Iingenelo zePolyurethane Foam Caulking
1. Ukusebenza kakuhle kunye nokonga amandla, akukho zikhewu emva kokuzaliswa, kunye nokubopha okuqinileyo emva kokunyanga.
2. Ayinawohloki kwaye iyacinezela, kwaye ayizukuqhekeka, ibole, okanye iwe emva kokuba inyangiwe.
3.Inobushushu obuphantsi kakhulu, ukumelana nemozulu kunye nokugcinwa kobushushu.
4. Ubushushu obuphezulu, ubushushu obuphezulu, obungangeni manzi kwaye obungangeni manzi emva kokunyangwa.
Yintoni ekufuneka iqwalaselwe ngexesha lokwakha?
Ubushushu obuqhelekileyo bokusetyenziswa kwe-polyurethane foam yi +5~+40℃, kwaye ubushushu obufanelekileyo bokusetyenziswa yi +18~+25℃. Kwimeko yobushushu obuphantsi, kucetyiswa ukuba uyibeke kubushushu obungaguqukiyo be +25 ukuya kwi +30 °C imizuzu engama-30 ngaphambi kokuba uyisebenzise ukuqinisekisa ukusebenza kwayo okuphezulu. Uluhlu lokumelana nobushushu be-polyurethane foam evunyiweyo yi -35℃～+80℃.
I-polyurethane foam yi-foam ephilisa umswakama kwaye kufuneka itshizwe kwiindawo ezimanzi xa isetyenziswa. Okukhona umswakama uphezulu, kokukhona i-filling ikhawuleza. I-foam engacocwanga ingacocwa ngee-agents zokucoca, ngelixa i-foam ecociweyo isuswa ngeendlela zoomatshini (ukuyigquma okanye ukuyisika). I-foam ecociweyo iya kuba tyheli xa ivezwe kukukhanya kwe-ultraviolet. Kucetyiswa ukuba ugqume umphezulu we-foam ecociweyo ngezinye izinto (isamente yesamente, ipeyinti, njl.njl.). Emva kokusebenzisa i-spray gun, nceda uyicoce nge-agent ekhethekileyo yokucoca ngoko nangoko. Xa utshintsha itanki yezinto, shukumisa itanki entsha kakuhle (ubuncinane amaxesha angama-20), susa itanki engenanto, kwaye utshintshe itanki entsha yezinto ngokukhawuleza ukuthintela uqhagamshelo lwe-gun ekupheliseni.
Ivalvu yokulawula ukuhamba kwamanzi kunye ne-trigger ye-spray gun zilawula ubungakanani bokuhamba kwamanzi kwi-foam. Vala ivalvu yokuhamba kwamanzi kwicala elijikajikayo xa ukutshiza kuyeka.
