Pa kutumiza mphamvu kwa makina osinthasintha, ntchito yosathandiza yomwe imagwiritsidwa ntchito potumiza mphamvu, mphamvu imasungidwa bwino. Pa kutumiza mphamvu kwa lamba wamba, kulemera kwa thupi la lamba, malo okulungidwa ndi mulifupi wa gudumu ndi mphamvu yowonjezera yokhazikika zimatsimikiza momwe thupi la lamba limagwiritsidwira ntchito. Chifukwa chake, kusankha ndi kukonza lamba wotumizira mphamvu mu chipangizocho ndi chinthu chofunikira kwambiri kuti musunge mphamvu, ndipo lamba wotumizira mphamvu wokhala ndi kutalika kokhazikika, thupi la lamba wofatsa komanso kukangana pang'ono pamwamba ndiye chisankho chabwino kwambiri kwa makasitomala. Lamba woyendetsa wa Annilte wa polyester amathetsa mavuto omwe ali pamwambapa bwino.
1. Polyester yokhala ndi mawonekedwe osungira mphamvu
a) Mphamvu yolimba komanso kulimba mtima kokhazikika.
Kawirikawiri, poyerekeza ndi gawo lapansi, mphamvu yotambasula yokhazikika ya 1% ya lamba wa polyester imakhala yokwera ndi 30% mpaka 50%, zomwe zikutanthauza kuti lamba siliyenera kusintha mphamvu yotambasula mobwerezabwereza mutasintha mphamvu yotambasula. Kuphatikiza apo, imagwira ntchito bwino, mphamvu yolimba komanso yosavuta kutaya liwiro, kotero kuti katundu wonyamula katundu umachepetsedwa, motero kusunga magetsi.
b) Zingwezo ndi zopepuka kulemera
Lamba la polyester lolimba kwambiri ndi kapangidwe kake kapadera ka nsalu ya polyester yotsika kwambiri, pomwe mphamvu yotumizira mphamvuyo imafanana, mutha kusankha lamba woonda kwambiri, kuti muchepetse nthawi ya inertia ndi mphamvu ya centrifugal ya lamba lathyathyathya, kuti mphamvu zake zichepetsedwe ndipo mphamvu zamagetsi zisungidwe.
c) Kusinthasintha kwabwino
Popeza thupi la lamba wa polyester ndi lofewa, thupi la lamba ndi gudumu la lamba zimakulungidwa bwino, kupsinjika kopindika kumachepa, mphamvu yotumizira imawonjezeka ndipo mphamvu yogwiritsira ntchito mphamvu imasungidwa pang'ono.
d) Cholumikiziracho ndi chachangu komanso choteteza chilengedwe
Cholumikiziracho chimagwiritsa ntchito cholumikizira cha dzino chosungunuka cha thupi la elastomer ya thermoplastic, palibe guluu wogwiritsidwa ntchito, ndipo ntchitoyo siili yocheperako, kotero nthawi yoyika imasungidwa ndipo kuipitsa chilengedwe kumachepetsedwa.
2. Mphamvu yopulumutsa mphamvu
Kuyesa koyerekeza kwa munda kukuwonetsa kuti kuchuluka kwa mphamvu yosungira mphamvu ya polyester strip ndi kokwera kuposa 10% kuposa kwa chip baseband yakunyumba ndi yakunja.
Mphamvu yopulumutsa mphamvu ya lamba wa polyester ndi yofunika kwambiri, pa makina ophikira ulusi, mphamvu yopulumutsa mphamvu imatha kufika 20%, pa makina opindika kawiri a ulusi waufupi, mphamvu yopulumutsa mphamvu ndi yoposa 15%, pa makina opindika ka 310, mphamvu yopulumutsa mphamvu ndi 10%. Chifukwa chake, lamba wa polyester wokhala ndi magwiridwe antchito abwino kwambiri opulumutsa mphamvu, wakhala akugwiritsidwa ntchito kwambiri ngati lamba wa chinjoka ndi lamba wamagetsi wa zida zatsopano zothamanga kwambiri monga makina ophimba ulusi, makina opota otalika kwambiri, makina opota ozungulira ndi makina opota awiri.
3. Kuyerekeza magwiridwe antchito a kapangidwe kake
Lamba wa polyester amapangidwa ndi rabara yapadera ya carboxyl nitrile butadiene yopangidwa ngati chinthu chachikulu choyendetsera ndi kukangana, ndipo magwiridwe antchito ake ndi ofanana ndi a substrate.
Chipepala cha thermoplastic polymer elastomer chimagwiritsidwa ntchito ngati gawo losinthira la composite. Pambuyo pouma, tinthu ta thermoplastic polymer timasungunuka ndikutulutsidwa ndi extruder kuti tipange pepalalo ndi makulidwe ofanana ndi m'lifupi mwa 1200mm. Ndipo malinga ndi makulidwe osiyanasiyana a lamba, makulidwe osiyanasiyana a zinthu za pepala ndi 0.3 ~ 1.2mm. Zipangizozo zili ndi mawonekedwe a kusinthasintha kwabwino, kukana mafuta, kukana kutentha, kukana kutopa, kusinthasintha, mphamvu yochepa komanso kulemera kopepuka, ndipo zimakhala ndi mphamvu zabwino zomangira ndi gawo lamphamvu komanso rabala.
