I-ether ye-cellulose luhlobo lwezinto eziphuma kwi-polymer yendalo, eneempawu ze-emulsification kunye nokumiswa. Phakathi kweentlobo ezininzi, i-HPMC yeyona nto iphezulu kwaye isetyenziswa kakhulu, kwaye imveliso yayo isanda ngokukhawuleza.
Kwiminyaka yakutshanje, ngenxa yokukhula koqoqosho lwelizwe, ukuveliswa kwe-cellulose ether kwilizwe lam kuye kwanda unyaka nonyaka. Ngelo xesha, kunye nophuhliso lwenzululwazi yasekhaya kunye nobuchwepheshe, i-ethers ze-cellulose eziphezulu ezifuna ekuqaleni inani elikhulu lokungeniswa kwamanye amazwe ngoku ngokuthe ngcembe lihlala kwindawo, kwaye umthamo wokuthumela ngaphandle kwee-ethers ze-cellulose zasekhaya uyaqhubeka nokukhula. Idatha ibonisa ukuba ukususela ngoJanuwari ukuya kuNovemba ka-2020, ukuthunyelwa kwe-cellulose ether yaseChina kufikelele kwiitoni ezingama-64,806, ukunyuka konyaka-ngonyaka kwe-14.2%, ephezulu kunomthamo wokuthumela ngaphandle kuyo yonke i-2019.
I-ether ye-cellulose ichatshazelwa ngamaxabiso e-cotton aphezulu:
Izixhobo eziphambili ze-cellulose ether ziquka iimveliso zezolimo kunye nezamahlathi ezibandakanya i-cotton ecocekileyo kunye neemveliso zeekhemikhali ezibandakanya i-propylene oxide. Izinto eziluhlaza zomqhaphu ococekileyo zi-cotton linters. ilizwe lam linemveliso eninzi yomqhaphu, kwaye iindawo zokuvelisa iilitha zomqhaphu zigxile kakhulu eShandong, Xinjiang, Hebei, Jiangsu nakwezinye iindawo. Iilitha zomqhaphu zininzi kakhulu kwaye zifumaneka kakhulu.
Umqhaphu uthatha indawo enkulu kuqoqosho lwezolimo, kwaye ixabiso lawo lichatshazelwa yimiba emininzi efana neemeko zendalo kunye nobonelelo kunye neemfuno zamazwe ngamazwe. Ngokufanayo, iimveliso zeekhemikhali ezifana nepropylene oxide kunye ne-methyl chloride nazo zichatshazelwa ngamaxabiso e-oyile ekrwada kumazwe ngamazwe. Ekubeni izinto eziluhlaza zithatha umlinganiselo omkhulu kwixabiso lexabiso le-ether ye-cellulose, ukuguquguquka kwamaxabiso ezinto eziluhlaza kuchaphazela ngokuthe ngqo ixabiso lentengiso ye-cellulose ether.
Ukuphendula uxinzelelo lweendleko, abavelisi be-cellulose ether bahlala bedlulisela uxinzelelo kumashishini asezantsi, kodwa umphumo wokudluliselwa uchaphazeleka kubunzima beemveliso zobugcisa, ukuhlukahluka kwemveliso kunye nexabiso lemveliso elongezelelweyo. Ngokwesiqhelo, amashishini anemiqobo ephezulu yobuchwephesha, iindidi zeemveliso ezityebileyo, kunye nexabiso elongezelelweyo eliphezulu aneenzuzo ezinkulu, kwaye amashishini aya kugcina inqanaba elizinzileyo lengeniso epheleleyo; kungenjalo, amashishini kufuneka ajongane noxinzelelo olukhulu lweendleko. Ukongezelela, ukuba imeko yangaphandle ayizinzile kwaye uluhlu lweemveliso eziguquguqukayo lukhulu, iinkampani ezinyukayo eziluhlaza zizimisele ukukhetha abathengi abasezantsi kunye nomlinganiselo omkhulu wemveliso kunye namandla abanzi anamandla okuqinisekisa iinzuzo zezoqoqosho ngexesha kunye nokunciphisa imingcipheko. Ke ngoko, oku kuthintela uphuhliso lwamashishini amancinci eselulosi ether ukuya kwinqanaba elithile.
Ulwakhiwo lweMarike esezantsi:
Ngenkqubela phambili eqhubekayo yenzululwazi kunye neteknoloji, imarike yemfuno esezantsi iya kukhula ngokufanelekileyo. Kwangaxeshanye, ububanzi bezicelo ezisezantsi kulindeleke ukuba ziqhubeke ukwanda, kwaye imfuno esezantsi iya kugcina ukukhula okuzinzileyo. Kwisakhiwo semarike esisezantsi se-cellulose ether, izinto zokwakha, ukuhlola ioli, ukutya kunye nezinye iindawo zithatha indawo enkulu. Phakathi kwabo, icandelo lezinto zokwakha yeyona marike inkulu yabathengi, ibalwa ngaphezu kwe-30%.
