Njira zowonjezera luso lapamwamba la polypropylene

Ndi kuchuluka ntchito kwapolypropylene zipangizom'magawo osiyanasiyana, zofunikira pa luso lawo lapamwamba zimakweranso. Komabe, kutsika kwapamwamba kwa polypropylene palokha kumapangitsa kuti pakhale malire pakugwiritsa ntchito kwake. Chifukwa chake, momwe mungasinthire luso lapamwamba la polypropylene lakhala malo opangira kafukufuku.

Njira zingapo zowonjezera luso lapamwamba la polypropylene

Wonjezerani roughness pamwamba

Powonjezera kuuma kwa pamwamba pa polypropylene, kuthekera kwake kwapamwamba kumatha kuwongolera. Mwachitsanzo, sandblasting kapena kujambula mankhwala angagwiritsidwe ntchito pamwamba pa polypropylene kuwonjezera mawonekedwe ake geometric motero kumapangitsanso pamwamba mphamvu yake. Pakadali pano, kuuma kwapamtunda kumatha kuonjezedwanso kudzera m'njira monga kukonza mtengo wa ma elekitironi ndi kuyika ma ion.

Kusintha pamwamba

Kusintha kwapamwamba ndi njira yodziwika bwino yopititsira patsogolo luso lapamwamba la polypropylene. Mwachitsanzo, kupaka wosanjikiza wosintha pamwamba pa polypropylene, kuthekera kwake kwapamwamba kumatha kuonjezedwa. Zosintha wamba zimaphatikizapo siloxanes, polyamides, ndi zina zotere. Zosinthazi zimatha kupanga chomangira champhamvu kwambiri chamankhwala pamtunda wa polypropylene, potero kumapangitsa luso lake lapamwamba.

Kusintha kwa mankhwala

Kusintha kwa Chemical ndi njira yabwino kwambiri yopititsira patsogolo luso lapamwamba la polypropylene. Polypropylene imatha kupangidwa ndi copolymerized kapena kumezanitsidwa ndi zinthu zina kuti isinthe mawonekedwe ake. Mwachitsanzo, polypropylene ikhoza kupangidwa ndi copolymerized kapena kumezanitsidwa ndi acrylic acid, co methylacrylic acid, ndi zina zotero kuti apeze ma polima okhala ndi zinthu zabwino pamwamba.

Ndi njira zosinthira ziti zomwe zingagwiritsidwe ntchito kuwonjezera magwiridwe antchito?

Polypropylene, yofupikitsidwa ngati PP, ndi imodzi mwa mapulasitiki asanu omwe amagwiritsidwa ntchito kwambiri tsiku ndi tsiku komanso mafakitale. Kusintha kwa PP ndi gawo lalikulu lomwe limaphatikizapo mayendedwe ndi njira zosiyanasiyana. Cholinga, makamaka, ndikulipira zofooka za PP palokha ndikukulitsa magawo ake ogwiritsira ntchito. Zotsatirazi ndi njira zodziwika bwino zosinthira polypropylene:

1. Kusintha kokwezeka:PP zinthundi yofewa ndipo ilibe chithandizo chokwanira. Mawotchi a polypropylene, monga mphamvu, kuuma, ndi kukana kuvala, amatha kupitilizidwa powonjezera magalasi fiber, carbon fiber, nanomaterials, ndi zina zotero.

2. Kudzaza kusinthidwa: PP imakhala ndi kuchuluka kwa shrinkage ndipo imakonda kusinthika pambuyo popanga jekeseni. Powonjezera zodzaza monga ma inorganic powders ndi mikanda yaying'ono yamagalasi, mawonekedwe a polypropylene amatha kuwongolera, monga kukulitsa matenthedwe matenthedwe, kuchepetsa ndalama, ndikuwongolera kukhazikika kwa mawonekedwe.

3. Kusintha kophatikizana: Kusakaniza polypropylene ndi ma polima ena kapena zowonjezera kuti zikhale bwino, monga kuwonjezereka kwamphamvu, kukana mankhwala, kukana kutentha, ndi zina zotero.

4. Zowonjezera zogwirira ntchito: PP ilibe kuchedwa kwa malawi ndipo imakhala ndi vuto la nyengo. Kuwonjezera zowonjezera ndi ntchito zinazake, monga antioxidants, UV absorbers, retardants malawi, etc., akhoza kusintha kukana kwa nyengo ndi kukana moto wa polypropylene.

Mapeto

Ponseponse, pali njira zingapo zowonjezera luso lapamwamba la polypropylene. Njira zoyenera ziyenera kusankhidwa malinga ndi zochitika zosiyanasiyana zogwiritsira ntchito. Njirazi zimatha kupititsa patsogolo luso lapamwamba la zida za polypropylene, potero zimakulitsa magwiridwe antchito osiyanasiyana.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
