Yiziphi izinto okufanele zenziwe nezingafaneleki ngezifutho ze-polyurethane?I-polyurethane sprayer ingumshini okhethekile wokugcoba usebenzisa ubuchwepheshe bokufafaza.Umgomo uwukusheshisa ukushintshwa kwedivayisi yokuqondisa umoya ukuze injini ye-pneumatic isebenze ngokushesha futhi i-piston ibe ukunyakaza okuphindaphindayo nokuqhubekayo.

Ukuze kwandiswe umthamo we-urethane, i-urethane ilethwa kusibhamu sokufuthwa sesifafazi ngepayipi elinomfutho ophezulu, lapho impahla ifuthwa khona manjalo ngaphakathi kwesibhamu bese idedelwa phezu kwento ezogqitshwa.Ukufafaza kuhlanganisa ikakhulukazi iyunithi yokuhlinzeka, isibhamu sokufutha kanye nejeneretha yenkungu.Kufanelekile ukufafaza i-insulation yangaphandle yodonga lwezakhiwo, ukufafaza i-insulation yangaphakathi yodonga, ukufafaza i-insulation yokugcina ebandayo, ukufafaza i-insulation yomsindo we-car hulls, ukufafaza i-anti-corrosion yemikhumbi yemikhumbi, ukufafaza ukuvimbela amanzi ophahleni nezinye izimboni.

Yiziphi izinyathelo zokuphepha zomshini wokufafaza we-polyurethane?

Yini okufanele ngiyinake ngesikhathi senqubo yokumboza ye-polyurethane sprayers?Isikhala sihlukile kuhlobo ngalunye lwe-polyurethane.Khumbuza wonke umuntu ukuthi ngesikhathi sokwakhiwa, i-polyurethane kufanele ihlukaniswe ne-hydraulic spraying, spraying pneumatic, njll. Ngikunikeza imininingwane.

1. Khumbula ukulungisa isitayela somshini kusengaphambili.

Ngokuyinhloko, lapho sifafaza, sincoma ukuthi uqale phezulu, phansi, kwesokunxele nakwesokudla kuqala endabeni, ungasebenzisi kakhulu ngesikhathi sokwakha.Ngokuyisisekelo, lapho i-polyurethane ipendwa kabusha lapho usebenzisa i-anti-corrosion polyurethane, isikhala sokwakha akufanele sibe sikhulu kakhulu.Ingabe i-polyurethane izacile kakhulu.

2. Khumbula ukufutha okungenamoya ngomfutho ophezulu.

Lokhu empeleni kuyindlela esheshayo ye-polyurethane.Ngokwezidingo zokwakha zokufafaza izinga lokuqina nokuqina, izinguquko ekusebenzeni komshini wokufafaza we-polyurethane, ukuze kuzuzwe kangcono imiphumela edingwa ngamakhasimende.

Iyiphi indlela yokugcinwa kwe-polyurethane sprayers?

1. Ukugcinwa kwe-polyurethane sprayer.Uma uhlelo lokufafaza nge-polyurethane luvalekile noma ludinga uthuli oluningi, kuyadingeka ukuthi ushintshe indawo yesihlungi somoya, ufafaze cishe izinsuku ezi-3 noma ngaphezulu ukuze uvule.Hlanza uhlelo lokuhlunga uwoyela ngemuva kwekhabhinethi.Futhi, njalo uhlanza amafutha ochungechungeni lwenethiwekhi yezokuthutha bese wengeza amafutha.

2. Ukugcinwa kwesistimu kaphethiloli.Uma isifutho sesiphelile, vula ivalvu yokubuyiswa kwesifutho ukuze upende ugeleze uye ethangini likayinki, khipha ithangi futhi uhlanze isincibilikisi.Faka ithangi lokuxuba, qala iphampu, vula i-valve yokubuyisela kanye nesibhamu ukuze ujikeleze i-solvent yokuhlanza emgqeni wamafutha futhi uhlanze isibhamu kanye nepompo.Iphampu nesibhamu kunembe kakhulu sicela ungaziqedi ngokuthanda kwakho.Ukuvimbela umonakalo.

3. Iphampu ye-pneumatic nesilinda kufanele ivalwe kahle ngemva kwesonto noma amahora angu-50 okusebenza, izinga lokuxega kwebhande ku-drive, izinga lokuqina kokuxhumanisa, ukubukeka kwepompo kufanele kuhlanzeke, gcoba amafutha amancane ukuvimbela ukunamathela kokungcola. .

4. I-Clutch, i-backflow yokulayisha i-valve, i-reducer, i-compressor yomoya nezinye izinto ezinkulu kufanele zihlolwe njalo ngokuvumelana nezidingo zokusetshenziswa.Uma kukhona ukulimala okugugile, kufanele kulungiswe futhi kushintshwe ngesikhathi.

5.PIthangi le-oliurethane yokufafaza umshini wokugcwalisa uwoyela wethangi elingcolile elihlanzekile.
