Monga zinthu zomwe zimagwiritsidwa ntchito kawirikawiri m'mafakitale osiyanasiyana, ma cellulose a m'matumbo ali ndi chidwi chabwino kwambiri, kukula ndi madzi osungidwa. Kugwiritsidwa ntchito kwambiri pomanga, mankhwala, zodzoladzola, chakudya ndi minda ina yambiri. Komabe, kuti mupeze ntchito yabwino kwambiri kuchokera ku cellulose ether, chidwi chiyenera kulipiridwa ku kusungunuka kwake. Nawa zina ndi zina zofunika kuziganizira mukasungunuka cellulose ether:
1. Sankhani zosungunulira zoyenera
Cellulose ether ufa ndi soluble kwambiri m'madzi, ndikupanga njira yowonekera, ma viscous. Komabe, mitundu yosiyanasiyana ya cellose imakhala ndi kusungunuka kosiyanasiyana m'madzi, ndipo kususuka kwawo kumakhudzidwa ndi zinthu monga kutentha ndi Ph. Chifukwa chake, kusankha zosulira zoyenera pankhani yokwanira ndikofunikira.
Mwachitsanzo, ngati cellulose ya ethel iyenera kusungunuka mu malo ocheperako kapena mu PH System, hydroxypllulose (MC) akhoza kukhala bwino kuposa ethylcellulose (EC) kapena carxnse). Ndikofunikira kusankha solformu yoyenera pofufuza zofunikira kugwiritsa ntchito ndi zinthu zosungunulira.
2. Kutentha kwa kutentha
Kutentha ndi chinthu chinanso chofunikira chomwe chikukhudza kusungunuka kwa cellulose ether. Kusungunuka kwa cellose koloko kumawonjezera kutentha, koma chomwechonso kuchuluka kwa kusunthika, komwe kumatha kubweretsa ufa wocheperako kapena wocheperako. Chifukwa chake, kutentha kuyenera kuyang'aniridwa mosamala mu kusungunuka.
Nthawi zambiri, kutentha koyenera kwa kusungunuka cellulose ether ndi 20-40 ° C. Ngati kutentha kumakhala kotsika kwambiri, kungakhale kofunikira kutalikitsa nthawi yophweka kapena kugwiritsa ntchito zosungunulira bwino. Ngati matenthedwe ali okwera kwambiri, amatha kuyambitsa kuwonongeka kwa ethel ether ndipo kumakhudza momwe akugwirira ntchito.
3. Kusambitsa ndikuyambitsa
Kusangalatsa ndi kusokonekera ndikofunikanso pamene kusungunuka kwa cellulose etherder. Kukhazikika koyenera kumathandiza kuti ufa ufalitse kwambiri mu zosungunulira ndikulepheretsa kutseka. Kusunthidwa kumathandizanso kuwonjezera kuchuluka kwa chisinthiko, makamaka mayankho apamwamba a mafayilo.
Komabe, kusokonekera kwambiri kumatha kupanga thovu kapena chithovu, chomwe chingakhudze kumveka komanso kukhazikika kwa yankho. Chifukwa chake, ndikofunikira kusintha liwiro losangalatsa ndi kulimba malinga ndi zofunikira zina ndi malo ogwiritsira ntchito a cellulose ether.
4. Zowonjezera
Zowonjezera zitha kuwonjezeredwa mu kusungunuka kwa cellulose ether ether ether ufa kukonza magwiridwe ake kapena kukhazikika. Mwachitsanzo, borax kapena zinthu zina zamchere zitha kuwonjezeredwa kuti zisinthe PH ya yankho ndikuwonjezera mafayilo. Sodium bicarbonate imawonjezeranso mafayilo a yankho, ndikuchepetsa kuchuluka kwa kusungunuka.
Zina zowonjezera monga zowonjezera, mchere kapena ma polima amatha kugwiritsidwa ntchito kupititsa patsogolo kusungunuka, kukhazikika kapena zinthu zina zama cellulose. Komabe, ndikofunikira kugwiritsa ntchito zowonjezera pang'onopang'ono ndikusankha mosamala, monga zowonjezera kapena zosayenera zitha kuyambitsa zovuta.
5. Kusungunuka nthawi
Nthawi yofananira ndi gawo lofunikira pakupanga ma celluse ether. Nthawi yakufanayo imatengera zinthu zambiri monga mtundu wa cellulose ether ether, zosungunulira, kutentha, liwiro losangalatsa ndi ndende.
Mwambiri, cellulose elwer iyenera kuwonjezeredwa pang'onopang'ono ndipo pang'onopang'ono kusakanikirana mpaka nthawi yothetsera vutoli imapezeka. Nthawi zambiri nthawi zambiri zimatha kukhala zosiyanasiyana mpaka maola angapo, kutengera zinthu zomwe tafotokozazi.
Ndikofunikira kuwunika mosamala njira yosungunulira ndikusintha magawo ngati pakufunika kuonetsetsa kuti ma cellulose a cellulose.
Pomaliza, ma cellulose a elwelose ndi chinthu chosiyanasiyana komanso chofunikira m'gawo lamafakitale. Komabe, kusunthika kosintha ndikofunikira kuti mukwaniritse zoyenera. Pomvera zinthu monga kulolera kusankha, kutentha kutentha, zolimbikitsa, zowonjezera nthawi yayitali, ndizotheka kupeza njira yapamwamba kwambiri yomwe imakwaniritsa zofunikira pa intaneti yomwe imakwaniritsa zofunikira za Pranle.
