Cellulose etha ndi chilengedwe mapadi (woyengeka thonje ndi nkhuni zamkati, etc.) monga zopangira, pambuyo etherification zosiyanasiyana zotumphukira, ndi mapadi macromolecule hydroxyl wa hydrogen ndi etere gulu pang'ono kapena kwathunthu m'malo pambuyo mapangidwe mankhwala, ndi zotumphukira kumunsi. wa cellulose.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 ma cellulose ether ndi CMC, HPMC, MC, HEC ndi ena angapo, CMC linanena bungwe lalikulu, mlandu pafupifupi theka la linanena bungwe lonse, pamene HPMC ndi MC onse nkhani pafupifupi 33% ya kufunika padziko lonse, HEC imawerengera 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 madera ena ku China, kufunika kwa cellulose ether ku China kumangokhazikika m'munda wa zomangira, mpaka lero, nyumbayi. Makampani opanga zida akadali 33% yakufunika 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, kasungidwe madzi, condensation pang'onopang'ono ndi makhalidwe ena abwino, kotero zomangira kalasi mapadi efa chimagwiritsidwa ntchito bwino ntchito zomangira mankhwala kuphatikizapo okonzeka osakaniza matope (kuphatikizapo chonyowa). matope osakanikirana ndi matope owuma), kupanga PVC utomoni, utoto wa latex, putty, etc. ndipo zofunikira za chilengedwe za ogula pazomangira zikuchulukirachulukira, zomwe zimapangitsa kuti pakhale kufunikira kwa ether yopanda ma ionic cellulose m'munda wa zida zomangira.Munthawi ya 13th Year Plan Plan, China idafulumizitsa kukonzanso madera akugwa ndi nyumba zowonongeka m'mizinda, komanso kulimbikitsa ntchito yomanga nyumba zamatawuni, kuphatikiza kufulumizitsa kukonzanso madera ndi midzi yomwe ili m'mizinda, komanso kulimbikitsa mwadongosolo kukonzanso kwathunthu malo okhalamo akale ndi kukonzanso nyumba zakale zomwe zidawonongeka ndi nyumba zosakwanira.Mu theka loyamba la 2021, 755.15 miliyoni masikweya mita a malo okhala 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 zikuluzikulu m'banja monganso Kima Chemical etc. ❖ kuyanika mlingo, mankhwala Food grade cellulose ether pakali pano makamaka United States Dow, Ashland, Japan shinetsu, South Korea Lotte ndi monopoly ena akunja.Kuphatikiza paAnxin chemistryangapo oposa zikwi khumi matani mabizinezi, zikwi matani sanali ionic mapadi etero ang'onoang'ono kupanga mabizinezi, ambiri mwa mabizinezi ang'onoang'ono kupanga wamba chitsanzo zomangira kalasi mapadi efa, ndipo palibe mphamvu kubala zambiri 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 m'nyumba mapadi ether m'malo m'malo ndondomeko akadali lalikulu malo chitukuko.
