Izimpawu Eziyisisekelo kanye Nemisebenzi Ebalulekile Yezingxenye Ezimbili-ze-Silicone Sealant

Izingxenye ezimbili-ze-silicone sealant ziyingxube yengxenye A (i-base adhesive) kanye nengxenye B (elaphayo) elapha ngemva kokuxuba. Imisebenzi yayo eyinhloko ingafingqwa kanje:

1. Okuphezulu-Ukubopha Amandla: Amandla ebhondi ezintweni ezifana nengilazi, insimbi, nokhonkolo angafinyelela ku-1.5-2.5 MPa (ngokuya nge-GB/T 14683-2017), edlula kude i-0.8-1.2 MPa yemikhiqizo yengxenye eyodwa, okuyenza ifaneleke ngokukhethekile ukuhlanganisa inhlanganisela yesakhiwo.

2. Ukuzinza Ezimweni Eziphakeme Kakhulu: Ngebanga lokushisa elingu--60℃kuya ku-200℃kanye nempilo yesevisi engaphezu kweminyaka engu-20 ngaphansi kokuchayeka kwe-UV (idatha yokuhlola ye-ASTM C794), ilungele izinhlelo zokusebenza ezifana nezindonga zamakhethini angaphandle namajoyinti okunwetshwa kwebhuloho.

3. Isinxephezelo Sokufuduka Okunamandla: Ngezinga lokutakula elinwebekayo Lokukhulu noma elilingana no-90% (izinga le-ISO 9047), lingakwazi ukumelana nokususwa kwamalungu angu-±50%, libhekane nokuqhekeka okubangelwa ukwanda nokufinyela okushisayo ezakhiweni.

4. Ukuvikelwa kokungangeni kwamakhemikhali: Imelana ne-asidi, i-alkali nokugqwala kwesifutho sikasawoti, okuvamise ukusetshenziselwa ukuvala amapayipi ezitshalweni zamakhemikhali noma ukuvikelwa kwezinto zasolwandle.
