polypropylene yejira risiri rakarukwa,
PP Resin, PP resin yeBOPP indasitiri, PP resin yeInjection molding industry,

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

Vhiki rino polypropylene yakadzika yekutenga chinangwa yakadzikira, mafekitori ane mazororo, kuvakwa kwese kwakadzikira zvakanyanya.Pakazara, iyo yepamba polypropylene yakadzika indasitiri (inosanganisira epurasitiki kuruka, jekiseni kuumba, BOPP, PP risiri-yakarukwa jira) chiyero chekushanda chese chakadonha ne14.7% kusvika 36.2%.Mwero wekuruka kwepurasitiki wakadzikira ne9,5% kusvika 34%;Jekiseni kuumba mwero pasi 17% kusvika 32%;BOPP inotanga kudonha 2.8% kusvika 60.1%;Zvisina-kurukwa zvinotanga zvakadonha 29.8% kusvika 18.5%.

Kubva pakuona kwedivi rekudiwa, svondo rino bhizinesi rekuruka bhizinesi rekushanda rakaderera zvakanyanya kupfuura svondo rapfuura, richidzika ne13% gore negore.Pakupera kwegore, mabhizinesi mazhinji apinda muzororo, mamiriro ekurongeka emabhizinesi akadzikira zvakanyanya, mamwe mabhizinesi anoraira zvishoma nezvishoma, kufarira kwemabhizinesi kudzoreredza zvigadzirwa kwakadzikira, kunyanya kugaya zvigadzirwa zvakapedzwa, mamiriro ekutengesa emusika. kwaitonhora;Panyaya yeBOPP indasitiri, mazuva ekurongeka emabhizinesi emuenzaniso svondo rino ari 7.89% zvichienzaniswa nenguva yapfuura.Sezvo kudiwa kwese kweBOPP kusina kunaka semumakore apfuura, kudzika uye vatengesi vari pazororo pachine nguva, uye mamiriro ekutengeserana emusika ari kuwedzera kureruka sezvo Mutambo weChirimo unosvika.Mazhinji emabhizinesi e membrane akaisa maodha pamberi, uye mazhinji emabhizinesi e membrane ari kushanda zvakajairwa padanho razvino, nekutevera kushoma kwemaodha matsva.Indasitiri yekuumba jekiseni inotanga kuderera zvakanyanya, mafekitori ane mazororo, iyo indasitiri inotanga kuderera zviri pachena;Indasitiri yemachira isina-yakarukwa mukati mevhiki kuti itange kururamisa kwakakosha, vhiki ino yekurongeka mazuva kana ichienzaniswa nesvondo rapfuura -3.5 mazuva, mirairo yepasi yakaratidza kuderera.PP mabhizinesi asina kuruka machira apinda muzororo, mabhizinesi matsva ekutengeserana idiki kwazvo.Kazhinji, yakakanganiswa nezororo reMutambo weChirimo, kuvakwa kwese kuzasi kwakadonha zvakanyanya, zororo risati rasimudzirwa neramangwana, mashandiro emasheya akavandudzwa, achitsigira polypropylene musika muitiro wakasimba.

Mukufamba kwenguva, polypropylene kupa uye kudiwa kwakakosha mutambo uchiri pachena.Mushure mezororo, pane tarisiro yekuunganidza mumusika.Uye zvakare, muhurongwa hwehutsva hwekugadzira, Guangdong Petrochemical inotarisirwa kuburitsa zvinhu panguva yezororo, uye musika wekupa kudzvanywa kunowedzera zvakanyanya.Panyaya yekuda, hurongwa hwekutanga basa rezasi mushure mezororo ndiyo inonyanya kunetseka pamusika.Zvinokurudzirwa kuti vashandi vanyatsoteerera kune yakadzika rwizi rwekutanga basa.
