Ukugqoka kwe-polyurea kokuvuselela udonga: Inketho entsha enobungani nemvelo futhi esebenza kahle kakhulu yezakhiwo
Ngenxa yokukhula okuqhubekayo kwesidingo sokuvuselelwa kwedolobha kanye nokuvuselelwa kwezakhiwo ezindala, uhlobo olusha lwezinto zokumboza udonga oluhlanganisa ubungane bemvelo, ukuqina kanye nokukhanga kobuhle - i-polyurea coating - kancane kancane iba "intandokazi entsha" embonini yokwakha. Muva nje, amaphrojekthi okuvuselela izindawo zokuhlala ezindala ezifundeni eziningi aqale asebenzise ubuchwepheshe bokumboza udonga lwe-polyurea, enikeza ikhambi elisha sha lokuvuselela udonga.
Ukusungula Izinto Ezintsha Kwezobuchwepheshe: Izinzuzo "Eziyinhloko" Zezimbozo Ze-Polyurea
Izembozo ze-polyurea ziwuhlobo lwezinto ze-elastomer ezakhiwe ukusabela kwezingxenye ze-isocyanate kanye nama-amino compounds. Zinezici ezifana nokuqina okusheshayo, ukuqina okuphezulu, ukumelana nokugqwala, kanye nezakhiwo zokulwa nokuguga. Uma kuqhathaniswa nopende we-latex wendabuko, amathayili e-ceramic, nezinye izinto zokuvuselela, ukusebenza kahle kwazo kokwakhiwa kukhushulwa izikhathi ezingu-3-5. Ukusetshenziswa okukodwa kungafeza imisebenzi eminingi njengokuvimbela amanzi, ukulwa nokukhunta, kanye nokumelana nokuguguleka, futhi akudingeki ukulungiswa njalo. Isikhathi sazo senkonzo singafinyelela eminyakeni engaphezu kwe-10.
Ukuthuthukiswa kwezemvelo: Ukwakhiwa okuluhlaza kunegalelo entuthukweni esimeme
Izici zemvelo zezingubo zokugqoka ze-polyurethane nazo zidonsele ukunaka okukhulu. Ngesikhathi senqubo yokwakha, azikhiphi ama-VOC (amakhemikhali e-organic aguquguqukayo), zigwema iphunga elibi kanye nokungcola komoya okwenzeka ngesikhathi sokwakhiwa kwezingubo zokugqoka zendabuko; ngesikhathi esifanayo, izinto ngokwazo zingaphinde zisetshenziswe, kuhlangatshezwane nezidingo zesu "le-dual carbon" lokuguqulwa okuluhlaza embonini yokwakha. Ochwepheshe abavela kwi-China Academy of Building Research baveze ukuthi: "Ukukhuthazwa kwezingubo zokugqoka ze-polyurethane kuyisibonakaliso esibalulekile sokuguqulwa kwensimu yokuvuselelwa kwesakhiwo kusukela 'ekugcizeleleni imiphumela' kuya 'ekugcizeleleni izinqubo'."
Ukwandiswa kobubanzi besicelo: Ukumbozwa okunezinhlangothi eziningi kusukela ezindaweni zokuhlala kuya kwezimboni
Njengamanje, ubuchwepheshe obusha bokusetshenziswa kwezembozo ze-polyurea busetshenziswe kabanzi emiphakathini yokuhlala, ezakhiweni zezentengiselwano, ezitshalweni zezimboni, nakweminye imikhakha. Ezimweni zezimboni, ukumelana kwayo ne-asidi ne-alkali, kanye nokumelana nomthelela, kungaphatha ngempumelelo izindawo eziyinkimbinkimbi njengezitshalo zamakhemikhali nezindawo zokugcina impahla; ezimweni zezentengiselwano, isembozo esinwebeka kakhulu singazivumelanisa nokuguquguquka okuncane kwesakhiwo sesakhiwo futhi sigweme ukuqhekeka kwesibili.
Kusukela "ekulungiseni" kuya "ekuvuseleleni", izembozo ze-polyurethane zisebenzisa amandla obuchwepheshe ukwakha kabusha "izinga lokubukeka" kanye "nempilo" yezakhiwo zasemadolobheni. Ziqhutshwa kokubili ukwesekwa kwenqubomgomo kanye nesidingo semakethe, le nto entsha ingaholela emzuliswaneni olandelayo wokuguqulwa emkhakheni wokuvuselelwa kodonga.
