I-polyurethane elastomer (i-PU elastomer), eyaziwa nangokuthi irabha ye-polyurethane, iwuhlobo lwempahla ye-elastomeric polymer equkethe amaqembu e-urethane amaningi (-NHCOO-) kuchungechunge lwamangqamuzana.

Ngokuvamile kwenziwa ngama-oligomer polyols, ama-polyisocyanates, ama-chain extenders/crosslinkers kanye nenani elincane lama-agent asizayo. Nakuba ama-polyurethane elastomers anezakhiwo ezihlukene ngenxa yezinto ezingavuthiwe ezihlukene nezindlela zokukhiqiza, futhi anochungechunge lwezakhiwo ezivamile ngenxa yesakhiwo esifanayo. Isikhunta esinwebekayo se-polyurethane elastomer siphakathi kwerabha nepulasitiki. Isici esikhulu kunazo zonke ukuthi inokubili ubulukhuni obuphezulu kanye nokunwebeka okuphezulu. Lolu hlobo lokusebenza alutholakali kwamanye amarabha namapulasitiki. Ngaphezu kwalokho, ukumelana nokugqoka okuhle kakhulu kungenye yezinzuzo zayo. Ngakho-ke, ukusetshenziswa kwe-polyurethane elastomers akugcini nje ku-raber, kodwa kungenziwa kube imikhiqizo yezinto ezihlukahlukene ze-polymer.

Ukuhlaziywa kwesimo sokuthuthukiswa kwemboni ye-polyurethane elastomer

Ngokusho kwedatha "ye-Polyurethane Elastomer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" ekhishwe yiQianzhan Industry Research Institute, ngo-2016, ukusetshenziswa kwemakethe ye-polyurethane elastomer yezwe lami kwafinyelela amathani ayizigidi ezingu-1.03, ukwanda konyaka nonyaka 9.6%. Kunezinkampani ezingaba ngamakhulu embonini, ezinenani elikhulu nokuncintisana okushubile. Phakathi kwazo, kunezinkampani ezingaphezu kuka-300 zokukhiqiza izinto zokwakha nezokwakha ezweni lonke.

Kusukela ngo-2009 kuya ku-2016, ukusetshenziswa kwemakethe ye-polyurethane elastomer yezwe lami kugcine inkambiso yokukhula unyaka nonyaka. Ngo-2009-16, isilinganiso sonyaka sokukhula kwenhlanganisela ye-polyurethane elastomer ukusetshenziswa sasingu-15.3%, futhi isidingo sokusetshenziswa kwemakethe sakhula ngokushesha. Ngo-2016, ukusetshenziswa kwemakethe ye-polyurethane elastomer yezwe lami kwafinyelela amathani ayizigidi ezingu-1.03, okuwukukhula konyaka ngo-9.6%.

Ihlanganisa nokushintsha kwesimo sokusetshenziswa kwe-polyurethane elastomer yezwe lami eminyakeni yamuva kanye nezinguquko ezimakethe ezingezansi, i-Prospective Industry Research Institute ibikezela ukuthi ukusetshenziswa kwe-polyurethane elastomers kuzoqhubeka nokugcina ukukhula okusheshayo eminyakeni embalwa ezayo, kanye ne-polyurethane yezwe lami. ukusetshenziswa kwe-elastomer kuzoqhubeka nokukhula ngo-2022. Cishe amathani ayizigidi ezi-2.

Isibikezelo sephethini yokuncintisana yemakethe

Njengamanje, imboni yezwe lami i-polyurethane elastomer isesigabeni sokuthuthuka ngokushesha, inokuncintisana okwanele emakethe esezingeni eliphansi, kuyilapho imakethe esezingeni eliphezulu iphethwe izinkampani zangaphandle. Ngakolunye uhlangothi, ngaphansi kokusekelwa okuqinile kwenqubomgomo kazwelonke yezimboni, amabhizinisi asekhaya azoqhubeka nokutshala izimali ocwaningweni nasekuthuthukisweni, futhi abakhiqizi abakhulu nabasezingeni eliphakathi bazoqhubeka nokuvela, okuzoqinisa izinga lokuncintisana maphakathi nokuphela. imakethe; ngakolunye uhlangothi, amabhizinisi asekhaya azokwazi Njengoba imakethe esezingeni eliphezulu ingena ukuze ithathe ingxenye yemakethe yezinkampani zangaphandle, ukuncintisana emakethe esezingeni eliphezulu nakho kuzokhula esikhathini esizayo.

Isibikezelo sendlela yonke yomkhakha

Imboni ye-polyurethane elastomer iyimboni yokuphuma kwelanga embonini entsha yezinto ze-polymer. Isidingo somhlaba wonke sama-polyurethane elastomers siyakhula, ngesilinganiso sokukhula esiyinhlanganisela yonyaka esingaba ngu-6%. Umthamo wezimakethe zomhlaba wamanje ungafinyelela kumathani ayizigidi ezi-2.22. Nakuba imboni ye-polyurethane elastomer yaseChina iqale sekwephuzile, ithuthuke ngokushesha. Ukusetshenziswa kwamanje kwemakethe yaseShayina sekufinyelele amathani ayizigidi ezingu-1.03, futhi kakade sekudlule iYurophu ne-United States ukuze ibe imakethe yabathengi ye-polyurethane elastomer enkulu kunazo zonke emhlabeni, futhi ukusetshenziswa okujwayelekile konyaka kuye kwalondoloza cishe u-15%. Ukukhula okusheshayo kuphakeme kakhulu kunesilinganiso sokukhula saminyaka yonke sika-3-4% ezimakethe zaseYurophu nezaseMelika.

Njengamanje, njengohlobo olusha lwezinto ezibonakalayo, i-polyurethane elastomer isetshenziswe kancane kancane kuzo zonke izigaba zokuphila, futhi indima yayo iya ngokuya iba nkulu. Ngokuthuthuka kwemboni yezokwakha, imboni yezimoto, imboni yezicathulo, njll., ukuqwashisa kwabantu ngokuvikelwa kwemvelo Ngokuthuthuka kancane kancane kanye nokuvela okuqhubekayo kobuchwepheshe obusha be-polyurethane elastomers, ukusetshenziswa kwama-polyurethane elastomers kuzokwanda kakhulu. Kulindeleke ukuthi izinga lokukhula kwesidingo sama-polyurethane elastomers ezweni lami lizohlala lingaphezulu kuka-10% esikhathini esizayo.
