv textile (thaum extruded rau hauv fibers) xws li hnab tote, ntaub pua plag, ntaub pua plag, thiab khaub ncaws.

Ntim thiab ntim khoom kho mob, suav nrog cov vials thiab hnab tshuaj, IV hnab, Petri tais diav, thiab lwm yam.

2.2. Polypropylene vs PVC: recyclability thiab sustainability

Ob leeg polypropylene (PP) thiab PVC tuaj yeem siv dua tab sis los ntawm ntau txoj kev. Txawm li cas los xij, tsis yog PP lossis PVC yog ib puag ncig ruaj khov. PP tuaj yeem rov ua dua mus txog 100%, vim nws tuaj yeem ua rau hauv cov khoom me me, yaj, thiab rov siv ntau zaus rau ntau yam kev siv.

Ntawm qhov tod tes, PVC yog qhov nyuaj rau rov ua dua dua li PP. Vim muaj cov ntsiab lus chlorine siab hauv PVC, nrog rau lwm yam khoom siv phom sij, rov ua dua PVC yuav tsum muaj txheej txheem ntxiv.

Muaj ob txoj hauv kev rau kev rov ua dua PVC: mechanical recycling thiab feedstock recycling. Mechanical recycling, zoo ib yam li PP rov ua dua tshiab, suav nrog kev sib tsoo PVC rau hauv cov pellets me me thiab yaj cov khoom los tsim cov khoom tshiab.

PVC pellets raug cais los ntawm lwm cov yas vim yog cov khoom siv ntxiv. Feedstock recycling siv cov txheej txheem thermal thiab hydrolysis los hloov PVC rov qab rau hauv nws cov khoom qub.

2.3. PVC vs. Polypropylene - Nqi

Vim lawv cov nqi qis dua piv rau lwm cov ntaub ntawv thermoplastic, ob qho tib si polypropylene thiab PVC yog cov khoom siv thermoplastics thoob plaws ntiaj teb. PP yog tus nqi kwv yees li ntawm $ 1.20 toj ib kg, thaum PVC yog tus nqi nyob ib ncig ntawm $ 1.12 ib kilogram. Saj zawg zog PVC yuav yog me ntsis kim dua li tawv PVC vim cov txheej txheem thiab kev ua haujlwm yuav tsum tau ua kom nws hloov tau.

2.4. Lwm txoj hauv kev rau Polypropylene thiab PVC

Nylon thiab ABS yog ob qho khoom siv nrog cov khoom zoo ib yam li polypropylene thiab PVC. Nylon yog ib puag ncig tiv thaiv thiab muaj hluav taws xob zoo insulating zog, ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev siv hauv cables thiab cov khoom siv hluav taws xob.

Lub zog tensile thiab cuam tshuam ntawm ABS zoo ib yam li PP thiab PVC. Txawm hais tias ABS degrades thaum raug tshav ntuj ncaj qha, nws tseem siv los tsim ntau yam khoom zoo ib yam li cov khoom tsim los ntawm PP thiab PVC. Txawm li cas los xij, kev siv sab nraum zoov nrog ABS yuav tsum ua tib zoo tsim kom tsis txhob muaj qhov rhiab heev rau UV rays.
