Icyitonderwa: Dushobora guhuza verisiyo iyo ari yo yose ya HTTPB hakurikijwe ibindi bisobanuro by'abakiriya ubusabe.

Kuri HTTPB, EHTPB ni uruhererekane rwa molekile rwa HTPB ruzana amatsinda ya epoxy, afite ibyiza nko kurwanya amavuta, kurwanya gusaza, gukorera mu mucyo mwiza, no gukora neza mu bushyuhe buke. Amatsinda ya hydroxyl ari ku mpera y'uruhererekane rwa molekile n'amatsinda ya hydroxyl mu ruhererekane rwa molekile Itsinda rya epoxy ni itsinda rishobora kuvurwa hakoreshejwe isocyanate zitandukanye n'ibikoresho byo gukangura epoxy. Polymeri yavuwe ifite imiterere myiza ya fiziki na chimique, ifite imbaraga nziza zo gufatana n'ibikoresho bitandukanye bitari ibyuma nk'ibyuma n'ibirahure, imiterere myiza ya dielectric, umuvuduko muto wo gucika, no gukomera. Uburemere buri hejuru, buhamye kugeza kuri alkali n'ubwinshi bw'ibinyabutabire, bushobora kunoza cyane imiterere ya mashini, imbaraga zo gufatana, no kurwanya ubushyuhe bw'ibikoresho bya polyurethane.

EHTTPB ishobora gukoreshwa mu gukora kole, ibifunga, irangi, gukoza resin ya epoxy, elastomer ya polyurethane, nibindi.

Amanota ni aya akurikira:

IGITEKEREZO	EHTTPB-1	EHTTPB-2	EHTTPB-3

* Byongeye kandi: Dushobora gukora ubushakashatsi no guteza imbere verisiyo nshya ya EHTTPB hakurikijwe icyifuzo cyihariye cy'abakiriya bacu.

Kuri ATBN, ATBN ni umusemburo w'amazi wa nitrile ufite amatsinda y'imikorere ya amino ku mpera zombi z'uruhererekane rwa molekile, ushobora kuvurwa hakoreshejwe imiti ivura isocyanate cyangwa ugakorana n'amatsinda ya epoxy kugira ngo ivurwe. ATBN ifite ubushobozi bwo kurwanya amavuta neza, irwanya ubushyuhe, irwanya kwangirika no gufatana neza. Ishobora kugabanya ubushyuhe bwa gel n'ubushyuhe bwo kurwanya epoxy resin iyo ifashe epoxy resin.

ATBN ikoreshwa cyane cyane nk'ikintu gikomeza epoxy resin, ishobora kongera ubukomere bw'ibikoresho bivanze, kongera imbaraga zo gukata no gukata, ndetse ishobora no gukoreshwa nk'ubukorikori butandukanye n'icyuma gifunga.

Ibyiciro bitandukanye bya ATBN ni ibi bikurikira:

IGITEKEREZO	ATBN-1	ATBN-2
Agaciro ka amine, ingano%	0.8 - 1.2	0.8 - 1.2
Ubushyuhe (40℃,Pa.S)	≤10	≤30
Ubushuhe,% ≤	0.05	0.05
Ibipimo bya acrylonitrile, %	10 - 20	22 - 28
Uburemere bwa molekile	2000 - 3000	2000 - 3000
* Byongeye kandi: Dushobora gukora ubushakashatsi no guteza imbere verisiyo nshya ya HTBN dukurikije icyifuzo cyihariye cy'abakiriya bacu.

Kuri HTBNHTBN ni umukara wa nitrile w'amazi ufite amatsinda y'imikorere ya hydroxyl ku mpera zombi z'uruhererekane rw'ibinyabutabire, ufite imiterere imwe n'iya shimi nk'iya nitrile kandi ushobora kuvurwa hakoreshejwe imiti ivura isocyanate, ifite ubushobozi bwo gukora neza no gutunganya. HTBN ifite ubushobozi bwo kurwanya amavuta, kurwanya ubushyuhe, kurwanya kwangirika, kandi ifite imbaraga zikomeye zo gufatana.

HTBN ikoreshwa cyane cyane nk'ikintu gikomeza ibintu bivanze, ibirahure, na resins, ishobora kongera ubukomere, gufatana, kuramba, amavuta n'ubushyuhe by'ibikoresho bivanze.

Verisiyo itandukanye ya HTBN ni iyi ikurikira:

IGITEKEREZO	HTBN-1	HTBN-2

* Byongeye kandi: Dushobora gukora ubushakashatsi no guteza imbere verisiyo nshya ya HTBN dukurikije icyifuzo cyihariye cy'abakiriya bacu.

Kuri CTBN, Butadiene acrylonitrile y’amazi yakuweho karubokisili ni ubwoko bumwe bwa rubber y’amazi ifite itsinda rya carboxyl nk’itsinda ry’imikorere yayo, kandi kode yayo ni CTBN, ishobora gukoreshwa muri rusange mu ndege no mu nganda za gisivili. Ubusanzwe CTBN ikoreshwa hamwe na somatotype resin. CTBN ifite itsinda rikora rya carboxyl ryakuweho karubokisili ishobora gukora kuri epoxy resin kugira ngo yongere ubukana.

Ishobora guhinduranya Hypro 1300x13 CTBN na Hunstman.

hamwe n'imikorere nk'iyi:

1. Yongera ubukomere n'ubushobozi bwo koroshya ubwiza bwa thermoset resins

2. Binoza uburyo bwo gufatana n'ibintu bigoye gufatana na byo

3. Yongera ingaruka no kurwanya imivuniko

4. Yongera uburambe (kurwanya umunaniro)

5. Yongera imiterere y'ubushyuhe buri hasi mu buryo bw'ikoranabuhanga

6. Verisiyo ya FDA irahari
