01. IRIBURIRO RY'IKIBAZO
Cellulose ni polysaclale polysaclaride igizwe na glucose. SHAKA MU MAZI NA BANZE MU BIKORWA BIKURIKIRA. Nibigize urukuta nyamukuru rw'inkingi z'ibimera, kandi ni na yo yakwirakwijwe cyane kandi cyane muri kamere.
Cellulose ni umutungo mwinshi ku isi, kandi niwowe na polymer karemano hamwe nirubwite nini. Ifite ibyiza byo kuvugururwa, byuzuye bizima, kandi biyongereye.
02. Impamvu zo guhinduranya selile
Ubugari Macronolecules ikubiyemo umubare munini wa -Oh. Bitewe n'ingaruka za hydrogen, imbaraga hagati ya macromolecules ni nini, zizaganisha ku bice binini bishonge △ h; Kurundi ruhande, hariho impeta muri selile macros. Nkimiterere, gukomera k'urunigi rwa molekile ni kinini, bizaganisha ku gushonga bito bihinduka Δ. Izi mpamvu zombi zituma ubushyuhe bwa selile yashongeshejwe (= △ H / △ s) bizahinduka hejuru, kandi ubushyuhe bwa selile ya selile birasa. Kubwibyo, iyo selile yashyutswe kugeza ku bushyuhe runaka, fibre izagaragara kuri selile yagaruwe mbere yuko itangira gushonga, kubwibyo gutunganya ibikoresho bya selile ntibishobora gukosora uburyo bwo gushonga bwa mbere hanyuma ugabumba.
03. Akamaro ko guhinduranya selile
Hamwe no guhagarika buhoro buhoro ibikoresho byamashyamba hamwe nibibazo bikomeye byibidukikije biterwa n'imyanda ya chimique, iterambere no gukoresha ibikoresho bya fibre rusange bishobora kuba bimwe mu bibanza bishyushye abantu bitondera. Cellulose nisoko nini cyane muri kamere. Ifite imitungo myiza nka hygroscopique nziza, antistike, imbaraga zidasanzwe, irangi ryiza, ryiza ryambaye, gutunganya byimazeyo, na biodedadable. Ifite imiterere idahuye na fibre. .
Molekile zirimo umubare munini wamatsinda ya hydroxyl, biroroshye gushiraho amashanyarazi ya hydrogen hamwe namafaranga, kandi yo kubora ubushyuhe butaringaniye. Ariko, selile ifite imihangayiko myiza, kandi isuku yayo irashobora gusenywa nibishushanyo mbonera cyangwa gufatwa, bishobora kugabanya neza ingingo yo gushonga. Nkibicuruzwa bitandukanye byinganda, bikoreshwa cyane mumajwi, gutandukana kwinshi, gutandukanya, plastike, itabi nibikote.
04. Guhinduranya ubugari
Ubutugo bwa Cellulose ni ubwoko bwa selile bakomoka kuri serishisiyo ya selile. Byakoreshejwe cyane kubera ubwinshi bwayo buhebuje, kumarana, guhagarika, gushiraho firime, gukingira Colloid, kugumana ubushuhe, hamwe no gutangaza ibintu. Ikoreshwa mu biryo, ubuvuzi, impapuro zo gukora, gusiga irangi, ibikoresho byo kubaka, nibindi
Guhangana na selile ni urukurikirane rwibibazo bikozwe nimyitwarire ya hydroxyl kumurongo wa selile hamwe nabakozi ba alkylating muburyo bwa alkaline. Kunywa amatsinda ya hydroxyl bigabanya umubare wamazi yimibare kugirango ugabanye imbaraga ziterabwoba, bityo utezimbere imikorere yubushyuhe, kandi icyarimwe ugabanye icyo gishongo cya Cellulose.
Ingero zingaruka zo guhinduranya impinduka kumiterere ya selile:
Gukoresha ipamba itunganijwe nkibikoresho byibanze byibanze, abashakashatsi bakoresheje inzira imwe yo guhinduranya intambwe yo guhindura Carboxymethyl hydroxypropyl hydroxypropyl hydroxyPropyl Gukoresha inzira imwe yo guhinduranya, Carboxymethyl hydroxypropyl selile ifite ubukana bwumunyu, kurwanya acide no kwikeba. Muguhindura umubare ugereranije wa propalene na acide ya chloroacetic, ibicuruzwa hamwe na carboxymethyl na hydroxyPropyl ibirimo birashobora kwitegura. Ibisubizo by'ibizamini byerekana ko Carboxymethyl hydroxypropyl hydroxypropyl yakozwe nuburyo bumwe bwo gukora umusaruro umwe, ibyo kurya byikibazo gito, kandi ibicuruzwa bifite aho birwanya indabyo hamwe na aside nziza.
05. ITEGEKO RY'IBIKORWA BY'UBUTUMWA
Cellulose ni ibintu byingenzi bya shimi hamwe nibikoresho byibikoresho bikungahaye ku mikoro, icyatsi kibisi no mu bidukikije, kandi gishobora kongerwa. Ibikomoka kuri serishisiyo ya selire bifite imikorere myiza, uburyo buhebuje bukoreshwa hamwe ningaruka nziza zo gukoresha neza, kandi ukoreshe ibikenewe mubukungu bwigihugu kuburyo bunini. N'ibikenewe by'iterambere ry'imibereho, hamwe n'iterambere ry'ikoranabuhanga hamwe no gusohoza ibicuruzwa n'ibikoresho by'ibisimba by'ubugari n'ibintu bya sitelique bishobora gukoreshwa n'ingaruka, bizakoreshwa cyane kandi bikamenya ko porogaramu yagutse .
