Ifu ya putty igizwe ahanini n'ibintu bikora filime (ibikoresho bihuza), ibintu biyungurura, ibintu bifata amazi, ibintu bigabanya ubushyuhe, ibintu bigabanya ubushyuhe, nibindi. Ibikoresho fatizo bisanzwe bya organic mu ifu ya putty birimo: cellulose, starch ya pregelatinized, starch ether, polyvinyl alcohol, ifu ya latex ikwirakwizwa, nibindi. Hasi aha, Polycat izasesengura imikorere n'imikoreshereze y'ibikoresho fatizo bitandukanye bya chemical kuri wewe kimwe kimwe.
Fibre:
Fibre (Amerika: Fibre; Icyongereza: Fibre) bivuga ikintu kigizwe n'udutsi duhoraho cyangwa tudakomeza. Nk'udutsi tw'ibimera, ubwoya bw'inyamaswa, fibre ya silk, fibre ya sintetike, n'ibindi.
Selilulose:
Selulose ni polysaccharide nini igizwe na glucose kandi ni yo gice cy'ingenzi cy'inkuta z'uturemangingo tw'ibimera. Mu bushyuhe bw'icyumba, selulose ntishongera mu mazi cyangwa mu bintu bisanzwe by'umwimerere. Ingano ya selulose iri mu ipamba iri hafi 100%, bigatuma iba isoko karemano ya selulose. Muri rusange, selulose ingana na 40-50%, kandi hari 10-30% ya hemicellulose na 20-30% ya lignin.
Itandukaniro riri hagati ya selulose (iburyo) na sitashi (ibumoso):
Muri rusange, sitashi na selulose byombi ni polysaccharide macromolecular, kandi formula ya molekile ishobora kugaragazwa nka (C6H10O5) n. Uburemere bwa molekile ya selulose ni bunini kuruta ubwa sitashi, kandi selulose ishobora kubora kugira ngo ikore sitashi. Selulose ni D-glucose na β-1,4 glycoside. Polysaccharide macromolecular zigizwe n'imigozi, mu gihe sitashi ikorwa n'imigozi ya α-1,4 glycosidic. Selulose muri rusange ntabwo igizwe n'amashami, ariko sitashi igizwe n'imigozi ya glycosidic 1,6. Selulose ntishonga neza mu mazi, mu gihe sitashi ishongera mu mazi ashyushye. Selulose ntabwo yumva amylase kandi ntihinduka ubururu iyo ihuye na iyode.
Eteri ya selulosi:
Izina ry'Icyongereza ryaeteri ya seluloseni eteri ya selulosi, ikaba ari igikoresho cya polymer gifite imiterere ya eteri ikozwe muri selulosi. Ni umusaruro w'uburyo selulosi (ikimera) ikora hamwe n'ikintu gihindura eteri. Dukurikije imiterere y'ibinyabutabire, ishobora kugabanywamo eteri za anionic, cationic na nonionic. Bitewe n'ikintu gihindura eteri gikoreshwa, hari selulosi ya methyl, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl hydroxyethyl cellulose na phenyl cellulose, nibindi. Mu nganda z'ubwubatsi, eteri ya selulosi nayo yitwa selulosi, izina ridasanzwe, kandi yitwa selulosi (cyangwa ether) neza.
Uburyo bwo gukurura ubunini bwa Cellulose Ether Thickener:
Ibinyabutabire bya eteri ya selulosi ni ibinyabutabire bitari ioni bibyimba ahanini bitewe n'amazi n'imibanire hagati ya molekile.
Uruhererekane rwa polymer rwa eteri ya selulosi biroroshye gukora umugozi wa hydrogen n'amazi mu mazi, kandi umugozi wa hydrogen utuma igira amazi menshi n'imigozi hagati ya molekile.
Ubwoeteri ya seluloseImashini igabanya ubushyuhe yongerwaho irangi rya latex, ifata amazi menshi, bigatuma ingano yayo yaguka cyane, bigabanyiriza umwanya w’amabara, ibyuzuza n’uduce twa latex;
Muri icyo gihe, imiyoboro ya molekile ya eteri ya cellulose irafatanye kugira ngo ikore imiterere y’urusobe rw’ibice bitatu, kandi ibara, ibirungo n’uduce twa latex bikikije hagati mu rusobe kandi ntibishobora gutembera neza.
Muri izi ngaruka ebyiri, ubukana bw'imikorere y'iyi sisitemu burarushaho kwiyongera! Twageze ku bunini twari dukeneye!
