Mbiri yachitukuko cha chikopa chopanga chopanga

Kumayambiriro kwa zaka za m'ma 1900, nsalu ya nitrocellulose lacquer yopangidwa ndi nsalu yokutira ndi nitrocellulose sol inali mpainiya wa zikopa zopangira.m'zaka za m'ma 1930, kupanga mafakitale a polyvinyl chloride kunatsegula zipangizo zatsopano zopangira zikopa zopangira ndikulimbikitsa chitukuko chachikopa chochita kupangakupanga.Phala lopangidwa ndi polyvinyl chloride yokhala ndi plasticizer ndi stabilizer ndi yosavuta kupakidwa utoto, ndipo pambuyo pakupaka ndi gelatinized, imatha kupangidwa kukhala mitundu yambiri yazinthu zowoneka ngati zikopa posindikiza, kusindikiza kapena kusindikiza ndi kusindikiza.Kupumira kwake komanso kutulutsa chinyezi kumagwirizana ndi zikopa zachilengedwe, ndipo zimakhala ndi mphamvu zina komanso kukana kwa abrasion, makamaka ndizosavuta kupanga, zopangira zambiri, mtundu wamtundu wamtundu, wosavuta kudula ndikugwiritsa ntchito, kulemera pang'ono, kukana madzi, mtengo wotsika, kotero imagwiritsidwa ntchito kwambiri pakukongoletsa mkati mwagalimoto,mipando yamagalimotondi zina mafakitale zipangizo.

Ndi chitukuko cha mitundu pulasitiki ndi processing luso, chikopa yokumba amapanga zosiyanasiyana mankhwala angapo.The zopangira ❖ kuyanika wosanjikiza ndi polyamide, polyurethane, polyolefin, etc. KomansoZithunzi za PVC, zida zopangira zokutira zimagwiritsidwanso ntchito.Palinso mitundu yambiri ya nsalu zoyambira, monga nsalu zathyathyathya, chinsalu, nsalu zoluka, milu, nsalu zosalukidwa ndi zina zotero.Mitundu yosiyanasiyana ndi mitundu yopangira zikopa zopanganso zimasiyananso ndi njira yopaka ndi gelation ya nsalu yoyambira pamwamba wosanjikiza, komanso dongosolo la kumaliza, monga embossing, kusindikiza, chithandizo chapamwamba komanso kapangidwe ka mankhwala opangira mankhwala.

Kupanga kumaphatikizapo mankhwala opangira nsalu, kukonzekera zomatira, zokutira, laminating, gelation, chithandizo chapamwamba, embossing, kuzirala, ndi kupiringa.Pali njira zinayi zazikulu zopangira:

Njira yokutira yolunjika

Zomatirazo zimakutidwa mwachindunji pansalu yoyambira kale ndi squeegee, kenako imapangidwa ndi gelled ndi pulasitiki mu bokosi la pulasitiki, ndiyeno imasindikizidwa ndikukhazikika kuti ipeze chomaliza.Njirayi imatha kutulutsa mitundu yonse ya zikopa zopangira wamba, zikopa zopanga filimu komanso chikopa chopangidwa ndi thovu pamunsi pansalu.

Njira yosamutsira zokutira

Imatchedwanso njira yosalunjika yokutira.Phala lokutidwa pa chonyamulira (kutulutsa pepala tepi kapena zitsulo zosapanga dzimbiri tepi) ndi chodzigudubuza n'zosiyana kapena scraper, ndipo pambuyo gelation, nsalu maziko ndiye laminated pa gelated zinthu wosanjikiza popanda mavuto, ndiyeno pulasitiki, utakhazikika ndi peeled. kuchokera kwa chonyamulira, ndiyeno pambuyo mankhwala, ndipo chomalizidwa analandira.Njira imeneyi ndi oyenera kupanga nsalu zoluka kapena sanali nsalu zochokera thovu yokumba chikopa ndi wamba yokumba chikopa.

 Calender ndi laminating njira

Malinga ndi zofunikira za formula, utomoni, plasticizer ndi zinthu zina zofananira zimayezedwa ndikuyikidwa mu makina okanda kuti asakanize molingana, kenako amatumizidwa ku kalendala yodzigudubuza kapena ma roller anayi (onani makina apulasitiki owerengera mu makulidwe ofunikira ndi m'lifupi mwake). filimuyo, ndi laminated ndi preheated m'munsi nsalu, ndiyeno embossed ndi utakhazikika kupeza chomalizidwa.chikopa cha microfiber chochita kupangandi maziko osiyana a nsalu.Pofuna kupititsa patsogolo kuwala kwa nsalu yoyambira ndi filimu, zomatira nthawi zambiri zimagwiritsidwa ntchito pansalu yoyamba.

Extrusion lamination njira

The utomoni, plasticizer ndi wofananira wothandizira zimasakanizidwa bwino mu kneader, ndiyeno extruded mu filimu wosanjikiza makulidwe ena ndi m'lifupi ndi extruder, ndiyeno laminated ndi preheated m'munsi nsalu pa atatu-wodzigudubuza kuumba makina, ndiyeno anamaliza. mankhwala amapezedwa ndi preheating, laminating, embossing ndi kuzirala.

Bensen kampani yopanga zikopa zoteteza zachilengedwe ndizowonachikopa chochita kupanga, makamaka opangidwa ndi utomoni, monga: polyurethane wochezeka zachilengedwe, polyurethane utomoni (TPU), etc., moyo utumiki kwenikweni yaitali kuposa chikopa.Ubwino wa chikopa chochita kupanga chopangidwa ndi Bensen: Choyamba, chikopacho chimakhala ndi mphamvu zabwino zowonongeka, zosavuta kung'amba, zolimba;chachiwiri, kukana dzimbiri, ntchito yabwino yolimbana ndi abrasion;chachitatu, palibe fungo losasangalatsa, ndipo ali ndi antibacterial, anti-mildew, anti-moth, popanda zinthu zovulaza, makhalidwe a chilengedwe.
