Polypropylene vs Polyethylene
Polypropylene (PP) thiab polyethylene (PE) yog ob ntawm cov khoom siv thermoplastic feem ntau siv hauv ntiaj teb. Thaum lawv sib koom ntau qhov sib xws, lawv kuj muaj qhov sib txawv uas ua rau txhua yam khoom siv zoo dua rau qee yam kev siv. Tam sim no cia peb qhov sib txawv thiab qhov sib txawv ntawm polypropylene vs polyethylene
Polypropylene yog cov khoom siv ntau yam uas siv ntau yam kev lag luam, suav nrog tsheb, ntim khoom, thiab kev tsim kho. Nws muaj lub siab melting point, uas ua rau nws resistant rau tshav kub thiab tshuaj. Nws kuj yog ib qho khoom siv hnyav uas yooj yim rau kev ua thiab pwm. Polypropylene paub txog nws cov kav ntev thiab lub zog, uas ua rau nws zoo tagnrho rau cov ntawv thov uas yog qhov tseem ceeb.
Polyethylene, ntawm qhov tod tes, yog cov khoom siv tau yooj yim thiab softer uas yog siv rau ntau yam kev siv, xws li ntim khoom, polyethylene hmoov txheej, kev ua liaj ua teb, thiab kev kho mob. Nws yog ib qho khoom siv hnyav uas tiv taus cov dej noo thiab tshuaj lom neeg. Polyethylene kuj yog ib qho hluav taws xob zoo hluav taws xob, uas ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau hluav taws xob conductivity.
Thaum nws los txog rau lawv lub cev, polypropylene thiab polyethylene sib txawv ntawm ntau txoj hauv kev. Polypropylene yog nruj thiab nruj dua li polyethylene, uas ua rau nws yooj yim dua. Polyethylene yog softer thiab hloov tau ntau dua, uas ua rau nws tiv taus ntau dua thiab tsis tshua muaj kev tawg. Polyethylene kuj muaj cov ntsiab lus melting qis dua li polypropylene, uas ua rau nws yooj yim rau kev ua thiab pwm.
Hais txog tus nqi, polyethylene feem ntau tsis tshua kim tshaj polypropylene. Qhov no yog vim polyethylene yooj yim rau kev tsim thiab yuav tsum tau ua tsawg dua polypropylene. Txawm li cas los xij, tus nqi ntawm txhua yam khoom tuaj yeem sib txawv depending ntawm daim ntawv thov tshwj xeeb thiab kom muaj nuj nqis.
Thaum nws los txog rau ib puag ncig kev cuam tshuam, ob qho tib si polypropylene thiab polyethylene yog recyclable thiab tuaj yeem rov siv tau ntau yam kev siv. Txawm li cas los xij, polyethylene raug suav tias yog ib puag ncig zoo dua li polypropylene, vim nws yog tsim los ntawm cov qauv tshuaj yooj yim dua thiab yuav tsum muaj zog tsawg dua los tsim.
Hauv cov ntsiab lus, polypropylene thiab polyethylene yog ob ntawm cov khoom siv thermoplastic tshaj plaws hauv ntiaj teb. Thaum lawv sib koom ntau qhov sib xws, lawv kuj muaj qhov sib txawv uas ua rau txhua yam khoom siv zoo dua rau qee yam kev siv. Polypropylene paub txog nws lub zog thiab kav ntev, thaum polyethylene hloov tau yooj yim dua thiab tiv taus qhov cuam tshuam. Thaum xaiv ntawm ob cov ntaub ntawv, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov tshwj xeeb daim ntawv thov, lub cev muaj zog, tus nqi, thiab kev cuam tshuam ib puag ncig.
Polypropylene vs Polyethylene
Tam sim no peb tab tom nrhiav ib yam tshwj xeeb ntawm PP resin, tab sis peb tsis paub meej txog nws qhov tseeb muaj pes tsawg leeg thiab qauv. Peb yuav txaus siab rau nws yog tias koj tuaj yeem txais cov qauv ntawm peb thiab paub meej tias koj puas muab cov khoom tshwj xeeb no. Koj puas yog cov chaw tsim khoom ncaj qha, lossis koj puas ua lag luam? Peb nyiam koom ncaj qha nrog cov tuam txhab tsim khoom kom ruaj ntseg tus nqi sib tw thiab ua tau zoo raws li cov kev xav tau. Yog tias koj yog cov chaw tsim khoom, koj puas muab cov khoom pov thawj thaum xa khoom? Tsis tas li ntawd, koj puas tuaj yeem muab cov ntaub ntawv ntawm tus nqi muag, thiab FOB xa khoom ntawm qhov chaw nres nkoj hauv Suav teb puas tuaj yeem ua tau?
Peb tshwj xeeb xav tau PP resin haum rau yas dipping hauv kev tsim kho kev lag luam. Txawm hais tias yav dhau los peb tau siv cov qauv ntawm cov PP resin no, peb tsis muaj cov kev qhia tshwj xeeb thiab tau poob kev sib cuag nrog tus neeg muag khoom. Tam sim no, peb xav tau kev yuav khoom txhua xyoo ntawm 50 tons ntawm cov khoom no rau kev lag luam yas dipping. Nws yog ib qho tseem ceeb uas cov khoom muaj 100% muaj tseeb muaj pes tsawg leeg. Peb npaj siab yuav tau txais ib qho qauv me me rau kev sim, thiab yog tias nws ua raws li cov qauv qub, peb yuav mus rau qhov kev txiav txim txhua xyoo rau 50 tons.
