zvigadzirwa

PP resin yePP yekutarisa inotambanudza polypropylen,
Polypropylene resin kugadzira OPP firimu,

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

Application

Package

Iine anopfuura zana akasiyana akasiyana Polypropylene Firimu nderimwe remafirimu anonyanya kushandiswa pasi rose.Chishandiso chakajairika chepolypropylene chakafanana nepolypropylene (OPP).Iyi firimu ine yakanakisa hunyoro hunoratidza zvimiro izvo zvinoita kuti izvi zvive zvakanaka pakushandisa zvakajairwa ingi izvo zvinoburitsa yakajeka kwazvo yekudhinda mhedzisiro.Iko nhasi inotungamira inochinjika yekurongedza firimu yechipiri chete kune yakaderera density polyethylene muhuwandu.

(OPP) Yakagadzirirwa Polypropylene Firimu
Iyo thermoplastic polymer inoshandiswa mumhando dzakasiyana dzekushandisa kubva pakurongedza, kusvika kumakapeti.Iko kushandiswa kwekutanga kwefirimu reOPP kuri mukurongedzerwa kwechikafu nekuda kwesimba rakanaka, kujeka kwepamusoro, zvakakwana zvipingamupinyi zvivakwa uye mutengo wakaderera uchienzaniswa necellophane.Chinenge chiri munharaunda yese yehupenyu hwako hwezuva nezuva.Polypropylene inopikisa zvakanyanya kuneta.Saka hinge yemhando yepurasitiki inogona kuvhurwa nekuvharwa kanopfuura ka1000 pasina kuneta.Mazhinji flip-top packaging ane izvi.Iyo yekunyungudika ye polypropylene inowanikwa kuburikidza ne extrusion uye kuumba.Iyo yakajairika yekuumba nzira inoshandiswa ndeye jekiseni molding.Humwe hunyanzvi kuumba kuvhuvhuta uye jekiseni rinotambanudza kuvhuvhuta.Nekuve nekugona kugadzirisa mamwe magiredhi ane chaiwo mamorekuru zvimiro panguva yekugadzira inoita huwandu hukuru hwekupedzisira-kushandiswa kwekushandisa.Muenzaniso weizvi ungave kushandiswa kweantistatic additive kubatsira iyo polypropylene pamusoro kurwisa tsvina neguruva.
