Timapambana popereka{0}}zapamwamba OEM ndi ODMmayankho kwa anzathu,

kuthandizidwa ndi-ukadaulo wapamwamba komanso ukatswiri wokhoza kupanga.

Simafunikira-kusakanizana pamalopo ndikuchiritsa mu rabara yotanuka kwambiri-monga yolimba potengera chinyezi mumlengalenga. Magulu a urethane mu kapangidwe kake ka mamolekyu amapangitsa kuti zinthuzo zikhale zomatira bwino kwambiri, kukana nyengo, ndi mphamvu yopindika, zomwe zimapangitsa kuti pakhale chotchinga chotchinga pamalumikizidwe omata omwe amaphatikiza kutsekereza madzi, kutulutsa mpweya, komanso kutsekereza ntchito, zoyenera magawo osiyanasiyana komanso malo ovuta. Iyenera kukhala yopanda madzi komanso yosalowetsedwa. Ikachizidwa, imayenera kupanga mosalekeza,{6}}elastomer yosalekeza ndi mayamwidwe amadzi osakwana 0.1%. Pogwiritsa ntchito, imatha kupirira kuthamanga kwa madzi kwa 0.5MPa ndi zaka 10 zamadzi zowonongeka zosakwana 0.2L / min. Kuti azolowere ntchito mankhwala TV, timafuna kuti gawo limodzi polyurethane sealant kugonjetsedwa ndi asidi mvula, mchere kutsitsi ndi dzimbiri mafuta, ndi chaka misa chiwopsezo zosakwana 0.5%. Itha kugwiritsidwa ntchito mosasunthika mu ma asidi osungunuka ndi ma alkali ndi mchere, koma siwolimbana ndi ma acid ndi ma alkali. Ichi ndi chinthu chofunikira chisamaliro.

Ubwino wa ntchito ya gawo limodzi la polyurethane sealant limatsimikizira malo ake ogwiritsira ntchito. Kuchokera kuzinthu zakuthupi mpaka kugwiritsa ntchito mosavuta, ndichifukwa chake amagwiritsidwa ntchito kwambiri:

Kulimba kwamphamvu: Kuposa kapena kofanana ndi 2.5MPa;
Elongation panthawi yopuma: 450% -600%;
Kukana kwanyengo: 85 digiri / 95% RH maola 1000;
Kuchiza nthawi: 24-72 maola (25 digiri);

Ubwino wa-Mapangidwe Amodzi

Ikhoza kutulutsidwa mwachindunji pomanga pogwiritsa ntchito mfuti ya glue, kuthetsa kufunika kosakaniza-zigawo ziwiri, kuchepetsa zolakwika zamanja, ndi kupititsa patsogolo ntchito yomanga (wogwira ntchito m'modzi amatha kupanga 30-50 mamita a mfundo patsiku).

Wide Adhesion

Itha kumangika mwamphamvu ku magawo monga chitsulo, galasi, konkire, miyala, ndi pulasitiki popanda kufunikira koyambira, ndi mphamvu yomatira ya Greater kuposa kapena yofanana ndi 1.5MPa.

Fomu ya Plasticity

Pambuyo pomanga, imatha kukonzedwa pamanja kuti ikhale yosalala kapena yathyathyathya, kugwirizanitsa ntchito yosindikiza ndi kukongola.

Mbali imodzi ya polyurethane sealants imagwiritsidwa ntchito makamaka pama projekiti omanga, kusindikiza zingwe zotchingira khoma ndi madenga otsekereza madzi. M'mapulojekiti oyendetsa, kodi angagwiritsidwenso ntchito pochiza maulalo okulitsa mlatho ndikutsata malo opindika? Pochita, gawo limodzi la polyurethane sealants ntchitoyo imakhudzidwa ndi gawo lapansi, kutentha kozungulira ndi chinyezi, komanso ntchito yomanga. Pa ntchito, pamwamba ayenera kukhala youma kuti mulingo woyenera adhesion.

Kuti mukwaniritse kusindikiza bwino, ndikofunikira kutsatira njira yokhazikika mukamagwiritsa ntchito gawo limodzi la polyurethane sealant. Izi makamaka kuonetsetsa mgwirizano wolimba pakati pa zomatira wosanjikiza ndi gawo lapansi ndi kuchiritsa yunifolomu, potero kukwaniritsa zotsatira zabwino zoletsa madzi.

Kukonzekera

Yang'anani chinyezi chozungulira. Kuchiritsa kwa gawo limodzi la polyurethane sealant kumadalira chinyezi cha mpweya, chomwe chimakhudza kuthamanga kwa machiritso ndi mtundu wake. Chinyezi cha 50% -80% ndichokwanira.

Mchenga

Makamaka pokonza seams akale, chotsani chosindikizira chakale ndiyeno mchenga pansi pa gawo lapansi kuti muchepetse filimu ya oxide pamwamba ndi kumasula wothandizira.

Kuyeretsa

Pukutani fumbi lililonse pamwamba ndi chiguduli, kenaka pukutani mobwerezabwereza ndi chiguduli choviikidwa mu Mowa 2-3 nthawi kuchotsa madontho a mafuta ndi zala.

Kuyanika

Mukatsuka, lolani gawo lapansi kuti liwume kwa mphindi zosachepera 30, kuwonetsetsa kuti chinyontho cha pamwamba ndi Chocheperapo kapena chofanana ndi 8%.

Kugwiritsa ntchito sealant

Kwezani chosindikizira mumfuti, kanikizani mfuti ya plunger kuti mufinyize pang'ono chosindikizira, mutulutse mpweya uliwonse kuchokera ku payipi, ndikusuntha mfutiyo pa liwiro lokhazikika, kusunga mphamvu yokhazikika kuti mutsimikizire kuti sealant imadzaza kusiyana mosalekeza komanso mokwanira, popanda mipata kapena voids.

Kusema wosanjikiza sealant

Ngakhale mbali imodzi ya polyurethane sealant ikadali yonyowa, ipangireni kuti muteteze khungu lomwe silingakonzedwe.
