Cellulose etherndi chilengedwe mapadi (woyenga thonje ndi nkhuni zamkati, etc.) monga zipangizo, pambuyo etherification zosiyanasiyana zotumphukira, ndi mapadi macromolecule hydroxyl haidrojeni ndi etere gulu pang'ono kapena kwathunthu m'malo pambuyo mapangidwe mankhwala, ndi zotumphukira kumtunda kwa mapadi. Ma cellulose amatha kusungunuka m'madzi, kusungunula alkali solution ndi organic zosungunulira pambuyo pa etherification, ndipo amakhala ndi thermoplastic properties. Ma cellulose ether osiyanasiyana, amagwiritsidwa ntchito kwambiri pomanga, simenti, zokutira, mankhwala, chakudya, mafuta, tsiku ndi tsiku mankhwala, nsalu, mapepala ndi zida zamagetsi ndi mafakitale ena. Malinga ndi chiwerengero cha m'malo akhoza kugawidwa mu efa limodzi ndi wosanganiza efa, malinga ionization akhoza kugawidwa mu ayoni mapadi efa ndi sanali ionic mapadi efa. Pakali pano, ionic mapadi etere ionic mankhwala kupanga ndondomeko okhwima, zosavuta kupanga ndi otsika mtengo, zotchinga ndi otsika makampani, makamaka ntchito zina chakudya, zowonjezera nsalu, mankhwala tsiku ndi madera ena, ndi waukulu kupanga mankhwala pa msika.
Pakali pano, padziko lonse lapansi cellulose ether ndiCMC, HPMC, MC, HECndi zina zambiri,CMCzotulutsa ndi zazikulu kwambiri, zomwe zimawerengera pafupifupi theka la zotulutsa zapadziko lonse lapansi, pomwe HPMC ndi MC onse amawerengera pafupifupi 33% ya zomwe zimafunikira padziko lonse lapansi, HEC imakhala pafupifupi 13% ya msika wapadziko lonse lapansi. Kugwiritsa ntchito kofunikira kwambiri kwa carboxymethyl cellulose (CMC) ndi zotsukira, zomwe zimawerengera pafupifupi 22% yazomwe zimafunikira pamsika, ndipo zinthu zina zimagwiritsidwa ntchito kwambiri pomanga, chakudya ndi mankhwala.
Ii. Ntchito yotsika
M'mbuyomu, chifukwa cha kuchepa kwapang'onopang'ono kwa chitukuko cha cellulose ether mumankhwala atsiku ndi tsiku, mankhwala, chakudya, zokutira ndi magawo ena ku China, kufunikira kwa ether ya mapadi ku China kumangokhazikika m'munda wa zida zomangira, mpaka lero, makampani opanga zida zomangira akadali 33% ya kufunika kwa cellulose ether ku China. Ndipo monga China cellulose ether m'munda wa zinthu zomangira zofuna zadzaza, mu mankhwala tsiku ndi tsiku, mankhwala, chakudya, ❖ kuyanika ndi madera ena zofunika ikukula mofulumira ndi chitukuko cha luso ntchito. Mwachitsanzo, m'zaka zaposachedwapa, chomera kapisozi ndi mapadi etere monga chuma chachikulu yaiwisi, komanso akutuluka zinthu zopangidwa nyama yokumba ndi mapadi etere ndi yotakata amafuna chiyembekezo ndi kukula danga.
M'munda wa zipangizo zomangira Mwachitsanzo, mapadi efa ndi thickening, posungira madzi, condensation pang'onopang'ono ndi makhalidwe ena abwino, kotero zomangira kalasi mapadi efa chimagwiritsidwa ntchito bwino ntchito zomangira katundu kuphatikizapo okonzeka-osakaniza matope (kuphatikizapo chonyowa matope osakaniza ndi youma wosanganiza matope), PVC utomoni kupanga, utoto lalabala, kupititsa patsogolo chitukuko cha m'tauni, ndi zina zotero. makampani opanga zida, mulingo wa makina omanga akupitilirabe bwino, ndipo zofunikira za ogula pazomangamanga zikukulirakulira, zomwe zimapangitsa kuti pakhale kufunikira kwa ether yopanda ma ionic cellulose m'munda wa zida zomangira. M'nthawi ya 13th Year Plan Plan, China idafulumizitsa kukonzanso madera owonongeka ndi nyumba zomwe zidawonongeka m'mizinda, ndikulimbikitsa ntchito yomanga nyumba zamatawuni, kuphatikiza kufulumizitsa kukonzanso madera osokonekera ndi midzi m'mizinda, ndikulimbikitsa mwadongosolo kukonzanso kwathunthu madera akale okhala ndi kukonzanso nyumba zakale zosamalizidwa ndi dilapida. Mu theka loyamba la 2021, 755.15 miliyoni masikweya mita okhalamo adakhazikitsidwa, mpaka 5.5 peresenti. Malo omalizidwa a nyumba ndi 364.81 miliyoni masikweya mita, mpaka 25.7%. Kubwereranso kwa malo omalizidwa kugulitsa nyumba kudzayendetsa kufunikira koyenera m'munda wa cellulose ether zomangira.
3. Chitsanzo cha mpikisano wa msika
China ndi dziko lonse mapadi etere kupanga dziko, pa nthawi ino ya zoweta zomangira kalasi mapadi efa kwenikweni akwaniritsa kumasulira, Anxin Chemistry kutsogolera mabizinesi m'munda wa mapadi etere, opanga zina zazikulu m'banja monganso Kima Chemical etc. ❖ kuyanika mlingo, mankhwala chakudya kalasi mapadi efa panopa makamaka United States Dow, Korea Loshinetsu, South Korea, South Korea Loshinetsu, South Korea, South Korea, South Korea. Kuwonjezera Anxin umagwirira angapo matani zikwi khumi mabizinezi, zikwi matani sanali ionic mapadi etero ang'onoang'ono kupanga mabizinezi, ambiri mwa mabizinesi ang'onoang'ono kupanga wamba chitsanzo zipangizo kalasi mapadi efa, ndipo palibe mphamvu kubala kwambiri mkulu-mapeto chakudya ndi mankhwala mankhwala.
Chachinayi, kulowetsa ether ya cellulose ndikutumiza kunja
Mu 2020, chifukwa cha mliri wakunja kwadzetsa kuchepa kwa mabizinesi akunja 'kupanga mphamvu, China cellulose ether kunja anasonyeza chizolowezi kukula mofulumira, mu 2020 kukwaniritsa kunja kwa mapalo ether matani 77,272. Ngakhale kuchuluka kwa katundu wa cellulose ether ku China kumakula mwachangu, zogulitsa kunja zimachokera ku zida zomangira cellulose ether, pomwe kuchuluka kwa ether yamankhwala ndi edible cellulose ether ndi yaying'ono kwambiri, ndipo mtengo wowonjezera wa zinthu zogulitsa kunja ndi wotsika. Pakali pano, kuchuluka kwa ma cellulose ether ku China ndi kuwirikiza kanayi kuchuluka kwa zomwe zimatumizidwa kunja, koma kuchuluka kwa katundu wotumiza kunja sikuposa kawiri kuchuluka kwa zomwe zimatumizidwa kunja. M'munda wa mankhwala apamwamba zoweta mapadi eteri m'malo m'malo ndondomeko akadali lalikulu malo chitukuko.
