Kwimimandla yolwakhiwo lwezakhiwo, ukwenziwa kwezixhobo zasekhaya, kunye nokuhombisa nokuhlaziya,Ikhoyili yentsimbi yePPGLiye yaba yeyona nto ikhethwayo kwinani elikhulayo leeprojekthi ngenxa yokumelana kwayo nokugqwala kunye neempawu zokuhombisa. Nangona kunjalo, xa kukho iintlobo ngeentlobo zeemveliso zekhoyili zePPGL ezithengiswayo, indlela yokukhetha uhlobo ngokuchanekileyo, lawula ixabiso lazo.Ikhoyili yePPGL, kunye nokuqinisekisa isiphumo sokusetyenziswa kwexesha elideIshidi elinombala wePPGLzezona zinto ziphambili ezixhalabisa umthengi ngamnye.
Ikhoyili yentsimbi yePPGL yenziwa ngokusebenzisa iphepha lentsimbi eligqunywe yi-aluminium-zinc njengesixhobo esisisiseko. Emva kokususwa kwamafutha ngamakhemikhali kunye nokuguqulwa komphezulu, igqunywa ngomaleko omnye okanye ngaphezulu wezinto eziphilayo ize ibhakwe kubushushu obuphezulu ukuze inyibilike. Kolu lwakhiwo, i-aluminium-zinc coating engaphantsi isebenza njengomqobo osisiseko wokulwa nokugqwala, ngelixa i-organic coating yomphezulu yenza imisebenzi yokugquma ekhuselayo kunye nokuhombisa. Yile ndlela yokukhusela kabini ephucula kakhulu ukumelana nokugqwala kwekhoyili yePPGL, kwaye ubomi bayo bokwenyani bubude malunga ne-1.5 amaxesha kunobo bekhoyili zentsimbi eziqhelekileyo ezigqunywe yi-aluminium-zinc.

Xa uthenga iphepha elinombala wePPGL, kucetyiswa ukuba uqwalasele ezi zinto zilandelayo ngokupheleleyo: Okokuqala, ukukhethwa kohlobo lokugquma - i-polyester (PE) kufanelekile kwiindawo eziqhelekileyo zangaphakathi, i-silicone-modified polyester (SMP) ifanelekile kwiimeko zangaphandle ngokubanzi, ngelixa i-polyester enganyangekiyo yimozulu ephezulu (HDP) okanye i-polyvinylidene fluoride (PVDF) zikhetho ezikhethwayo kwiindawo ezikunxweme nakwiindawo ezinemitha enamandla ye-ultraviolet. Okwesibini, ukuhambelana kweenkcukacha ze-substrate, kubandakanya ubukhulu, ububanzi, kunye neemfuno ezenziwe ngokwezifiso zobunzima bokugquma kwe-aluminium-zinc. Okokugqibela, ukuqonda kweIxabiso lekhoyili yePPGLAkufuneki kujongwe. Ababoneleli ngeenkonzo zomgangatho kufuneka bakwazi ukubonelela ngebhalansi efanelekileyo phakathi kokuqinisekiswa komgangatho kunye nolawulo lweendleko.
Ukususela ekusekweni kwayo ekuqaleni kweminyaka yoo-1980, iQela le-ZZ lizinze kwiSithili saseYangpu, eShanghai. Ngoku likhule laba liqela elikhulu leenkampani eziquka urhwebo lwentsimbi, ukucubungula nokusasazwa kwayo, ukusebenza kwezinto eziluhlaza, uphuhliso lwezindlu kunye notyalo-mali lwezemali. Ngemali ebhalisiweyo eyi-RMB yezigidi ezingama-200, liye laba lishishini elikhokelayo kushishino lwezixhobo zesinyithi eTshayina. Eli qela lifumene iimbeko ezininzi ngokulandelelana kuquka "Amashishini Aphezulu Ayi-100 Athembekileyo kwi-National Steel Trade Logistics" kunye "Amashishini Abucala Ayi-100 Aphezulu eShanghai kwi-Steel Trade".
Ixhomekeke kwisiseko sayo esomeleleyo semizi-mveliso kunye nenkqubo yokulawula umgangatho engqongqo, i-ZZ Group iya kuqhubeka nokubonelela abathengi bethu ngeekhoyili zentsimbi zePPGL ezikumgangatho ophezulu kunye namaphepha anombala we-ppgl. Nokuba ukhathazekile malunga nomlinganiselo weendleko nokusebenza kweekhoyili ze-ppgl okanye ufuna iinkcukacha ezenzelwe wena zeekhoyili zePPGL, siya kubonelela ngeenkonzo zobungcali ukuze sikunike ixabiso.
