Nsalu yowumitsira yolukidwa mwala ndi nsalu yowumitsira yozungulira ndi mitundu iwiri yodziwika bwino ya nsalu zowumitsira za polyester zomwe zimagwiritsidwa ntchito powumitsira mapepala. Kusiyana kwakukulu pakati pawo kumachokera ku njira zolukira (zolukitsira zopanda zingwe zokhala ndi warp yolumikizidwa ndi weft / monofilament spiral interlocking). Ubwino ndi kuipa kwawo ndi kogwirizana kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito mitundu yosiyanasiyana yopanga mapepala.

Kuyerekeza kolondola kwaperekedwa pansipa potengera zabwino zazikulu, zofooka zoonekeratu, ndi zochitika zomwe zingagwiritsidwe ntchito, pamodzi ndi maumboni ofunikira osankhidwa:

I. Nsalu Youmitsira Yolukidwa Mwathyathyathya

Ubwino Waukulu

• Kukhazikika kwamphamvu kwa kapangidwe kake: Kulumikizana pafupipafupi kwa ulusi wa wopindika ndi weft kumapereka kulimba kwabwino komanso kusintha pang'ono. Nsaluyo siitha kupotoka kapena kukwinya ikagwiritsidwa ntchito, ndipo imakhala yovuta kwambiri poletsa kupsinjika, yoyenera kuumitsa mwachizolowezi pamakina a mapepala apakati komanso otsika.
• Malo okwera kwambiri komanso mpweya wofanana: Kapangidwe kolimba kolumikizana kameneka kamatsimikizira kuti palibe kusiyana koonekera bwino kwa mipata pamwamba pa nsalu, zomwe zimapangitsa kuti pepalalo litenthedwe bwino komanso lichotse madzi mofanana. Limachepetsa bwino zolakwika za pepala monga zolukidwa, mawanga, ndi makulidwe osafanana, zomwe zingagwiritsidwe ntchito ndi zofunikira zoyambira kuti pamwamba pake pawoneke bwino.
• Kuchita bwino kwa mtengo: Ukadaulo woluka wokhwima komanso kugwiritsa ntchito zinthu zopangira zambiri kumapangitsa kuti mtengo wogulira ukhale wotsika ndi 15%–30% kuposa nsalu yowumitsira yozungulira yomwe ili ndi mfundo zomwezo. Zigawo ndi kukonza zimapezeka mosavuta pamsika, zomwe zimapangitsa kuti ndalama zogwirira ntchito ndi kukonza zizikhala zochepa pambuyo pake.
• Kukana kuvala bwino: Kumangirira kolimba pamalo olumikizirana kumapangitsa nsaluyo kukhala yolimba kuposa nsalu yowumitsira yozungulira yokhala ndi mulifupi wofanana wa ulusi, zomwe zimapangitsa kuti ikhale yogwira ntchito nthawi yayitali m'malo owumitsira wamba.
• Kusinthasintha kwakukulu: Imapezeka m'njira zosiyanasiyana kuphatikizapo mtundu umodzi ndi theka wa wosanjikiza, wachiwiri, ndi wathyathyathya wa ulusi, womwe umaphimba pafupifupi mitundu yonse ya mapepala monga pepala lopyapyala (pepala lachikhalidwe), pepala lokhuthala (pepala lopaka), ndi bolodi la mapepala. Ndi nsalu yowumitsira "yodziwika bwino" mumakampani opanga mapepala.

Zofooka Zoonekeratu

• Kusinthasintha kosakwanira komanso kusasalala bwino kwa mafupa: Kapangidwe kolimba kamapangitsa kuti zikhale zopindika mofooka. Mapulagi olumikizira kapena ma sliced ​​​​joints ali ndi mipata yolumikizirana, yomwe imayambitsa kugwedezeka ndi phokoso pa liwiro lalikulu, ndipo imatha kukanda pepala kapena zida. Sikoyenera makina apepala othamanga kwambiri (> 800 m/min).
• Kusinthasintha kochepa kwa mpweya wolowera: Kapangidwe kolukidwa kosasinthika sikungasinthe kulowera kwa mpweya mwa kusintha mtunda ngati nsalu yowumitsira yozungulira, zomwe zimapangitsa kuti isasinthe mosavuta njira zapadera zowumitsira (monga, kuchotsa madzi mwachangu pamapepala okhala ndi chinyezi chambiri).
• Kuwonongeka kwa m'deralo kumafalikira: Ulusi wopindika ndi weft umagwirizana. Ngati ulusi wosweka sunakonzedwe pa nthawi yake, ukhoza kuyambitsa kuwonongeka kwa ulusi woyandikana nawo, zomwe zimachepetsa kukhazikika konse pambuyo pokonza.

II. Nsalu Yowumitsira Yozungulira

Ubwino Waukulu

• Kusinthasintha kwabwino komanso kugwira ntchito bwino: Kapangidwe kopanda weft kopangidwa ndi monofilament spirals yolumikizana bwino kamapereka magwiridwe antchito abwino opindika. Cholumikiziracho chimagwiritsa ntchito kulumikizana kwa spiral loop, komwe kuli kopanda mipata komanso kopanda masitepe. Chimakhala ndi kugwedezeka kochepa komanso phokoso lothamanga kwambiri, koyenera makina apepala othamanga kwambiri (> 800 m/min) ndi zida zowumitsira zopindika.
• Mpweya wosinthika mosavuta: Mwa kusintha kukula ndi mtunda wa ulusi wozungulira, kulowa kwa mpweya kumatha kuyendetsedwa bwino pamitundu yosiyanasiyana, kusintha malinga ndi zofunikira zapadera monga kuchotsa madzi mwachangu pamapepala okhala ndi chinyezi chambiri komanso kuumitsa pepala lopyapyala kutentha kochepa.
• Kukonza kosavuta kwa kuwonongeka kwapafupiPopanda zopinga zopingasa zopingasa ndi zopingasa, ulusi umodzi wosweka wozungulira ukhoza kusinthidwa pang'ono popanda kusintha nsalu yonse. Kukonza ndikosavuta ndipo sikukhudza kukhazikika kwa ntchito yonse.
• Chithunzi cha pepala lopepuka: Palibe malo olumikizirana oonekera bwino pamwamba pa nsalu omwe amapereka kukhudzana kofewa ndi pepalalo, zomwe zimachepetsa "ma mesh marks". Yoyenera kugwiritsidwa ntchito pofunikira kusalala kwambiri pamwamba (monga pepala lapamwamba kwambiri, pepala lophimbidwa).

Zofooka Zoonekeratu

• Kulimba kwa kapangidwe kofooka komanso kusinthasintha kosavuta: Kusowa kwa choletsa cha weft kumabweretsa kusintha kwakukulu kwa nsalu. Zimafuna kulondola kwambiri kwa makina owongolera kupsinjika ndi zida zowongolera panthawi yogwira ntchito. Kusakwanira kwa zida zolondola kumayambitsa kupotoka ndi makwinya.
• Kugula zinthu zambiri komanso ndalama zogwirira ntchito: Njira yovuta yolukira nsalu komanso kufunika kwa zinthu zambiri kumapangitsa kuti mtengo wogulira ukhale wokwera ndi 30% kuposa nsalu yowumitsira yolukidwa bwino yomwe ili ndi mfundo zomwezo. Ilinso ndi zofunikira kwambiri pa malo ogwirira ntchito (monga ukhondo, kukhazikika kwa kupsinjika), zomwe zimapangitsa kuti ndalama zokonzera zinthu zikhale zapamwamba kwambiri tsiku lililonse.
• Kukana kuvala kofooka: Palibe malo othandizira olumikizana omwe amachititsa kuti pakhale kupsinjika kwakukulu pakati pa monofilaments, dryer, ndi mapepala. Kuthamanga kwapafupi kumakhala kofulumira kuposa nsalu yolukidwa bwino itatha kugwiritsidwa ntchito kwa nthawi yayitali. Yoyenera malo oyera owuma opanda zinyalala.
• Kusinthasintha kochepa ku magiredi a pepala: Kulimba pang'ono kumapangitsa kuti ikhale yosayenera kuumitsa mapepala olemera (monga pepala lokhala ndi ma corrugated paper, linerboard), chifukwa kulemera kwa pepala kungawononge nsalu ndikusokoneza kufanana kwa kuumitsa.

III. Chilolezo Chosankha Pakati (Kufananiza Mwachangu kwa Zochitika)

IV. Mapeto

Nsalu yowumitsira yolukidwa bwino ndi"Mtundu wapadziko lonse wotsika mtengo", yokongola kwambiri pa kapangidwe kokhazikika, yotsika mtengo, komanso yosinthasintha kwambiri. Ndi yoyenera pamizere yambiri yopanga mapepala yapakatikati ndi yotsika kwambiri yomwe imapanga mapepala achikhalidwe.

Nsalu yowumitsira yozungulira ndi"Mtundu wapamwamba kwambiri wopangidwira njira zapadera", yogwira ntchito bwino kwambiri, yosalala, komanso yolola mpweya kulowetsedwa. Ndi yoyenera kupanga mwachangu mapepala opyapyala apamwamba komanso mapepala apadera okhala ndi njira zapadera zowumitsira, koma ili ndi malire apamwamba pakugwiritsa ntchito zida molondola, mtengo, ndi kukonza.

Mu kusankha kothandiza:

• Konzani nsalu yowumitsira yopangidwa ndi nsalu yathyathyathya ngati liwiro la makina a pepala ndi <800 m/min ndipo makamaka imapanga pepala lokhuthala kapena bolodi la mapepala.
• Ganizirani nsalu yowumitsira yozungulira ngati liwiro lake ndi > 800 m/min, ndikupanga pepala lopyapyala lapamwamba kapena pepala lapadera lokhala ndi zida zolondola.
