Ungazihlanza Kanjani Izinsiza Ze-Polyurethane Foam

Ukusebenza okulungile kokuhlanza akukwazi nje ukuqinisekisa ukusebenza okuvamile kwemishini, kodwa futhi ngokuphumelelayo kwandise impilo yesevisi yemishini yokugwedla.Ngakho-ke, kungakhathaliseki ukuthi yikuphi umbono, kubaluleke kakhulu ukuhlanza imishini ye-polyurethane foaming ngendlela efanele.

Isici esibalulekile sokugcinwa kwemishini ye-polyurethane foam ukuhlanza.Lapho uhlanza izinto zokusebenza, naka amaphuzu alandelayo:

1.Imishini ye-polyurethaneipayipi lokushisisa:

Lapho ukufutha sekuphelile, cindezela inkinobho yokukhulula ingcindezi (PARK), bese udubula isibhamu ukuze ukhulule ukucindezela ku-500-700psi.Ukukhululeka kwengcindezi kungamiswa.Ngoba lapho kukhona ukucindezela okuthile epayipini, umswakama emoyeni ngeke ungene kalula epayipini, okuqinisekisa ukuthi izinto zokusetshenziswa ngeke zithinteke emoyeni omswakama, futhi impahla A ngeke yonakale noma icwebezele epayipini. ;isiza kakhulu.

2. Impahla Iphampu yokumpompa yeimishini ye-polyurethane:

Ngemuva kokusetshenziswa, hlanza ukubukeka kwayo nge-ejenti yokuhlanza, bese uyifaka emgodini ovikelayo one-ejenti yokuhlanza ukuze injini eyinhloko ivalwe, ukuze uvimbele inani elincane lezingxenye ze-isocyanate ekuphenduleni ngomswakama emoyeni, okubangela. i-feed Ijubane liyancipha, isilinganiso sokumpompa asisebenzi, futhi iphampu yokulingana ayinalutho.

3. Ukuhlanzaimishini ye-polyurethane:

Uma isikhawu phakathi kokuphothulwa kwalokhu kwakhiwa kanye nokwakhiwa okulandelayo sifinyelela izinsuku ezingaphezu kwezingu-30, lonke uhlelo lwe-A kumele luhlanzwe kahle futhi luvalwe.

4.Imishini yokugcwalisa i-polyurethane(umshini okhiqiza amagwebu) isilinda esilinganayo:

Ngesikhathi sokusebenza okujwayelekile komshini wegwebu we-polyurethane, naka uhlelo lokuzihlanza lwe-A cylinder yezinto, noma ngabe uketshezi lokuhlanza olujikelezayo lujikeleza ngokujwayelekile, noma ngabe uketshezi lokuhlanza lube ne-turbid, crystallized, njll., uma kukhona okungavamile. ukujikeleza, hlola ukuthi ipayipi loketshezi lokuhlanza livinjiwe, noma hlola ukuthi kukhona i-crystallization kusilinda A;uma uketshezi olujikelezayo luyi-turbid futhi lucwebezela, ludinga ukushintshwa ngesikhathi.
