Isubirwamo rya polymer ifu ya minisiteri

Ifu ya polymer isubirwamo ikunze kugaragara mubwubatsi nkibikoresho byo hanze yinkuta. Igizwe ahanini nuduce twa polystirene nifu ya polymer, bityo yitirirwa umwihariko wayo. Ubu bwoko bwubwubatsi bwa polymer bukorwa cyane cyane kubintu bya polystirene. Ifu ya Mortar polymer ifata neza, imitungo ikora firime, irwanya ikirere hamwe n’imiti ihamye.

Imikorere itandukanye yaminisiterikugarurwapolymerifuigena kandi ko ikoreshwa ryayo ari ryinshi. Ubusanzwe ikoreshwa mubushuhe bwo hanze cyangwa imbere bwimbere yubushyuhe bwo hanze nkurukuta rwo hanze, imbaho ​​za polystirene, hamwe nimbaho ​​zisohoka. Igipfukisho c'ifu ya minisiteri kirashobora kwerekana ibintu byiza biranga amazi, kutirinda umuriro no kubika ubushyuhe.

Ni izihe ntambwe zihariye mu kubaka ifu ya minisiteri na polymer? Reka mvuge muri make kuva ku ngingo 3:

1. Tugomba guhanagura umukungugu kurukuta kugirango tubanze dusukure kandi dufite isuku;

2. Ikigereranyo cyiboneza nuburyo bukurikira powder ifu ya minisiteri: amazi = 1: 0.3, turashobora gukoresha imvange ya minisiteri kugirango tuvange neza mugihe tuvanze;

3.

Kubisobanuro birambuye byubwubatsi, urashobora kureba gusa:

1.Ni uburyo bwibanze bwo kuvura ifu ya minisiteri. Tugomba kwemeza ko ubuso bwibibaho byokwizirika byoroshye kandi bikomeye. Nibiba ngombwa, irashobora gutoneshwa hamwe na sandpaper yuzuye. Muri iki gihe, twakagombye kumenya ko akanama gashinzwe gukingira kagomba gukanda cyane, kandi ibishoboka byose byateganijwe bigomba guhindurwa hejuru yubuso hamwe na polymer yifu ya polystirene;

2. Iyo dushyizeho ifu ya minisiteri, dukeneye kongeramo amazi mu buryo butaziguye, hanyuma tukayungurura iminota 5 mbere yuko ikoreshwa;

3. Kugira ngo hubakwe ifu ya minisiteri, dukeneye gukoresha icyuma kitagira umuyonga kugira ngo tworohereze minisiteri yo kurwanya anti-crack ku kibaho, hanyuma ukande umwenda w'ikirahure fibre mesh mumashanyarazi ashyushye kandi byoroshye. Imyenda ya mesh igomba guhuzwa kandi igapfundikirwa neza. Ubugari bw'igitambara cya fibre fibre ni 10cm, umwenda wa fibre y'ibirahuri ugomba kwinjizwamo byose, kandi ubunini bwa fibre yongerewe imbaraga hejuru ya 2 ~ 5cm.

Ifu ya Mortar polymer nisoko irangiye nyuma yo kongeramo ifu ya polymer. Kurwanya kwayo gukomeye birasa neza, birashobora gukumira neza isuri yumuyaga wa acide hejuru yurukuta, kandi ntabwo byoroshye guhindagurika no gutanga na nyuma yo kuba itose. Kurukuta rwimbere ninyuma.