Ishishini lokwakha lelona candelo likhulu labathengi beemveliso zeHPMC:
Kushishino lokwakha, iimveliso ze-HPMC zidlala indima ebalulekileyo kwi-bonding kunye nokugcinwa kwamanzi. Emva kokuxuba inani elincinci le-HPMC kunye nodaka lwesamente, inokunyusa i-viscosity, i-tensile kunye ne-shear amandla e-cement mortar, i-mortar, i-binder, njl., ngaloo ndlela iphucula ukusebenza kwezinto zokwakha, ukuphucula umgangatho wokwakha kunye nokusebenza kakuhle komatshini. Ukongeza, i-HPMC ikwayi-retarder ebalulekileyo kwimveliso kunye nokuthuthwa kwekhonkrithi yorhwebo, enokuthi itshixe amanzi kunye nokuphucula i-rheology yekhonkrithi. Okwangoku, i-HPMC yeyona mveliso iphambili ye-cellulose ether esetyenziselwa ukwakha izinto zokutywina.
Ishishini lokwakha lishishini eliyintsika engundoqo kuqoqosho lwelizwe lam. Idatha ibonisa ukuba indawo yokwakhiwa kolwakhiwo lwezindlu iye yanda ukusuka kwi-7.08 yeebhiliyoni zeemitha ze-square kwi-2010 ukuya kwi-14.42 yeebhiliyoni zeemitha ze-square kwi-2019, ekhuthaze kakhulu ukukhula kwe-cellulose ether market.
Ukuchuma ngokubanzi kwishishini lezindlu nomhlaba kuye kwaphindaphindeka, kwaye indawo yokwakha kunye nokuthengisa iye yanda unyaka nonyaka. Idatha yoluntu ibonisa ukuba ngo-2020, ukuhla kwenyanga-ngonyaka kwindawo entsha yokwakha yezindlu zokuhlala kuye kwancipha, kwaye ukwehla konyaka kube yi-1.87%. Ngo-2021, imeko yokubuyisela kulindeleke ukuba iqhubeke. Ukususela ngoJanuwari ukuya kuFebruwari kulo nyaka, izinga lokukhula kwendawo yokuthengisa yezindlu zorhwebo kunye nezakhiwo zokuhlala zibuyele kwi-104.9%, oku kunyuka okukhulu.
Ukombiwa kwe-oyile:
Imarike yoshishino lweenkonzo zobunjineli bokomba ichatshazelwa ngakumbi kuphononongo lwehlabathi notyalo-mali lophuhliso, malunga nama-40% epotfoliyo yokuhlola yehlabathi enikezelwe kwiinkonzo zobunjineli bokomba.
Ngexesha lokugrumba ioyile, ulwelo lokomba ludlala indima ebalulekileyo ekuthwaleni nasekumiseni ukusika, ukomeleza iindonga zemingxuma kunye noxinzelelo lokubumba i-oyile, ukupholisa kunye nokuthambisa amasuntswana okomba, kunye nokuhambisa amandla e-hydrodynamic. Ngoko ke, kumsebenzi wokugaya ioli, kubaluleke kakhulu ukugcina umswakama ofanelekileyo, i-viscosity, i-fluidity kunye nezinye izibonakaliso zokugaya ulwelo. I-polyanionic cellulose, i-PAC, inokujiya, ithambisa i-drill bit, kwaye isasaze amandla e-hydrodynamic. Ngenxa yeemeko ezinzima zejoloji kwindawo yokugcina i-oyile kunye nobunzima bokomba, kukho imfuno enkulu yePAC.
Umzi mveliso wezinto ezincedisa amayeza:
I-Nonionic cellulose ethers isetyenziswa ngokubanzi kwishishini loxubo-mayeza njengezinto ezincedisa amayeza ezifana ne-thickeners, dispersants, emulsifiers kunye nabasunguli befilimu. Isetyenziselwa ukugquma ifilimu kunye nokuncamathelisa iipilisi zamachiza, kwaye ingasetyenziselwa ukumiswa, ukulungiswa kwamehlo, iipilisi ezidadayo, njl. intsonkothile kwaye kukho iinkqubo ezininzi zokuhlamba. Xa kuthelekiswa namanye amabanga emveliso ye-cellulose ether, izinga lokuqokelela liphantsi kwaye ixabiso lemveliso liphezulu, kodwa ixabiso elongezelelweyo lemveliso nalo liphezulu. Izinto ezincedisa amayeza zisetyenziswa kakhulu ekulungiseni iimveliso ezifana namalungiselelo ekhemikhali, amayeza elungelo elilodwa lomenzi wamaTshayina kunye neemveliso zebhayoloji.
Ngenxa yokuqalisa kade kweshishini lelizwe lam elinceda amayeza, umgangatho wangoku wophuhliso uphantsi, kwaye indlela yoshishino ifuna ukuphuculwa ngakumbi. Kwixabiso lemveliso yamalungiselelo amayeza asekhaya, ixabiso lemveliso yamayeza asekhaya libalelwa kumlinganiselo ophantsi ngokwentelekiso we-2% ukuya kwi-3%, ephantsi kakhulu kunomlinganiselo wezinto ezincedisa amayeza angaphandle, omalunga ne-15%. Inokubonwa ukuba abaxumi bamayeza basekhaya basenendawo eninzi yophuhliso., Kulindeleke ukuba ikhuthaze ngokufanelekileyo ukukhula kwemarike ye-cellulose ether ehambelanayo.
Ukususela kumbono wemveliso ye-cellulose yasekhaya ye-ether, i-Shandong Head ineyona ndawo inkulu yokuvelisa, i-akhawunti ye-12.5% yomthamo opheleleyo wemveliso, ilandelwa nguShandong RUITAI, uShandong YITENG, uMntla we-TIANPU Chemical kunye namanye amashishini. Ngokubanzi, ukhuphiswano kwishishini lubukhali, kwaye ugxininiso kulindeleke ukuba lunyuke ngakumbi.
