nkhani

Kutentha ndi kuwala kwa dzuwa zimatha kukhudza nthawi yosungira ma polyester resins osakhuta. Ndipotu, kaya ndi polyester resins yosakhuta kapena utomoni wamba, kutentha kosungirako ndikobwino kwambiri pa kutentha kwa dera komwe kulipo kwa madigiri 25 Celsius. Pachifukwa ichi, kutentha kotsika, nthawi yogwira ntchito ya polyester resins yosakhuta imakhala yayitali; kutentha kokwera, nthawi yogwira ntchito imakhala yochepa.
Utomoni uyenera kutsekedwa ndikusungidwa mu chidebe choyambirira kuti uteteze kuwonongeka kwa monomer komanso kugwa kwa zinyalala zakunja. Ndipo chivindikiro cha mbiya yosungiramo utomoni sichingapangidwe ndi mkuwa kapena aloyi wamkuwa, ndipo ndibwino kugwiritsa ntchito polyethylene, polyvinyl chloride ndi zivundikiro zina zachitsulo.
Kawirikawiri, pakakhala kutentha kwambiri, ndikokwanira kupewa kuwala kwa dzuwa mwachindunji ku mbiya yosungiramo zinthu. Komabe, nthawi yosungiramo zinthu idzakhudzidwabe, chifukwa kutentha kwambiri, nthawi ya gel ya utomoni idzafupikitsidwa kwambiri, ndipo ngati utomoni uli woipa, udzathiridwa mwachindunji mu mbiya yosungiramo zinthu.
Chifukwa chake, panthawi yotentha kwambiri, ngati zinthu zilola, ndi bwino kuisunga m'nyumba yosungiramo zinthu zoziziritsa mpweya zomwe kutentha kwake kumakhala kofanana ndi madigiri 25 Celsius. Ngati wopanga sakukonzekera nyumba yosungiramo zinthu zoziziritsa mpweya, ayenera kusamala kuti nthawi yosungiramo utomoniyo ichepe.

Ndikofunikira kudziwa kuti ma resin osakanikirana ndi styrene ayenera kuonedwa ngati ma hydrocarbon oyaka moto kuti apewe moto. Malo osungiramo zinthu ndi malo ogwirira ntchito omwe amasungira ma resin awa ayenera kuyang'aniridwa mosamala kwambiri, ndikuchita bwino ntchito yoletsa moto komanso kupewa moto nthawi iliyonse.

Nkhani zachitetezo zomwe ziyenera kuganiziridwa pokonza utomoni wa polyester wokhuta mu workshop
1. Utomoni, chothandizira kuchiritsa ndi chofulumizitsa moto zonse ndi zinthu zomwe zimatha kuyaka, ndipo chisamaliro chiyenera kuperekedwa popewa moto. Ma accelerator ndi ma resin ena ayenera 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 wokwanira mu malo opangira mpweya. Choyamba ndi kusunga mpweya wozungulira mkati mwa nyumba kuti mpweya woipa wa styrene uchotsedwe nthawi iliyonse. Chifukwa nthunzi ya styrene ndi yokhuthala kuposa mpweya, kuchuluka kwa styrene pafupi ndi nthaka nakonso kumakhala kwakukulu. Chifukwa chake, ndi bwino kuyika malo otulutsira mpweya mu malo opangira mpweya pafupi ndi nthaka. China ndi kutulutsa mpweya m'deralo pogwiritsa ntchito zida ndi zida. Mwachitsanzo, fani yosiyana yotulutsa mpweya imayikidwa kuti ichotse nthunzi ya styrene yokhuthala kwambiri yomwe imatuluka m'dera lopangira mpweya, kapena mpweya wotuluka umachotsedwa kudzera mu chitoliro choyamwa chomwe chili mu malo opangira mpweya.
4. Pofuna kuthana ndi zochitika zosayembekezereka, malo opangira zinthu ayenera kukhala ndi njira ziwiri zotulukira.
5. Utomoni ndi zothamangitsa zosiyanasiyana zomwe zimasungidwa mu workshop yopangira siziyenera kukhala zambiri, ndipo ndibwino kusunga pang'ono.

6. Ma resin omwe sanagwiritsidwe ntchito koma awonjezeredwa ndi ma accelerator ayenera kusamutsidwira kumalo otetezeka kuti asungidwe mosakanikirana, kuti kutentha kwakukulu kusasonkhanitsidwe ndikuyambitsa kuphulika ndi moto.
7. Utomoni wa polyester wosakhuta ukatuluka, umayambitsa moto, ndipo mpweya woipa udzatuluka panthawiyi, zomwe zidzaika thanzi la anthu pachiwopsezo. Chifukwa chake, njira zadzidzidzi ziyenera kutengedwa kuti zithetsedwe.
