Kodi Kuumitsa kwa PET Kumayesa Bwanji Chinyezi?

Ma chips a polyester polymer monga PET ndi a hygroscopic ndipo amayamwa chinyezi kuchokera mumlengalenga wozungulira. Chinyezi chochuluka mu ma chips chingayambitse mavuto panthawi yopangira jakisoni ndi kutulutsa. Pulasitiki ikatenthedwa, madzi omwe ali mkati mwake amathira PET, zomwe zimachepetsa mphamvu ndi ubwino wake. Zimatanthauza kuchotsa chinyezi chochuluka momwe zingathere mu utomoni musanagwiritse ntchito PET mu makina opangira. Mu nyengo ya mlengalenga, ma resin amatha kukhala ndi madzi okwana 0.6%.

Ndiye Kodi Kuumitsa kwa PET Kumayesa Bwanji Chinyezi?

Apa tikulemba malangizo awiri omwe muyenera kuwasamala mukamawumitsa PET kuti muyese chinyezi.

Ma Pellets a PET Amaumitsidwa Asanakonzedwe

Zidutswa zamatabwa zimayikidwa mu hopper, kenako mpweya wotentha, wouma wokhala ndi kutentha kwa mame pafupifupi 50°C umapopedwa pansi pa hopper, ndipo umapita mmwamba pamwamba pa ma pellets, kuchotsa chinyezi chilichonse m'njira. Mpweya wotentha umachoka pamwamba pa hopper ndikudutsa kaye mu cooler, chifukwa mpweya wozizira umachotsa chinyezi mosavuta kuposa mpweya wotentha. Mpweya wozizira, wonyowa womwe umabwera umadutsa mu desiccant bed. Pomaliza, mpweya wozizira, wouma womwe umachoka mu desiccant bed umatenthedwanso mu process heater ndikutumizidwanso kudzera mu njira yomweyo mu closed loop. Chinyezi cha ma chips chiyenera kukhala chochepera 30 ppm musanachigwiritse ntchito. PET ikatenthedwa, madzi aliwonse omwe alipo adzasungunuka mwachangu polima, kuchepetsa kulemera kwake kwa mamolekyu ndikuwononga mawonekedwe ake enieni.

Kuyeza Pa intaneti ndi Kufufuza Malo

Pali njira ziwiri zoyezera chinyezi pouma: kuyeza pa intaneti ndi kuyang'ana malo.

① muyeso wa pa intaneti

Zipangizo zowumitsira mpweya payekhapayekha zimayang'aniridwa nthawi zonse kuti zitsimikizire kuti mpweya wopita ku PET ndi wabwino kuposa malire a kutentha kwa mame omwe adatchulidwa a 50°C dema point kuti zitsimikizire kuti zinthu za chip zauma bwino. Ngati pakufunika kuyeza molondola pogwiritsa ntchito njira yodziwikiratu yamkati, mutha kukhazikitsaSensa ya HT-608 dew pointpafupi ndi malo olowera a choumitsira, ndipo kukula kwake kochepa komanso kopepuka kumapangitsa kuti zikhale zosavuta kuyika m'mapayipi kapena m'malo opapatiza kuti muwone ngati pali kutuluka kwa mpweya munjira ya choumitsira. Kulondola kwambiri ±0.2 ° C (5-60 ° C Td), kofanana ndi khalidwe la zinthu zotumizidwa kunja, kotsika mtengo, ndi njira ina yotsika mtengo.

② Yang'anani ndi kulinganiza bwino

Kufufuza nthawi zonse ndi HengkoHK-J8A102 mita yoyendera kutentha ndi chinyeziChoyezera kutentha ndi chinyezi chonyamulika chonyamulika bwino chingapereke chitsimikizo cha khalidwe la chinthucho chotsika mtengo. N'chosavuta kugwiritsa ntchito, poyesa kutentha, chinyezi, mame, babu lonyowa, ndi zina zambiri. Yankhani mwachangu ku mame omwe ali pansi pa 50℃.

Mulingo woyezera kutentha ndi chinyezi wa dew point wa mita ya kutentha ndi chinyezi ndi -50℃-60℃, ndipo chophimba chachikulu cha LCD ndi chosavuta kuwerenga ndi kuwerenga. Deta yoyezera imawerengedwa kamodzi pa mamilisekondi 10 aliwonse, ndipo liwiro loyankha ndi losavuta, ndipo muyeso ndi wolondola.

Muli ndi Mafunso Okhudza Kuwunika Chinyezi Mu Nyengo Yaikulu, Chonde Osazengereza Kulumikizana Nafe Tsopano.
