Kutentha ndi kuwala kwa dzuwa kudzakhudza nthawi yosungiramo unsaturated polyester resin.M'malo mwake, kaya ndi unsaturated polyester resin kapena ma resins ena, kutentha kosungirako ndikoyenera kukhala madigiri 25 Celsius m'dera lapano.Pazifukwa izi, kutsika kwa kutentha, kumakhala nthawi yayitali yovomerezeka ya unsaturated polyester resin;kutentha kwapamwamba, kumachepetsa nthawi yovomerezeka.
Utoto uyenera kusindikizidwa ndikusungidwa mu chidebe choyambirira kuti uteteze kutayika kwa monomer volatilization ndi kugwa kwa zonyansa zakunja.Ndipo chivindikiro cha mbiya yosungiramo utomoni sayenera kupangidwa ndi mkuwa kapena aloyi yamkuwa, makamaka polyethylene, polyvinyl chloride ndi zitsulo zina zazitsulo.
Nthawi zambiri, pakatentha kwambiri, pewani kuwala kwadzuwa ku mbiya yoyikamo, koma nthawi yosungirako idzakhudzidwabe, chifukwa nyengo yotentha kwambiri, nthawi ya gel ya utomoni imafupikitsidwa kwambiri, ngati ndi utomoni wabwino kwambiri. , ngakhale Adzalimbitsa mwachindunji mu mbiya yonyamula.Choncho, panthawi yotentha kwambiri, ngati mikhalidwe ikuloleza, ndi bwino kuisunga m'nyumba yosungiramo mpweya wokhala ndi kutentha kosalekeza kwa madigiri 25 Celsius.Ngati wopanga sakukonzekera nyumba yosungiramo mpweya, iyenera kumvetsera kufupikitsa nthawi yosungiramo utomoni.
Ndikofunikira kudziwa kuti utomoni wosakanikirana ndi styrene uyenera kutengedwa ngati ma hydrocarbon oyaka moto kuteteza moto.Payenera kukhala kasamalidwe kokhwima kosungiramo katundu ndi zomera zomwe zimasunga utomoni woterewu, ndipo ntchito yoletsa moto ndi kuyaka iyenera kuchitika nthawi zonse.
Nkhani zachitetezo zomwe ziyenera kutsatiridwa pakukonza unsaturated polyester resin mumsonkhanowu
1. Utomoni, wochiritsa, ndi accelerator zonse ndi zinthu zoyaka moto, choncho kupewa moto kuyenera kulipidwa, ndipo ziyenera kusungidwa padera, apo ayi ndizosavuta kuyambitsa kuphulika.
2. Pasakhale kusuta komanso moto wotseguka pamisonkhano yopanga.
3. Malo ochitira msonkhanowo ayenera kukhala ndi mpweya wokwanira.Pali mitundu iwiri ya mpweya wabwino wa msonkhano, imodzi ndiyo kusunga mpweya wamkati, kuti muchotse styrene yosakhazikika nthawi iliyonse.Chifukwa mpweya wa styrene ndi wandiweyani kuposa mpweya, styrene yomwe ili pafupi ndi nthaka imakhala yokwera kwambiri.Choncho, mpweya wotulutsa mpweya mumsonkhanowu umayikidwa bwino pafupi ndi nthaka.Chinanso ndikugwiritsa ntchito zida ndi zida kuti zithere malo ogwirira ntchito.Mwachitsanzo, khazikitsani chotenthetsera chosiyana kuti muchotse mpweya wochuluka wa styrene pamalo opangira opaleshoni, kapena kutulutsa mpweya wa flue kudzera papaipi yayikulu yoyamwa yomwe imayikidwa mumsonkhanowu.
4. Kuti muthane ndi zochitika zosayembekezereka, msonkhano wopanga uyenera kukhala ndi zotuluka zosachepera ziwiri.
5. Utomoni ndi ma accelerators osiyanasiyana omwe amasungidwa mumsonkhano wopangira sayenera kukhala wochuluka, ndi bwino kusunga pang'ono.
6. Ma resins omwe sanagwiritsidwe ntchito koma awonjezeredwa ndi ma accelerator ayenera kusamutsidwa kumalo otetezeka ndi kusungidwa padera kuti ateteze kutentha kwakukulu kuti zisawunjike pakusonkhanitsa ndikuyambitsa kuphulika ndi moto.
7. Utoto wa poliyesitala wosatulutsidwa ukangotuluka ndikuyambitsa moto, mipweya yapoizoni imatulutsidwa panthawiyi ndikuyika thanzi la anthu pachiwopsezo.Choncho, njira zadzidzidzi ziyenera kuchitidwa kuti zithetse.
