Polypropylene yog dab tsi?

 

Polypropylene (PP)yog ib qho thermoplastic polymer uas tau siv dav hauv ntau yam kev siv vim nws muaj ntau yam, ua haujlwm ntev, thiab siv tau zoo. Nws yog ib qho ntawm feem ntau tsim cov yas thoob ntiaj teb thiab paub txog nws ntau yam khoom thiab kev siv. Ntawm no yog cov ntsiab lus ntawm polypropylene:

 

Chemical Structure thiab Properties

Chemical Structure

Polypropylene yog ib qho polymer ua los ntawm monomer propylene, uas yog hydrocarbon (C3H6). Cov txheej txheem polymerization suav nrog qhov sib ntxiv ntawm propylene molecules los ua cov saw ntev, ua rau cov khoom siv nrog cov qauv tshuaj rov ua dua. Cov tshuaj formula rau polypropylene yog (C3H6)n, qhov twg 'n' sawv cev rau tus naj npawb ntawm rov ua dua units.

Physical thiab Chemical Properties

Lub teeb yuag: Polypropylene muaj qhov ntom ntom, ua rau nws sib zog dua li ntau lwm yam yas.

Durability: Nws yog resistant rau qaug zog, txhais tau tias nws muaj peev xwm tiv taus rov khoov thiab flexing yam tsis tau tawg.

Chemical Resistance: Polypropylene tiv taus ntau yam tshuaj, suav nrog acids, bases, thiab cov kuab tshuaj.

Thermal Resistance: Nws muaj qhov siab melting point (nyob ib ncig ntawm 160 degree lossis 320 degree F), uas ua rau nws haum rau cov ntawv thov uas yuav tsum tau ua kom sov.

Moisture Resistance: Polypropylene tsis nqus dej, ua rau nws zoo tagnrho rau siv hauv qhov chaw ntub dej lossis ntub dej.

Hluav taws xob rwb thaiv tsev: Nws muaj cov khoom siv hluav taws xob zoo, ua rau nws muaj txiaj ntsig zoo hauv kev siv hluav taws xob.

 

Hom Polypropylene

Homopolymer Polypropylene

Hom no yog tsim los ntawm propylene monomers nkaus xwb thiab yog tus cwj pwm los ntawm lub zog-rau-hnyav piv, zoo tshuaj tsis haum, thiab siab thermal kuj. Nws yog dav siv nyob rau hauv ntim, textiles, thiab automotive qhov chaw.

Copolymer Polypropylene

Muaj ob lub ntsiab ntawm copolymer polypropylene:

Random Copolymer:Ua los ntawm polymerizing ethylene thiab propylene ua ke. Nws muaj qhov pom tseeb thiab yooj yim dua, ua rau nws haum rau cov ntawv thov xws li ntim khoom thiab cov khoom siv kho mob.

Block Copolymer:Muaj cov ethylene loj dua, muab kev txhim kho kev cuam tshuam. Hom no feem ntau siv rau hauv kev lag luam xws li cov kav dej thiab cov khoom siv tsheb.

 

Flammability ntawm Polypropylene

 

Hauv nws daim ntawv ntshiab, polypropylene tsis yog nplaim taws. Thaum raug nplaim taws, nws ignites yooj yim thiab txuas ntxiv hlawv txawm tias tom qab qhov hluav taws xob raug tshem tawm. Qhov kev coj cwj pwm no yog vim nws cov qauv hydrocarbon-based, uas muab cov roj txaus rau combustion. Cov txheej txheem hlawv ua kom muaj cua sov ntau thiab tuaj yeem tso cov pa phem xws li carbon monoxide thiab acrolein, uas ua rau muaj kev phom sij rau kev noj qab haus huv ntxiv hauv cov xwm txheej hluav taws kub.

