Carboxymethyl cellulose (CMC)ndi polima osungunuka m'madzi opangidwa ndi kusinthidwa kwa mankhwala a cellulose achilengedwe. Amagwiritsidwa ntchito kwambiri muzinthu zamagulu a tsiku ndi tsiku. Monga thickener wamba, stabilizer ndi suspending wothandizira, CMC ali ndi malo ofunika tsiku lililonse mankhwala mankhwala monga mankhwala osamalira khungu, otsukira m`kamwa, zotsukira, etc. ndi katundu wake kwambiri thupi ndi mankhwala.
1. Mankhwala a carboxymethyl cellulose
CMC imapangidwa ndi momwe cellulose yachilengedwe imagwirira ntchito ndi sodium chloroacetate (kapena chloroacetic acid) m'malo amchere. Mapangidwe ake a maselo amaphatikizapo mafupa a cellulose ndi magulu angapo a carboxymethyl (-CH₂-COOH), ndipo kuyambitsidwa kwa maguluwa kumapereka CMC hydrophilicity. Kulemera kwa mamolekyulu ndi kuchuluka kwa kusintha kwa CMC (mwachitsanzo, kuchuluka kwa carboxymethyl m'malo mwa cellulose) ndizomwe zimakhudza kusungunuka kwake ndi kukhuthala kwake. Popanga mankhwala a tsiku ndi tsiku, CMC nthawi zambiri imawoneka ngati ufa woyera kapena wachikasu pang'ono wokhala ndi kusungunuka kwamadzi komanso kukhuthala.
2. Katundu wa carboxymethyl cellulose
Makhalidwe a physicochemical a CMC amapereka ntchito zingapo pazamankhwala atsiku ndi tsiku:
Kukula: CMC imawonetsa kukhuthala mu njira yamadzimadzi, ndipo kukhuthala kwake kumatha kusinthidwa ndi ndende, kulemera kwa maselo ndi kuchuluka kwa m'malo mwa CMC. Kuonjezera CMC muzinthu zamtundu wa tsiku ndi tsiku pamlingo woyenera kumatha kukulitsa kukhuthala kwa chinthucho, kubweretsa chidziwitso cha ogwiritsa ntchito bwino, komanso kulepheretsa malondawo kuti asagwe kapena kutayika.
Stabilizer ndi suspending agents: Gulu la carboxyl mu kapangidwe ka maselo a CMC limatha kupanga zomangira za haidrojeni ndi mamolekyu amadzi ndipo zimakhala ndi kusungunuka kwamadzi komanso kumamatira. CMC imatha kupanga njira yoyimitsidwa yofananira mu yankho, potero imathandizira kukhazikika kwa tinthu tating'onoting'ono kapena madontho amafuta muzogulitsa ndikuletsa mvula kapena kusanja. Katunduyu ndi wofunikira makamaka mu zotsukira ndi zokometsera khungu zopaka utoto zomwe zili ndi zinthu zina.
Katundu wopanga filimu: CMC ili ndi zinthu zabwino kwambiri zopanga filimu, kupanga filimu yoteteza pamwamba pa khungu kapena mano, yomwe ingachepetse kutuluka kwa madzi ndikuwonjezera mphamvu ya mankhwala. Katunduyu amagwiritsidwa ntchito kwambiri pazosamalira khungu komanso zosamalira pakamwa.
Kupaka mafuta: Pazinthu zatsiku ndi tsiku monga mankhwala otsukira mano ndi kumeta thovu, CMC imatha kupereka mafuta onunkhira bwino, kuthandizira kusalala kwazinthu, kuchepetsa kukangana, motero kumathandizira ogwiritsa ntchito.
3. Kugwiritsa ntchito carboxymethyl cellulose pamankhwala atsiku ndi tsiku
Mitundu yosiyanasiyana ya CMC imapangitsa kuti ikhale yofunikira pakupanga mankhwala tsiku lililonse. Zotsatirazi ndizomwe zimagwiritsidwa ntchito pazinthu zosiyanasiyana:
3.1 Otsukira mkamwa
Mankhwala otsukira m'mano ndi chitsanzo cha CMC kugwiritsa ntchito mankhwala tsiku lililonse. CMC amagwiritsidwa ntchito makamaka ngati thickener ndi stabilizer mu otsukira mano. Popeza mankhwala otsukira m`kamwa amafuna kukhuthala zina kuonetsetsa kuyeretsa ogwira ndi chitonthozo pamene potsuka mano, Kuwonjezera CMC kuonjezera mamasukidwe akayendedwe otsukira mano, kotero kuti sadzakhala woonda kwambiri kutsatira mswachi, kapena wandiweyani kwambiri kukhudza extrusion. CMC ingathandizenso kuyimitsa zinthu zina zosasungunuka monga ma abrasives mu mankhwala otsukira mano kuti mawonekedwe a mankhwala otsukira m'mano asasunthike. Komanso, filimu kupanga katundu CMC chimathandiza kupanga wosanjikiza zoteteza pamwamba pa mano, kuonjezera kuyeretsa patsekeke pakamwa.
