Nigute ushobora kunoza ukuboko kuremereye kwiyumvamo gushira

ikibazo:

Putty yumva aremereye

Mugihe cyo kubaka putty, abantu bamwe bazahura nikibazo ukuboko kumva kuremereye. Ni izihe mpamvu zihariye? Nigute ishobora kunozwa?

Impamvu zisanzwe zituma putty yumva aremereye ni:

1. Gukoresha nabi moderi ya viscosity ya selile ether:

Muri iki gihe, ubukonje bwa selile ether muri rusange ni hejuru cyane, kandi putty yakozwe izumva iremereye mugihe cyo gusiba;

Indi mpamvu nuko mugihe cyubwubatsi mugihe cyizuba, gukoresha hydroxypropyl methylcellulose ether hamwe nubushyuhe buke bwo hejuru bishobora gutera putty gutakaza ububobere, bizagira ingaruka kumyubakire.

2. Ikigereranyo kibi cyangwa ubwiza bwifu:

Mubisanzwe, hariho ibikoresho byinshi byo gutondeka ibintu bidasanzwe, cyangwa ubwiza bwuzuza bwatoranijwe nibyiza cyane, bikunda kwizirika ku cyuma;

Birashoboka kandi ko kugirango ugabanye ibiciro, nta cyangwa inyongeramusaruro zo kunoza ikiganza cyunvikana, nka etarike ya krahisi na lisansi ya thixotropique.

Inzira zo kunoza 1

Ikigereranyo cyibikoresho bikwiye no guhitamo neza

Ubwiza bwibikoresho rusange birashobora kugenzurwa kuri mesh 150-200, kandi ubwuzuzanye bushobora kuba mesh 325, ntabwo ari byiza cyane;

Ingano ya alcool ya polyvinyl ntishobora kurenza 6%;

Birakenewe kandi kwiga kugabanya ingano yibikoresho bya simaitiki. Mubisanzwe, birahagije kugenzura sima kuri 28% -32%, no gukoresha inyongeramusaruro kugirango utezimbere imikorere yayo.

Uburyo bwo kunoza 2

Hitamo neza selile ya ether

Mubisanzwe, turasaba hydroxyethyl methyl selulose ether hamwe nimikorere myiza, ifite ubushyuhe bwiza bwo hejuru kandi irashobora guhuzwa neza nubwubatsi bwimpeshyi kandi bikagabanya amafaranga yo guhanahana imbeho nimpeshyi;

Urufunguzo nuguhitamo selile ether hamwe na viscosity ikwiye. Mubisanzwe, selile ya selile ifite ubwiza bwa 80.000 kugeza 100.000 irahagije kubifu ya putty, ariko ingano ya selile yongeyeho igomba kugenwa binyuze mubushakashatsi bwubwubatsi bufite ishingiro!

Inzira zo kunoza 3

Ongeraho inyongeramusaruro kugirango utezimbere amaboko

Hanyuma, dushobora gutekereza kongeramo ibinyamisogwe ether cyangwa thixotropic lubricant (bentonite) kugirango tunonosore ibyiyumvo bya minisiteri;

Wibuke: guhuza formulaire ya siyansi nurufunguzo rwo gukemura ikibazo!
