Kodi PU Foam Technology Pamipando Yagalimoto Ndi Yotani?

1. Kusiyanitsa ndi kutentha kwa nkhungu

1)Kutentha kwa thovu:

Pambuyo pomaliza, nkhungu imayikidwa mu uvuni pa madigiri 220-250℃(osachepera 180℃), ndipo zochitazo zikamalizidwa, zimachotsedwa ndikuzigwetsa.

Ubwino: kachulukidwe kakang'ono ka thovu, kukalamba kwabwino kwa kutentha, osafunikira mipata yosiyana.Mtengo wa nkhungu ndi wotsika.

Zoipa: kugwiritsa ntchito mphamvu zambiri.Bowo lotulutsa mpweya ndi losavuta kupanga "mutu wa bowa", zomwe zimapangitsa kuti zinthu zambiri ziwonongeke.Pambuyo pake kuyeretsa pamalo ndi kukonza zida kumakhala kovuta kwambiri.

2)Kuzizira kutulutsa thovu

Nthawi zambiri amapangidwa ngati amultistation turntable line kupanga.Nthawi zambiri nkhungu imatenthedwa mpaka 45-70℃ndi makina otenthetsera nkhungu, kenako ndikugwetsedwa pambuyo pakuchita thovu kumalizidwa ndikutsanulira zinthu za PU.Pambuyo pobowola, chinthucho chimayenera kugwiritsa ntchito chopukutira thovu kuti chithandizire kutsegula dzenje.Ubwino: Kugwiritsa ntchito mphamvu zochepa, zida zoyera komanso kukonza kosavuta Zoyipa: Zidazi ndizovuta komanso mtengo wake ndi wokwera.Kuchita kwa thovu thermalization ndi avareji.

2. Kusiyanitsa ndi kutsatsa pamwamba

1) Chithovu chamaliseche:

Amatchulidwa mosiyana ndi lingaliro la kutsatsa ndi kutulutsa thovu, nsaluyo sidzayikidwa kale mu nkhungu, ndipo pamwamba pa chinthu chopangidwa ndi thovu ndi PU wosanjikiza.Zakudyazi zonse zimasonkhanitsidwa pambuyo pokonza.Magalimoto okwera nthawi zambiri amagwiritsa ntchito njira yotulutsa thovu.

2) Adsorption thovu

Musanatsanulire, choyamba ikani nsalu mu nkhungu, ipangitseni kuti ikhale yoyenera ndi kuyamwa ndi kutsekemera, kenaka tsanulirani za PU.Pambuyo pochita thovu, pamwamba pa chinthu chopangidwa ndi PU chimamangiriridwa mwamphamvu pansaluyo.Mipando yamakina omanga ndiyotheka kugwiritsa ntchito njira yotulutsa thovu iyi.

3. Kusiyanitsa ndi kuuma

1) Chithovu cholimba chimodzi:

Ndilo thovu losavuta kwambiri, chilinganizo chimodzi, kuthira kamodzi, palibe njira ina yothandizira, ndipo zopangidwa ndi thovu zomwe zimaperekedwa zimakhala ndi kuuma kumodzi kokha.

2) Chithovu cholimba kawiri

Chithovu cholimba kawiri ndiye malo ogulitsa magalimoto ambiri apamwamba.Malo okwera ndi ofewa, ndipo madera othandizira mbali zonse ndi ovuta, omwe angapereke chitonthozo chochuluka.Njira yokwaniritsira izi ndikugwiritsa ntchito malo okhalamo ndi mbali ziwiri za malowo kutsanulira padera, ndikukwaniritsa kuuma kwapawiri kapena kuuma kosiyanasiyana kwa chinthucho poyika nkhungu pamakona, ndikuwonjezera nkhonya pakati pa mapiko awiri ndi malo okhala, ndikuwonjezera zoyikapo mbali zonse za thovu..Njira yotulutsa thovu iyi imathanso kukwaniritsa zovuta zitatu, koma osati zambiri.M'makampani, amatchedwanso thovu lawiri-kachulukidwe, komwe kwenikweni kumakhala kutsetsereka kwa lilime.Cholinga cha ndondomekoyi ndikupeza kuuma kosiyana, osati kachulukidwe.Ndipo nthawi zina kachulukidwe kamodzi kamatha kupanga zovuta ziwiri zosiyana.Opanga omwe amadziwa bwino ntchito yotulutsa thovuyi nthawi zambiri amafunika kukhala ndi akatswiri omwe ali ndi luso losintha zinthu zophatikizira, chifukwa amafunika kudziwa bwino kusintha ndikusintha kwamitundu ingapo.
