01.Selirulose ya Hydroxyethyl
Nk'umusemburo utari uwoni, hydroxyethyl cellulose ntabwo ifite gusa inshingano zo guhagarika, gukurura, gutatanya, kuzura, guhuza, gukora filime, kubika amazi no gutanga colloid irinda, ahubwo inagira imiterere ikurikira:
1. HEC ishongeshwa mu mazi ashyushye cyangwa akonje, kandi ntigwa iyo ubushyuhe bwinshi cyangwa ishyushye, ku buryo igira imiterere itandukanye yo gushonga no gushonga, kandi idashyuha cyane;
2. Ugereranyije na selulosi ya methyl izwi na selulosi ya hydroxypropyl methyl, ubushobozi bwo gutatanya bwa HEC ni bwo bubi cyane, ariko koloyide irinda ifite ubushobozi bukomeye cyane.
3. Ubushobozi bwo kubika amazi buri hejuru inshuro ebyiri ugereranyije n’ubwa methyl cellulose, kandi bufite uburyo bwo kugenzura neza amazi.
Amabwiriza yo kwirinda mu gihe ukoresha:
Kubera ko hydroxyethyl cellulose yavuwe ku buso ari ifu cyangwa selulose ikomeye, biroroshye kuyifata no kuyishongesha mu mazi igihe cyose hagaragajwe ibi bikurikira.
1. Mbere na nyuma yo kongeramo hydroxyethyl cellulose, igomba guhora ivangwa kugeza igihe umuti uboneye neza kandi usobanutse.
2. Igomba gushyirwa mu mwobo wo kuvanga buhoro buhoro. Ntugashyiremo selulose ya hydroxyethyl yakozwe mu tubumbe cyangwa utubumbe twinshi mu mwobo wo kuvanga ku bwinshi cyangwa ku buryo butaziguye.
3. Ubushyuhe bw'amazi n'agaciro ka pH by'amazi bifitanye isano rikomeye n'ishonga rya hydroxyethyl cellulose, bityo rero bigomba kwitabwaho cyane.
4. Ntuzigere wongeramo ibintu bimwe na bimwe bya alkaline mu ruvange mbere yukoselulose ya hydroxyethylIfu ishyushywa n'amazi. Kongera agaciro ka PH nyuma yo gushyuha birafasha mu gushonga.
Imikoreshereze ya HEC:
1. Muri rusange ikoreshwa nk'ikintu gikomeza ubushyuhe, ikintu kirinda, kole, ikintu gikomeza ubushyuhe n'inyongera mu gutegura emulsion, gel, amavuta yo kwisiga, amavuta yo kwisiga, ikintu gikuraho amaso, suppository na tableti, ikoreshwa kandi nk'icyuma gifasha mu gushonga kw'amazi, ibikoresho by'amagufwa, gutegura imiti igabanya ubushyuhe mu buryo buhoraho, kandi ishobora no gukoreshwa nk'ikintu gikomeza ubushyuhe mu biribwa.
2. Ikoreshwa nk'umusemburo w'ingano mu nganda z'imyenda, guhuza, gukuba, guhuza, gushimangira no mu bindi bikoresho by'ingirakamaro mu nganda z'ikoranabuhanga n'iz'urumuri.
3. Ikoreshwa nk'imashini igabanya ubushyuhe n'amazi acukura amazi n'amazi arangiza, kandi ifite ingaruka nziza zo gukurura amazi acukura amazi y'umunyu. Ishobora kandi gukoreshwa nk'imashini igenzura igihombo cy'amazi ku sima y'amavuta. Ishobora guhuzwa na iyoni z'icyuma za polyvalent kugira ngo ikore gel.
5. Iki gicuruzwa gikoreshwa nk'ikintu gikwirakwiza amazi gikozwe muri gel, polystyrene na polyvinyl chloride mu gukora amavuta avanze. Gishobora kandi gukoreshwa nk'ikintu gikomeza emulsion mu nganda zikora amarangi, ikintu kirwanya ubushuhe mu nganda zikora ibikoresho by'ikoranabuhanga, ikintu kibuza sima gufungana no kubika amazi mu nganda z'ubwubatsi. Igikoresho cyo gukaranga no kole y'amenyo mu nganda zikora ibumba. Gikoreshwa kandi cyane mu gucapa no gusiga amarangi, imyenda, gukora impapuro, imiti, isuku, ibiryo, itabi, imiti yica udukoko n'ibikoresho bizimya inkongi.
