Qalabka ceeriin ee hadda jira ee polyurea waxay inta badan ka kooban yihiin MDI, polyols polyether, polyether polyamines, silsiladaha amine, daroogooyinka kala duwan ee shaqeynaya, midabada iyo buuxinayaasha, iyo dareerayaasha firfircoon. Dahaarka Polyurea waxay leeyihiin sifooyin xawaaraha daaweynta degdega ah, xawaaraha dhismaha degdega ah, ka hortagga daxalka iyo waxqabadka biyuhu, heerkul ballaaran oo kala duwan, iyo habka fudud. Waxay si gaar ah ugu habboon yihiin warshadaha kala duwan ee warshadaha iyo macdanta, meelaha baabuurta la dhigto, garoomada ciyaaraha, iwm., loogu talagalay dahaarka sagxadda oo leh shuruudaha lidka-ka-hortagga, ka-hortagga daxalka iyo xirashada caabbinta.
MUUQAALKA WAX soo saarka
- Dharka caabbinta sare leh, xoqan u adkaysta, adeeg nolol dheer;
- Way ka adag tahay sagxadda epoxy-ga, iyada oo aan dillaacin ama dillaacin:
- Isku-xidhka is-burburinta dusha sare waa mid sarreeya, taasoo ka dhigaysa mid simbiriirixan u adkaysta marka loo eego sagxadda epoxy.
- Samaynta filim hal jaakad ah, qalajin degdeg ah, dhismo fudud oo degdeg ah:
- Dib-u-dabooshadu waxay leedahay adhesion aad u fiican wayna fududahay in la dayactiro.
- Midabada waxaa loo dooran karaa si xor ah. Waa qurux iyo dhalaal. Waa mid aan sun ahayn oo deegaan ahaan u wanaagsan.
Hababka dhismaha
Biyo-celinta saqafka
Dusha saqafka fidsan [Biyo-ilaalinta joogtada ah ee isboortiska]
Saqafka jilcan, habka dhismaha aasaaska foornada
- 1. Nadiifi siigada, hagaaji dusha sare si aad u nadiifiso oo nadiif u noqoto. Haddii ay jiraan taayirro kor loo qaaday, la beddelay ama dhaawacmay, waxay u baahan yihiin in dib loo dhigo. Tiirarka jajaban iyo meelaha banaan-baxa waaweyn leh waa in lagu daaweeyaa malaasayt si loo adkeeyo tiirarka oo aan debecsaneen, lana kulmaan shuruudaha dhismaha.
- 2. Qaad tallaabooyinka ilaalinta, isticmaal bacaha si aad u ilaaliso alaabta saqafka sare ah iyo agagaarkeeda, sida nalalka samada, fiilooyinka, muraayadaha cadceedda, baabuurta, iwm.
- 3. Dul mari/ mari furaha khaaska ah ee poliurea si aad u xidho daloolada dusha sare ee saldhiga, adoo kordhinaya awooda isku xidhka dhexda
- 4. Ku buufi sheyga elastomer-ka ee polyurea oo ah lakabka muhiimka ah, adoo diiradda saaraya maaraynta tafaasiisha sida cirifka, tiirarka dhinac-yada, geesaha, marinnada, daadadka, iwm.
- 5. Dul mari/ mari jaakada sare ee gaarka ah ee poliurea, ka dhigaysa mid qurux badan, u adkaysanaysa cimilada, oo aan isbeddelayn midabka.
Beerta Biyaha
- 1. Daawaynta aasaasiga ah: Ka saar lakabka slurry salka oo qaawin dusha adag ee salka. Hubi in aasaasku uu gaadho darajo C25 ama ka badan, siman oo engegan, boodh la'aan, oo aanu dib ciid u samayn. Haddii ay jiraan awlallo malabka, sagxadaha qallafsan, dildilaaca, iwm, ka dib isticmaal qalabka dayactirka si aad u hagaajiso oo aad u simiso si aad u hubiso adkeysiga.
- 2. Codsiga asaasiga ah ee polyurea: Si siman u mari poliurea-ga gaarka ah ee aasaaska si aad u xirto daloolada xididka ee dusha sare, kor u qaad qaab dhismeedka dhulka, yareyso cilladaha daahan ka dib buufinta, iyo kordhinta adhesion u dhexeeya poliurea putty iyo sibidhka, dhul shub ah. Sug ilaa inta ay si buuxda u bogsanayso ka hor intaadan u gudbin tallaabada xigta. Haddii ay jirto caddaymo ballaaran ka dib codsiga, waxay u baahan tahay in dib loo codsado ilaa dhulka oo dhan uu ka soo muuqdo brown madow.
- 3. Codsiga suufka polyurea: Si siman u mari polyurea-ga u dhigma xiniinyaha gaarka ah si aad u kordhiso fidsanaanta dhulka, xidh daldaloolada xididada ee aan indhaha qaawan arkin, kana fogow xaalada ay polyurea la buufiyo ay leedahay godad ay sabab u tahay daloolada xididada dhulka. Sug ilaa inta ay si buuxda u bogsanayso ka hor intaadan u gudbin tallaabada xigta.
- 4. Codsiga asaasiga ah ee polyurea: Si siman ugu mari poliurea primer putty poliurea ee la daweeyay si aad si wax ku ool ah u kordhiso xabagta u dhaxaysa lakabka polyurea ee la buufiyay iyo polyurea putty.
- 5. Ku buufi codsiga polyurea: 24 saacadood gudahood ka dib daawaynta asaasiga ah, isticmaal qalabka buufinta xirfadleyda si aad si siman ugu buufiso poliurea. Dusha sare ee dahaarka waa in ay ahaataa mid siman, iyada oo aan la bixin, godad, goobooyin, ama dildilaac la'aan; Burburka deegaanka ama godad fiiqan, dayactirka gacanta polyurea ayaa loo isticmaali karaa.
- 6. Codsiga dusha sare ee polyurea: Ka dib marka dusha sare ee poliurea qallajiso, mari poliurea topcoat si looga hortago gabowga, midabaynta, iyo kor u qaadida caabbinta xirashada ee poliurea, ilaalinta xuubka poliurea.
