Etarike ya etarike ikoreshwa cyane mubwubatsi bwa minisiteri yubwubatsi, bushobora kugira ingaruka kumurongo wa minisiteri ishingiye kuri gypsumu, sima na lime, kandi igahindura imyubakire hamwe na sag irwanya minisiteri. Ubusanzwe ibinyamisogwe bikoreshwa bifatanije na selile ya selile idahinduwe kandi ihinduwe. Irakwiriye kuri sisitemu zombi zidafite aho zibogamiye na alkaline, kandi irahujwe ninyongeramusaruro nyinshi muri gypsumu nibicuruzwa bya sima (nka surfactants, MC, krahisi na polyvinyl acetate nizindi polymers zishonga amazi).
Ibiranga ibinyamisogwe ether cyane cyane:
(1) Kunoza ubukana bwa sag;
(2) Kunoza kubaka;
(3) Umusaruro mwinshi wa minisiteri.
Ni ubuhe butumwa nyamukuru bwa krahisi ether muri gypsumu ishingiye kuri minisiteri yumye?
Igisubizo: Starike ether nimwe mubintu byingenzi byongerwaho ifu yumye. Irashobora guhuzwa nibindi byongeweho. Ikoreshwa cyane mubikoresho bifata amatafari, gusana za minisiteri, guhomesha gypsumu, imbere no hanze yurukuta rwimbere, gypsum ishingiye kuri caulking hamwe nibikoresho byuzuza, ibikoresho bya interineti, masonry Muri minisiteri, birakwiriye kandi gukoreshwa mumaboko cyangwa gutera imiti hamwe na sima cyangwa gypsumu -ibisasu bya minisiteri. Ikora ku buryo bukurikira:
. Ongeramo urugero rukwiye rwa etarike kuri methyl selulose ether irashobora kunoza cyane kurwanya sag no kurwanya kunyerera kwa minisiteri, hamwe numusaruro mwinshi.
.
.
Ni izihe nyungu zo gusaba hamwe nuburyo bwo kubika krahisi ether?
Igisubizo: Irashobora gukoreshwa nkimvange yibicuruzwa bishingiye kuri sima, ibicuruzwa bishingiye kuri gypsumu nibicuruzwa bya calcium.
(1) Ibyiza nibisabwa:
a. Ifite umubyimba mwinshi kuri minisiteri, irashobora kubyimba vuba, kandi ifite amavuta meza;
b. Igipimo ni gito, kandi dosiye iri hasi cyane irashobora kugera ku ngaruka ndende;
c. Kunoza ubushobozi bwo kurwanya slide ya minisiteri ihujwe;
d. kwagura igihe cyo gufungura ibikoresho;
e. Kunoza imikorere yibikoresho kandi ukore neza.
(2) Ububiko:
Igicuruzwa gishobora kwibasirwa nubushuhe kandi kigomba kubikwa ahantu humye kandi hakonje mubipfunyika byumwimerere. Nibyiza kuyikoresha mugihe cyamezi 12. .
Ni uruhe ruhare rwa methyl selulose ether muri poro yumye?
Igisubizo: Methyl hydroxyethyl selulose ether (MHEC) na methyl hydroxypropyl selulose ether (HPMC) hamwe hamwe bita methyl selulose ether.
Mu rwego rwa poro yumye yumye, methyl selulose ether nigikoresho cyingenzi cyahinduwe kubutaka bwumye nka pompe ya pompe, plaster gypsum, tile yometse, putty, ibikoresho byo kwishyiriraho, spray mortar, wallpaper yometse hamwe nibikoresho bya caulking. Mubutaka butandukanye bwumye, methyl selulose ether ahanini igira uruhare mukubika amazi no kubyimba.
Nubuhe buryo bwo gukora selile ya ether?
Igisubizo: Ubwa mbere, ibikoresho fatizo bya selulose birajanjagurwa, hanyuma bigahinduka kandi bigasunikwa munsi ya soda ya caustic. Ongeramo oxyde olefin (nka okiside ya Ethylene cyangwa propylene oxyde) na methyl chloride ya etherification. Hanyuma, gukaraba amazi no kwezwa birakorwa kugirango ubone ifu yera. Iyi poro, cyane cyane igisubizo cyayo cyamazi, ifite imiterere yumubiri ishimishije. Ether ya selile ikoreshwa mu nganda zubaka ni methyl hydroxyethyl selulose ether cyangwa methyl hydroxypropyl selulose (mu magambo ahinnye yitwa MHEC cyangwa MHPC, cyangwa izina ryoroshye MC). Iki gicuruzwa gifite uruhare runini mubijyanye na poro yumye. uruhare rukomeye.
