Indlela yokulawula indawo yentloko yokugalelaumatshini wokukhupha amagwebu ngoxinzelelo oluphezulukubandakanya intloko yokugalela kunye nomkhono obekwe ngaphandle kwentloko yokugalela.I-cylinder ye-hydraulic ethe nkqo icwangciswe phakathi komkhono kunye nentloko yokugalela.Umzimba we-cylinder we-cylinder hydraulic cylinder udibene nomkhono.Ivalve Intonga idityaniswe nentloko yokugalela.Kwangaxeshanye, kukho umgaqo kaloliwe othe tyaba kumatshini wesamente ogwebu amagwebu, kunye nomngxuma wesikhokelo ohambelana nomgaqo kaloliwe unikezelwa kumkhono.I-cylinder ye-hydraulic cylinder ethe tyaba ibonelelwe phakathi koxinzelelo oluphezulu lomzimba womatshini onamagwebu kunye nomkhono.Umzimba we-cylinder we-horizontal hydraulic cylinder uqhagamshelwe kunye nomzimba womatshini woxinzelelo oluphezulu, kwaye isiqu sevalve sidityaniswe nomkhono.Imodeli esebenzayo ineenzuzo zokugcinwa kwabasebenzi kunye nokusebenza kakuhle kwemveliso.

Amacandelo amabini A kunye no-B weumatshini wepolyurethane ugwebuzilinganiswe ngokuchanekileyo kwaye zixutywe ngesantya esiphezulu, kwaye iinqununu ezimbini ze-A kunye ne-B zihanjiswa kwintloko yokuxuba iipompo ezimbini ezichanekileyo zokulinganisa imitha.Emva kwesantya esiphezulu kunye nokuvuselela okunamandla, ulwelo lwezinto eziphathekayo lufafazwa ngokulinganayo ukwenza imveliso efunekayo.

Isityalo esipheleleyo soxinzelelo olunogwebu oluphezulu lunezi nkqubo zilandelayo: inkqubo yokuhamba kwezinto, inkqubo yokulinganisa, inkqubo yesekethe yomoya, inkqubo yokufudumeza, inkqubo yokucoca, izixhobo ezikhethekileyo ze-polyurethane foam infusion kunye ne-foam.Ngethuba nje icandelo le-polyurethane izinto eziluhlaza (i-isocyanate kunye ne-polyether polyol components) zidibana nezalathi zokusebenza zokuqulunqwa.Yenziwe nge-polyether polyol kunye ne-polyisocyanate phambi kwee-agent ezikhupha amagwebu, i-catalysts, i-emulsifiers kunye nezinye izongezo zekhemikhali, emva kokuphendula kweekhemikhali kunye ne-foam.Kukho iintlobo ezintathu zenkqubo yogwebu kumatshini woxinzelelo oluphezulu lokuphosa amagwebu: indlela ye-polymer yangaphambili, indlela ye-semi-polymer kunye nenyathelo elinye lokufoma i-polymer indlela yokwenza amagwebu e-pre-polymer (izinto ezimhlophe) kunye (izinto ezimnyama) kuqala, kwaye emva koko wongeze amanzi, i-catalyst, i-surfactant, ezinye izongezo kwi-pre-polymer exutywe phantsi kwesantya esiphezulu sokuxhokonxa ugwebu, emva kokunyanga kubushushu obuthile bunokuvuthwa.Inkqubo yogwebu ye-semi-prepolymer indlela kukwenza inxalenye ye-polyether polyol (izinto ezimhlophe) kunye ne-disocyanate (izinto ezimnyama) kwi-prepolymer kuqala, emva koko wongeze enye inxalenye ye-polyether okanye i-polyester polyol kunye ne-diisocyanate, amanzi, i-catalyst, i-surfactant. , ezinye izongezo, njl., kwaye uzixube phantsi kwesantya esiphezulu uvuselela ugwebu.I-polyether okanye i-polyester polyol (emhlophe) kunye ne-polyisocyanate (emnyama), amanzi, i-catalyst, i-surfactant, i-agent evuthelayo, ezinye izongezo, njl njl.Inkqubo yenyathelo elinye logwebu yeyona nkqubo ixhaphakileyo esetyenziswayo namhlanje.Kukwakho nendlela yokwenza ugwebu lwemanyuwali, eyona ndlela ilula, apho zonke izinto ezikrwada zilinganiswa ngokuchanekileyo, zifakwe kwisikhongozeli emva koko zixutywe ngoko nangoko kwaye zitofelwe kukungunda okanye isithuba ukuze kuzaliswe ugwebu.Qaphela: I-polyisocyanate (emnyama) kufuneka ilinganiswe ekugqibeleni.

Iumatshini we-polyurethane foame ngokubanzi amagwebu kubushushu begumbi, kwaye inkqubo yokubumba ilula.Ngokomgangatho wokwakha oomatshini, inokwahlulwa ibe ngamagwebu ezandla kunye nogwebu lomatshini;ngokoxinzelelo lwe-foaming, inokwahlulwa ibe yi-low-pressure foaming kunye ne-low-pressure foam;ngokwendlela yokubumba, inokohlulwa ibe ukugalela amagwebu kunye nokutshiza kugwebe.
