Chingwe cha PET (chingwe cha poliyesitala) chimachokera ku kulemera kwa molekyulu ya zinthu zake zopangira, zomwe zimayesedwa ndi intrinsic viscosity (IV). Mtundu wa IV wamalamba apamwamba kwambiri a PET ndi 0.60 mpaka 0.95 dl/g.

Chingwe cha PET (chingwe cha poliyesitala) chalowa m'malo mwa zomangira zitsulo m'mapaketi ambiri, ndikupatsa mphamvu zofananirako pa gawo limodzi mwa magawo asanu ndi limodzi a kulemera kwake, popanda dzimbiri, m'mbali zakuthwa, ndi 30-50% kutsika mtengo wonse. Koma kodi chingalowe m'malo mwachitsulo kwathunthu? Yankho ndilakuti: m'mapulogalamu ambiri, inde, koma osati onse.

Chingwe cha PET (chingwe cha polyester) chimakwaniritsa mphamvu zopumira kuyambira 160kg mpaka 1,360kg kutengera m'lifupi ndi makulidwe. Izi zimagwiranso ntchito kuyambira pakunyamula pallet zopepuka mpaka kumangirira zitsulo zolemera zachitsulo ndi zopaka thonje. Kuphwanyidwa kwa mphamvu kumatsimikiziridwa ndi chigawo chozungulira cha chingwe ndi momwe ma molekyulu amayendera popanga.

Zogulitsa za aluminiyamu - ma ingot, makoyilo, mbiri, ndi mapepala - zimakhala ndi zovuta zoyikapo zomwe zingwe wamba sizingathane nazo. Zolemera zolemera, m'mbali zakuthwa, kukhudzika kwa pamwamba, kusungirako panja, ndi zomangira zapanyanja zokhala ndi mphamvu zolimba kwambiri, zotalikirapo pang'ono, kuchita kosachita dzimbiri, komanso kukana nyengo.

Chingwe cha PET (chingwe cha poliyesitala) chakhala njira yamakono yomangira zitsulo m'mafakitale ambiri kuyambira pakukonza zitsulo mpaka kukumba thonje. Amapereka mphamvu zomangika ngati chitsulo pa gawo limodzi mwa magawo asanu ndi limodzi a kulemera kwake, amachotsa ziwopsezo zovulaza kuchokera m'mbali zakuthwa ndi snap-back, komanso kukana dzimbiri ndi dzimbiri.

Chingwe cha PET (chingwe cha poliyesitala) chimakhala ndi moyo wosungira bwino wa miyezi 18-36 pansi pamikhalidwe yoyenera. Kutentha, chinyezi, kuwonekera kwa UV, ndi kukhulupirika kwa phukusi zonse zimakhudza kutalika kwa chingwe cha PET.

Kuyika kwamakampani olemera kumafuna zomangira zomwe zimakhazikika pansi pazovuta, zimalimbana ndi abrasion, ndikupulumuka kusungidwa kwakunja ndi kuyenda panyanja. Chingwe cha PET (chingwe cha poliyesitala) ndi chingwe cha poliyesitala zonse zimagwiritsidwa ntchito poteteza katundu, koma zimagwira ntchito mosiyana kwambiri. Chingwe cha poliyesitala chimatambasulidwa pansi pa katundu, sichimangika pamene katundu ukukhazikika, ndipo chimaphuka msanga ndi zitsulo zakuthwa.

Chingwe cha PET (chingwe cha poliyesitala) chimapezeka mu makulidwe kuyambira 0.4mm mpaka 1.25mm, ndipo mtundu uliwonse umagwirizana ndi zofunikira zinazake komanso mitundu ya zida. Zingwe zopyapyala (0.4-0.55mm) zimanyamula katundu wopepuka komanso kulongedza wamba, pomwe zosankha zokhuthala (0.8-1.25mm) zimagwira zitsulo zachitsulo, mababu a thonje, ndi ntchito zamafakitale zofunika kwambiri.

Miyezo yapakati ndi zina mwazomwe zimanyalanyazidwa kwambiri pamene ogula amasankha chingwe cha PET (chingwe cha poliyesitala) kuti azimangirira zokha. Chingwe chomwe chimakwaniritsa zofunikira zonse zamakina - m'lifupi mwake, makulidwe ake, ndi mphamvu yosweka - chidzayambitsabe mavuto odyetsa ngati kukula kwake sikufanana ndi choperekera mutu. M'kati mwake, m'lifupi mwake, m'lifupi mwake, ndi mpukutu wakunja kwake zonse ziyenera kugwirizana ndi makina opikira ndi kupumula. Bukuli likufotokoza kukula kwa zingwe za PET, momwe zimakhudzira magwiridwe antchito amutu, komanso momwe mungatsimikizire kuti zimagwirizana musanagule.

Kusankha pakati pa chingwe cha PET (chingwe cha poliyesitala) ndi chingwe chachitsulo ndi chimodzi mwazosankha zofunika kwambiri pakuyika mafakitale. Chingwe cha PET chimapereka ndalama zokwana 50% paphazi lililonse, chimachotsa ziwopsezo zovulala kuchokera m'mbali zakuthwa ndi snap-back, ndipo chimapereka kusungika kwamphamvu kwambiri pamene katundu amakhazikika paulendo. Zomangira zitsulo zimapereka kukhwima kwakukulu kwa katundu wochuluka koma zimakhala ndi ndalama zobisika kuphatikizapo zofunikira zogwirira ntchito, kuopsa kwa dzimbiri, ndi kuvala kwa zipangizo. Malinga ndi deta yamakampani, lamba la PET limapereka kuwirikiza kanayi mizere yofananira pa tani iliyonse poyerekeza ndi chitsulo, kusintha mtengo wa equation.
