I-Cellulose ether iwuhlobo lwezinto ezitholakala ku-polymer yemvelo, enezici ze-emulsification nokumiswa. Phakathi kwezinhlobo eziningi, i-HPMC iyona ephumayo ephezulu futhi esetshenziswa kakhulu, futhi okukhiphayo kwanda ngokushesha.
Eminyakeni yamuva, ngenxa yokukhula komnotho wezwe, ukukhiqizwa kwe-cellulose ether ezweni lami kuye kwanda unyaka nonyaka. Ngesikhathi esifanayo, ngokuthuthukiswa kwesayensi nobuchwepheshe basekhaya, ama-ethers e-cellulose aphezulu ayedinga inani elikhulu lokuthengiswa kwamanye amazwe manje kancane kancane atholakala endaweni, futhi umthamo wokuthekelisa we-cellulose ethers wasekhaya uyaqhubeka nokukhula. Idatha ibonisa ukuthi kusukela ngoJanuwari kuya kuNovemba 2020, ukuthunyelwa kwe-cellulose ether yaseChina kufinyelele amathani angama-64,806, okuwukukhuphuka konyaka ngo-14.2%, okungaphezulu kwevolumu yokuthekelisa unyaka wonke ka-2019.
I-cellulose ether ithintwa izintengo zikakotini ezikhuphuka nomfula:
Izinto zokusetshenziswa eziyinhloko ze-cellulose ether zihlanganisa imikhiqizo yezolimo neyamahlathi ehlanganisa ukotini ocolisisiwe kanye nemikhiqizo yamakhemikhali kuhlanganise ne-propylene oxide. Izinto ezingavuthiwe zikakotini ocwengekile ama-linters akotini. Izwe lami linomkhiqizo omningi kakotini, futhi izindawo zokukhiqiza zikakotini zigxile kakhulu eShandong, Xinjiang, Hebei, Jiangsu nakwezinye izindawo. Ama-linter kakotini maningi kakhulu futhi atholakala kakhulu.
Ukotini uthatha ingxenye enkulu uma kuqhathaniswa nesakhiwo somnotho wezolimo, futhi intengo yawo ithintwa izici eziningi ezifana nezimo zemvelo kanye nokuhlinzekwa nokufunwa kwamazwe ngamazwe. Ngokufanayo, imikhiqizo yamakhemikhali efana ne-propylene oxide ne-methyl chloride nayo ithintwa amanani entengo kawoyela ongahluziwe. Njengoba izinto zokusetshenziswa zenza ingxenye enkulu esakhiweni sezindleko ze-cellulose ether, ukushintshashintsha kwamanani ezinto ezingavuthiwe kuthinta ngokuqondile intengo yokuthengisa ye-cellulose ether.
Ukusabela ekucindezelweni kwezindleko, abakhiqizi be-cellulose ether bavame ukudlulisela ingcindezi ezimbonini ezingezansi, kodwa umphumela wokudlulisa uthintwa ubunkimbinkimbi bemikhiqizo yezobuchwepheshe, ukuhlukahluka komkhiqizo kanye nenani lomkhiqizo elengeziwe. Imvamisa, amabhizinisi anemigoqo ephezulu yobuchwepheshe, izigaba zemikhiqizo enothile, kanye nenani eliphakeme elengeziwe anezinzuzo ezinkulu, futhi amabhizinisi azogcina izinga elizinzile lenzuzo yonke; uma kungenjalo, amabhizinisi adinga ukubhekana nengcindezi enkulu yezindleko. Ukwengeza, uma isimo sangaphandle singazinzile futhi uhla lokuguquguquka komkhiqizo lukhulu, izinkampani zempahla eluhlaza ezikhuphuka nomfula zizimisele kakhulu ukukhetha amakhasimende angaphansi komfula anezinga elikhulu lokukhiqiza namandla aphelele aqinile ukuze kuqinisekiswe izinzuzo zezomnotho ngesikhathi kanye nokunciphisa izingozi. Ngakho-ke, lokhu kunciphisa ukuthuthukiswa kwamabhizinisi amancane e-cellulose ether ngokwezinga elithile.
Isakhiwo Semakethe Ephansi:
Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imakethe yezidingo ezingezansi izokhula ngokufanele. Ngesikhathi esifanayo, ububanzi bezinhlelo zokusebenza ezingezansi kulindeleke ukuthi ziqhubeke nokukhula, futhi isidingo esingezansi sizogcina ukukhula okuqhubekayo. Esakhiweni semakethe esezansi nomfula we-cellulose ether, izinto zokwakha, ukuhlola uwoyela, ukudla nezinye izinkambu zithatha isikhundla esikhulu. Phakathi kwazo, umkhakha wezinto zokwakha uyimakethe enkulu yabathengi, ebalwa ngaphezu kwama-30%.
Imboni yezokwakha iwumkhakha omkhulu wabathengi wemikhiqizo ye-HPMC:
Embonini yezokwakha, imikhiqizo ye-HPMC idlala indima ebalulekile ekuhlanganiseni nasekugcinweni kwamanzi. Ngemva kokuxuba inani elincane le-HPMC nosimende lukasimende, lingakhuphula i-viscosity, amandla aqinile kanye ne-shear kasimende, udaka, i-binder, njll., ngaleyo ndlela ithuthukise ukusebenza kwezinto zokwakha, ithuthukise ikhwalithi yokwakha kanye nokusebenza kahle kokwakhiwa kwemishini. Ngaphezu kwalokho, i-HPMC futhi iyisivimbeli esibalulekile sokukhiqiza nokuthuthwa kukakhonkolo wezentengiselwano, ongakhiya amanzi futhi uthuthukise i-rheology kakhonkolo. Njengamanje, i-HPMC iwumkhiqizo oyinhloko we-cellulose ether osetshenziswa ekwakheni izinto zokuvala.
