Ifu ya latex ishobora kongera gushonga
Ifu ya latex ishobora kongera gushongaItunganywa hakoreshejwe uburyo bwo kumisha bwa emulsion yihariye ya polymer. Ifu ya latex yumye ni uduce duto twa 80 ~ 100mm twakusanyijwe hamwe. Utwo duce dushonga mu mazi kandi tugakora ahantu hanini gato ugereranyije n'uduce twa emulsion twa mbere, dukora agahu nyuma yo kubura amazi no kuma.
Uburyo butandukanye bwo guhindura ibintu butuma ifu ya latex ishobora kongera gushonga igira imiterere itandukanye nko kudakoresha amazi, kudakoresha alkali, kudakoresha ikirere no koroha. Ifu ya latex ikoreshwa muri mortilage ishobora kongera kudakoresha impanuka, kuramba, kudakoresha ubusaza, koroshya ubwubatswe, gukomera no gufatana, kudakoresha ikirere, kudakoresha icyuma gikonjesha, kudakoresha amazi, gukomera no gukomera kw'urukiramende.
Eteri ya selulosi
Cellulose ether ni ijambo rusange risobanura urukurikirane rw'ibicuruzwa bikorwa n'uburyo cellulose ya alkali ikora n'ikintu gitanga ether mu bihe bimwe na bimwe. Alkali cellulose isimburwa n'ibintu bitandukanye bitanga ether kugira ngo haboneke ether zitandukanye za cellulose. Dukurikije imiterere ya ionization y'ibintu bisimbura, ether za cellulose zishobora kugabanywamo ibice bibiri: ionic (nk'icarboxymethyl cellulose) na non-ionic (nk'imethyl cellulose). Dukurikije ubwoko bw'ikintu gisimbura, ether ya cellulose ishobora kugabanywamo monoether (nk'imethyl cellulose) na ether ivanze (nk'ihydroxypropyl methyl cellulose). Dukurikije uburyo butandukanye bwo gushonga, ishobora kugabanywamo ibintu bishonga mu mazi (nk'ihydroxyethyl cellulose) na organic solvent-soluble (nk'ithyl cellulose), nibindi. Mortilla yumye ivanze ahanini ni cellulose ishonga mu mazi, kandi cellulose ishonga mu mazi igabanywamo ubwoko bw'ubwoko bwihuse n'ubwoko bwo gushonga bwatinze kuvurwa.
Uburyo eteri ya selulosi ikora muri mortila ni ubu bukurikira:
(1) Nyuma yaeteri ya seluloseMuri mortiyo ishongeshwa mu mazi, ibintu bitera sima mu buryo bufatika kandi bumwe bikwirakwira neza bitewe n'imikorere y'ubuso, kandi cellulose ether, nk'umuyoboro urinda, "ipfunyika" uduce duto kandi. Urusobe rw'ifiriti itera amavuta rukorwa ku buso bwayo bwo hanze, bigatuma mortiyo ikomera, kandi ikongera ubushyuhe bw'mortiyo mu gihe cyo kuvanga no gukora neza kw'ubwubatsi.
(2) Bitewe n'imiterere ya molekile, umuti wa eteri ya cellulose utuma amazi ari muri mortilage atoroshye gutakaza, kandi ukayarekura buhoro buhoro mu gihe kirekire, bigatuma mortilage ikomeza kubika amazi no gukora neza.
fibre y'ibiti
Fibre y'ibiti ikorwa n'ibimera nk'ibikoresho by'ibanze kandi igatunganywa hakoreshejwe ikoranabuhanga ryinshi, kandi imikorere yayo itandukanye n'iya eteri ya cellulose. Imiterere y'ingenzi ni iyi:
(1) Ntishobora gushonga mu mazi no mu bintu bishongesha, kandi ntishobora gushonga mu bisubizo by'aside idakomeye n'ibisubizo by'ibanze bidakomeye
(2) Iyo ikoreshejwe muri morti, izahurirana mu buryo butatu mu buryo butaziguye, yongera imbaraga za thixotropy no kugwa kw'morti, kandi irusheho kubakwa.
(3) Bitewe n'imiterere y'imigozi y'ibiti ifite imiterere itatu, ifite imiterere yo "gufunga amazi" muri mortilla ivanze, kandi amazi ari muri mortilla ntazoroha kuyinjiza cyangwa kuyikuramo. Ariko ntabwo ifite eteri ya cellulose ifata amazi menshi.
(4) Ingaruka nziza z'imiyoboro y'amazi mu mitsi ifite akazi ko "gutwara amazi" muri morti, bigatuma ubushyuhe bw'imbere n'ubushyuhe bw'imbere muri morti buhora buhindagurika, bityo bigabanye imiyoboro iterwa no kugabanuka gukabije.
(5) Fibre y'ibiti ishobora kugabanya stress yo guhinduka kw'ibumba rikomeye no kugabanya gucika no kwangirika kw'ibumba.
