Izinto zasendlini:
Eminyakeni yamuva, imboni kagesi yasendlini yaseShayina ithuthuke ngokushesha, inezinhlobonhlobo eziningi kanye nomkhiqizo omkhulu.Ngo-2003, iChina yakhiqiza iziqandisi eziyizigidi ezingu-18.5, ama-air conditioner ayizigidi ezingu-42, imishini yokuwasha eyizigidi ezingu-17, nama-oven microwave ayizigidi ezingu-35.Ngokombiko othi "2004-2006 China Urban Home Theatre Market Research and Consultation Report", kulindeleke ukuthi imakethe yezinhlelo zeshashalazi yasekhaya yaseChina ifinyelele kumayunithi ayizigidi ezingu-6.9 eminyakeni emithathu ezayo.Ngaphezu kwalokho, izinto zikagesi ezincane ezahlukahlukene zasendlini nazo zinemakethe enkulu engaba khona, okuyithuba elihle kakhulu lebhizinisi le-PP eguquliwe.Abanye abakhiqizi bezinto ezibonakalayo zepulasitiki e-China baye benza izinto ezikhethekile zemishini yokuwasha, njenge-PP 1947 uchungechunge kanye nochungechunge lwe-K7726, olwamukelwa abakhiqizi bemishini yokuwasha.Ngakho-ke, eminyakeni embalwa ezayo, ukuthuthukiswa kwezinto ezikhethekile ze-PP zemishini yasendlini kufanele kwandiswe ukuze kuhlangatshezwane nezidingo ezishintshayo zemakethe.
Ipayipi lepulasitiki:
Ngo-2003, inani eliphelele likazwelonke lokukhishwa kwamapayipi epulasitiki ladlula amathani ayizigidi eziyi-1.8, okuwukukhula konyaka ngama-23%.Ezinsukwini zakuqala, amapayipi e-PP ayesetshenziswa kakhulu njengamapayipi amanzi ezolimo, kodwa imakethe yehlulekile ukuvuleka ngenxa yezinkinga ezithile ekusebenzeni kwemikhiqizo yokuqala (amandla omthelela kanye nokungagugi kahle).Ngokwethulwa kobuchwepheshe obuthuthukile bakwamanye amazwe yiShanghai Plastic Building Materials Factory, ngemuva kokuba amapayipi okudlulisa amanzi abandayo nashisayo akhiqizwe yi-PP-R materials angenisiwe aqashelwe yimakethe, abakhiqizi abaningi bakhe imigqa yokukhiqiza ipayipi le-PP-R, futhi intengo nayo inyuswe ngomugqa wokukhiqiza.Intengo yokuqala ye-20,000 kuya ku-30,000 yuan/t iqhubekile nokuwa, kodwa isabelo semakethe samapayipi e-PP-R emakethe yamapayipi epulasitiki sisaphansi kakhulu.Ngokwemibiko, kusekhona igebe elithile phakathi kwezinto zasekhaya ze-PP-R nezinto ezithunyelwa kwamanye amazwe, futhi ikhwalithi idinga ukuthuthukiswa nokuthuthukiswa.Ngokwemibiko, iNingizimu Korea ithuthukise ibanga elisha le-copolymer polypropylene PP-R 112 elingahleliwe lamapayipi okuhambisa amanzi anengcindezi ephezulu.Amapayipi akhiqizwa yileli banga angasetshenziswa iminyaka engu-50 ngaphansi kwezimo ze-ultra-high of 20 ° C kanye ne-11.2 MPa.
Amapayipi epulasitiki angeminye yemikhiqizo esemqoka yokugqugquzela nokusebenzisa izinto zokwakha zamakhemikhali eChina.UMnyango Wezokwakha ukhiphe "Isaziso Sokuqinisa Ukuphathwa Kokukhiqiza Nokukhuthaza kanye Nokusetshenziswa Kwemibhobho Ye-Copolymerized Polypropylene (PP-R, PP-B)" ngo-2001, edinga iminyango efanele Isebenzisana ukuze yenze umsebenzi omuhle ezintweni ezingavuthiwe, ukucubungula, izinga kanye nokusetshenziswa kwamapayipi, ukufakwa, njll., nokulawula ngokuqinile ikhwalithi yamapayipi e-PP, ukuze wenze kangcono umsebenzi omuhle ekukhiqizeni, ekusetshenzisweni nasekukhuthazeni amapayipi e-PP e-China.
Izinto ezibonisa ngale kakhulu:
Ngokuthuthuka okuqhubekayo kwamazinga okuphila abantu, nakanjani kuzoletha izidingo nentuthuko ehlukene emikhakheni eyahlukene njengamasiko, ukuzijabulisa, ukudla, ukunakekelwa kwezokwelapha, izinto zokwakha, kanye nokuhlobisa igumbi.Izinto eziningi emakethe ziya ngokuya zisebenzisa izinto ezibonakalayo.Ngakho-ke, ukuthuthukiswa kwezinto ezikhethekile ze-PP esobala kuwumkhuba omuhle wokuthuthuka, ikakhulukazi izinto ezikhethekile ze-PP ezinokucaca okuphezulu, uketshezi oluhle kanye nokwakheka okusheshayo kuyadingeka ukuze yakhelwe futhi icutshungulwe ibe yimikhiqizo edumile ye-PP.I-PP esobala igqame kakhulu kune-PP evamile, i-PVC, i-PET, i-PS, futhi inezinzuzo eziningi namathemba entuthuko.
Eminyakeni yamuva, imakethe ye-PP esobala yangaphandle ikhule ngokushesha.Isibonelo, iSouth Korea yethule i-PP esobala emakethe njengebambela i-PET;ezinye izinkampani zaseJalimane zithathe indawo ye-PVC nge-PP esobala;izinga lokukhula kwemikhiqizo ye-PP esobala e-United States iphakeme ngo-7% kunemikhiqizo evamile ye-PP~ 9%;Eminyakeni yamuva, ukusetshenziswa kwaminyaka yonke kwe-PP nucleating kanye ne-ejenti esobala eJapane cishe ku-2000t.Uma inani elingeziwe lingu-0.25%, umphumela wonyaka wezinto ezibonakalayo ze-PP e-Japan zingafinyelela ngaphezu kuka-800,000t.Ngokusho kokwethulwa kwe-Japan Physical and Chemical Co., Ltd., izinto ezikhethekile ze-PP zase-Japan ezibonisa ngale zisetshenziswa ezikolweni zama-microwave kanye nefenisha esetshenziswa kakhulu.Kulinganiselwa ukuthi isidingo sezinto ezikhethekile ze-PP esobala ezimakethe zakwamanye amazwe ngo-2005 singamathani ayizigidi ezi-5 kuya kwezingu-5.5.Kunegebe elikhulu phakathi kwezinto ezikhethekile ze-PP esobala zasekhaya kanye namazwe angaphandle, futhi ukukhiqizwa nokusetyenziswa kwe-PP resin esobala kanye nemikhiqizo yayo kusadingeka kuqiniswe.
