PP yog dab tsi? Cov ncauj lus kom ntxaws txog cov khoom thiab kev siv ntawm polypropylene (PP)
Thaum nws los txog rau cov ntaub ntawv yas, ib lo lus nug feem ntau yog dab tsi yog PP ua los ntawm PP, los yog polypropylene, yog ib qho thermoplastic polymer uas muaj ntau heev nyob rau hauv lub neej txhua hnub thiab kev lag luam. Hauv tsab xov xwm no, peb yuav txheeb xyuas kom meej txog cov tshuaj thiab lub cev ntawm cov khoom siv PP thiab nws cov kev siv ntau yam hauv ntau qhov chaw.
PP yog dab tsi?
PP (Polypropylene) Suav lub npe rau polypropylene, yog cov khoom siv hluavtaws tsim los ntawm polymerization ntawm propylene monomer. Nws belongs rau polyolefin pab pawg neeg ntawm plastics thiab yog ib qho ntawm feem ntau siv plastics nyob rau hauv lub ntiaj teb no. Cov ntaub ntawv polypropylene tau dhau los ua tus ncej tseem ceeb ntawm kev lag luam yas vim lawv cov kev ua tau zoo thiab cov nqi tsim khoom tsawg.
Cov qauv tshuaj thiab cov khoom ntawm PP
Los ntawm cov tshuaj lom neeg pom, cov qauv molecular ntawm PP yog qhov yooj yim thiab muaj cov pa roj carbon thiab hydrogen atoms.PP muaj cov qauv linear nrog ntau cov propylene units hauv cov saw hlau molecular, thiab cov qauv no muab cov tshuaj tiv thaiv zoo thiab ruaj khov.PP cov khoom tsis muaj ob daim ntawv cog lus, thiab yog li qhia tau hais tias muaj kev tiv thaiv siab rau oxidation, acid thiab alkali ib puag ncig. hluav taws xob Cov khoom siv tau zoo heev hluav taws xob rwb thaiv tsev thiab tsis tshua muaj noo noo nqus, ua rau nws dav siv nyob rau hauv hluav taws xob thiab hluav taws xob teb.
Physical Properties ntawm PP
Lub cev muaj zog ntawm polypropylene txiav txim siab nws siv nyob rau hauv ntau yam kev siv.PP muaj ib tug high degree ntawm crystallinity, uas ua rau nws heev nruj thiab muaj zog.PP muaj ib tug tsawg ntom (kwv yees li 0.90 mus rau 0.91 g / cm³), uas yog ib qho ntawm cov qis tshaj ntawm plastics, ua PP cov khoom kuj sib sib zog nqus.Qhov siab melting point ntawm PPs (170 ° C) yuav siv tau rau 106 ° C. tau deformed.PP muaj qhov kub siab melting point (160 txog 170 ° C), uas ua rau nws siv tau nyob rau hauv qhov kub siab dua yam tsis tau deformed. deformation. Cov khoom siv lub cev no ua rau PP zoo tagnrho rau kev ntim khoom, khoom siv hauv tsev thiab cov khoom siv tsheb.
Cov chaw siv rau cov ntaub ntawv PP
Vim nws cov khoom zoo heev, PP yog siv rau ntau yam kev siv. Hauv kev lag luam ntim khoom, PP feem ntau yog siv los ua cov hnab yas, ntim khoom noj thiab lub hau lub raj mis vim nws tsis muaj tshuaj lom, tsis muaj ntxhiab thiab khaws cov zaub mov tshiab rau lub sijhawm ntev. Hauv kev kho mob, PP yog siv los ua cov koob txhaj tshuaj thiab cov khoom siv pov tseg, uas yog cov nyiam rau lawv cov tshuaj tiv thaiv thiab kev ua kom tsis muaj menyuam zoo, thiab hauv kev lag luam tsheb, qhov twg nws yog siv los ua cov tha xim sab hauv thiab cov bumpers, nrog rau lwm yam, vim tias nws muaj kev cuam tshuam zoo heev thiab lub teeb yuag.
Environmentally Friendly thiab Sustainable
Nrog rau kev paub txog kev tiv thaiv ib puag ncig, cov khoom siv PP muaj nuj nqis rau nws cov khoom siv rov ua dua tshiab.PP cov khoom tuaj yeem rov ua dua thiab rov siv dua los ntawm cov khoom siv rov ua dua tshiab lossis cov tshuaj siv tshuaj rov ua dua tshiab, txo lub nra ntawm ib puag ncig.PP cov pa roj carbon tsawg thiab cov khoom degradable kuj ua rau nws muaj zog sib tw rau yav tom ntej eco-friendly cov ntaub ntawv.
Xaus
Cov lus nug ntawm dab tsi PP yog ua los ntawm tuaj yeem teb tau tag nrho los ntawm nws cov qauv tshuaj, lub cev lub cev, thiab ntau yam kev siv.PP yog ua lub luag haujlwm tseem ceeb hauv kev lag luam loj zuj zus raws li kev lag luam, ruaj khov, thiab ib puag ncig zoo. Yog tias koj xav tau tus nqi-zoo thiab ntau yam thaum xaiv cov khoom yas, PP yog qhov kev xaiv zoo tshaj plaws.
