Umhlaba wokupakisha uphuhlise ngokukhawuleza kwiminyaka yakutshanje, enolwando olubalulekileyo ekusebenziseni izixhobo eziphambili zokupakisha. Phakathi kwezi zinto zixhobo, iingxowa ze-PP eziqhwithi ziye zanda ngakumbi ngenxa yokuqina kwabo, ukungasebenzi kakuhle, kunye nokusebenza ngeendleko. Ezi zingxowa zisetyenziselwa ukupakisha uluhlu lwezixhobo ezibanzi, kubandakanya iingxowa zekhalwotium calbonate, iingxowa zesamente, kunye neengxowa ze-gypsim.

Iingxowa ze-PP ezi-PP zenziwe kwi-polyproplene, eyi-thermoplastic polymer esetyenziselwa uluhlu lwezicelo. Esi sixhobo siyaqhubeka, silula, kwaye sixhathise umswakama, eyenza ilungele ukupakisha iimveliso ezifuna ukhuseleko kwindawo engaphandle. Iingxowa ze-PP ezivuyiweyo ziyaguquguquka, ezivumela ukuba zisetyenziselwe uluhlu lweemveliso ezahlukeneyo kunye nobungakanani.

Enye yezona zinto zixhaphakileyo ze-PP eziqhwithi yeyokupakisha i-calconate, esetyenziselwa njengokuthumbuka kwiimveliso ezahlukeneyo, kubandakanya ipeyinti, iphepha kunye neplastiki. Iingxowa ezisetyenziselwa ukupakisha i-calbonate zenzelwe ukuba ziqinile kwaye zomelele, njengoko ezi zinto zinzima kwaye zifuna ibhegi eqinileyo yokuhamba kunye nokugcina.

Olunye usetyenziso lweengxowa ze-PP zeyokufaka isamente, yenye yezona zinto zisetyenziswayo zisetyenzisiweyo emhlabeni. Iingxowa zesamente zihlala zenziwa ngokudityaniswa kwephepha le-PP yelaphu kunye nephepha le-kraft, elibonelela ngokuqina kunye nokukhusela xa kusenziwa umswakama. Ezi zingxowa ziyafumaneka ngobukhulu obahlukeneyo, ukusukela kwiingxowa ezincinci zeeprojekthi ze-fuy kwiingxowa ezinkulu kwiiprojekthi zokwakha.

Iingxowa ze-PP ezi-PP zisetyenziselwa ukupakisha i-gypsum, eyimizisi ethambileyo ye-sulfarate esetyenziswe kwimveliso eyomileyo kunye ne-plaster. Iingxowa ze-Gypsim zenzelwe ukuba zincinci kwaye zilula ukujongana, njengoko zihlala zisetyenziswa kwiindawo zokwakha apho abasebenzi kufuneka bahambisane ngezixhobo ezinkulu ngokukhawuleza nangokucacileyo. Ezi zingxowa ziyaqhubeka, eziqinisekisa ukuba i-gypsum ikhuselwe kwindawo esisigxina engaphandle kwaye ihlala ihleli ngexesha lokuhamba kunye nokugcinwa.

Ukuqukumbela, iingxowa ze-PP ezilukiweyo zizinto ezibalulekileyo kwaye ziguquguqukayo kwishishini lokupakisha. Ukuqina kwabo, ukuguquguquka kwabo, kunye nokusebenza ngendleko kwenza ukuba khetha ukhetho lwemveliso, kubandakanya iingxowa zeCalwonate, iingxowa zesamente, kunye neengxowa ze-cememes, kunye neengxowa ze-cemes, kunye neengxowa ze-cememes. Ukuphuhliswa kwezinto eziphambili kunye neendlela zokuyila iindlela zokuyila ziya kuqhubeka nokuphucula ukusebenza kunye nokungaguquguquki kweengxowa ze-PP, zibenza babe yinxalenye yecandelo lePasika yanamhlanje.
