Ibivu birimo ivu rya polymer isubirwamo

Ibivu biva mubisanzweifu ya polymer isubirwamouruganda muri rusange ni 10 ± 2

Ibirimo ivu biri muri 12%, kandi ubwiza nigiciro biragereranywa

Ifu zimwe zo murugo za latx zirenga 30%, ndetse nifu ya reberi ifite ivu rya 50%.

Noneho ubwiza nigiciro cyifu ya polymer itatanye kumasoko ntago ihwanye, gerageza guhitamo

Ibirimo ivu rike, imikorere ihenze hamwe nubwiza buhamye bwo gutanga.

Nigute ushobora guhitamo ifu ya redxersible latex, mubisanzwe ntibishoboka rwose gutangira mugihe ukora formula,

Nta bundi buryo bwiza usibye kubishyira mubicuruzwa byo kugerageza.

Guhitamo ifu ya polymer ikwiranye bikwiye gusuzumwa uhereye kumpande zikurikira:

1. Ubushyuhe bwikirahure cyubushyuhe bwa polymer.

Ubushyuhe bwikirahure ni polymer yerekana elastique;munsi yubushyuhe, polymer yerekana ubugome.

Mubisanzwe, ubushyuhe bwikirahure bwifu ya latex ni -15 ± 5 ℃.

Ahanini ntakibazo.

Ubushyuhe bwinzibacyuho yikirahure nikimenyetso cyingenzi cyerekana imiterere yumubiri wa polymer utatanye, hamwe nibicuruzwa byihariye,

Guhitamo gushyira mu gaciro ubushyuhe bwikirahure bwubushyuhe bwa polymer ifu isubirwamo ifasha kuzamura ibicuruzwa no kwirinda

gucamo, n'ibindi.

2. Ntarengwa ya firime ikora ubushyuhe

Nyuma yisubiramo kandi isubirwamo ifu ya polymer ivanze namazi hanyuma ikongera gusohora, ifite imitungo isa na emulion yumwimerere.

Ni ukuvuga, amazi amaze guhumeka, hazakorwa firime, ifite ihinduka ryinshi kandi ifatanye neza na substrate zitandukanye.

Ubushyuhe buke bwa firime yubushyuhe bwa latex yakozwe nababikora batandukanye bizaba bitandukanye.

Umubare wa bamwe mubakora ni 5 ℃, mugihe cyose ifu ya latex ifite ubuziranenge ifite ubushyuhe bwo gukora firime hagati ya 0 na 5 ℃.

3. Ibintu bidasubirwaho.

Ifu ya polymer idashobora gukwirakwizwa igice cyangwa bigoye gushonga mumazi akonje cyangwa mumazi ya alkaline.

4. Igiciro.

Ibintu bikomeye bigize emulsiyo bigera kuri 53%, bivuze ko toni zigera kuri 1.9 za emulioni zikomera muri toni imwe yifu ya rubber.

Niba ubara amazi 2%, ayo ni toni 1.7 ya emulsiyo yo gukora toni imwe yifu ya reberi, wongeyeho 10% yivu,

Bisaba toni zigera kuri 1.5 za emulion kugirango zitange toni imwe yifu ya rubber.5. Igisubizo cyamazi yifu ya latex

Kugirango ugerageze ubwiza bwifu ya redxersible powder, abakiriya bamwe bashonga gusa ifu ya latex muri

Nyuma yo gukurura amazi, nagerageje kubiganza, nsanga bidafatanye, nuko nibwira ko atari ifu ya latex nyayo.

Mubyukuri, isubirwamo rya porojeri ya latx ubwayo ntabwo ifatanye, ikorwa no gutera spray yumye ya polymerifu.

Iyo ifu ya redispersible polymer ivanze namazi hanyuma ikongera kwigana, iba ifite imiterere imwe na emulion yumwimerere, ni ukuvuga ubushuhe

Filime zakozwe nyuma yo guhumeka ziroroshye guhinduka kandi zifatanije neza na substrate zitandukanye.

Irashobora kandi kongera amazi yibikoresho kandi ikarinda sima ya sima gukomera, gukama no guturika vuba;

Ongera plastike ya minisiteri kandi utezimbere ubwubatsi.Niba igeragezwa rigomba gukorwa, rigomba kuba riringaniye

Kora minisiteri isubiremo kugirango urebe itandukaniro ryayo, imiterere ya firime, guhinduka (harimo ikizamini cyo gukuramo,

Niba imbaraga zumwimerere zujuje ibisabwa) Muri rusange, ibisubizo byubushakashatsi birashobora kuboneka nyuma yiminsi 10
