Irangi, risanzwe ryitwa irangi mu Bushinwa. Iryo rangi ryitwa irangi rishyirwa ku buso bw'ikintu kugira ngo kirindwe cyangwa gisharishwe, kandi rishobora gukora agapira gahoraho gafatanye neza n'ikintu kigomba gusigwa.
Hydroxyethyl Cellulose ni iki?
Hydroxyethyl cellulose (HEC), ifite umweru cyangwa umuhondo woroshye, idafite impumuro, idahumanya cyangwa ifu, itegurwa hakoreshejwe uburyo bwo gupima alkaline cellulose na ethylene oxide (cyangwa chlorohydrin), ni iya Nonionic soluble cellulose ethers. Kubera ko HEC ifite ubushobozi bwiza bwo gukurura, guhagarika, gukwirakwiza, gukurura, guhuza, gukora filime, kurinda ubushuhe no gutanga colloid irinda, yakoreshejwe cyane mu gushakisha amavuta, gusiga, kubaka, imiti, ibiribwa, imyenda, gukora impapuro na polymer Polymerization n'ahandi.
Bigenda bite iyo hydroxyethyl cellulose ihuye n'irangi rishingiye ku mazi?
Nk'umusemburo utari uwoni, hydroxyethyl cellulose ifite imiterere ikurikira usibye gukomera, guhagarika, gufatanya, kuremba, gukora filime, gukwirakwiza, kubika amazi no gutanga colloid irinda:
HEC ishongeshwa mu mazi ashyushye cyangwa mu mazi akonje, ubushyuhe bwinshi cyangwa ikaranze nta mvura igwa, ku buryo ifite imiterere itandukanye yo gushonga no gushonga, kandi idashyuha cyane;
Ubushobozi bwo kubika amazi buri hejuru inshuro ebyiri ugereranyije n’ubwa methyl cellulose, kandi bufite uburyo bwo kugenzura neza amazi;
Ugereranyije na methyl cellulose na hydroxypropyl methyl cellulose byemewe, ubushobozi bwo gutatanya bwa HEC ni bwo bubi cyane, ariko ubushobozi bwo kurinda colloid ni bwo bukomeye cyane.
Ntabwo ari ionic kandi ishobora kubana n'izindi polymer nyinshi zishobora gushonga mu mazi, surfactants, n'imyunyu. Ni imashini nziza cyane yo gukurura electrolyte nyinshi;
Nigute wakoresha hydroxyethyl cellulose? Wakongeramo gute?
Ongeraho mu gihe cyo gukora - ubu buryo ni bwo bworoshye kandi bufata igihe gito.
Shyira amazi meza mu ndobo nini ifite icyuma gishyushya cyane. Tangira kuvanga ubudasiba ku muvuduko muto hanyuma ucenge buhoro buhoro hydroxyethyl cellulose mu gikoresho kimwe. Komeza kuvanga kugeza uduce twose twuzuye. Hanyuma ongeramo ibintu bibungabunga n'ibindi bikoresho bitandukanye. Nk'amabara, ibikoresho bigabanya ubushyuhe, amazi ya ammonia, nibindi. Vanga kugeza hydroxyethyl cellulose yose ishongeshejwe burundu (ubushyuhe bw'igikoresho bwiyongera cyane) mbere yo kongeramo ibindi bice muri formula yo gusubiza.
Ifite inzoga z'inkorano
Ni ukubanza gutegura inzoga y'umubyeyi ifite ubunini bwinshi, hanyuma ukayishyira ku gicuruzwa. Akamaro k'ubu buryo ni uko ifite ubworoherane bwinshi kandi ishobora kongerwa ku gicuruzwa cyarangiye, ariko igomba kubikwa neza. Intambwe z'ubu buryo zisa n'intambwe nyinshi mu buryo bwa 1; itandukaniro ni uko nta gikoresho cyo gukamura cyane, kandi hari bimwe mu bikoresho byo gukamura bifite imbaraga zihagije zo kugumana hydroxyethyl cellulose ikwirakwira mu gikoresho kimwe. Bishobora gukomeza gukaraba kugeza bishongeshejwe burundu mu gikoresho cy'umushongi. Ariko, ni ngombwa kumenya ko umuti wo gukamura fungicide ugomba kongerwa ku nzoga y'umubyeyi vuba bishoboka.
Kubera ko hydroxyethyl cellulose ivuwe hejuru ari ifu cyangwa fibre solid, Lihongde ikwibutsa kwita ku ngingo zikurikira mu gihe utegura inzoga ya hydroxyethyl cellulose mother:
(1) Mbere na nyuma yo kongeramo hydroxyethyl cellulose, igomba kuvangwa buri gihe kugeza igihe umuti uboneye neza kandi usobanutse.
(2) Igomba gushyirwa buhoro buhoro mu mvange, kandi ntushyiremo hydroxyethyl cellulose nyinshi cyangwa ngo uyishyire mu mvange.
(3) Ubushyuhe bw'amazi n'agaciro ka PH mu mazi bifitanye isano rikomeye n'ishonga rya hydroxyethyl cellulose, bityo hagomba kwitabwaho by'umwihariko.
(4) Ntugashyiremo ibintu bimwe na bimwe bya alkaline mu ruvange mbere yuko ifu ya hydroxyethyl cellulose itoswa n'amazi. Kongera pH nyuma yo kuvoma bifasha gushonga.
(5) Uko bishoboka kose, ongeramo umuti urwanya udukoko mbere y'igihe
(6) Mu gihe ukoresha hydroxyethyl cellulose ifite ubukana bwinshi, igipimo cy'inzoga y'umubyeyi ntikigomba kurenza 2.5-3% (ukurikije uburemere), bitabaye ibyo inzoga y'umubyeyi izagorana kuyifata.
