Pankhani yosankha zinthu zabwino kwambiri za polojekiti yanu, kusankha pakati pa mapepala a PP ndi mapepala a PPH kumakhala ndi gawo lalikulu. Ngakhale njira zonse ziwirizi zimapambana pamagwiritsidwe osiyanasiyana, kumvetsetsa mawonekedwe ndi mawonekedwe awo ndikofunikira. Mu positi iyi yabulogu, tikambirana za mawonekedwe, maubwino, ndi njira zabwino zogwiritsira ntchitoPP pepalas ndiChithunzi cha PPHs.
PolypropyleneMapepala (PP) amadziwika chifukwa cha mphamvu zawo zapadera, kulimba, komanso kusinthasintha. Mapepala opepuka awa amapereka kukana kwamankhwala kwabwino kwambiri, kuwapangitsa kukhala abwino kwazinthu zosiyanasiyana zamafakitale ndi zamalonda. Mapepala a PP amagwiritsidwa ntchito kwambiri m'mafakitale olongedza, magalimoto, ndi katundu wogula, makamaka chifukwa cha kuyamwa kwawo konyowa komanso kukana kukhudzidwa ndi kukwapula. Mapepalawa amadziwikanso kuti amakana ma asidi, maziko, ndi zosungunulira.
Mapepala a polypropylene homopolymer (PPH) amagawana zofanana zambiri ndi mapepala a PP, koma ali ndi mawonekedwe apadera.Chithunzi cha PPHs ali ndi mulingo wapamwamba wokhazikika komanso wamphamvu, zomwe zimawapangitsa kukhala abwino pantchito zofunidwa zomwe zimafunikira zida zamakina zowonjezera. Amawonetsa kukana kutentha kwambiri, kumapereka magwiridwe antchito mwapadera m'malo otentha kwambiri. Kuphatikiza apo, mapepala a PPH amakana kusweka ndikuwonetsa kukana kwamankhwala kwakanthawi yayitali.
Poyerekeza mapepala a PP ndi mapepala a PPH, zikuwonekeratu kuti katundu wawo ndi machitidwe awo amawasiyanitsa. Ngakhale zida zonsezi zimagawana zabwino zomwe zimafanana ndi kukana kwamankhwala komanso kulimba, mapepala a PPH amapereka mphamvu zamakina komanso kukana kutentha poyerekeza ndi mapepala a PP. Chifukwa chake, mapepala a PPH nthawi zambiri amakondedwa m'mapulogalamu omwe kulimba kowonjezera ndi kulimba ndikofunikira.
Pomaliza, kusankha pakatiPP pepalas ndi mapepala a PPH amadalira kumvetsetsa zofunikira za polojekiti yanu. Ganizirani zinthu monga kukana mankhwala, mphamvu zamakina, ndi kukana kutentha kuti mupange chisankho chodziwitsidwa.
