Cov txheej txheem los txhim kho lub peev xwm saum npoo ntawm polypropylene

Nrog rau daim ntawv thov ncecov ntaub ntawv polypropylenenyob rau hauv ntau qhov chaw, qhov yuav tsum tau rau lawv cov peev txheej saum npoo kuj nce siab thiab siab dua. Txawm li cas los xij, qhov muaj peev xwm ntawm qhov chaw qis ntawm polypropylene nws tus kheej ua rau qee qhov kev txwv ntawm nws daim ntawv thov. Yog li ntawd, yuav ua li cas txhawm rau txhim kho qhov muaj peev xwm ntawm polypropylene tau dhau los ua qhov kev tshawb fawb hotspot.

Muaj ntau txoj hauv kev los txhim kho lub peev xwm saum npoo ntawm polypropylene

Ua kom nto roughness

Los ntawm kev ua kom roughness ntawm polypropylene nto, nws lub peev xwm nto tuaj yeem txhim kho. Piv txwv li, sandblasting lossis kos duab kho tuaj yeem siv rau saum npoo ntawm polypropylene kom nws cov qauv geometric thiab yog li txhim kho nws lub peev xwm ntog. Meanwhile, deg roughness kuj yuav nce los ntawm txoj kev xws li electron beam processing thiab ion implantation.

Kev hloov kho saum npoo

Kev hloov kho deg yog ib txoj hauv kev los txhim kho qhov muaj peev xwm ntawm polypropylene. Piv txwv li, los ntawm txheej txheej ntawm kev hloov kho ntawm polypropylene, nws lub peev xwm saum npoo tuaj yeem nce ntxiv. Cov kev hloov pauv feem ntau suav nrog siloxanes, polyamides, thiab lwm yam. Cov kev hloov kho no tuaj yeem tsim cov tshuaj lom neeg muaj zog rau ntawm qhov chaw ntawm polypropylene, yog li txhim kho nws lub peev xwm ntog.

Kev hloov kho tshuaj

Kev hloov kho tshuaj yog ib txoj hauv kev zoo los txhim kho qhov muaj peev xwm ntawm polypropylene. Polypropylene tuaj yeem ua copolymerized lossis grafted nrog lwm yam tshuaj los hloov nws cov khoom nto. Piv txwv li, polypropylene tuaj yeem ua copolymerized lossis grafted nrog acrylic acid, co methylacrylic acid, thiab lwm yam kom tau cov polymers nrog cov khoom zoo.

Cov kev hloov pauv dab tsi tuaj yeem siv los ua kom muaj kev ua tau zoo?

Polypropylene, abbreviated li PP, yog ib qho ntawm tsib universal plastics siv dav hauv ob qho tib si niaj hnub thiab cov khoom lag luam. Kev hloov kho PP yog qhov dav dav uas muaj ntau yam kev qhia thiab kev sib txawv. Lub hom phiaj, feem ntau, yog los them rau qhov tsis txaus ntawm PP nws tus kheej thiab nthuav dav nws daim ntawv thov. Cov hauv qab no yog cov lus qhia rau kev hloov kho polypropylene:

1. Kev hloov kho kom zoo:PP khoomNws kuj yog mos thiab tsis muaj kev txhawb nqa txaus. Cov khoom siv ntawm polypropylene, xws li lub zog, nruj, thiab hnav tsis kam, tuaj yeem txhim kho los ntawm kev ntxiv iav fiber ntau, carbon fiber, nanomaterials, thiab lwm yam.

2. Filling modification: PP muaj tus nqi siab shrinkage thiab nws nquag deformation tom qab txhaj tshuaj molding. Los ntawm kev ntxiv cov fillers xws li inorganic hmoov thiab micro iav hlaws, cov yam ntxwv ntawm polypropylene tuaj yeem txhim kho, xws li nce thermal conductivity, txo cov nqi, thiab txhim kho qhov ruaj khov.

3. Kev hloov kho: Sib xyaw polypropylene nrog rau lwm cov polymers lossis cov khoom siv ntxiv los txhim kho nws cov khoom, xws li nce toughness, tshuaj tiv thaiv, kub tsis kam, thiab lwm yam.

4. Cov khoom siv ntxiv: PP tsis muaj nplaim hluav taws thiab muaj huab cua tsis zoo. Ntxiv cov khoom ntxiv nrog cov haujlwm tshwj xeeb, xws li tshuaj tua kab mob, UV absorbers, nplaim hluav taws, thiab lwm yam, tuaj yeem txhim kho huab cua tiv thaiv thiab hluav taws kub ntawm polypropylene.

Xaus

Zuag qhia tag nrho, muaj ntau txoj hauv kev los txhim kho lub peev xwm saum npoo ntawm polypropylene. Txoj kev tsim nyog yuav tsum raug xaiv raws li qhov sib txawv ntawm daim ntawv thov scenarios. Cov txheej txheem no tuaj yeem txhim kho qhov muaj peev xwm ntawm cov khoom siv polypropylene, yog li txhim kho lawv cov kev ua tau zoo hauv ntau daim ntawv thov.

Dongguan Liansheng Nonwoven Technology Co., Ltd.tau tsim nyob rau hauv lub Tsib Hlis 2020. Nws yog ib tug loj-scale non-woven npuag ntau lawm enterprise integrating kev tshawb fawb thiab kev loj hlob, ntau lawm, thiab muag khoom.
