Sealant Testing Process Analysis

Sechinhu chakakosha chekuisa chisimbiso muzvikamu zvekuvaka, zvemotokari, uye maindasitiri, kuita kwezvisimbiso kunokanganisa zvakananga kunaka kweprojekiti uye hupenyu hwebasa. Kuti ive nechokwadi chekuvimbika kwechisimbiso, ivo vanoda kuongororwa kwakazara kuburikidza nehurongwa hwekuyedza maitiro.

1. Sample Kugadzirira uye Pretreatment

Usati waedzwa, sealant samples dzinofanirwa kugadzirirwa zvinoenderana neyakajairwa yakatarwa. Izvi zvinowanzobatanidza kugadzirira substrate (semuenzaniso, kucheneswa nekupukuta), kusanganiswa kwenamira (izvo zviviri zvinofanirwa kusanganiswa zvakaenzana muchiyero chaidzo), uye kugadzira (semuenzaniso, kuumba jekiseni kana kupeta). Samples dzinofanirwa kurapwa munzvimbo yakajairika (tembiricha 23±2 degree, humidity 50±5% RH) kwenguva yakatarwa (semuenzaniso, maawa makumi maviri nemana) kutevedzera mamiriro chaiwo ekushandisa.

2. Kuongororwa Kwezvinhu Zvenyama

Kuomarara Kuedzwa: Iyo Shore A durometer inoshandiswa kuyera kuomarara uye kupfava kwechisimbiso chakarapwa kuti ive nechokwadi chekuti inosangana nezvinodiwa zvekushandisa.

Tensile Adhesion: Muchina wekutemesa wekuyedza unoshandiswa kuyera kusimba kwechisungo uye kureba panguva yekupwanya pakati pechisimbiso uye substrate kuongorora kuramba kwayo kutamiswa.

Elastic Recovery Rate: Izvi zvinoyera kugona kwecolloid kupora kubva pakukanganiswa mushure mekudzvanyirirwa, zvichiratidza kusaneta kwayo panguva-yekushandisa kwenguva refu.

III. Kemikari uye Weathering Miedzo

Miedzo iyi inosanganisira kuramba tembiricha (kushanduka kwemaitiro mushure mekuchengetedza tembiricha yepamusoro/yakaderera), kusamira kwemvura (kunamira kana kunyudzwa), uye kuongorora kuchembera kweUV (kutevedzera kutsvuka kana kuti chalk kunokonzerwa ne-kuratidzwa kwechiedza kwenguva refu). Mamwe maapplication akakosha anodawo kuyedzwa kugadzikana kwemakemikari, senge oiri uye zvinonyungudutsa kuramba.

IV. Zvinhu Zvinokuvadza uye Zviratidzo zveNzvimbo

Zvinoenderana nemirairo yakakodzera (senge GB 18583), volatile organic compound (VOC) zvemukati, zvinorema simbi zvakasara, uye formaldehyde emissions zvinoedzwa kuti ive nechokwadi chekutevedzera zvinodiwa kwezvakatipoteredza.

V. Tsanangudzo uye Kushuma

Yese data rekuyedza rinofanirwa kuenzaniswa nezviyero zvenyika (senge GB/T 14683 uye ASTM C920) kana indasitiri zviyero. Chirevo chepamutemo chine nzira dzekuyedza, mamiriro, uye mhedziso zvichapihwa kupa hwaro hwesainzi hwekusarudzwa kwezvinhu.

Kuburikidza nemaitiro aya akaenzana, kuita kwechisimbiso kunogona kunyatso tsinhirwa, kuve nechokwadi chekuti{0}}yakavimbika kwenguva refu munzvimbo dzakaoma kunzwisisa.
