Kutentha ndi kuwala kwa dzuwa kungakhudze nthawi yosungiramo unsaturated polyester resins.M'malo mwake, kaya ndi unsaturated polyester resin kapena utomoni wamba, kutentha kosungirako ndikwabwino kwambiri pakutentha kwapano kwa 25 digiri Celsius.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 muteteze kutayika kwa monomer volatilization ndi kugwa kwa zonyansa zakunja.Ndipo chivindikiro cha mbiya yosungiramo utomoni sichingapangidwe ndi mkuwa kapena aloyi yamkuwa, ndipo ndi bwino kugwiritsa ntchito polyethylene, polyvinyl chloride ndi zitsulo zina zachitsulo.
Nthawi zambiri, pakakhala kutentha kwakukulu, ndikokwanira kupewa kuwala kwa dzuwa ku mbiya yopangira.Komabe, moyo wa alumali udzakhudzidwabe, chifukwa nyengo yotentha kwambiri, nthawi ya gel ya utomoni imafupikitsidwa kwambiri, ndipo ngati utomoni ulibe khalidwe labwino, ukhoza kuchiritsidwa 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 kusungidwa ngati ma hydrocarbon oyaka moto kuteteza moto.Malo osungiramo katundu ndi ma workshop omwe amasungira ma resin awa ayenera kukhala ndi kasamalidwe kokhwima kwambiri, ndikuchita ntchito yabwino yopewera moto ndi kupewa moto nthawi iliyonse.

Nkhani zachitetezo zomwe ziyenera kutsatiridwa pakukonza utomoni wa polyester wodzaza mumsonkhanowu
1. Utoto, wochiritsa ndi accelerator zonse ndi zida zoyaka moto, ndipo chidwi chiyenera kuperekedwa pakupewa moto.Ma accelerators ena ndi ma resins ayenera 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 mu msonkhanowu.Chimodzi ndicho kusunga mpweya wamkati m'nyumba kotero kuti styrene akhoza kuchotsedwa nthawi iliyonse.Chifukwa mpweya wa styrene ndi wandiweyani kuposa mpweya, kuchuluka kwa styrene pafupi ndi nthaka ndikwambiri.Choncho, ndi bwino kukhazikitsa mpweya wotuluka mu msonkhano pafupi ndi pansi.Wina ndikuchotsa malo ogwirira ntchito mothandizidwa ndi zida ndi zida.Mwachitsanzo, chotenthetsera chopopera chosiyana chimakhazikitsidwa kuti chichotse mpweya wokwera kwambiri wa styrene womwe umatulutsidwa pamalo opangira opaleshoni, kapena mpweya wa flue utha kudzera mutoliro loyamwa wamba lomwe lakhazikitsidwa mu msonkhano.
4. Kuti muthane ndi zochitika zosayembekezereka, msonkhano wopanga uyenera kukhala ndi zotuluka zosachepera ziwiri.
5. Utomoni ndi ma accelerators osiyanasiyana omwe amasungidwa mumsonkhano wopanga sayenera kukhala wochuluka, ndipo ndi bwino kusunga pang'ono.

6. Ma resin omwe sanagwiritsidwe ntchito koma awonjezeredwa ndi ma accelerator ayenera kusamutsidwa kumalo otetezeka kuti asungidwe omwazika, kuti ateteze kutentha kwakukulu kuti zisawunjike ndikuyambitsa kuphulika ndi moto.
7. Unsaturated polyester resin ikatuluka, imayambitsa moto, ndipo mpweya wapoizoni udzatulutsidwa panthawiyi, zomwe zingawononge thanzi laumunthu.Choncho, njira zadzidzidzi ziyenera kuchitidwa kuti zithetse.
