Izwe lokupakisha liye lathuthuka ngokushesha eminyakeni yamuva, nokwanda okukhulu kokusetshenziswa kwezinto ezithuthukisiwe zemikhiqizo yokupakisha. Phakathi kwalezi zinto zokwakha, izikhwama ezilukiwe ze-PP sezithandwa kakhulu ngenxa yokuqina kwazo, ukuguquguquka, kanye nokusebenza kahle kwezindleko. Lezi zikhwama zivame ukusetshenziselwa ukupakisha inqwaba yezinto zokwakha, okuhlanganisa izikhwama ze-calcium carbonate, izikhwama zikasimende, nezikhwama zegypsum.

Izikhwama ezilukiwe ze-PP zenziwe nge-polypropylene, okuyi-polymer ye-thermoplastic esetshenziselwa uhla lwezinhlelo zokusebenza. Le nto iqinile, ayisindi, futhi imelana nomswakama, okwenza ilungele ukupakisha imikhiqizo edinga ukuvikelwa endaweni yangaphandle. Izikhwama ezilukiwe ze-PP nazo ziyaguquguquka, ezivumela ukuthi zisetshenziselwe uhla lwemikhiqizo yomumo nosayizi abahlukene.

Enye yezinto ezisetshenziswa kakhulu izikhwama ezilukiwe ze-PP ukupakisha i-calcium carbonate, esetshenziswa njengesigcwalisi emikhiqizweni eyahlukene, okuhlanganisa upende, iphepha, namapulasitiki. Izikhwama ezisetshenziselwa ukupakisha i-calcium carbonate zenzelwe ukuthi zibe ugqinsi futhi ziqine, njengoba le nto inzima futhi idinga isikhwama esiqinile sokuthutha nokugcinwa.

Okunye ukusetshenziswa kwezikhwama ezilukiwe ze-PP ukupakisha usimende, okungenye yezinto zokwakha ezisetshenziswa kakhulu emhlabeni. Izikhwama zikasimende ngokuvamile zenziwe ngenhlanganisela ye-PP yendwangu elukiweyo nephepha le-kraft, elinikeza ukuqina nokuvikelwa kumswakama. Lezi zikhwama zitholakala ngosayizi abahlukene, kusukela ezikhwameni ezincane zamaphrojekthi we-DIY kuya ezikhwameni ezinkulu zamaphrojekthi wokwakha ezentengiselwano.

Izikhwama ezilukiwe ze-PP nazo zivame ukusetshenziselwa ukupakisha i-gypsum, okuyiminerali ye-sulfate ethambile esetshenziswa emikhiqizweni yodonga oluyi-drywall kanye ne-plaster. Izikhwama ze-Gypsum zenzelwe ukuthi zibe lula futhi ziphathwe kalula, njengoba zivame ukusetshenziswa ezindaweni zokwakha lapho izisebenzi zidinga ukuhambisa izinto eziningi ngokushesha nangempumelelo. Lezi zikhwama nazo ziqinile, okuqinisekisa ukuthi i-gypsum ivikelekile endaweni engaphandle futhi ihlala iqinile ngesikhathi sokuthutha nokugcinwa.

Sengiphetha, izikhwama ezilukiwe ze-PP ziyinto ebalulekile futhi eguquguqukayo embonini yokupakisha. Ukuqina kwazo, ukuguquguquka, kanye nokusebenza kahle kwezindleko kuzenza zibe yinketho ekhangayo yokupakisha imikhiqizo ehlukahlukene, okuhlanganisa izikhwama ze-calcium carbonate, izikhwama zikasimende, nezikhwama zegypsum. Ukuthuthukiswa kwezinto ezithuthukisiwe nezindlela ezintsha zokuklama kuzoqhubeka nokuthuthukisa ukusebenza nokuguquguquka kwezikhwama ezilukiwe ze-PP, okuzenza zibe yingxenye ebalulekile yemboni yesimanje yokupakisha.
