Kamangidwe kake:

short


Mankhwala Mwatsatanetsatane

Zogulitsa

Chizindikiro chazikhalidwe:

Powala wachikaso wonyezimira kapena wachikasu

Zamkatimu ≥ 98%

Malo osungunuka ≥ 154 ℃

Kutentha kwakanthawi ≤ 0.3%

Phulusa ≤ 0.3%

Malangizo:

BMI, ngati masanjidwe abwino a utomoni wopangira zida zosagwiritsa ntchito kutentha ndi kalasi H kapena F zida zotsekera zamagetsi, imagwiritsidwa ntchito kwambiri pakupanga ndege, mlengalenga, mphamvu yamagetsi, zamagetsi, makompyuta, kulumikizana, sitima, njanji, zomangamanga ndi mafakitale ena . Zimaphatikizapo:

1. Penti yotentha kwambiri yopatsa phula (zosungunulira zosungunulira ndi zosungunulira), utoto wopangidwa ndi waya, laminate, tepi yaulere, tepi ya mica, zokutira zamkuwa zamagetsi, pulasitiki wopangidwa, epoxy osinthidwa F ~ H coating kuyanika kwa ufa, magawo oponyera, ndi zina zambiri .; 2. MwaukadauloZida gulu masanjidwewo utomoni, Azamlengalenga, ndege structural zipangizo, mpweya CHIKWANGWANI mkulu kutentha zosagwira mbali structural mbali, mkulu amasankha kusindikizidwa bolodi dera ndi zipangizo zina zinchito, etc;

3.Kulimbikitsanso kusintha kosinthana, kulumikizana ndi othandizira komanso othandizira othandizira mphira m'mapulasitiki a zomangamanga monga PP, PA, ABS, APC, PVC, PBT, EPDM, PMMA, ndi zina;

4. Valani zinthu zosagonjetsedwa: magudumu amphero yamadayamondi, gudumu lolemera, chopumira, chidebe chomata chomata, zida zamaginito, ndi zina zambiri;

5. Mbali zina za feteleza wamafuta (synthetic ammonia) makina ndi zida zopanda mafuta, zopangira zosunthika komanso malo amodzi osindikizira ndi zina zambiri zapamwamba.

Kutentha kukana

BMI imakhala yotentha kwambiri chifukwa cha mphete yake ya benzene, imide heterocycle komanso kukhathamira kwakukulu. TG yake imakhala yayikulu kuposa 250 ℃, ndipo kutentha kwake kantchito kumakhala pafupifupi 177 ℃ ~ 232 ℃. Mu aliphatic BMI, ethylenediamine ndiye wolimba kwambiri. Ndi kuchuluka kwa nambala ya methylene, kutentha koyambirira kwa kutentha (TD) kumachepa. TD ya BMI onunkhira nthawi zambiri imakhala yayikulu kuposa ya aliphatic BMI, ndipo TD ya 2,4-diaminobenzene ndiyokwera kuposa mitundu ina. Kuphatikiza apo, pali ubale wapamtima pakati pa TD ndi kachulukidwe kowoloka. Pakati pamtundu winawake, TD imakulira ndikuwonjezeka kwa kuchuluka kwa olumikiza.

Kusungunuka

BMI yomwe imagwiritsidwa ntchito nthawi zambiri imatha kusungunuka m'mazinyalala monga acetone ndi chloroform, ndipo imatha kusungunuka m'madzi olimba, poizoni komanso zotchipa monga dimethylformamide (DMF) ndi N-methylpyrrolidone (NMP). Izi zimachitika chifukwa cha kuchuluka kwa ma molekyulu komanso mawonekedwe a BMI.

Mawotchi katundu

Kuchiritsa kwa utomoni wa BMI ndiwowonjezera polima, yomwe ilibe zotsika zochepa zamagulu ndi zosavuta kuwongolera. Chifukwa chakapangidwe kake komanso zolakwika zochepa, BMI ili ndi mphamvu zapamwamba komanso modulus. Komabe, chifukwa cha kuchuluka kwa maulalo olumikiza komanso kulimba kwamphamvu kwa mankhwala ochiritsidwa, BML imapereka kuwonongeka kwakukulu, komwe kumadziwika ndi mphamvu zopanda mphamvu, kutalika kwakanthawi kochepa komanso kulimba kochepa g1c (<5J / m2). Kulimba molakwika ndi cholepheretsa chachikulu kuti BMI izolowere njira zapamwamba komanso kukulitsa magawo atsopano ogwiritsira ntchito, chifukwa chake kulimbitsa kulimba kwakhala imodzi mwamaukadaulo ofunikira kuti agwiritse ntchito ndikukula kwa BMI. Kuphatikiza apo, BMI ili ndimagetsi abwino kwambiri, mankhwala osagwirizana ndi ma radiation.

Wazolongedza: 20kg / thumba

Kusamala: sungani mnyumba yosungira yozizira, youma komanso yopuma.

Mphamvu yapachaka: Matani 500 / chaka
