Ndi mitundu yanji ya zingwe zazitali za polyethylene?

Zingwe zikadali zofala kwambiri m'moyo, koma anthu ambiri samamvetsetsa bwino za ntchito zina zazing'ono za zingwe.Ndipotu, pali mitundu yambiri ya zingwe, kutengera ntchito:

1. Chingwe chosasunthika, chomwe chimadziwikanso kuti chingwe choyera, chimagwiritsidwa ntchito pofufuza phanga.Ngakhale kuti elasticity ndi yotsika kwambiri, imakhala ndi mphamvu yokana kuvala.

2. Zingwe zamphamvu zimatchedwanso zingwe zamaluwa ndi zingwe zoluka.Amagwiritsidwa ntchito ngati chinthu chofunikira pakukwera masewera kapena kukwera kwaupainiya.Amakhala ndi elasticity yapamwamba, koma ndi okwera mtengo.).

3. Chingwe champhamvu (mankhwala osalowa madzi) chimagwiritsidwa ntchito kwambiri potsata pafupifupi 10mm-11mm ndi m'mimba mwake pafupifupi 10mm-11mm.

4. Zingwe za m'madzi zimagwiritsidwa ntchito poyendetsa sitima zapamadzi.Kuphatikiza pa kulemera kopepuka, mphamvu yayikulu, kukana kwamphamvu komanso kukana kuvala, chingwe cha nayiloni chilinso ndi zabwino zokana dzimbiri, kukana kwa mildew ndi kukana njenjete.Mwachitsanzo, mphamvu ndi kupsa mtima kwa zingwe za nayiloni ndi kangapo kuposa zingwe za thonje, ndipo gawo la zingwe za nayiloni ndi laling'ono kuposa la madzi, kotero kuti likhoza kuyandama pamwamba pa madzi, omwe ndi abwino komanso otetezeka kugwira ntchito. .Malinga ndi kapangidwe kake, zingwe zama fiber zimatha kugawidwa m'magulu atatu, zingwe zamitundu yambiri ndi 8-strand, zingwe zamitundu yambiri.Kutalika kwa chingwe cha zingwe zitatu nthawi zambiri kumakhala 4 ~ 50mm, ndipo m'mimba mwake chingwe cha zingwe zisanu ndi zitatu nthawi zambiri chimakhala 35 ~ 120mm.Kuphatikiza pa zingwe zam'madzi, maukonde a chingwe chamankhwala amagwiritsidwanso ntchito kwambiri pamayendedwe, mafakitale, migodi, masewera, usodzi ndi zina.

Chifukwa cha kusungirako kosautsa kwa chingwe, sizitsulo zodziwika bwino za chingwe;pewani njira zolakwika zogwiritsira ntchito monga kuwala kwa dzuwa, asidi (zotsukira zopanda ndale), nkhanza (SM kapena chingwe), nthawi zambiri amaika chingwe m'chikwama chochapira, kuponyera mu makina ochapira, ikani Onjezani zotsukira zosalowerera, kutsuka, kenaka. youma pamthunzi.Posonkhanitsa zingwe ndi zingwe, khungu ndi kupotoza kwa chingwe ziyenera kutsimikiziridwa mosamala.Khungu likasweka kapena ma stamens atuluka, ayenera kudulidwa ndikubwezeretsanso.Podula chingwe, gwiritsani ntchito tepi kumapeto onse a malo odulidwa, ndipo mutatha kudula, zingwe za stamens zimaphatikizidwa ndi moto.
