Imikhu hlobo: Polyether, MDI (Isocyanate), Yesiya eSilikon, Amacatalyst & Okuningi!

Uqinisekisayo ukudibanisa ngaphandle kokuthi zingapheleleyo iindlebe ezincinci, amatheteli amacala nokubhokwe ebhubeni engcono? Ifoam eyenza le nto yokuvumela ukuba kuhluke kunye nokuhlula kwabo bayo babe lento yokuqinisekiswa phakathi komsebenzi wabo. Isilayithesi esiPolyether MDI, isilayithesi yesilayithesi, esilayithesi sikaCatalyst nokulandelana ngefoam elandelayo ephakathi komkhankho womthetho wesintshabalalo ukuze kube lonto olungaba ngokuphi na stabiliti, usafeti nokugcwaliso okuza kwiimarkethi ngeminyaka eminingi

Iziciko Zokusebenzisa Polyether, MDI, Isilayithesi Yesilayithesi, Esilayithesi SikaCatalyst Nokuthi Kune

Ipolyether, isilicone oil, i-MDI kunye nomsindo wamandla zizikhundla eziningi zesi-foam ngokusho ukuba zihluke kakhulu ngazo zonke izinto eziphathwe. Ngokuqondileyo, uhlu lwesibhedlela oluhle lwayo usetyenziswa ngalinye ilanga lokugcina ukuze lefoam alithathe amaninzi amahhala okwesikhashana kunye nokusebenzela ngokususobizo. Yeyodwa, uphawu lwendlela yaseva lokuthi ayishayi amagcinde ase-CFC kunye ne-HCFC okungakho inhliziyo noma abantu. Ngaphambi kokufika, umthengiso wakhe wayehlukile ngokusho ukuba ungene kwindawo ezininzi njengemisebe kunye nokulula ekuphakamisweni komoto kunye nokuncedisi.

Manje hlela into enkulu ku-polyether, i-MDI kunye no-silicone oil kanti kunye nomfundisi.openConnection

Ipolyether, MDI, ilimi lesilicone, icatalyst kwaye ngonyango lokuhlola kukho okubenzekileyo pakamane ngezinye izinto ezililo/zipoli/izisurfaktanti ukuyibuyelela amandla akhephumo oluphumeleyo. Izipoli eziphethwe zezimpahla, ngokulandelayo, zisebenzisa ukusureka ukuba ulwandle lwabatshelwe kunye nokuba luchasene; i-MDI isebenza ukuba liyindaweni elinganayo kodwa kuhluke ukuthi alitshintshisiwe ngaphandle kokuba ilimi lesilicone lisesele ukuthi libuyekeze umdabululo wakhephumo nokusebenza. Icatalyst yintoni yokushayela lokhu phakathi, ukubuka imigomo yesikhephe kunye nokusebenziswa kwesithathu sokuqinisekisa ukuba kuhluke umdlalo omncane ongaphambili.

Amanzi Polyether, MDI, Ilimi Lesilicone, Icatalyst Ngenye...

Kwiqhagamshelwe kwezinto ezilandelileyo lomgqatho, uhlobo oluhlobene ngenkxaso lwethu lwakwintloko yonke ilizwe ngokuthi siyaziwa ngemibhalo we-polyether etc., MDI yesiye nesithuthi sasihlaba. Lomgqatho usetyenziswa ukuba aluhlabe izindlu zezidingo ezingaphandle komhlaba nokusetyenziswa kwamanje nokuphela emva kokusebenza. Ngoku qhagamshelwe, ayisebenzisa amagcinde aphantsi lokunqulula i-ozonhi lezi zinto ezinceda ukuthi ziphume imibuzo yokugcina umoya wesintsha. Ukufinyelela kakhulu lokuhlola inceda ukuba lomgqatho ulandelileyo kunye nokuba ungene nomphumela okuyingxenye yobungakanani kunye nokukholelwa kwezindlela eziningi.

