Cov Photoresists & Photoreactive Polymers: Siv rau hauv kev tsim cov photoresist resins rau cov phaj luam ntawv thiab cov khoom siv hluav taws xob (semiconductors, LCDs).
Cov nplaum thiab cov khoom foob:
Txhim kho lub zog lo rau ntau yam substrates, suav nrog cov hlau thiab cov yas.
Ua kom cov kab sib txuas sib txuas zoo dua, ua rau muaj kev tiv taus cua sov zoo dua, tiv taus tshuaj lom neeg, thiab muaj zog sib koom ua ke hauv cov nplaum uas muaj cov qauv thiab cov nplaum uas rhiab siab (PSAs).
Cov Ntaub Ntawv & Cov Fibers:
Siv ua ib qho co-monomer hauv cov neeg sawv cev kho fiber thiab cov ntaub txheej kom muab cov dej tsis kam, tiv taus wrinkle, thiab ruaj khov.
Kev Ua Ntawv:
Siv rau hauv cov txheej txheem txheej kom txhim kho lub zog ntub thiab qhuav, tiv taus dej, thiab luam tawm tau.
Cov Ntawv Thov Tshwj Xeeb:
Kev Lag Luam Lubricant: Ua haujlwm ua cov tshuaj nruab nrab rau kev tsim cov tshuaj ntxuav thiab cov khoom ntxiv rau dispersant.
Electronics: Siv ua tus neeg sawv cev dehydration hauv kev npaj cov qauv electron microscopy.
Kev Tshuaj Xyuas Txog Tshuaj: Ua haujlwm ua cov tshuaj reagent thiab ua ib feem ntawm cov neeg sawv cev uas sib xyaw nrog dej.
Cov Nta Tseem Ceeb & Cov Txiaj Ntsig
Kev Ua Haujlwm Ob Zaug: Pawg acrylate ua rau copolymerization, thaum pawg hydroxyl tso cai rau kev sib txuas thiab kev hloov pauv tshuaj.
Kev Ua Tau Zoo Dua: Ua kom muaj kev ruaj khov zoo, tiv taus tshuaj lom neeg, thiab lo rau cov polymers kawg.
Kev Ua Haujlwm Siab: Yooj yim copolymerizes nrog acrylates, methacrylates, styrene, vinyl acetate, acrylonitrile, thiab ntau dua.
Kev Siv Tau Ntau Yam: Haum rau ntau yam txheej txheem polymerization, suav nrog kev daws teeb meem, emulsion, thiab kev ncua polymerization.
Kev Ua Haujlwm Zoo: Muab kev txhim kho zoo hauv cov khoom lag luam txawm tias ntawm qib qis ntawm kev koom ua ke (feem ntau 2-10%).
Qhov Tsis Muaj Viscosity: Ua haujlwm ua cov tshuaj diluent zoo hauv cov kab ke kho tau los ntawm kev siv hluav taws xob, pab txo qhov viscosity ntawm cov tshuaj yam tsis siv cov tshuaj volatile organic (VOCs).
Kev Tswj Xyuas & Kev Khaws Cia
Kub Cia Khoom: Khaws cia rau qhov chaw txias thiab muaj cua nkag tau zoo. Qhov kub cia khoom uas pom zoo yog ntawm 2°C thiab 25°C (36°F thiab 77°F). Tsis txhob cia kom khov thiab kub dhau.
Tshuaj Tiv Thaiv: Muaj MEHQ inhibitor kom tiv thaiv kev sib xyaw ua ke yam tsis tau npaj tseg. Cov tshuaj tiv thaiv no yuav tsum muaj oxygen thiaj li ua haujlwm tau; yog li ntawd, kev khaws cia rau hauv qab huab cua inert (piv txwv li, Nitrogen padding) yog qhov tseem ceeb rau kev ruaj khov mus sij hawm ntev.
