1. Isingeniso Esifushane Se-Cellulose Ether
I-Cellulose ether yitemu elivamile lezinhlobonhlobo zokuphuma kokunye okutholakala ku-cellulose yemvelo (ukotini ocolisisiwe kanye ne-pulp yokhuni, njll.) Umkhiqizo ophumayo uwukuphuma kokuphuma komfula ongezansi kwe-cellulose.Ngemuva kwe-etherification, i-cellulose iyancibilika emanzini, ixube isixazululo se-alkali kanye ne-organic solvent, futhi ine-thermos plasticity.Kunezinhlobo eziningi ze-cellulose ethers, ezisetshenziswa kakhulu ekwakheni, usimende, upende, imithi, ukudla, i-petroleum, amakhemikhali ansuku zonke, izindwangu, ukwenza amaphepha kanye nezingxenye ze-electronic nezinye izimboni.Ngokuya ngenani lama-substituents, ingahlukaniswa ibe yi-ether eyodwa ne-ether exutshwe, futhi ngokuya nge-ionization, ingahlukaniswa ibe ionic cellulose ether kanye ne-non-ionic cellulose ether.Njengamanje, imikhiqizo ye-ionic cellulose ether ionic inobuchwepheshe bokukhiqiza obuvuthiwe, ukulungiselela kalula, izindleko eziphansi uma kuqhathaniswa, kanye nezithiyo zezimboni eziphansi uma kuqhathaniswa.Zisetshenziswa kakhulu ezithasiselweni zokudla, izinsiza zendwangu, amakhemikhali ansuku zonke neminye imikhakha, futhi ziyimikhiqizo esemqoka emakethe.umkhiqizo.
2. Ukusetshenziswa okuyinhloko kanye nomsebenzi we-cellulose ether
Njengamanje, ama-cellulose ether ajwayelekile emhlabeni wonke yi-CMC, HPMC, MC, HEC, njll. Phakathi kwawo, i-CMC inomkhiqizo omkhulu kunayo yonke, ebalwa cishe ingxenye yomkhiqizo womhlaba wonke, kuyilapho i-HPMC ne-MC zombili zenza cishe u-33% womhlaba wonke. isidingo, futhi i-HEC yenza cishe ama-30% esidingo somhlaba wonke.I-13% yemakethe.Ukusetshenziswa kokugcina okubaluleke kakhulu kwe-carboxymethyl cellulose (CMC) okokuhlanza, okulinganiselwa ku-22% wesidingo semakethe esezansi nomfula, kanti eminye imikhiqizo isetshenziswa kakhulu emkhakheni wezinto zokwakha, ukudla nemithi.
I-Global Cellulose Ether Isidingo Sokuhlukaniswa Ngomkhiqizo
3. Izinhlelo zokusebenza eziphansi
Esikhathini esidlule, ngenxa yokuthuthukiswa okulinganiselwe kwesidingo sezwe lami se-cellulose ether emkhakheni wamakhemikhali wansuku zonke, imithi, ukudla, okokugqoka, njll., isidingo se-cellulose ether ezweni lami sasigxile kakhulu emkhakheni wezinto zokwakha.Kuze kube namuhla, imboni yezinto zokwakha isabala u-33% wesidingo se-cellulose ether yezwe lami.%.Isidingo se-cellulose ether yezwe lami emkhakheni wezinto zokwakha sesigcwele, futhi isidingo emikhakheni yansuku zonke yamakhemikhali, imithi, ukudla, okokugqoka, njll. sikhula ngokushesha ngokuthuthukiswa kobuchwepheshe bokufaka isicelo.Isibonelo, eminyakeni yamuva nje, amaphilisi ezitshalo ane-cellulose ether njengempahla eluhlaza eyinhloko, kanye nenyama yokwenziwa, umkhiqizo osafufusa owenziwe nge-cellulose ether, anamathemba okufunwa okubanzi nendawo yokukhula.
