Momwe mungathetsere vuto la mzere wotseguka wamatumba opaka pulasitiki?

Pakupanga matumba oluka, nthawi zina padzakhala ulusi wotseguka, womwe umabweretsa zovuta pakuyika ndi zinthu.Wopanga zikwama zapulasitiki zoluka amati akamasoka zikwama zapulasitiki, singanoyo imatsogolera ulusi wapamwamba m’thumba.Ikafika pamtunda wocheperako, imapita patsogolo.Chifukwa cha mkangano wa ulusi wosokera ndi suture, ulusi wapamwamba sungathe kusokedwa mwachisawawa.Patsogolo synchronously, koma khalani pansi pa zosokera, ndipo pansi pa mphamvu ya elasticity, izo zimapanga lupu kumbali zonse za singano.

Kenako nsonga ya mbedza imafika pa singano yamakina panthawi yosuntha, kotero kuti ulusiwo umadutsa, ndipo pakusintha kosalekeza, ulusi wokokera umakulitsidwa, ndipo ikakulungidwa ku radius yake, imawoloka ulusi wokulirapo. lupu, Kenako chingwe chotengera ulusi chimatenga ulusiwo, ndipo galu amadyetsa zinthuzo.Kuti izi zitheke bwino komanso mosadodometsedwa, mbedza imapitilirabe kusinthasintha pa liwiro loyambirira la bwalo limodzi, m'malo mochita mozungulira bwalo limodzi mutakoka ulusi.Pambuyo singano kufika kumtunda malire udindo, pamene ulusi anatsogolera pansi kachiwiri , Pulasitiki nsalu thumba kusoka makina mkombero wotero, angathe kuthetsa mavuto pamwamba.

Malinga ndi gulu la zipangizo, matumba pulasitiki nsalu ndi zosavuta kusiyanitsa.Chimodzi ndi matumba opangidwa ndi polypropylene ndipo china ndi matumba a polyethylene.Matumba awiri apulasitiki olukidwa azinthu zosiyanasiyana ali ndi mbali ndi ntchito zosiyanasiyana, ndipo Z ndi matumba opangidwa ndi Polypropylene amagwiritsidwa ntchito kwambiri.Zida zopangira matumba oluka zimayikidwa pang'onopang'ono asanapange thumba, ndipo gawo lowoneka ngati laling'ono koma lovuta kwambiri ndikujambula mawaya.

Ngakhale zikuwoneka zophweka, khalidwe lajambula lawaya limakhudza mwachindunji ndikuwonetsa ubwino wa mphamvu yokoka ya thumba la pulasitiki.Kuyesa kwa matumba oluka kumatenga nthawi yayitali ndipo kumafuna anthu ambiri komanso ndalama, koma zoyeserera zomwe zapezedwa zimakwaniritsa zofunikira zenizeni zogwiritsiridwa ntchito ndipo zitha kugwiritsidwa ntchito poyesa kuwunika kwa odana ndi ukalamba komanso kuwunika koletsa kukalamba. matumba oluka.
Kwa matumba oluka, ndikofunikira kuchotsa magetsi osasunthika omwe amapangidwa panthawi yopanga.Kupatula apo, matumba oluka ndi mtundu wazinthu zapulasitiki.Ngati magetsi osasunthika sachotsedwa bwino, angayambitse zovuta zazikulu monga moto.Musanayambe kupanga matumba apulasitiki opangidwa ndi pulasitiki, njira yojambula ndiyofunikira.

Chifukwa kokha popota pulasitiki poyamba, chikwama cholukidwa chingapangidwe pa nsalu yozungulira.Matumba opangidwa ndi pulasitiki amapangidwa ndi matumba a polypropylene ndi matumba a polyethylene malinga ndi zida zazikulu;molingana ndi njira yosoka, amagawidwa m'matumba apansi otsekedwa ndi matumba apansi otsekedwa.Pakalipano, amagwiritsidwa ntchito kwambiri ngati zopangira zopangira feteleza, mankhwala ndi zinthu zina.
