Nigute ushobora guhitamo ifu ya polymer red

Nigute ushobora guhitamo ifu ya polymer isubirwamo?

Nta bundi buryo bwiza usibye gushyira ibicuruzwa mubigeragezo.

Guhitamo ifu ya redxersible latex igomba gusuzuma ibi bikurikira:

1. Ubushyuhe bwikirahure bwubushyuhe bwa pompe ya polymer.

Ubushyuhe bwikirahure ni uko polymer yerekana elastique; munsi yubushyuhe, polymer yerekana ubugome. Ubushyuhe bwikirahure bwubushyuhe bwa latx rusange ni -15±5℃, na latex ifu yinganda zisanzwe ntizifite iyi ngingo. Ikibazo. Ubushyuhe bwikirahure ni ikimenyetso cyingenzi cyerekana imiterere yumubiri wa redxersible latex. Kubicuruzwa runaka, guhitamo neza ubushyuhe bwikirahure bwikirahure cya redispersible latex ifu ifasha mukuzamura imiterere yibicuruzwa no kwirinda ibibazo nko guturika.

2. Ntarengwa ya firime ikora ubushyuhe

Nyuma yifu ya redxersible latex ivanze namazi hanyuma ikongera gusohora, ifite imiterere isa na emulsiyo yambere, ni ukuvuga ko hazakorwa firime nyuma yuko amazi azimye. Iyi firime ifite ihinduka ryinshi kandi ifatanye neza na substrate zitandukanye. Bitandukanye Ubushyuhe buke bwa firime yubushyuhe bwa latex yakozwe nuwabikoze bizaba bitandukanye. Umubare wa bamwe mubakora ni 0°C, kandi indangagaciro ya bamwe mubakora ni 5°C. Igihe cyose ubushyuhe bwo gukora firime yubushyuhe bwa latex bufite ubuziranenge buri hagati ya 0 na 5°C hagati.

3. Kugabanuka.

Ifu ya redispersible latex ifu igice cyangwa ntigishobora gukemuka mumazi akonje cyangwa mumazi ya alkaline.

4. Igiciro.

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

Niba ibirimo 2% bibaruwe, noneho toni 1.7 za emulsiyo zikoreshwa mugukora toni imwe yifu ya reberi, hiyongereyeho 10% by ivu,

Bisaba toni zigera kuri 1.5 za emulion kugirango zitange toni imwe yifu ya rubber.

5. Igisubizo cyamazi yifu ya latex

Kugirango ugerageze ubwiza bwaifu ya polymer isubirwamo, abakiriya bamwe bashongesheje gusa ifu ya latex mumazi hanyuma bayitera intoki kugirango bayipime, basanga nta gukomera, bibwira ko atari ifu ya latex nyayo.

Mubyukuri, ifu ya redispersible latex ubwayo ntabwo ifatanye, ni ifu yakozwe nyuma ya emulion ya polymer imaze gukama.

Iyo ifu ya redispersible latex ivanze namazi hanyuma ikongera gusohora, iba ifite imiterere imwe na emulion yumwimerere, ni ukuvuga, firime yakozwe nyuma y’amazi amaze guhumeka ifite ihinduka ryinshi kandi ifatanye neza na substrate zitandukanye.

Irashobora kandi kongera amazi yibikoresho, ikarinda sima ya sima gukomera vuba, yumutse kandi igacika; kongera plastike ya minisiteri no kunoza imikorere yubwubatsi. Gutatanya, imiterere ya firime, guhinduka (harimo ikizamini cyo gukuramo, niba imbaraga zumwimerere zujuje ibisabwa) muri rusange, ibisubizo byikizamini bizaboneka nyuma yiminsi 10
