Nubuhe buryo bwa selulose ether nk'inyongera ya minisiteri yumye?

Imwe muntandukanyirizo nini hagati ya minisiteri yumye na minisiteri gakondo ni uko minisiteri yumye ihindurwa hamwe n’inyongeramusaruro nkeya. Ongeraho ubwoko bumwe bwinyongera kuri minisiteri yumye byitwa guhinduka kwambere, kongeramo bibiri cyangwa byinshi byongeweho ni uguhindura kabiri. Ubwiza bwa minisiteri yumye biterwa no guhitamo neza ibice no guhuza no guhuza ibice bitandukanye. Ibikoresho byongera imiti bihenze kandi bigira ingaruka zikomeye kumiterere ya minisiteri yumye. Kubwibyo, muguhitamo inyongeramusaruro, ingano yinyongera igomba kuba kumwanya wambere. Ibikurikira nintangiriro ngufi yo guhitamo imiti yongera imiti ya selile ether.

Cellulose ether izwi kandi nka rheologiya ihindura ubwoko bwimvange ikoreshwa muguhindura imiterere ya rheologiya ya minisiteri mishya ivanze, hafi ikoreshwa muburyo bwose bwa minisiteri. Imitungo ikurikira igomba kwitabwaho muguhitamo ubwoko n'amafaranga yongeweho:

(1) Kubika amazi ku bushyuhe butandukanye;

(2) kubyimba, kwiyegeranya;

(3) Isano iri hagati yubushyuhe nubushyuhe, ningaruka zo guhora imbere ya electrolyte;

(4) imiterere n'urwego rwa etherification;

.

(6) Igipimo cyo gusenyuka, imiterere no gusesa byuzuye.

Usibye kongeramo selile ether muri minisiteri yumye (nka methyl selileulose ether), irashobora kandi kongeramo ester acide vinyl polyvinyl, ni ukuvuga guhindura kabiri. Ihuza rya organic organique muri minisiteri (sima, gypsumu) irashobora kwemeza imbaraga zo gukomeretsa cyane, ariko ntigira ingaruka nke kumbaraga zinguvu no gukomera. Vinyl polyvinyl ester yubaka firime ya elastike mu mwobo wamabuye ya sima, gukora minisiteri irashobora kwikorera imitwaro myinshi yo guhindura ibintu, kunoza imyambarire. Byagaragaye mu myitozo ko mu kongeramo urugero rutandukanye rwa methyl selulose ether na vinyl polyvinyl ester muri minisiteri yumye, isahani yoroheje yometseho plaque ihuza minisiteri, pompe ya pompe, minisiteri yo gushushanya, minisiteri ya beto yubatswe na minisiteri yo kwisuka hasi. irashobora gutegurwa. Kuvanga byombi ntibishobora kuzamura ubwiza bwa minisiteri gusa, ahubwo binanoza cyane imikorere yubwubatsi.

Mubikorwa bifatika, kugirango tunoze imikorere yuzuye, birakenewe gukoresha imvange nyinshi. Ihuza ryiza hagati yinyongeramusaruro, igipimo gikwiye cya dosiye, igereranyo, irashobora kuva mubice bitandukanye bigira ingaruka zimwe na zimwe zo kunoza imikorere ya minisiteri, ariko ingaruka zayo zo guhindura za minisiteri iyo zikoreshejwe zonyine ni nke, rimwe na rimwe zikagira n'ingaruka mbi, nkizo nka fibre imwe ya dope, mukwongerera imbaraga za minisiteri, gabanya urwego rwa stratifike icyarimwe, Nyamara, gukoresha amazi ya minisiteri byiyongera cyane kandi bibikwa mubitaka, ibyo bigatuma imbaraga zo kwikuramo zigabanuka. Iyo hiyongereyeho umwuka winjiza ikirere, urugero rwa minisiteri yo gukuraho no gukoresha amazi birashobora kugabanuka cyane, ariko imbaraga zo kwikuramo za minisiteri zizagabanuka kubera byinshi. Kunoza imyubakire ya masonry kugirango ikorwe neza, mugihe wirinze kwangiriza undi mutungo, imbaraga za minisiteri yububiko bwa minisiteri, urwego rwa stratifike kandi wujuje ibyangombwa bya injeniyeri n'amabwiriza agenga tekinike, icyarimwe, ntukoreshe lime putty, uzigama sima. , kurengera ibidukikije, nibindi, uhereye kugabanya amazi, ubukonje, kubyimba amazi hamwe no guhumeka ikirere, Birakenewe gufata ingamba zuzuye zo guteza imbere no gukoresha imvange.
