Polyurea - kuyini? polyurea ungangenisi amanzi

Esebenzisa ezinengilazi uphawu futhi timphawu tesakhiwo Sekuyisikhathi eside zihlukaniswe ngezigaba ezimbili: ngezinto zemvelo futhi zokwenziwa. Okuxakayo nje kulezi zinsuku kusekhona indawo material yemvelo eluhlaza, okuyinto luphakeme izindwangu zokwenziwa kabani ukusebenza. Kodwa futhi phakathi abamele zokwenziwa azithathi ngezinto zesintu kukhona izinketho eziningi ayakufanelekela. Kulesi zezitsha uchungechunge futhi polyurea. Kuyini futhi kungani idingeka - mibuzo isikhathi eside akuzona ezifanelekile abakhi abangochwepheshe, kodwa ongelutho navamile ukubaqonda ngokuningiliziwe. Ngenxa izimfanelo eziyingqayizivele le nto zokwenziwa kwenza kube nokwenzeka ukuba enze eliphezulu ukwahlukanisa, esikhundleni iningi amathuluzi ajwayelekile leqembu.

ulwazi olujwayelekile mayelana polyurea

Material kuyinto zokwenziwa polymer futhi oyiyo sifana polyurethanes, okuyinto kuhlelwe umqondo ngu copolymerization ka diisocyanates. Ngempela, engena iqembu elastomers nezimfanelo uzimisele possessed polyurea. Kuyini kusukela umbono esiwusizo? Eyokuqala impahla uyakwazi ukwakha enamathela okuqinile futhi isikhathi eside. Nokho Izinga ukungamukeleki ukuphendula impela high, womshini imikhiqizo udini kungase kudingeke benze ukulungisa okwengeziwe kwezobuchwepheshe.

Esinye isici zokwenziwa impahla ngenxa nucleophilicity eliphezulu ama. Lokhu kusho ukuthi isakhiwo se-imikhiqizo siphelile akanandaba umswakama. Kuyinto lesi sici, uhlonzwe omunye imisebenzi esiyinhloko esetshenziswa ekwakhiweni polyurea enamathela - ungangenisi amanzi.

izinhlobonhlobo polyurea

Omunye ongathi lonke iqembu zokwenziwa polymers kuthiwa oxhumene futhi ngomqondo othile angase wenze ushintsho nomunye. Nokho, polyurea, kukhona ezimbili zenyathi bahluke: zezakhi aliphatic futhi elimnandi. I okufana lokuqala ethakazelisayo ukuthi ingasetshenziswa ukwakha UV ukumelana enamathela. Okungukuthi ukucutshungulwa polyurea ngesimo luthi alufane akuyona sikhubazekile futhi akaphelelwa nombala ngaphansi kwethonya kwelanga.

Eyesibili uhlobo - polyurea elimnandi okungase kubhekwe njengendlela izinto ezahlukene. Ngakho, uma aliphatic enamathela ezifanele kakhulu ukuvikela ophahleni, lokhu samuntu siyafanelana ungangenisi amanzi isisekelo, futhi njengendlela yokuthola ekwelapheni evele Ornamental endlini. Ngaphezu kwalokho, ukuba zingangenwa ngamanzi polyurea isetshenziswa namuhla ukwenziwa imishini kanye izimoto, kanye ukudalwa ukumelana izithiyo lokuvikela Hydro iziteshi futhi izindawo.

Omunye-ingxenye futhi ezimbili ingxenye

Ukuze uthole ukuthi uyayiqonda incazelo yalesi ngokwahlukana kufanele kwenziwe izimiso ukuthi bayavuma polyurea. Indaba ejwayelekile laqanjwa ezimbili ingxenye, okuyinto ethatha ngaphansi kwethonya kulethe. Okungukuthi, inqubo solidification senzeka esebenzisa izakhi asizayo. Manje kubalulekile ukubhekana umbuzo yini polyurea olulodwa-ngxenye. Kuyini e inqubo nokuvikela ezinengilazi? Kuyinto elula ukuba sisebenzise lokhu kwaziswa, akudingi kulethe ukusabela, okungukuthi, crystallization Kwenziwa ngokuzimela, ezikuvumela ukwenza ukucutshungulwa mathupha.

