Ob qhov kub thiab lub hnub ci tuaj yeem cuam tshuam rau lub sijhawm khaws cia ntawm cov khoom siv polyester tsis zoo.Qhov tseeb, txawm hais tias nws yog unsaturated polyester resin los yog zoo tib yam resin, qhov chaw cia kub yog qhov zoo tshaj plaws nyob rau hauv lub cheeb tsam tam sim no kub ntawm 25 degrees Celsius.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 lub caij nplooj zeeg ntawm txawv teb chaws impurities.Thiab lub hau ntawm lub ntim ntim rau khaws cov resin tsis tuaj yeem ua los ntawm tooj liab lossis tooj liab alloy, thiab nws yog qhov zoo tshaj plaws los siv polyethylene, polyvinyl chloride thiab lwm yam hlau hau.
Feem ntau hais lus, nyob rau hauv cov ntaub ntawv ntawm kub siab, nws yog txaus kom tsis txhob ncaj qha tshav ntuj mus rau lub ntim ntim.Txawm li cas los xij, lub txee lub neej tseem yuav cuam tshuam, vim tias nyob rau hauv huab cua kub, lub sij hawm gel ntawm cov resin yuav luv luv ntau, thiab yog tias cov resin tsis zoo, nws yuav raug kho ncaj qha rau hauv lub ntim 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 ua tib zoo saib xyuas lub sijhawm khaws cia ntawm cov resin.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov resins tov nrog styrene yuav tsum tau kho raws li flammable hydrocarbons los tiv thaiv hluav taws.Lub tsev khaws khoom thiab chaw ua haujlwm uas khaws cov resins yuav tsum muaj kev tswj xyuas nruj heev, thiab ua haujlwm zoo ntawm kev tiv thaiv hluav taws thiab tiv thaiv hluav taws txhua lub sijhawm.
Cov teeb meem kev nyab xeeb uas yuav tsum tau them nyiaj rau thaum lub sij hawm ua cov saturated polyester resin nyob rau hauv lub rhiav
1. Resin, curing agent thiab accelerator yog txhua yam khoom siv hluav taws xob, thiab yuav tsum tau them nyiaj rau kev tiv thaiv hluav taws.Qee cov accelerators thiab resins yuav tsum tau muab cais tawm, txwv tsis pub nws yooj yim 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 pa hauv qhov chaw ua haujlwm.Ib qho yog los tswj cov huab cua sab hauv tsev kom cov volatiles ntawm styrene tuaj yeem raug tshem tawm txhua lub sijhawm.Vim tias styrene vapor yog denser dua huab cua, qhov concentration ntawm styrene nyob ze hauv av kuj tseem siab.Yog li ntawd, nws yog qhov zoo tshaj plaws los teeb lub qhov hluav taws xob cua hauv chav ua haujlwm ze rau hauv av.Lwm qhov yog ua kom lub hauv paus tso tawm qhov chaw ua haujlwm nrog kev pab ntawm cov cuab yeej thiab cov khoom siv.Piv txwv li, ib lub kiv cua cais tawm tau teeb tsa kom tshem tawm cov siab-concentration styrene vapor tawm ntawm qhov chaw ua haujlwm, lossis cov pa roj flue tau tag nrho los ntawm cov yeeb nkab nqus dej dav dav hauv chav ua haujlwm.
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, thiab 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 muab xa mus rau qhov chaw ruaj ntseg rau dispersed cia, thiaj li tiv thaiv kom tsis txhob muaj cua kub ntau los ntawm tsub zuj zuj thiab ua rau tawg thiab hluav taws kub.
7. Thaum tsis muaj cov polyester resin xau, nws yuav ua rau hluav taws kub, thiab cov pa phem yuav raug tso tawm thaum lub sijhawm ua haujlwm no, uas yuav ua rau tib neeg noj qab haus huv.Yog li ntawd, kev ntsuas kub ceev yuav tsum tau ua los daws nws.
