1. Zinthu zachikwama cha tani ya chidebe
Zida zomwe zimagwiritsidwa ntchito makamaka zimaphatikizapo polypropylene (PP) ndi polyethylene (PE), zomwe ndi zosankha zoyamba kupanga mabale ochuluka chifukwa cha makina awo abwino kwambiri komanso kukana kwa dzimbiri. Kuphatikiza apo, pali zinthu zina monga poliyesitala ndi nayiloni zomwe zimagwiritsidwanso ntchito pazinthu zinazake.
Polypropylene (PP)
Polypropylene (PP) imakhala ndi mphamvu zolimba kwambiri komanso kukana abrasion, zomwe zimathandizira kuti chikwama cha tani ya chidebecho chizikhala chokhazikika komanso kuti chisakhale chosavuta kuthyoka ponyamula ndi kunyamula katundu wolemetsa. Kusagwira kwake kwamankhwala kumapangitsa PP kugonjetsedwa ndi ma acid ambiri, alkalis ndi zosungunulira za organic, zomwe zimapangitsa kuti zikhale zoyenera kuyika zinthu zama mankhwala. Kuphatikiza apo, kuchepa kwa PP kumapangitsa kuti ikhale yopepuka, yosavuta kuigwira komanso yosungira. PP ilinso ndi magwiridwe antchito abwino, ndipo imatha kusinthidwa kukhala zotengera zamitundu yosiyanasiyana ndi mawonekedwe kudzera pakuluka, zokutira ndi kusoka, kuti zikwaniritse zosowa za makasitomala osiyanasiyana. Kukana kwake kutentha ndi kukana kukalamba kumapangitsanso FIBC yopangidwa ndi PP kukhala yoyenera kugwiritsidwa ntchito kwa nthawi yayitali m'malo osiyanasiyana anyengo. PP ndi yogwirizana ndi chilengedwe komanso yobwezeretsanso, komabe ndikofunikira kulabadira kuchepetsa kukhudzidwa kwa chilengedwe pakupanga ndi kubwezeretsanso.
Polyethylene (PE)
Ubwino umodzi waukulu wa polyethylene (PE) ndi kusinthasintha kwake komanso kukana kwamphamvu, komwe kumalola mabale ambiri kuti azitha kuyamwa mphamvu panthawi yonyamula ndi kunyamula, kuchepetsa chiopsezo chosweka. Kusakwanira kwa mankhwala kumapangitsa PE kugonjetsedwa ndi ma acid ambiri, zoyambira, ndi mchere, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito posungira ndi kunyamula mankhwala. Kutsika kwa kutentha kwa PE ndikwabwinoko kuposa kwa PP, ndipo kumatha kukhalabe olimba m'malo ozizira ndipo sikumakonda kukhala brittleness. Kachulukidwe kakang'ono ka PE kumapangitsa kuti mabale ochuluka omwe amapangidwa kuti akhale opepuka komanso osavuta kunyamula ndikugwiritsa ntchito. PE imakhalanso ndi kukana kwabwino kwa ukalamba, ndipo powonjezera ma antioxidants ndi UV stabilizers, imatha kukulitsa moyo wautumiki wamatumba a toni.
2 Njira yopangira phukusi lambiri
Njira yoluka
Njira yoluka ndi imodzi mwazinthu zofunika kwambiri pakupangamatumba a toni, yomwe imagwira ntchito yodalirika mu mphamvu zake ndi kulimba kwake, pogwiritsa ntchito polypropylene (PP) kapena polyethylene (PE) monga chinthu chachikulu, chomwe chimapangidwa kukhala mawaya athyathyathya kudzera mu ndondomeko yojambula mawaya, ndiyeno mawaya ophwanyikawa amapangidwa mu nsalu pogwiritsa ntchito nsalu yozungulira. The kuluka kachulukidwe ndi kuluka njira mwachindunji zimakhudza thupi katundu wa chidebe tani thumba. Kuluka kolimba kwambiri kumatha kupititsa patsogolo kulimba kwamphamvu komanso kuvala kukana kwa mabale ochulukirapo, koma nthawi yomweyo kumawonjezera kuchuluka kwazinthu zomwe zimagwiritsidwa ntchito komanso ndalama zopangira. Kuti akwaniritse ntchito yabwino, kachulukidwe woluka wololera ndi njira zoluka, monga zokhotakhota zosawoneka bwino komanso zoluka za satin, nthawi zambiri zimagwiritsidwa ntchito kuti zitheke pakati pa mphamvu ndi mtengo. Pakuluka, m'pofunikanso kulabadira chifanane ndi kukhazikika kwa ndondomeko kuluka kupewa mkangano kuluka ndi nsalu zolakwika, amene kuchepetsa kubala mphamvu ndi moyo utumiki wa chidebe tani thumba.
Njira yokutira
Pogwiritsa ntchito njira yophimba, polypropylene (PP) kapena polyethylene (PE) zakuthupi zimakutidwa pamwamba pa nsalu yotchinga kupyolera muzitsulo zopangira zowonjezera kuti apange filimu yofanana, yomwe ingateteze bwino kulowa kwa chinyezi ndi mankhwala, kuti ateteze katundu mkati. Pakuphimba, makulidwe ndi kufanana kwa zokutira ndizofunika kwambiri zolamulira. Zovala zokulirapo zimatha kusintha kukana kwamadzi ndi mankhwala, koma kuonjezera kuchuluka ndi mtengo wazinthu; Chophimba chocheperako sichingapereke chitetezo chokwanira. Kuti mukwaniritse zotsatira zabwino, makulidwe a zokutira ndi zofanana ziyenera kuyendetsedwa mwamphamvu panthawi yopanga. Kugwiritsa ntchito zida zapamwamba extrusion ndi dongosolo kulamulira basi, mkulu-mwatsatanetsatane ❖ kuyanika ndondomeko akhoza anazindikira.
