NgoJulayi 12, intatheli yathola ukuthi, njengemboni eyake yaphathwa yizinkampani zakwamanye amazwe, imboni yezwe lami i-polyurethane elastomer ithuthuke ngokushesha eminyakeni yamuva, futhi isiphenduke indawo enkulu kunazo zonke emhlabeni yokukhula kwemakethe ye-polyurethane elastomer. Emhlanganweni waminyaka yonke wezi-2019 we-Elastomer Specialized Committee of China Polyurethane Industry Association obubanjelwe e-Xiamen muva nje, ochwepheshe ababambiqhaza bahlanganyele inqubekelaphambili entsha nezikhombisi-ndlela ezintsha ekusungulweni kwezobuchwepheshe be-polyurethane elastomer kanye nokuthuthukiswa komkhiqizo.

Imakethe ithuthuka ngokushesha

U-Liu Jing, unjiniyela omkhulu weKomidi le-Elastomer le-Polyurethane Association, uthe i-thermoplastic polyurethane elastomer (TPU) inokumelana okuhle kakhulu nokugqokwa, amandla aqinile aqinile, ukuphakama okuphezulu, ukumelana nowoyela, ukumelana nezinga lokushisa eliphansi, ukumelana nesimo sezulu, kanye ne-Ozone isebenza kahle kakhulu. nobulukhuni obuningi. Eminyakeni yamuva nje, iye yasetshenziswa kabanzi ezindaweni eziningi zomnotho wezwe, njengokuthunga izicathulo, ezokwelapha nempilo, nezindwangu zokugqoka.

Njengamanje, imakethe ye-TPU yomhlaba wonke igxile kakhulu eYurophu, e-United States nasesifundeni sase-Asia-Pacific. Phakathi kwazo, isifunda sase-Asia esiholwa yiChina siyimakethe yesifunda ehamba phambili nekhula ngokushesha kakhulu emhlabeni. Ngokwezibalo zeKomidi le-China Polyurethane Industry Association Elastomers Committee, ukusetshenziswa kwezwe lami kwemikhiqizo ye-polyurethane kufinyelele kumathani ayizigidi eziyi-11.3 ngo-2018, lapho ukusetshenziswa kwe-polyurethane elastomers bekungamathani ayizigidi eziyi-1.1, okubalelwa cishe ku-10% wengqikithi yokusetshenziswa kwe-polyurethanes. .

U-Lu Guohui, unobhala-jikelele we-China Polyurethane Industry Association, uthe izwe lami njengamanje lingumkhiqizi nomthengi omkhulu we-polyurethane emhlabeni. Kusukela “kuHlelo Lweminyaka Emihlanu Lweminyaka Eyi-13”, izinga lokukhula kwemboni yezwe lami ye-polyurethane selishintshile lisuka phezulu laya kwabaphansi, kanti ama-polyurethane elastomers nezinye izimakethe zingene enkathini yokuthuthuka nokwenza ngcono. , Ngasohlangothini lokusebenza okuphezulu, izinga eliphezulu, ukuvikelwa kwemvelo kanye nokusimama.

Ukukhula kwesidingo esinamandla

U-Liu Jing uthe ukukhula ngesivinini kwe-TPU kubangelwa ikakhulukazi ukuthuthukiswa kwemboni yezicathulo kanye nokwanda kwesidingo samafilimu, futhi ukusetshenziswa kwemakethe ye-TPU kuyakhula kusuka embonini yezicathulo zendabuko kuya kwezokwelapha, izindiza, ukuvikelwa kwemvelo kanye nezinye ikusasa. amathemba entuthuko. imboni. Ngokuthuthuka kwemakethe, kuwumkhuba ongenakugwemeka wokusetshenziswa kwamapulasitiki ezimbonini eziningi ukuze kuthathelwe indawo i-TPU.

U-Lu Guoguo uphinde wathi i-TPU isengomunye wemikhiqizo ye-polyurethane ekhula ngokushesha esikhathini esizayo esiseduze. Isidingo sezimpahla zezicathulo, amafilimu, amapayipi nezintambo kuzoba namandla kakhulu. Izophinde ithathe indawo yezinto ze-PVC zendabuko emkhakheni wemishini yezokwelapha, izintambo, izintambo namafilimu. Kungenzeka kakhulu ukufaka esikhundleni se-Eva emkhakheni wezinto zezicathulo. Kulindeleke ukuthi i-TPU igcine u-10% esikhathini esizayo. Noma ngaphezu komkhuba wokukhula.

