Hydroxypropyl starch ether (HPS)naeteri ya seluloseni inyongeramusaruro ebyiri zikoreshwa mu bwubatsi, zikoreshwa cyane mu bikoresho by'ubwubatsi, nka morti, putty powder, coatings, nibindi. Nubwo bifite aho bihuriye muri bimwe mu bintu, hari itandukaniro rinini mu bintu byinshi nko mu masoko y'ibikoresho fatizo, imiterere ya shimi, imiterere ifatika, ingaruka zo gukoreshwa, n'ikiguzi.
1. Inkomoko y'ibikoresho fatizo n'imiterere yabyo
Hydroxypropyl starch ether (HPS)
HPS ishingiye kuri sitashi karemano kandi iboneka binyuze mu guhindura etherification. Ibikoresho byayo by'ingenzi ni ibigori, ingano, ibirayi n'ibindi bimera karemano. Molekile za sitashi zigizwe n'ibice bya glucose bihujwe n'imigozi ya α-1,4-glycosidic hamwe n'ingano nto ya α-1,6-glycosidic. Nyuma ya hydroxypropylation, itsinda rya hydrophilic hydropropyl ryinjizwa mu miterere ya molekile ya HPS, riyiha imikorere imwe n'imwe yo kubyimba, kubika amazi no kuyahindura.
eteri ya selulose
Eteri za selulosi zikomoka kuri selulosi karemano, nk'ipamba cyangwa ibiti. Selulosi igizwe n'ibice bya glucose bihujwe n'imigozi ya β-1,4-glycosidic. Eteri za selulosi zisanzwe zirimo hydroxypropyl methylcellulose (HPMC), methylcellulose (MC), hydroxyethyl cellulose (HEC), n'ibindi. Ibi binyabutabire byongera ibintu bitandukanye binyuze mu buryo bwo guhindagurika kw'ibintu kandi bifite ubushobozi bwo gukomera no gukomera kw'ibinyabutabire.
2. Imiterere ifatika
Ibiranga imikorere ya HPS
Ububyimbirwe: HPS ifite ubushobozi bwo gukurura ibintu, ariko ugereranyije na eteri ya cellulose, ubushobozi bwayo bwo gukurura ibintu ni buke gato.
Kubika amazi: HPS ifite ubushobozi bwo kubika amazi mu rugero ruciriritse kandi ikwiriye ibikoresho by'ubwubatsi byo mu nyubako zo hasi kugeza hagati.
Gukora neza: HPS ishobora kunoza ubushobozi bwo gukora bwa sima no kugabanya kugwa mu gihe cyo kubaka.
Ubudahangarwa bw'ubushyuhe: HPS ikunda cyane ubushyuhe kandi igirwaho ingaruka cyane n'ubushyuhe bw'ikirere.
Imiterere y'imikorere ya ether za selulose
Ububyimbirwe: Cellulose ether ifite ubushobozi bukomeye bwo gukuba kandi ishobora kongera cyane ubushyuhe bwa morti cyangwa putty.
Kubika amazi: Cellulose ether ifite ubushobozi bwiza bwo kubika amazi, cyane cyane mu bidukikije ubushyuhe bwinshi, ibyo bikaba bishobora kongera igihe cyo gufungura sima no gukumira gutakaza amazi menshi.
Uburyo bwo gukora: Cellulose ether ni nziza cyane mu kunoza uburyo bwo gukora kandi ishobora kugabanya ibibazo nko gucikagurika no gushwanyagurika.
Ubudahangarwa bw'ubushyuhe: Eteri ya selulosi ifite ubushobozi bwo guhangana n'impinduka z'ubushyuhe kandi ikora neza mu buryo buhamye.
3. Ingaruka zo gukoresha
Ingaruka zo gukoreshaHPS
Muri mortila yumye, HPS igira uruhare runini mu kunoza ubushobozi bwo gukora, kunoza uburyo amazi abikwamo, no kugabanya gutandukanya no gutandukanya. Ihendutse kandi ikwiriye gukoreshwa mu bihe bifite ibisabwa byo kugenzura bihendutse, nko mu ifu isanzwe yo mu nzu, mortila yo kugorora hasi, nibindi.
Ingaruka zo gukoresha eteri ya selulose
Eteri za selulosizikoreshwa cyane mu bikoresho byo mu bwoko bwa mortier bikora neza cyane, kole y'amatafari, ibikoresho bishingiye kuri gypsum ndetse na sisitemu zo gukingira inkuta zo hanze. Imiterere yabyo yo gukomera no kubika amazi ishobora kongera imbaraga zo gufatanya no kudacika intege kw'ibikoresho, kandi ikwiriye cyane cyane imishinga ifite ibisabwa byinshi ku mikorere y'ubwubatsi n'ubwiza bw'ibicuruzwa birangizwa.
4. Ikiguzi no kurengera ibidukikije
igiciro:
HPS ifite igiciro gito kandi irakwiriye gukoreshwa ku masoko ashingiye ku biciro. Eteri za selulosi zirahenze cyane, ariko zifite imikorere myiza kandi zihendutse mu mishinga y'ubwubatsi isaba imbaraga nyinshi.
Kurengera ibidukikije:
Byombi bikomoka ku bikoresho karemano kandi bifite imiterere myiza ku bidukikije. Ariko, kubera ko hari ibintu bike bikoreshwa mu gukora HPS, umutwaro wayo ku bidukikije ushobora kuba muto.
5. Ishingiro ry'amahitamo
Ibisabwa mu mikorere: Niba ukeneye ibikoresho byinshi byo gukurura no kubika amazi, ugomba guhitamo eteri ya selulose; ku bikoresho bihendutse ariko bisaba kunoza imikorere, ushobora gutekereza gukoresha HPS.
Uburyo bwo gukoresha: Kubaka ubushyuhe bwinshi, gukingira inkuta inyuma, kole y'amatafari n'ibindi bintu bisaba inkunga ikomeye ni byo bikwiranye cyane na eteri ya cellulose; kuri putty isanzwe yo imbere mu rukuta cyangwa mortier y'ibanze, HPS ishobora gutanga ibisubizo bihendutse kandi bifatika.
Eteri ya Hydroxypropyl starchnaeteri ya selulose Buri kimwe gifite ibyiza byacyo kandi bigira uruhare rutandukanye mu bikoresho by'ubwubatsi. Amahitamo agomba gusuzumwa neza hashingiwe ku bisabwa mu mikorere, igenzura ry'ikiguzi, imiterere y'ubwubatsi n'ibindi bintu by'umushinga runaka kugira ngo haboneke umusaruro mwiza wo gukoresha ibikoresho.