Kunengqondo kulula ukuyisebenzisa push-ingxenye izingoma kumele kwasekuqaleni, ukusunduza bazikhandle kakhudlwana bicomponent analogo. Nokho, ngokuya ngamandla isimo uyashintsha kolunye uhlangothi. Omunye-ingxenye izingoma kufanele sisetshenziswe njengesigungu sokufaka Ukuvikelwa asizayo kodwa obhekene ekucubunguleni izingxenye polyurea ezivamile kumele usetshenziswe. Izandla zakhe futhi singasetshenziswa a-ingxenye ezimbili, into esemqoka - ukusebenzisa imishini ekhethekile le njongo.

ungangenisi amanzi ubuchwepheshe urea

Kunezindlela eziningana lapho lolu hlobo ungangenisi amanzi sisetshenziswa. Lokhu ukucutshungulwa imicengezi evele, uphawu izisekelo nophahla yokuvikela amanzi. Ezimweni eziningi, luthi alufane sisetshenziswa ngu sputtering ungqimba indlela mncane. Umehluko izindlela kungenzeka kubangelwa nezidingo imithwalo ikhava, amathonya zangaphandle, futhi ngakho-degree of adhesion. D. Nalapha futhi, kungenzeka ukuba zingangenwa ngamanzi polyurea kwenziwe usebenzisa izingoma olulodwa noma ezimbili-ngxenye. Ngo ukusebenza izinto ezifana izisekelo kanye izakhiwo zophahla, kuyatuseka ukusebenzisa lesibili uhlobo izindlela, kusukela izici amandla ziza kuqala. Ngaphansi ukumelana amathonya ngokomzimba ungangenisi amanzi angasetshenziswa njengenhlangano enamathela asizayo zokuzivikela.

ukucutshungulwa Manual

Njengoba sekushiwo, ukuze kusebenziswe ezimele ekahle Ukwakheka eyodwa-ngxenye. Ngaphambi impahla isicelo kufanele buhlanjululwe ngamanzi polyurea. Nokho, lo dilution kufanele kwenziwe kuphela ngaphansi kwezimo viscosity ongaphakeme. Kwezinye izimo kwanele ushukumisa isixazululo umbala ukufana. Ezimweni eziningi, manual isicelo polyurea akudingi ukubandakanywa ithuluzi ekhethekile noma ezinye izingxenye asizayo. Kumele Kusetshenziswe roller noma shayela. Kodwa ukusebenza metal evele, kungcono ukusebenzisa primer. Iphinde isetshenziselwe ekwelapheni ingilazi evele. Ngemva kokuphothulwa ungangenisi amanzi kufanele ulinde usuku olulodwa ukumboza atholwe ubulukhuni okwanele.

Icubungula imishini ekhethekile

abakhi abangochwepheshe ukulungiselela kanye polyurea spray usebenzisa imishini ekhethekile. Ikakhulukazi ngoba lezi zidingo zihlanganisa amayunithi ukuze sishaye Seamless ekuvikeleni ezinengilazi. Njengoba ungalindela, le-apharathasi, ezisebenza ngomfutho ophakeme futhi akwazi ukugcina eziyishumi ihlangana zokupheka polyurea. Izindlela zakamuva of imishini sokusebenzisa polyurea unikezwe amayunithi ukusebenza for ukuhlaziywa iphathwa ebusweni zamaleveli ingxube, ukugeleza amamitha namanye amadivayisi ezithuthukisa Ergonomics kulandzelana nekuhlunga tinsita.

Ezinye izinhlelo zokusebenza

Inhlanganisela ubulukhuni nokuzabalazela umswakama okubangelwa polyurea okwandile. Yiqiniso, okokuqala isetshenziswa ekwakheni nemisebenzi aqeda. Kodwa izinzuzo impahla esikalini kanye shipbuilding izinkampani, yokulungisa izitolo, inkonzo amabhizinisi okuyinto bekwi technical support izakhiwo ezahlukene, amabhuloho futhi amathangi. Kukhona futhi izinzuzo le nto njengenhlangano yisivikelo kusuka. Ukuze uqonde lokhu impahla Kuhle ukukhumbula impendulo yombuzo othi, polyurea - kuyini. Lokhu, ngaphezu kwakho konke, okusheshayo-ukubeka polymer, esihlinzeka uphawu ngempumelelo futhi amandla. Okusho ukuthi, uma inqubo ngokuvumelana camera ebusweni yokuqedela ungqimba, ke amabhuloho ibanda futhi akhohlwe.

isiphetho

Njengazo zonke izinto zanamuhla kwezobuchwepheshe, polyurea ngaphambi ukuncintisana izindlela engayodwa ngentengo. Lena impahla ezibizayo, kodwa umphumela kuwufanele. Enye into ukuthi ukusebenzisa kwangasese kumele kusetshenziswe ngesandla nokusebenzisa polyurea njengoba ukuthengwa kwemishini emisha uzokwenza zingenzeki ukusetshenziswa lobu buchwepheshe. Ngokuphambene, uma imicimbi emikhulu ngaphandle ukwahlukanisa napyliteley ekhethekile ukuzenza. Sokuphuzisa izindlela ukunikeza enamathela iyunifomu, futhi ngeke umsindise on izindleko. Kufanele kukhunjulwe ukuthi abakhiqizi polyurea zihlukile, ngokulandelana, futhi ukusebenza brand lesitsite zingahluka.
