Kuki selile yitwa polymer?

Cellulose, akunze kwitwa ibintu byinshi bya kama kwisi, ni molekile ishimishije kandi igoye kandi igoye kandi igira ingaruka zikomeye kubintu bitandukanye byubuzima, uhereye kumiterere yibimera no kwipimisha.

Kumva impamvuselileyashyizwe mubyiciro nka polymer, ni ngombwa gucengera mubigize molekale, imiterere yububiko, nimyitwarire yerekana kuri macroscopique na microscopique. Mugusuzuma iyi ngingo, dushobora gufata kamere ya polymer ya selile.

Polymer chimie shingiro:
Ubumenyi bwa Polymer ni ishami rya chimie rivuga ku bushakashatsi bwa macromolecules, ariryo moleki nini igizwe no gusubiramo imitwe izwi nka monomer. Inzira ya polymeration ikubiyemo guhuza aba moko binyuze muri costalet, gukora iminyururu myinshi cyangwa imiyoboro.

Imiterere ya molekilose:
Celecilose igizwe cyane cyane karubone, hydrogen, na atome ya ogisijeni, batunganijwe mumiterere yumurongo. Urugo rwarwo rwibanze, molekile ya glucose, ikora nk'ishami rya monomeric kuri selile polémerizira. Buri gice cya Glucose muri chuline ya selile kijyanye nubundi hakoreshejwe i β (1 →) amatsinda ya glycosic, 1 na karuboni-4 ya glucose ibice bifatika kugirango bibe ihuza.

Igisanzwe cya selile ya selile:

Gusubiramo ibice: β (1 → 4) Guhuza glycosic kuri selile bivamo gusubiramo ibice bya glucose kumunyururu wa polymer. Uku gusubiramo ibice byubaka ni ikintu cyibanze cya polymers.
Uburemere bwo hejuru bwa molekilar: molekile ya selile igizwe na miriyoni ibihumbi nibice bya glucose, biganisha kuri uburemere bunini bwa molekari busanzwe.
Imiterere miremire: Gutegura umurongo wa glucose muminyururu ya glucose muburyo bwagutse iminyururu ya molekile, bin kumurongo uranga urunigi igaragara muri polymers.
Imikoranire yimikorere: molekile ya selile igaragaza ihuza ryiminyururu itera imbere hagati yiminyururu yegeranye, yoroshya gushiraho microfibrils na macroscopique, nka fibre ya selile.
Imitungo: imbaraga za mashini n'imbaraga za selile, ingenzi mu inyangamugayo z'inkike z'ibimera, ziterwa na kamere ya polymer. Iyi mitungo yibutsa ibindi bikoresho bya polymer.
Biodegradabletable: Nubwo yarushijeho gukomera, ubupfura bwa biodegraduamed, burimo guterwa na selile ya glycosidic hagati ya glucose ibice bya glucose, amaherezo bimennye polymer mumahanga yayo.

Gusaba n'akamaro:
Imiterere ya polymer yaselileHindura ibyifuzo byayo bitandukanye mubijyanye n'inganda zitandukanye, harimo impapuro na Pulp, imyenda, imiti, hamwe n'imbaraga zishobora kuvugururwa. Ibikoresho bishingiye kuri selile bihabwa agaciro ubwinshi bwabo, biodegradaditality bitashoboka, no kunyuranya, bigatuma ntahara mubikorwa bya none.

Celekane yujuje ibisabwa nka polymer kubera imiterere yacyo, igizwe no gusubiramo ibice bya glucose bihujwe na β (1 → 4) Gutera iminyururu ndende hamwe nuburemere bwa molekani. Kamere ya Polymer igaragaza mubintu bitandukanye, harimo gushiraho iminyururu yagutse, imikoranire yimikorere, imitungo ya mashini, na biodegrafiya. Gusobanukirwa na selile nkuko polymer ifite ubushishozi bwo gukoresha porogaramu za marriad no gukoresha ubushobozi burambye muburyo burambye nibikoresho.