Qhov flammability ntawm polypropylene yog ib qho kev txhawj xeeb tseem ceeb hauv cov ntawv thov uas qhov kev nyab xeeb hluav taws yog qhov tseem ceeb, xws li hauv cov khoom siv hauv tsev, cov khoom siv hluav taws xob, thiab kev thauj mus los hauv pej xeem. Txhawm rau daws qhov teeb meem no, cov kws tshawb fawb thiab cov chaw tsim khoom tau tsim ntau lub tswv yim los txhim kho cov nplaim hluav taws xob ntawm polypropylene.

 

Txhim kho nplaim taws retardancy hauv Polypropylene

 

Muaj ntau txoj hauv kev los txhim kho cov nplaim hluav taws xob ntawm polypropylene, feem ntau yog siv cov nplaim hluav taws xob ntxiv. Cov additives no tuaj yeem muab tso rau hauv cov polymer matrix thaum lub sijhawm tsim khoom los hloov nws cov yam ntxwv flammability. Qee qhov feem ntau siv hluav taws kub retardant additives rau polypropylene muaj xws li:

 

Halogenated nplaim retardants:

Halogenated tebchaw, xws li brominated thiab chlorinated nplaim retardants, muaj txiaj ntsig zoo hauv kev txo cov nplaim taws ntawm polypropylene. Lawv ua hauj lwm los ntawm kev tso tawm halogen radicals thaum lub sij hawm combustion, uas cuam tshuam cov tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv cov nplaim taws, yog li slows down lub burning txheej txheem. Txawm li cas los xij, kev siv cov nplaim hluav taws xob halogenated tau poob qis vim kev txhawj xeeb ntawm ib puag ncig thiab kev noj qab haus huv cuam tshuam nrog kev tso tawm cov pa roj carbon monoxide thiab cov pa phem tsis tu ncua.

 

Phosphorus-Based Flame Retardants:

Phosphorus-based compounds, suav nrog liab phosphorus thiab organophosphates, yog cov kev xaiv nrov rau cov nplaim hluav taws halogenated. Cov tebchaw no txhawb kev tsim cov char nyob rau saum npoo ntawm cov polymer, tsim kom muaj kev tiv thaiv kev tiv thaiv uas ua rau qeeb cua sov thiab huab cua hloov thaum lub sij hawm combustion. Phosphorus-raws li nplaim retardants feem ntau suav hais tias tsis tshua muaj tshuaj lom thiab ntau tus phooj ywg ib puag ncig dua li lawv cov halogenated counterparts.

 

Mineral Fillers:

Inorganic fillers xws li txhuas hydroxide, magnesium hydroxide, thiab antimony trioxide tuaj yeem txhim kho cov nplaim hluav taws xob ntawm polypropylene los ntawm diluting cov polymer thiab txhawb kev tsim cov txheej txheem ruaj khov. Cov additives decompose endothermically, absorbing tshav kub thiab tso dej los yog lwm yam uas tsis yog-flammable gases, uas yuav pab kom txias cov khoom thiab txo nws cov flammability.

 

Intumescent Systems:

Intumescent nplaim retardants yog tsim los o thiab tsim ib txheej insulating char txheej thaum raug tshav kub. Cov tshuab no feem ntau muaj cov pa roj carbon monoxide, cov kua qaub, thiab cov tshuab tshuab. Thaum rhuab, cov kua qaub los txhawb lub charring ntawm cov pa roj carbon monoxide, thaum lub tshuab tshuab ua cov pa roj uas ua rau cov khoom nthuav dav thiab tsim ib qho kev tiv thaiv. Intumescent systems muaj txiaj ntsig zoo hauv kev muab cov nplaim hluav taws xob tsis muaj qhov cuam tshuam rau cov khoom siv hluav taws xob ntawm polypropylene.

 

Kev siv cov nplaim hluav taws kub nyhiab polypropylene

 

Flame retardant polypropylene pom cov ntawv thov hauv ntau qhov kev lag luam uas muaj kev nyab xeeb hluav taws yog qhov kev txhawj xeeb tseem ceeb. Qee cov ntawv thov tseem ceeb suav nrog:

 

Kev tsim kho:
