Chikwama choyenda ndi chida chopangidwa ndi katundu wopangidwa ndi katundu. Tsamba lililonse ndi gulu lililonse limanyamula gawo la malingaliro a thumba, makamaka ku zipper. Chikwangwani chodzaza ndi 28l chikukwera chimakhala makilogalamu 3-7 makilogalamu pa ziphuphu zazikulu za chipinda chachikulu, kutengera kuchuluka ndi kupindika kwa nsalu. Mapaketi akuluakulu okwanira (40-60l) amatha kufikira 10-14 makilogalamu a zipper kupsinjika pansi pa gulu lamphamvu monga kudumpha, kutsika, kapena kumangirira.
Chifukwa matumba ambiri oyenda maulendo amagwiritsa ntchito 210D, 420d, kapena 600d nylon ndi mphamvu zosiyanasiyana zakuso, zipper ziyenera kufanana ndi makina a nsaluyo. Ngati zipper ndi wofooka kuposa kapangidwe kazizungulira, paketiyi idzalephera pamalo ake ofooka - nthawi zambiri mano.
Matumba okwera kwambiri okwera kwambiri chifukwa chake zipper osati zowonjezera, koma monga zida zonyamula katundu.
Chifukwa chiyani zipper zimalephera mu malo ankhanza kunja
Gawo laukadaulo lomwe limafotokoza kusiyana pakati pa SBS ndi maficper a zbk zipper, kuyika mbiri, ndikupanga matepi omwe amagwiritsidwa ntchito m'matumba okwera kwambiri.
Sayansi Yakuthupi Kutengera Zippers
Zida zopangira mano
Mano a zipper amazindikira kuti thumba lokongola limakhala ndi umphumphu pansi. Zida zodziwika bwino ndizophatikiza:
• NYNA 6: Malo osungunuka 215 ° C, mphamvu yayikulu ~ 75 MPA • NYNA 66: malo osungunuka 255 ° C, mphamvu ya Tunsile ~ 82 MPA • Pom: Kulimba kwambiri kwamphamvu kwambiri, koyenera kwa ma fumbi
Nylon 66 imakhala yofunika kwambiri m'matumba okwera kwambiri chifukwa kuuma kwake kumakhala kokhazikika kumatentha kwambiri - kuyambira -5 ° C kwa + 45 ° C.
Nsalu za tepi
Pipper tepi iyenera kufanana ndi nsalu ya thupi:
• 210d nylon: Zabwino kwa matumba owoneka bwino • 420d nylon: mphamvu moyenera • 600D oxford: kukana kwamphamvu kwa abrasion kwa ma utoto
Tepi ya 420d ili ndi pafupifupi 40-60% kuvutitsidwa kwambiri kuposa 210D, ndikupangitsa kuti zisankhidwe bwino kwa maxpepi ndi 28l.
Malingaliro a Mchenje a nayiloni ndi kapangidwe ka polymer coul yomwe imapanga sayansi ya zipsera za zipsera zamagetsi zomwe zimagwiritsidwa ntchito m'matumba amakono oyendayenda.
Chifukwa chiyani matumba okwera kwambiri amasankha sbs / ykk
Zifukwa zoyambira
Akatswiri opanga ziphuphu opanga zipper a Zipper Modems pansi pa zolimbitsa:
Sbs ndi Ykk nthawi zonse amakhala ndi zipper zamiyendo chifukwa cha kulumikizana kwa dzino, olimba mtima, komanso kukhazikika kwa nthawi yayitali. Chikwama chochepa kwambiri chimayenera kukhalapo ndi makilogalamu 20 mpaka kusunthira nthawi, chomwe chimafuna dongosolo lokhazikika.
Makonda a Surproof & Fumbi
Zipata zam'madzi zopanda madzi ndizofunikira kwa alpine kapena madera amvula. Zipper za TPU-yotayidwa zimachepetsa kulowa kwamadzi ndi 80-90% poyerekeza ndi zipper zofananira. Sbs Zippers Zippers zimachita bwino mumvula yayikulu, pomwe zolemba za ykk zimapereka chitetezo champhamvu kwambiri cha ma hydrophobic.
Zochita zamakampani zipper za zippars mu 2025-2030
Makampani oyenda pamatumbo akusunthira ku:
• Chikwangwani chonyezimiraMapangidwe (<900G) akufuna zippers zotsika • Zipangizo zobwezerezedwanso zipper zogwirizana ndi malingaliro okhazikika • Kukonzanso nyengo yozizira kwa misika yozizira • Kuchulukitsidwa kukhazikitsidwa kwa syperproof micper
Podzafika 2030, zippers polymer zobwezerezedwanso zikuwonetsedwa kuti zikuyimira 40% ya zopangidwa kunja kwa zida za EU.
Momwe mungasankhire zipper kumanja kwa thumba loyenda
Maakaunti a zipper ku ZIPPET mpaka 40-50% ya zolephera zam'mawa. Dongosolo lamphamvu lazikulu limachulukitsa kwambiri kudalirika kwa nthawi yayitali komanso chitetezo pakuyenda.

Lipoti la msika wakunja, mabizinesi akunja, 2024.
Kuzindikira magwiridwe antchito akunja, mtolankhani wa sayansi ya zakuthupi, Dr. L. Thompson.
Kuyika makina kuyesa kwa zigawo zam'manja, malo ophunzitsira apadziko lonse lapansi.
Kuzizira kwa nyengo mumitundu ya Nylon, kuwunika kwamaudindo.
