1. Imiba evumayo
(1) Inkxaso yomgaqo-nkqubo
Njengesixhobo esitsha esisekwe kwindalo kunye nezinto eziluhlaza kunye nokusingqongileyo, ukusetyenziswa okubanzi kwei-cellulose etherkwinkalo yoshishino yindlela yophuhliso lokwakha uluntu olunobuhlobo nokusingqongileyo kunye nokugcina ubutyebi kwixesha elizayo. Uphuhliso lweshishini luhambelana nenjongo enkulu yelizwe lam yokuphumeza uphuhliso loqoqosho oluzinzileyo. Urhulumente waseTshayina uye wakhupha ngokulandelelana imigaqo-nkqubo kunye nemilinganiselo efana ne "National Medium and Long-Term Science and Technology Development Plan (2006-2020)" kunye "noShishino loKwakha "iSicwangciso seMinyaka emihlanu yeSicwangciso soPhuhliso" ukuxhasa ishishini le-cellulose ether.
Ngokutsho kwe "2014-2019 China Pharmaceutical Food Grade Cellulose Ether Market Monitoring and Investment Prospect Analysis Report" ekhutshwe yiChina Industry Information Network, ilizwe liye laqulunqa imigangatho engqongqo yokukhuselwa kwendalo, eye yaphakamisa ugxininiso kwimiba yokhuseleko lokusingqongileyo kwindawo entsha. inqanaba. Izohlwayo ezikhulu zongcoliseko lokusingqongileyo zidlale indima entle ekusombululeni iingxaki ezifana nokhuphiswano olungalungelelananga kwishishini le-cellulose ether kunye nokudibanisa amandla okuvelisa ishishini.
(2) Ithemba lezicelo ezisezantsi zibanzi kwaye imfuno iyanda
I-cellulose ether yaziwa ngokuba yi "industrial monosodium glutamate" kwaye ingasetyenziswa kwiinkalo ezahlukeneyo zoqoqosho lwesizwe. Uphuhliso loqoqosho luya kuqhuba ngokungenakuthintelwa ukukhula koshishino lwe-cellulose ether. Ngophuhliso oluqhubekayo lwenkqubo yelizwe lam lokuhlala ezidolophini kunye notyalo-mali olomeleleyo lukarhulumente kwizinto zexabiso ezisisigxina kunye nezindlu ezifikelelekayo, ishishini lokwakha kunye nezixhobo zokwakha liyakwandisa kakhulu imfuno ye-cellulose ether. Kwiinkalo zamayeza kunye nokutya, ukuqonda kwabantu ngempilo kunye nokukhuselwa kwendalo kuyanda ngokuthe ngcembe. Iimveliso ze-cellulose ze-ether ezingenabungozi ngokwasemzimbeni kunye nezingangcolisiyo ezifana ne-HPMC ziya kuthatha indawo yezinye izinto ezikhoyo kwaye ziphuhlise ngokukhawuleza. Ukongezelela, ukusetyenziswa kwe-cellulose ether kwiingubo, i-ceramics, izimonyo, isikhumba, iphepha, i-rubber, iikhemikhali zemihla ngemihla kunye namanye amashishini ayanda ngakumbi.
(3) Inkqubela phambili yezobuchwephesha iqhuba uphuhliso lweshishini
Kwinqanaba lokuqala lophuhliso loshishino lwelizwe lam lwecellulose ether, ionic carboxymethyl cellulose ether (CMC) yayiyeyona mveliso iphambili. Ngokwenziwa kwe-ionic cellulose ether emelwe yiPAC kunye ne-non-ionic cellulose ether emelwe yi-HPMC Ngophuhliso kunye nokuvuthwa kwenkqubo, intsimi yesicelo se-cellulose ether iye yandiswa. Ubuchwephesha obutsha kunye neemveliso ezintsha ziya kutshintsha ngokukhawuleza iimveliso ze-ether zeselulosi kwixesha elidlulileyo kwaye zikhuthaze uphuhliso loshishino.
