Ibirimo Ibirimo Ibipimo byo Gusubiramo Polymed Polymer

Imvura ikubiye mu ruganda rusanzwe muri rusange ni 10 ± 2
Ibirimo ivu buri hagati ya 12%, kandi ireme nigiciro biragereranywa
Abakinnyi bamwe batonda murugo barenga 30%, ndetse na powderi zimwe na zimwe za rubber zifite ivu rya 50%.
Ubu ireme nigiciro cyifu ya polymer idahitanye kumasoko iringaniye, gerageza guhitamo
Ibirimo bike, imikorere yigihe kinini hamwe nuburyo buhamye bwo gutanga.
Nigute wahitamo ifu ya latex, muri rusange ntibishoboka rwose gutangira mugihe ukora formula,
Nta nzira nziza usibye kuyishyira mubicuruzwa byo kugerageza.
Guhitamo ifu idahwitse idahima igomba gusuzumwa mubice bikurikira:
1. Ubushyuhe bwinzibacyuho bwikirahure bwifu ya polymer idahakana.
Ubushyuhe bwinzibacyuho ni polymer igaragaza elastique; Munsi yubu bushyuhe, Polymer yerekana ububi.
Mubisanzwe, ubushyuhe bwinzibacyuho yikirahure bwifu ya latex ni -15 ± 5 ℃.
Ahanini ntakibazo.
Ubushyuhe bwinzibacyuho nicyo kimenyetso cyingenzi cyimitungo ya polymer idahakana, hamwe nibicuruzwa byihariye,
Guhitamo neza ubushyuhe bwinzibacyuho yikirahure bwifu ya polymer polymer ifasha kuzamura ibicuruzwa byoroshye no kwirinda
Kumena, nibindi
2. Filime ntarengwa yo gukora ubushyuhe
Nyuma yo kuvugwa kandi byoroshye ifu ya polymer ivanze namazi kandi yongeye kumenyekana, ifite imitungo isa na emulsion yumwimerere.
Ni ukuvuga, Amazi amaze guhinda hejuru, film izashyirwaho, igahinduka cyane kandi nziza yo guhimba substrate zitandukanye.
Ubushyuhe ntarengwa bwa firime bwifu ya latex bwakozwe nababikora batandukanye bizaba bitandukanye.
Ironderero ry'abakora bamwe ni 5 ℃, igihe cyose ifu ya latex ifite ubuziranenge ifite ubushyuhe bwo gukora firime hagati ya 0 na 5 ℃.
3.
Hafi ya polymer idahwitse iratagira igice cyangwa idashidikanywaho mumazi akonje cyangwa amazi ya alkaline.
4. Igiciro.
Ibikubiye muri emulsion ni 53%, bivuze ko hafi toni 1.9 za emulsion zishimangira toni imwe yifu ya rubber.
Niba ubara amazi 2%, ni toni 1.7 zo guhimamara gukora toni imwe ya rubber ifu, wongeyeho 10% yivu,
Bifata toni zigera kuri 1.5 za emulsion kubyara toni imwe ya reberi. 5. Igisubizo gitangaje cya powx ifu
Kugirango ugerageze kuri viscolity yifu ya latex itinze, abakiriya bamwe bashonga gusa ifu ya latex muri
Nyuma yo gukangurira amazi, nagerageje mu ntoki, nsanga bitari byiza, ku buryo natekereje ko atari ifu ya latex.
Mubyukuri, kuvureka ifu ya latex ubwayo ntabwo ifatanye, ikorwa no gukata kwuma emulsion ya polymer
y'ifu.
Iyo ifu ya polymer yongeye kuvanga namazi kandi yongera kugandukira, ifite imitungo nkamagana yumwimerere, ni ukuvuga ubushuhe
Filime zakozwe nyuma yo guhumeka cyane kandi zigakurikiza neza cyane.
Irashobora kandi kongeramo kugumana amazi yibikoresho kandi irinde sirvar mortar ikomera, yumisha kandi ikamena vuba;
Ongera plastike ya minisiteri no kunoza ibikorwa byubwubatsi. Niba igeragezwa rigomba gukorwa, igomba kuba ihwanye
Ese minisiteri ihurira kubona itandukaniro, gushiraho film, guhinduka (harimo no kwipimisha gukururwa,
Niba imbaraga z'umwimerere zujuje ibisabwa) muri rusange, ibisubizo byubushakashatsi birashobora kuboneka nyuma yiminsi 10