Imboni yezokwakha iyimboni eyinsika ebalulekile emnothweni kazwelonke wezwe lami. Imininingwane ikhombisa ukuthi indawo yokwakhiwa kokwakhiwa kwezindlu inyuke isuka ku-7.08 billion square metres ngo-2010 yaya ku-14.42 billion wamamitha-skwele ngo-2019, okukhuthaze kakhulu ukukhula kwemakethe ye-cellulose ether.
Ukuchuma okuphelele kwemboni yezindawo ezithengiswayo kuye kwaphinde kwakhula, futhi indawo yokwakha nokuthengisa iye yanda unyaka nonyaka. Idatha yomphakathi ikhombisa ukuthi ngo-2020, ukwehla konyaka nonyaka endaweni entsha yokwakhiwa kwezindlu zokuhlala zentengiso bekuncipha, kanti ukwehla konyaka kube ngu-1.87%. Ngo-2021, umkhuba wokuthola kabusha kulindeleke ukuthi uqhubeke. Kusukela kuMasingana kuya kuNhlolanja kulo nyaka, izinga lokukhula kwendawo yokuthengisa izindlu zentengiso nezakhiwo zokuhlala liphinde lafinyelela ku-104.9%, nokuwukukhula okukhulu.
Ukumba Kawoyela:
Imakethe yemboni yezinkonzo zobunjiniyela bokumba ithintwa ikakhulukazi ukutshalwa kwezimali kokuhlola nokuthuthukiswa komhlaba, cishe ngama-40% wephothifoliyo yokuhlola umhlaba wonke enikelwe emisebenzini yobunjiniyela bokumba.
Ngesikhathi sokumba uwoyela, uketshezi lokumba ludlala indima ebalulekile ekuthwaleni nasekumiseni ama-cuttings, ukuqinisa izindonga zembobo nokulinganisa ukucindezela kokwakheka, ukupholisa nokuthambisa izingcezu zokubhola, kanye nokudlulisa amandla e-hydrodynamic. Ngakho-ke, emsebenzini wokumba amafutha, kubaluleke kakhulu ukugcina umswakama ofanele, i-viscosity, i-fluidity nezinye izinkomba zokugaya uketshezi. I-polyanionic cellulose, i-PAC, ingajiya, igcobe i-drill bit, futhi idlulise amandla e-hydrodynamic. Ngenxa yezimo ze-geological eziyinkimbinkimbi endaweni yokugcina uwoyela kanye nobunzima bokumba, kunesidingo esikhulu se-PAC.
Imboni yezesekeli zemithi:
Ama-nonionic cellulose ethers asetshenziswa kakhulu embonini yezemithi njengezihlanganisi zemithi ezifana nama-thickeners, ama-disperants, ama-emulsifiers nabadali bamafilimu. Isetshenziselwa ukunamathisela ifilimu nokunamathelisa amaphilisi emithi, futhi ingasetshenziselwa ukumiswa, ukulungiswa kwamehlo, amaphilisi antantayo, njll. Njengoba i-ether ye-cellulose yezinga lezemithi inezidingo eziqinile mayelana nokuhlanzeka kanye ne-viscosity yomkhiqizo, inqubo yokukhiqiza ilinganiselwe. kuyinkimbinkimbi futhi kunezinqubo eziningi zokuwasha. Uma kuqhathaniswa namanye amabanga emikhiqizo ye-cellulose ether, izinga lokuqoqwa liphansi futhi izindleko zokukhiqiza ziphezulu, kodwa inani elingeziwe lomkhiqizo nalo liphezulu. Izinto ezisiza ekwenziweni kwemithi zisetshenziswa kakhulu emikhiqizweni yokulungiswa njengamalungiselelo amakhemikhali, imithi yamaShayina enegunya lobunikazi kanye nemikhiqizo yamakhemikhali ezinto eziphilayo.
Ngenxa yokufika sekwephuzile imboni yezwe lami esiza abantulayo, izinga lamanje lentuthuko liphansi, futhi indlela yokusebenza kwemboni idinga ukuthuthukiswa. Ngenani eliphumayo lamalungiselelo emithi yasekhaya, inani eliphumayo lezingubo zomuthi zasekhaya libalelwa engxenyeni ephansi kakhulu ka-2% kuya ku-3%, ephansi kakhulu kunengxenye yezinto ezisizayo zemithi yangaphandle, ecishe ibe ngu-15%. Kuyabonakala ukuthi abasiza bemithi basekhaya basenendawo enkulu yokuthuthuka., Kulindeleke ukuthi kugqugquzele ngempumelelo ukukhula kwemakethe ehlobene ye-cellulose ether.
Ngokombono wokukhiqizwa kwe-cellulose ether yasekhaya, i-Shandong Head inomthamo omkhulu wokukhiqiza, obala u-12.5% wenani eliphelele lokukhiqiza, lilandelwa i-Shandong RUITAI, i-Shandong YITENG, i-North TIANPU Chemical kanye namanye amabhizinisi. Sekukonke, ukuncintisana embonini kushubile, futhi ukugxila kulindeleke ukuthi kuqhubeke ukwanda.
