Kodi chingwe cha polyethylene cholemera kwambiri cha molekyulu chingasinthidwe pati?

Zingwe ndi zingwe zimagwiritsidwa ntchito makamaka pakukonza zombo, kusodza, kutsitsa ndikutsitsa pamadoko, kumanga mphamvu zamagetsi, kufufuza mafuta, chitetezo cha dziko ndi makampani ankhondo, katundu wamasewera ndi zina.Mapangidwe ake amagawidwa mu zingwe zitatu, zisanu ndi zitatu ndi khumi ndi ziwiri.Mankhwalawa amagwiritsidwa ntchito kwambiri ndipo ali ndi makhalidwe amphamvu kwambiri, kuwonjezereka kochepa, kukana kuvala, kufewa ndi kusalala, ndi ntchito yosavuta.

Njira zodzitetezera pakugwiritsa ntchito chingwe: Musanagwiritse ntchito, yang'anani mosamalitsa zolembera, zolemba, zolowetsa m'maso, ndi thupi la chingwe kuti mudulidwe, zingwe zosweka, mawaya othyoka, mfundo ndi zina zowonongeka.Ngati palibe zolakwika ndi zolakwika, zitha kugwiritsidwa ntchito moyenera;pomasula chingwecho, tulutsani chingwecho kuchokera kumapeto kwa chingwe mu bwalo, chingwecho chiyenera kumasulidwa mozungulira.

Kumangirira kwa chingwe kumachitika ngati chingwecho sichivulazidwa motsatira koloko.Ngati mfundo ya batani yapangidwa, ikani chingwecho mu lupu, zungulirani chingwecho, ndi kukokera chingwecho pakati.Njira yabwino ndiyo kumasula chingwe pa turntable.Panthawiyi, chingwecho chikhoza kutulutsidwa kuchokera kumapeto kwa chingwe chakunja.Ngati anthu aima mwamphamvu kwambiri pansi pa chingwe, pali ngozi.Chingwecho chikapanda kuwongolera, chidzabweretsa kupsinjika kwakukulu, komwe kungathe kuvulaza.

Ngati chingwecho sichikuvulazidwa kuchokera ku spool, spool yokha iyenera kuzungulira momasuka.Izi ndizosavuta kuchita ndi chitoliro pakati pa spool, koma ndizoletsedwa kuyika spool molunjika kuti mutulutse chingwe;ngati chingwe sichivulazidwa ndi kapu, chiŵerengero cha m'mimba mwake D cha kapuli mpaka m'mimba mwake D cha chingwe chiyenera kupitirira 5, koma ulusi wina wochita bwino kwambiri uyenera kufika pa 20.

Kwa zingwe, tikulimbikitsidwa kuti m'mimba mwake wa pulley groove ikhale 10% -15% yayikulu kuposa kukula kwa chingwe.Ngati arc ya chingwe cholumikizana ndi pulley groove ndi madigiri 150, chingwechi chikhoza kufika kupsinjika kwabwino, ndipo kutalika kwa bwana wa pulley kuyenera kukhala osachepera 1. Kuti chingwe chisathe kutha nthawi 5 m'mimba mwake. puli.Kuphatikiza apo, yang'anani pulley pafupipafupi ndikusunga zonyamula pafupipafupi kuti muwonetsetse kuti pulley imazungulira bwino.

Chingwecho chiyenera kuchotsedwa kapena kuchotsedwa ntchito pazochitika zotsatirazi: chingwe chikuwoneka chopsa kapena kusungunuka;mtunda wozungulira ndi wofanana ndi kutalika kwa chingwe, ulusi wa chingwe pamwamba kapena kuchuluka kwa chingwe kumachepetsedwa ndi 10%;chingwecho chimawonekera kumadera otentha kwambiri kupitirira malire;Kuwonekera kwa UV Kuchepa, zinyalala zopangidwa pamwamba pa chingwe;chingwe anaonekera kwambiri kuonongeka otentha kusungunuka, olimba ndi wosweka madera;kusungunuka kapena kugwirizana kunakhudza zoposa 20% ya chingwe.
