Zida zapakhomo:
M'zaka zaposachedwa, mafakitale aku China opangira zida zamagetsi m'nyumba adakula mwachangu, ndi mitundu yambiri komanso kutulutsa kwakukulu.M’chaka cha 2003, dziko la China linapanga mafiriji 18.5 miliyoni, ma air conditioner okwana 42 miliyoni, makina ochapira 17 miliyoni, ndi ma microwave okwana 35 miliyoni.Malinga ndi "2004-2006 China Urban Home Theatre Market Research and Consultation Report", akuyembekezeka kuti msika waku China wakunyumba ya zisudzo udzafika mayunitsi 6.9 miliyoni pazaka zitatu zikubwerazi.Kuphatikiza apo, zida zazing'ono zingapo zapakhomo zilinso ndi msika wawukulu womwe ungatheke, womwe ndi mwayi wabwino kwambiri wamabizinesi a PP yosinthidwa.Ena opanga mapulasitiki opangira mapulasitiki ku China apanga zida zapadera zamakina ochapira, monga PP 1947 mndandanda ndi mndandanda wa K7726, zomwe zimalandiridwa ndi opanga makina ochapira.Choncho, m'zaka zingapo zikubwerazi, chitukuko cha zipangizo zapadera za PP za zipangizo zapakhomo ziyenera kuwonjezeredwa kuti zigwirizane ndi kusintha kwa msika.
Chitoliro cha pulasitiki:
Mu 2003, dziko okwana linanena bungwe mapaipi pulasitiki kuposa matani 1.8 miliyoni, chaka ndi chaka kuwonjezeka 23%.M'masiku oyambilira, mapaipi a PP amagwiritsidwa ntchito makamaka ngati mapaipi amadzi aulimi, koma msika sunatseguke chifukwa cha zovuta zina pakuchita zinthu zoyambilira (mphamvu zamphamvu komanso kukana kukalamba).Ndi kukhazikitsidwa kwaukadaulo wapamwamba wakunja ndi Shanghai Plastic Building Equipment Factory, pambuyo poti mapaipi otumizira madzi ozizira ndi otentha opangidwa ndi zida zakunja za PP-R azindikirika ndi msika, opanga ambiri apanga mizere yopangira chitoliro cha PP-R, ndi mtengo wawonjezeredwanso ndi mzere wopanga.Mtengo woyambirira wa 20,000 mpaka 30,000 yuan / t wapitirizabe kugwa, koma gawo la msika wa mapaipi a PP-R mumsika wa pulasitiki wapaipi akadali otsika kwambiri.Malinga ndi malipoti, pali kusiyana kwina pakati pa zida zapakhomo za PP-R ndi zida zotumizidwa kunja, ndipo mtunduwo uyenera kukonzedwa ndikuwongoleredwa.Malinga ndi malipoti, South Korea yapanga kalasi yatsopano ya copolymer polypropylene PP-R 112 yamapaipi othamanga kwambiri.Mipope opangidwa ndi kalasi imeneyi angagwiritsidwe ntchito kwa zaka 50 pansi kopitilira muyeso-mkulu mavuto 20 ° C ndi 11.2 MPa.
Mapaipi apulasitiki ndi amodzi mwazinthu zofunika kwambiri pakukweza ndi kugwiritsa ntchito zida zomangira zamankhwala ku China.Unduna wa Zomangamanga udapereka "Chidziwitso Pakulimbitsa Kuwongolera Kupanga ndi Kupititsa patsogolo ndi Kugwiritsa Ntchito Mapaipi a Copolymerized Polypropylene (PP-R, PP-B)" mu 2001, wofuna kuti m'madipatimenti oyenera Agwire ntchito limodzi kuti agwire ntchito yabwino muzopangira, kukonza, khalidwe ndi ntchito chitoliro, unsembe, etc., ndi mosamalitsa kulamulira khalidwe mipope PP, kuti bwino ntchito yabwino kupanga, ntchito ndi Kukwezeleza mapaipi PP ku China.
Zinthu zowonekera kwambiri:
Ndi kuwongolera kosalekeza kwa moyo wa anthu, mosakayikira kubweretsa zofunikira zosiyanasiyana ndikusintha mbali zosiyanasiyana monga chikhalidwe, zosangalatsa, chakudya, chithandizo chamankhwala, zida, ndi kukongoletsa zipinda.Zinthu zambiri pamsika zikugwiritsa ntchito kwambiri zinthu zowonekera.Chifukwa chake, chitukuko cha zida zapadera za PP ndi njira yabwino yachitukuko, makamaka zida zapadera za PP zowonekera kwambiri, zotulutsa bwino komanso kupanga mwachangu zimafunikira kuti zipangidwe ndikusinthidwa kukhala zinthu zodziwika bwino za PP.Transparent PP ndi yodziwika bwino kuposa PP wamba, PVC, PET, PS, ndipo ili ndi zabwino zambiri komanso chiyembekezo cha chitukuko.
M'zaka zaposachedwa, msika wakunja wowonekera wa PP wakula mwachangu.Mwachitsanzo, South Korea yayambitsa PP yowonekera pamsika monga cholowa m'malo mwa PET;makampani ena a ku Germany asintha PVC ndi PP yowonekera;kukula kwa zinthu zowonekera za PP ku United States ndizokwera 7% kuposa za PP wamba ~ 9%;M'zaka zaposachedwapa, kumwa pachaka PP nucleating ndi mandala wothandizira ku Japan ndi za 2000t.Ngati ndalama zowonjezera ndi 0.25%, kutulutsa kwapachaka kwa zinthu zowonekera za PP ku Japan kumatha kufika kupitilira 800,000t.Malinga ndi kukhazikitsidwa kwa Japan Physical and Chemical Co., Ltd., zida zapadera za PP zowonekera ku Japan zimagwiritsidwa ntchito pophika ma microwave ndi mipando yomwe imagwiritsidwa ntchito kwambiri.Akuti kufunika mandala PP zipangizo zapadera m'misika yakunja mu 2005 ndi za 5 miliyoni kuti 5.5 miliyoni matani.Pali kusiyana kwakukulu pakati pa zida zapadera za PP zowonekera ndi mayiko akunja, ndipo kupanga ndi kugwiritsa ntchito utomoni wa PP wowonekera ndi zinthu zake ziyenera kulimbikitsidwa.
