Uruhare rw'ifu ya latex ishobora gusubirwamo mu bicuruzwa bya morti

1. Ni iyihe mirimo y'ifu ya latex ishobora gusubirwamo muri mortila?

Igisubizo: Ifu ya latex ishobora gukurwamo ikorwa nyuma yo gukwirakwira kandi ikora nk'ubukorikori bwa kabiri kugira ngo yongere ubufatanye; colloid irinda inyurwa na sisitemu ya morti (ntibizavugwa ko yangiritse nyuma yo gukwirakwira. Cyangwa ngo ikwirakwizwe kabiri); polymerization ikozwe Resin isanzwe ikwirakwizwa mu sisitemu yose ya morti nk'ibikoresho bikomeza, bityo byongera ubufatanye bwa morti.

2. Ni iyihe mirimo y'ifu ya latex ishobora gukurwa mu gikoresho gitose?

Igisubizo: Kunoza imikorere y'inyubako; kunoza uburyo amazi anyuramo; kongera imbaraga z'ishushotropi no kurwanya gucika; kunoza uburyo amazi ahurirana; kongera igihe cyo gufungura; kongera uburyo amazi abikwamo;

3. Ni iyihe mirimo y'ifu ya latex ishobora gukurwamo nyuma yo gushya?

Igisubizo: kongera imbaraga zo gukurura; kongera imbaraga zo kunama; kugabanya modulus yoroshye; kongera ubushobozi bwo guhindagurika; kongera ubucucike bw'ibikoresho; kongera ubushobozi bwo kudashira; kongera imbaraga zo gufatana; Ifite ubushobozi bwo kudashira neza mu mazi (hydrophobic) (kongeraho ifu ya rubber yo kudashira mu mazi).

4. Ni iyihe mirimo y'ifu ya latex ishobora gukurwa mu bicuruzwa bitandukanye by'ifu yumye?
