Tsis ntev los no, nyob rau theem ntawm kev lag luam tshuaj, hexahydrophthhalic anhydride anhydride (HHPA), muaj cov khoom siv raw tshuaj raw, tau dhau los ua cov ncauj lus kub. Raws li qhov sib txuas nrog kev ua tau zoo, Hexahydrophthhalic anhydride ua lub luag haujlwm tseem ceeb hauv ntau daim teb muaj ntau yam teb. Cov tshiab ntawm cov kev tsim kho tshiab tam sim no hauv nws cov lag luam thiab cov ntawv thov tau ua rau nthwv dej.
Hexahydrophthhalic anhydride yog tog dawb los yog cov kua tawv. Nrog nws cov cim tshuaj lom neeg xws li, nws muaj kev sib tw ntawm cov kab sib txuas, suav nrog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob, thiab cov nplaum. Nyob rau hauv lub teb txheej, kev ua haujlwm siab polyester resins nws koom nrog hauv synthesizing yog zoo li "Boost txhaj" rau kev lag luam tiv thaiv cov xim thiab cov duab sab topcoats. Tam sim no, kev tsim khoom lag luam tau nce raws li txoj hlua khi kom ua rau cov tsos thiab cov khoom siv ruaj khov. Siv polyester cob cov txheej txheem hexahydrophtharicic anhydride tsis tuaj yeem ua rau cov khoom siv los ntawm cov cua, thiab ua haujlwm txuas ntxiv rau cov khoom lag luam thiab cov khoom lag luam kom txo cov nqi thiab nce ntxiv.
Cov cuab yeej siv hluav taws xob thiab hluav taws xob kev lag luam yog qhov chaw nyom ntawm cov ci ntsa iab. Tam sim no, cov khoom siv hluav taws xob tau hloov mus ib txwm txav mus los ntawm miniaturization thiab kev ua tau zoo, thiab lawv muaj qhov xav tau siab heev rau cov rwb thaiv tsev thiab hluav taws xob stability ntawm cov khoom sab hauv. Lub Epoxy Resin Chais cov neeg sawv cev ua los ntawm hexahydride anhydride ntim cov khoom lag luam thiab hluav taws xob rwb thaiv tsev "daim thaiv rau", tshem tawm cov kev pheej hmoo ntawm cov kev pheej hmoo ntawm lub luv luv. Txawm tias thaum kub tau teev thaum lub sijhawm ua haujlwm ntev, muaj peev xwm tswj tau lub siab "ntawm cov khoom siv hluav taws xob thiab ua haujlwm ruaj khov ntawm cov khoom siv.
Hauv thaj teb ntawm cov khoom siv sib xyaw, ua cov khoom siv raw rau cov khoom tsis muaj txiaj ntsig, ua ke nrog cov khoom lag luam zoo li iav thiab cov khaub ncaws zoo li iav thiab cov khoom lag luam zoo li cov khoom siv - cov khoom siv roj ntsha - fiberglass sib xyaw. Nrog rau kev sib raug zoo ntawm cov phiaj xwm dav hlau loj thiab kev hloov pauv ntawm cov khoom lag luam loj, cov khoom siv hluav taws xob siab sib ntsib ntawm kev lag luam. Lawv pab kom cov dav hlau kom ua rau "hnyav dhau" kom ya mus ntxiv thiab ntau zog-ua tau zoo, thiab tseem ua rau nkoj ntau dua ntawm dej.
Nws yog tsim nyog teev tias cov khoom siv xa-thov hauv Hexahydrophthalic anhydrride kev ua lag luam tau hloov ntsiag to tsis ntev los no. Nrog rau kev nthuav dav nthwv dej hauv cov kev lag luam hauv qab dej, qhov xav tau sab tau muaj muaj zog nce siab, thiab cov kev txiav txim siab ntawm kev lag luam cuam tshuam txog kev lag luam cuam tshuam yog nce qib lub hli. Txhawm rau kom tau raws li qhov kev thov loj hlob, loj hexahydrophthhalic anhydride anread processing. Qee tus tau nrawm dua qhov kev hloov pauv ntse ntawm cov kab ntau lawm los txhim kho ntau yam kev ua haujlwm zoo thiab kev qhia txog cov cuab yeej siv tshiab, ua rau nthuav tawm lawv cov peev xwm ntau lawm.
Txawm li cas los xij, cov cib fim feem ntau nrog cov nyom. Hexahydrophthalic anhydride belongs rau chav kawm 8 cov khoom txaus ntshai, thiab cov kab kev nyab xeeb yuav tsum tau ua raws li thaum lub sijhawm thiab khaws cia. Cov chaw saib xyuas tsis ntev los no tau tsis ntev los no kev saib xyuas, koj cov lag luam uas tswj hwm siv cov kev tswj hwm rau cov tshuaj tua neeg. Los ntawm cov kev faib cov tsheb thauj tshwj xeeb rau cov kev tshuaj xyuas ib txwm muaj los ntawm kev tiv thaiv, thiab lwm yam kev nyab xeeb ntawm kev tiv thaiv hluav taws xob hauv qab no.
Kev lag luam insiders insiders txheeb xyuas cov hexahydrophthhalic anhydride muaj peev xwm loj heev rau yav tom ntej. Tsuav cov teeb meem ntawm kev nyab xeeb ntau lawm thiab cov khoom ruaj khov yog kov yeej kev txhim kho thiab kev txhim kho cov "tseem ceeb" tom qab kev lag luam zoo tshaj plaws ntawm kev lag luam.
