UHMWPE Net, kapena ukonde wa polyethylene wolemera kwambiri, ndi nsalu yopangidwa ndi polyethylene wolemera kwambiri (UHMWPE) kudzera mu njira yapadera yolukira. Kulemera kwake kwa mamolekyu nthawi zambiri kumakhala pakati pa 1 miliyoni mpaka 5 miliyoni, kuposa kwa polyethylene wamba (PE), zomwe zimapatsa mphamvu zake zapadera zakuthupi ndi zamakaniko.
Poyamba inali yotchuka chifukwa cha ntchito zake zabwino kwambiri zoteteza komanso kugwiritsa ntchito zinthu zoteteza, UHMWPE Net yakhala ikugwiritsidwa ntchito pang'onopang'ono pazinthu zopangidwa ndi maukonde.UHMWPE Net Zitha kusinthidwa (kuyambira ma micron mpaka masentimita) ndipo zimapezeka kwambiri mumitundu yoyera, yakuda, kapena yowonekera bwino. Zinthu zina zimakhala ndi UV ndi zinthu zotsutsana ndi ukalamba kuti zitsimikizire kuti zikugwirizana ndi malo akunja.
Mphamvu yake yokoka ndi yoposa chitsulo cholemera chofanana nthawi 10 ndipo ndi yokwera pafupifupi 40% kuposa ulusi wa aramid (Kevlar). Komabe, kuchuluka kwake ndi 0.93-0.96 g/cm² yokha.³, yotsika kwambiri kuposa zitsulo ndi ulusi wambiri wogwira ntchito bwino. Chifukwa chake, ngakhale kuti imapereka chitetezo chapadera, imachepetsa kwambiri kulemera konse, zomwe zimapangitsa kuti kukhazikitsa ndi kugwira ntchito zikhale zosavuta.
Pamwamba pake posalala komanso kapangidwe kake kokhazikika ka unyolo wa mamolekyulu kumapereka kukana kwapadera komanso kukana kugwedezeka kuposa kuwirikiza kasanu kuposa polyethylene wamba. Imatha kupirira kukangana mobwerezabwereza komanso kugwedezeka popanda kusweka, ndipo nthawi yake yogwirira ntchito imaposa kwambiri ukonde wachikhalidwe wa nayiloni kapena polyester.
Imalimbana bwino ndi dzimbiri ku ma acid, ma alkali, mchere, ndi zinthu zina zachilengedwe. Imalimbana ndi kukalamba ndi kuwonongeka m'malo okhala ndi chinyezi komanso mchere wambiri (monga m'malo okhala m'nyanja) kapena m'malo oipitsidwa ndi mafakitale, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'njira zosiyanasiyana.
Ngakhale kutentha kotsika kwambiri mpaka -196°C, imasunga kusinthasintha kwabwino komanso kukana kugunda, ndikuchotsa chiopsezo cha kusweka kwa mabala. Imagwiranso ntchito bwino m'malo otentha kwambiri (osakwana 80 ° C).°C). Zopangidwa mwapaderaukonde wa UHMWPE ikhoza kuwonjezeredwa ndi zolimbitsa UV kuti isunge magwiridwe antchito okhazikika ngakhale dzuwa litalowa nthawi yayitali, kuchepetsa ukalamba ndikuwonjezera nthawi yake yogwira ntchito panja.
Chidacho chokha sichili ndi poizoni komanso chopanda vuto, ndipo chikhoza kubwezeretsedwanso (sankhani zitsanzo) mutachitaya, zomwe zimachepetsa kuwonongeka kwa chilengedwe. Sichimayamwanso, sichimalimbana ndi nkhungu, ndipo chimatha kufalikira mosavuta ndi mabakiteriya, zomwe zimapangitsa kuti chigwiritsidwe ntchito m'malo omwe amakhudzidwa ndi chakudya ndi zinthu zam'madzi.
Pogwiritsa ntchito mphamvu zake zazikulu komanso kukana kukwawa, imagwiritsidwa ntchito mu maukonde osodza ndi maukonde a m'madzi. Imatha kupirira kukhudzidwa ndi zamoyo zam'madzi ndi dzimbiri kuchokera m'madzi a m'nyanja, kupititsa patsogolo ntchito yosodza komanso kukonza moyo wa maukondewo. Makonde olerera nsomba: Amagwiritsidwa ntchito mu ulimi wa nsomba za m'madzi akuya kapena a m'madzi oyera, amateteza ku mphepo ndi mafunde, zilombo zolusa (monga shaki ndi mbalame za m'nyanja), ndipo amaonetsetsa kuti madzi akuyenda bwino popanda kusokoneza kukula kwa zamoyo zam'madzi.
Maukonde oteteza kugwa/maukonde oteteza kugwa: Amagwiritsidwa ntchito ngati maukonde oteteza panthawi yomanga ndi ntchito zamlengalenga, kapena kupewa kugwa kwa miyala m'milatho, m'misewu, ndi mapulojekiti ena.
Maukonde oteteza nyama zakuthengo: Amagwiritsidwa ntchito m'malo osungira nyama ndi malo osungira zachilengedwe, amalekanitsa nyama komanso kupewa kuvulala.
Poyerekeza ndi maukonde wamba a polyethylene, amalimba kwambiri ku kugunda kwa mbalame ndi kukokoloka kwa nthaka ndi mphepo, zomwe zimapangitsa kuti akhale oyenera kutetezedwa kwa nthawi yayitali m'minda ya zipatso, m'nyumba zobiriwira, ndi m'malo ena.
Amagwiritsidwa ntchito pothandizira kukwera mipesa (monga mphesa ndi kiwi), amapereka mphamvu yonyamula katundu wamphamvu ndipo amapirira kukalamba.
Monga mipanda ya bwalo la gofu ndi maukonde odzipatula a bwalo la tenisi, amatha kupirira kugwedezeka ndi mipira yothamanga kwambiri ndipo amakhalabe olimba kusinthasintha.
Monga maukonde okwera ndi maukonde oteteza ntchito za m'mlengalenga, kapangidwe kawo kopepuka kamapangitsa kuti zikhale zosavuta kunyamula ndikuyika.
Pogwiritsa ntchito kukana dzimbiri komanso maukonde olondola kwambiri, amagwiritsidwa ntchito kusefa zakumwa kapena zinthu zolimba m'mafakitale a mankhwala ndi migodi.
Zimagwira ntchito ngati chotchinga cha kanthawi kochepa, zimaphatikiza kubisala ndi kukana kukhudzidwa.
UHMWPE Net, ndi ubwino wake wonse wa mphamvu zambiri, kulemera kopepuka, komanso kukana chilengedwe, pang'onopang'ono ikusintha zinthu zakale monga maukonde achitsulo ndi maukonde a nayiloni, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pa ntchito zosiyanasiyana, makamaka pa ntchito zomwe zili ndi zofunikira zolimba pakugwira ntchito kwa zinthu.
