- Ibicuruzwa byihariye: Methocel itanga amanota atandukanye afite imitungo nibisabwa bitandukanye, harimo Methocel CRT yo kubaka na Methocel MW ya farumasi.
- Ibyingenzi byingenzi: amanota ya Methocel arashobora kwerekana itandukaniro mubyiza, urwego rwo gusimbuza (DS), nibindi bintu.Bazwiho kubika amazi, ubushobozi bwo kubyimba, hamwe no gukora firime.
- Kubaho kwisi yose: Methocel nikirangantego kizwi cyane cya selile ether hamwe nisi yose, iboneka mukarere kinyuranye.
2. Culminal:
- Ihinguriro: Culminal nizina ryirango rya selile ya selile yakozwe na Ashland, uruganda rukora imiti mpuzamahanga.Ashland kabuhariwe mubisubizo bitandukanye byimiti nibicuruzwa.
- Gusaba: Culminal selulose ethers ikoreshwa mubwubatsi, imiti, ibiryo, no kwisiga, bisa na Methocel.Bakora inshingano nkibinini, binders, stabilisateur, nibindi byinshi.
- Ibicuruzwa byihariye: Culminal itanga urutonde rwibicuruzwa bya selulose ether igenewe porogaramu zihariye.Impamyabumenyi nka Culminal C na Culminal M zikoreshwa cyane mubwubatsi na farumasi.
- Ibyingenzi byingenzi: amanota ya Culminal yerekana itandukaniro mubyiza, ingano yingingo, na DS, bitewe nibisabwa.Bazwiho kubika amazi, ubushobozi bwo kubyimba, no kugenzura imvugo.
- Kubaho kwisi yose: Culminal nikirangantego kizwi hamwe nisi yose, kiboneka mubice bitandukanye.
Kugereranya Methocel na Culminal:
Kugira ngo dusobanukirwe itandukaniro riri hagati ya Methocel na Culminal, tuzasesengura ibintu bitandukanye byibyo bicuruzwa bya selile ya selile, harimo imitungo, porogaramu, inzira yumusaruro, nibindi byinshi:
1. Ibyiza:
Methocel:
- amanota ya Methocel arashobora gutandukana mubwiza, urwego rwo gusimbuza (DS), ingano yingingo, nibindi bintu.Ihindagurika rituma bikwiranye na porogaramu zitandukanye.
- Methocel izwiho kubika amazi, ubushobozi bwo kubyimba, kongera imbaraga, hamwe no gukora firime.
Culminal:
- Indangamanota ya Culminal nayo yerekana itandukaniro mumitungo, harimo viscosity, DS, nubunini buke, bitewe nurwego rwihariye na progaramu.
- Culminal selulose ethers izwiho kubika amazi, ubushobozi bwo kubyimba, no kugenzura rheologiya muburyo butandukanye.
2. Gusaba:
Methocel na Culminal byombi bikoreshwa mubikorwa bikurikira:
- Ubwubatsi: Basanga gukoreshwa mubikoresho byubwubatsi, nkibikoresho bifata tile, minisiteri, grout, hamwe n’ibikoresho byo kwishyira hamwe, kugirango bongere imitungo nko kubika amazi, gukora, no gufatira hamwe.
- Imiti ya farumasi: Mu nganda zimiti, zombi zikoreshwa nka binders, disintegrants, hamwe nubugenzuzi-burekura mugukoresha ibinini no gutanga imiti.
- Ibiribwa: Bikoreshwa mu nganda zibiribwa kugirango babyibushye, bihamye, kandi bitezimbere ubwiza bwibicuruzwa byibiribwa, nk'amasosi, imyambarire, n'ibicuruzwa bitekera imigati.
- Amavuta yo kwisiga: Methocel na Culminal byombi bikoreshwa mumavuta yo kwisiga hamwe nibicuruzwa byita kumuntu kugirango bitange ubwiza, ubwiza, hamwe na emulsiyo itajegajega.
3. Uburyo bwo gukora:
Ibikorwa byo kubyaza umusaruro Methocel na Culminal birimo intambwe zisa, kuko zombi ari selile.Ibyiciro by'ingenzi birimo:
- Umuti wa alkaline: Inkomoko ya selile ikorerwa alkaline kugirango ikureho umwanda, kubyimba fibre selile, kandi itume bishoboka kugirango hahindurwe imiti.
- Etherification: Muri iki cyiciro, iminyururu ya selile ihindurwa muburyo bwo gutangiza hydroxypropyl na methyl.Ihinduka rishinzwe gushonga amazi nibindi bintu.
- Gukaraba no kutabogama: Igicuruzwa cyogejwe kugirango gikureho imiti idakorewe hamwe n’umwanda.Hanyuma irabogamye kugirango igere kurwego rwa pH rwifuzwa.
- Isuku: Inzira yo kweza, harimo kuyungurura no gukaraba, ikoreshwa kugirango ikureho umwanda wose usigaye hamwe n’ibicuruzwa.
- Kuma: Ether ya selile isukuye yumye kugirango igabanye ubuhehere bwayo, bigatuma ikomeza gutunganywa no gupakira.
- Gukwirakwiza no gupakira: Rimwe na rimwe, ether yumye ya selile yumye irashobora gukorerwa granulation kugirango igere ku bunini bwifuzwa no kuranga ibintu.Ibicuruzwa byanyuma birapakirwa kugirango bikwirakwizwe.
4. Kuboneka mu karere:
Methocel na Culminal byombi bifite isi yose, ariko kuboneka amanota yihariye hamwe nibisobanuro birashobora gutandukana mukarere.Abatanga ibicuruzwa n'ababitanga barashobora gutanga ibicuruzwa bitandukanye bishingiye kubisabwa mukarere.
5. Amazina y'Icyiciro:
Methocel na Culminal byombi bitanga amazina atandukanye yo murwego, buri kimwe cyagenewe porogaramu yihariye cyangwa ibiranga.Aya manota yagenwe numubare ninyuguti byerekana imiterere yabyo hamwe nibisabwa gukoreshwa.
Muri make,Methocelna Culminal nibicuruzwa bya selulose bisangiye ibintu bisanzwe mubwubatsi, imiti, ibiryo, no kwisiga.Itandukaniro ryibanze hagati yabo riri mubakora, ibicuruzwa byihariye, hamwe no kuboneka kwakarere.Ibirango byombi bitanga urutonde rwamanota agenewe porogaramu zitandukanye, buri kimwe gifite itandukaniro mumiterere.Iyo uhisemo hagati ya Methocel na Culminal kubisabwa byihariye, ni ngombwa kugisha inama ababikora cyangwa abatanga isoko kugirango bamenye ibicuruzwa bibereye kandi babone amakuru y'ibicuruzwa bigezweho hamwe n'inkunga ya tekiniki.
