I-Polyurea yipolymer ephilayo eyi-reaction ye-isocyanate kunye ne-amine ephelisiwe i-polyether resin, eyenza i-plastiki-efana ne-rubber-efana ne-rubber enjenge-membrane engenamthungo.
I-Polyurea idinga uqeqesho olukhethekileyo kunye nezixhobo zokusetyenziswa kwentsimi, nokuba isetyenziswe njengefayili edibeneyo okanye njengentsimi efakwe i-coating.UShundi unenkqubo eqhubekayo yeuqeqesho lwekontrakaendaweni.Kukho abafaki zicelo abafanelekileyo eTshayina.
Njengomthetho jikelele,Shundii-polyurea ingasetyenziselwa ukuqulatha nayiphi na into enokuthi ikhutshwe ngokuthe ngqo kwiinkqubo zesiqhelo zococeko.Inokusetyenziswa kuyo nayiphi na ikhonkrithi, isinyithi, umthi, i-fiberglass, i-ceramics surfaces.
I-Shundi polyureas iqala ukuphuhlisa iimpawu zabo zomzimba kwimizuzu yesicelo.I-polyurea enyangisiweyo inokuxhathisa ubushushu ukusuka kwi -40 ℃ ukuya kwi-120 ℃, Ngelixa i-polyurea inenguqu ephezulu yeglasi kunye nobushushu bobushushu bokuphambuka, iya kutshisa xa ibonakaliswe kwidangatye elithe ngqo.Iya kuzicima xa idangatye lisusiwe.Kodwa sikwanayo ne-polyurea ebamba umlilo kwiimfuno ezizodwa ezinje ngeetonela zikaloliwe kunye neendlela zokuhamba.
I-Polyurea inokuba nzima okanye ithambile ngokuxhomekeke kwindlela ethile kunye nokusetyenziswa okujoliswe kuyo.Iireyithingi zeDurometer zinokusuka kwiShore A 30 (ithambile kakhulu) ukuya kuShore D 80 (inzima kakhulu).
Ngokwenyani kukho iindidi ezimbini ezahlukeneyo zeenkqubo ze-aliphatic polyurea okwangoku kwintengiso.Olunye luxinzelelo oluphezulu / iinkqubo zobushushu ezitshizwayo kwaye enye yinto eyaziwa ngokuba yinkqubo yohlobo lwe "polyaspartic polyurea".Le nkqubo ye-polyaspartic yahlukile kuba isebenzisa i-ester-based resin component kwaye inobomi obude bembiza.Inokusetyenziswa ngesandla usebenzisa i-roller;iibrashi;iiraki okanye izitshizi ezingenamoya.Iinkqubo ze-aspartic azikho i-coating ephezulu yokwakha eqhelekileyo "ye-spray eshushu" iinkqubo ze-polyurea.Iinkqubo eziqhelekileyo ze-polyurea ezinevumba elimnandi kufuneka zisetyenzwe ngoxinzelelo oluphezulu, iimpompo zenxalenye yesininzi ezifudunyeziweyo kwaye zitshizwe ngompu wokutshiza wohlobo lwempingement.Oku kuyinyani nakwinguqulelo ye-aliphatic yolu hlobo lwesixokelelwano, umahluko ophambili luzinzo lwemibala yeenkqubo ze-aliphatic.
Imveliso nganye kwiwebhusayithi yethu ineetshathi zokuChasa iiChemical phantsi kwethebhu yamaXwebhu.
Elinye lamahashe ethu okusebenza xa kufikwa kuvezo oluqatha lwekhemikhali yi-SWD959Ngaphaya koko, ukuba unekhemikhali ethile ojongene nayo (okanye isicelo esithile), zive ukhululekileQhagamshelana nathingoko sinokukunceda ukuba ubone eyona nkqubo ilungileyo kwiimfuno zakho.
Sine-urethane yokunyanga ukutyabeka kunye ne-polyaspartic eqinile yokwaleka enomsebenzi ophezulu wokuxhathisa imichiza kwizinyibilikisi, iiasidi okanye ezinye izinyibilikisi.Inokumelana ne-50% H2SO4kunye ne-15% HCL.
Kuxhomekeke ekuqulunqweni, nangona kwimiqulu ethile ye-Shundi, i-polyurea ayiyi kuncipha emva kokuba iphilise.
Nangona kunjalo, lo ngumbuzo olungileyo onokuthi ubuze kuye nabani na okhetha ukuthenga kuye-impahla yakho iyacutheka okanye hayi?
Sinemveliso egqibeleleyo yolu hlobo lwesicelo, i-SWD9005, Le mveliso iye yavavanywa ngokubanzi kwishishini lezimayini, kwaye liye lahlala liqhuba ngaphezu kokulindela.
Ukucwiliswa / ukusetyenziswa kwensimbi, khumbula ukuba i-PUA (i-polyureas) kunye ne-epoxy azifani.Zizo zombini iinkcazo zetekhnoloji / uhlobo lwemveliso.Iinkqubo ze-PUA zisebenza kakuhle ekuntywilisweni, kodwa kufuneka zenziwe ngokufanelekileyo kweso sicelo.
Nangona iinkqubo ze-epoxy zingqongqo kakhulu, iinkqubo ze-PUA zinokuguquguquka okuphezulu kunye namazinga aphantsi okungena kwiinkqubo eziqulunqwe ngokufanelekileyo.I-PUA ikwayimathiriyeli ekhawulezayo yokubuyela kwinkonzo ngokubanzi - i-polyurea iphiliswa ngaphakathi kweeyure xa kuthelekiswa neentsuku (okanye ngamanye amaxesha iiveki) ze-epoxies.Nangona kunjalo, umcimbi omkhulu ngolu hlobo lomsebenzi kunye ne-substrates zensimbi kukuba ukulungiswa komphezulu kubaluleke kakhulu.Oku KUFUNEKA kwenziwe ngokufanelekileyo / ngokupheleleyo.Apha kulapho uninzi luye lwaba nemiba xa bezama ezi projekthi.
Jonga wethuIsiceloamaphepha etyalakwiiprofayile kule kunye nezinye iintlobo ezininzi zezicelo.
Ngokubanzi, umgangatho olungileyo we-100% wepeyinti ye-acrylic latex yendlu isebenza kakuhle kwi-polyurea etshiziweyo.Ngokuqhelekileyo kungcono ukugquma phezu kwe-polyurea (kungekudala kunokuba kamva) kwiiyure ezingama-24 zokufaka isicelo.Oku kukhuthaza ukunamathela okungcono.I-Polyaspartic UV resistance topcoat iyacetyiswa ukuba isetyenziswe ngaphezulu kwe-polyurea ukuze ikwazi ukulwa nokuguga kunye nokumelana nemozulu.