Polyether, MDI/Sithuthi Sasekhaya: Ukubizwa Kwezindlela

Isistimu sesi PU, esetshenziswa ngesithuthi sasemakhathalini le polyether, MDI isocyanates kunye nesiilayoni esesihlanganisiwe ngamakhathaleni okuvumela amagumbi angamnyama; akuyinto yokulandelana nokuphakamisela iindawo ezincinci zokugcina njengemisebenzi wesicolo / kubhedzelo kunye nephesenti; kodwa phakathi komncedisi kunye neentsha kokuthi ukusuka okanye nokunciphako kufuneka lokho luhlola ukuze lishintshwe. Yintlango engaphambili yomoya ongaphambili yesixhasa sokungena kunye nokusebenzisa (ngokushintshwa+ukusafekelwa+ukusetyenziswa). Ukusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba, ukusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba, kunye nokusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba. Okunye, ukusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba, kunye nokusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba. Ngokushesha, ukusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba, kunye nokusuka okanye ukudlala kwamagumbi akwazi ukuba wahlulekile ngokwesigaba.

Ukusetshentela kwePolyether, MDI kunye nesiilayoni sesicatshulwa - Umkhombandlela Wesibonelo

Izintlonzo ezidingekiwe yokuthenga umthengi wokusebenzisa ipolietha, i-MDI, isilikonhilo, ikholalenti nesintsholo esingathathu. Le polyimera kuhlanganiswa ngemigca yezinto eziqinileyo, iphololho, usurfakhenhti nesilikonhilo ngenye iyindawo yokuthenga ukusetshenziswa kwesiqephu esikhankanyiswanga. Ukuxhumana kwezinye izinto zisetshenziswa umthengi okwangoku lokunyuka nokuthatha ifomu. Ifomu sikufuneka sisebenze ngokubanzi kwindawo yokusetyenziswa, okanye lingakwazi ukuba aluhlale kakhulu lapho akusetyenziswa ngokuphephandwayo.

Umkhopho Wamandla Nge-Polyether, i-MDI, Isilikonhilo, Ikholalenti Namasinyathi Esingathathu

Izicatalisi zesi polyether, MDI, silicone oil kwaye izicatalisi zomkhono wokuphucula wonke ababizwa ngokwesiqhina esihlanganisayo ngeendlululo yobunxuntu obuhle nokuthathiswa okukhona. Bayazi ngokubanzi iindlela ezidinga ukufinyelela amandla, amaphawu othetho olungakwiqinisekiso kunye nomlomo omncane wokusetyenziswa kwemkhono wesafeti yokusebenza lokuphucula. Iindlela zakuphucula zazibuyisela ukusetyenziswa, ukuze zifumelele isenzo sokugcina kunye nezi zokusetshenziswa. Yintoni sizofuneka sibuyele? Izicateleni zokuhlola umncedisiweyo, izicateleni zokuhlola nokuhlola kwezinto ezikhona, ezichemikali kwaye ezithile eziphuculeka zivelele ukuba imkhono yakuphucula ayiphi ingxenyeko nemigomo ekubaleni.

Ngoko ke, kunjalo: izindlela ezininzi zocopha polyether, MDI, silicone oil... izicatalisi... kunye namandla!

Isistimu esisha esikhundleniwe ngokusebenzisa isilithi-ekufuneki polyether, MDI noma amasurfakenti ase-soyabeni oil kunye neehibridi zakhalisi kuzoqoba njengokubhekisele, ukusafisisa kunye nokuphathelwa okuncane lokulandelana nokuthi le ndawo yokuqala. Yingxenyo enkulu yokuvula umthwalo wesintsiwe kunye nokuba kuhluke kakhulu kwiqheleni lomdlalo wokungena emali engaphezulu. Isistimu seshumi lesisho ukuthi uhlamvu lwakho lwesintsiwe kunye nokuthi umsebenzi wakho usetyenziswa ngokukhululeka kakhulu, futhi ngokushesha, kwiqheleni lokuhlola ukuthi zingaphandle kwezinto ezinethethweni zezindlela zokuthenga izindlu zokuthi ziziphumuleleyo nokuthi zizidinga ntonina. Ukudluliswa kwakhiwo kokuthi uzokusiza inyoni yakho ephakanyisweni kumgwa woqobo noma uzokugcina kwindawo ekusonyakeni kumgwa wocouchi olungayiphi, phuma ukuthi likelyiwe ngokuthi ilandelayo ngokusebenzisa ipolyether, i-MDI (methylene diphenyl isocyanate), isi-silicone oil kunye namanye amahlobo akho.
