Kwa kufala kwamakina osinthika, ntchito yocheperako yomwe imagwiritsidwa ntchito popereka mphamvu, ndi yabwino kupulumutsa mphamvu. Pakuti njira kufala mphamvu ya wamba lamba lamba, kulemera kwa lamba thupi, dera atakulungidwa gudumu m'mimba mwake ndi yokhazikika kuwonjezera mphamvu kudziwa mphamvu ya lamba thupi pamene ntchito. Choncho, kusankha ndi kasinthidwe lamba kufala mu zipangizo ndi chinthu chofunika kwambiri kukhathamiritsa kupulumutsa mphamvu, ndi lamba kufala ndi wapamwamba fixed elongation, wofatsa lamba thupi ndi zolimbitsa pamwamba mikangano ndi kusankha bwino kwa customers.Annilte a polyester lamba pagalimoto amathetsa mavuto pamwamba bwino.
1. Polyester yokhala ndi mphamvu zopulumutsa mphamvu
a) Kulimba kwamphamvu kwambiri komanso kukhazikika kokhazikika.
Kawirikawiri, poyerekeza ndi gawo lapansi, mphamvu ya 1% yokhazikika ya lamba wa polyester ndi 30% mpaka 50% pamwamba, zomwe zikutanthauza kuti lamba sayenera kusintha kugwedezeka mobwerezabwereza mutatha kusintha mphamvu. Kuonjezera apo, ntchito yake yosalala, kuthamanga kwapakati komanso kosavuta kutaya liwiro, kotero kuti katundu wonyamula ndi wochepa, motero amapulumutsa magetsi.
b) Zingwezo ndi zopepuka kulemera
The amphamvu wosanjikiza lamba poliyesitala ndi dongosolo lapadera la mkulu-mphamvu otsika-elongation poliyesitala nsalu, pamene mphamvu yomweyo kufala, mukhoza kusankha woonda lamba lamba, kuti kuchepetsa mphindi ya inertia ndi centrifugal mphamvu ya lamba lathyathyathya. , kotero kuti mphamvu zake zogwiritsira ntchito mphamvu zichepetse komanso kugwiritsa ntchito magetsi kupulumutsidwa.
c) Kusinthasintha kwabwino
Chifukwa thupi la lamba la polyester ndi lofewa, thupi lamba ndi gudumu la lamba zimakulungidwa bwino, kupsinjika komwe kumapindika kumachepetsedwa, kupititsa patsogolo kumayenda bwino komanso kugwiritsa ntchito mphamvu kumapulumutsidwa.
d) Cholumikizira ndichofulumira komanso chokonda zachilengedwe
Cholumikiziracho chimatengera kulumikiza kwa dzino lotentha la thupi la thermoplastic elastomer, palibe zomatira zomwe zimagwiritsidwa ntchito, ndipo ntchitoyo siili malire, motero nthawi yoyika imasungidwa ndikuwononga chilengedwe.
2. Mphamvu yopulumutsa mphamvu
Mayeso oyerekeza kumunda akuwonetsa kuti chiwopsezo chopulumutsa mphamvu chamzere wa poliyesitala ndi wapamwamba kuposa 10% kuposa wa chip baseband wakunyumba ndi akunja.
Mphamvu yopulumutsa mphamvu ya lamba wa poliyesitala ndiyofunikira kwambiri, pamakina opaka ulusi, mphamvu yopulumutsa mphamvu imatha kufika 20%, pamakina afupiafupi opindika awiri, kupulumutsa mphamvu kumaposa 15%, kwa makina opotoka nthawi 310. , mphamvu yopulumutsa mphamvu ndi 10%. Chifukwa chake, lamba wa poliyesitala wokhala ndi mphamvu yabwino yopulumutsa mphamvu, wakhala akugwiritsidwa ntchito kwambiri ngati lamba wa chinjoka ndi lamba wamagetsi a zida zatsopano zothamanga kwambiri monga makina otchingira ulusi, makina opota atali kwambiri, makina opota ozungulira ndi makina opindika awiri.
3. Kufananiza kachitidwe kamangidwe
Lamba wa poliyesitala amapangidwa ndi mphira wapadera wa carboxyl nitrile butadiene ngati chinthu chachikulu pakuyendetsa ndi kusanjikizana, ndipo magwiridwe ake ndi ofanana ndi gawo lapansi.
Thermoplastic polima elastomer pepala ntchito ngati gulu kusintha wosanjikiza. Pambuyo kuyanika, thermoplastic polima particles ndi kusungunuka ndi extruder ndi extruder kupanga pepala ndi makulidwe yunifolomu ndi m'lifupi 1200mm. Ndipo malinga ndi makulidwe osiyana a lamba akamaumba thupi 0,3 ~ 1.2mm makulidwe osiyana a mankhwala pepala. Nkhaniyi ili ndi makhalidwe abwino kwambiri, kukana mafuta, kukana kutentha, kukana kutopa, kusinthasintha, mphamvu yokoka yaing'ono ndi kulemera kwake, ndipo imakhala ndi zinthu zabwino zomangirira ndi wosanjikiza wamphamvu ndi mphira.
