zvigadzirwa

Ndezvipi zvigadzirwa zvinogadzirwa kubva kuPP?,
PP yeCaps uye Kuvharwa, PP resin yeArtificial uswa, PP resin yeChikafu Packaging,

Polypropylene is a synthetic resin yakagadzirwa nepolymerization yepropylene (CH3—CH = CH2) ine H2 seye molecular weight modifier.Kune matatu stereomers ePP - isotactic, atactic uye syndiotactic.PP haina mapoka epolar uye ine yakanakisa magetsi ekudzivirira zvivakwa.Kunyura kwayo mvura kuri pasi pe 0.01%.PP ndeye semi-crystalline polymer ine yakanaka kugadzikana kwemakemikari.Iyo yakagadzikana kune akawanda makemikari kunze kweakasimba oxidizers.Inorganic acid, alkali uye munyu mhinduro dzinenge dzisina kukuvadza paPP.PP ine yakanaka yekudzivirira kupisa uye yakaderera density.Kunyungudika kwayo kuri kutenderera 165 ℃.Iyo ine yakakwira tensile simba uye kuomarara kwepasi uye yakanaka kwezvakatipoteredza kusagadzikana crack resistance.Inogona kumira 120 ℃ nguva dzose.

Sinopec ndiyo yakakura kwazvo PP inogadzira muChina, Yayo PP huwandu hwakaverengera makumi mana neshanu muzana ehuwandu hwenyika.Iyo kambani parizvino ine 29 PP zvidyarwa nekuenderera mberi (kusanganisira izvo zviri kuvakwa).Tekinoroji dzinoshandiswa nezvikamu izvi dzinosanganisira Mitsui Chemical's HYPOL process, Amoco's gas phase process, Basell's Spheripol uye Spherizone process uye Novolen's gas phase process.Iine simba rayo rekutsvagisa sainzi, Sinopec yakazvimiririra yakagadzira yechipiri-chizvarwa loopprocess yekugadzirwa kwePP.

PP Zvimiro

1.Kuwanda kwehukama kuduku, chete 0.89-0.91, iyo imwe yemhando dzakareruka mumapurasitiki.

2.good mechanical properties, kunze kwekukanganisa kupikisa, mamwe ma mechanical properties ari nani pane polyethylene, molding processing performance yakanaka.

3.Iyo ine kupisa kwakanyanya uye kushandiswa kwekushisa kunopfuurira kunogona kusvika 110-120 °C.

4.good chemical properties, inenge isina kunwa mvura, uye haiiti nemakemikari akawanda.

5.the texture yakachena, kwete-chepfu.

6.electrical insulation yakanaka.

Inowanzo shandiswa chirevo chePP giredhi
