Zolumikizira zingwe zamagetsi zimagawidwa kukhala + cholumikizira, - cholumikizira, ndi cholumikizira T. Zolumikizana ziyenera kulumikizidwa, zosalala, komanso zosafunikira. Kodi njira zolumikizira zingwe ndi ziti? Kodi njira zopangira ma chingwe osalowa madzi ndi ziti?
1. Njira yolumikizira chingwe
Zolumikizira zingwe zamagetsi zimagawidwa kukhala + cholumikizira, - cholumikizira, ndi cholumikizira T. Seams ayenera kukhala ovulala, osalala komanso osafunikira. Kumapeto kwa waya ndi kuchotsedwa, pang'onopang'ono akanikizire waya achepetsa, ndiye mphepo kuzungulira pakamwa, ndiye kugwedezeka kumanzere ndi kumanja, ndiyeno kulumikiza mapeto a waya ndi cholumikizira kusagwirizana. Ngati olowa ali pamalo owuma, ayenera wokutidwa ndi zigawo ziwiri za insulating nsalu wakuda, ndiye zigawo ziwiri za tepi pulasitiki (wotchedwanso PVC tepi), ndiye zigawo ziwiri kapena zitatu za J-10 insulating kudziona zomatira tepi anatambasula. pafupifupi 200%, ndipo potsiriza zigawo ziwiri za tepi ya pulasitiki.
Chifukwa mwachindunji ntchito pulasitiki ndi kuipa ambiri: pulasitiki tepi zosavuta kubala guluu dislocation, guluu lotseguka; Pamene katundu wamagetsi ndi wolemetsa, chophatikiziracho chimakhala chotentha, mzere wa pulasitiki ndi wosavuta kusungunuka ndi kuchepa; Zolumikizira mphamvu zimapanikizidwa pamodzi mubokosi lolumikizirana. Pamene zolumikizira zili burr, ndikosavuta kugwedeza matepi apulasitiki. Zowopsa zobisika izi zimayika mwachindunji chitetezo chamunthu pachiwopsezo, kupanga mzere wocheperako, kuyambitsa moto. Komabe, ntchito insulating wakuda tepi sizidzachitika, ali ndi mphamvu inayake, kusinthasintha, akhoza atakulungidwa mu msoko kwa nthawi yaitali, malinga ndi nthawi ndi kutentha ndi youma zokhazikika mtundu, sadzakhala kugwa, ndi lawi retardant.
Kuphatikiza apo, tepi yomatira imatha kukhala yotsimikizira chinyezi komanso dzimbiri itakulungidwa ndi tepi yakuda yoteteza. Kumene, kutchinjiriza kudziona zomatira tepi alinso ndi zilema, ngakhale ndi ntchito yabwino madzi, koma zosavuta kuthyoka, kotero potsiriza ndi zigawo ziwiri za tepi pulasitiki wokutidwa ngati wosanjikiza zoteteza, olowa wa kutchinjiriza kudziona zomatira tepi ndi olowa. musamamatirane, ntchitoyo ndi yabwino.
