Sealant Testing Process Analysis

Joalo ka thepa ea bohlokoa ea ho tiisa makaleng a kaho, a likoloi le a indasteri, ts'ebetso ea li-sealants e ama boleng ba projeke ka kotloloho le bophelo ba ts'ebeletso. Ho netefatsa ho ts'epahala ha sealant, ba hloka tlhahlobo e felletseng ka mokhoa o hlophisitsoeng oa tlhahlobo.

1. Mohlala oa Boitokisetso le Phekolo ea Pele

Pele ho tlhahlobo, lisampole tsa sealant li tlameha ho lokisoa ho latela litlhaloso tse tloaelehileng. Sena hangata se kenyelletsa ho lokisa substrate (mohlala, ho hloekisa le ho bentša), ho kopanya sekhomaretsi (likarolo tse peli li tlameha ho tsoakoa ka ho lekana ka tekanyo e nepahetseng), le ho etsa (mohlala, ho bopa ka ente kapa ho roala). Mehlala e tlameha ho phekoloa sebakeng se tloaelehileng (mocheso oa 23 ± 2 degree, mongobo 50±5% RH) ka nako e behiloeng (mohlala, lihora tse 24) ho etsisa maemo a sebele a tšebeliso.

2. Teko ea Thepa ea 'Mele

Teko ea Bothata: A Shore A durometer e sebelisoa ho lekanya ho thatafala le bonolo ba sekontiri se phekotsoeng ho netefatsa hore se finyella litlhoko tsa kopo.

Tensile Adhesion: Mochini oa ho etsa liteko o sebelisoa ho lekanya matla a tlamo le bolelele nakong ea khefu pakeng tsa sealant le substrate ho lekola khanyetso ea eona ea ho falla.

Elastic Recovery Rate: Sena se lekanya bokhoni ba colloid hore bo hlaphoheloe ka mor'a ho hatelloa, ho bontša hore ha e khathale ha e sebelisoa{{0}nako e telele.

III. Liteko tsa Lik'hemik'hale le Boemo ba Leholimo

Liteko tsena li kenyelletsa ho hanyetsa mocheso (ho fetoha ha ts'ebetso ka mor'a polokelo e phahameng/tlase ea mocheso), ho se khonehe ha metsi (ho boloka ho khomarela ka mor'a ho qoelisoa), le tlhahlobo ea botsofali ea UV (ho etsisa bosehla kapa chalk e bakoang ke ho khabisoa ha nako e telele-). Lisebelisoa tse ling tse khethehileng li boetse li hloka tlhahlobo ea botsitso ba lik'hemik'hale, joalo ka ho hanyetsa oli le solvent.

IV. Lintho Tse Kotsi le Lipontšo tsa Tikoloho

Ho ea ka melaoana e amehang (joalo ka GB 18583), litaba tsa volatile organic compound (VOC), masalla a tšepe e boima, le mesi ea formaldehyde lia lekoa ho netefatsa hore li tsamaellana le litlhoko tsa tikoloho.

V. Tlhaloso ea Sephetho le Tlaleho

Lintlha tsohle tsa liteko li tlameha ho bapisoa le litekanyetso tsa naha (joalo ka GB/T 14683 le ASTM C920) kapa maemo a indasteri. Tlaleho e hlophisitsoeng e nang le mekhoa ea liteko, maemo le liqeto e tla fanoa ho fana ka motheo oa saense bakeng sa khetho ea thepa.

Ka ts'ebetso ena e tloaelehileng, ts'ebetso ea sealant e ka netefatsoa ka mokhoa o hlophisehileng, ho netefatsa hore e ts'epahala ha nako e telele-ka maemo a rarahaneng.
