Ukutshiza ngePolyurethane sisixhobo sokutshiza soxinzelelo oluphezulu lwepolyurethane.Ngenxa yokuba izinto zeizixhobo zokutshiza ezinoxinzelelo oluphezuluibethelwa kwigumbi elincinane lokuxuba kwaye ijikelezwe ngamandla ngesantya esiphezulu, ukuxuba kuhle kakhulu.Izinto ezihamba ngesantya esiphezulu zenza amathontsi enkungu acolekileyo kumlomo weumpu wokutshizakwaye uzitshize ngokulinganayo kumphezulu wento.Ukutshiza nge-polyurethane enegwebu kusetyenziswa ikakhulu ukugcina ubushushu kunye nokutywinwa kokugcina ubushushu kunye nefriji.Isetyenziselwa ukugquma izinto zokugquma ezishushu ezifana neetanki ezinkulu zokugcina ezingqukuva, izifakelo zombhobho ezinobukhulu obukhethekileyo obunobukhulu obukhethekileyo, kunye neendonga zokugcina ezibandayo, kwaye inokuqonda ukuphuphuma kwamagwebu kwindawo.
Iingxaki ezininzi zihlala zidibana ekwakhiweni kwe-polyurethane yokutshiza, ngoko ke ziziphi ezi ngxaki?Yenzeka njani le nto?
Lo ngumba wokusebenza, ochazwa ngolu hlobo lulandelayo:
| Ingxaki eqhelekileyo | Isizathu | Cebisa |
| Umphezulu wegwebu orhabaxa kwaye ungaqhelekanga | I-atomization engalunganga, ngakumbi ixhaphake kakhulu kwizitshizi zokuxuba umoya zasekhaya | Uxinzelelo lwangasemva lwe-compressor yomoya kunye nomgama ukusuka kwisiseko seplate unokulungiswa ngokufanelekileyo.Ukuba kunokwenzeka, yandisa kwaye unciphise umlomo wokuxuba umoya.Umncinci omncinci.Isitshizi soxinzelelo oluphezulu lwe-polyurethane sinokugcinwa ngokufanelekileyo kude ne-substrate. |
| Ixesha le-Foaming likhawuleza kakhulu kunye ne-viscosity emnyama namhlophe | ||
| Igwebu lithambile kakhulu | I-polyether eninzi kakhulu | Kucetyiswa ukuba wenze uvavanyo lwasimahla lwegwebu kumlinganiselo ochanekileyo.Ukuba isathambile, unokwandisa umlinganiselo we-isocyanate l ngokufanelekileyo.Ukuba isathambile, kufuneka ihlolwe ukuba i-ethylenediamine kufuneka isetyenziswe, ngokufanelekileyo ukwandisa izinto ezisetyenziswayo kwizinto ezimhlophe. |
| igwebu libukhali
| Amanzi amaninzi kakhulu kwinkqubo | Ukuba umphezulu womhlaba u-brittle, cinga ukuba umahluko phakathi kobushushu bezinto eziphathekayo kunye nobushushu be-ambient mkhulu kakhulu, ukuba ubushushu bezinto eziphathekayo buphezulu, kwaye ubushushu be-ambient buphantsi.Esinye isizathu kukuba kukho umahluko omkhulu kwi-viscosity phakathi kwe-polyether kunye ne-Isocyanate kunye ne-isocyanate engaphezulu. |
| Umahluko we-viscosity phakathi kwe-polyether kunye ne-Isocyanate mkhulu kakhulu | ||
| Amandla e-peel ephantsi phakathi kwe-foam kunye ne-substrate | Umphezulu we-substrate awucocekanga, kunye nothuli oludadayo okanye amabala e-oyile | Kwakungekho ukungena kwe-substrate, kwaye umswakama kwi-interface wawubonakala ngokucoca.Ukongeza, ubushushu be-substrate buphantsi kakhulu, kwaye isantya sogwebu sikhawuleza kakhulu.“Ukutshiza” (okt ukutshiza umaleko omncinci obhityileyo ngokukhawuleza), kodwa isitshizi esingqindilili sisenokubangela uxinezeleko olugqithisileyo kunye nokuxobuka. |
| iqamza
| Ngenxa yeqondo eliphantsi le-branching kunye nokusebenza kwe-polyether esetyenziswe kwinkqubo yokugaya | I-Sucrose, i-mannitol inokudibaniswa njengesiqalo se-polyether ngokufanelekileyo.Ukongeza, ngokufanelekileyo ukwandisa inani leeleya zokutshiza ngexesha lokwakha ukuphepha ukuphinda kwenzeke |
| hlukana
| Ixesha logwebu likhawuleza kakhulu okanye licotha kakhulu | Nika ingqalelo ukulawula isantya sogwebu |
| I-silicone eninzi kakhulu ye-oyile ye-oyile yongezwa kwinkqubo yogwebu |
