Yintoni imathiriyeli yelaphu lezonyango elingalukwanga?

Ilaphu lelaphu lezonyango elingalukwangasisixhobo sonyango esineempawu ezibalaseleyo zomzimba kunye neekhemikhali, ezisetyenziswa kakhulu kwicandelo lezonyango kunye nempilo. Kwimveliso yeendwangu ezingalukiweyo kwiinjongo zonyango, ukukhetha izinto ezahlukeneyo kunokuhlangabezana neemfuno kunye neemfuno ezahlukeneyo. Eli nqaku liza kuzisa izinto ezisetyenziswa ngokuqhelekileyo zamalaphu amayeza angalukwanga kunye neetafile zawo zokuthelekisa, ukuze abafundi baziqonde ngcono iimpawu kunye nokusetyenziswa kweentlobo ezahlukeneyo.izixhobo zonyango ezingalukwanga ilaphu.

Kwimveliso yeilaphu elingalukwanga elisetyenziselwa unyango, izinto eziqhelekileyo ziquka i-polypropylene (PP), i-polyester (i-PET), i-polyphenyl ether sulfide (PES), i-polyethylene (PE), njl. Ezi zixhobo zineempawu ezahlukeneyo kunye neenzuzo kunye nokungonakali, kunye nezinto ezahlukeneyo zingakhethwa ngokweemfuno ezahlukeneyo.

Izinto ezisetyenziswa ngokuqhelekileyo zamalaphu angalukwanga zonyango

Iipolypropylene (PP)

I-Polypropylene yimathiriyeli enokumelana nobushushu obuphezulu, ukumelana nokunxiba, ukuxhathisa ukubola, kunye nezinye iimpawu, ezisetyenziswa ngokubanzi kwimveliso yelaphu zonyango ezingalukwanga. Ilaphu le-PP elingalukwanga linamandla abalaseleyo kunye nokuqina, ukuphefumla okulungileyo, kunye nokusebenza kakuhle komqobo, okunokuthi kuthintele ngokufanelekileyo ukungena kwe-microorganisms kunye nokungcola. Isetyenziswa kakhulu kwiimveliso zonyango kunye nezempilo ezifana neegawuni zotyando, izikhafu zotyando, kunye nemaski.

Ipolyester (PET)

I-Polyester yimathiriyeli enamandla okuqina agqwesileyo, ukunganyangeki, ukufunxa kakuhle kwamanzi kunye nokuphefumla, kwaye isetyenziswa kakhulu kwimveliso yamalaphu angalukwanga ezonyango. Ilaphu elingalukwanga le-PET linokuthamba okuhle kunye nokuthuthuzela, kwaye likulungele ukusetyenziswa kwiimpahla zonyango, amabhandeji kunye nezinye iimveliso.

I-Polyphenol ether sulfide (PES)

I-Polyphenol ether sulfide yimathiriyeli eneempawu ezifana nokumelana nobushushu obuphezulu, ukuxhathisa ukubola, kunye nokumelana nokunxiba, isetyenziswa ngokubanzi kwimveliso yelaphu zonyango ezingalukwanga. Ilaphu elingalukwanga elenziwe ngezinto ze-PES linamandla okuqina kunye nokuqina, ukuphefumla okuhle, kunye nokusebenza kakuhle kokungena manzi, okwenza ukuba ilungele ukusetyenziswa kwimpahla yokwahlula yonyango, iitawuli zotyando kunye nezinye iimveliso.

Polyethylene (PE):

I-Polyethylene yinto enokuguquguquka okulungileyo, ukuphefumla, ukumelana nokunxiba, kunye nezinye iimpawu, ezisetyenziswa ngokubanzi kwimveliso yezonyango ezingalukwanga. Ilaphu elingalukwanga elenziwe ngezinto ze-PE linokuthamba okulungileyo kunye nokuthuthuzela, ukuphefumla okulungileyo, kunye nokusebenza kakuhle kokungena kwamanzi. Ilungele ukusetyenziswa kwiimveliso zonyango kunye nezempilo ezifana neegawuni zotyando, izikhafu zotyando, kunye nemaski.

Itheyibhile yokuthelekisa ukukhethwa kwezinto zonyango ezingalukwanga ngelaphu
