Kupaka utoto wa polyethylene ndi mapeto otchuka a zitsulo chifukwa cha kulimba kwake, kusinthasintha, ndi kukana mankhwala ndi chinyezi. Komabe, pali zodetsa nkhawa ngati zokutira ufa wa polyethylene ndi poizoni komanso ngati zingawononge thanzi la munthu komanso chilengedwe.

Polyethylene ndi mtundu wa pulasitiki womwe umagwiritsidwa ntchito pazinthu zosiyanasiyana, kuphatikiza kulongedza, kumanga, ndi chisamaliro chaumoyo. Nthawi zambiri amaonedwa kuti ndi zinthu zotetezeka, chifukwa alibe poizoni ndipo alibe mankhwala owopsa. Kupaka utoto wa polyethylene kumapangidwa kuchokera ku zinthu zomwezo ngati pulasitiki ya polyethylene, ndipo nthawi zambiri ndi yabwino kugwiritsa ntchito.

Komabe, pali zinthu zina zomwe zingakhudze chitetezo cha polyethylene ufa wokutira. Chimodzi mwazinthuzi ndi kukhalapo kwa zowonjezera ndi ma pigment omwe amagwiritsidwa ntchito posintha zomwe zimapangidwira. Zina mwa zowonjezera ndi inkiyi zimatha kukhala zapoizoni kapena zovulaza thanzi la munthu komanso chilengedwe, makamaka ngati sizinatayidwe moyenera.

Chinthu china chomwe chingakhudze chitetezo cha polyethylene powder ❖ kuyanika ndi njira yogwiritsira ntchito. Kupaka ufa nthawi zambiri kumagwiritsidwa ntchito ndi mfuti yopopera kapena fluidized bed, yomwe imatha kupanga nkhungu yabwino ya tinthu tating'onoting'ono tomwe timapuma. Ngati kupaka ufa kumakhala ndi zowonjezera kapena inki yapoizoni, kupuma kwa tinthu ting'onoting'ono kumatha kukhala pachiwopsezo ku thanzi la munthu.

Pofuna kuonetsetsa kuti chitetezo cha polyethylene chimanga cha ufa, ndikofunika kugwiritsa ntchito zipangizo zamtengo wapatali zomwe zilibe zowonjezera poizoni ndi ma pigment. Chophimbacho chiyeneranso kugwiritsidwa ntchito moyenera pogwiritsa ntchito njira zoyenera zotetezera, monga kuvala zovala zoteteza komanso kugwiritsa ntchito mpweya wabwino kuti muchepetse chiopsezo cha kupuma.

Kuphatikiza pa zoopsa zomwe zingawononge thanzi la munthu, palinso nkhawa zokhudzana ndi chilengedwe cha zokutira ufa wa polyethylene. Polyethylene ndi zinthu zosawonongeka zomwe zimatha kupitilira chilengedwe kwa zaka zambiri. Ngati kupaka ufa sikutayidwa bwino, kungayambitse kuipitsa ndi kuwononga chilengedwe.

Pofuna kuchepetsa chilengedwe cha polyethylene ufa wokutira, ndikofunika kugwiritsa ntchito zipangizo zachilengedwe zomwe zimakhala zowonongeka kapena zowonongeka. Chophimbacho chiyeneranso kutayidwa moyenera pogwiritsa ntchito njira zoyenera zoyendetsera zinyalala pofuna kuchepetsa chiopsezo cha kuipitsidwa.

Mwachidule, kupaka ufa wa polyethylene nthawi zambiri kumawoneka kuti ndi kotetezeka komanso kopanda poizoni, koma pali zinthu zina zomwe zingakhudze chitetezo chake. Kukhalapo kwa zowonjezera zowopsa ndi inki, komanso njira zosayenera zogwiritsira ntchito, zitha kukhala pachiwopsezo ku thanzi la anthu komanso chilengedwe. Pofuna kuonetsetsa kuti chitetezo cha polyethylene chimanga cha ufa, ndikofunika kugwiritsa ntchito zipangizo zamakono komanso njira zotetezera zoyenera. Mphamvu ya chilengedwe ya zokutira ufa wa polyethylene imathanso kuchepetsedwa pogwiritsa ntchito zida zokomera zachilengedwe komanso njira zoyendetsera zinyalala zoyenera.
