Imikorere nogukoresha selulose ether mumyiteguro ivanze

Cellulose ether ahanini ifite imirimo itatu ikurikira:
1) Irashobora kubyimba minisiteri nshya kugirango irinde amacakubiri no kubona umubiri umwe wa plastike;
2) Ifite imikorere yo guhumeka ikirere kandi irashobora kandi gutuza uduce duto duto twinjiye muri minisiteri;
3) Nibikoresho bigumana amazi, bifasha kugumya amazi (amazi yubusa) murwego ruto rwa minisiteri, kugirango sima ibone umwanya munini wo kuhira nyuma yo kubaka minisiteri.
Muri minisiteri ivanze yumye, methyl selulose ether igira uruhare mukubungabunga amazi, kubyimba no kunoza imikorere yubwubatsi. Imikorere myiza yo gufata neza amazi iremeza ko minisiteri itazatera umucanga, ifu no kugabanuka kwingufu kubera kubura amazi hamwe na sima ituzuye; Ingaruka yibyibushye yongerera imbaraga imbaraga zububiko bwa minisiteri itose, nkubushobozi bwiza bwo kurwanya igabanuka rya tile; Kwiyongera kwa methyl selulose ether birashobora kugaragara neza kuzamura ubwiza bwamazi ya minisiteri itose, ifite ububobere bwiza kubutaka butandukanye, bityo bikazamura imikorere yurukuta rwa minisiteri itose kandi bikagabanya imyanda.
Iyo ukoresheje ether ya selile, twakagombye kumenya ko niba umubare wa selile ya selile ari mwinshi cyane cyangwa ubukonje bukabije, amazi akenera kwiyongera, kandi kubaka bizagorana (guhomesha) kandi imirimo izagabanuka. Cellulose ether irashobora gutinza igihe cyo gushiraho sima, cyane cyane iyo dosiye ari ndende. Byongeye kandi, selulose ether nayo izagira ingaruka kumwanya wo gufungura, guhindagurika gutembera no gukomera kwa minisiteri.
Ether ikwiye ya selile igomba guhitamo mubicuruzwa bitandukanye, kandi imikorere yayo nayo iratandukanye. Kurugero, MC ifite viscosity yo hejuru igomba gutoranywa muri ceramic tile yometseho, ishobora kongera igihe cyo gufungura nigihe cyo guhinduka, kandi igateza imbere imikorere yo kunyerera; MC ifite ububobere buke bugomba gutoranywa muri minisiteri iringaniza kugirango ibungabunge amazi ya minisiteri, kandi ikagira uruhare mukurinda gusenya no gutandukanya no gufata amazi. Ether ya selile ikwiye kugenwa hakurikijwe ibyifuzo byuwabikoze nibisubizo byikizamini.
Byongeye kandi, selile ya ether ifite ingaruka zifata ifuro, kandi gukora firime hakiri kare bizatera minisiteri. Microstructure ya selulose ether mumashanyarazi mashya avanze kandi akomeye ceramic tile yometseho yakozwe na kaminuza ya Bern hamwe na National National Starch Chemical Company mubusuwisi. Ikizamini cyo mu murima cyerekanwe ku gishushanyo cyerekanye ko selulose ether yahinduye ibibyimba muri minisiteri nshya binyuze mu gukora firime. Izi firime ya selulose ether irashobora kuba yarakozwe mugihe cyangwa nyuma yo gukurura, kandi ifu ya reberse ya reberi itaratangira gukora firime. Ibyingenzi biri inyuma yibi bintu nibikorwa byubuso bwa selile. Nkuko ibibyimba bizanwa na agitator muburyo bwumubiri, selile ether yihuta ifata intera iri hagati yigituba na sima slurry kugirango ikore firime. Izi firime ziracyatose, kuburyo ziroroshye cyane kandi zirashobora guhindagurika, ariko ingaruka ya polarisiyasi yemeza neza gahunda ya molekile zabo. Nyuma, firime ya selile ya selile irashobora kuboneka kumpera ya pore munsi ya scanning electron microscope, nkuko bigaragara ku gishushanyo.
Nka selile ya selulose ni polymer-eruble polymer, izimukira hejuru aho minisiteri ihuza ikirere hamwe no guhumeka kwamazi mumabuye mashya kugirango bibe ubutunzi, bikaviramo uruhu rwa selile ya selile hejuru yubutaka bushya. Nkibisubizo byuruhu, firime isa nubucucike ikorwa hejuru yubutaka, bizagabanya igihe cyo gufungura minisiteri. Niba tile ceramic yometse hejuru yubutaka muri iki gihe, firime nayo izagabanywa imbere yimbere ya minisiteri hamwe nintera iri hagati ya cile ceramic na minisiteri, bityo bigabanye imbaraga zubucuti mugihe cyakurikiyeho. Uruhu rwa selile ya selile irashobora kugabanuka muguhindura formula, guhitamo ether ya selile ikwiye no kongeramo izindi nyongeramusaruro.

Youngcel HPMC / MHEC ikoreshwa cyane nkumukozi wungirije ushinzwe imiti ya Tile Adhesive, Cima Plaster, Kuma ivanze ya minisiteri, Wall putty, Coating, Detergent nibindi.Kandi turashobora kuguha igiciro gito kandi cyiza.

Ibicuruzwa byacu bizwi cyane muri Egiputa, Uburusiya, Afurika y'Epfo, Uburasirazuba bwo hagati, Turukiya, Vietnam, Ubufaransa, Ubutaliyani, Singapore, Bangladesh, Indoneziya, Amerika y'Epfo n'ibindi. Murakoze mbere kandi murakaza neza kubonana.
