Kutentha ndi kuwala kwa dzuwa zimakhudza nthawi yosungira polyester resin yosakhuta. Ndipotu, kaya ndi polyester resin yosakhuta kapena ma resin ena, kutentha kosungirako kumakhala madigiri 25 Celsius m'dera lomwe lilipo. Pachifukwa ichi, kutentha kotsika, nthawi yogwira ntchito ya polyester resin yosakhuta imakhala yayitali; kutentha kokwera, nthawi yogwira ntchito imakhala yochepa.
Utomoni uyenera kutsekedwa ndikusungidwa mu chidebe choyambirira kuti uteteze kuwonongeka kwa monomer komanso kutsika kwa zinyalala zakunja. Ndipo chivindikiro cha mbiya yosungiramo utomoni sichiyenera kupangidwa ndi mkuwa kapena aloyi wamkuwa, makamaka polyethylene, polyvinyl chloride ndi zivindikiro zina zachitsulo.
Kawirikawiri, kutentha kwambiri, pewani kuwala kwa dzuwa mwachindunji ku mbiya yolongedza, koma nthawi yosungira idzakhudzidwabe, chifukwa kutentha kwambiri, nthawi ya gel ya utomoni idzafupikitsidwa kwambiri, ngati ndi utomoni wosauka, ngakhale idzauma mwachindunji mu mbiya yolongedza. Chifukwa chake, panthawi yotentha kwambiri, ngati zinthu zilola, ndibwino kuisunga m'nyumba yosungiramo zinthu zowongolera mpweya yokhala ndi kutentha kosalekeza kwa madigiri 25 Celsius. Ngati wopanga sakukonzekera nyumba yosungiramo zinthu zowongolera mpweya, ayenera kusamala kuti nthawi yosungiramo utomoni ifupikitsidwe.
Ndikofunikira kudziwa kuti utomoni wosakaniza ndi styrene uyenera kuonedwa ngati ma hydrocarbon oyaka moto kuti upewe moto. Payenera kukhala kuyang'anira mosamala kwambiri malo osungiramo zinthu ndi zomera zomwe zimasunga utomoni wamtunduwu, ndipo ntchito yoletsa moto ndi kuyaka iyenera kuchitika nthawi zonse.
Nkhani zachitetezo zomwe ziyenera kuganiziridwa pokonza utomoni wa polyester wosakhuta m'malo ogwirira ntchito
1. Utomoni, chothandizira kuchiritsa, ndi chofulumizitsa moto zonse ndi zinthu zomwe zimatha kuyaka, kotero kupewa moto kuyenera kusamalidwa, ndipo ziyenera kusungidwa padera, apo ayi zimakhala zosavuta kuyambitsa kuphulika.
2. Sipayenera kukhala kusuta fodya kapena malawi otseguka pa malo opangira zinthu.
3. Malo opangira mpweya ayenera kukhala ndi mpweya wokwanira. Pali mitundu iwiri ya mpweya wolowera m'malo opangira mpweya, imodzi ndi kusunga mpweya woyenda m'nyumba, kuti muchotse styrene yosasunthika nthawi iliyonse. Popeza nthunzi ya styrene ndi yokhuthala kuposa mpweya, kuchuluka kwa styrene pafupi ndi nthaka nakonso kumakhala kwakukulu. Chifukwa chake, mpweya wotuluka m'malo opangira mpweya uyenera kuyikidwa pafupi ndi nthaka. Ina ndikugwiritsa ntchito zida ndi zida zotulutsira mpweya m'malo opangira mpweya. Mwachitsanzo, ikani fani yosiyana yotulutsira mpweya kuti mutulutse nthunzi ya styrene yokhuthala kwambiri kuchokera pamalo opangira mpweya, kapena kutulutsa mpweya wotuluka kudzera mu chitoliro chachikulu chokoka mpweya chomwe chili mu malo opangira mpweya.
4. Pofuna kuthana ndi zochitika zosayembekezereka, malo opangira zinthu ayenera kukhala ndi njira zotulukira ziwiri kapena kuposerapo.
5. Utomoni ndi zothamangitsa zosiyanasiyana zomwe zimasungidwa mu workshop yopangira siziyenera kukhala zambiri, ndibwino kusunga pang'ono.
6. Ma resini omwe sanagwiritsidwe ntchito koma awonjezedwa ndi ma accelerator ayenera kusamutsidwira kumalo otetezeka ndikusungidwa padera kuti kutentha kwakukulu kusasonkhanitsidwe ndikuyambitsa kuphulika ndi moto.
7. Utomoni wa polyester wosakhuta ukangotuluka ndikuyambitsa moto, mpweya woipa umatuluka panthawiyi ndikuika thanzi la anthu pachiwopsezo. Chifukwa chake, njira zadzidzidzi ziyenera kutengedwa kuti zithetsedwe.
