Technical background

polypropylene resin nekuti ine yakanaka kuomarara uye kupisa kupisa, uye mushure mekushandurwa kunoreva kupfuma, nekuti izvi zvishoma nezvishoma zvinotsiva mamwe einjiniya mapurasitiki, anoshandiswa zvakanyanya mumotokari, midziyo yemagetsi uye imba nemimwe minda.

Kunyanya pa copolymerization polypropylene resin, kuburikidza nekufambira mberi kwekugadzira uye catalyst tekinoroji, inopa zvigadzirwa zvakanyanya kunaka mashandiro akazara. liquidity, zvakare haikwanise kuzara zvakakwana mune dzimwe nzvimbo dzekudiwa, saka zvakare inoda pahwaro hweiyo iripo brand impact copolymer polypropylene mushure mekugadziridzwa, kureva kuburikidza nekuwedzera nucleating agent elastomer inorganic filler kuti uwane zvinhu zvakaita sekusimba kwakanyanya.

Iko kuomarara kwepolypropylene zvinhu zvine kuomarara kwakanyanya uye yakakwira fluidity inowanzo vandudzwa nekuwedzera nucleating agent kana inorganic filler.Nekuwedzerwa kweinorganic filler senge calcium carbonate, talcum poda, mica, diatomite, nezvimwewo, kukotama kwepolypropylene resin Iyo inoshanduka simba uye flexural elastic modulus inowedzera zvishoma nezvishoma, asi panguva imwe chete, kurebesa uye kukanganiswa kwesimba repolypropylene kunowedzera. kuderedzwa, uye ruvara uye shrinkage yezvigadzirwa zve polypropylene zvichakanganiswa.Uyezve, kuwedzerwa kwenhamba yakakura ye inorganic fillers inovandudza kuwanda kwezvinhu, kudzora huremu hwezvigadzirwa, kunyanya mumunda wekushandisa mota.

Mumakore achangopfuura, kushandiswa kweiyo nucleating agent mu polypropylene kwakawedzera zvishoma nezvishoma.Mazhinji petrochemical zvirimwa anowedzera nucleating agent mune granulation process yekugadzira polypropylene resin.Kuwedzerwa kweiyo nucleating agent hakungove nekukanganisa kwemuvara wepolypropylene, asiwo kunogona kuvandudza kupisa kwekudzivirira uye kupenya kwepolypropylene resin.5%, kunyangwe huwandu hwekuwedzera huri hudiki, asi nekuda kwemutengo weiyo nucleating agent inodhura (maererano nemhando yechigadzirwa uye hunyanzvi nhanho, mutengo unowanzo mumakumi ezviuru kusvika mazana mashanu ezviuru), uchawedzera mutengo we polypropylene resin matani emazana akati wandei yuan.

Iyo polypropylene kuumbwa inogadzirwa kubva kune anotevera emhando zvigadzirwa nehuremu:

polypropylene resin100;

Heat stabilizer 0.05 ~ 2;

Stearate simbi munyu 0.02 ~ 0.5;

Inorganic filler 0.05 ~ 3;

Organic nucleating agent 0.01 ~ 0.2.

Polypropylene resin inoumbwa nekushandisa polypropylene resin, thermal stabilizer, stearic acid, metal salt, inorganic filler uye shoma shoma ye nucleating agent yakasanganiswa granulation kugadzirira, kusimba kwakanyanya, kupisa kwakanyanya uye kudhura kwakaderera, tekinoroji yekugadzirira iri nyore, iyo polypropylene resin. composite inogona kushandiswa mumotokari, midziyo yemumba uye yemumba nemimwe minda.
