Applications
(ningbo) Taiwan Formosa Plastics pp5090t inonyanya kushandiswa:
PP ndeye semi crystalline zvinhu.Iyo yakaoma kupfuura PE uye ine nzvimbo yakakwira yekunyungudika.Sezvo homopolymer mhando PP ine brittle zvakanyanya kana tembiricha iri pazasi 0 ℃, zvakawanda zvekutengesa zvePP zvinhu zvinongoitika copolymers ane 1-4% ethylene kana clamp rudzi copolymers ane ethylene yemukati.Iyo copolymer mhando PP zvinhu ine yakadzika yekupisa yekukanganisa tembiricha (100 ℃), yakaderera pachena, yakaderera gloss uye yakaderera kuomarara, asi ine simba rakasimba rekuita.
Kuyerera kweMFR yePP inotangira kubva ku1 kusvika ku40. PP ine MFR yakaderera ine zviri nani kukanganisa kupikisa asi kuderera kwesimba.Kune zvigadzirwa zvine MFR imwechete, kusimba kweiyo copolymer mhando yakakwirira kupfuura iyo yemhando yehomopolymer.Nekuda kwekristaro, iyo shrinkage rate yePP yakanyanya kukwirira, kazhinji 1.8-2.5%.Uye iyo inotungamira yakafanana ye shrinkage iri nani kupfuura iyo yePE-HD uye zvimwe zvinhu.Kuwedzera 30% yegirazi yekuwedzera inogona kuderedza shrinkage kusvika 0.7%.
Homopolymer mhando uye copolymer mhando PP zvinhu zvine yakanakisa mwando kunyudza kuramba, acid-base corrosion resistance uye dissolution kuramba.Nekudaro, haina kurwisa kune inonhuhwirira hydrocarbon (yakadai sebenzene) solvent uye chlorinated hydrocarbon (carbon tetrachloride) solvent.PP haina oxidation inopikisa pakupisa kwakanyanya sezvinoita PE.
Zvinoenderana nekuita kuri pamusoro, PP yakakodzera kune zvinotevera zvigadzirwa:
1. Jekiseni: mavharuvhu, zvishongedzo, kireti, mota, kuvharwa, midziyo yemagetsi, mabhodhoro emvura, maContainer echikafu, zvinhu zvemumba, matoyi, majekiseni asina kuzadzwa.
2. Extrusion: gobvu shizha, pepa, pombi, uswa, kusunga tepi, stationery sheet, BOPP firimu Sheet uye strip.
3. Blow molding: bhodhoro.
4. Thermoforming: tireyi, mbiya, jelly mukombe, mvura mukombe.
5. Shinda yakatsetseka: bhegi rakarukwa, bhegi remudziyo, kapeti.
