Umhlaba wokupakisha usuthuthukile ngokushesha eminyakeni yamuva nje, ngokwanda okukhulu kokusetshenziswa kwezinto ezithuthukile zemikhiqizo yokupakisha. Phakathi kwalezi zinto zokwenziwa, izikhwama ezilukiwe ze-PP ziye zathandwa kakhulu ngenxa yokuqina kwazo, ukuguquguquka, kanye nokusebenza kwezindleko. Lezi zikhwama zivame ukusetshenziselwa ukupakisha uhla olubanzi lwezinto zokwakha, kufaka phakathi izikhwama ze-calcium carbonate, izikhwama zikasimende, kanye nezikhwama ze-gypsum.

Izikhwama ezilukiwe ze-PP zenziwa nge-polypropylene, okuyi-polymer ye-thermoplastic esetshenziselwa uhla lwezicelo. Lokhu okuhlala isikhathi eside, kungasindi, futhi kungamelana nomswakama, okwenza kube yinto elungele ukupakisha imikhiqizo edinga ukuvikelwa endaweni yangaphandle. Izikhwama ezilukiwe ze-PP nazo zivumelana nezimo, ezibavumela ukuthi zisetshenziselwe uhla lwemikhiqizo ehlukene nobukhulu.

Okunye ukusetshenziswa okuvame kakhulu kwezikhwama ezilukiwe ze-PP kungokufaka i-calcium calbonate, esetshenziswa njengomfutho emikhiqizweni ehlukahlukene, kufaka phakathi upende, iphepha namapulasitiki. Izikhwama ezisetshenziselwa ukupakisha i-calcium calbonate zenzelwe ukuba zibe mnene futhi ziqine, njengoba lokhu kusebenza kunzima futhi kudinga isikhwama esiqinile sokuhamba nokugcinwa.

Okunye ukusetshenziswa kwezikhwama ezilukiwe ze-PP kungokwesimende yokupakisha, okungenye yezinto ezisetshenziswa kakhulu zokwakha emhlabeni. Izikhwama zikasimende zivame ukwenziwa ngokuhlanganiswa kwendwangu elukiwe ye-PP ne-Kraft, enikeza ukuqina nokuvikelwa kumswakama. Lezi zikhwama zitholakala ngosayizi ohlukile, ezisukela ezikhwameni ezincane zamaphrojekthi we-DIY ezikhwameni ezinkulu zamaphrojekthi wokwakha ezentengiselwano.

Izikhwama ezilukiwe ze-PP nazo zisetshenziselwa ukupakisha i-gypsum, okuyinto amaminerali athambile we-sulfate asetshenziswa emikhiqizweni e-drywall ne-plaster. Izikhwama ze-Gypsum zenzelwe ukungasindi futhi kube lula ukuzisingatha, ngoba zivame ukusetshenziswa ezindaweni zokwakha lapho abasebenzi badinga ukuhambisa inqwaba yezinto zokwakha ngokushesha nangendlela efanele. Lezi zikhwama nazo zihlala isikhathi eside, eziqinisekisa ukuthi i-gypsum ivikelekile emvelweni yangaphandle futhi isaqhubeka nokuhamba ngesikhathi sokuhambisa nokugcinwa.

Ekuphetheni, izikhwama ezilukiwe ze-PP ziyinto ebalulekile futhi eguquguqukayo embonini yokufaka. Ukuqina kwabo, ukuvumelana nezimo, nokusebenza kahle kwezindleko kubenza babe yisinqumo esikhangayo sokupakisha imikhiqizo ehlukahlukene, kufaka phakathi izikhwama ze-calcium carbonate, izikhwama zikasimende, kanye nezikhwama ze-gypsum. Ukuthuthukiswa kwezinto ezithuthukisiwe kanye namasu okuklama amasha azoqhubeka nokuthuthukisa ukusebenza nokuguquguquka kwezikhwama ezilukiwe ze-PP, ezibenza babe yingxenye ebalulekile yemboni yesimanje yokufaka embonini.
