ZINTHU ZONSE ZONSE

Njira zogwiritsira ntchito silicone sealant ndi nthawi yochiritsa

Silicone sealant ndi zomatira zofunika, zomwe zimagwiritsidwa ntchito makamaka kulumikiza magalasi osiyanasiyana ndi magawo ena. Amagwiritsidwa ntchito kwambiri m'moyo wabanja, ndipo pali mitundu yambiri ya zosindikizira za silikoni pamsika, ndipo mphamvu zomangira za ma silicone sealants nthawi zambiri zimawonetsedwa. Kotero, momwe mungagwiritsire ntchito silicone sealant? Zimatenga nthawi yayitali bwanji kuti silicone sealant ichire?

Njira zogwiritsira ntchito silicone sealant

1.Chotsani chinyezi, mafuta, fumbi ndi zowononga zina pamwamba pa zinthu. Ngati kuli koyenera, gwiritsani ntchito zosungunulira (monga xylene, butanone) kuyeretsa pamwamba, ndiyeno gwiritsani ntchito chiguduli choyeretsa popukuta zotsalira zonse kuti zikhale zaukhondo ndi zouma.

2.Kuphimba pamwamba pafupi ndi mawonekedwe ndi tepi ya pulasitiki. Kuonetsetsa kuti mzere wa ntchito yosindikiza ndi wangwiro komanso mwadongosolo.

3.Dulani payipi yosindikiza pakamwa ndikuyika chitoliro cha nozzle choloza. Ndiye malinga ndi kukula kwa caulking, imadulidwa pa 45 ° Angle.

4.Ikani mfuti ya glue ndikusindikiza zinthu zomatira pamphepete mwa 45 ° Angle kuti muwonetsetse kuti guluu likugwirizana kwambiri ndi zinthu zapansi. Pamene msoko m'lifupi ndi wamkulu kuposa 15 mm, mobwerezabwereza gluing chofunika. Mukatha gluing, chepetsani pamwamba ndi mpeni kuti muchotse guluu wowonjezera, kenako ndikudula tepiyo. Ngati pali madontho, chotsani ndi nsalu yonyowa.

5.sealant kutentha kutentha pambuyo pa mphindi 10 za vulcanization pamwamba, vulcanization wathunthu amatenga maola 24 kapena kuposa, malinga ndi makulidwe a zokutira ndi kutentha ndi chinyezi chilengedwe.

Silicone sealant nthawi yochiritsa

Silicone sealant yomatira nthawi ndi nthawi yochiritsa:

Silicone sealant kuchiritsa ndondomeko amapangidwa kuchokera pamwamba mpaka mkati, makhalidwe osiyana a sealant pamwamba pa nthawi youma ndi kuchiritsa nthawi si ofanana, kotero ngati mukufuna kukonza pamwamba ayenera kuchitidwa pamaso sealant pamwamba youma. Pakati pawo, guluu wa asidi ndi guluu wosalowerera ndale ayenera kukhala mkati mwa mphindi 5-10, ndipo guluu wamitundu yosiyanasiyana uyenera kukhala mkati mwa mphindi 30. Ngati pepala lolekanitsa mtundu likugwiritsidwa ntchito kuphimba malo enaake, mutatha kugwiritsa ntchito guluu, liyenera kuchotsedwa khungu lisanapangidwe.

Kuchiritsa nthawi ya silicone sealant (pa kutentha kwa 20 ° ndi chinyezi cha 40%) kumawonjezeka ndi kuwonjezeka kwa makulidwe omangira. Mwachitsanzo, 12mm wandiweyani asidi silikoni sealant zingatenge masiku 3-4 kuti akhazikike, koma pasanathe maola 24, wosanjikiza 3mm kunja kwachira. Ngati malo omwe chisindikizocho chimagwiritsidwa ntchito pang'ono kapena kutsekedwa kwathunthu, ndiye kuti nthawi yochiritsa imatsimikiziridwa ndi kulimba kwa chisindikizo. Muzochitika zosiyanasiyana zomangirira, kuphatikizapo mpweya wotsekemera, zotsatira zomangira ziyenera kuyang'aniridwa bwino zida zomangira zisanagwiritsidwe ntchito. Kuchiritsa kumachepetsa kutentha kwapansi (pansi pa 5 °) ndi chinyezi (pansi pa 40%).
