Kusankha pakati pa polyethylene ndi polypropylene twine kumatha kuwoneka ngati kuthamanga kwa zingwe - zambiri zambiri, kusaleza mtima kokwanira, ndipo mwanjira ina mumangokhala ndi imodzi yomwe imadumpha panthawi yoyipa kwambiri.

Yang'anani pa mphamvu, kukana kwa UV, ndi mtengo wosankha twine yoyenera pantchito yanu. Fananizani zambiri zaukadaulo ndi mayeso ovomerezeka kuchokera kumagwero ngati awaLipoti la ASTM tensile testkuti mufananize magwiridwe antchito ndi zosowa zanu zenizeni zapadziko lapansi.

1. 🧵 Kusiyana kwa kapangidwe kazinthu pakati pa ulusi wa polyethylene ndi ulusi wa polypropylene

Ma polyethylene (PE) ndi polypropylene (PP) amawoneka ofanana, koma mawonekedwe awo a polima amapangitsa kusiyana kowoneka bwino, kachulukidwe, kamvekedwe, komanso magwiridwe antchito anthawi yayitali pamapulogalamu ofunikira.

Kumvetsetsa kusiyana kwazinthu izi kumathandiza ogula kuti agwirizane ndi mtundu wa twine ku zosowa zenizeni zogwirira ntchito, kuyambira paulimi ndi kulongedza katundu kupita kuzinthu zam'madzi ndi chitetezo.

1.1 Mapangidwe a polima ndi kachulukidwe

Polyethylene imasungunuka pang'ono komanso imamveka ngati waxy, pomwe polypropylene ndi yopepuka komanso yolimba. Makhalidwewa amakhudza kagwiridwe ka chitonthozo ndi chitetezo cha mfundo pakugwiritsa ntchito tsiku ndi tsiku.

• PE: kusinthasintha bwino, kulemera pang'ono
• PP: yopepuka kwambiri, yolimba kwambiri

1.2 Mayamwidwe amadzi ndi kukana mankhwala

PE ndi PP zonse zimatenga pafupifupi madzi ndipo zimakana mankhwala ambiri, koma PP nthawi zambiri imapereka kukana bwino kwa ma acid ndi maziko m'mafakitale ovuta.

1.3 Makhalidwe a kutentha ndi malo osungunuka

PP twine amasungunuka pa kutentha pang'ono kuposa PE, kupereka mawonekedwe okhazikika m'malo otentha kapena pafupi ndi zida zotenthetsera zotentha.

1.4 Kumaliza pamwamba ndi utoto

PP twine imatenga mitundu yowala mosavuta ndikuisunga bwino. PE twine nthawi zambiri imakhala ndi malo ofewa, oterera kwambiri omwe amatha kuchepetsa kukangana ndi kuvala.

2. ⚙️ Katundu wamakina: kulimba kwamphamvu, kukhazikika, komanso kufananiza kukana abrasion

Ulusi wa polyethylene nthawi zambiri umapereka kugwirira kofewa komanso kulimba kwabwino, pomwe ulusi wa polypropylene umapereka kuuma kwakukulu komanso kulimba kolimba kolimba pakulemera kochepa kwambiri.

Mainjiniya ndi ogula ayenera kufananiza ma metrics ofunikira monga kuthyola katundu, kutambasula, ndi kukana ma abrasion kuti asankhe njira yotsika mtengo kwambiri.

2.1 Kuyerekeza kwamphamvu kwamphamvu

PP twine nthawi zambiri amapereka mphamvu zamakokedwe apamwamba pa kulemera kwa unit, koma apamwamba PE giredi ndi UHMWPE ulusi akhoza kupitirira muyeso muyezo PP mphamvu.

2.2 Kuthamanga ndi kutalika panthawi yopuma

PE twine nthawi zambiri imatambasula pang'ono isanathyoke, yomwe imathandizira kuyamwa katundu wodabwitsa, pomwe PP twine imasunga utali wokhazikika pansi pazovuta.

