Cellulose yomanga imamanga (cellulose ether ether) ndi ma polymer ma polymer omwe amapezeka kudzera mu kusintha kwa mankhwala a cellulose. Amagwiritsidwa ntchito kwambiri ndi zida monga matope, ndi omamatira, ndi kutsata makampani omanga. Cellulose eders amatha kugawidwa m'magulu angapo malinga ndi kapangidwe kake kake ndi katundu. Mitundu wamba imaphatikizaponsoMethyl cellulose ether (MC),hydroxyethyl cellulose ether (hec),Hydroxypropyl methylcellulose (hpmc)ndi zochokera kuzinthu zawo. Ma cellulose awa amakhala ndi katundu wosiyana ndi mankhwala ndipo ndioyenera mapangidwe osiyanasiyana omanga ndi zomwe zimafuna.
1. Methyl cellulose ether (MC)
Methyl cellulose ether ether ether ether solluse ndipo imodzi imodzi mwa cellulose yomanga yomanga. Makhalidwe ake akulu amaphatikizapo:
Kusungunuka:MC imatha kupanga njira yowonekera ya colloidal yotsika m'madzi ozizira.
Kukula:Pomanga matope, MC imatha kuwonjezera mafayilo a yankho ndikusintha kuchuluka kwa matope.
Kusunga kwamadzi:MC ili ndi chisungiko chabwino chamadzi ndipo chimatha kupewa matope kuchokera pakuthana mwachangu panthawi yomanga, potero kutsimikizira ntchito yomanga komanso mphamvu ya pambuyo pake.
Ntchito Zomanga:Zimatha kusintha kubizinesi ya matope ndikuwonjezera nthawi yotseguka, kupangitsa kukhala yabwino kwambiri kugwira ntchito pomanga.
2. Hydroxyethyl cellulose ether (hec)
Hydroxyethyl cellulose ether ndi ethel ethel ether ndi ma hydroxyethyl magulu omwe amayambitsidwa pa cellulose molekyulu. Makhalidwe ake akulu amaphatikizapo:
Kusungunuka:Hec imatha kusungunuka mwachangu m'madzi kuti apange yankho lowonekera.
Kukula:Poyerekeza ndi MC, Hec ali ndi mphamvu yokulirapo ndipo nthawi zambiri imagwiritsidwa ntchito pomanga zida zapamwamba komanso mafayilo.
Kusunga kwamadzi:Hec ali ndi chisungiko chabwino chamadzi ndipo amatha kusunga matonthowo kunyowa kwa nthawi yayitali kuti aletse matope ndi kusweka.
Anti-Kuyimitsidwa:Hec imatha kukonza kuthekera koyimitsidwa kwa tinthu tokhacho kuti tipewe kudontha kapena mpweya.
Anti-Freeze:Hec ali ndi kusintha kwabwino kwa kutentha kochepa ndipo kungagwiritsidwe ntchito m'malo ozizira.
3. Hydroxypropyll Methylcellulose (HPMC)
Hydroxypropyll methylcellulose ndi eleluse yopezedwa ndi gulu la hydroxyl pa molekyulu ya cellulose ndi gulu la hydroxypyl. Makhalidwe ake akulu amaphatikizapo:
Kusungunuka:HPMC imatha kusungunuka mwachangu m'madzi kuti apange cololarent colloid wokhala ndi mafayilo apamwamba.
Kukula ndi kukhazikika:HPMC ili ndi mphamvu yolimba. Akuwonjezera mawonekedwe omanga, imatha kukhalabe ndi kukhazikika kwa matope ndikuchepetsa mpweya wabwino.
Kulimbanso Kwambiri:Poyerekeza ndi a Hec ndi Hec, HPMC ili ndi kulolerana kwambiri ndi kutentha kwambiri, motero ndi koyenera kwambiri pomanga kutentha kwabwino kwambiri.
Kukana kwa Hydrolysis:HPMC ili ndi bata yabwino ya hydrolysis ndipo ndi yoyenera kugwiritsa ntchito zachilengedwe.
4. Katundu wambiri wa celluse et
Kugwiritsa ntchito cellulose kukhala mafakitale omanga kumadalira malo osiyanasiyana, makamaka muzopanga monga matope, zofukizira, ndi zomatira. Otsatirawa ndi ambiri omwe amapezeka kwambiri a cellulose,
Kukula:Cellulose eders moyenera kusintha magwiridwe antchito kapena matope powonjezera ufa wamadzimadzi, ndikukhala ndi madzi abwino komanso kuwunika.
Kusunga kwamadzi:Mu matope a simenti ndi zina zomangira, kusungidwa kwamadzi kwa cellulose kumathandizanso kuchepetsa madzi mwachangu, kumatsimikizira kutsatira nthawi yomanga, ndikupitilira nthawi yomanga opaleshoni.
Kukana kukana:Cellulose ether imatha kukulitsa kuwonongeka kwa zinthu ndikuchepetsa ming'alu yoyambitsidwa ndi kuyanika kapena mphamvu zakunja.
Kutsegulira:Kugwiritsa ntchito ether ether ether kumatha kukonza luso la zomangamanga ndikuwongolera ntchito ya ogwira ntchito.
Anti-Stotmentation:Makamaka m'bwalo lonyowa, ma cellulose ether amatha kuchepetsa kusokonekera kwa zinthu zolimba ndi kusasinthasintha kwa slurry.
5. Ntchito Zogwiritsa Ntchito
Ma cellulo omanga cellulose amagwiritsidwa ntchito makamaka m'magawo otsatirawa:
Matope:Cellulose ether amatha kusintha kusungidwa, kusungidwa kwamadzi, kukana matope ndi matope a matope, ndikugwiritsa ntchito matope, etc.
Utoto:Cellulose ether ingagwiritsidwe ntchito ngati thickener ndikubala utoto kuti musinthe madzi ndikutsatsa utoto.
Zomatira:Kuphatikiza cellulose ether to protemula yomatira imathandizira kuwonjezera mafayilo omatira ndikuwongolera ntchito zomanga.
Matope owuma:Kugwiritsa ntchito matope osakanikirana, kumapereka chisungiko ndi madzi ndikusunga kuti zitsimikizire kuti ndizovuta kupha panthawi yomanga.
Ma cellulose a cellulose ali ndi chiyembekezo chothandiza pantchito yomanga chifukwa cha kuchuluka kwake, kusungidwa kwamadzi, kukana zina ndi zina. Mitundu yosiyanasiyana yacellulose ears(monga mc, hec, hpmc) ali ndi machitidwe ndi ntchito. Kusankha ethel ether koyenera kumatha kukwaniritsa magwiridwe antchito ndi zotsatira zabwino pomanga. Ndi chitukuko chaukadaulo womanga ndi kusintha kwa kufunika, mitundu yosiyanasiyana ya ethel ether nthawi zonse imakulitsa, ndi mitundu yatsopano ya cellose etter etrase imatha kuwonekera mtsogolo.