Ingxenye yesabelo semakethe esezansi nomfula esihlukile se-cellulose ether ezweni lami
Uma sithatha umkhakha wezinto zokwakha njengesibonelo, i-cellulose ether inezindawo ezinhle kakhulu ezifana nokujiya, ukugcinwa kwamanzi, nokuncipha.Ngakho-ke, i-ether yebanga lezinto zokwakha isetshenziswa kabanzi ukuthuthukisa ukukhiqizwa kodaka oluxubekile (kuhlanganise nodaka oluxutshwe olumanzi nodaka oluxutshwe okomile), i-PVC resin, njll., upende we-latex, i-putty, njll., kufaka phakathi ukusebenza imikhiqizo yokwakha.Ngenxa yokuthuthuka kwezinga lokukhula kwezwe lami emadolobheni, ukuthuthuka ngokushesha kwemboni yezinto zokwakha, ukuthuthukiswa okuqhubekayo kwezinga lemishini yokwakha, kanye nezidingo ezikhulayo zokuvikelwa kwemvelo zabathengi bezinto zokwakha kuqhubekisele phambili isidingo sama-non-ionic cellulose ethers. emkhakheni wezinto zokwakha.Ngesikhathi soHlelo Lweminyaka Eyi-13 Lweminyaka Emihlanu, izwe lami lasheshisa ukulungiswa kwemijondolo yasemadolobheni kanye nezindlu eziwohlokayo, futhi laqinisa ukwakhiwa kwengqalasizinda yasemadolobheni, okuhlanganisa nokusheshisa ukuguqulwa kwemijondolo nemizana yasemadolobheni, ngokuhlelekile nokugqugquzela ukulungiswa okuphelele kwezindawo zokuhlala ezindala, izindlu ezindala ezigugile namasethi angaphelele Ukulungiswa kabusha kwezindlu nokunye.Engxenyeni yokuqala ka-2021, indawo yezakhiwo zokuhlala ezisanda kuqaliswa yayingamamitha-skwele ayizigidi ezingama-755.15, nokunyuke ngo-5.5%.Indawo eqediwe yokwakhiwa kwezindlu ibingu-364.81 million square metres, nokunyuke ngo-25.7%.Ukubuyiselwa kwendawo eqediwe yezindlu ezithengiswayo kuzoqhuba isidingo esihlobene emkhakheni wezinto zokwakha ze-cellulose ether.
4. Iphethini yokuncintisana yemakethe
Izwe lami lingumkhiqizi omkhulu we-cellulose ether emhlabeni.Kulesi sigaba, i-ether ye-cellulose ether yempahla yokwakha yasekhaya yenziwe yasendaweni.I-Shandong HEAD iyibhizinisi elihamba phambili emkhakheni we-cellulose ether e-China.Abanye abakhiqizi abakhulu basekhaya bahlanganisa i-Shandong RUITAI, i-Shandong HEAD, i-North TIANPU Chemical, i-YICHENG Cellulose, njll. .Ngaphandle kwe-Shandong HEAD kanye nezinye izinkampani ezinamandla angaphezu kwamathani angu-10,000, kunabakhiqizi abaningi abancane be-non-ionic cellulose ethers abanomthamo wamathani angu-1,000.Ukudla okusezingeni eliphezulu kanye nemikhiqizo yebanga lemithi.
5. Ukungenisa nokuthekelisa kwe-cellulose ether
Ngo-2020, ngenxa yokwehla kwamandla okukhiqiza ezinkampani zangaphandle ngenxa yobhadane lwaphesheya kwezilwandle, umthamo wokuthekelisa we-cellulose ether ezweni lami ukhombise ukukhula ngokushesha.Ngo-2020, ukuthunyelwa kwe-cellulose ether kuzofinyelela kumathani angama-77,272.Nakuba umthamo wokuthekelisa we-cellulose ether yezwe lami ukhule ngokushesha, imikhiqizo ethunyelwa kwamanye amazwe ikakhulukazi eyakha impahla ye-cellulose ether, kuyilapho umthamo wokuthekelisa we-cellulose ether yezokwelapha kanye nebanga lokudla lincane kakhulu, futhi nenani elengeziwe lemikhiqizo ethunyelwa ngaphandle liphansi.Njengamanje, ivolumu yokuthekelisa ye-cellulose ether yezwe lami iphindwe kane kunomthamo wokungenisa, kodwa inani lokuthekelisa lingaphansi kokuphindwe kabili kwevelu yokungenisa.Emkhakheni wemikhiqizo esezingeni eliphezulu, inqubo yokuthumela ngaphandle esikhundleni se-cellulose ether yasekhaya isenayo indawo enkulu yokuthuthukiswa.
