Kub thiab tshav ntuj yuav cuam tshuam rau lub sij hawm cia ntawm unsaturated polyester resin.Qhov tseeb, txawm tias nws tsis yog polyester resin los yog lwm yam resins, qhov chaw cia kub yog qhov zoo dua 25 degrees Celsius hauv cheeb tsam tam sim no.Nyob rau lub hauv paus no, qhov kub thiab txias, lub sij hawm ntev ntawm lub unsaturated polyester resin;qhov kub siab dua, lub sijhawm siv tau luv dua.
Cov resin yuav tsum tau muab kaw thiab khaws cia rau hauv lub thawv qub kom tsis txhob poob ntawm monomer volatilization thiab poob ntawm lwm impurities.Thiab lub hau ntawm lub ntim ntim rau khaws cov resin yuav tsum tsis txhob ua los ntawm tooj liab lossis tooj liab alloy, nyiam dua polyethylene, polyvinyl chloride thiab lwm yam hlau hau.
Feem ntau hais lus, nyob rau hauv qhov kub thiab txias, tsis txhob tshav ntuj ncaj qha rau lub ntim ntim, tab sis lub sij hawm cia tseem yuav cuam tshuam, vim hais tias nyob rau hauv cov huab cua kub, lub gel lub sij hawm ntawm resin yuav luv luv ntau, yog hais tias nws yog ib tug tsis zoo resin. , txawm yuav ncaj qha solidify nyob rau hauv lub thawv ntim.Yog li ntawd, thaum lub sij hawm kub kub, yog tias muaj kev tso cai, nws yog qhov zoo tshaj rau khaws cia rau hauv lub tsev khaws khoom cua txias nrog qhov kub ntawm 25 degrees Celsius.Yog tias cov chaw tsim khoom tsis npaj lub tsev khaws khoom cua txias, nws yuav tsum tau them sai sai rau lub sijhawm khaws cia ntawm cov resin.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov resin tov nrog styrene yuav tsum tau kho raws li flammable hydrocarbons los tiv thaiv hluav taws.Yuav tsum muaj kev tswj xyuas nruj heev ntawm cov tsev khaws khoom thiab cov nroj tsuag uas khaws cov khoom siv no, thiab kev tiv thaiv hluav taws thiab kev sib tsoo yuav tsum tau ua txhua lub sijhawm.
Cov teeb meem kev nyab xeeb uas yuav tsum tau them sai sai rau thaum lub sij hawm ua cov khoom siv tsis zoo polyester resin hauv kev cob qhia
1. Resin, curing agent, thiab accelerator yog tag nrho cov khoom siv hluav taws xob, yog li kev tiv thaiv hluav taws yuav tsum tau saib xyuas, thiab lawv yuav tsum tau muab khaws cia nyias, txwv tsis pub nws yooj yim heev ua rau tawg.
2. Yuav tsum tsis muaj kev haus luam yeeb thiab tsis muaj hluav taws kub hauv qhov chaw ua haujlwm tsim khoom.
3. Lub rooj cob qhia ntau lawm yuav tsum ua kom muaj cua txaus.Muaj ob hom kev ua haujlwm ntawm qhov cua, ib qho yog tswj cov huab cua sab hauv tsev, thiaj li tshem tawm cov styrene volatile txhua lub sijhawm.Vim hais tias styrene vapor yog denser tshaj huab cua, styrene concentration nyob ze hauv av kuj tseem siab.Yog li ntawd, qhov tso pa tawm hauv lub rhiav yog qhov zoo tshaj plaws nyob ze rau hauv av.Lwm qhov yog siv cov cuab yeej thiab cov cuab yeej siv hauv zos kom tshem tawm qhov chaw ua haujlwm.Piv txwv li, teeb tsa lub kiv cua cais tawm kom tshem tawm cov siab-concentration styrene vapor los ntawm qhov chaw ua haujlwm, lossis tso cov pa hluav taws xob los ntawm lub ntsiab nqus cov yeeb nkab uas tau teeb tsa hauv lub rhiav.
4. Txhawm rau tiv thaiv cov xwm txheej tsis txaus ntseeg, lub rooj cob qhia tsim khoom yuav tsum muaj tsawg kawg yog ob qhov tawm.
5. Cov resin thiab ntau yam accelerators khaws cia rau hauv lub rhiav ntau lawm yuav tsum tsis txhob ntau dhau, nws yog qhov zoo tshaj rau khaws cia me me.
6. Cov resins uas tsis tau siv tab sis tau ntxiv nrog cov accelerators yuav tsum tau hloov mus rau qhov chaw muaj kev nyab xeeb thiab khaws cia sib cais kom tsis txhob muaj cua sov ntau los ntawm kev sib sau ua ke thiab ua rau tawg thiab hluav taws.
7. Thaum cov polyester resin tsis muaj dej ntws tawm thiab ua rau hluav taws kub, cov pa phem yuav raug tso tawm hauv cov txheej txheem thiab ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.Yog li ntawd, kev ntsuas kub ceev yuav tsum tau ua los daws nws.
