Ntxiv nrog rau cov yas tseem ceeb, txheej txheej hloov kho tshuaj ntxiv, lub tuam txhab tau nthuav dav nthuav dav mus rau thaj chaw dav, txhawm rau txhim kho cov khoom lag luam rau cov neeg siv ntau dua.
Lub tuam txhab tuaj yeem muab cov khoom lag luam molecular sieve, 6FXY
(2,2-Bis (3,4-dimethylphenyl) hexafluoropropane) thiab 6FDA (4,4 '-(Hexafluoroisopropylidene) diphthalic anhydride).

| MOLECULAR SIEVE | / | Molecular sieve hais txog qhov sib xws me me pore, nws lub qhov taub thiab qhov dav dav ntawm cov khoom me me ntawm chav kawm ntawm cov tshuaj. Feem ntau siv cov txheej txheem molecular rau crystalline silicate lossis silicon aluminate, yog tsim los ntawm silicon oxygen tetrahedron lossis aluminium oxygen tetrahedron los ntawm cov pa oxygen sib cog thiab tsim cov qauv me me (feem ntau 0.3 ~ 2 nm) ntawm lub qhov thiab kab noj hniav, vim yog kev nqus cov qauv me me thiab zoo thiab muaj peev xwm tshuaj ntsuam cov kua dej sib txawv ntawm qhov sib txawv. |

65294-20-4 | 6FDA yog cov organic sib txuas ua ke nruab nrab thiab cov tshuaj nruab nrab, uas tuaj yeem siv hauv kev tshawb fawb tshawb fawb thiab txhim kho cov txheej txheem thiab txheej txheem tshuaj tsim tshuaj tsim tshuaj, feem ntau yog cov khoom siv hluav taws xob polymer. Hexafluoradianhydride (6FDA) yog ib ntawm rau rau feem ntau siv dianhydride monomers, thiab tseem siv dav hauv dianhydride monomer hauv cov xim tsis muaj pob tshab polyimide. Polyimide synthesized los ntawm hexafluoradianhydride (6FDA) feem ntau muaj cov iav hloov pauv kub siab dua 300 ° C thiab cov cuab yeej siv hluav taws xob zoo. Txog tam sim no, nws tseem yog tus sawv cev tshaj plaws fluorinated polyimide. Daim ntawv thov kawg yog lub xov tooj ntawm tes folding screen, thaum peb lub tuam txhab tau ua tiav txhawb rau lub ntiaj teb tus neeg sawv cev hloov pauv polyimide cov tuam txhab.

Koj zoo siab hu rau peb kom paub ntau ntxiv. txog cov khoom.
Txhawm rau muab cov tshuaj polymer ntxiv rau hauv cov ntawv thov tshwj xeeb, lub tuam txhab tau tsim cov khoom lag luam npog hauv qab daim ntawv thov: PA polymerization & hloov kho ntxiv, PU ua npuas dej ntxiv, PVC polymerization & kev hloov kho ntxiv, PC ntxiv, TPU elastomer additives, qis VOC tsheb laij cov tshuaj ntxiv additives tus neeg sawv cev, txheej txheej ntxiv, tshuaj pleev ib ce ntxiv, API thiab lwm yam khoom siv tshuaj xws li zeolite thiab lwm yam.
Koj ib txwm tos txais hu rau peb rau kev nug!
