Nitsumɔhei Wuji

1. Polymer Nitsumɔhe: Nibii ni Tsuɔ Nii ni Nɔ Kwɔ lɛ Anyɛɔ Atsuɔ Nii
DMAc ji shishitoo tɛ yɛ polymers ni etee hiɛ lɛ afeemɔ mli, titri lɛ yɛ fibers kɛ sinii ni he wa waa lɛ afeemɔ mli:
Aramid tsɔji:
Yɛ aramid fibers (tamɔ, Kevlar®) feemɔ mli lɛ, DMAc tsuɔ nii akɛ nɔ ni haa anáa polyamide polymerization, ni ehaa anyɛɔ afee nibii ni he wa waa ni akɛtsuɔ nii yɛ tsɔnei ni akɛwoɔ tu mli, kɔɔyɔŋ mli nibii ni akɛfee nibii, kɛ nitsumɔhei kpãai amli. Akɛ nɔkwɛmɔnɔ lɛ, U.S. tawuu he nitsumɔhei lɛ kɛ amɛhe fɔ̃ɔ DMAc nɔ koni amɛfee aramid fibers ni hewalɛ ni tsiɔ amɛhe lɛ feɔ 3,600 MPa.
Polyimide sinii:
Kɛ akɛtsu nii yɛ polyimide (PI) sinii (tamɔ, Kapton®) feemɔ mli lɛ, DMAc lɛ shwieɔ polyamic acid nibii ni tsɔɔ hiɛ lɛ anɔ, ni ehaa anyɛɔ akudɔɔ sini lɛ mli ŋmɔlɔ kɛ nibii ni haa mɔ naa nii lɛ pɛpɛɛpɛ. Nɛkɛ sinii nɛɛ he hiaa waa yɛ tsɔnei ni anyɛɔ atsakeɔ amɛhe (tamɔ, OLED nibii ni ajieɔ atsɔɔ, PCBs ni anyɛɔ atsakeɔ amɛhe) kɛ tsɔnei ni haa hulutsoo baa lɛ amli.
Spandex kɛ nibii ni akɛfee nibii:
Yɛ atadei afeemɔ mli (tamɔ, Asia spandex tsei lɛ), DMAc haa polyurethane tsɔji lɛ atsɔne lɛ feɔ mlɛo, ni ehaa atadei ni akɛtsuɔ nii kɛfeɔ shwɛmɔ atadei kɛ tsofafeemɔ mli atadei ni akɛwoɔ tsɔne mli lɛ mli lɛ mli lɛ feɔ ekome.

2. Tsofafeemɔ kɛ Biotechnology: Nɔ ni haa nu kɛ nɔ ni haa mɔ tsui nyɔɔ emli
Tsofai Afeemɔ:
DMAc tsuɔ nii akɛ nɔ ko ni yɔɔ srɔtoi yɛ tsofafeemɔ mli nibii ni yɔɔ teŋgbɛ kɛ tsofafeemɔ mli nibii ni tsuɔ nii (API) feemɔ mli. Hewalɛ ni eyɔɔ ni ekɛjieɔ nibii ni wala yɔɔ amɛmli kɛ nibii ni wala bɛ mli lɛ fɛɛ lɛ haa efeɔ nɔ ni hi jogbaŋŋ kɛha ŋmɔtɔ, ŋmɔtɔ, kɛ oksideshin nifeemɔi. Akɛ nɔkwɛmɔnɔ lɛ, akɛtsuɔ nii yɛ tsofai ni gbeɔ hela ni haa mɔ he jɔ̃ɔ ehe (tamɔ, HIV protease inhibitors) lɛ afeemɔ mli yɛ Europa tsofafeemɔ nitsumɔhei.
Nɔ ni akɛyeɔ abuaa:
Yɛ tsofai ni akɛwoɔ mɔ he lɛ amli (tamɔ, tsofai ni akɛwoɔ mɔ mli, tsofai ni akɛwoɔ mɔ he lɛ), DMAc haa tsofai ni haa mɔ he jɔɔ lɛ boteɔ hewolo lɛ mli, ni ehaa tsofai ni haa mɔ he jɔɔ lɛ yaa hiɛ. Akɛtsuɔ nii hu yɛ tsofai ni akɛwoɔ mɔ mli lɛ amli yɛ bɔ ni eyɔɔ gbeyei waa lɛ hewɔ, ni ekɛ gbɔmɔ gbɔmɔtso lɛ kpãa gbee (LD50 > 3,000 mg/kg yɛ ŋmeii amli).
Biotech nitsumɔi:
Yɛ tsofafeemɔ mli lɛ, akɛ DMAc tsuɔ nii yɛ protein hetsemɔ gbɛjianɔtoi amli, tamɔ chromatography, koni ekɛha protein ni yɔɔ membrane mli lɛ afee ŋmɔtɔ ni eha mligbalamɔ aya hiɛ.