2. Imiba engathandekiyo
(1) Ukhuphiswano olungalunganga kwimarike
Xa kuthelekiswa nezinye iiprojekthi zeekhemikhali, ixesha lokwakhiwa kweprojekthi ye-cellulose ether lifutshane kwaye iimveliso zisetyenziswa ngokubanzi, ngoko kukho into yokwandiswa kokuphazamiseka kwishishini. Ukongeza, ngenxa yokunqongophala kwemigangatho yoshishino kunye nemimiselo yemarike equlunqwe ngurhulumente, kukho amashishini amancinci anezinga eliphantsi lobugcisa kunye notyalo-mali olulinganiselweyo kwishishini; abanye babo baneengxaki zokungcoliseka kwendalo ukuya kumaqondo ahlukeneyo kwinkqubo yokuvelisa, kwaye basebenzise umgangatho ophantsi , Ixabiso eliphantsi kunye nexabiso eliphantsi eliziswe lutyalo-mali oluphantsi lokhuseleko lokusingqongileyo luye lwachaphazela imarike ye-cellulose ether, okubangele imeko yokhuphiswano olungahambi kakuhle kwimarike. . Emva kokwaziswa kwetekhnoloji entsha kunye neemveliso ezintsha, indlela yokuphelisa intengiso iya kuphucula imeko ekhoyo yokhuphiswano olungalunganga.
(2) Imveliso yobugcisa obuphezulu kunye nexabiso eliphezulu lixhomekeke kulawulo lwangaphandle
Ushishino lwe-cellulose ether lwangaphandle luqale ngaphambili, kwaye amashishini emveliso amelwe yiDow Chemical kunye neHercules Group e-United States akwisikhundla esikhokele ngokupheleleyo ngokwefomula yemveliso kunye nobuchwepheshe. Ithintelwe yithekhinoloji, iinkampani zasekhaya ze-cellulose ether ikakhulu zivelisa iimveliso ezinexabiso eliphantsi kunye neendlela ezilula zenkqubo kunye nokusulungeka kwemveliso ephantsi, ngelixa iinkampani zangaphandle ziye zalawula imarike yeemveliso ze-cellulose ether zexabiso eliphezulu ngokuthatha inzuzo yezobuchwepheshe; ngoko ke, Kwimarike ye-cellulose ether yasekhaya, iimveliso eziphezulu kufuneka zingeniswe ngaphandle kwaye iimveliso eziphantsi zineendlela ezibuthathaka zokuthumela ngaphandle. Nangona amandla okuvelisa kwishishini lasekhaya le-cellulose ether likhule ngokukhawuleza, ukukhuphisana kwayo kwimarike yamazwe ngamazwe kubuthathaka. Ngophuhliso loshishino lwe-cellulose ether, imida yenzuzo yeemveliso eziphantsi kwexabiso elongeziweyo iya kuqhubeka iyancipha, kwaye amashishini asekhaya kufuneka afune impumelelo yezobuchwepheshe ukuze aphule i-monopoly yamashishini angaphandle kwimarike yemveliso ephezulu.
(3) Ukuguquguquka kwamaxabiso ezinto eziphathekayo
Umqhaphu osulungekileyo, eyona nto iphambili ekrwadai-cellulose ether, yimveliso yezolimo. Ngenxa yotshintsho kwindalo esingqongileyo, imveliso kunye nexabiso liya kuguquguquka, nto leyo eya kuzisa ubunzima kulungiselelo lwemathiriyeli ekrwada kunye nolawulo lweendleko zamashishini asezantsi.
Ukongeza, iimveliso zepetrochemical ezifana nepropylene oxide kunye nemethyl chloride zikwabalulekile kwimveliso ye-cellulose ether, kwaye amaxabiso azo achatshazelwa kakhulu kukuguquguquka kwentengiso yeoli ekrwada. Utshintsho kwimeko yezopolitiko yamazwe ngamazwe luhlala lunempembelelo kumaxabiso e-oyile ekrwada, ngoko ke abavelisi be-cellulose ether kufuneka bajongane nemiphumo emibi yokuguquguquka rhoqo kumaxabiso eoli kwimveliso kunye nokusebenza kwabo.