02. Hydroxypropyl Methyl Cellulose
1. Inganda zikora irangi: Nk'umuti ugabanya ubushyuhe, ugabanya ubushyuhe kandi ugabanya ubushyuhe mu nganda zikora irangi, ifite ubushobozi bwo guhuza neza n'amazi cyangwa ibintu bisukura mu buryo bw'umwimerere.
2. Gukora Ceramic: ikoreshwa cyane nk'igikoresho cyo gufunga mu gukora ibikoresho bya Ceramic.
3. Ibindi: Iki gicuruzwa gikoreshwa cyane mu nganda z'impu, mu nganda zikora impapuro, mu kubungabunga imbuto n'imboga no mu nganda zikora imyenda, n'ibindi.
4. Gucapa wino: nk'ikintu gikomeza ubushyuhe, gikwirakwiza ibintu mu nganda za wino, gihura neza n'amazi cyangwa ibintu bidafite ireme.
5. Plasitike: ikoreshwa nk'ikintu gifasha gusohora ibumba, ikintu cyoroshya, amavuta yo kwisiga, n'ibindi.
6. Polyvinyl chloride: Ikoreshwa nk'ikintu gikwirakwiza amashanyarazi mu gukora polyvinyl chloride, kandi ni yo nyunganizi ikomeye mu gutegura PVC hakoreshejwe polimeri yo kuyihagarika.
7. Inganda z'ubwubatsi: Nk'ikintu gifata amazi kandi kigatuma sima ikomeza gukoreshwa, sima ifite ubushobozi bwo kuvoma. Ikoreshwa nk'icyuma gifunga mu gusigwa, gypsum, ifu ya putty cyangwa ibindi bikoresho by'ubwubatsi kugira ngo yongere ubushobozi bwo gukwirakwira no kongera igihe cyo gukora. Ikoreshwa nk'icyuma gifunga amatafari ya ceramic, marble, plastike, nk'icyuma gikomeza gukurura sima, kandi ishobora no kugabanya ingano ya sima. Uburyo hydroxypropyl methylcellulose igumana amaziHPMCbishobora gukumira ko urusenda rucika bitewe no kuma vuba cyane nyuma yo kurukoresha, no kongera imbaraga nyuma yo gukomera.
8. Inganda zikora imiti: ibikoresho byo gusiga; ibikoresho bya firime; ibikoresho bya polymer bigenzura igipimo cyo gutegura ibintu birekura mu buryo buhoraho; ibintu bikomeza guhagarara; ibikoresho bihagarika; ibikoresho bifunga ibinini; ibikoresho byo gufata neza.
Kamere:
1. Ishusho: ifu y'umweru cyangwa iy'umweru.
2. Ingano y'uduce duto; Igipimo cyo gusohora mesh 100 kirenze 98.5%; Igipimo cyo gusohora mesh 80 ni 100%. Ingano y'uduce duto tw'ibipimo byihariye ni mesh 40 ~ 60.
3. Ubushyuhe bwa Carbonation: 280-300℃
4. Ubucucike bugaragara: 0.25-0.70g/cm (ubusanzwe hafi 0.5g/cm), uburemere bwihariye 1.26-1.31.
5. Ubushyuhe bwo guhindura ibara: 190-200℃
6. Ubushyuhe bw'ubuso: 2% by'umuti w'amazi ni 42-56dyn/cm.
7. Gushonga: bishongeshwa mu mazi no mu bintu bimwe na bimwe bishongeshwa, nk'ikigereranyo gikwiye cya ethanol/amazi, propanol/amazi, nibindi. Ibikoresho by'amazi bikoresha ubuso. Gutanga urumuri rwinshi n'imikorere ihamye. Ibikoresho bitandukanye bifite ubushyuhe butandukanye bwa gel, kandi gushonga bihinduka bitewe n'ubushyuhe. Uko ubushyuhe bugabanuka, niko gushonga kuba kunini. Ibikoresho bitandukanye bya HPMC bifite imiterere itandukanye. Gushonga kwa HPMC mu mazi ntibigira ingaruka ku gaciro ka pH.
8. Iyo ingano ya methoxy igabanutse, ingano ya gel iriyongera, ubushobozi bwo gushonga mu mazi buragabanuka, kandi imikorere y'ubuso bwa HPMC iragabanuka.
9. HPMCIfite kandi imiterere yo kugira ubushobozi bwo gukuba, kudakomeza umunyu, ifu y'ivu nke, kudahinduka kwa pH, kubika amazi, kudahinduka kw'ibipimo, imiterere myiza yo gukora filime, hamwe n'uburyo butandukanye bwo kudahinduka kwa enzymes, gukwirakwira no guhuza.
