Phakathi kwazo zonke izinhlobo zemikhiqizo ye-polyurethane,polyurethane high-pressure ugwebu umshiniigwebu yingxenye ebalulekile.Isici esiyinhloko se-polyurethane enamathela ukuthi ine-porosity, ngakho-ke ukuminyana okuhlobene kuncane, amandla athile aphezulu, futhi iphinde ibe nokufakwa komsindo, ukumelana nokushaqeka, ukufakwa kukagesi, ukumelana nokushisa., ukumelana nokubanda, ukumelana ne-solvent nezinye izici.Umhleli olandelayo uzothatha ukuthi uqonde ukuthi ukumelana okubandayo kwempahla yokubumba yesifutho yemishini yomshini we-polyurethane foam injani.
Ngokuvamile, inezici ezinhle zokusebenza, okuqukethwe okuqinile okuphezulu, nokusebenza okuhle kuzo zonke izici.Kuwuhlobo lwezinhlobonhlobo zepende ezinamathemba amakhulu okuthuthukiswa.Izikhombisi-ndlela eziyinhloko zokufaka isicelo ziyizingubo zokhuni, okokukhanda izimoto, okokuvikela ukugqwala, ukumboza phansi, ukumbozwa nge-elekthronikhi, okokugqoka okukhethekile, njll. Okubi ukuthi inqubo yokwakha iyinkimbinkimbi, indawo yokwakha idinga kakhulu, futhi ifilimu kapende othambekele ekubeni namaphutha.
Izingubo ezinengxenye eyodwa ye-polyurethane ikakhulukazi zihlanganisa uwoyela we-urethane, izimbotshana ze-polyurethane eziphulukisa umswakama, kanye nohlobo oluvaliwe lwemishini ye-polyurethane enegwebu.Indawo yohlelo lokusebenza ayibanzi njengezinto ezimbili zokumboza, ikakhulukazi ezisetshenziselwa ukumboza phansi, okokunqanda ukugqwala, okokufaka amakhoyili angaphambi kwekhoyili, njll., futhi ukusebenza kwayo konke akuhlanganisi njengezinto ezimbili ezinento eyodwa.I-varnish ehlukahlukene yepende ye-polyurethane ibizwa ngokuthi i-polyurethane varnish.
I-polyurethane foam ihlukaniswe yaba igwebu elithambile negwebu eliqinile.Zinezakhiwo ezahlukene kanye nokusetshenziswa okuhlukene.Umsebenzi wegwebu elithambile uwukuba umcamelo, ongasetshenziselwa ukwenza amasofa, ama-cushions nezinye izinto zangaphakathi zezimoto, kanti umsebenzi wegwebu eliqinile uwukugcina ukufudumala nokungangeni kwamanzi, futhi kuvame ukusetshenziselwa ukusiza.Ukufakwa kwamabhodi wokwakha, izindonga zokushisa ezishisayo.Ukusetshenziswa kwegwebu le-polyurethane kubanzi kakhulu, futhi kuyimpahla ebaluleke kakhulu ezimbonini eziningi, futhi okokusebenza okusetshenziselwa ukuqedela inqubo yomshini wokugcwalisa amagwebu we-polyurethane umshini wokugcwalisa i-polyurethane foaming umfutho ophezulu, ngakho-ke ukubaluleka kokusetshenziswa kwe-polyurethane foaming Iyahamba. ngaphandle kokusho.
Ukuhlelwa okuphelele kwezinto zokusebenza kucabangela ngokugcwele ukusetshenziswa kwendawo.Ngisho nangemva kokwamukela amasethi amaningi wamaqembu amapayipi okushisa ashisayo, indawo enyakazayo eklanyelwe isengaqinisekiswa, futhi umqhubi oyedwa angaphusha futhi adonse okokusebenza.Ukugcwaliseka komsebenzi wokuthwala umthamo omkhulu weqembu lepayipi lokufakwa kwemishini kwandisa ukusetshenziswa kwemishini yegwebu le-polyurethane, esiza kakhulu opharetha, okungagcini nje ngokusindisa abasebenzi kodwa futhi kuthuthukisa ukusebenza kahle.