Ngokusho kwemibiko, uma iqhathaniswa ne-cast polyurethane (CPU), i-TPU ngokuvamile ayidingi ukuthi ifakwe engozini futhi ixhunywe ukuze yenze imikhiqizo yokugcina, engafinyeza umjikelezo wokukhiqiza, kanye nezinto ezilahlwayo zingaphinda zisetshenziswe futhi zisetshenziswe, ezifanele ukukhiqizwa kwemikhiqizo emincane kodwa emikhulu. Eminyakeni yamuva, ingxenye ye-TPU kuma-polyurethane elastomers iye yanda unyaka nonyaka, futhi manje isifinyelele cishe ku-40%. Kulindeleke ukuthi umthamo wayo wokukhiqiza uzofinyelela kumathani angama-954,000 ngo-2019, umphumela uzofinyelela kumathani angama-590,000, futhi ukusetshenziswa kuzofinyelela kumathani angama-500,000.

Ukuqamba okusha kuyavela

Ngokukhula okuqhubekayo kwezinkambu zokufaka isicelo se-polyurethane, isidingo sokusebenza okuphezulu kanye ne-TPU esimeme siyakhula. Njengamanje, izinkampani eziningi ze-polyurethane zandisa i-R&D efanele kanye nemizamo yokusungula izinto ezintsha.

UZhao Tingwu, isekela lomqondisi weShanxi Provincial Chemical Research Institute, uthe ngokwanda kancane kancane kwezinga lokukhiqiza, izindleko zemikhiqizo ye-polyurethane elastomer zehlisiwe, izinhlobo sezihlukene kakhulu, isidingo sezimakethe sinyukile, futhi imboni isiyehlile. athuthuke ngokushesha. Emakethe yamazwe ngamazwe, izinkampani ezifana ne-Kejuya, Huntsman, Covestro, ne-Borley zinesabelo semakethe esiphezulu uma kuqhathaniswa. E-China, izinkampani ezihlanganisa i-Shanxi Chemical Research Institute, i-Suzhou Xiangyuan, i-Innovia, i-Liming Institute, ne-Wanhua Iqembu le-polyurethane elastomer R&D, ukukhiqiza kanye namabhizinisi asekelayo amelwe i-Chemical, i-Zibo Huatian, i-Shanghai Crane City, i-Jintang Technology, njll.

Njengeyunithi yokuqala eShayina ukuthuthukisa izinto ze-polyurethane elastomer, i-Shanxi Provincial Chemical Research Institute ithuthukise imikhiqizo ye-polyurethane elastomer ezokuthutha njengezinto zokudambisa i-polyurethane yokuthutha isitimela engena-ballastless, i-polyurethane. ezivezaamabhuloho, kanye namakhushini e-polyurethane abantu abalala, kanye nama-polyurethane Polyurethane elastomers emishini yezimayini efana namapuleti esisefo, amapuleti okugqoka, ama-cyclone, ama-couplings, njll.

Ukusabela esidingweni samandla avuselelekayo angasogwini, u-Covestro usungule ama-elastomer asetshenziswa ekuvikeleni izintambo ezihamba ngaphansi kolwandle namapayipi, okuhlanganisa iziqinisi zokugoba, izinqamuli zokugoba, kanye nemikhono yokuvikela ikhebula elingaphansi kwamanzi; ngamapayipi kawoyela negesi adinga ukuhlanzwa nokuhlolwa njalo, baye bathuthukisa izihlanzi zamapayipi e-Elastomer zingathuthukisa kakhulu ukumelana nokugqokwa nokumelana nowoyela, futhi zithuthukise ukuqina kwezinto.

Impahla yokufafaza ye-polyurea eyakhiwe yi-Qingdao Aierjiajia New Material Co., Ltd. ibonisa ukumelana nokushisa okuphezulu kakhulu, ukumelana nokuguga, ukulwa nokugqwala, ukunamathela okuqinile nezinye izakhiwo, futhi ifaneleka ngokukhethekile ukulwa nokugqwala, ukumelana nemigodi. , izinga eliphezulu lokuvimbela amanzi nezinye izidingo. Amaphrojekthi aphezulu, okunzima ukuwagcina.
