Khadka filimka TPU ayaa si wanaagsan loogu qaabeeyey inuu soo saaro filimka hotmelt TPU, filim laminating TPU iyo filim TPU hufan oo heersare ah.Khadku wuxuu aqbalaa labadaba heerkul sare iyo heerkul hooseeya TPU resins, waxayna ku socon kartaa noocyada kala duwan ee alaabada filimka TPU.
TPU xariiqda fidinta filimka waxaa lagu qalabeeyaa qalab-qaadayaal heer sare ah si ay u buuxiyaan shuruudaha hab-socodka ee polymer-ka-kulka.Nidaamka xakamaynta heerkulku wuxuu leeyahay saxsanaan sare si loo hubiyo tayada tayada sare leh ee filimka TPU iyo sidoo kale ilaalinta awoodda ugu fiican.Soo-dejisiyuhu wuxuu aqbalaa inuu socodsiiyo filimka siidaynta ama warqadda la sii daayo sidii agabka taageerada ee duubista filimka TPU.Waayo-aragnimadayada farsamo iyo aqoontayada waxay noqon doontaa dheeraad ah xalka khadka ee maalgashiga macaamiisheena.
Habka wax soo saarka ee khadka filimka TPU waxaa ka mid ah maaraynta polymers, extrusion, shaandhaynta, dhinta T fidsan, tuurista, socodsiinta qulqulka hoose iyo dabaysha.Extruders-yada waxaa si gaar ah loogu talagalay farsamaynta polymer-ka-kulka iyadoo si buuxda loo tixgalinayo sifooyinkeeda laastikada.Rollers-yada hagaya waxaa lagu dahaadhay Teflon ujeedo liddi ku ah dhegdheg.Khadka wax soo saarka oo dhammaystiran wuxuu ku dhexjiraa nidaamka xakamaynta PLC si fudud oo degdeg ah loogu shaqeeyo.Mashiinka waxa kale oo nashqadeeyay fikradda modulka ah ee gaadiidka badda fudud iyo rakibaadda, fiilooyinka fudud iyo cillado yar.
1) Cabirka mishiinka wuxuu noqon karaa macaamiil la sameeyo marka la codsado.
2) Dhammaan rollers-ku waa ka-hortagga dhejiska oo leh daahan Teflon, oo ku habboon filimka TPU
3) Waxaa lagu qalabeeyay qalab-fure si loo sii daayo substrate-ka warqadda
4) Mashiinku wuxuu awood u leeyahay inuu soo saaro xaashida TPU qaro weyn iyo dhumucdiisuna waxay noqon kartaa 0.50mm
Polyurethane Thermoplastic waxaa loo yaqaan TPU, waa filim dabacsan oo leh dherer sare iyo astaamo iyo astaamo ka sarreeya inta badan filimada polyolefin.Sidaa darteed TPU inta badan waa doorasho aad u fiican codsiyada filimada ee baahida badan leh.Alaabooyinka filimka TPU waxay leeyihiin noocyo kala duwan
Alaabooyinka filimka TPU waxay leeyihiin codsiyo kala duwan sida hoos ku xusan:
1) Warshadaha dharka: dharka isboortiga, dharka dabaasha, nigisyada, koofiyadaha, kabaha
2) Warshadaha caafimaadka: galoofyada, labiska qalliinka, xaashida sariirta
3) Dalladda, shandad gacmeed, bac maqaarka ah, shandad, teendho, xirmada ciyaaraha
4) Qalabka qurxinta baabuurta, qalabka dhismaha
