1, ceev
PP yog qhov tsawg tshaj plaws ntawm tag nrho cov hluavtaws resins, tsuas yog 0.90 ~ 0.91g / cm3, uas yog li 60% ntawm PVC ceev. Qhov no txhais tau hais tias ntau dua cov khoom ntawm tib lub ntim tau tsim nrog tib qhov hnyav ntawm cov ntaub ntawv raw.
2, khoom kho tshuab
Lub zog tensile thiab rigidity ntawm PP yog tus zoo, tab sis feem zog lub zog yog pluag, tshwj xeeb tshaj yog nyob rau hauv qis kub. Tsis tas li, yog tias muaj kev cob qhia lossis kev nyuab siab thaum lub sij hawm sau hauv tsab xov xwm, qhov ua tau zoo kuj yog txo qis. Txawm hais tias qhov muaj zog tsis zoo, nws cov khoom siv dag zog yuav sib tw nrog ntau dua nqi hluav taws xob tshuab hauv ntau qhov chaw tom qab hloov kho los yog kev txhawb zog.
3, tawv hardness
Qhov hardness ntawm cov tawv nqaij ntawm PP yog tsawg hauv tsib qho cov hom phiaj, tsuas yog zoo dua PE. Thaum lub crystallinity siab zog, qhov nyuaj yog qhov tseem ceeb ntxiv, tab sis tseem tsis zoo li PVC, PS, ABS, thiab cov zoo li.
4, thermal thaj chaw
Ntawm tsib lub ntsiab lus dav hlau, qhov kub kub ntawm PP yog qhov zoo tshaj plaws. PP yas khoom ua haujlwm ntawm 100 ° C ntev, thiab thaum tsis muaj quab yuam sab nraud, cov khoom PP yuav tsis deformed thaum heated rau 150 ° C. Tom qab siv ib tug nucleating agent los txhim kho lub xeev crystalline PP , lub tshav kub tuaj yeem ua ntxiv tau zoo dua qub, thiab nws tuaj yeem siv tau los ua lub nkoj kom sov hauv lub qhov cub microwave.
5, kev ntxhov siab ua haujlwm tsis zoo
Kev nyuab siab tseem tshuav hauv molded khoom, los yog cov khoom ua haujlwm nyob hauv kev nyuab siab tas mus li ntev, uas yuav ua rau kev tawg kev ntxhov siab. Organic solvents thiab surfactants yuav ua tau kom txhawb kev nyuab siab. Yog li, txoj kev ntsuam xyuas kev nyuab siab yog ua tiav thaum muaj ib tug surfactant. Ib tus kws pabcuam uas nquag siv yog ib qho alkyl aryl polyethylene glycol. Cov kev kuaj pom tau hais tias PP muaj qhov tsis zoo rau kev nyuab siab thaum tawg ntho hauv surfactant, thiab muaj cov tshuaj tiv thaiv zoo hauv cov huab cua, thiab me dua lub pob ntws khiav ntawm PP (qhov loj dua lub cev ua rau lub cev loj), qhov muaj zog ntawm txoj kev nyuab siab.
