Ntev npaum li qhov tsim nyog ntawm cov zaub mov qib cellulose ether HPMC ntxiv rau cov khoom noj kib, cov roj noj hauv cov txheej txheem kib tuaj yeem txo qis, tag nrho cov roj cov ntsiab lus ntawm cov khoom kib tuaj yeem txo, thiab saj ntawm cov khoom kib. tuaj yeem txhim kho, cov roj hloov lub voj voog ntawm cov khoom noj kib tuaj yeem ua kom ntev, cov txiaj ntsig ntawm cov khoom kib tuaj yeem nce ntxiv thiab cov nqi ntawm cov roj tuaj yeem txo.
Fried zaub mov yog dav hlub los ntawm pej xeem vim nws txawv saj. Txawm li cas los xij, niaj hnub no kev noj qab haus huv ntau ntxiv, cov zaub mov muaj roj ntau kuj ua rau cov neeg siv khoom ceev faj.
Tau kawg, nyob rau hauv daim ntawv thov tshwj xeeb ntawm txhua cellulose ether zaub mov additives tuaj yeem ua tiav ib qho haujlwm, piv txwv li, zaub mov qib methylcellulose (MC) thiab hydroxypropyl methylcellulose (HPMC) tuaj yeem txo cov roj cov ntsiab lus ntawm cov khoom noj kib; Khoom noj khoom haus qib carboxymethyl cellulose (CMC), siv nyob rau hauv cov khoom noj siv mis, tuaj yeem txhim kho qhov saj thiab txhim khu kev ruaj ntseg ntawm cov protein, siv rau hauv cov txheej txheem ci, tuaj yeem tswj cov dej ntsiab lus ntawm khob noom cookie; Khoom noj khoom haus qib hydroxypropyl cellulose (HPC) tuaj yeem txo tus nqi ntawm cov khoom qab zib hauv cov mis, thaum tswj kom du thiab muag, thiab paub txog lub tswv yim ntawm kev noj zaub mov zoo.
Cellulose ether derivatives tau siv dav hauv kev lag luam khoom noj rau lub sijhawm ntev. Kev hloov kho lub cev ntawm cellulose tuaj yeem tswj cov khoom rheological, hydration thiab microstructure zog ntawm lub cev. Lub tsib lub luag haujlwm tseem ceeb ntawm kev hloov kho cellulose hauv cov zaub mov yog rheology, emulsification, ua npuas ncauj ruaj khov, muaj peev xwm tswj cov dej khov siv lead ua thiab kev loj hlob, thiab kev khi dej.
Pab ntau tshaj 20 lub ntiaj teb no cov khoom siv dag zog siv tshuab los ua kev txhawb nqa. Peb cov npe lag luam lag luam feem ntau yog tsom rau Asmeskas thiab European saj. Lub tswv yim yog qhov tseem ceeb rau tus qauv cog tshuaj ntsiav, pab pawg sib koom ua ke. Nyob rau hauv thawj peb lub hlis twg ntawm xyoo tas los, lawv ua ib tug fake version ntawm cov nqaij dag. Peb tab tom sim hloov los ntawm vector ntau lawm hauv chav kuaj. Tam sim no, cov nqaij tawv txawv teb chaws yog 140-150,000 yuan / tuj, tab sis tus nqi kuj tsawg. Lub tuam txhab yuav tau nyiaj ntawm cellulosic ether ua ntej, thiab txhawj xeeb txog cov nyiaj ntawm cov nqaij dag tom qab. Qhov nyuaj tshaj plaws ntawm cov nqaij dag yog cellulose, thiab rau DuPont cellulose ether yog qhov nplaum. Lub tuam txhab muag 70,000 rau 80,000 tons, kuj muaj 60% tag nrho cov paj. Cov cuab yeej tshiab thiab qib siab tshaj plaws, Dow's thiab Shin-etsu cov cuab yeej yog 20 lossis 20 xyoo, yuav los ntawm cov khoom siv hauv lub teb chaws Yelemees. Cov mis mos ntawm cov nqaij dag yog qhov tseem ceeb.
