Ndezvipi zvinotsanangurwa zve fiber, cellulose, uye cellulose ether uye ndeapi musiyano uripo?

Upfu hweputty hunonyanya kuumbwa nezvinhu zvinogadzira firimu (zvinhu zvinobatanidza), zvinozadza, zvinochengetedza mvura, zvinosimbisa, zvinobvisa mafungu, nezvimwewo. Zvinhu zvakajairika zvemakemikari eorganic muupfu hweputty zvinosanganisira: cellulose, starch yakagayiwa, starch ether, polyvinyl alcohol, dispersible latex powder, nezvimwewo. Pasi apa, Polycat ichaongorora mashandiro uye mashandisirwo emhando dzakasiyana dzemakemikari kwauri chimwe nechimwe.

Faibha:

Fiber (US: Fiber; Chirungu: Fiber) zvinoreva chinhu chinoumbwa neshinda dzinoramba dzichienderera mberi kana dzisingaenderere mberi. Dzakadai seshinda dzezvirimwa, bvudzi remhuka, shinda yesirika, shinda dzekugadzira, nezvimwewo.

Serosi:

Cellulose ipolysaccharide yakakura inoumbwa neglucose uye ndiyo inonyanya kukosha mumadziro emasero emiti. Pakupisa kwemumba, cellulose hainyungudike mumvura kana mune zvinonyungudutsa zvakasikwa. Kuwanda kwe cellulose mudonje kuri pedyo ne100%, zvichiita kuti ive sosi chaiyo ye cellulose. Kazhinji, cellulose inokwana 40-50%, uye kune 10-30% hemicellulose uye 20-30% lignin.

Musiyano uripo pakati pe cellulose (kurudyi) nestarch (kuruboshwe):

Kazhinji, starch ne cellulose zvese zviri macromolecular polysaccharides, uye fomura yemamorekuru inogona kuratidzwa se (C6H10O5) n. Kurema kwemamorekuru e cellulose kwakakura kupfuura kwestarch, uye cellulose inogona kuodzwa kuti ibudise starch. Cellulose iD-glucose uye β-1,4 glycoside Macromolecular polysaccharides inoumbwa nemabond, nepo starch ichiumbwa nema α-1,4 glycosidic bonds. Cellulose kazhinji haina matavi, asi starch inoumbwa nema 1,6 glycosidic bonds. Cellulose hainyungudike zvakanaka mumvura, nepo starch ichinyungudika mumvura inopisa. Cellulose haina hanya ne amylase uye haishanduki bhuruu kana yaiswa kune iodine.

Cellulose Ether:

Zita rechiRungu rekutiether ye cellulosei cellulose ether, inova polymer compound ine ether structure yakagadzirwa ne cellulose. Ndiyo chibereko che chemical reaction ye cellulose (chirimwa) ine etherification agent. Zvichienderana ne chemical structure classification ye substituent mushure me etherification, inogona kukamurwa kuita anionic, cationic uye nonionic ethers. Zvichienderana ne etherification agent inoshandiswa, kune methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose, cyanoethyl cellulose, benzyl cyanoethyl cellulose, carboxymethyl hydroxyethyl cellulose uye phenyl cellulose, nezvimwewo. Muindasitiri yekuvaka, cellulose ether inonziwo cellulose, iro zita risingawanzoitiki, uye inonzi cellulose (kana ether) nemazvo.

Maitiro Ekukora kweCellulose Ether Thickener:

Cellulose ether thickeners imhando dzenon-ionic thickeners dzinonyanya kukoira nekuda kwemvura uye kusangana pakati pemamorekuru.

Cheni yepolymer ye cellulose ether iri nyore kugadzira chisungo chehydrogen nemvura mumvura, uye chisungo chehydrogen chinoita kuti ive nemvura yakawanda uye inobatanidza mamorekuru.

Kanaether ye celluloseChinogocha chinowedzerwa papendi yelatex, chinotora mvura yakawanda, zvichiita kuti huwandu hwayo huwedzere zvakanyanya, zvichideredza nzvimbo yakasununguka yepigments, fillers uye latex particles;

Panguva imwe chete, macheni e-cellulose ether akabatana kuti aumbe chimiro chenetwork chine mativi matatu, uye pigments, fillers uye latex particles zvakakomberedzwa pakati pemesh uye hazvigone kuyerera zvakasununguka.

Pasi pemigumisiro miviri iyi, viscosity yesystem inovandudzwa! Tawana simba rekukora rataida!
