Hydroxyethylenediamine ili ndi mwayi waukulu pamsika

Magawo Ogwiritsira Ntchito: Hydroxyethylenediamine imagwiritsidwa ntchito kwambiri mu zodzoladzola, mankhwala, mankhwala ophera tizilombo, mapulasitiki ndi madera ena. Ndi chitukuko cha mafakitale osiyanasiyana, kufunikira kwake pamsika kukupitilirabe kukwera.
Mtengo wamsika: Malinga ndi momwe msika wasinthira, mtengo wa hydroxyethylethylenediamine umasinthasintha. Mwachitsanzo, mtengo ku Hubei mu Okutobala 2024 ndi 53,000 yuan/tani, pomwe mtengo ku Shandong ndi 21,300 yuan/tani. Kusiyana kwa mitengo pakati pa madera osiyanasiyana ndi mitundu yosiyanasiyana ndi kwakukulu.
Msika: Chifukwa cha kupita patsogolo kosalekeza kwa makampani opanga mankhwala padziko lonse lapansi komanso kusintha kwa miyoyo ya anthu, chiyembekezo cha msika wa hydroxyethylethylenediamine ndi chachikulu kwambiri. M'tsogolomu, chifukwa cha kukula kosalekeza kwa malo ogwiritsira ntchito komanso kukula kosalekeza kwa kufunikira kwa msika, kukula kwa msika wa hydroxyethylethylenediamine kukuyembekezeka kukula kwambiri.
Mwachidule, monga chinthu chofunikira kwambiri cha mankhwala achilengedwe, hydroxyethylethylenediamine imagwiritsidwa ntchito kwambiri m'magawo ambiri ndipo ili ndi chiyembekezo chabwino pamsika. Koma nthawi yomweyo, mtengo wake pamsika umasinthasintha, ndipo ndikofunikira kuyang'anitsitsa momwe msika ukugwirira ntchito kuti pakhale njira zoyenera zogulira ndi kugulitsa.

Kugwiritsa ntchito hydroxyethylenediamine

Hydroxyethylethylenediamine, yomwe imadziwikanso kuti wothandizira kuchiritsa nambala 1, ndi mankhwala achilengedwe omwe amagwiritsidwa ntchito m'njira zosiyanasiyana, makamaka kuphatikiza izi:

Zipangizo zopangira mankhwala: Monga chinthu chofunikira kwambiri chamankhwala komanso chamankhwala tsiku ndi tsiku, chingagwiritsidwe ntchito popanga zoletsa dzimbiri, zolimbitsa kuwala, zothamangitsa vulcanization, ndi zina zotero.
Chopangira zinthu zopindulitsa: Ndicho chinthu chachikulu chomwe chimagwiritsidwa ntchito popanga ma surfactants a imidazoline a cationic ndi zwitterionic, ndipo mtundu uwu wa surfactant umapanga gawo lalikulu la mphamvu yonse yopangira.
Epoxy resin curing agent: Monga mankhwala abwino kwambiri ochepetsa kutentha kwa chipinda omwe sawononga poizoni wa epoxy resin, amagwiritsidwa ntchito ndi epoxy resin ndipo amagwiritsidwa ntchito kwambiri polumikiza zitsulo ndi zinthu zina zosakhala zitsulo, kukonza zokutira za epoxy zotsutsana ndi dzimbiri, ndi zina zotero.
Ntchito zina: Itha kugwiritsidwanso ntchito popanga utoto, ma resins, rabara, zinthu zoyandama, mankhwala ophera tizilombo, komanso ngati zowonjezera mafuta, zitsulo zomatira ma ion, ndi zina zotero.
Mwachidule, hydroxyethylethylenediamine imagwiritsidwa ntchito m'njira zosiyanasiyana chifukwa cha mphamvu zake zapadera za mankhwala komanso kusinthasintha kwake.
