Global - Premier Polyethylene: Iyo Polymer Inoshandiswa Zvakasiyana-siyana Yekushandisa Kwakasiyana-siyana
Minda mikuru yekushandisa
Polyethylene inozivikanwa nekudzivirira kwayo makemikari zvakanyanya. Inodzivirira zvakanyanya makemikari akasiyana-siyana, anosanganisira acids, bases, uye solvents. Hunhu uhwu hunoita kuti ive chinhu chakanakira kushandiswa mumaindasitiri emakemikari nemishonga, uko inoshandiswa kugadzira midziyo yekuchengetera, mapaipi, uye zvigadziko zvinogona kubata zvinhu zvinoparadza zvakachengeteka. Kusapinda kwayo makemikari kunoitawo kuti isasvibise zviri mukati mayo, zvichichengetedza kuchena uye kunaka kwezvinhu zvakachengetwa.
Muindasitiri yekurongedza, polyethylene inowanikwa kwose kwose. Kuwanda kwayo kushoma uye kuchinjika kwakanyanya kunoita kuti ive yakakwana yekugadzira mafirimu ekurongedza akareruka uye akasimba, mabhegi, uye midziyo. Inopa dziviriro inoshanda kubva kuhunyoro, okisijeni, nezvimwe zvinhu zvakatipoteredza, ichidzivirira zvigadzirwa zvakaputirwa kubva mukukuvadzwa nekuora. Ingave iri yekurongedza chikafu, uko inobatsira kuchengetedza hutsva uye mhando yezvinhu zvinoora, kana yekurongedza zvinhu zvevatengi, uko inopa mhinduro inokwezva uye inoshanda yekurongedza, polyethylene inoita basa rakakosha mukuona kuchengetedzeka uye kutengeswa kwezvigadzirwa.
Indasitiri yekuvaka inobatsirwawo zvikuru ne polyethylene. Inoshandiswa mukugadzira mapaipi emvura negesi. Mapaipi e polyethylene anozivikanwa nekusimba kwawo kwakanyanya, kugara kwenguva refu, uye kuramba kukweshwa nekukuvadzwa. Anogara kwenguva refu uye anoda kugadziriswa kushoma, zvichiita kuti ave sarudzo inodhura zvishoma pamapurojekiti ezvivakwa. Pamusoro pezvo, polyethylene inoshandiswa muzvinhu zvinodzivirira kupisa, ichipa hunhu hwakanaka hwekudzivirira kupisa hunobatsira kuderedza kushandiswa kwesimba muzvivakwa.
Muindasitiri yemotokari, polyethylene inoshandiswa mumabasa akasiyana-siyana. Inoshandiswa kugadzira zvinhu zvemukati zvakaita semadhibhodhi, mapaneru emusuwo, uye zvifukidziro zvezvigaro nekuda kwekureruka kwayo, nyore kuumba uye hunhu hwakanaka hwekunaka. Inoshandiswawo muzvikamu zvekunze zvakaita semabumpers nemafender, uko kuramba kwayo kunobatsira kuvandudza kuchengetedzeka uye kugara kwenguva refu kwemotokari. Uyezve, polyethylene inoshandiswa mumatangi emafuta nemafuta, nekuda kwekusagona kwayo kupinda mumafuta uye kugadzikana kwemakemikari.

Muchidimbu
Polyethylene yedu yepasi rose - Premier inowanikwa mumhando dzakasiyana siyana kuti ienderane nezvinodiwa nemaindasitiri akasiyana-siyana. Ingave polyethylene ine density yakakura (HDPE) yekushandisa inoda simba rakawanda uye kuomarara, kana polyethylene ine density yakaderera (LDPE) yekushandisa inochinjika uye inotatamuka, tinopa mhando dzakasiyana dzezvigadzirwa. Batch yega yega inoedzwa zvakanyanya kuti ive nechokwadi chekuti ine hunhu hwakafanana, kusanganisira kuyedzwa kwehuwandu, melt index, tensile strength, uye elongation. Polyethylene yedu yakaputirwa muzvinhu zvakakodzera zvekurongedza kuti idzivirire panguva yekuchengetwa nekutakurwa. Ingave uri kambani yekurongedza muAsia, kambani yekuvaka muEurope, mugadziri wemotokari muNorth America, kana mugadziri wemakemikari muSouth America, Global - Premier Polyethylene yedu ndiyo polymer yakavimbika uye inoshanda zvakanyanya yaunoda kuti uwedzere kunaka uye mashandiro ezvigadzirwa zvako.
