Ihlabathi lokupakisha liye laphuhliswa ngokukhawuleza kwiminyaka yakutshanje, ngokunyuka okukhulu kokusetyenziswa kwezinto eziphambili zokupakisha iimveliso. Phakathi kwezi zixhobo, iingxowa ezilukiweyo zePP ziye zanda kakhulu ngenxa yokuqina kwazo, ukuguquguquka, kunye nokusebenza kakuhle kweendleko. Ezi ngxowa ziqhele ukusetyenziselwa ukupakisha uluhlu olubanzi lwezixhobo, kubandakanya iingxowa ze-calcium carbonate, iingxowa zesamente, kunye neengxowa zegypsum.

Iingxowa ezilukiweyo zePP zenziwe ngepolypropylene, eyipolymer ye-thermoplastic esetyenziselwa uluhlu lwezicelo. Esi sixhobo sihlala siqinile, sikhaphukhaphu, kwaye sichasene nokufuma, okwenza kube yinto efanelekileyo yokupakisha iimveliso ezifuna ukukhuselwa kwimeko yangaphandle. Iingxowa ezilukiweyo zePP nazo zibhetyebhetye, ezivumela ukuba zisetyenziswe kuluhlu lweemveliso zeemilo ezahlukeneyo kunye nobukhulu.

Enye yezona zinto ziqhelekileyo zokusetyenziswa kweengxowa ezilukiweyo zePP kukupakisha i-calcium carbonate, esetyenziswa njengesizaliso kwiimveliso ezahlukeneyo, kubandakanya ipeyinti, iphepha, kunye neeplastiki. Iingxowa ezisetyenziselwa ukupakisha i-calcium carbonate zenzelwe ukuba zibe ngqindilili kwaye zomelele, njengoko le nto inzima kwaye ifuna isikhwama esomeleleyo sokuthutha kunye nokugcinwa.

Olunye usetyenziso lweengxowa ezilukiweyo zePP kukupakisha isamente, yenye yezona zinto zisetyenziswa kakhulu emhlabeni. Iingxowa zesamente zihlala zenziwe ngokudityaniswa kwelaphu elilukiweyo lePP kunye nephepha le-kraft, elibonelela ngokuzinzileyo kunye nokukhuselwa kumswakama. Ezi ngxowa zifumaneka ngobukhulu obahlukeneyo, ukusuka kwiingxowa ezincinci kwiiprojekthi ze-DIY ukuya kwiingxowa ezinkulu kwiiprojekthi zokwakha zorhwebo.

Iingxowa ezilukiweyo zePP zikwaqhele ukusetyenziselwa ukupakisha igypsum, eyiminerali ethambileyo yesulfate esetyenziswa kwidrywall kunye neemveliso zodaka. Iingxowa zeGypsum ziyilelwe ukuba zibe khaphukhaphu kwaye kube lula ukuziphatha, njengoko zihlala zisetyenziswa kwiindawo zokwakha apho abasebenzi kufuneka bahambise izinto ezininzi ngokukhawuleza nangokufanelekileyo. Ezi ngxowa zikwahlala ixesha elide, eliqinisekisa ukuba i-gypsum ikhuselwe kwindawo yangaphandle kwaye ihlala ilungile ngexesha lokuthutha nokugcinwa.

Ukuqukumbela, iingxowa ezilukiweyo zePP zizinto ezibalulekileyo neziguquguqukayo kwishishini lokupakisha. Ukuqina kwabo, ukuguquguquka, kunye nokusebenza kakuhle kweendleko kubenza kube yinto ekhangayo yokupakisha iimveliso ezahlukeneyo, kubandakanya iingxowa ze-calcium carbonate, iingxowa zesamente, kunye neengxowa zegypsum. Uphuhliso lwemathiriyeli ephucukileyo kunye nobuchule bokuyila obutsha buya kuqhubeka nokuphucula ukusebenza kunye nokuguquguquka kweengxowa ezilukiweyo zePP, zizenza yinxalenye ebalulekileyo yoshishino lokupakisha lwangoku.
