Umahluko phakathi kwePolyurethane esekwe emanzini kunye nePolyurethane esekwe kwiOyile
Ingubo engangeni manzi ye-polyurethane esekelwe emanzini sisixhobo esingangeni manzi esinobuhlobo nokusingqongileyo esineemolekyuli eziphezulu ze-polymer esinamathela kakuhle kwaye asingeni manzi. Sinamathela kakuhle kwi-substrates ezisekwe kwisamente ezifana nekhonkrithi, iimveliso zamatye nezesinyithi. Le mveliso ineempawu zeekhemikhali ezizinzileyo kwaye inokumelana nokukhanya kwelanga ixesha elide. Ineempawu zokuthamba okuhle kunye nobude obukhulu.
Iimpawu Zokusebenza Kwemveliso
1. Inkangeleko: Imveliso mayingabi namaqhuma emva kokuxutywa kwaye ifane.
2. Inamandla aphezulu okutsalwa, ilula kakhulu, iyathamba kakuhle, isebenza kakuhle kumaqondo obushushu aphezulu naphantsi, kwaye iyakwazi ukuzivumelanisa kakuhle nokuqhekeka, ukuqhekeka, kunye nokuguquka kwesiseko.
3. Ukunamathela kwayo kulungile, kwaye akukho nyango lwe-primer olufunekayo kwii-substrates ezahlukeneyo ezihlangabezana neemfuno.
4. Ingubo yomile ize yenze ifilimu emva koko iyakwazi ukumelana namanzi, ukumelana nokugqwala, ukumelana nokungunda, kwaye iyakwazi ukumelana nokudinwa.
5. Ukusebenza kwayo kwindawo esingqongileyo kulungile, njengoko ingenazo izinto ze-benzene okanye ze-coal tar, kwaye akukho solvent eyongezelelweyo ifunekayo ngexesha lokwakha.
6. Yimveliso enento enye, efakwa ebandayo elula ukuyisebenzisa nokuyibeka.
Ububanzi bokusetyenziswa kwemveliso
1. Ifanelekile kumagumbi angaphantsi komhlaba, iindawo zokupaka ezingaphantsi komhlaba, indlela evulekileyo kunye nemijelo
2. Iikhitshi, amagumbi okuhlambela, iislabhu zomgangatho, iibalconi, uphahla olungavezwanga.
3. Ukuthintela ukungenwa kwamanzi ngokuthe nkqo kunye nokuthintela ukungenwa kwamanzi kwiikona, ii-joints kunye nezinye iinkcukacha ezincinci, kunye nokuvala ii-joints zokuthintela ukungenwa kwamanzi.
4. Ukuthintela amanzi kwiidama zokudada, imithombo yokwenziwa, iitanki zamanzi, kunye nemijelo yokunkcenkceshela.
5. Ukuthintela amanzi kwiindawo zokupaka iimoto kunye nophahla olusikwere.
I-polyurethane engangeni manzi esekwe kwioyile yi-polyurethane engangeni manzi ephezulu eyomisa kwaye iqine phezu komphezulu. Yenziwe ngee-isocyanates kunye nee-polyols njengezinto eziphambili, kunye nee-arhente ezahlukeneyo ezincedisayo ezifana nokuxuba i-latent hardeners kunye nee-plasticizers, kwaye iveliswa yinkqubo ekhethekileyo yokusabela kokuphelelwa ngamanzi obushushu obuphezulu kunye ne-polymerization. Xa isetyenziswa, ifakwa kwi-substrate engangeni manzi, kwaye ifilimu eqinileyo, eguquguqukayo nengenamthungo ye-polyurethane engangeni manzi yenziwa kumphezulu we-substrate yi-chemical reaction phakathi kweqela le--NCO end le-polyurethane prepolymer kunye nokufuma emoyeni.
Iimpawu Zokusebenza Kwemveliso
1. Inkangeleko: Le mveliso inomzimba ofanayo oqinileyo ongenajeli kunye namaqhuma.
2. Inxalenye enye, ilungele ukusetyenziswa kwindawo, ulwakhiwo olubandayo, kulula ukuyisebenzisa, kwaye imfuneko yomthamo wokufuma wesiseko ayingqongqo.
3. Ukunamathela okuqinileyo: Ukunamathela okuhle kwikhonkrithi, i-mortar, i-ceramics, i-plaster, umthi, njl.njl. izixhobo zokwakha, ukuzivumelanisa kakuhle nokuncipha, ukuqhekeka kunye nokuguquka kwe-substrate.
4. Ifilimu engenamthungo: Inamathela kakuhle, akukho mfuneko yokufaka iprimer kwii-substrates ezahlukeneyo ezihlangabezana neemfuno.
5. Amandla aphezulu okuxinana kwefilimu, isantya sokwandiswa okukhulu, ukuthamba okuhle, ukuzivumelanisa kakuhle nokuncipha kunye nokuguquguquka kwesiseko.
6. Ukumelana neekhemikhali, ukumelana nobushushu obuphantsi, ukumelana nokwaluphala, ukumelana nokungunda, ukusebenza kakuhle kokungena kwamanzi. Ububanzi bokusetyenziswa kwemveliso
Ingubo engangeni manzi ye-polyurethane esekelwe kwioyile ingasetyenziselwa ukwakhiwa kwezakhiwo ezintsha nezindala, uphahla, amagumbi angaphantsi komhlaba, amagumbi okuhlambela, amachibi okudada, iiprojekthi zokhuselo loluntu, njl. Ingasetyenziselwa ukwakhiwa kwepayipi zesinyithi ezingangeni manzi.
Umahluko phakathi kwe-polyurethane esekelwe kwioyile kunye ne-polyurethane esekelwe emanzini:
I-polyurethane esekelwe kwioyile inomxholo oqinileyo ophezulu kune-polyurethane esekelwe emanzini, kodwa yenziwe nge-isocyanate, i-polyether, kunye nee-arhente ezahlukeneyo ezincedisayo ezifana ne-mixed latent curing agent kunye ne-plasticizers, ezilungiselelwe ngeenkqubo ezikhethekileyo kubushushu obuphezulu, njengokususa amanzi kunye ne-polymerization reaction. Inomgangatho ophezulu wongcoliseko, xa ithelekiswa ne-polyurethane esekelwe emanzini, eyimveliso eluhlaza neyokusingqongileyo engenangcoliseko. Ifanelekile ukusetyenziswa ngaphakathi, njengeekhitshi kunye nezindlu zangasese.
