Uruhare rwa p-hydroxypropyl krahisi ether muri minisiteri

Etarike ya etarh ni ijambo rusange mubyiciro byahinduwe birimo ibinyamisogwe bya ether muri molekile, bizwi kandi nka etherified krah, ikoreshwa cyane mubuvuzi, ibiryo, imyenda, gukora impapuro, imiti ya buri munsi, peteroli nizindi nganda. Uyu munsi turasobanura cyane cyane uruhare rwa krahisi ether muri minisiteri:

1) Komeza minisiteri, ongera imiti igabanya ubukana, irwanya kugabanuka hamwe na rheologiya ya minisiteri

Kurugero, mukubaka amatafari ya tile, putty, na plaster, cyane cyane ko gutera imashini bisaba amazi menshi, nko muri minisiteri ishingiye kuri gypsumu, ni ngombwa cyane cyane (gypsumu yatewe imashini isaba amazi menshi ariko bizatera kugabanuka gukomeye , ibinyamisogwe Ether irashobora kuzuza iki kibazo). Nukuvuga ko, iyo imbaraga ziva hanze zashyizwe mubikorwa, ibishishwa bigabanuka, bikongerera ubushobozi no gukora pompe, kandi iyo imbaraga zo hanze zavanyweho, ibibyimba byiyongera, bikarwanya ubukana bwo kugabanuka. Kuburyo bugezweho bwo kongera tile agace, kongeramo ibinyamisogwe birashobora kunoza kunyerera kwa tile.

2) Amasaha yagutse yo gufungura

Kumatafari ya tile, irashobora kuba yujuje ibisabwa byamavuta adasanzwe (Icyiciro E, 20min yaguwe kugeza 30min kugirango igere 0.5MPa) yongerera igihe cyo gufungura. Etar ya etar irashobora gutuma ubuso bwa gypsum na sima ya sima byoroha, byoroshye kuyikoresha, kandi bifite ingaruka nziza zo gushushanya. Nibyiza cyane guhomeka minisiteri na thin layer decorator nka putty.

1. Ibinyamisogwe ether irashobora kunoza neza imiti irwanya sag na anti-kunyerera ya minisiteri

Ubusanzwe selulose ether irashobora gusa kunoza ubwiza no kugumana amazi ya sisitemu ariko ntishobora kunoza imitekerereze irwanya kugabanuka no kurwanya kunyerera.

2. Kubyimba no kwiyegeranya

Mubisanzwe, ubwiza bwa selulose ether bugera ku bihumbi mirongo, mugihe ubwiza bwa etarike ya krahisi ari ibihumbi magana kugeza ku bihumbi byinshi, ariko ibi ntibisobanura ko umubyibuho ukabije wa krahisi ya ether kuri minisiteri utameze neza nkuwitwa selulose ether, nuburyo bwo kubyimba byombi biratandukanye.

3. Imikorere yo kurwanya kunyerera

Ugereranije na selile ya selile, etarike ya krahisi irashobora kongera cyane umusaruro wambere wumusaruro wa tile, bityo bikazamura imitekerereze yabyo.

4. Kwinjira mu kirere

Ether ya Cellulose ifite umutungo ukomeye winjiza ikirere, mugihe ether ya krahisi idafite umutungo winjiza ikirere.
