Ikhoyili yensimbi ye-PPGIiyinsiza yensimbi enamayini ehlanganiswe ungqimba lwemikhiqizo enamathela ephilayo, ngenxa yezindawo zayo ezinhle kakhulu zokulwa nokugqwala, ukumelana nesimo sezulu nokubukeka okuhle, esetshenziswa kabanzi ekwakheni, ezintweni zikagesi zasendlini, ezimotweni nakwezinye izimboni. Umlando wamaroli ahlanganiswe ngombala uhlehlela emuva ekuqaleni kwekhulu lama-20 futhi ekuqaleni wawuklanyelwe ukuxazulula inkinga yokugqwala kwamapuleti ensimbi anamathangi ezindaweni ezimanzi. Ngokuvuthwa kobuchwepheshe be-galvanizing, insimbi ebilisiwe isetshenziswe kabanzi emakethe.
Ngawo-1960, umqondo weimiqulu enamabala anombalakwaqala ukuvela, futhi abakhiqizi basebenzisa ubuchwepheshe bokumboza ukuze bengeze umbala nezingqimba ezivikelayo ezingcwecweni zensimbi, ezihlangabezana nezidingo ezimbili zemakethe zobuhle nokuhlala isikhathi eside. Phakathi nalesi sikhathi, izigqoko eziyinhloko ezisetshenziswayo ziyizingubo ezisekelwe kumafutha, nakuba zinezinzuzo ezithile ekusebenzeni, kodwa ukuvikelwa kwemvelo nokuphepha kusadingeka kuthuthukiswe.
Ngeminyaka yawo-1970 kanye nawo-1980, ngokuthuthukiswa kwe-synthetic resin kanye nobuchwepheshe bokunamathela, inqubo yokukhiqiza ye-PPGI yayithuthukiswa ngokuqhubekayo, ukunamathela, ukumelana nokugqwala kanye nokumelana nesimo sezulu kwe-coating kwathuthukiswa kakhulu, futhi izinhlobonhlobo zemibala nokuthungwa kwe-coating kwavela emakethe ukuhlangabezana nezidingo zomuntu ngamunye zamakhasimende ahlukene. Ngalesi sikhathi, i-PPGI yaqala ukusetshenziswa kabanzi kuukwakha uphahla nezindonga, ekubeni yingxenye ebalulekile yezakhiwo zesimanje.
Ngemva kokungena ekhulwini lama-21, ukukhuthazwa kokuqwashisa ngemvelo emhlabeni wonke kuye kwashukumisela imboni kapende ukuba ithuthuke ekuqondeni ukuvikelwa kohlaza kanye nemvelo. Abakhiqizi abaningi sebeqala ukwamukela izigqoko ezisekelwe emanzini kanye nezingubo ze-inorganic ukuze banciphise umthelela wabo wemvelo. Lokhu kushintsha akuthuthukisi ukuphepha kwe-PPGI kuphela, kodwa futhi kuyenza ibe nokuncintisana kakhulu emakethe. Ngalesi sikhathi, inkambu yokusetshenziswa kwe-PPGI yaphinde yanwetshwa ukuze ifake izimboni eziningi ezifana nempahla yasendlini kanye nengaphakathi lezimoto, okubonisa ukuphakama kwayo ezinhlobonhlobo nokuvumelana nezimo.

Ngokuqhubeka okuqhubekayo kwesayensi nobuchwepheshe, amathuba entuthuko yesikhathi esizayo ye-PPGI abanzi. Ukwethulwa kwezinto ezintsha kanye nobuchwepheshe kuzophushela i-PPGI ekusebenzeni okuphezulu nasekuthuthukisweni okuhambisana nemvelo. Ngokugcizelelwa okwandayo ekwakheni okusimeme kanye nesakhiwo esiluhlaza, i-PPGI kulindeleke ukuthi ibambe iqhaza elikhulu kulezi zindawo.
Ngamafuphi,Imiqulu ehlanganiswe ngombala we-PPGIabe yinto ebaluleke kakhulu embonini yesimanje enezakhiwo ezinhle kakhulu zomzimba nokubukeka okuhle. Ngokuqhubeka okuqhubekayo kobuchwepheshe kanye nezinguquko ezidingekayo ezimakethe, ukusetshenziswa kwe-PPGI kuzoqhubeka nokukhula, kuletha amathuba amaningi kuzo zonke izigaba zokuphila.
