Yas Polypropylene (PP)
* Polypropylene yog ib hom thermoplastic semi crystalline. Nws muaj kev tiv taus kev cuam tshuam siab, muaj zog mechanical zog, thiab tiv taus ntau yam organic solvents thiab acid-base corrosion.
* Kev tiv thaiv tshuaj lom neeg zoo heev. Muaj cov qib zaub mov zoo.
* Cov khoom yas PP lossis cov khoom seem uas haum rau koj
Polypropylene, luv ua PP, yog ib qho polymer ua los ntawm propylene los ntawm kev sib xyaw ua ke. Nws yog cov khoom dawb, zoo li quav ciab nrog lub ntsej muag pom tseeb, sib dua. Cov mis tshuaj (C3H6) n, qhov ceev 0.89 ~ 0.91g / cm3, yooj yim hlawv, melting point ntawm 164 ~ 170 ° C, softened ntawm 155 ° C lossis li ntawd, kev siv qhov kub ntawm -30 ~ 140 ° C.
Nws tiv taus kev xeb los ntawm cov kua qaub, alkali, ntsev kua thiab ntau yam organic solvents hauv qab 80 ℃, thiab tuaj yeem lwj hauv qhov kub siab thiab oxidation. Nws yog siv rau ntau yam kev siv, suav nrog kev ntim khoom rau cov neeg siv khoom, cov khoom yas rau kev lag luam tsheb thiab cov ntaub.
Koj tuaj yeem ua dab tsi nrog PP Yas?
Polypropylene yog cov khoom siv yas sib dua tshaj plaws hauv qhov ceev. Nws cov tsos yog cov hmoov tsis muaj xim thiab pob tshab, thiab ua cov yas qib zaub mov, nws siv dav hauv cov ntim khoom noj, xws li cov thawv Styrofoam, khob yas PP, thiab lwm yam. Polypropylene tuaj yeem muab faib ua tsib pawg tseem ceeb raws li nws cov ntawv thov tseem ceeb: PP txhaj tshuaj molding, PP kos duab, PP fiber, PP zaj duab xis, thiab PP yeeb nkab.
Cov hauv qab no yog qee cov ntawv thov rau Polypropylene (pp)
- Cov khoom siv kho mob

Cov yam ntxwv ntawm Polypropylene (PP)
Kev tiv thaiv tshuaj lom neeg: Cov hauv paus diluted thiab cov kua qaub tsis cuam tshuam nrog PP, uas ua rau nws yog lub thawv zoo tagnrho rau cov kua zoo li no (piv txwv li cov neeg ua haujlwm ntxuav, cov khoom siv kho mob thawj zaug, thiab lwm yam).
Kev ywj pheej thiab kev tawv: PP yog ywj pheej nyob rau hauv qee qhov kev hloov pauv thiab dhau los ua cov yas deformation thaum ntxov hauv cov txheej txheem deformation yam tsis muaj kev tawg, yog li nws feem ntau suav hais tias yog cov khoom siv "tawv".
Tsis qaug zog: PP tseem zoo li qub tom qab tig thiab khoov ntau zaus. Cov yam ntxwv no muaj txiaj ntsig zoo rau kev ua cov pob qhov rooj txav tau.
Rwb thaiv tsev: Cov khoom siv PP muaj hluav taws xob tsis kam siab thiab yog cov khoom siv rwb thaiv tsev.
Kev Sib Kis: Nws tuaj yeem ua rau hauv cov xim pob tshab, tab sis feem ntau yog ua rau hauv cov xim tsis pom tseeb nrog qee qib ntawm kev sib kis. Yog tias xav tau kev sib kis siab, yuav tsum xaiv acrylic lossis PC.
Cov khoom siv PP ua li cas?
Ib yam li lwm cov yas, Polypropylene (PP) pib ua ib feem "feem" (pawg sib zog dua) los ntawm kev sib xyaw cov roj hydrocarbon thiab sib xyaw nrog lwm cov catalysts los tsim cov yas los ntawm kev sib xyaw ua ke lossis polycondensation reactions.

Polypropylene (PP) - Cov txheej txheem tsim khoom:
Cov hmoov tau txais thaum kawg raug xa mus rau cov silos hmoov thiab tom qab ntawd hloov mus ua pellets uas suav nrog ntau yam ntawm
cov additives uas tau tawg zoo.
Kev siv cov yas polypropylene (PP) dua tshiab thiab kev tiv thaiv ib puag ncig
Thaum polypropylene rov ua dua tshiab, nws txo qhov kev siv cov peev txheej tsawg xws li roj thiab roj propane. Kwv yees li 8% ntawm lub ntiaj teb cov roj (kwv yees li 400 lab tons) yog siv rau hauv cov txheej txheem tsim cov yas ib txwm muaj, uas 4% yog siv ua "khoom noj khoom haus" thiab lwm 4% yog siv rau hauv kev tsim khoom. Yog tias cov yas tau tsim los ntawm cov yas rov ua dua tshiab, kev siv hluav taws xob kuj yuav raug txo los ntawm 88%. Yog li ntawd, kev siv cov yas polypropylene rov ua dua tshiab yog tus phooj ywg ib puag ncig!
