Polyurea - ntoni na? polyurea zingangenwa

Iindlela of Ipeyinti uphawu kunye isakhiwo kudala yahlulwe yaba ziindidi ezimbini: izinto zendalo kunye zokwenziwa. Isimanga, le mihla kusekho indawo kwakhe izinto zendalo ekrwada, obuphakamileyo zokwenziwa kabani yokusebenza. Kodwa phakathi abameli ababambeleyo esiyenziwe ukuba ngezixhobo zemveli zininzi iindlela befanelekile. Kule manqaku neenqwelwana, polyurea. Yintoni na yaye kutheni luyimfuneko - le mibuzo ixesha elide bengengabo ezifanelekileyo abakhi zobungcali, kodwa nje elula kufuneka aqonde ngokweenkcukacha. Ngenxa iimpawu ezizodwa zezi zixhobo eyenziweyo yenza kube lula ukwenza yokugquma ezikumgangatho ophezulu, ngokubuyisela inkoliso izixhobo eziqhelekileyo qela.

ulwazi ngokubanzi malunga polyurea

Material is a Polymer eyenziweyo kunye nesakhiwo sayo kufana polyurethanes, ezo kuhlelwe yi copolymerization of diisocyanates. Eneneni, bangene ke iqela elastomers kunye neempawu ezimisele balihlutha polyurea. Yintoni na ukusuka kwindawo umbono isicelo pfunaka? I ezibonakalayo kuqala ekwaziyo wokusungula ukutyabeka owomeleleyo ixesha elide. Izinga ukulahlwa abasabela kakhulu eliphezulu, kunjalo, lokuvelisa iimveliso sukube kusenokufuneka ukuba benze utshintsho zeteknoloji olongezelelweyo.

Enye inkalo kwezinto eyenziweyo ngenxa nucleophilicity eliphezulu amine. Oku kuthetha ukuba isakhiwo kweemveliso ezigqityiweyo akanaluvelwano ukufuma. Yiyo le luphawu, yaye ezichongiweyo omnye wemisebenzi ezingundoqo asetyenziswe ekwakheni polyurea ukutyabeka - zingangenwa.

imihlobo polyurea

Omnye ndingatsho ukuba iqela lonke iipholima ukuba oqhagamshelwano phakathi kwaye kwezinye ingqiqo ukuze ulungiso omnye komnye. Nangona kunjalo, xa polyurea, kukho zenyathi ezimbini ngokwesiseko ezahlukeneyo: le khompawundi aliphatic kunye enuka kamnandi. Uhlobo lokuqala umdla ukuba zingasetyenziswa ukwenza ukutyabeka enganyangekiyo UV. Okt processing polyurea ekwimo ukutyabeka ayikho likhubazeke kwaye angalahlekelwa umbala kwayo phantsi kwempembelelo kwelanga.

Uhlobo lwesibini - polyurea enuka leyo zizakujongwa njengo izinto ezahlukahlukeneyo. Ngoko ke, ukuba ukutyabeka ifanelekileyo aliphatic ukukhusela uphahla, le ngobuwena ngokufanelekileyo ukuba zingangenwa isiseko, kwaye njengendlela zokunyanga imiphezulu zokuhomba ngaphakathi. Ukongeza, ukuba zingangenwa polyurea lisetyenziswa namhlanje ekuveliseni izixhobo kunye nezithuthi, kwakunye ekudalweni imiqobo enganyangekiyo yokhuselo ukuba izitishi hydro kunye namaziko.

Omnye icandelo-yaye isixa-amabini

Kuba ingqiqo osahluleyo kufuneka lwenziwe ngemigaqo basabela polyurea. Le nkcazelo standard yi-candelo ezimbini ukwakheka, apho usebenza phantsi kwempembelelo kuvala. Oko kukuthi, inkqubo Ukuqinisa ithatha indawo esebenzisa candelo nkarhinyana. Ngoku kuyimfuneko ukuba kulungiswe umbuzo wokuba yintoni na omnye-component polyurea. Ntoni na kule nkqubo amanzi Ipeyinti? Kuyinto elula ukuba ukusebenzisa loo mbandela, ayidingi ngunobangela indlela, oko kukuthi, i-crystallization wenziwa ngokuzimeleyo, elikuvumela ukuba wenze processing manual.