3.2 Zotsukira
Udindo wa CMC mu zotsukira ndizofunikanso chimodzimodzi. Zotsukira zambiri zamadzimadzi ndi zakumwa zotsuka mbale zimakhala ndi tinthu tating'onoting'ono tomwe timapanga tomwe timapanga tomwe timapanga tomwe timapanga tomwe timapanga tomwe timapanga timapanga tomwe timakhala titasunga. CMC, monga suspending agent ndi thickener, akhoza bwino suspending particles, kukhazikika kapangidwe mankhwala, ndi kupewa stratification. Kuphatikiza apo, CMC imatha kupereka zodzoladzola zina mukamagwiritsa ntchito ndikuchepetsa kupsa mtima kwapakhungu, makamaka mu zotsukira zovala ndi sopo wamanja.
3.3 Zosamalira khungu
Pazinthu zosamalira khungu, CMC imagwiritsidwa ntchito kwambiri ngati thickener ndi moisturizer. Mwachitsanzo, mu zinthu monga mafuta odzola, mafuta odzola ndi zinthu zina, CMC imatha kuonjezera mamasukidwe akayendedwe a zinthuzo ndikubweretsa kumveka bwino kwa ntchito. Mafilimu opanga mafilimu a CMC amathandiza kuti apange filimu yotetezera pakhungu kuti ateteze kuphulika kwa madzi ndikuwonjezera mphamvu yowonongeka ya mankhwala, potero kukwaniritsa cholinga cha nthawi yaitali. Komanso, CMC ali mkulu chitetezo ndi oyenera khungu tcheru ndi mitundu yosiyanasiyana khungu.
3.4 Kumeta thovu ndi zinthu zosamba
Pometa thovu ndi zosamba,CMCamatha kugwira ntchito yopaka mafuta, kuwonjezera kusalala kwa mankhwala, komanso kuchepetsa kugundana kwa khungu. Kukhuthala kwa CMC kumatha kupangitsanso kukhazikika kwa thovu, kupangitsa thovu kukhala lolimba komanso lokhalitsa, kubweretsa kumeta bwino komanso kusamba. Komanso, filimu kupanga katundu CMC akhoza kupanga wosanjikiza zoteteza pakhungu, kuchepetsa kupsa mtima kunja, makamaka oyenera khungu tcheru.
4. Chitetezo ndi kukhazikika kwa carboxymethyl cellulose
CMC imachokera ku cellulose yachilengedwe ndipo imakhala ndi kuwonongeka kwakukulu. Sizidzayambitsa kuipitsa kosalekeza kwa chilengedwe panthawi yogwiritsidwa ntchito, zomwe zimakwaniritsa zofunikira za chitukuko chokhazikika. CMC yatsimikiziridwanso kuti ndiyotetezeka kuti anthu azigwiritsa ntchito. CMC yavomerezedwa ngati chowonjezera cha chakudya m'maiko ambiri, kuwonetsa kuti ili ndi kawopsedwe kochepa m'thupi la munthu. Zomwe zili mu CMC pazamankhwala tsiku lililonse zimakhala zotsika. Pambuyo pa mayesero angapo azachipatala, CMC sidzayambitsa kupsa mtima kwakukulu pakhungu kapena pakamwa, choncho ndiyoyenera kwa anthu amitundu yonse.
Kugwiritsa ntchito kwakukulu kwacarboxymethyl cellulose (CMC)mu mankhwala tsiku ndi tsiku zimatsimikizira ntchito zake zabwino kwambiri komanso kusinthasintha. Monga otetezeka, kothandiza komanso zisathe thickener, suspending wothandizira ndi lubricant, CMC amatenga mbali yofunika zosiyanasiyana tsiku mankhwala mankhwala monga mankhwala osamalira khungu, otsukira mano, detergents, etc. Sizingawongolere zinachitikira mankhwala, komanso kumapangitsanso kukhazikika ndi zotsatira za mankhwala. Kuphatikiza apo, kuchezeka kwa chilengedwe ndi kuwonongeka kwa chilengedwe kwa CMC kumapangitsa kuti ikwaniritse zofuna za anthu masiku ano zopangira zinthu zachilengedwe. Chifukwa chake, momwe ogula amafuna zinthu zapamwamba kwambiri, zotetezeka, komanso zokonda zachilengedwe zikuchulukirachulukira, chiyembekezo chogwiritsa ntchito CMC pamakampani opanga mankhwala tsiku lililonse chidzakhala chokulirapo.