• PE: kutalika kwapamwamba, kuyamwa kwabwinoko
• PP: kutalika kwapansi, kuwongolera bwinoko

2.3 Kutupa ndi kukana kutopa

PE ya waxy pamwamba imapangitsa kuti pakhale kutsetsereka ndipo imatha kuchepetsa kuvala, pamene kuuma kwa PP kumathandizira kukana kutopa kwabwino pansi pa kupindika mobwerezabwereza kapena kugogoda.

2.4 Zosankha za PE zogwira ntchito kwambiri

Ultra-high-molecular-weight PE, mongaUHMWPE Fiber (High Performance Polyethylene Fiber) ya Ulusi Wophimba, imapereka mphamvu zapamwamba kwambiri komanso kukana kochepera kuposa PE kapena PP twine.

3. 🌦️ Weatherability, UV kukana, ndi kulimba kwa chilengedwe cha zida zonse ziwiri

Ma twine a PE ndi PP amakana chinyezi ndi mankhwala ambiri, koma kukhazikika kwa UV ndi kulimba kwa nthawi yayitali kwakunja kumasiyana malinga ndi zowonjezera komanso kuwongolera.

Kusankha magiredi okhazikika a UV kumakulitsa kwambiri moyo wautumiki m'malo otetezedwa ndi dzuwa panyanja, ulimi, ndi ntchito zomanga.

3.1 Kukana kwa UV komanso kuwonekera kwa dzuwa

Raw PP ndi PE onse amavutika ndi kuwala kwa dzuwa, koma PE nthawi zambiri imagwira bwinoko pang'ono. Ma UV stabilizer ndi ma pigment amathandizira kwambiri kusunga mphamvu kwa nthawi yayitali.

• Twine yakuda kapena yamitundu imatenga nthawi yayitali panja
• Magiredi okhazikika a UV amachepetsa kusweka ndi kuchoko

3.2 Chinyezi, mchere, ndi kukhalitsa kwa mankhwala

Ma twine onsewa amakana madzi amchere komanso mankhwala ambiri apanyumba, kuwapangitsa kukhala oyenera kusodza, ulimi wam'madzi, ndi ntchito zambiri zamafakitale.

3.3 Kusintha kwa kutentha ndi kukalamba

PE imapambana m'malo ozizira ndipo imakhala yosinthika, pomwe PP imatha kukhala yolimba kwambiri. Onsewa amafunikira zowonjezera zabwino kuti athe kukana makutidwe ndi okosijeni kwa nthawi yayitali komanso kukalamba.

4. 🌍 Zokhudza chilengedwe, kubwezeretsedwanso, ndi kukhazikika pakusankha twine

PE ndi PP onse ndi ma thermoplastics obwezerezedwanso, koma kukonzanso kwapadziko lonse lapansi kumadalira makina am'deralo, mulingo wa kuipitsidwa, ndi zosankha za kapangidwe kazinthu.

Kugwiritsa ntchito ulusi wamphamvu, wokhalitsa kumadula mafupipafupi osinthika ndikugwiritsa ntchito zinthu pa moyo wa chinthu chilichonse.

4.1 Kubwezeretsanso kwa polyethylene ndi polypropylene

Zida zonsezi zitha kubwezeretsedwanso kukhala zinthu zotsika. Zotayidwa zoyera, zosankhidwa ndi mitundu zimawonjezera mwayi wokonzanso bwino pamakina.

4.2 Moyo wautumiki komanso magwiridwe antchito

Mayankho amphamvu kwambiri a PE, kuphatikiza magiredi a UHMWPE, amakhala nthawi yayitali pogwiritsidwa ntchito kwambiri, kuchepetsa zinyalala, ntchito, ndi mphamvu zolumikizidwa ndi kusintha pafupipafupi.

4.3 Kutha kwa moyo komanso nkhawa ya microplastic

Onse PE ndi PP amatha kupanga ma microplastics ngati atasweka panja. Ogwiritsa ntchito apewe kuwotcha panja ndikuthandizira kusonkhanitsa koyenera ndi kubwezeretsanso.

5. 🏭 Kukwanira kwa ntchito ndi kugwiritsa ntchito kovomerezeka, kuwunikira zabwino zazinthu za ChangQingTeng

PE ndi PP twine iliyonse imakhala ndi maudindo omveka bwino pazaulimi, zonyamula katundu, usodzi, chitetezo, ndi misika yamafakitale, kutengera zosowa ndi kuwonekera panja.

