Ama-polyester polymer chips afana ne-PET athambile futhi amunca umswakama ovela emoyeni ozungezile. Umswakama omningi kuma-chips ungabangela izinkinga ngesikhathi sokubumba nokukhipha umjovo. Uma ipulasitiki ishiswa, amanzi aqukethe akhipha i-PET, okunciphisa amandla ayo kanye nekhwalithi yayo. Kusho ukususa umswakama omningi ngangokunokwenzeka ku-resin ngaphambi kokucubungula i-PET emshinini wokubumba. Ngaphansi kwezimo zomoya, ama-resin angase abe namanzi afinyelela ku-0.6%.
Ngakho-ke ukomisa kwe-PET kanjani ukuze kulinganiswe umswakama?
Lapha sibala Amathiphu Amabili Okufanele Uqaphele Uma Uyomisa Izilwane Ezifuywayo Ukuze Ulinganise Umswakama.
Ama-Pellet e-PET ayomiswa ngaphambi kokucutshungulwa
Ama-chip okhuni afakwa kwi-hopper, bese umoya oshisayo, owomile onezinga lokushisa lamazolo elingama-50°C uphonswa phansi kwe-hopper, bese ugeleza phezulu phezu kwama-pellets, ususe noma yimuphi umswakama endleleni. Umoya oshisayo ushiya ingxenye ephezulu ye-hopper bese udlula kuqala endaweni epholile, njengoba umoya obandayo ususa umswakama kalula kunomoya oshisayo. Umoya obandayo, omanzi ophumayo ube usudlula embhedeni we-desiccant. Ekugcineni, umoya obandayo, owomile ophuma embhedeni we-desiccant ufudunyezwa kabusha ku-process heater bese uthunyelwa emuva ngenqubo efanayo ku-loop evaliwe. Okuqukethwe komswakama kwama-chip kumele kube ngaphansi kwama-30 ppm ngaphambi kokucubungula. Lapho i-PET ishiswa, noma yimaphi amanzi akhona azofaka i-polymer ngokushesha, anciphise isisindo sayo sama-molecule futhi abhubhise izakhiwo zayo zomzimba.
Ukulinganisa Okuku-inthanethi Nokuhlola Okuqondile
Kunezindlela ezimbili zokulinganisa umswakama ngesikhathi sokomisa: ukulinganisa online kanye nokuhlola indawo.
① ukulinganisa okuku-inthanethi
Ama-dryer ngamanye aqashwe njalo ukuqinisekisa ukuthi ukuphakelwa komoya kwi-PET kungcono kunomkhawulo wokushisa we-dew point ongu-50°C dew point ukuqinisekisa ukuthi izinto ze-chip zomile ngempumelelo. Lapho kudingeka khona izilinganiso eziqondile ngokulinganisa kwangaphakathi okuzenzakalelayo, ungayifakaInzwa ye-HT-608 dew pointeduze kokungena kwe-drying hopper, futhi usayizi wayo omncane kanye nokukhanya kwayo kwenza kube lula ukuyifaka emipayipini noma ezindaweni eziqinile ukuhlola ukuvuza endleleni yomoya womshini wokomisa. Ukunemba okuphezulu ±0.2 ° C (5-60 ° C Td), okuqhathaniswa nekhwalithi yemikhiqizo engenisiwe, okungabizi, kuyindlela engcono kakhulu engabizi.
② Hlola bese ulinganisa
Ukuhlola njalo indawo noHengkoImitha yokushisa nomswakama ephathekayo ye-HK-J8A102Imitha yokushisa nomswakama elinganisiwe ephathekayo ye-c inganikeza isiqinisekiso sekhwalithi yomkhiqizo esonga izindleko. Kulula ukuyisebenzisa, ilinganisa izinga lokushisa ngasikhathi sinye, umswakama, iphuzu lamazolo, isibani esimanzi, kanye neminye imininingwane. Phendula ngokushesha ezindaweni zamazolo ezijwayelekile zezimboni ezingaphansi kwama-50℃.
Ibanga lokulinganisa iphuzu lamazolo lemitha yokushisa nomswakama lingu-50℃-60℃, futhi isikrini esikhulu se-LCD silungele ukufunda nokufunda. Idatha yokulinganisa ibalwa kanye njalo ngemizuzwana eyi-10, futhi isivinini sokuphendula siyazwela, futhi ukulinganisa kunembile.
Usenemibuzo futhi ungathanda ukwazi imininingwane eyengeziwe mayelana nokuqapha umswakama ngaphansi kwezimo zezulu ezimbi, sicela ukhululeke ukuxhumana nathi manje.
