Cov ntaub ntawv raw, PPR yeeb nkab los ntawm copolymerization polypropylene cov ntaub ntawv ntau lawm thiab ua, PVC kav ua los ntawm PVC cov ntaub ntawv ntau lawm; Phab ntsa thickness, phab ntsa thickness, PPR nyias PVC raj phab ntsa; Cov nqi siab dua, tus nqi ntawm cov kav dej dav dav PPR; SIV, PPR yeeb nkab ua cov yeeb nkab dej, PVC yeeb nkab siv los ntws.
Qhov txawv ntawm qhov tshwj xeeb raws li hauv qab no:
1, cov ntaub ntawv sib txawv PPR yeeb nkab yog copolymerization polypropylene cov ntaub ntawv ntau lawm, thiab PVC yeeb nkab yog tsim los ntawm PVC cov ntaub ntawv ntau lawm, kev tsim cov khoom sib txawv, nws cov kev ua tau zoo tsis zoo ib yam. Cov xim thiab luster ntawm PPR yeeb nkab thiab PVC khoom. PPR yeeb nkab ntawm cov khoom siv polypropylene zoo li ci ntsa iab thiab cov yeeb nkab khoom toughness zoo dua. PVC yeeb nkab yog milky dawb, ntau nto luster, tab sis tsis hla ntu, cov khoom tsis muaj zog.
2, txawv phab ntsa thicknessPPR yeeb nkab yog muab faib ua plaub rau hauv tus nqi, nyob rau hauv tus nqi ntawm thiab phab ntsa thickness yog 2.3 hli thiab 3.5 hli feem. PVC yeeb nkab txoj kab uas hla 6 hli phab ntsa thickness ntawm 2.0 hli, txoj kab uas hla ntawm 8 ~ 10 hli phab ntsa thickness ntawm 2.5 hli. PPR zoo ib yam li txoj kab uas hla ntawm PVC raj, tab sis nws tsis yog tib lub phab ntsa thickness, PPR yeeb nkab phab ntsa thickness, nyias PVC yeeb nkab phab ntsa.
3, tus nqi sib txawv Vim tias cov khoom siv thiab phab ntsa tuab, cov nqi tsim khoom ntawm PPR yeeb nkab thiab PVC yeeb nkab thiab tus nqi kuj muaj qhov sib txawv. Feem ntau, tus nqi siab dua ntawm PPR yeeb nkab.4, qhov sib txawv ntawm cov khoom siv, PVC raj dua li kev noj qab haus huv thiab kev nyab xeeb ntawm PPR yeeb nkab, PPR yeeb nkab feem ntau yog xaiv los ntawm cov yeeb nkab dej pub rau hauv tsev, tuaj yeem siv rau cov dej txias thiab kub. cov yeeb nkab, PVC yeeb nkab feem ntau yog siv los ntws, tsuas yog cov yeeb nkab dej txias
