Ponena za kusankha zinthu zoyenera pa polojekiti yanu, kusankha pakati pa mapepala a PP ndi mapepala a PPH kumachita gawo lofunika kwambiri. Ngakhale kuti njira zonse ziwirizi zimachita bwino kwambiri pa ntchito zosiyanasiyana, kumvetsetsa makhalidwe awo apadera ndikofunikira. Mu positi iyi ya blog, tifufuza zinthu, maubwino, ndi njira zabwino zogwiritsira ntchito.Pepala la PPndiPepala la PPHs.
PolypropyleneMapepala a (PP) amadziwika ndi mphamvu zawo zapadera, kulimba, komanso kusinthasintha kwawo. Mapepala opepuka awa amapereka kukana mankhwala bwino kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri pamafakitale ndi mabizinesi osiyanasiyana. Mapepala a PP amagwiritsidwa ntchito kwambiri m'mafakitale opaka, magalimoto, ndi zinthu zogulira, makamaka chifukwa cha kusayamwa chinyezi komanso kukana kukhudzidwa ndi kukanda. Mapepala awa amadziwikanso chifukwa chokana asidi, maziko, ndi zosungunulira.
Mapepala a polypropylene homopolymer (PPH) ali ndi zofanana zambiri ndi mapepala a PP, koma ali ndi makhalidwe enaake apadera.Pepala la PPHMapepalawa ali ndi kulimba kwambiri komanso mphamvu zambiri, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito zinthu zovuta zomwe zimafuna mphamvu zowonjezera zamakina. Amakhala ndi kukana kutentha kwambiri, ndipo amagwira ntchito bwino kwambiri m'malo otentha kwambiri. Kuphatikiza apo, mapepala a PPH amalimbana ndi ming'alu ndipo amakhala ndi kukana kwa mankhwala kwa nthawi yayitali.
Poyerekeza mapepala a PP ndi mapepala a PPH, zimaonekeratu kuti makhalidwe awo ndi magwiridwe antchito awo zimawasiyanitsa. Ngakhale kuti zipangizo zonse ziwiri zimagawana makhalidwe ofanana monga kukana mankhwala ndi kulimba, mapepala a PPH amapereka mphamvu yabwino yamakina komanso kukana kutentha poyerekeza ndi mapepala a PP. Chifukwa chake, mapepala a PPH nthawi zambiri amakondedwa pamene ntchito zake zimakhala zolimba komanso zolimba.
Pomaliza, kusankha pakati paPepala la PPMapepala a s ndi PPH amadalira kumvetsetsa zofunikira zapadera za polojekiti yanu. Ganizirani zinthu monga kukana mankhwala, mphamvu ya makina, ndi kukana kutentha kuti mupange chisankho chodziwa bwino.
