Konke esikwenzayo kuxhomekeke kwimfundiso yethu. Umthengi oza kuqala, thembela ekupakisheni ukutya kunye nokukhusela okusingqongileyo kwimveliso entsha yaseTshayina. Iipayipi ze-UPVC kunye nokufakelwa, Ngenxa yomgangatho ophezulu kunye nexabiso lokuthengisa elinamandla, siya kuba yinkokeli kwimarike, qiniseka ukuba awulindi ukunxibelelana nathi ngefowuni okanye nge-imeyile, ukuba unomdla kuyo nayiphi na imveliso yethu.
Konke esikwenzayo kudla ngokunxulunyaniswa nemfundiso yethu. "Umthengi oza kuqala ngaye, Thembela ekufakweni kokutya kunye nokukhuselwa kwendalo.Izixhobo zokwakha, Ukulinganisa iPVC yaseTshayina, Silwela ukugqwesa, ukuphuculwa rhoqo kunye nokuvelisa izinto ezintsha, sizimisele ukusenza "intembeko yabathengi" kunye "nokhetho lokuqala lwababoneleli bezixhobo zoomatshini bobunjineli". Sikhethe, sabelana ngemeko ephumelela kumacala omabini!

1) Umbhobho wePVC kunye nokufakelwa kokufakelwa

Iimbonakalo
Ayinatyhefu: akukho zongezo zesinyithi esinzima
Iyamelana nokugqwala: iyamelana nezinto zeekhemikhali, ukugqwala kweekhemikhali ze-electron okanye ukugqwala
Iindleko zoFakelo eziphantsi: ubunzima obuphantsi kunye nokulula kokufakela
Iindonga zangaphakathi ezithambileyo: ukungqubana okuphantsi kunye nomthamo ophezulu kuneepayipi zesinyithi
Ubomi obude: ngaphezu kweminyaka engama-50 phantsi kweemeko eziqhelekileyo
Iphinde yasetyenziswa kwakhona kwaye inobuhlobo nokusingqongileyo

Izicelo
imibhobho yokukhupha umhlaba kunye nenkunkuma ngaphakathi kwisakhiwo
imibhobho yamanzi emvula ngaphakathi kwesakhiwo
imibhobho yokukhupha amanzi egqunywe ngaphandle koxinzelelo emhlabeni

2) Iingenelo zombhobho wePVC kunye nokufakelwa kwawo

1. Ubunzima obulula: ubunzima obukwiyunithi ubude yi-1/6 kuphela yemibhobho yesinyithi esenziwe ngentsimbi.
2. Amandla aphezulu: amandla okutsalwa afikelela kwi-45 Map.
3. Ukumelana okuphantsi: udonga olungaphakathi lugudileyo kwaye luthintela ukwakheka kwe-scum. Uxinzelelo lwamanzi kunye nokukhutshwa kombhobho we-PVC-U kuphantsi ngama-30% kunemibhobho yesinyithi esibunjiweyo enobubanzi obufanayo kwaye kunokonga iindleko zamandla okukhupha.
4. Ukumelana nokugqwala: ukumelana okugqwesileyo nokugqwala okubangelwa zii-asidi, i-alkaline, iikhemikhali kunye nombane, nto leyo ebangela ukuba kungabikho mabala.
5.Ukufakela okulula: kudibanisa lula ngeeringi zerabha. Kulula ukuyifaka kwaye ivala kakuhle.
6.Ixesha elide lokuphila: phantsi kweemeko eziqhelekileyo ixesha lokuphila linokufikelela kwiminyaka engama-50.
7. Ixabiso eliphantsi: ngexabiso eliphantsi lokufakela. Uthutho kunye nezinto eziluhlaza, ixabiso lilonke lobunjineli lenza i-PVC-U ibe ngaphantsi ngama-30% kuneepayipi zesinyithi. Konke esikwenzayo kuxhomekeke kwimfundiso yethu. Umthengi oza kuqala, thembela ekufakweni kokutya kunye nokukhuselwa kwendalo kwiMibhobho/Iipipe ze-UPVC zeMveliso eNtsha yaseTshayina, Ngenxa yomgangatho ophezulu kunye nexabiso lokuthengisa elinamandla, siya kuba yinkokeli yemarike, qiniseka ukuba awulindi ukunxibelelana nathi ngefowuni okanye nge-imeyile, ukuba unomdla phantse kuyo nayiphi na imveliso yethu.
Imveliso Entsha yaseTshayina Ukufakelwa kwePVC yaseTshayina, Izinto zokwakha, Silwela ukugqwesa, ukuphuculwa rhoqo kunye nokuvelisa izinto ezintsha, sizimisele ukusenza "sithembeke kubathengi" kunye "nokukhethwa kokuqala kwababoneleli bezixhobo zoomatshini bobunjineli". Sikhethe, sabelana ngemeko ephumelela kumacala omabini!
