I-Cellulose EtherYigama elijwayelekile lezinhlobonhlobo zokutholwa ezitholwe kwi-cellulose yemvelo (ukotini ocwengekile kanye ne-solip ye-wood, njll.) Umkhiqizo ophumelelayo uvela phansi kwe-cellulose. Ngemuva kokuthethezeka, iselulamevu incane emanzini, i-dilite alkali solution kanye ne-organic solvent, futhi ine-thermoplasticity. Kunezinhlobo eziningi ze-cellulose afers, ezisetshenziswa kabanzi ekwakheni, usimende, upende, umuthi, ukudla, uphethroleum, amakhemikhali amakhemikhali nsuku zonke, izindwangu, ukuphazamiseka kanye nezimboni. Ngokuya ngenani lokufakwa esikhundleni, lingahlukaniswa libe yi-ether eyodwa ne-ether elixubile, futhi ngokusho kwe-ionization, lingahlukaniswa libe yi-ionic cellulose ether ne-non-iolic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-ionic cellulose ether kanye ne-non-iolic cellulose ether kanye ne-non-iolic cellulose ether ne-ether engekho. Njengamanje, ama-ionic cellulose ether ionic imikhiqizo inobuchwepheshe bokukhulisa abavuthiwe, ukulungiselela okulula, izindleko eziphansi kakhulu, kanye nezithiyo eziphansi zezimboni. Zisetshenziswa kakhulu ezithangekweni zokudla, izindwangu ze-auxiliaries, amakhemikhali nsuku zonke nakweminye imikhakha, futhi yimikhiqizo esemqoka emakethe.
Njengamanje, izitha ze-mobulerose ezijwayelekile emhlabeniCMC, HPMC, MC, HEC, njll. Phakathi kwazo, i-CMC inomphumela omkhulu kunayo yonke, i-accounting cishe ingxenye ye-Global Output, ngenkathi i-HPMC ne-akhawunti ye-MC ye-33% yesidingo sembulunga yonke, futhiI-HECama-akhawunti acishe abe ngu-50% wesidingo sembulunga yonke. I-13% yemakethe. Ukusetshenziswa okubaluleke kakhulu kwe-carboxymethylllyl celtulose (CMC) kuyinto yokuhlanza, ukubalwa kwemali cishe ngo-22% wesidingo semakethe esiphansi, neminye imikhiqizo isetshenziswa ikakhulukazi emikhakheni yezinto zokwakha, ukudla nomuthi.
Izicelo eziphansi
Esikhathini esedlule, ngenxa yokuthuthuka okulinganiselwe kwesidingo sezwe lami se-cellulose ether emikhakheni yamakhemikhali nsuku zonke, umuthi, ukudla, ukumboza, njll. Isidingo seCellulose Ether eChina. Kuze kube namuhla, imboni yokwenza izinto zokwakha isamaka-33% we-ether ye-cellulose yezwe lami. Isidingo se-ether ye-cellulose yezwe lami emkhakheni wezinto zokwakha sesisusiwe, futhi ukufunwa emikhakheni yamakhemikhali nsuku zonke, umuthi, ukudla, ukumboza, njll. Kukhula ngokushesha ngokuthuthuka kobuchwepheshe bohlelo lokusebenza. Isibonelo, eminyakeni yamuva nje, amaphilisi wemifino ephethe i-cellulose ether njengento esetshenziswayo eluhlaza, nenyama yokufakelwa, umkhiqizo ovelayo owenziwe nge-cellulose ether, ube nethuba elibanzi lokukhula.
Ukuthatha insimu yezinto zokwakha njengesibonelo, i-cellulose ether inezakhiwo ezinhle kakhulu njengokuqina, ukugcinwa kwamanzi kanye nokubuyiselwa emuva. Ngakho-ke, ukwakha Ibanga le-cellulose ether kusetshenziswa kabanzi ukuthuthukisa ukukhiqizwa kodaka oluhlanganisiwe (kufaka phakathi nodaka oluxutshwe nodaka oluxutshwe, njll., Njll. Ngenxa yokuthuthukiswa kweleveli yezwe lasekuqaleni izwe, ukuthuthukiswa okusheshayo kwemikhakha yokwakha, kanye nokuthuthuka okwandayo kwemvelo kwabathengi bezimali zokwakha kuqhubelwe isidingo se-Nonic Cellulose Afers. Ngesikhathi sezinkathi zesikhathi seminyaka eyi-13, izwe lami lasheshisa ukuguqulwa kwama-Urban Shantytown kanye nezindlu ezincishisiwe, futhi kwaqinisa ukuguqulwa kwengqalasizinda yasemadolobheni, kuqhume ukulungiswa kabusha kwezindlu ezindala zokuhlaselwa kwezindlu ezindala, izindlu ezindala zesethi nokuningi. Engxenyeni yokuqala ka-2021, indawo yezakhiwo ezazisanda kuqalwa ezifuywayo yayingamamitha-skwele angama-755.15, ukukhuphuka kwe-5.5%. Indawo egcwalisiwe yezindlu yayingamamitha ayi-364.81 million, ukukhuphuka kwama-25,7%. Ukubuyiselwa kwendawo eqediwe ye-Real Estate kuzoshayela ukufunwa okuhlobene emkhakheni wezinto zokwakha zokwakha ze-cellulose ether.
Iphethini yokuncintisana yemakethe
Izwe lami lingumkhiqizi omkhulu we-cellulose ether emhlabeni. Kulesi sigaba, ibanga lesicelo sezakhiwo zasekhaya I-Cellulose Ether sezakhiwe ngokwezifiso. UShandong Heda uyibhizinisi eliholayo emkhakheni we-Cellulose Ether eChina. Eminye abakhiqizi abasemakhaya abasemakhaya bafaka uShandong Ruitai, uShandong Yiteng, kanye neNorth TiaPu Chelmical, njll. Ngaphezu kukaShandong Heda nezinye izinkampani ezinomthamo wamathani angaphezu kuka-10,000, kunabakhiqizi abaningi abancane bokuphatha kabi okungewona amathanga ayi-1 000. Ukudla okuphezulu kokudla kanye nemikhiqizo yebanga lemithi.
Ngenisa kanye nokuthumela ngaphandle kwe-ether ye-cellulose
Ngo-2020, ngenxa yokwehla kwamandla okukhiqiza izinkampani zakwamanye amazwe ngenxa yobhubhane lwaphesheya ngenxa yobhubhane lwaphesheya, ivolumu yokuthekelisa ye-cellulose ether ezweni lami ikhombise inkambiso yokukhula ngokushesha. Ngo-2020, ukuthekelisa kwe-cellulose ether kuzofinyelela amathani angama-77,272. Yize ivolumu yokuthumela kwelinye izwe lamiI-Cellulose EtherIkhule ngokushesha, imikhiqizo ethunyelwayo ikakhulukazi yokwakha impahla ye-cellulose ether, kuyilapho ivolumu yokuthekelisa yezokwelapha kanye nebanga le-cellulose incane kakhulu, futhi inani elingeziwe lemikhiqizo yokuthumela ngaphandle. Njengamanje, ivolumu yokuthekelisa ye-cellulose ether yami yezwe lami liphindwe kane ivolumu yokungenisa, kepha inani lokuthumela lingaphansi kwenani lokungenisa. Emkhakheni wemikhiqizo ephezulu kakhulu, inqubo yokufaka ukuthembela kwamanye amazwe ye-Pureturose Ether isenendawo eningi yokuthuthuka.