Kubonakala lula ukusebenzisa push-Icandelo kufuneka ezaqanjwa kwindawo yokuqala, ukutyhala unzima kakhulu bicomponent analogu. Nangona kunjalo, ngokwemiqathango yobugorha meko ukutshintsha kwelinye icala. Icandelo-One ezaqanjwa kufuneka isetyenziswe njengento ukhuseleko ongumncedani, kodwa elijongene iinxalenye yokwenza polyurea eqhelekileyo kufuneka isetyenziswe. Izandla zakhe kwaye isicelo okwicandelwana amabini, eyona nto ibalulekileyo - ukusebenzisa izixhobo ezikhethekileyo kule njongo.

urea technology zingangenwa

Kukho iindlela ezininzi apho olu hlobo ukuba zingangenwa uyasetyenziswa. Le processing nezitya imiphezulu, ngokulitywina iziseko kunye uphahla nokhuseleko lwamanzi. Kwiimeko ezininzi, ukutyabeka lisetyenziswe ngokuthi meko indlela maleko ubhityileyo. Umahluko ndlela inokuba ngenxa neemfuno imithwalo kwi-inshorensi, kwiimpembelelo zangaphandle, kwaye ngoko ke iqondo adhesion. D. Kwakhona, amanzi polyurea ingaqhutywa usebenzisa zililo olunye okanye icandelwana-emibini. Xa sisebenza kunye izinto ezifana iziseko kunye nezakhiwo uphahla, kungakuhle ukuba usebenzise-udidi lwesibini kuthetha, kuba iimpawu kuvuthwa amandla. Ngaphantsi ukumelana emzimbeni iimpembelelo zingangenwa ingasetyenziswa njengento ukutyabeka abangabancedani zokhuselo.

processing manual

Njengoko sele kukhankanyiwe, processing ozimeleyo efanelekileyo omnye-component kuqamba. Phambi kokuba izinto isicelo kufuneka exutywe kunye polyurea ngamanzi. Noko ke, amachiza kufuneka kwenziwe kuphela phantsi kweemeko viscosity eliphantsi. Kwezinye iimeko kwanele ukuba usikhwezele isisombululo kumbala ngendlela efanayo. Kwiimeko ezininzi, isicelo polyurea manual ayifuni ukubandakanyeka isixhobo ekhethekileyo okanye ezinye amacandelo abangabancedani. Kuyafuneka ukuba kusetyenziswa irola okanye ibrashi. Kodwa ukusebenza imiphezulu yesinyithi, kuyacetyiswa ukuba kusetyenziswe primer. Kwakhona kusetyenziswa unyango imiphezulu zeglasi. Emva kokugqitywa ngamanzi kufuneka alinde ngenye imini yokugubungela ufumene yokuqaqadeka eyaneleyo.

Processing nezixhobo ezizodwa

Abakhi Professional ukulungisa polyurea zokutshiza usebenzisa izixhobo ezizodwa. Ingakumbi ukuba ezi mfuno ziquka iiyunithi ngenxa ukutshiza Ipeyinti ubushushu nekhono. Ngokuqhelekileyo, le apparatus, olusebenza ngamandla yaye uyakwazi ukugcina ishumi ihlangana zokupheka for polyurea. Imifuziselo latest izixhobo isicelo polyurea banikwa kweeyunithi ezisebenzayo uhlahlelo baphathwa izikhombisi kwinqanaba umphezulu umxube, iimitha kwemali kunye nezinye izixhobo ezikhuthaza ergonomics izixhobo.

ezinye izicelo

Iindibaniso yokuqaqadeka nokuzabalazela ukufuma yabangela polyurea ngokubanzi. Kakade ke, okokuqala zonke isetyenziswa ukwakhiwa kunye nemisebenzi nokuyifeza ngeninako. Kodwa ke iingenelo umbandela ezihloliweyo kwaye imikhumbi neenkampani, iivenkile wokulungisa iimoto, amashishini iinkonzo bazibandakanya ngenkxaso yezobugcisa kwezakhiwo ezahlukahlukeneyo, iibrorho kunye namatanki. Kukwakho iinzuzo kulo mbandela njengento yokwambathisa ukusuka. Ukuze siqonde lo mhlaba Kubalulekile ukukhumbula impendulo yalo mbuzo, polyurea - yintoni na. Oku, ngaphezu kwabo bonke, Polymer nkqi-sentlalo, nto leyo inika itywina olusebenzayo kunye namandla. Oko kukuthi, ukuba inkqubo ngokuhambelana camera umphezulu kubekho nokuyifeza umaleko, a iibhulorho umkhuhlane ukulibala ngoko musa.

isiphelo

Njengazo zonke izinto zobugcisa zale mihla, polyurea ngaphambi lokukhuphisana esebenzisa bodwa ixabiso. Le izinto zexabiso, kodwa umphumo ixabisa. Enye into kukuba ukusetyenziswa zabucala kufuneka zisetyenziswe ngesandla nokusebenzisa polyurea njengoko yokuthenga izixhobo ezixabisa baya ukuyilahla ukusetyenziswa kwale ubugcisa. Ngokwahlukileyo koko, kwimeko iziganeko ezinkulu-isikali ngaphandle yokugquma napyliteley ekhethekileyo akwenze. kuthetha nomthamo zinika ukutyabeka efanayo, kwaye ndiya kubasindisa kwiindleko. Kufuneka kwakhona Makusoloko kukhunjulwa ukuba abenzi polyurea yahlukile, ngokulandelelana, kunye nokusebenza lophawu oluthile ungahluka.
