Momwe mungasinthire index yosungunuka ya masterbatch yopanda nsalu?

Ambiri onyamula kwasanali nsalu masterbatchndi polypropylene (PP), yomwe imakhala ndi mphamvu yamafuta. Ngati mukufuna kukonza ndondomeko yosungunuka ya masterbatch yopanda nsalu, pali njira zitatu zoyesera. Pansipa, mkonzi wa Jisi adzakudziwitsani mwachidule.

Njira yosavuta yomwe sikutanthauza zowonjezera - kutenthedwa

Zimatanthawuza kuti panthawi yosakaniza kwambiri, kutentha kuyenera kukhala kwakukulu, kapena pawiri-screw kapena kusakaniza mkati, kutentha kuyenera kukhala kwakukulu. Pogwiritsa ntchito kuwonongeka kwa polypropylene, malo osungunuka amatha kukwezedwa ndi gawo, lomwe ndilosavuta komanso silifuna zowonjezera.

Gwiritsani ntchito zonyamulira zam'manja kwambiri ngati masterbatch

Ngakhale tilinso ndi zowonjezera zowonjezera zomwe zimayenera kupangidwa ndi nsalu zopanda nsalu za masterbatch kunyumba, sitikulangiza opanga nsalu za masterbatch osalukidwa kuti agwiritse ntchito sera yambiri kapena zowonjezera kuti zisungunuke. Chifukwa chapadera cha sanali nsalu nsalu masterbatch, ntchito sera ndi zina kuwonjezera Sungunulani index zambiri zimayambitsa ngozi kunsi kwa mtsinje. Chifukwa chake, sitikukulimbikitsani kugwiritsa ntchito zowonjezera kuti musinthe index yosungunuka ya masterbatch yopanda nsalu. Ndikwabwino kugwiritsa ntchito zonyamulira kuti muchepetse index yosungunuka. Kwa onyamula, mutha kusankha cholozera chapadera chosungunuka chapamwamba 100 kapena 150 melt index. Malo ena oyeretsera amatha kupanga polypropylene yokhala ndi index yosungunuka ya 100-150, yomwe ingagwiritsidwe ntchito ngati zonyamulira.

Onjezani peroxides kuti muwonjezere index yosungunuka

Kugwiritsa ntchito peroxide kuti muchepetse index yosungunuka ndi lupanga lakuthwa konsekonse. Peroxides ndiye zigawo zazikulu za cooling masterbatch yathu yomwe imagwiritsidwa ntchito kwambiri, kuphatikiza ma peroxides monga bis (2-ethylhexyl) phthalate, di tert butyl phthalate, ndi DCP. Kuonjezera masauzande angapo a peroxides kukhoza kuonjezera mtengo ndi pang'ono, zomwe zingathe kusintha kwambiri ndondomeko yosungunuka ya masterbatch yanu. Komabe, panthawi imodzimodziyo, idzasokoneza dongosolo lonse ndikukhudza makina ake pamlingo wina. Choncho, izi ziyenera kugwiritsidwa ntchito mosamala.

Mapeto

M'malo mwake, masterbatch yopanda nsalu nthawi zambiri safunikira kukhala ndi index yosungunuka kwambiri. Ngati mukupanga mankhwala okhala ndi ultra-high fluidity kapena ulusi wabwino kwambiri, muyenera kukhala ndi index yosungunuka kwambiri. Masterbatch wamba wosalukidwa sakhala ndi index yosungunuka kwambiri. Ngati mukufunadi kusintha ndondomeko yosungunula, monga kuonjezera chiwerengero cha melt index of non-woven fabric masterbatch kuchokera 20 mpaka 100, ndiye tsatirani njira zitatuzi.
