Kuyerekeza kwa Methocel ndi Culminal:
Kuti timvetse kusiyana pakati pa Methocel ndi Culminal, tiwona mbali zosiyanasiyana za mankhwala a cellulose ether, kuphatikizapo katundu, ntchito, njira zopangira, ndi zina:
1. Katundu:
Methocel:
- Makalasi a Methocel amatha kusiyanasiyana kukhuthala, kuchuluka kwa kusintha (DS), kukula kwa tinthu, ndi zina. Zosiyanasiyanazi zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito zosiyanasiyana.
- Methocel imadziwika chifukwa chosunga madzi, kukulitsa mphamvu, kukulitsa kumamatira, komanso kupanga mafilimu.
Culminal:
- Maphunziro a Culminal amawonetsanso kusiyana kwa katundu, kuphatikiza kukhuthala, DS, ndi kukula kwa tinthu, kutengera giredi ndi kagwiritsidwe ntchito.
- Culminal cellulose ethers amadziwika chifukwa chosunga madzi, kukulitsa mphamvu, komanso kuwongolera ma rheological mumitundu yosiyanasiyana.
2. Mapulogalamu:
Onse Methocel ndi Culminal amagwiritsidwa ntchito m'mafakitale ndi ntchito zotsatirazi:
- Zomangamanga: Amapeza ntchito m'zomangira, monga zomatira matailosi, matope, ma grouts, ndi zinthu zodzipangira okha, kuti apititse patsogolo zinthu monga kusunga madzi, kugwira ntchito, ndi kumamatira.
- Mankhwala: M'makampani opanga mankhwala, onsewa amagwiritsidwa ntchito ngati omangirira, odzipatula, ndi othandizira otulutsa owongolera pamapangidwe a piritsi ndi machitidwe operekera mankhwala.
- Chakudya: Amagwiritsidwa ntchito m'makampani azakudya kuti akhwime, akhazikike, komanso kukonza kawonekedwe kazakudya, monga sosi, mavalidwe, ndi zinthu zophika buledi.
- Zodzoladzola: Onse Methocel ndi Culminal amagwiritsidwa ntchito muzodzoladzola ndi zinthu zosamalira anthu kuti apereke kukhuthala, mawonekedwe, ndi kukhazikika kwa emulsion.
3. Njira Zopangira:
Njira zopangira Methocel ndi Culminal zimaphatikizapo masitepe ofanana, popeza onse ndi ma cellulose ether. Magawo ofunikira ndi awa:
- Chithandizo cha Alkaline: Gwero la cellulose limayikidwa pamankhwala amchere kuti achotse zonyansa, kutupa ulusi wa cellulose, ndikuwapangitsa kuti athe kupezeka kuti asinthenso mankhwala.
- Etherification: Panthawiyi, maunyolo a cellulose amasinthidwa mwazinthu poyambitsa magulu a hydroxypropyl ndi methyl. Zosinthazi zimakhala ndi udindo pakusungunuka kwamadzi ndi zinthu zina.
- Kutsuka ndi Kusalowerera ndale: Chogulitsacho chimatsukidwa kuti chichotse mankhwala osakhudzidwa ndi zonyansa. Kenako imasinthidwa kuti ikwaniritse pH yomwe mukufuna.
- Kuyeretsa: Njira zoyeretsera, kuphatikiza kusefera ndi kuchapa, zimagwiritsidwa ntchito kuchotsa zonyansa zilizonse zotsala ndi zinthu zina.
- Kuyanika: Ether yoyeretsedwa ya cellulose imawumitsidwa kuti ichepetse chinyezi, ndikupangitsa kuti ikhale yoyenera kukonzedwanso ndikuyika.
- Granulation ndi ma CD: Nthawi zina, zouma mapadi efa akhoza kukumana granulation kukwaniritsa kufunika tinthu kukula ndi otaya makhalidwe. Chomalizacho chimayikidwa kuti chigawidwe.
4. Kupezeka Kwachigawo:
Onse a Methocel ndi Culminal ali ndi kupezeka kwapadziko lonse lapansi, koma kupezeka kwa magiredi enieni ndi malembedwe amatha kusiyanasiyana malinga ndi dera. Otsatsa am'deralo ndi ogulitsa atha kupereka zosankha zosiyanasiyana malinga ndi zomwe dera likufuna.
5. Mayina a Gulu:
Onse a Methocel ndi Culminal amapereka mayina osiyanasiyana amakalasi, iliyonse yopangidwira ntchito kapena mawonekedwe ake. Maphunzirowa amasankhidwa ndi manambala ndi zilembo zomwe zimasonyeza katundu wawo ndi ntchito zomwe akulimbikitsidwa.
Powombetsa mkota,Methocelndi Culminal ndi mankhwala a cellulose ether omwe amagawana ntchito zomwe zimagwiritsidwa ntchito pomanga, mankhwala, chakudya, ndi zodzoladzola. Kusiyana kwakukulu pakati pawo kuli pakupanga, kupangidwa kwazinthu zenizeni, ndi kupezeka kwa madera. Mitundu yonseyi imapereka magiredi osiyanasiyana opangidwira ntchito zosiyanasiyana, iliyonse ili ndi kusiyanasiyana kwamakhalidwe. Posankha pakati pa Methocel ndi Culminal pa pulogalamu inayake, ndikofunikira kukambirana ndi opanga kapena ogulitsa kuti mudziwe chomwe chili choyenera kwambiri ndikupeza zidziwitso zaposachedwa ndi chithandizo chaukadaulo.
