Thoob Ntiaj Teb - Premier MOCA: Cov Tshuaj Zoo Rau Cov Kev Siv Tshwj Xeeb
Cov Ntawv Thov Tseem Ceeb
MOCA feem ntau yog siv rau hauv kev lag luam polyurethane5. Nws ua haujlwm ua tus neeg sawv cev kho thiab txuas cov saw hlau, ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv polyurethane ua tau zoo5. Hauv kev tsim cov khoom polyurethane cam khwb cia xws li lub log skateboard, ntau hom roj hmab rollers, pwm linings, hydrocyclones, siv kis, couplings, sieves, thiab cov khoom sealing, MOCA pab txhim kho cov khoom siv kho tshuab, xws li lub zog, qhov nyuaj, thiab kev tiv thaiv hnav ntawm cov khoom kawg5. Nws ntxiv kuj tseem tuaj yeem txhim kho kev ua haujlwm thiab kev ruaj khov ntawm cov khoom siv polyurethane, kom ntseeg tau tias muaj kev sib xws thiab zoo ntawm cov khoom.
Cov khoom no kuj siv tau rau hauv kev kho cov epoxy resins5. Nws cuam tshuam nrog cov pab pawg epoxy hauv epoxy resins los tsim cov qauv sib txuas, txhim kho qhov tiv taus cua sov, tiv taus tshuaj lom neeg, thiab lub zog kho tshuab ntawm cov epoxy resins kho. Qhov no ua rau epoxy resins tsim nyog dua rau kev siv hauv qhov chaw nyuaj, xws li hauv cov teb ntawm cov txheej txheem, cov nplaum, thiab cov khoom sib xyaw.

Hauv kev xaus lus
Peb cov MOCA yog tsim los ntawm kev siv thev naus laus zis siab heev thiab kev tswj xyuas zoo nruj heev. Nws muaj ntau hom, suav nrog cov hmoov dawb (me ntsis daj) thiab cov hmoov daj daj4. Nws muaj qhov kub siab tshaj plaws ntawm 98 ℃, cov dej noo tsawg, thiab qhov huv ntawm tsis tsawg dua 86%4. Cov khoom no tau ntim rau hauv cov hnab ntawv kraft tsis muaj dej nrog cov hnab yas dub sab hauv, nrog qhov hnyav tag nrho ntawm 25 kg ib lub hnab, uas yooj yim rau kev khaws cia thiab kev thauj mus los4. Txawm tias koj yog lub tuam txhab tsim khoom polyurethane hauv Asia, lub tuam txhab ua tshuaj hauv Tebchaws Europe, lossis tus tsim khoom siv epoxy resin hauv North America, peb lub Global - Premier MOCA yog qhov kev xaiv zoo tshaj plaws los ua kom tau raws li koj cov kev xav tau tshwj xeeb, pab koj tsim cov khoom zoo thiab tau txais kev sib tw hauv kev ua lag luam.
