Ithetha ntoni iPijekthi ye-PPP? Inkcazo yeeprojekthi ze-PPP kwishishini lekhemikhali
Kumzi-mveliso wekhemikhali, igama elithi "iprojekthi" ye-PPP "idla ngokubhekiswa kuyo, kuthetha ntoni? Lo ngumbuzo nje kuphela kubabeki baninzi kwishishini, kodwa nabo babekwishishini iminyaka emininzi kwaye kufuneka bazi ngakumbi malunga naloo mxholo. Kweli nqaku, siza kulihlalutya eli gama ngokwesicelo ukunceda abafundi ukuba bayiqonde ngokupheleleyo intsingiselo kunye nesicelo.
Okokuqala, inkcazo kunye nokusetyenziswa kwe-PP
Into yokuqala yokuqonda yi "PP" yile. I-PP iPolypropylene (Polyproplene) i-Polyproplene), yipolymer polymerition ye-propylene evela kwi-thermoplastic polymers. I-Polypropylene ineepropathi ezigqwesileyo zomzimba kunye neekhemikhali, ezinjengokuxhathisa ubushushu, ukuxhathisa ubushushu, amandla omatshini, njl njl, njl njl, njl njl. Kwiiprojekthi zekhemikhali, ukwakhiwa nokusebenza kwezityalo ze-PP kubaluleke kakhulu, nto leyo echaphazela ngqo ukuhanjiswa kunye nomgangatho weemveliso zemvula.
Ithini into ethi "p"?
Emva koko, sigxile kwinto "p" imele. Kwi "PPP Projekthi", owesibini "p" idla ngokumiswa isifinyezo se "tyalo". Ke ngoko, into eyiprojekthi ye-PP yePP ye-PP ye-PP ye-PP, i-Polypropylene ". Inqaku eliphambili leeprojekthi ezinje ngolwakhiwo, ukulungiswa ngokutsha okanye ukwanda kwesityalo se-polyproplene yemveliso yokwandisa amandla emfuno yentengiso yentengiso yePolyproplenene.
Inkqubo kunye namanqaku aphambili eprojekthi yePP yePP
Iprojekthi epheleleyo ye-PP ye-PP inamanqanaba aliqela, nganye ibaluleke kakhulu, ukusuka kwisifundo seprojekthi yeprojekthi yokwakhiwa kwesityalo ukuya kwikhomishini kunye nokusebenza kwayo. Okokuqala, kukho isifundo esinokwenzeka, inyathelo eligxile ekuvavanyeni uqoqosho lweprojekthi, ukwenzeka kwezendalo kunye nefuthe lokusingqongileyo. Emva koko kuza kwinqanaba loyilo loyilo oluneenkcukacha, elibandakanya uyilo lwenkqubo, ukukhetha izixhobo, ucwangciso lwaseburhulumenteni, njl.njl. . Okokugqibela, kukho ugunyamisi kwaye aqalise-up, esona sitshixo sokuqinisekisa ukuba isityalo sisebenza ngokwesiqhelo kwaye sifikelela kumthamo owenziweyo.
Imiceli mngeni kunye neempendulo zeprojekthi ye-PPP
Nangona iprojekthi ye-PP ye-PP ye-PP inoluhlu olubanzi lwezicelo kwishishini lekhemikhali, kodwa inkqubo yokuphumeza ikwajongene nemiceli mngeni emininzi. Okokuqala, utyalomali lweprojekthi le projekthi lukhulu, ngokufuthi lufuna amashumi ezigidi ukuba zizigidi zezigidi zenkxaso yenkxaso-mali, ebeka iimfuno eziphezulu kwimo yomqeshwa yeprojekthi. Okwesibini, kunzima kakhulu, ngakumbi ngokubhekisele ekukhetheni izixhobo kunye nenkqubo yoyilo, elifuna inkxaso yeqela lezobunjineli abanamava. Imicimbi yokusingqongileyo ikwangumngeni obalulekileyo kwiiprojekthi ze-PPP, ekufuneka zihambelane nemigangatho yendalo esingqongileyo neyehlabathi kunye nokunciphisa ifuthe kwindalo esingqongileyo.
Ukuhlangabezana nemiceli mngeni, iinkampani zihlala zamkele iindlela ezahlukeneyo, ezinjengokwazisa ubuchwephesha obuphumeneyo, ukufundisa izisombululo zoyilo loyilo kunye nolawulo lweprojekthi. Kuyimfuneko ukuba unxibelelane ngenkuthalo noRhulumente kunye noluntu ukuqinisekisa inkqubela phambili egudileyo yeprojekthi.
V. ukuqhutywa
Yintoni intsingiselo yeprojekthi ye-PPP inokuqondwa nje "njengeprojekthi yezityalo zePolypropylene". Olu hlobo lweprojekthi luhlala kwindawo ebalulekileyo kwishishini lekhemikhali kwaye lubandakanya yonke imiba evela kwisifundo sokwenzeka kweprojekthi yokutyala ukutyala. Nangona kukho imiceli mngeni emininzi, kulawulo lweprojekthi yesayensi kunye nenkxaso yezobuchwephesha, ezi projekthi zinokuba ngumvuzo kakhulu kumbutho kwaye zinokuba negalelo ekukhuleni kwemveliso. Ukuba unomdla okanye usebenza kwishishini lekhemikhali, ukuqonda okunzulu kweenkalo ezahlukeneyo zeprojekthi ze-PP PP ziya kuphucula ubungcali kunye nezakhono zakho.
