Ni izihe gihombo ziterwa na chlorine polyethylene yo mu rwego rwo hasi mu gutunganya PVC

Chlorine polyethylene (CPE) nigicuruzwa cyo guhindura chlorine ya polyethylene yuzuye (HDPE). Nkuguhindura gutunganya PVC, chlorine yibigize CPE igomba kuba hagati ya 35-38%. Bitewe n’ikirere cyiza cyane, kurwanya ubukonje, kurwanya umuriro, kurwanya amavuta, kurwanya ingaruka (CPE ni elastomer), hamwe n’imiti ihamye.

Chlorine polyethylene (CPE) nigicuruzwa cyo guhindura chlorine ya polyethylene yuzuye (HDPE). Nkuguhindura gutunganya PVC, chlorine yibigize CPE igomba kuba hagati ya 35-38%. Bitewe nuko irwanya ikirere cyiza, irwanya ubukonje, irwanya umuriro, irwanya amavuta, irwanya ingaruka (CPE ni elastomer), hamwe n’imiti ihamye, kimwe n’imikoranire myiza na PVC, CPE yabaye impinduka zikoreshwa cyane mu guhindura ibintu muri PVC gutunganya.

1. Iboneza rya molekulari ya HDPE
Bitewe nuburyo butandukanye bwimikorere mugihe cya polymerisation reaction ya PE, hariho itandukaniro muburyo bwimiterere ya molekuline nimiterere ya polymer HDPE. Imiterere ya CPE nyuma ya chlorine ya HDPE hamwe nibintu bitandukanye nabyo biratandukanye. Abakora CPE bagomba guhitamo ibishishwa byihariye bya HDPE kugirango babone umusaruro wa CPE wujuje ibyangombwa.

2. Imiterere ya Chlorination, ni ukuvuga inzira ya chlorine
CPE, nka PVC itunganya modifier, mubisanzwe ikorwa na chlorination reaction ikoresheje uburyo bwo guhagarika amazi ya chlorine. Ibyingenzi byingenzi byiyi nzira ya chlorine ni ingufu zoroheje, dosiye yatangijwe, umuvuduko wibisubizo, ubushyuhe bwibisubizo, igihe cyo kubyitwaramo, hamwe nuburyo bwo kutabogama. Ihame rya PE chlorine iroroshye, ariko uburyo bwa chlorine buragoye.

Bitewe nishoramari rito ugereranije nibikoresho byo gukora CPE, inganda ntoya za CPE zidasanzwe zimaze gukwirakwira mubushinwa. Ibi ntibitera umwanda gusa kubidukikije, ariko kandi nimwe mumpamvu zingenzi zitera ihungabana ryubwiza bwa CPE.

Kugeza ubu, hari umubare munini wa CPE yujuje ubuziranenge ku isoko. Mubisanzwe, hari ubwoko bubiri bwa CPE yo hasi. Imwe imwe iterwa nibihingwa bimwe na bimwe bidafite imiterere ya tekiniki hamwe na chlorine yataye igihe. Ubundi buryo ni ukuvanga urugero runaka rwa calcium karubone cyangwa ifu ya talc muri CPE kugirango ujye mumarushanwa arenganya.
