Ubwino wa zingwe za PET ndi chiyani?(II)

Chachinayi, magwiridwe antchito achitetezo.
Chingwe cha pet chimakhala ndi chiwongolero chotalikirapo komanso chiwongolero cha 10% -14%, pamene lamba wonyamula chitsulo kapena waya wachitsulo amangokhala ndi elongation ndi mlingo wa 3-5%.Mwa kuyankhula kwina, lamba la ziweto lidzamangidwa mwamphamvu kwambiri ndipo sikophweka kumasuka.Kuphatikiza apo, katundu womangidwa m'mitolo akadali ndi buffer elongation rate ya 10-14% ikakhudzidwa ndi mphamvu yakunja yakunja, zomwe sizosavuta kusweka lamba mwachindunji, kuwonetsetsa kuti katunduyo ndi wotetezeka komanso wosamasuka.
Pa nthawi yomweyi, lamba wa pulasitiki-zitsulo zonyamula katundu zimagwirizanitsa makhalidwe a pulasitiki, ndipo palibe malire akuthwa a lamba wachitsulo, omwe sangawononge chinthu chophatikizidwa, ndipo sichidzavulaza wogwiritsa ntchito panthawi yonyamula. ndi kumasula katundu.

Panthawi imodzimodziyo, lamba wa pet amagwirizanitsa makhalidwe a pulasitiki, opanda malire akuthwa a lamba wachitsulo.Sichidzawononga chinthu chopakidwa, ndipo sichidzavulaza wogwiritsa ntchito panthawi yonyamula ndi kumasula.

Chachisanu, kulongedza bwino.
Lamba wa ziweto ndi wopepuka komanso wosavuta kunyamula;mukamagwiritsa ntchito lamba wa pulasitiki-zitsulo zonyamula katundu, zimatha kuphatikizidwa ndi makina onyamula pamanja, makina osindikizira a pneumatic kapena makina opangira magetsi, osadula lamba pasadakhale, ntchitoyo ndi yosavuta, komanso kunyamula bwino ndipamwamba.

Kuti apange zomangira zabwino zimafunikira makina apamwamba kwambiri.Laizhou Kaihui Machinery Co., Ltd ndi wopanga mizere yotulutsa pulasitiki yopitilira zaka 30.Iwo ndi odziwa kupangamizere ya zingwe za pet, mizere ya pet monofilament komanso mizere yobwezeretsanso yomwe imapanga mabotolo a ziweto kukhala flakes.
