Dab tsi yog qhov sib txawv ntawm pp thiab mfppp cov khoom lag luam?

Pp (polypropylene) yog ib qho khoom siv yas uas muaj cov cua sov tiv taus zoo, tshuaj lom neeg ua kom tsis taus thiab tsis ntom ntom ntom. MFPP (hloov polypropylene) yog hloov cov khoom polypropylene nrog lub zog muaj zog thiab muaj zog. Rau cov khoom siv ob yam no, cov kab lus no yuav muab cov kev qhia nrov tshaj tawm txog cov khoom siv raw, kev npaj, cov yam ntxwv, thiab cov ntawv thov.

1. Cov Khoom Siv Raw Khoom NtawmPp thiab mfppCov khoom siv raw ntawm PP tau npaj los ntawm polymerizing propylene hauv roj av. Propylene yog cov khoom petrochemical feem ntau tau los ntawm cov txheej txheem tawg hauv kev ua kom huv. Hloov polypropylene MFPP txhim kho nws txoj kev ua tau zoo los ntawm kev ntxiv cov hloov kho rau cov pp zoo tib yam. Cov qauv hloov kho no tuaj yeem ua ntxiv, sau rau cov tub luam lossis lwm cov qauv hloov kho uas hloov cov qauv polymer thiab muaj pes tsawg leeg los muab nws cov tshuaj zoo dua qub thiab tshuaj.

2. Npaj cov txheej txheem ntawm PP thiab MFPP qhov kev npaj ntawm PP yog ua tiav tau los ntawm polymerization cov tshuaj tiv thaiv. Propylene Monomer yog polymerized rau cov ntaub pua npab ntawm ib qho ntev los ntawm kev ua ntawm catalyst. Tus txheej txheem no tuaj yeem tshwm sim tsis tu ncua lossis sib quas ntus, ntawm qhov kub thiab txias. Kev npaj ntawm MFPP yuav tsum tau sib xyaw cov hloov kho thiab pp. Los ntawm cov sib tov yaj sib xyaw lossis kev daws teeb meem sib tov, cov hloov kho tau xeb yog covyees dispersed nyob rau hauv lub pp matrix, li txhim kho cov khoom ntawm pp.

3. Cov yam ntxwv ntawm PP thiab MFPP PP muaj cov cua sov tsis kam thiab tshuaj lom neeg ruaj khov. Nws yog aPob tshab yas nrog qee yam nyuaj thiab nruj. Txawm li cas los xij, lub zog thiab tawv ntawm cov pp zoo tib yam yog qhov tsawg, uas ua rau cov lus qhia ntawm cov ntaub ntawv hloov xws li MFPP. MFPP ntxiv qee cov hloov kho rau PP los ua MFPP muaj lub zog zoo dua, kev tiv taus thiab cuam tshuam tsis kam. Modifiers tseem tuaj yeem hloov cov thermal conductivity, hluav taws xob thiab huab cua tsis kam ntawm MFPP.

4. Daim ntawv thov ntawm PP thiab MFPP PP yog siv dav thiab siv tau thiab siv tau cov khoom siv hluav taws xob thiab lwm yam khoom hauv lub neej txhua hnub. Vim tias nws cov cua sov tsis kam thiab tshuaj tiv thaiv, pp tseem siv hauv cov kav dej, ntim, li qub thiab lwm yam khoom siv hauv kev lag luam tshuaj lom neeg. MFPP feem ntau siv hauv cov ntawv thov ua kom muaj zog thiab muaj zog, xws li cov khoom lag luam hluav taws xob, cov ntaub ntawv hauv tsev, thiab lwm yam.

Hauv kev xaus, PP thiab MFPP yog ob yamYas KhoomCov. PP muaj cov yam ntxwv ntawm cov cua sov tsis kam, kev siv tshuaj lom neeg tiv taus pp ntawm lub hauv paus no kom tau lub zog zoo dua, kev tiv taus zoo thiab cuam tshuam. Cov khoom no ua lub luag haujlwm tseem ceeb hauv cov ntawv thov sib txawv, nqa cov kev yooj yim rau peb lub neej thiab ntau yam kev muaj tsheb.
