Dab tsi yog qhov txawv ntawm tus tsiaj, PE, thiab PP yas?
Olyethylene (Tsiaj), Polyethylene (PE), thiab polypropylene (PP) yog peb feem ntau dav siv thermoplastic polymers thoob ntiaj teb. Qhov feem ntau paub plastics, lawv muaj nuj nqis rau lawv cov versatility, durability, thiab tus nqi- ua hauj lwm zoo. Txawm li cas los xij, lawv muaj cov cim txawv cov qauv, cov khoom, thiab cov ntawv thov.
Polyethylene (PE)
Polyethylene yog lub ntiaj teb cov yas feem ntau. Nws yog cov polymer ua los ntawm ethylene monomers thiab yog tus cwj pwm los ntawm nws kev yooj yim, yoog raws, thiab kev tshuaj lom neeg kuj tsis zoo. Muaj ob peb hom tseem ceeb:
HDPE (siab - ntom polyethylene):Paub txog nws lub zog siab -} {} qhov sib piv, nws tsis txaus ntseeg, thiab tiv taus tshuaj thiab noo noo. Nws yog siv rau mis nyuj jugs, xab npum tshuaj, cov piping, thiab khoom ua si.
LDPE (tsawg {- ntom polyethylene):Nta ib hom qauv molecular tsawg, ua rau nws yoog tau, pob tshab, thiab lub teeb yuag. Nws yog ib qho siv rau cov hnab yas, cov tuav yeeb yaj kiab, thiab nyem.
PE yog feem ntau suav tias muaj kev nyab xeeb rau kev sib ze rau khoom noj thiab tau rov ua dua tshiab.
Polypropylene (pp)
Polypropylene yog qhov nyuaj, txhav, thiab tshuaj lom {{}} tsis kam. Ua los ntawm Propylene Monomers, nws muaj qhov siab dua melting taw tes (nyob ib ncig ntawm 160 degree) tshaj PE, ua rau nws zoo tagnrho rau cov ntawv thov. Cov cuab yeej no tso cai rau nws siv tshuab ntxuav tais diav {}}} Cov thawv muaj kev nyab xeeb, microwaveaveArate, thiab cov yas kettles yas. Nws tseem yog filigue - tiv taus, lub ntsiab lus nws tuaj yeem siv rau kev nyob hauv hinges (piv txwv li, ntawm flip {{9 {} lub kaus mom sab saum toj). Nws cov vagatility txuas rau cov chaw kuaj tsheb, textiles (zoo li cov ntaub pua plag (zoo li cov ntaub pua taw rooj thiab thermal ris tsho hauv qab), thiab ntim nrawm. PP yog lub teeb yuag thiab muaj cov waxy saum npoo uas xav.
Polyethylene TereFthalate (Tsiaj lossis Pete)
Tus tsiaj yog muaj zog, txhav, thiab pob tshab yas ntawm tsev neeg polyester. Nws yog ib qho teeb meem zoo heev rau noo noo thiab roj (zoo li CO2), uas ua rau nws cov khoom siv dej haus rau cov roj carbon monoxide, thiab ntim zaub mov (zoo li txiv laum huab xeeb). Nws qhov tseeb thiab iav {{{- zoo li lub ntsej muag zoo rau cov khoom lag luam tseem ceeb rau cov neeg siv khoom. Tsis tas li ntawd, tus tsiaj yog rov ua dua tshiab thiab yog cov siv tau yas tshaj hauv lub ntiaj teb, feem ntau tig mus rau hauv lub hwj tshiab lossis polyester fiber ntau rau cov khaub ncaws thiab ntaub pua plag. Nws muaj qhov ua tau zoo thermal kuj tab sis tsis yog feem ntau siv rau kub - sau cov ntawv thov tsis muaj kev kho mob tshwj xeeb.
Qhov sib txawv qhov sib txawv summarized:
Cov qauv tshuaj lom neeg & keeb kwm:PE yog qhov yooj yim tshaj plaws, ua los ntawm ethylene. PP yog qhov zoo sib xws tab sis muaj cov pab pawg methyl uas txuas, muab nws ua kub kub siab dua. Tus tsiaj yog polyester, ua rau nws nyuaj dua thiab muab tau los ntawm roj av hydrocarbons.
Thaum tshav kub kub tiv:PP muaj qhov siab tshaj plaws melting point (~ 160 degree), ua raws cov ntawv crystallized), thiab tom qab ntawd PEstallized cov ntaub ntawv), thiab tom qab ntawd PE (LDPE ~ 105℃~ 120 degree).
Cov Khoom Siv Teeb Meem:Tsiaj yog qhov zoo tshaj plaws thaiv kev tawm tsam gases thiab aromas, tseem ceeb rau fizzy haus. PE thiab PP yog zoo dua noo noo teeb meem tab sis pub cov roj av kom dhau los ntawm kev yooj yim dua.
Clarity & rigidity:Tus tsiaj yog ib txwm meej thiab tsis yeem. PP tuaj yeem ua pob tshab tab sis feem ntau yog opaque thiab yog txhav heev. HDPE yog opaque thiab tsis yeem, thaum LDPE yog hloov tau thiab txhais tau.
Thawj cov ntawv thov:Tsiaj yog rau fwj thiab fibers. PE yog rau cov yeeb yaj kiab, hnab, thiab cov thawv tsis sib xws (HDPE). PP yog rau cua sov - Cov thawv tiv thaiv, cov khoom lag luam, thiab cov neeg siv khoom.
Hauv kev xaus, thaum tus tsiaj, PE, thiab PP yog txhua yam plastics, lawv cov qauv kev ua kom muaj ntau yam ntawm cov khoom siv sib txawv hauv cov khoom ntim, kev tsim khoom, thiab cov khoom siv cov khoom lag luam.