Mayankho apamwamba a ChangQingTeng a UHMWPE amawonjezera mphamvu zapamwamba kwambiri, kukana, komanso chitetezo kuposa chingwe chodziwika bwino.

5.1 Kuyika zinthu, ulimi, ndi kumanga

PP twine imakwanira kuwala kwapakati, kuyika udzu, ndi kulongedza wamba, pomwe PE twine imapereka kugwirira kofewa kwa ogwira ntchito komanso kusinthasintha kwanyengo yotsika.

• PP: yotsika mtengo pakugwiritsa ntchito kwakanthawi kochepa
• PE: chitonthozo chabwino komanso kulimba pakuzizira

5.2 Njira zotetezera panyanja, usodzi, ndi zakunja

Kuthamanga kwa PE ndi kusinthasintha kumagwira ntchito bwino m'madzi ndi nyengo yozizira. Zingwe za UHMWPE zimapereka mphamvu zochulukirapo zokhala ndi zotambasulira zochepa kwambiri pantchito zapamadzi zomwe zimafunikira.

5.3 Kugwiritsa ntchito chitetezo chapamwamba komanso chotchinga

Pakuti zida zapamwamba chitetezo, ChangQingTeng amaperekaUHMWPE Rock Fiber Kwa High Cut Level ProductndiUHMWPE Fiber (HMPE FIBER) Yachipolopolo, zomwe zimaposa muyezo wa PE ndi PP mu kudula, kukhudza, ndi kuyamwa mphamvu.

Mapeto

Ulusi wa polyethylene umapereka kusinthasintha komanso kulimba, pomwe polypropylene twine imapereka kulemera kopepuka komanso kuuma. Kusankha kwazinthu kuyenera kuwonetsa kuchuluka kwa katundu, nyengo, ndi mawonekedwe a UV.

Pophatikiza mapangidwe amphamvu ndi ulusi wa UHMWPE wochita bwino kwambiri, ChangQingTeng imathandiza ogwiritsa ntchito kukhala ndi moyo wautali wautumiki, malire otetezeka okwera, komanso mtengo wokwanira wokhala umwini.

Mafunso Omwe Amafunsidwa Kawirikawiri Okhudza Ulusi Wautali Wa Polyethylene

1. Kodi nsonga ya polyethylene ndi yamphamvu kuposa polypropylene twine?

Standard PP twine nthawi zambiri imakhala yamphamvu pa kulemera kwa unit, koma mapepala apamwamba a PE ndi UHMWPE amatha kukhala amphamvu komanso olimba kuposa PP twine.

2. Ndi twine iti yomwe ili yabwino kwa ntchito zakunja ndi zam'madzi?

PE twine nthawi zambiri imachita bwino m'malo ozizira komanso amvula ndipo imakhala yosinthika. UV-stabilized PE nthawi zambiri amakonda kupha nsomba ndi zingwe zam'madzi.

3. Kodi nsonga za polyethylene ndi polypropylene zingagwiritsidwenso ntchito?

Inde, zonse zikhoza kubwezeretsedwanso, koma kupambana kumadalira malo apafupi komanso momwe twine wosonkhanitsidwa aliri woyera. Pewani kuipitsidwa kwambiri kuti muwongolere kukonzanso.

4. Ndi mtundu uti wa twine womwe umapereka chitetezo chabwino cha mfundo?

Kuuma kwa PP kumatha kugwira mfundo zolimba, pomwe malo osalala a PE amatha kutsetsereka ngati mfundo sizikumangidwa bwino. Kusankha mfundo moyenerera ndi kuphunzitsa n'kofunika.

5. Ndi liti pamene ndiyenera kuganizira za UHMWPE ulusi kapena chingwe?

Sankhani mayankho a UHMWPE mukafuna mphamvu zambiri, kutambasula pang'ono, ndi kukana kwambiri, monga zida zotetezera, zotchingira zolemetsa kwambiri, kapena chitetezo champhamvu.
