Isho ukuthini iphrojekthi ye-PP P? Incazelo yamaphrojekthi e-PP P embonini yamakhemikhali
Embonini yamakhemikhali, igama elithi "PP P project" livame ukubizwa, lisho ukuthini? Lona umbuzo hhayi nje kwabaningi abasanda kuhlanganyela embonini, kodwa nalabo asebeneminyaka eminingi besebhizinisi futhi badinga ukwazi okwengeziwe ngalo mqondo. Kulesi sihloko, sizohlaziya leli temu kabanzi ukuze sisize abafundi baqonde ngokugcwele incazelo yalo kanye nokusebenza kwalo.
Okokuqala, incazelo kanye nokusetshenziswa kwe-PP
Into yokuqala okufanele uyiqonde ukuthi "PP" yilokho. I-PP iyisifinyezo se-polypropylene (i-Polypropylene), i-polymerisation ye-monomer ye-propylene evela kuma-polymers we-thermoplastic. I-Polypropylene inezakhiwo ezinhle kakhulu zomzimba namakhemikhali, njengokumelana nokushisa, ukumelana nokugqwala, amandla emishini, njll., ngakho-ke isetshenziswa kakhulu emikhiqizweni yepulasitiki, izindwangu, izimoto, ukupakisha neminye imikhakha. Emaphrojekthi amakhemikhali, ukwakhiwa nokusebenza kwezitshalo ze-PP kubaluleke kakhulu, okuthinta ngokuqondile ukuhlinzekwa kanye nekhwalithi yemikhiqizo ephansi.
Imele ini elithi “P”?
Okulandelayo, sigxila kulokho okushiwo u-“P”. “Kuphrojekthi ye-PP P”, u-“P” wesibili ngokuvamile umele isifinyezo se-“Plant”. Ngakho-ke, okushiwo iphrojekthi ye-PP P, empeleni, "iphrojekthi yesitshalo se-polypropylene". Isici esiyinhloko samaphrojekthi anjalo ukwakhiwa, ukuvuselelwa noma ukunwetshwa kwemboni yokukhiqiza i-polypropylene ukwandisa umthamo wokukhiqiza ukuhlangabezana nesidingo esikhulayo semakethe semikhiqizo ye-polypropylene.
Inqubo kanye Namaphuzu Abalulekile Ephrojekthi Ye-PP P
Umklamo ophelele we-PP P unezigaba eziningana, ngasinye sazo esibalulekile, kusukela ocwaningweni lokuthi kungenzeka yini iphrojekthi kuze kufike ekwakhiweni kwesikhungo kuya ekugunyazweni nasekusebenzeni kwayo ekugcineni. Okokuqala, kukhona ucwaningo lokungenzeka, isinyathelo esigxile ekuhloleni umnotho walo msebenzi, ukuthi kungenzeka yini umsebenzi wobuchwepheshe kanye nomthelela kwezemvelo. Bese kuza isigaba esinemininingwane sokuklama ubunjiniyela, okubandakanya ukuklanywa kwenqubo, ukukhethwa kwemishini, ukuhlela umphakathi, njll. Phakathi nesigaba sokwakha, isitshalo sidinga ukwakhiwa ngokuvumelana nohlelo lokuklama ukuze kuqinisekiswe ukuthi iphrojekthi iqedwa ngesikhathi nangekhwalithi enhle. . Okokugcina, kukhona ukugunyazwa nokuqalisa, okuyisihluthulelo sokuqinisekisa ukuthi isikhungo sisebenza ngokujwayelekile futhi sifinyelela umthamo oklanyelwe.
Izinselelo kanye nezimpendulo zamaphrojekthi we-PP P
Nakuba iphrojekthi ye-PP P inezinhlobonhlobo zezicelo embonini yamakhemikhali, kodwa inqubo yayo yokuqaliswa nayo ibhekene nezinselele eziningi. Okokuqala, ukutshalwa kwezimali okukhulu kwephrojekthi kukhulu, ngokuvamile kudinga amashumi ezigidi kuya kumakhulu ezigidi zokusekelwa kwezimali, okubeka izidingo eziphezulu esimweni sezimali somtshali wephrojekthi. Okwesibili, kulukhuni ngokwezobuchwepheshe, ikakhulukazi mayelana nokukhethwa kwemishini kanye nokwakhiwa kwenqubo, okudinga ukusekelwa yithimba lonjiniyela abanolwazi. Izindaba zezemvelo nazo ziyinselelo ebalulekile kumaphrojekthi we-PP P, okufanele ahambisane nezindinganiso zemvelo zasekhaya nezamazwe ngamazwe futhi anciphise umthelela emvelweni.
Ukuze kuhlangatshezwane nalezi zinselelo, izinkampani zivame ukusebenzisa amasu ahlukahlukene, njengokwethula ubuchwepheshe obuthuthukisiwe, ukuthuthukisa izixazululo zokuklama nokuqinisa ukuphathwa kwephrojekthi. Kudingeka futhi ukuxhumana nohulumeni kanye nomphakathi ngenkuthalo ukuze kuqinisekiswe inqubekelaphambili eshelelayo yomklamo.
V. Isiphetho
Iyini incazelo yephrojekthi ye-PP P engaqondwa kalula ngokuthi "iphrojekthi yesitshalo se-polypropylene". Lolu hlobo lwephrojekthi lunesikhundla esibalulekile embonini yamakhemikhali futhi lubandakanya zonke izici kusukela ocwaningweni lokunokwenzeka kwephrojekthi kuya ekwakhiweni kwezitshalo. Nakuba kunezinselelo eziningi, ngokuphathwa kwephrojekthi yesayensi nokusekelwa kwezobuchwepheshe, le miklamo ingaba nenzuzo enkulu enhlanganweni futhi ingaba negalelo ekukhuleni kwemboni. Uma unentshisekelo noma usebenza embonini yamakhemikhali, ukuqonda okujulile kwezici ezihlukahlukene zamaphrojekthi we-PP P kuzothuthukisa ubuchwepheshe bakho namakhono.
