Xa kufikwa ekukhetheni izinto ezifanelekileyo kwiprojekthi yakho, ukhetho phakathi kwamaphepha e-PP kunye namaphepha e-PPH ludlala indima ebalulekileyo. Nangona zombini ezi ndlela zibalaseleyo kwizicelo ezahlukeneyo, ukuqonda iimpawu zazo ezizodwa kunye neempawu kubalulekile. Kule posi yebhlog, siza kujonga iimpawu, iingenelo, kunye neemeko ezilungileyo zokusetyenziswaIphepha le-PPkunyeIphepha le-PPHs.
I-PolypropyleneAmaphepha (PP) aziwa ngamandla awo angaqhelekanga, ukuqina kwawo, kunye nokuguquguquka kwawo. La maphepha alula anika ukumelana okuhle kweekhemikhali, nto leyo eyenza ukuba afaneleke kakhulu kwizicelo ezahlukeneyo zemizi-mveliso kunye nezorhwebo. Amaphepha e-PP asetyenziswa kakhulu kwimizi-mveliso yokupakisha, yeemoto, kunye neempahla zabathengi, ngenxa yokuba afunxwa lula ngumswakama kwaye ayamelana nempembelelo kunye nemikrwelo. La maphepha ayaziwa nangokumelana kwawo nee-asidi, iziseko, kunye nezinyibilikisi.
Amaphepha e-polypropylene homopolymer (PPH) afana kakhulu namaphepha e-PP, kodwa aneempawu ezithile ezikhethekileyo.Iphepha le-PPHZinomgangatho ophezulu wokuqina namandla, nto leyo eyenza ukuba zilungele ukusetyenziswa ngokungxamisekileyo ezifuna iipropati zoomatshini eziphuculweyo. Zibonisa ukumelana nobushushu okugqwesileyo, zibonelela ngokusebenza okugqwesileyo kwiindawo ezinobushushu obuphezulu. Ngaphezu koko, amaphepha e-PPH ayamelana nokuqhekeka kwaye abonisa ukumelana neekhemikhali okugqwesileyo ixesha elide.
Xa kuthelekiswa amaphepha e-PP kunye namaphepha e-PPH, kuyacaca ukuba iimpawu zawo kunye nezinto ezisebenza ngazo ziyahlula. Nangona zombini ezi zinto zineempawu ezifanayo ezifana nokumelana neekhemikhali kunye nokuqina, amaphepha e-PPH anika amandla angcono oomatshini kunye nokumelana nobushushu xa kuthelekiswa namaphepha e-PP. Ke ngoko, amaphepha e-PPH adla ngokukhethwa xa kusetyenziswa apho ukuqina kunye nokuqina okungakumbi kubalulekile.
Ukuqukumbela, ukukhetha phakathiIphepha le-PPAmaphepha e-s kunye ne-PPH axhomekeke ekuqondeni iimfuno ezizodwa zeprojekthi yakho. Cinga ngezinto ezinje ngokuxhathisa iikhemikhali, amandla oomatshini, kunye nokuxhathisa ubushushu ukuze wenze isigqibo esinolwazi.
