Kev Siv
Hexahydrophthalic anhydride (HHPA) yog ib qho khoom siv tseem ceeb hauv kev lag luam tshuaj lom neeg uas muaj ntau yam kev siv:
- Hauv kev ua cov txheej txheej: Nws tuaj yeem koom nrog kev npaj ntau yam polyester resins ua tau zoo. Cov txheej txheej ua los ntawm cov resins no muaj kev nplaum zoo heev, tiv taus tshuaj lom neeg, thiab tawv. Hauv kev tiv thaiv kev lag luam thiab cov txheej txheej tsheb, kev siv cov polyester resins uas muaj hexahydrophthalic anhydride tsis tsuas yog tiv taus kev yaig ntawm cov kua qaub sab nraud, alkalis, thiab cov kuab tshuaj tab sis kuj tswj tau qhov ci thiab kev ncaj ncees ntawm cov txheej txheej ntev, muab kev tiv thaiv mus sij hawm ntev rau cov khoom coated.
- Hais txog cov khoom siv hluav taws xob thiab hluav taws xob: Nws yog siv dav hauv kev tsim cov tshuaj epoxy resin curing agents. Tom qab kho nrog hexahydrophthalic anhydride, cov epoxy resin tsim cov ntaub ntawv nrog cov khoom rwb thaiv tsev zoo heev thiab kev ruaj khov thermal zoo. Hauv cov ntawv luam tawm Circuit Court thiab cov ntaub ntawv ntim khoom hluav taws xob, nws tuaj yeem ua kom ntseeg tau tias kev ua haujlwm ruaj khov ntawm cov khoom siv hluav taws xob thiab tiv thaiv kev ua haujlwm hluav taws xob xws li luv luv thiab xau.
- Hauv cov xwm txheej siv ntawm cov ntaub ntawv sib xyaw: Ua cov khoom siv tseem ceeb rau cov polyester resins tsis muaj roj, thaum ua ke nrog cov ntaub ntawv txhawb nqa xws li cov iav fiber, cov ntaub ntawv fiberglass sib xyaw tsim tawm muaj zog thiab lub teeb hauv qhov hnyav. Lawv feem ntau siv rau hauv kev tsim khoom ntawm aerospace, nkoj, thiab tsheb qhov chaw, xws li cov vaj huam sib luag sab hauv dav hlau, lub nkoj hulls, thiab lub cev tsheb npog. Thaum ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv kho tshuab, lawv kuj ua tiav qhov sib dua ntawm cov khoom.
- Hauv kev lag luam nplaum: Hexahydrophthalic anhydride tuaj yeem kho qhov kev kho thiab lub zog sib txuas ntawm cov nplaum. Nws ua rau cov nplaum tsis yog tsuas yog muaj kev sib txuas zoo thaum pib tab sis kuj tseem muaj kev sib txuas ntev. Nws yog siv dav rau kev sib txuas ntawm cov ntaub ntawv sib txawv xws li hlau, yas, thiab ntoo. Piv txwv li, cov txheej txheem nplaum hauv kev sib dhos rooj tog thiab kev sib dhos khoom siv hluav taws xob tsis tuaj yeem ua yam tsis muaj nws.
Ntim thiab Xa Khoom
25KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Kev Xa Khoom: 8 hom khoom txaus ntshai thiab tuaj yeem xa los ntawm dej hiav txwv.
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
