Kuwunika kwa PVC Stretch Fabric Forming Process

Nsalu zotambasula za PVC, zotanuka kwambiri komanso zolimba, zimagwiritsidwa ntchito kwambiri pazinthu zakunja, mahema, nsalu zotsatsa, ndi zida zodzitetezera kuchipatala. Kapangidwe kake kumakhudza kwambiri momwe zinthu zimagwirira ntchito komanso moyo wake wautumiki, zomwe zimapangitsa kuti zikhale kofunika kudziwa bwino kayendedwe kake.

Kapangidwe ka nsalu ya PVC ili ndi masitepe anayi ofunika kwambiri: kusakaniza zinthu, kutulutsa kalendala, kutambasula ndi kuyang'ana, ndi positi-kukonza. Choyamba, utomoni wa polyvinyl chloride (PVC) umasakanizidwa ndi zowonjezera monga plasticizer, stabilizers, ndi mafuta odzola moyenerera ndikugawanitsidwa molingana ndi-zosakaniza zothamanga kwambiri kuti apange phala lokhala ndi kukhuthala kwapadera. Kusankhidwa kwa zowonjezera panthawiyi kumakhudza mwachindunji kusinthasintha kwa zinthu, kukana kwa nyengo, ndi kukana kwa UV.

Zosakanizazo zimalowa mu extruder, momwe zimasungunuka kutentha kwambiri (pafupifupi 160-180 digiri) ndikutuluka kudzera mu T-die kukhala pepala. Kenako pepalalo limapangidwa ndi ma roller kuti liwongolere makulidwe ndi kusalala kwa pamwamba. Kutentha kwa calendering kuyenera kuyendetsedwa bwino kuti zisawonongeke chifukwa cha kutenthedwa kapena kupsinjika kwamkati komwe kumachitika chifukwa cha kuzizira.

Kutambasula ndi kuwongolera ndi njira yoyambira yomwe imapereka nsalu yotambasula ya PVC yokhala ndi kukhazikika kwake. Tsambali limatenthedwa kale (nthawi zambiri 80-madigiri 120 ) lisanatambasulidwe mwauniaxially kapena biaxially mu makina otambasula aatali kapena odutsa. Chiŵerengero chotambasula nthawi zambiri chimakhala nthawi 2-5, kugwirizanitsa maunyolo a maselo kuti apite ku mphamvu, kumapangitsa kuti zinthuzo zikhale zotalika komanso zolimba. Zogulitsa zina zapamwamba zimagwiritsa ntchito ukadaulo wotsatizana kuti ziwonjezeke bwino pamakina.

Pomaliza, nsalu yotambasulidwa imakumana ndi kutentha komanso kuziziritsa. Kutentha kumaphatikizapo kutentha kwakukulu (pafupifupi 100-130 digiri) kuti akhazikitse dongosolo la mamolekyu ndi kuthetsa kupsinjika kotsalira. Kuziziritsa kumachitika ndi mpweya kapena madzi kuonetsetsa bata laling'ono. Zogulitsa zina zimafunikiranso chithandizo chapamwamba, monga zokutira zosagwira ndi UV kapena zoletsa moto kuti zithandizire kugwira ntchito.

The akamaumba kwa PVC Tambasula nsalu amafuna kulamulira okhwima kutentha, liwiro, ndi mavuto magawo. Kupatuka mu sitepe iliyonse kungapangitse kuti zinthu zisamayende bwino. Kupita patsogolo kwaukadaulo, monga kuyambitsa kuwunika kwapaintaneti ndi kuwongolera makina, kukuyendetsa njira zamakono kuti zitheke bwino komanso kuti zizikhala bwino ndi chilengedwe, zomwe zimapereka mayankho apamwamba kwambiri pamagwiritsidwe ntchito otsika.