3. Elektrɔnik kɛ Semiconductor nitsumɔhe: Nɔ ni akɛtsuɔ nii pɛpɛɛpɛ kɛha nibii bibii afeemɔ
Fotoresist jiemɔ:
Yɛ semiconductor feemɔ mli lɛ, akɛ DMAc tsuɔ nii yɛ hetsemɔ gbɛjianɔtoi ni etee hiɛ lɛ amli koni akɛjie fotoresist ni yɔɔ ŋmɔlɔŋmɔlɔ ni eshwɛ kɛjɛ silicon wafers mli. Ehewalɛ ni nɔ kwɔ kɛha epoxy - ni damɔ shi kɛha fotoresists lɛ haa efeɔ nɔ ni he hiaa waa yɛ nanolithography mli (tamɔ, EUV lithography kɛha 3nm chip nodes).
OLED kɛ Kpojiemɔ Nifeemɔ:
Yɛ nibii ni wala yɔɔ mli ni haa kane kpɛɔ (OLEDs) lɛ afeemɔ mli lɛ, DMAc shwieɔ nibii ni wala yɔɔ mli ni haa kane kpɛɔ kɛ nibii ni akɛwoɔ mli lɛ amli, ni ehaa sini ni yɔɔ mlɛo lɛ feɔ ekome kɛtsɔɔ inkjet kalamɔ loo spin-coating nɔ. Koreabii ni feɔ nibii ni ajieɔ lɛ kpo lɛ kɛ DMAc tsuɔ nii koni amɛna pixel pɛpɛɛpɛ kɛyashi micrometer skel nɔ.
Elɛktroplating kɛ Etching:
Etsuɔ nii akɛ nɔ ni akɛwoɔ shika tsuru kɛ akɔɔble mli, ni ehaa shika ni akɛwoɔ mli lɛ feɔ ekome yɛ tsɔnei ni akɛwoɔ tsɔne mli ni etee hiɛ lɛ amli (tamɔ, 3D ICs, fan - out wafer level packaging).

4. Atadei kɛ Hewolo He Nitsumɔ: Tsabaai ni Hiɔ Shi Daa
Fiber ni akɛfee nibii:
Yɛ akrɛliki fibers feemɔ mli lɛ, DMAc yeɔ tsofai ni yɔɔ gbeyei babaoo najiaŋ (tamɔ, dimethylformamide, DMF), ni ekɛ tsofai ni akɛtoɔ he ni shihilɛ mli nibii ni yɔɔ mli lɛ baa shi lɛ haa. Europe atadefeemɔ nitsumɔhei kɛ DMAc tsuɔ nii yɛ shihilɛ ni OEKO-TEX® Standard 100 etsɔɔ mli.
Hewolo Tanning:
Akɛ nɔ ni akɛtoɔ blema tsofai ni akɛfeɔ hewolo lɛ najiaŋ lɛ, DMAc haa tsofa-kɛ-ŋma mli tannins lɛ boteɔ mli jogbaŋŋ, ni ehaa hewolo ni yɔɔ blɛoo ni haa mɔ mumɔ nyɛɔ etsuɔ ​​nii jogbaŋŋ kɛhaa nibii ni jara wa (tamɔ, Italia hewolo kotokui). Ehewalɛ ni baa shi lɛ haa VOC ni ajieɔ kɛjɛɔ tsɔnei ni akɛfeɔ tsɔnei ni akɛwoɔ tsɔne mli lɛ amli lɛ baa shi.

5. Nitsumɔhei Amli Hetsemɔ kɛ Nibii ni Ajieɔ kɛjɛɔ Mli: Nitsumɔ kɛ Shweshweeshwefeemɔ
Dade ni ajieɔ mu kɛjɛɔ mli:
Yɛ kɔɔyɔŋ lɛlɛ kɛ tsɔnei ahe nitsumɔhei lɛ, DMAc jieɔ mu, mu, kɛ flux nibii ni eshwɛ kɛjɛɔ nibii ni akɛtsuɔ nii pɛpɛɛpɛ lɛ amli (tamɔ, turbine blades, tsɔne lɛ fãi). E-boiling point ni nɔ kwɔ (166°C) lɛ haa hulutsoo fioo ko pɛ shwieɔ shi yɛ ultrasonic hetsemɔ be mli, ni ehaa hulutsoo nibii ni fiteɔ lɛ baa shi.
Adebɔɔ mli nibii ni ajieɔ kɛjɛɔ mli:
Kɛ akɛtsu nii yɛ adebɔɔ mli ŋmɔlɔi (tamɔ, carotenoids kɛjɛ ŋmeii amli) kɛ tsofai ni jɛ tsei amli lɛ ajiemɔ mli lɛ, DMAc haa tsɔne ni haa mɔ tsui nyɔɔ emli ni efiteee nibii ni akɛtsuɔ nii ni akɛtaoɔ nii lɛ amli lɛ.
