Kub thiab tshav ntuj yuav cuam tshuam rau lub sijhawm khaws cia ntawm cov khoom lag luam tsis tau. Qhov tseeb, txawm hais tias nws tsis tau txais nyiaj rov qab polyester tsis tau lossis lwm yam Resins, qhov chaw cia kub yog qhov zoo dua 25 degrees Celsius nyob hauv thaj chaw tam sim no. Ntawm lub hauv paus no, qis dua qhov kub thiab txias, lub sijhawm siv tau ntev dua ntawm cov khoom lag luam polyester unsaturated; Qhov siab dua qhov ntsuas kub, luv luv ntawm lub sijhawm siv tau.
Lub chaw cob qhia yuav tsum tau muab ntim thiab khaws cia rau hauv lub thawv qub los tiv thaiv kom tsis txhob muaj kev poob ntawm monomer volatilization thiab poob ntawm sab nraud impurities. Thiab lub hau ntawm cov ntim thoob khib nyiab rau khaws cia tooj liab lossis tooj liab alloy, nyiam dua polyethylene, polyvinyl chloride thiab lwm lub hau hlau.
Feem ntau hais lus, nyob rau hauv cov kev mob siab, zam kev ua lub hnub ci rau lub thawv ntim, vim tias nws yog qhov ua tau zoo dua qub, txawm tias yuav solutify tsis zoo hauv lub ntim ntim. Yog li ntawd, thaum lub sijhawm kub lub sijhawm kub, yog tias muaj kev tso cai khaws cia, nws yog qhov zoo tshaj plaws los khaws nws hauv cov chaw ua haujlwm cua txias nrog kub tas li ntawm 25 degrees Celsius. Yog tias cov chaw tsim khoom tsis npaj lub tsev rau khoom cua txias, nws yuav tsum xyuam xim kom luv luv lub sijhawm khaws cia ntawm lub resin.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov fij cov khoom cob nrog styrene yuav tsum tau kho kom zoo li cov pa hluav taws kub kom tiv thaiv kom tiv thaiv hluav taws. Yuav tsum muaj kev tswj hwm nruj heev thiab nroj tsuag uas khaws cov ntawv cob sia, thiab kev tiv thaiv hluav taws thiab kev sib txuas ua ke txhua lub sijhawm.
Kev Nyab Xeeb Kev Nyab Xeeb Uas Yuav Tsum Tau Them Siab rau thaum lub sijhawm ua haujlwm ntawm cov khoom lag luam tsis txaus ntseeg hauv qhov chaw ua haujlwm
1. Resin, tus neeg kho tus neeg sawv cev, thiab cov neeg muag khoom thiab cov khoom siv hluav taws xob, yog tias lawv yuav tsum tau them rau kev sib cais, thiab lawv yuav tsum tau ua kom zoo rau, thiab lawv yuav tsum tau ua kom zoo rau, thiab lawv yuav tsum tau ua kom yooj yim rau kev tawg.
2. Yuav tsis muaj kev haus luam yeeb thiab tsis qhib cov nplaim taws hauv kev ua haujlwm ntau lawm.
3. Qhov kev sib txuas ntau ntau yuav tsum muaj qhov cua muaj peev xwm kom txaus. Muaj ob daim ntawv cua sov, ib qho yog tswj cov huab cua hauv sab hauv, yog li kom tshem tawm cov volatile styrene nyob rau txhua lub sijhawm. Vim tias vapor yog denser tshaj li huab cua, qhov kev txiav txim siab STYRENE ze rau hauv av kuj tseem muaj siab. Yog li ntawd, qhov tso pa tawm hauv chav ua haujlwm yog qhov zoo tshaj plaws tau teeb tsa ze rau hauv av. Lwm tus yog siv cov cuab yeej thiab cov cuab yeej siv rau cov khoom siv hauv cheeb tsam ua haujlwm. Piv txwv li, teeb tsa lwm tus ntxauv ntxuam ntxaij kom rho tawm cov pa roj, lossis tso pa hluav taws xob nrog cov pa hluav taws xob tseem ceeb tau raug ntsia hauv lub rhiav.
4. Txhawm rau daws cov xwm txheej uas tsis tau npaj txhij txog, kev tsim khoom yuav tsum muaj tsawg kawg yog ob qhov tawm.
5. Lub Resin thiab ntau yam kev ceev ceev cia hauv kev ua haujlwm ntau lawm hauv kev tsim khoom lag luam yuav tsum tsis txhob ntau, nws yog qhov zoo tshaj plaws los khaws cov nyiaj me me.
6. Resins uas tsis tau siv tab sis tau ntxiv nrog cov nrawm dua yuav tsum tau muab cais kom tiv thaiv kom muaj kev nyab xeeb thiab ua rau tawg thiab hluav taws.
7. Ib zaug qhov tsis txaus ntseeg polyester resin quain thiab ua rau hluav taws, cov roj lom, cov roj ntsha yuav raug rho tawm hauv tib neeg kev noj qab haus huv. Yog li no, kev ntsuas kub ntxhov yuav tsum tau coj mus nrog nws.
