Menene pe?
PE, wanda aka sani da polyethylene (polyethylene), shine ɗayan kayan filastik da aka fi amfani da shi a duniya. Saboda kyakkyawan kayan jiki da kayan sunadarai, ana amfani da kayan pe cikin manyan masana'antu. Daga kwafar jaka zuwa pipping kayan, polyethylene kusan kusan ko'ina. A cikin wannan labarin, zamu bincika dalla-dalla game da pe ne, nau'ikan ta, kaddarorin da wuraren aikace-aikace.
1. Tsarin sunadarai da rarrabuwa na pe
PE wani m resin waje ne daga ethylene monomers ta hanyar amsawar polymerisisation. Ya danganta da yanayin matsa lamba da yanayin zafin jiki yayin tsarin polyerisation, ana iya rarrabe kayan pe cikin nau'ikan da yawa:
Low density proundlene (LDPE): An fi wannan nau'in kayan pe a ciki tsakanin sarƙoƙi na kwayoyin, kuma yana da ƙananan kayan kwalliya, kayan marufi, da fage gona .

Babban rauni na polyethylene (HDPE): Sarkar kwayar cuta ta HDPE ne sosai aka shirya sosai, saboda haka ya saba amfani da ƙarfi da kuma kwantiragin filaye.

Linear Low Density Polyethylene (LLDPE): LLDPE is a low density polyethylene with a linear molecular structure that combines the flexibility of LDPE with the strength of HDPE. Ana amfani dashi don yin fim mai shimfiɗa, jakunkuna na filastik da kayan marasta.

2. Manyan halaye na kayan pe
Kayan abinci suna da kyawawan abubuwan zahiri da sunadarai saboda keɓaɓɓen tsarin kwayoyin halitta, wanda ya fifita shi ta hanyar aikace-aikace da yawa:
Murmushi na sinadarai: Kayan per yana da kyakkyawan juriya ga mafi yawan acid, alkalis, salts da masana'antu da masana'antu da magunguna da magunguna.

Kyakkyawan tasirin juriya da ƙarfin tensile: HDPE, musamman ƙarfi da tsauri da iya yin amfani da su don ƙirƙirar samfurori waɗanda ke buƙatar yin tsayayya da kaya.

Kyakkyawan insulating kaddarorin: per kayan per shine kyakkyawan amfani da wutar lantarki, wanda ya sa ya zama mai amfani da Lays da wayoyi da wayoyi.

Lowyarancin sha na ruwa: kayan pe yana da karfin ruwa sosai kuma saboda haka riƙe kaddarorinta a cikin yanayin laima.

3. Abubuwan aikace-aikace na kayan pe
Godiya ga iri-iri kuma kyawawan kaddarorin, kayan pe suna taka muhimmiyar rawa a rayuwar yau da kullun da kuma masana'antu. Sanin abin da pe yake taimaka mana mu fahimci girman aikace-aikace a fannoni daban-daban:
An yi amfani da masana'antu masu fafutuka: Ana amfani da kayan pe da aka yi amfani da shi sosai wajen sarrafa filastik abinci da fina-finai na abinci da lLDPE sun dace musamman don yin kayan marufi saboda yin amfani da sassa da yawa da kuma yin amfani da su da kuma lalacewa.

Ana amfani da masana'antu da pipping masana'antu: Ana amfani da HDPE a cikin samar da bututun ruwa, bututun gas da abubuwan ƙwayar gas saboda juriya da matsi da juriya.

Kayayyakin gida: samfuran filastik yau da kullun, kamar buhun, jakunkuna masu datti da kwantena na ajiya na abinci, ana yin su daga polyethylene.

4. Kariyar muhalli da sake amfani da kayan pe
Duk da yawancin fa'idodinsa, yawan amfani da kayan pe sun kawo matsalolin matsalolin muhalli. Domin ba shi da sauƙin sauƙi, samfuran pe na iya samun mummunan tasirin abubuwa akan yanayin ƙasa. Kayan abinci na polyethylene. Ta hanyar hanyoyin sunadarai ko sunadarai, za a iya magance samfuran pe cikin sabbin abubuwa, don haka rage tasiri akan yanayin.
Ƙarshe
Ta hanyar bincike na sama, muna da cikakkun fahimta game da batun "menene kayan per". A matsayin m kayan filastik, kayan polyethylene ana amfani dashi sosai a cikin masana'antu daban-daban saboda ingantattun tsare-tsare da kyakkyawan kaddarorin. Kodayake amfani da shi yana haifar da ƙalubalen muhalli, ana iya samun ci gaban kayan pe ta hanyar sake amfani da hankali.
